Privacy Policy

What we collect

Nothing. Private Workout Logger has no analytics, no advertising SDKs, no crash reporting that leaves the device, and no third-party trackers. We do not collect a name, an email, an advertising identifier, or any usage data. There is no sign-up and no login because there is no account.

Where your data lives

Everything you log — workouts, sets, exercises, notes, and settings — is stored in a single on-device SQLite database. That database lives in a private App Group container on your iPhone (group.com.lukewalton.workoutchatlog), which lets the app and its Home Screen widget read the same file. It is never uploaded anywhere by the app.

Standard iOS device backups (iCloud Backup or an encrypted local backup) may include the app’s container, the same as any other app’s local data. That backup is governed by Apple’s privacy terms and your device settings, not by us; we never transmit your log to our own servers because we don’t have any.

Apple Health (optional, opt-in)

If — and only if — you explicitly turn it on in Settings and grant permission, Private Workout Logger can:

• Read your most recent body weight, used only on-device to estimate calories.
• Write one workout summary per finished session to the Health app.

Health data is used only inside the app. It is never transmitted off the device, never used for advertising, and never written to iCloud by us. We never write an estimated or guessed value (such as a rough calorie estimate) into Health energy data. You can revoke Health access at any time in the iOS Settings app, and the rest of the app keeps working.

Camera and photos (optional, opt-in)

The Scan feature can read a workout written on paper by recognizing text in a photo, entirely on-device (Apple’s Vision framework). It runs only when you choose it. Importing a photo uses the out-of-process iOS picker, which needs no photo-library permission; using the camera instead asks for camera permission in context. Recognized text goes through the same confirm-before-save flow as typed input. No image or recognized text is transmitted anywhere.

Sharing is always your choice

When you tap an export or share action, you decide where the data goes (for example, the iOS share sheet). The app prepares that payload locally; it is sent only because you chose to send it.

What Private Workout Logger does not do

• No accounts, no servers, no cloud sync operated by us.
• No analytics, no telemetry, no advertising, no ad identifiers, no ATT prompt.
• No selling or sharing of data — there is no data leaving the device to sell.
• No medical, diagnostic, or coaching claims. Calorie and “feel” figures are honest, user-entered or clearly labeled estimates, not health advice.

Children’s privacy

The app collects no personal information from anyone, including children.

Changes
