PillStreak

Last updated: November 10, 2026

PillStreak is a study app for nursing students. This policy explains what data the app collects and what it does with it. If you have questions, contact us at hello@petrou.ai.

What we collect

• If you use the app as a guest (the default): nothing leaves your device. Your study progress, medication mastery, streaks, graduated medications, trophies, and finals attempts, is stored only on your device. We do not collect it, and we cannot see it.
• If you sign in with Apple: Apple shares your email address with us (Apple may use a private relay email instead of your real one) and an Apple user ID. Your study progress is then backed up to our database (Supabase) so it can sync and be restored. We use that data only to back up and restore your progress.
• If you send feedback: we collect your message, the category you picked, your email address, the app version, your iOS version, and any screenshots you attach. Feedback is stored in our database so we can act on it, including corrections to medication content, which is how we keep the medication information accurate.

What we do not collect

• No ads, no advertising identifiers, no analytics, no crash reporting, no location, no contacts, no photos (except screenshots you choose to attach to feedback), and no health information. The app stores study progress only, never medical records or patient data.
• We do not sell your data. We do not share it with advertisers or data brokers. The only third party that receives anything is Supabase (our database, for signed-in backup and feedback storage).

Deleting your data

• Guest data lives only on your device. Delete the app and it is gone.
• Signed-in users can delete their account in the app: Settings, Account, Delete Account. Two-step confirm. Deleting removes the account, backed-up progress, and feedback, and clears local data on the device.

Children

PillStreak is designed for adult nursing students. We do not knowingly collect personal data from children under 13.

Changes to this policy

If we change what we collect, we will update this page and note the change in the app's What's New screen.
