Terms of Service

Last updated: October 15, 2026

Effective for existing accounts: November 20, 2026. New accounts, and anyone using AstroLina without one, are bound from October 15, 2026.

Welcome to AstroLina. These Terms of Service ("Terms") are an agreement between you and Lina Grosso, operating as AstroLina ("AstroLina", "we", "us"). AstroLina is a small, two-person project. By using AstroLina or creating an account, you agree to these Terms. If you don't agree, please don't use the service.

If you're a consumer, you keep every right the law where you live gives you (see Your statutory rights). A few clauses don't apply if you live in Quebec, and two don't apply to consumers in the EU, the EEA or the UK; each one is marked where it appears.

Questions about these Terms? Email contact@astrolina.org. For help with the app itself, support@astrolina.org.

What changed on October 15, 2026

These Terms replace the version dated August 23, 2026, which you can still read here. If you opened your account before October 15, 2026, they apply to it from November 20, 2026. If you live in Quebec, if the law where you live otherwise requires your agreement to a change like this, or if our email about this update didn't reach you, they apply to it only once you accept them in the app or at checkout, and never before November 20, 2026. Either way, a purchase you make on or after October 15, 2026 is made under these Terms, which you accept at checkout.

If you don't agree, tell us by December 20, 2026: reply to our email about this update or write to contact@astrolina.org. We'll then end your plan, or you can close your account, at no cost, and we'll refund the unused part of anything you paid ahead (for a lifetime purchase, a share of what you paid for it, in proportion to the time left of the 36 months after you bought it). If you hold the lifetime purchase, you can instead keep it under the Terms you bought it under: tell us the same way, by the same date. The Privacy Policy changed on the same day: see what changed there.

The main changes, what they mean for you, and why:

1. What AstroLina is

AstroLina is web-based astrocartography software. "The service" means the app at maps.astrolina.org and this website, astrolina.org. You can use the app without an account. Creating a free account unlocks the Advanced toolkit, and a paid Pro tier unlocks the professional toolkit (see Paid features and billing).

AstroLina runs in a current web browser. Some tools need more: the street-level view follows the way you point your device only on a phone or tablet with orientation sensors, and auto-translation needs a browser with a built-in translator.

Feature names. Street and Sherlock are our names for the street-level view and birth-time rectification. The rest of these Terms describes them by what they do, and renaming a feature is not a material change (§13). Some tools these Terms describe, these two among them, may not be in the app for you yet, and a tool that isn't in the app for you isn't part of any plan you buy.

2. Who we are

We are Lina Grosso, operating as AstroLina, based in Toronto, Canada.

contact@astrolina.org is also our single point of contact under the EU Digital Services Act, for authorities and for anyone using AstroLina. Write to us in English. Messages that reach our inbox are read by a person; we don't rely on automated tools alone.

3. Your account

4. Acceptable use

Please use AstroLina lawfully and fairly. You agree not to:

If you break these rules, we may act as Content you store and Suspension and termination describe — always with reasons, and a way to contest it.

5. Content you store

"Content you store" is what you keep with us when sync is on: your charts and their notes, journal entries and saved pins, saved reports and their images, and your Custom theme, including any names you give them. It's yours (see Your data and content).

We don't monitor it. We don't browse your content or scan it for what it says. Our software handles it only to store and sync it and to produce the counts the Privacy Policy describes. A person looks at a specific item only when someone sends us a notice about it, when you ask us to (for example, for support), when we need to fix a fault, deal with a security incident or protect someone's safety, or when the law requires it. AstroLina has no public pages: nothing you store is shown to other users, and share links and exports carry their content themselves rather than pointing to anything we host.

What isn't allowed. Don't store content that is illegal, that infringes someone else's rights, or that holds other people's personal information you have no right to hold.

Reporting illegal content. If you believe something stored with AstroLina is illegal, email contact@astrolina.org with:

We confirm that we've received it, a person reviews it — we use no automated moderation — and we tell you what we decided and how you can challenge that decision. If something gives us reason to suspect a crime that threatens someone's life or safety, we tell the authorities, as the law requires.

What we may do, and how we tell you. If we find content is illegal or breaks these Terms, we may remove it or make it unavailable, pause your sync, or suspend or close your account. Each step is proportionate to the problem. Unless the law prevents it, we email you a statement of reasons: what we did and for how long, the facts we relied on, whether it followed a notice, the law or clause of these Terms involved, that a person made the decision, and how to contest it. To contest it, reply to that email: we'll look at it again and tell you the outcome. You can also go to court at any time.

6. Not professional advice

AstroLina is for personal insight, learning, and entertainment. It is not a substitute for professional medical, psychological, legal, financial, or other advice. Decisions you make based on the software are your own.

Rectified birth times

A birth time found by birth-time rectification is an estimate deduced from the clues you give, not a record. It is only as good as those clues: a confidently wrong clue gives a confidently wrong answer, and another method may well land on a different time. When you adopt a time, the chart's source rating is set to C (source unknown, or rectified) and a short note is added to the chart. Keep that rating whenever you rely on the chart or pass it on. Share links carry a chart's time but not its rating or notes, so tell the person you share it with that the time was rectified. A share link made while you're trying a time carries that time as if it were known. If you work on someone else's birth time, ask them before entering events from their life.

The street-level view

On a phone or tablet, the street-level view can follow the way you point your device. Don't use it while driving, cycling, or crossing a road, and stay aware of your surroundings while you look around. It is not for navigation: a device compass is typically accurate only to about 5–15°, the view assumes you are standing at the chart's origin (it never reads your actual location), and its buildings come from community map data that can be incomplete, wrong or out of date. The bearings it shows come from the chart, not from the compass.

7. Open source, licences and intellectual property

The core of AstroLina is free, open-source software, released under the GNU Affero General Public License v3.0 (AGPL-3.0). You're welcome to use, study, and build on that code under the terms of that licence — see git.astrolina.org.

These Terms govern your use of the hosted service (this website and the app, including Pro features), which is separate from the open-source licence. The AstroLina name, logo, and our proprietary add-ons are ours and aren't granted to you by these Terms or by the open-source licence.

Map data (© OpenStreetMap contributors), map styles, the World Magnetic Model and other third-party material belong to their owners and are used under the licences listed in the app's Credits. Nothing in these Terms restricts what those licences allow you to do.

Suggestions you send us. If you send us a suggestion — a translation report with the wording you think is right, say — you let us use it to improve AstroLina, free of charge, including in the open-source core under its licence. What we keep of a report, and for how long, is in the Privacy Policy. Acceptable use applies to what you send, as to everything else.

8. Your data and content

The birth details, charts, journal entries, reports, and other content you create are yours. If you're not signed in, they stay in your browser. You're responsible for the information you enter, including having any necessary permission to enter details about other people — for example, a client's name and birth details in a chart or a report you prepare for them. What we collect, and why, is described in our Privacy Policy.

Sync

You choose, on each device. When you sign in on a device, we ask how that device should keep your work: Sync with my account (marked Recommended; pressing Enter chooses it) or Keep on this device only. Nothing from that device is synced until you choose one. Devices that were already signed in before we added this choice keep the setting they had. You can change it for each device on your account screen at any time.

What we store with sync on. The charts in your library, with everything each holds — including its notes and source rating, a home location if you set one, and both people's birth details in a relationship chart such as a composite or Davison chart. On the Pro tier, also your journal entries and saved pins, saved reports (with any notes and map images), and your Custom theme. The Privacy Policy lists every detail. If your Pro plan ends, your Pro content stays on our servers but stops syncing until Pro comes back.

Deleting. Deleting an item in the app on a device that syncs it removes it from our servers too (for Pro content, while you're on Pro). Delete it on a device while that device's sync is off, and it's removed from our servers when you turn sync back on there, if the device had synced it before. Otherwise — after your Pro plan ends, say — email us and we'll delete it, or delete your account. Your Custom theme is removed from our servers once it has no changes of your own: when you close the theme's settings with nothing changed from the look it started from — whichever look that is, and whatever the theme's name — a device that syncs it removes it the next time it reaches us, and your other devices drop their copy as the Privacy Policy describes. A theme with no changes is just its look: while you have Pro, the device you closed it on keeps showing that look in its place, and your other devices show the look their own copy started from. Reset, in the theme's own settings, clears your colours and styles, so closing the settings after it removes the theme. We keep only the date a theme was removed, so that an older copy on another device can't bring it back, and that date goes when your account does. To have your theme deleted any other way, or if you're no longer on Pro, email us and we'll delete it. Deleting your account removes all of your synced content from our servers (and from our backups within 30 days, as the Privacy Policy explains).

Turning sync off. Your account screen lets you switch content sync off, keeping the charts and other content you create from then on only in that device's browser. Your account itself is unaffected — it still unlocks everything your plan includes, and your session, billing, and account settings work normally; the switch governs your content, as the Privacy Policy describes. That mode is your choice and comes with a trade-off: while sync is off we hold no copy of your new work, so if the device is lost, or its browser data is cleared, that work can't be recovered by us. Back up accordingly, or turn sync back on to upload it.

Kept only on your device. The case files you build for birth-time rectification — your clues and answers — stay in that browser only, in plain text. They are never sent to us, synced or backed up by us. Anyone who uses that browser can read them, so on a shared computer, clear them when you're done: Clear clues deletes a chart's clues and answers at any time, keeping only what you'd need to undo an adopted time. A case file is also removed after you delete the chart it belongs to — the next time the app opens, or, if that was the last chart in your library, once the library has a chart again — and when you delete your account on that device.

AstroLina can create a link that contains a chart's birth details, so the person you send it to can open the same chart. Sharing such a link is your choice and your responsibility: the details travel in the link itself, recipients get their own copy, and a link can't be recalled once sent. Don't share links containing someone else's birth details without their permission.

Theme share codes work the same way. A code holds your Custom theme and its name; whoever has it gets their own copy, and it can't be recalled. We never see it.

Reading for other people

If you use AstroLina professionally and store a client's information with us — their name and birth details in a chart, or in a report you prepare for them — you decide what to collect and why; we only hold it and sync it back to you, on your instructions, as described in our Privacy Policy. You are responsible for having the right to enter those details and for telling your clients how you use tools like this one. That includes events from their lives that you enter as clues for birth-time rectification, even though those stay on your device. We don't contact your clients or use their information for anything of our own (apart from the counts the Privacy Policy describes), and we delete it when you delete it or close your account.

Our processing terms for client information. When you store personal information about other people with us in the course of your work, these terms apply between you and us, as part of these Terms. They are written to meet Article 28 of the GDPR and the UK GDPR, and Canada's and Quebec's rules for service providers. You don't need to sign anything.

9. Paid features and billing

The core of AstroLina is free and open source, and a free account unlocks the Advanced toolkit. The Pro tier is a paid upgrade. We won't charge you without your clear agreement, and here is how paying for Pro works:

Cancelling

You can cancel any subscription, or stop paying monthly for the lifetime purchase, online at any time, without writing to us. On your account screen, choose Cancel plan here, then Cancel plan now. The same steps start at astrolina.org/cancel. On the form you choose the type: an ordinary cancellation, at the earliest date your plan can end, or an extraordinary one, for good cause and with immediate effect, with your reason. Either way, your plan is set to end at that earliest date; for an extraordinary one, we reply within 14 days about ending it at once. We confirm every cancellation by email straight away, with what you sent, when we received it and the date your plan ends.

If you live in Quebec, you can end an annual plan, or close your account, at any time, and we refund what you paid ahead for service you won't receive: unused time counted in days, prepaid or converted Pro time at the price it was converted at, and for a lifetime purchase a share of what you paid for it, in proportion to the time left of the 36 months after you bought it. Tell us when you cancel or close your account.

You can still use Manage billing on the account screen to update your card or see your invoices; cancelling is done with Cancel plan here, not there.

Price changes

If we change the price of a plan you're subscribed to, we email you at least 30 days before your next renewal at the new price, with the old and new price, the date it starts, and your options. It applies from that renewal on, never partway through a period you've paid for, and on an annual plan never before your year ends. You can refuse it: cancel before it applies, at no cost, or, up to 30 days after it applies, tell us you refuse it, and we end your plan that day and refund the part of the period charged at the new price that you don't use, counted in days (see Changes).

Free trials and discounted periods

We may offer a free trial. Its length and terms are shown at checkout before you start it; a payment method is required, and unless you cancel before the trial ends, your subscription begins and your payment method is charged. Trials are limited to one per account; deleting an account to start a fresh trial isn't in the spirit of the offer, and we may decline to extend one.

We email you 2 to 10 days before a free trial or a discounted period ends, with the date it ends and the price that applies afterwards, so you can cancel in time if you'd like to.

Right of withdrawal (EU, EEA and UK)

If you're a consumer living in the European Union, Iceland, Liechtenstein, Norway or the United Kingdom, you can withdraw from a purchase within 14 days, without giving a reason. Your purchase confirmation sets out this right and the model form below.

How long you have. The 14 days end 14 days after the day of your first payment: the day you buy, or — after a free trial — the day the trial turns into a paid plan. While a trial is still free you can withdraw at any time; nothing is charged. If you're paying monthly for the lifetime purchase, the 14 days run from your first payment, since that is when the purchase was made. Renewals don't start a new period. Switching to a different plan is a new purchase, with 14 days of its own.

How to withdraw. Either way works:

It's enough to send your withdrawal before the 14 days end.

What happens next. If you use the online function, we email you an acknowledgement straight away, with what you sent and the date and time we received it; if you write to us, we acknowledge it as soon as we read it. If your billing address, or where you're connecting from when you withdraw, is in the EU, the EEA or the UK, Pro ends at once and no further payments are taken (if you're paying monthly for the lifetime purchase, the remaining payments stop). Otherwise we look at your withdrawal and reply within 14 days, and we may ask you to confirm where you live: no payment is taken after we've read your withdrawal, and Pro ends when we refund you.

If you're a consumer living in the EU, the EEA or the UK, we refund everything you paid for that purchase, including tax, to your original payment method, within 14 days of receiving your withdrawal, at no cost to you. When the purchase you withdraw from was an upgrade that replaced a plan you had, we refund what you paid for the upgrade and give you back the time that was left on the plan it replaced. Pro starts as soon as you buy — you agree to that at checkout — and using it during those 14 days doesn't cost you the refund.

Model withdrawal form

(Complete and return this form only if you wish to withdraw from the contract.)

To Lina Grosso, operating as AstroLina, 1 Lomond Dr, Toronto, ON M8X 2Z3, Canada, contact@astrolina.org:

I/We (*) hereby give notice that I/We (*) withdraw from my/our (*) contract for the provision of the following service: AstroLina Pro (plan: ____________),

ordered on (____________),

name of consumer(s): ____________,

address of consumer(s): ____________,

signature of consumer(s) (only if this form is sent on paper): ____________,

date: ____________.

(*) Delete as appropriate.

Refunds

If you live in Quebec, the next sentence does not apply to you.

Apart from the right of withdrawal, the refunds promised in Price changes, §8, §10, §12 and §13, and any refund the law gives you, payments aren't automatically refundable.

We're people, not a wall, though: if something went wrong, email support@astrolina.org and we'll do our best to make it right. If you live in Quebec, Cancelling sets out what we refund when you end a plan you paid ahead.

10. Availability, changes to features, and "as is"

We work hard to keep AstroLina running and accurate, and we keep improving it. The service can be interrupted now and then, for maintenance or by problems beyond our control.

Changing features. We may add, change or remove features. A change follows Changes to these Terms: it needs a valid reason, and it never costs you more for what you've already paid for. We tell you about changes to the features you pay for clearly, in the app (in What's new) or by email. If a change removes or reduces a feature you've paid for, that's a material change: we tell you by email and in the app at least 30 days ahead, and you can leave at no cost, with a refund of the unused part of what you paid ahead (how).

If we ever close the service. We'll tell account holders by email at least 60 days ahead, or, if an event we could neither foresee nor prevent makes that impossible, as far ahead as we can. We'll refund the unused part of any period you've paid for, counted in days, and for a lifetime purchase we'll refund a share of what you paid for it, in proportion to the time left of the 36 months after you bought it. Until it closes, you can ask us for an export of your data.

If you live in Quebec, or you're a consumer in the EU, the EEA or the UK, the next paragraph does not apply to you.

To the fullest extent permitted by law, the service is provided "as is" and "as available," without warranties of any kind. We don't guarantee that it will be uninterrupted or error-free, or that calculations will suit any particular purpose.

Nothing in these Terms limits the legal guarantees, warranties or conditions that consumer law gives you, including the guarantee that a service you pay for conforms to the contract.

11. Limitation of liability

If you live in Quebec, or you're a consumer in the EU, the EEA or the UK, the next paragraph does not apply to you.

To the fullest extent permitted by law, AstroLina and the people behind it won't be liable for any indirect, incidental, special, or consequential damages, or for lost data or profits, arising from your use of (or inability to use) the service. Where liability can't be excluded, it is limited to the greater of the amount you paid us in the 12 months before the claim and CA$100.

If you're a consumer in the EU, the EEA or the UK, we're responsible for loss or damage you suffer that is a foreseeable result of our breaking these Terms or failing to use reasonable care and skill. We're not responsible for loss that wasn't foreseeable when you accepted these Terms.

Nothing in these Terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud, for harm we cause intentionally or through gross negligence (or, in Quebec, gross fault), or for anything else the law doesn't allow us to limit — including your statutory rights as a consumer.

12. Suspension and termination

You can leave at any time. Delete your account from the account screen; for paid plans, see Cancelling and what deleting your account ends.

When we suspend an account. We may suspend an account, or limit what it can do, while we deal with a serious or repeated breach of these Terms, a legal requirement, or a risk to the service or other people. We tell you why, with a statement of reasons as described in Content you store, and how to contest it. Unless it's urgent or the law prevents it, we warn you first and give you a fair chance to put things right.

When we close an account. We close an account only if it seriously or repeatedly breaks these Terms, or for another serious reason (such as a court order, or closing the service), and never at a moment chosen to harm you. We give reasons in the same way. Unless you've broken these Terms, we give at least 60 days' written notice by email (or, if a court order or another event we could neither foresee nor prevent makes that impossible, as much notice as we can) and refund the unused part of any period paid for, counted in days (for a lifetime purchase, a share of what you paid for it, in proportion to the time left of the 36 months after you bought it).

Sections that by their nature should survive (such as intellectual property, disclaimers, and limitation of liability) continue to apply.

13. Changes to these Terms

This is how we change these Terms, and what you can do when we do.

A material change is one that (a) adds to what you must do or pay, or reduces what we must do; (b) removes or reduces a feature you have paid for; (c) uses personal information for a new purpose, collects a new kind of it, shares it with a new kind of recipient or in a new country, or keeps it longer; or (d) makes it harder to use your rights, cancel or leave. Clearer wording, corrections, new contact details, a renamed feature, a new optional feature that collects nothing new, and anything that only adds to your rights are not material changes.

What we may change. Only these parts of our agreement:

What we won't change for time you've paid ahead. For the current year of an annual plan, and for the lifetime purchase (including while you pay for it monthly), we won't change the price, the length, or the Pro toolkit as a whole beyond minor changes.

If you live in Quebec, the next sentence does not apply to your annual plan or lifetime purchase.

If a provider we depend on ends something and we have to remove a significant part of what you paid for, you can end that purchase and get a refund of the unused part, as under "Refuse" below, instead of keeping it as it is.

If you live in Quebec and a provider's change makes part of what you paid for impossible to provide, we tell you, and you can end the purchase with a refund of the unused part (for a lifetime purchase, a share of what you paid for it, in proportion to the time left of the 36 months after you bought it).

Only for a good reason. We change these Terms only because of: a change in the law, or a decision of a regulator or court; security, or stopping abuse; a provider we rely on changing or ending its service; adding or improving features; fixing mistakes; and, for features, plans and prices only, changes in our costs or in how we package, price and run AstroLina, never beyond what the paragraphs above allow for time you've paid ahead.

Not often. We propose changes to these Terms at most once a month, except changes that take nothing from you (below), changes the law requires, changes needed for security, and changes a provider we rely on forces on us.

How we tell you. Changes that take nothing from you are published here with a dated summary, without an email, and apply when we publish them: corrections such as typos and broken links, clearer wording with the same meaning, new or changed contact details (ours, or those of a representative the law asks us to name) that leave you at least the same ways to reach us, a feature's new name, and changes that only add to your rights. If a change published this way turns out to take something from you, it applies to you only once 30 days have passed after we email you about it, as below. We email your account's address about every other change, at least 30 and at most 90 days before it takes effect, and for a material change we also show a notice in the app. The email sets out each new clause, and for each amended clause both its new text and its text as it read before (for a full rewrite, the whole new and earlier texts), with the date it takes effect and your options below. The notice in the app links to the summary of what changed, which links to the earlier version. We also publish a dated summary at the top of this page and keep the earlier version (see Previous versions). You never have to check this page to find out.

When it takes effect. An emailed change takes effect on the later of the date in the notice and 30 days after you receive it. A change never applies to anything before it takes effect. An account opened after we publish a change accepts it when it signs up.

Your options.

If you live in Quebec, the next paragraph does not apply to you.

If you keep using AstroLina after the change takes effect and haven't refused it, the changed Terms apply to you from that date.

If you live in Quebec, a change made under this section applies to you from the date it takes effect, unless you refuse it and cancel as set out above. (The update of October 15, 2026 is different: because the earlier Terms didn't set out how changes are made, it applies to accounts in Quebec only once they accept it.)

Changes to the Privacy Policy's security and international transfers sections follow this section (§15). Other changes to the Privacy Policy follow its own changes section, which uses the same definition of a material change.

14. Language and translations

Only the English version of these Terms and of the legal, billing and consent wording in the app is legally binding, and only the English version of the Privacy Policy is authoritative. Translations of the app and of this website are there for your convenience. Your rights under the law where you live are unaffected (see Your statutory rights).

The app's own translations. Apart from Auto-translated languages (below), the app's translations are machine-made, with an automated review, and may contain mistakes. That includes the wording you agree to or pay by: where it appears in translation, a note beside it says that only the English version is legally binding, and a button shows the English.

Auto-translated. If you choose an Auto-translated language in the app, your browser translates the app's English wording, Help pages included, on your device. The result may be wrong. The wording you agree to or pay by — sign-up consent, checkout and billing — stays in English, and your charts, notes and places are never translated.

The emails we send are in English. If you use your browser's own "translate this page" feature, that's a service of your browser's maker, not ours; the Privacy Policy explains what it can mean for your information.

15. General

16. Governing law, courts and your consumer rights

If you live in Quebec, the next paragraph does not apply to you.

These Terms are governed by the laws of the Province of Ontario and the federal laws of Canada applicable there, without regard to conflict-of-laws rules. The courts of Ontario can hear disputes about them, but not exclusively: if you're a consumer, you can also bring a claim in the courts where you live, and if we ever need to bring a claim against you as a consumer, we'll bring it there.

If you live in Quebec, the law of Quebec protects you as a consumer, and you can bring a claim before the Quebec courts.

Your statutory rights

Nothing in these Terms takes away a right that the mandatory law of the place where you live gives you as a consumer, including its rules on language, guarantees, refunds and where you can go to court. Where a clause here conflicts with such a right, the right wins.

Before going to court, please write to us at contact@astrolina.org. We'd always rather sort things out directly, and a person will answer.
