Privacy Policy

Last updated: May 28, 2026

This Privacy Policy explains how Composure ("we", "our", "the app") handles your information when you use the Composure mobile application. We've designed Composure to collect as little personal data as possible.

1. What we collect

1.1 Information you provide

You can use Composure entirely anonymously. If you choose to enable sync from the Settings screen, you will provide an email address so that we can save your progress across devices and restore it if you reinstall the app.

When you submit a support request via our support form, you provide the information you choose to include (e.g., name, email, message content).

1.2 Information collected automatically

  • Subscription status: When you purchase or restore a subscription, our payment provider (RevenueCat, on top of Apple's App Store) generates an anonymous user identifier to track entitlement. This is not linked to your name unless you enable sync.
  • Crash and error reports: We use Sentry to capture crashes and errors so we can fix bugs. These reports include technical information about the error, your device model, operating system version, and app version. They do not include the content of your lessons or any personal entries you make in the app.
  • Progress data: Your lesson progress, streak, and completion state are stored locally on your device. They are only sent to our servers if you enable sync.

1.3 What we do NOT collect

  • We do not run third-party advertising or marketing trackers.
  • We do not sell your data to anyone.
  • We do not collect contacts, photos, location, microphone, or camera data.
  • We do not have access to your payment card or Apple ID — payments are handled entirely by Apple.

2. How we use information

  • To deliver the lessons, exercises, and features of the app.
  • To verify your subscription entitlement and restore purchases.
  • To sync your progress across devices, if you've opted in to sync.
  • To diagnose crashes and improve reliability.
  • To respond to support requests you send us.

3. Third-party services

We rely on a small number of service providers to run Composure. Each one handles a narrow slice of data described above:

  • Apple App Store — processes all payments and subscription billing. We never see your card details.
  • RevenueCat — manages subscription entitlement using an anonymous identifier.
  • Convex — stores your progress and account data only if you enable sync from Settings.
  • Sentry — captures anonymized crash and error reports.
  • Tally — hosts our support form on the web.

These providers are bound by their own privacy policies and process data on our behalf only for the purposes described above.

4. Data retention

Progress data is kept on your device until you delete the app or reset it. If you enabled sync, synced data is kept on Convex until you delete your account or request deletion. Crash reports in Sentry are retained for up to 90 days. Subscription records are retained for as long as required by Apple and applicable tax law.

5. Your choices and rights

  • Don't enable sync. If you never turn on sync, no account is created and no progress data leaves your device.
  • Delete your account. If you've enabled sync, you can request account and data deletion by contacting us at the email below. We will delete your synced data within 30 days.
  • Manage subscriptions. All subscription cancellations and refunds are managed by Apple in your Apple ID settings.
  • GDPR / UK / California residents: You may have additional rights to access, correct, or port your data. Contact us to exercise them.

6. Children

Composure is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will delete it.

7. International users

Your data may be processed in countries other than the one in which you live, including the United States, where our service providers operate. We rely on the safeguards offered by those providers (including the EU Standard Contractual Clauses, where applicable).

8. Changes to this policy

If we change this policy, we will update the date at the top of this page and, for material changes, notify you in-app.
