Private Peptide Tracking on iPhone

“Local-first” means the sensitive details that make up your routine remain on your device instead of being stored in PepTrack’s cloud database.

What stays on the device

The current PepTrack privacy policy identifies routine details as local data. That includes logs, user-created schedules, reminders, personal notes, settings, and custom entries.

Deleting the app removes its local data from the device. Before deleting any local-first app, consider whether you need to retain a record through any export options the app provides.

What limited data may leave the device

PepTrack’s published policy describes an optional username and onboarding-completion status stored through Supabase. It also describes anonymous product analytics through PostHog and advertising attribution through Meta.

Those services should not receive routine logs, custom names, notes, or Apple Health values. The privacy policy provides the current details and contact process for data questions.

Apple Health is optional

If you enable Apple Health access, PepTrack can read and write weight data with your permission. The published policy states that this data remains on your device and in your own Apple Health store and is excluded from advertising and analytics.

Questions to ask any routine tracker

• Does the app require an account?
• Are routine logs stored locally or on a server?
• Which analytics and attribution services are used?
• Can permissions be revoked?
• How can server-stored account data be deleted?
