Privacy

Bạch Đằng does not collect, store on any server, or share any of your data.

Data on your device

Your current playthrough, unlocked history notebook cards, endings, achievements and settings are saved on your device only, so you can continue playing. They never leave your device. Deleting the app, or choosing “Delete all saved data” in Settings, removes them.

Achievements

If you are signed in to Game Center (iPhone, iPad) or Google Play Games (Android), the game tells that service when you unlock an achievement. Apple or Google handle this under their own privacy policies. The game does not read your friends list, your name or any other account information.

None of these

No ads, no analytics or tracking, no accounts, no in-app purchases, and no access to your photos, location, microphone or contacts.

Children

The game is rated 12+ because it shows historical war violence. It collects no data from anyone, including children.
