Privacy Policy

1. Who we are

LiftCore ("LiftCore," "we," "our") is a fitness logbook for iOS and Android. This Privacy Policy describes how the LiftCore mobile app and liftcore.app handle information.

Privacy questions: privacy@liftcore.app.

2. The short version

• Your training data stays on your device. Workouts, programs, templates, body weight entries, and preferences are stored locally in LiftCore v1.
• Emails are purpose-limited. If you email support, email privacy, or use the launch-link mailto, we receive your email address and message only for that request.
• Health data flows in only. If you grant permission, we read steps, sleep, and body weight from Apple Health or Health Connect. We don't write back, and we don't transmit that data anywhere.
• No advertising trackers. LiftCore contains no third-party advertising SDKs and does not engage in cross-app or cross-site tracking.
• Crash reports only. Anonymous crash reports help us fix bugs. They never contain your workouts, health data, or identifiers tied to you.
• You can leave at any time. Export your data as CSV. Uninstall the app to permanently delete every record from your device.

3. Information stored on your device

The following data is created and stored locally on your device, in the platform's standard storage (SQLite for structured data, SecureStore for preferences and keys). It is not transmitted to LiftCore or any third party.

• Workout logs — exercises, sets, reps, weight, RPE/RIR, notes, rest times, timestamps.
• Programs, templates, training blocks, and block history.
• Body weight entries you enter manually, plus your unit and preference settings (e.g. default rest, units, theme).
• An anonymous per-device identifier generated on first launch. It is not linked to your name, email, phone, or any external account.

4. Apple HealthKit (iOS)

If you grant LiftCore permission via the iOS Health permission sheet, LiftCore reads the following data from Apple Health to display trends and context inside the app:

• Daily step count
• Sleep sessions
• Body weight entries

HealthKit data is read-only. LiftCore does not write to Apple Health and does not modify your Health data. HealthKit data is processed on your device only and is never transmitted to LiftCore or any third party.

You can revoke HealthKit access at any time in iOS Settings → Privacy & Security → Health → LiftCore.

5. Health Connect (Android)

On Android, LiftCore integrates with Health Connect using the same principles as our HealthKit integration. With your explicit permission, LiftCore reads:

• Steps
• Sleep
• Weight

Health Connect data is read-only, processed on-device, and never transmitted off-device. You can revoke access at any time from Health Connect's settings.

6. Crash reporting (Sentry)

LiftCore uses Sentry to receive anonymous crash and error reports so we can fix bugs. Reports include technical context such as:

• Stack traces and the file/line where the error occurred
• Device model and operating system version
• App version and build number
• A randomly generated install identifier (not tied to you)

Crash reports do not include your workouts, programs, body weight, HealthKit/Health Connect data, name, email, phone number, IP-based location, or any other personally identifying information. Personally identifying scopes (PII fields, request bodies, breadcrumbs containing user input) are stripped before transmission.

7. Emails and launch list

If you email us for support, email us about privacy, or use the launch-link mailto on this site, your email client sends your email address and message to LiftCore. We use that information only to reply to your request or send the launch link you asked for. We do not sell it, add it to advertising audiences, or link it to your on-device training history.

You can ask us to delete support, privacy, or launch-list emails by writing to privacy@liftcore.app.

8. App Tracking Transparency (iOS)

LiftCore does not track you across apps or websites and does not present the App Tracking Transparency prompt. Our iOS privacy manifest (PrivacyInfo.xcprivacy) declares no tracking domains and no collected data types.

9. Data we do NOT collect

To be explicit, the LiftCore app does not collect or store on any LiftCore server:

• Your name, phone number, or postal address
• Your workouts, programs, sets, reps, weights, or notes
• Your HealthKit or Health Connect data
• Your photos, contacts, or location
• Advertising identifiers (IDFA / GAID)
• Account credentials of any kind

10. Your controls

• Export. Export your full training history as CSV from Settings → Data → Export at any time.
• Delete. Use Settings → Data → Clear all data to wipe LiftCore's local database. Uninstalling the app removes all locally stored data, including the per-device identifier.
• Health permissions. Revoke HealthKit / Health Connect access at any time in your OS settings. LiftCore will detect the change on next launch.
• Crash reporting. If you do not want LiftCore to send anonymous crash reports, contact privacy@liftcore.app and we will document the opt-out steps for your version.

11. Children

LiftCore is not directed to children under 13 and we do not knowingly collect data from children under 13. The app is rated 4+ on the App Store.

12. Security

Because LiftCore v1 keeps your training data on your device, the main defenses for your data are your device's lock screen, OS-level encryption, and your device's backup settings. We recommend keeping your device passcode/Face ID/Touch ID enabled and your OS up to date.

13. International users

Because LiftCore v1 does not transmit your training or health data off your device, no international data transfer of that data takes place. Anonymous crash reports may be processed by Sentry on infrastructure located in the United States and the European Union.

14. Changes to this policy

We may update this policy as the product evolves — for example, when we ship new integrations or change how crash reporting works. Material changes will be reflected here with an updated effective date. Continued use of LiftCore after the effective date constitutes acceptance of the revised policy.
