SuiSui does not collect, store or transmit any personal data. Every day you record and every setting you change lives only on your own device — and in your device's own backups.
SuiSui needs no account. It contains no third-party analytics, attribution or advertising SDKs, and shows no ads.
SuiSui asks for notification permission only when you turn on a reminder for a particular day. Reminders are scheduled by the operating system on the device itself and never pass through a server: UNUserNotificationCenter on iOS and macOS, AlarmManager on Android and the Xiaomi build, and the system reminder agent (reminderAgentManager) on HarmonyOS.
The Xiaomi build's settings screen offers two shortcuts — "autostart management" and "battery saver policy" — which do nothing but open the system's own settings pages, where the decision is yours. SuiSui does not read the state of either setting and learns nothing from them.
SuiSui Pro is an in-app purchase made through the App Store (iOS, macOS), Google Play (Android), Huawei AppGallery (HarmonyOS) or the Xiaomi App Store (Xiaomi build). Payment is handled entirely by Apple, Google, Huawei or Xiaomi, and none of your payment information reaches us. The HarmonyOS build uses Huawei's in-app payment service (IAP Kit), where buying and restoring run through your Huawei account; the Xiaomi build uses Xiaomi's in-app purchase service, where buying and restoring run through your Xiaomi account and the sign-in flow is started by Xiaomi's SDK — SuiSui never touches your Xiaomi credentials. The iOS, iPadOS and macOS versions share a single Universal Purchase: buy it on one, then tap Restore Purchases on the others. Purchases made in different app stores are separate and do not carry across.
The iOS, macOS and Android versions all support home screen widgets (iOS adds Lock Screen widgets, macOS adds a menu bar item), and the HarmonyOS version offers 2×2 and 2×4 service cards. Everything they show is read from data stored on the device, and likewise never passes through a server.
"Save as Image" on the Mac opens the system save panel, and SuiSui writes that one share card only after you have picked a location yourself. Beyond that, SuiSui neither reads nor writes any of your files.
The HarmonyOS build declares network access, used solely by Huawei's in-app payment service to verify purchases and restores. The Xiaomi build likewise declares network access, used solely by Xiaomi's in-app purchase service for the same checks. SuiSui itself uploads none of your days, settings or usage data, and talks to no server apart from those payment checks.
The Android and Xiaomi builds also declare the "view network connection state" permission (ACCESS_NETWORK_STATE). It comes from the Jetpack library the home screen widgets are built on, and only lets the system decide when to run a scheduled widget refresh; it grants no ability to access the network, and SuiSui does not use it to transmit anything. It does not apply to the iOS and macOS versions.
This policy covers the iOS (iPhone and iPad), macOS, Android (Google Play), HarmonyOS (Huawei AppGallery) and Xiaomi (Xiaomi App Store) versions of SuiSui. All five handle data identically: stored on the device only, with no account, no ads and no third-party analytics or tracking SDKs. Each platform keeps its own data locally; nothing syncs between devices.
On first launch, the Xiaomi build presents this policy and asks you to accept it. Until you do, SuiSui initialises no third-party SDK and processes no data; if you decline, the app exits.
