Privacy policy

Playing and keeping your progress
TZ100 uses cookies, browser storage and server records to support sign-in, guest identity, language preferences, game saves, scores and security.
Site visit statistics
To understand site usage, TZ100 uses a first-party visitor cookie valid for one year to record public-page visit times, sign-in status and username when signed in, visit counts, referring pages, device, operating system and browser. IP addresses are resolved locally to an approximate country and, in China, province. Visit details do not store raw IP addresses; referrer queries and fragments are removed. Details are available only to administrators. Continuous browsing is one visit; more than 30 minutes without activity starts another. Clearing cookies or changing devices resets the browser visit count.
Google One Tap
When you are signed out, the home and category pages may load Google sign-in services and show an account chooser provided by Google or your browser. Only after you choose an account and confirm does TZ100 receive a sign-in credential and basic account information (email, name and profile picture). We do not automatically choose an account or read your Google password.
Quick sign-in is used to sign in and sync guest progress. You can dismiss the prompt and keep playing as a guest or choose another sign-in method. The prompt is attempted only once per tab session.
Google AdSense advertising
tz100.com uses Google AdSense advertising. We display ads through Google and its advertising partners to support site operations and free games.
Third-party providers, including Google, may place or read cookies in your browser and use web beacons, IP addresses, device or browser identifiers, and information about pages visited, ad impressions and interactions. They use this information to deliver ads, control frequency, measure performance and prevent fraud and abuse.
Where your settings and applicable consent choices allow, Google and its partners may use advertising cookies to personalize ads based on your previous visits to TZ100 and/or other websites. Turning off ad personalization does not turn off all ads. Non-personalized ads may still use cookies or other identifiers for frequency control, aggregate reporting or fraud prevention.

You can manage or delete cookies through your browser. Clearing all site data may affect sign-in, guest identity and local progress.
Ad personalization and the use of advertising cookies are subject to applicable requirements in your region and your consent choices. If an advertising consent prompt or privacy settings control is displayed, you can use it to view provider information and manage or withdraw your choices. This privacy policy does not itself mean that you have consented to advertising cookies.
