Privacy policy

Effective August 14, 2026

Peptrend has no account system, no servers of its own, no analytics and no advertising. It collects nothing about you. Everything you log is stored on your device, and — if you leave iCloud on — in your own private iCloud database, which we cannot read.

What we collect

Nothing. The app's privacy manifest declares no collected data types and no tracking, and it contains no third-party SDKs and makes no network requests of its own.

There is no sign-up, no login, no email address, no device identifier sent anywhere, and no usage analytics. We do not know that you installed the app, and we cannot see a single one of your weigh-ins.

Where your data lives

On your device

Weigh-ins, doses, vials, goals, schedules and settings are stored in a local database on your iPhone or iPad. Deleting the app deletes that database.

In your iCloud

If iCloud is enabled on your device, that database is mirrored into the privatedatabase of an iCloud container tied to your Apple Account. This lets your own devices stay in sync. Apple operates this storage under Apple's privacy policy; the developers of Peptrend have no access to it, no console view of it, and no ability to read, export or recover it. Turning off iCloud for Peptrend in iOS Settings stops the mirroring.

Apple Health

Peptrend reads from Apple Health, and writes body mass back to it. Which types it reads depends on what you have switched on, and nothing is read until you grant permission. Your doses, vials, goals and schedules are never sent to Apple Health at all.

Reading your weight. Peptrend imports body-mass samples so weigh-ins already on your device appear in the app. Samples read this way are copied into the same local database described above.

Reading fitness metrics. Athlete Mode arrives in version 1.4.0, which is not on the App Store yet; this paragraph describes it as it will ship. Athlete Mode is off until you switch it on. When you do, Peptrend asks Apple Health for ten more types and charts them beside your dose history: VO₂ max, heart rate variability, resting heart rate, cardio recovery, walking heart rate average, respiratory rate, blood oxygen, sleeping wrist temperature, exercise minutes and active energy. They are requested at the moment you turn the mode on and not before — leave it off and the permission sheet lists body mass alone, and the app reads none of the ten. Peptrend only reads those ten; body mass stays the single type it ever writes. Nothing else is asked for at all: no body fat, no lean mass, no waist, no nutrition, no steps, no sleep stages, no menstrual or reproductive data, no clinical records and no individual workout records. What comes back is charted on your device and goes no further; we have no server for it to reach.

Writing. If you also grant write permission, a weigh-in you type into Peptrend is saved back to Apple Health as a body-mass sample, so your other apps show the same number. Only entries you type here are written back: a weigh-in that came from Apple Health is already there, and one that arrived in a JSON import belongs to whichever app exported it. Editing a weigh-in replaces the sample Peptrend wrote, because Health samples cannot be changed in place. Deleting a weigh-in inside Peptrend does notremove the sample from Apple Health — delete it in the Health app if you want it gone from there too.

Read permission and write permission are separate. Either can be refused, and either can be revoked at any time in the Health app under Sharing → Apps, which lists every type Peptrend has asked for. Refusing write permission stops the write-back and changes nothing else about the app. Turning Athlete Mode off stops the fitness reads on its own.

Purchases

Subscriptions and the lifetime purchase are handled entirely by Apple's App Store. Peptrend asks Apple whether a purchase is active; it never sees your payment details, billing address or Apple Account. Apple's own privacy policy governs the transaction.

Notifications

The optional dose reminder is a local notification scheduled on your device. There is no push server and nothing about your schedule leaves the phone.

Files you import or export

Import and export happen through the iOS document picker and share sheet. The file is read or written directly on your device or in whatever location you choose. Nothing passes through us.

Children

Peptrend is not directed at children and is not intended for anyone under 18.

Your rights

Because we hold no data about you, there is nothing for us to disclose, correct, export or delete on request. You already hold every copy. To erase everything, delete the app and, if you used iCloud sync, remove Peptrend's data from iCloud in iOS Settings. The app also has a "Reset all data" control in Settings.

Questions about this policy go to support@fluctusltd.info. Please do not attach your log; we have no copy of it and no use for one.

Changes to this policy

If the app ever starts collecting anything, this page will say so before that version ships, and the effective date above will change.
