Privacy Policy

This policy describes what 词语大冒险 · Word Adventure actually collects, which is very little. It is written PDPA-first for Singapore and is suitable for a mixed-age audience.

Playing the game

• Your progress — stars, XP, mastered words, settings — is stored in your browser's local storage on your own device. It is not sent to us unless you sign in (below).
• The app contains no analytics, no advertising and no tracking SDKs.
• If the app crashes, it sends us a short report so the fault can be fixed: the error message, where in the code it happened, the page address, your browser version and the country your request came from. It contains none of your progress and nothing that identifies you.
• Listening features use your browser's built-in text-to-speech. Audio is generated on your device.
• The app loads fonts and character stroke data from content delivery networks (Google Fonts, jsDelivr). Those requests carry the standard technical data any web request does, such as your IP address, handled under those providers' policies.

If you sign in with Google

• Signing in is optional. When you do, your progress — lessons, stars, words, characters practised, papers sat — is stored under your account on Google's Firebase servers so it follows you to your other devices, and it is merged with what each device already holds. Your handwriting strokes, settings and preferences stay on the device.
• Firebase Authentication keeps the email address and name of the Google account you signed in with. We do not use them for anything but recognising you, and we do not share them.
• Deleting your account (see the delete-account page) removes the stored progress with it.

If you subscribe

• Subscribing requires an account so your unlock can follow you across devices. The account is pseudonymous by default: a generated identifier, your subscription plan and its renewal date.
• Card details are entered on the payment provider's hosted page (Airwallex) or in Google Play. We do not receive or store card numbers.

Children

The free game collects no personal data, so a child can play it without providing any. Subscriptions are intended to be purchased by an adult.

Your choices

Clearing your browser's site data erases everything stored on the device. To delete a subscription account, see Deleting Your Account. For any other question about data, write to [email protected].
