This Privacy Policy explains how we collect, use, and protect your information.

Information We Collect

toilet (App)

• Anonymous Identifier: We use Firebase Authentication to generate an anonymous user ID. No personal login (email, phone, social account) is required.
• Game Data: Rating, win/loss record, and nickname are stored on our servers to enable online multiplayer features.
• Nickname: You may set a display name visible to other players during online matches. This is optional and can be changed at any time.
• Advertising Data: We use Google AdMob to display advertisements. AdMob may collect device identifiers and usage data for ad personalization.

TypingStream (web)

• Anonymous Identifier: When you open the results or the ranking, we use Firebase Authentication to generate an anonymous user ID. No personal login is required.
• Ranking Records: When you set a new personal best, your listener name and your record (score, typed keys, accuracy, typing speed, and the time of the record) are stored on our servers (Cloud Firestore) and shown publicly on the ranking. The listener name is optional; if you leave it empty, "名無しのリスナー" (Anonymous Listener) is used.
• Data Stored in Your Browser: Your listener name, settings (such as the last stage and sound), and personal bests are kept in your browser's local storage. They are not sent to us except as part of a ranking record.
