Piri: Peptide Tracker — Privacy Policy

Last updated: July 27, 2026

Piri ("the app") is a private, on-device journal for tracking a personal peptide routine. This policy explains what data the app handles and what leaves your device. In short: your health and dosing data never leaves your phone.

Data stored on your device only

Everything you enter — peptides, doses, injection sites, cycles, feel/mood check-ins, baseline metrics, notes, and reminders — is stored locally on your device in an encrypted database. There is no account, no login, and no cloud sync. We never receive, see, transmit, or store this information on any server. If you delete the app, this data is gone.

Data protection

The app can be locked with Face ID / Touch ID and a PIN, and its database is encrypted at rest using the operating system's data protection. Your PIN and recovery code are stored in the device keychain in hashed form.

Apple Health

Piri can optionally exchange body weight, and nothing else, with Apple Health. It is off until you turn it on, and you can turn it off at any time.

• Reading — if you import from Apple Health, the app reads your body-weight samples so you do not have to retype a number your phone already has.
• Writing — if you enable weight sync, weights you log in Piri are saved back to Apple Health so your other apps stay current.

This exchange happens entirely on your device, between Piri and Apple Health. We never receive, transmit, or store your Apple Health data on any server. It is never used for advertising, marketing, or analytics, never shared with third parties, and never written to iCloud. Piri requests no other Apple Health data types. You can review or revoke access at any time in the Health app under Sharing → Apps, and deleting Piri removes its copy of the data from your device.

Limited data handled by third parties

The only information that ever leaves your device is anonymous, and only for these two purposes:

• Purchases & licensing (RevenueCat, Inc.) — when you start a trial, purchase, or restore the one-time unlock, we use RevenueCat to validate the purchase. RevenueCat may process an anonymous app identifier, your device/OS type, and App Store purchase status. It does not receive any of your health, dose, or journal data. See RevenueCat's privacy policy.
• App updates (Expo / EAS Update) — on launch the app may check for a software update, which involves your app version, device model, and OS version. No personal or health data is sent. See Expo's privacy policy.

We do not use analytics or advertising SDKs, and we do not sell, rent, or share your data with anyone.

Not medical advice

Piri is an informational journaling and organization tool only. It is not medical advice and does not recommend, prescribe, endorse, or supply any substance or dose. Always consult a licensed healthcare provider before using any peptide or making any health decision.

Children

Piri is not directed to children and is intended for adults (18+).

Changes

We may update this policy; changes will be posted on this page with a new "last updated" date.
