[Why Choose Us] Your private thoughts should never be stored on someone else's servers. In an era of frequent data breaches, we built a diary App that goes against the trend: • True Offline: No network permissions required. We do not request access to your location, contacts, or photos. Even the developers cannot access your words. • True Local Encryption: Supports Face ID, Touch ID, and password triple lock screen. Encryption protection helps reduce privacy risks if your phone is lost. • True Data Ownership: All diaries are stored only on your device. Support one-click export of encrypted PDFs, giving you full control over device switching and backups. [More Than Safe, A Recording Partner That Understands You] • Immersive Timeline: Say goodbye to cluttered lists and review your past like flipping through a life album. • Multimedia Diary: Each entry supports multiple images, giving your memories visuals and context. • Calendar Heatmap: See your recording frequency at a glance and fight forgetfulness with persistence. • Gentle Reminders: Customize your writing time. No interruptions, no pressure, only appearing when you need it. [Our Firmest Privacy Commitment] • Zero Network Requests: Verifiable anytime in settings. Absolutely no background uploads. • Zero Third-Party SDKs: No ad tracking, no data analytics, no social logins. • Your Data Belongs to You Forever: Even if the App is removed from the store, exported PDFs remain readable permanently. • Important Notice: Due to pure local storage, uninstalling the App will erase all data. Please regularly use the Export PDF feature to back up precious memories. Your data should be managed by you alone. [To You, Seeking a Place of Peace] We do not chase user numbers. We only wish to be a trusted sanctuary for the few. If you are tired of cloud sync anxiety, pop-up ads, and lengthy privacy policies, welcome back to this quiet corner that belongs only to you.
