Privacy Policy

Last updated: 24 September 2026

AnatomyMatch 3D is a study app for anatomy students. This policy describes what it collects, why, how long it is kept, and how to get rid of it.

What we collect

Information you give us

Account — your email address and a display name.
Study setup — the course you are taking and, if you enter one, your exam date. Used to schedule review and build your study plan.
Preferences — whether you want reminders and at what time.
Support messages — anything you send us through the in-app "report a problem" form, including the diagnostic details shown to you on that screen before you send it.

Information created by using the app

Study activity — which cards you reviewed, how you graded yourself, quiz answers and scores, and where you tapped on an image (the coordinates, and whether the tap was correct). This is what drives scheduling and your weak-areas report.
Social features — study buddies you add, challenges you send, and referral links, if you use them.
Purchases — which subscription you hold and when it expires. Your payment details are handled by Apple or Google and never reach us; we receive only the fact of the purchase.

Information collected automatically

Diagnostics — your IP address, browser or device user agent, and the app version, recorded with activity and sign-in events.
Errors — when something breaks, the error message, the stack trace, the screen you were on, and your device and OS version.

What we don't do

We don't sell your personal information.
We don't show third-party advertising, and we don't use your data to build an advertising profile of you.
We don't collect location data.

Why we collect it

Purpose	What it uses
Running the app you asked for	Account, study activity, purchases
Scheduling your reviews	Study activity, exam date, course
Reminders, if you turn them on	Preferences, email or device token
Fixing bugs and keeping the service up	Diagnostics, errors
Detecting abuse of accounts	Sign-in events, IP address
Understanding which features help people learn	Aggregate counts (see below)

How long we keep it

Data	Kept for
Study activity, taps, quiz results, IP and user agent	90 days
Sign-in and account-security events	365 days
Resolved error reports	180 days
Your account, progress and purchase record	Until you delete your account
Daily usage totals with no one in them	Indefinitely

That last row is the one worth explaining. After the 90-day window we still want to know whether the app is working — whether people are studying more this month than last. So each day we write down counts: how many reviews happened, how many quizzes, how many people were active. Those rows contain no user IDs, no IP addresses and nothing that points at a person. They are what survives; the per-person records are deleted.

Support conversations

If you use in-app support, your question may be sent to an AI service (Anthropic) to generate an answer. Support conversations are used only to help you and to improve the app's answers — not to train anyone's models, and not for advertising.

Who else touches it

We use a small number of service providers to run the app. Each one gets only what it needs:

Provider	What they handle
Supabase	Sign-in, and the database your account lives in
Render	The servers the app runs on
Sentry	Error reports, so we find out when something breaks
Apple / Google	Payments and subscription management
Anthropic	In-app support answers, if you use support
Resend	Email we send you (reminders, account mail)

How your data is protected

Traffic is encrypted in transit, and data is encrypted at rest by our infrastructure provider. Passwords are handled by our authentication provider and are never visible to us in readable form. Access to the production database is limited to the people who operate the service.

No service is perfectly secure, and we will not claim otherwise. If a breach affects your data we will tell you.

Your choices

See your data. Ask and we will send you a copy of everything tied to your account.
Delete your account. Ask and we delete your account, progress and activity. Anonymous daily totals, which contain nothing about you, remain. Records we are required to keep for tax or accounting reasons remain for as long as the law requires.
Turn off reminders at any time in Settings.
Correct anything wrong in your profile, in Settings.

Email support@anatomymatch3d.com for any of these. We will respond within 30 days.

Children

AnatomyMatch 3D is built for college students and is not directed at children under 13. We do not knowingly collect information from children under 13. If you believe a child has given us information, email us and we will delete it.

Changes

If this policy changes in a way that affects you, we will tell you in the app before the change takes effect. The date at the top always reflects the current version.
