The app

Peptide Trail Guide stores everything you enter — compounds, vials, doses, injection sites, metrics, photos and notes — only on your device. We do not run servers that receive this data, and the app has no account system.

Backups you export manually are files you control. Where you save or share them is up to you.

If you turn on encrypted backup, an encrypted backup file is saved to your own iCloud Drive or Google Drive account. It is encrypted on your device with a passphrase you choose before it is uploaded. We never receive this file and cannot read it. You can turn encrypted backup off and delete the backup file at any time.

Subscriptions are processed by Apple or Google. We use RevenueCat to check subscription status; it receives an anonymous app user ID and purchase receipts, never your health data.

The app contains no advertising and no analytics or tracking SDKs.

This website

This site sets no cookies. To see which pages and features are useful, it collects anonymous, cookieless usage statistics with Umami Cloud. We see only aggregate counts: page views (without URL query strings), referring sites, browser, operating system, device type and approximate location (country, region and city), plus counts of a few feature interactions — library searches (whether a search happened and a rough length, never the text), library filter choices, vial-size selections, “Open in calculator” clicks, calculator use (mg or IU only, never the figures you enter), clicks on the “Browse the library” and “Get the app” buttons, and clicks on source links.

Umami does not use cookies or collect personal data, and does not track you across other websites. Your IP address is used only briefly to estimate location and to compute a one-way, periodically rotated anonymous visitor ID; Umami does not store the IP address itself. Nothing you type into the calculator or the library search leaves your browser.

The site is hosted on GitHub Pages; GitHub may log visitor IP addresses for security purposes under its own privacy statement.

Children

Peptide Trail Guide is not directed at children under 17.
