The provider named above is the controller within the meaning of the GDPR and other national data-protection laws. LiftNerd is designed so that your training data stays primarily on your device. This Privacy Policy describes what data the app processes.

1. Locally stored data

Workouts, exercises, training plans, your profile (optional name, date of birth, gender, body weight), and settings are stored exclusively in your device's local storage (localStorage). This data does not leave your device unless you enable iCloud Sync (see section 3) or manually export it.

2. Apple Health (optional)

If you allow access to Apple Health, the app can read your body weight from Apple Health and write completed strength workouts (duration, estimated calories) to Apple Health. If you also turn on “Sleep & HRV”, the app reads sleep duration, heart rate variability (HRV) and resting heart rate from the past weeks and uses them to adjust the recovery battery. The app processes this health data only on your device. It is not transferred via iCloud Sync and is not shared with anyone. All access is granted only with your explicit permission and can be revoked at any time in iOS Settings.

3. iCloud Sync (optional, Pro feature)

If you enable iCloud Sync, the app synchronizes your workouts, exercises, training plans, profile, and volume landmarks via Apple's CloudKit service into your private iCloud database. Activation happens only with your explicit consent (tapping "Enable now" in the dialog or the toggle in Settings).

• Legal basis: Art. 9(2)(a) GDPR (explicit consent for health-related data).
• Storage location: Your personal iCloud under your Apple ID. The provider of LiftNerd has no access to your synced data.
• Processor: Apple Inc. (see Apple's iCloud privacy notices).
• Data transferred: All data listed in section 1, except app-local preferences such as language, weight unit, and gym mode, which stay on the device.
• Disable: You can turn iCloud Sync off any time under You › iCloud Sync. Future changes then stop syncing. Data already stored in iCloud remains until you delete it on a device or clear your iCloud storage via iOS Settings.
• Automatic deactivation: If your Pro subscription lapses or the trial ends, iCloud Sync is automatically disabled.
• Withdrawal: You can withdraw your consent at any time with effect for the future by disabling sync.

4. Audio cues during rest

On request, the app announces audio cues during the rest timer (e.g. "30 seconds left" or "Go! Next set: 80 kilos, 8 reps"). Speech is generated entirely on-device using Apple system facilities (AVSpeechSynthesizer in the native build, Web Speech API in the browser preview). No text is transmitted to external servers. To allow announcements while the screen is locked or the app is in the background, the app declares the background-audio capability (UIBackgroundModes: audio) — there is no continuous microphone recording or processing. The mode (off / end-only / full) is set under You › Rest & reminders.

5. Strength standards

The age-based strength standards are computed entirely on your device using formulas and factors bundled with the app. No server request is made; no data is transmitted.

6. In-app purchases

Subscriptions are processed via Apple StoreKit. The app only receives the transaction status — no payment data, credit card data, or Apple ID information.

7. Analytics and advertising

The app uses no analytics tools, no tracking, no advertising, and no third-party SDKs for data collection.

8. Data export and deletion

You can export your data as a JSON file at any time under You › Export & import, and reset all workouts. When you uninstall the app, all local data is automatically deleted. If iCloud Sync was active, the data remains in your iCloud until you remove it there.

9. This website (liftnerd.app)

The following applies in addition to the app-related sections above and concerns only your visit to this website.

No third-party requests. All assets used by this website (fonts, stylesheets, images, scripts) are hosted on the same server and delivered directly from liftnerd.app. There are no calls to external CDNs, font services, analytics providers, or social-media platforms. Your IP address is therefore not transmitted to any third party simply by loading this page.

Server logs. When you access this website, the hosting provider's web server records technical data in access logs: IP address, date and time, requested resource, referrer, and user-agent (browser and operating system). This information is processed for IT security, stable operation, and prevention of abuse. Legal basis: Art. 6(1)(f) GDPR (legitimate interest). Retention: typically 30 days, then automatic deletion or anonymisation.

No cookies, no tracking, no analytics. This website sets no cookies, uses no tracking, no analytics, no advertising, no social-media plug-ins, and no contact or newsletter forms. For inquiries, please use the email address below.

10. Your rights

You have the rights set out in Art. 15 et seq. GDPR: access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20), and objection (Art. 21). Because LiftNerd processes your training data only on your device or — with sync enabled — in your personal iCloud, and the provider has no access to it, you can exercise these rights directly yourself: view, export, or delete data in the app; disable sync or remove iCloud data via iOS Settings. Any consent you have given (e.g. for iCloud Sync or Apple Health) can be withdrawn at any time with effect for the future.

You also have the right to lodge a complaint with a data-protection supervisory authority. Authority competent for the provider's seat: Bavarian State Office for Data Protection Supervision (BayLDA), Promenade 18, 91522 Ansbach, Germany, www.lda.bayern.de.
