Privacy Policy

1. Game progress and preferences

The game stores progress and preferences on your device, including scores, coins, lives, unlocked items, companion progress, check-ins, language, sound, gameplay settings, and any Tuantuan codename you choose. The codename is used only on your device and is not uploaded to the public leaderboard. You can play as a guest without creating a separate account with us. We do not operate a separate player-account or game-save server for this version.

2. Google Play Games, cloud saves and global rankings

Google Play Games sign-in is optional. When signed in, Google may process your player identifier, profile name and image, authentication status and saved-game data. We use Play Games authentication to save or restore progress across compatible Android devices using the same account and, when you open the global rankings, to verify a single-use server authorization code.

The global Sweet Dream and Nightmare rankings are provided separately through a Cloudflare Worker and Cloudflare D1. After verification, the service creates a short-lived private leaderboard session. You may join the rankings or browse without joining. Scores are uploaded only after you choose to join.

A joined player's public row contains only a server-issued name such as Tuantuan #000001 and the highest score for each game mode. Your Play Games name, avatar, raw Player ID and locally chosen Tuantuan codename are not published or stored in the public leaderboard. The service stores a keyed, non-public digest derived from the Player ID, the sequential public number, consent and update timestamps, and the two highest scores. Play Integrity may process app-recognition and licensing signals to reduce automated abuse.

Cloud saves include gameplay progress and settings; purchase entitlements are restored separately through Google Play Billing. Our use of information received from Google APIs follows the Google API Services User Data Policy, including its Limited Use requirements. We do not sell your personal data or use your Play Games profile or saved-game data to target advertising.

3. Advertising and purchases

Versions with live advertising use Google AdMob for optional rewarded ads. Google's advertising SDK may process IP addresses, approximate location inferred from IP, device or advertising identifiers, app interactions and diagnostic information to deliver and measure ads, prevent fraud and maintain the service. Google User Messaging Platform manages advertising privacy choices where applicable. Available choices can be revisited through the game's Ad Privacy Choices entry when shown. Closed-test builds that use simulated reward animations do not request live ads through that flow.

Optional purchases use Google Play Billing. The game processes product identifiers, purchase tokens and purchase status to grant or restore an entitlement. Google handles payment information; we do not receive your card details.

Google services are governed by the Google Privacy Policy. Learn about Google advertising technologies.

4. Support and this website

If you email us, we receive your email address, message and any information you choose to include. The game's support email may prefill app version, distribution platform, device model, operating system, language and screen details. You can review or remove these details before sending. We use support messages to answer requests and investigate problems.

This website has no forms, advertising or analytics scripts added by us. The hosting provider may process normal connection information, such as IP address, requested page and browser information, to serve and secure the site.

5. Storage, sharing and deletion

Local saves remain until you clear the app's data or uninstall it. Deleting local data does not necessarily remove a Google cloud save; signing in again may restore progress. Use Google Play Games settings to manage or delete Play Games data. In the game, use Settings → Leave leaderboard and delete cloud leaderboard data to remove both mode scores, leaderboard membership and active leaderboard sessions. A deleted public number is not reused; only the non-personal aggregate sequence state remains. This action does not delete local saves or Google Play cloud saves.

Google processes Play Games and Play Integrity information under its privacy policy. Cloudflare processes leaderboard requests and database records as a service provider; its global infrastructure may process network, security and service data in multiple locations. We retain support correspondence only as long as needed to address the request and meet applicable obligations. Contact us to request access, correction or deletion of information we hold. We may need enough information to verify and locate your request. Service connections use the providers' security protections, but no system can be guaranteed completely secure.

6. Children and policy changes

We do not knowingly request personal information from children through support. If you believe a child has sent us personal information, contact us so we can review and delete it as appropriate. Families should follow applicable age requirements and Google's account and parental-control settings.

We will update this page when our practices change and provide additional notice where required.
