たいむスタンプ is an Apple Watch timestamp recorder with an iPhone companion app. This privacy policy describes how たいむスタンプ handles data in the current app implementation.
たいむスタンプ does not collect personal data. Timestamp sessions, recorded times, session names, and memos are stored locally on the user's devices. The app does not send this data to an external server.
たいむスタンプ stores app data locally using device storage such as UserDefaults and app-local files.

たいむスタンプ does not include third-party analytics SDKs, advertising SDKs, tracking SDKs, or third-party login SDKs. たいむスタンプ does not track users across apps or websites.
たいむスタンプ does not require account creation, sign in, subscriptions, or in-app purchases.
