PeptideCalc

Privacy Policy

Last updated: 2 September 2026

Information we collect

None. We do not collect, transmit, sell, or share any personal information. The app has no backend, so there is nowhere for your data to be sent.

Data stored on your device

To make the app work, PeptideCalc saves the following locally on your iPhone. This data never leaves your device unless you choose to include it in your own iCloud or iTunes device backup, or export it yourself.

• Vials — the peptide name you type, vial strength, water volume, concentration, default dose, syringe type, status, reconstitution and expiry dates, and any notes you add.
• Dose log — the date and time of each dose you record, the peptide name, dose, volume, syringe units, the injection site you tap on the body map, and your note.
• Reminders — the schedule you set for each vial: days or interval, time of day, and how many follow-up nudges you want.
• Your settings — default dose unit, default syringe, default expiry period, and appearance (system, light, or dark).

There are no diagnostic counters, crash reporters, or event logs of any kind. Deleting the app removes all of this data permanently.

Health information

The doses and injection sites you record are health-related and we treat them accordingly: they are written only to the app's private storage on your device, they are never transmitted to us or to anyone else, and they are never used for advertising or marketing. PeptideCalc does not request access to HealthKit, and it does not read or write anything in the Health app.

Notifications

Dose reminders are local notifications scheduled by the app on your device. We do not use push notifications, and no server is involved, so we never learn when or whether you receive one. If you use the Log dose button on a reminder, the entry is written straight to your device's local log.

Exports and sharing

The PDF and CSV exports of your dose history are generated on your device. Nothing is uploaded. The file goes only where you send it through the iOS share sheet — for example to Files, Mail, or a messaging app — and once you share it, the receiving app or service handles it under its own privacy policy.

Purchases and ratings

PeptideCalc is free. There are no in-app purchases, no subscriptions, and no ads. The app may occasionally ask you to rate it; that prompt is presented and handled entirely by Apple, and we receive no personal information from it. Apple's handling of App Store activity is covered by Apple's Privacy Policy.

Children's privacy

PeptideCalc is intended for adults and is not directed at children under 13. Because the app collects no personal data, it does not knowingly collect information from children.

Third parties

PeptideCalc includes no third-party analytics, advertising, tracking, or attribution SDKs, and no third-party libraries of any kind. Aside from Apple's own App Store handling described above, no third party receives any data from this app.

Your rights

Because all data is stored locally and we hold none of it, you have complete control: you can edit or delete any vial or log entry inside the app, export your history at any time, or delete the app to erase everything. There is no data for us to access, export, or delete on your behalf.

Not medical advice

PeptideCalc is a calculator and record-keeping tool. It performs arithmetic on numbers you enter and stores what you choose to log; it never suggests doses, schedules, or protocols. Always verify your numbers and consult a licensed healthcare provider before injecting.

Changes to this policy

If this policy changes, we'll update this page and revise the date above.
