InjectBuddy for iOS: Privacy Policy

This policy covers the InjectBuddy for iOS app (bundle ID com.injectbuddy.app). The app is a tracker for your own doses, protocols, cycles and blood tests. It is not medical advice. The website calculators have their own policy at /privacy/.

Sign-in is optional

You can use the app without an account. Everything you enter is then saved only on your device. If you sign in with email, Google or Sign in with Apple, your data is stored on the InjectBuddy server (Supabase) so it syncs across your devices.

What is synced when you sign in

• Your doses, protocols, cycles, blood tests, body measurements and progress.
• Your profile, including your name, and your avatar photo.
• Your timezone and reminder preferences, and your subscription status.
• Support chat messages and suggestion posts (with your display name), which are sent to injectbuddy.com.

Data we collect

When you are signed in, the app collects the following. This data is linked to your account and is used only to run the app and sync it.

• Health — dose logs, protocols, cycles, blood tests and body measurements.
• Email address — used to sign in.
• Name — entered at sign-up, or provided by Apple.
• User ID — your account identifier.
• Photos — your avatar photo, if you choose one.
• User content — support chat messages and suggestion posts.
• Purchases — your subscription and purchase status.
• Crash data — error reports, described below.

No analytics and no tracking

The app does not include analytics, advertising identifiers or session recording, and it does not track you across other apps or websites. Your data is never used for tracking. The InjectBuddy website is separate: it uses the analytics described in its own policy at /privacy/.

On your device

• Reminders — the app sends local dose reminders using notification permission you grant.
• Calendar — if you allow calendar access, the app adds your scheduled doses to your calendar on this device.
• Photos — photo access is used only to choose a profile picture.

Crash reporting

If the app crashes or hits an error, it sends an error report to Sentry so we can fix the problem. A report contains the error type, where in the code it happened, the app version, your device model and system version, and your user ID if you are signed in. It never contains your doses, protocols, blood tests, profile or email address.

Service providers

• Sign in with Apple — optional sign-in.
• Supabase — stores account data for signed-in users.
• RevenueCat — processes your subscription status and user ID, so your access works across the app and the website.
• Sentry — crash reports, as described above.
• Anthropic (Claude) — only if you use the body-fat estimate or the blood-test reader on injectbuddy.com. The photo or file you choose is sent to Anthropic's API (overseas, United States) to produce the result.
• Telegram — support chat messages, with your display name, are forwarded to our support inbox in Telegram (overseas).
• Resend — sends some of our emails, such as reminders to confirm your email address.
• Apple, Google and Stripe — handle payments. Purchases in the app go through Apple or Google; purchases on the website go through Stripe. InjectBuddy does not receive or store your card details.

These providers handle data under their own privacy policies.

Access, export and deletion

When you delete your account we also ask Stripe, RevenueCat and Telegram to delete the copies they hold for us. Stripe may keep payment and invoice records it must hold for tax and legal reasons, RevenueCat may keep anonymised purchase records, and Telegram messages older than 48 hours may remain in our support inbox until we clear them by hand. We keep a private, add-only log recording the date, your account ID and the action when an account is exported or deleted; it never holds the content of your data.

• Signed out: deleting the app, or clearing its data, removes everything you entered on the device.
• Signed in: in the app, go to Settings and tap Download my data to export your data.
• Account deletion: in the app, go to Settings and tap Delete account. This deletes your account and its data from our server, and it cannot be undone.
