EEA and UK privacy requests (GDPR / UK GDPR)
Where the GDPR or UK GDPR applies, email the address above to ask for access, erasure, a portable copy, rectification, or to object to legitimate-interest processing, or to withdraw consent. You may also complain to your supervisory authority. Most Lvji data is only on your phone: delete an entry, export a local backup, clear storage, or uninstall. We do not hold a server account to export. Cloud calorie estimate is optional, off until you agree, and never an unlock gate. Turn it off in diet settings to stop new meal-thumbnail uploads.
EU Article 27 representative: not appointed (TBD). No Union representative has been designated, so this page does not name one. A UK representative is also not appointed (TBD). Contact the controller at the email above. Details are in the privacy policy.
FAQ
- Can Lvji lock apps on iPhone? Yes. After you allow Screen Time and confirm with Face ID or your passcode, Lvji shields the apps you selected until today’s contract is done. iPad uses the same Screen Time shield. Lvji does not read messages or other apps’ content.
- Is camera video saved? No. Jump rope and pose counting use live frames in memory only. They are not saved to Photos or uploaded.
- Are meal photos uploaded? Not unless you turn on cloud calorie estimate and agree in the app. It is off by default. A downsized thumbnail and the meal label may then go to a Cloudflare Worker, which forwards the thumbnail to Alibaba Cloud DashScope Qwen-VL (or another vision endpoint if that Worker is reconfigured) and does not store the image. The result is a reference only. You can turn it off anytime. It never unlocks or blocks apps.
- What is free? One sport a day, jump rope or walking, and app lock. Lvji Pro adds push-ups, sit-ups, squats, plank, and hula hoop, and more than one sport in the same day. In the United States, Pro is US $2.99 per month with a 7-day free trial. The store shows the local price before you subscribe. The store product id is
reppy_pro_monthly; the name you see is Lvji Pro. - How do I replay onboarding? Settings → About & help → Replay onboarding.
- Can I restore progress on a new iPhone? On iPhone and iPad, Settings includes iCloud backup when you are signed into iCloud. Use Restore to bring back the contract, learning progress, reminders, and lock screen. Choose the locked apps again on that device. If iCloud is off or unavailable, use Local backup to export or import a JSON file. Android does not use iCloud.
- What does the Android Accessibility service do? Only if you turn it on, after the app explains it. It reads the foreground app’s package name on the device and sends you home when a chosen app is locked. In system settings the service is labeled 运动解锁. You can turn it off there at any time.
- Lvji Pro billing — Handled by Apple or Google. Use Restore Purchases in the app, or the store’s subscription settings.
