## Every injection, on the body map.

The body map records the site with every dose and keeps your last one marked, so you can see how you rotate sites over time.

## Every compound, explained.

Half-life, storage, and reported side effects in plain English, from Semaglutide and Tirzepatide to BPC-157. Reference material, not recommendations.

## Never lose a dose.

Every logged dose, site, and amount on one calendar you can scroll back through, next to the vials you have on hand.

## The rest of the kit.

### Protocols & reminders

Daily, weekly, or every-N-days rhythms, with reminders that follow the schedule you set.

### Vial inventory

Each vial's mg, the water you mixed in, and the day you mixed it.

### Streaks

Consistency, tracked. Streaks reward showing up, never outcomes.

### CSV export

Your dose, mix, and weight history as a spreadsheet, sent wherever you choose.

### A scope-limited assistant

Answers educational questions about compounds and logistics. It will not suggest doses or protocols, by design.

## Private by architecture.

The tracker has no backend. What we never receive cannot leak.

### What stays on the device

- **Account**: None. There is no sign-up, no email field, no password to reuse.
- **Dose logs**: Stored on your iPhone, nowhere else. Delete the app and they are gone.

### What leaves it

- **Assistant & scanner**: The two features that send your content off the device. Questions and label photos go to an EU-hosted endpoint with a random device id, never an account. You are asked before the first one.
- **Your logs as a product**: Never sold, never shared. AppsFlyer, the one ad SDK on board, gets install and purchase events and nothing from your logs.

## Not sure it fits your routine?

A 60-second fit check maps your schedule into a week-one plan: dose days, reminders, streaks. It runs in your browser and your answers stay there.

## Questions, answered plainly.

**Does Peptyn tell me what dose to take?**

No. Peptyn never suggests doses, compounds, or protocols. It tracks the plan you and your healthcare provider decided on, and its library is educational reference only.

**Where is my data stored?**

On your iPhone. There is no account and no Peptyn server holding your logs. Assistant questions and vial photos go to an EU-hosted endpoint with a random device id, and are not stored by us.

**Which GLP-1s and peptides does it cover?**

The library covers common GLP-1s such as Semaglutide and Tirzepatide alongside widely discussed research peptides such as BPC-157, each with half-life, storage, and reported side effect notes in plain English.

**Is Peptyn medical advice or a medical device?**

Neither. Peptyn is an educational tracking tool for adults 18 and over. It does not diagnose, treat, or advise. Talk to a licensed healthcare provider before making any decision about your health.
