Privacy Policy — KidStickers & TogetherStickers for iPhone and iPad

Last updated: September 24, 2026

KidStickers and TogetherStickers ("the Apps") value your privacy. This policy explains how the iPhone and iPad Apps handle your data. The privacy policy for the KidStickers web version and Android app is available in Traditional Chinese.

Data we collect or use

  • iCloud CloudKit Private DB: Your sticker book data (child nicknames, stickers, rewards) is stored in a structured format in your iCloud Private Database. Only you can access it; the developer cannot view it.
  • iCloud CloudKit Shared DB: TogetherStickers supports iCloud sharing, allowing you to share sticker books with others. Shared data is also stored in a structured format. Only the share creator and invitees can view it; the developer cannot access it.
  • Push Notifications: Used for data sync notifications.
  • AI sticker story / summary (Apple Intelligence): When you choose to tap "AI sticker story / summary" in the App, the App passes that child's nickname, plus the date and note text of each sticker in the period you selected, to Apple's language model to generate a short text. No photos or avatars are included, and no data about your other children.
    • Starting with KidStickers 1.20.0 and TogetherStickers 1.15.0, on devices running iOS 27 or later that support Apple Intelligence, the App prefers Apple's Private Cloud Compute: the text above is sent from your device directly to Apple's servers for processing. It never passes through the developer; the developer does not receive and cannot access this content or the generated result. According to Apple, data sent to Private Cloud Compute is used only to fulfil that request and is not retained; for its privacy and security design, see Apple's official description.
    • When Private Cloud Compute is unavailable (for example, no network connection or the daily usage limit has been reached), and in earlier versions of the Apps, the on-device Apple Intelligence model is used instead and the data does not leave your device.
    • The feature runs once each time you tap it; if you do not use it, nothing is sent for this purpose. The generated text is only shown on screen and is not stored by the App unless you choose to share it.
  • Crash diagnostics (Firebase Crashlytics): If the App crashes, crash diagnostics (such as device model, OS and App version, the stack trace at the time of the crash, and a randomly generated installation identifier) are sent to Google's Firebase Crashlytics, solely to find and fix problems. We do not attach your sticker book content, child nicknames, or photos.
  • Usage statistics (Firebase Analytics, TogetherStickers 1.15.0 and earlier only): TogetherStickers 1.15.0 and earlier use Google's Firebase Analytics to collect non-identifying usage statistics (such as app opens and screen views, App version, device model, OS version, language and approximate region, and a randomly generated app-instance identifier) to understand how features are used. This does not include sticker book content, child nicknames, or photos; the App does not request tracking permission, so it does not obtain the advertising identifier (IDFA). Starting with TogetherStickers 1.15.1 this collection is disabled (it has always been disabled in KidStickers); once updated to 1.15.1 or later, the App no longer sends any usage statistics.

We do not

  • Create accounts or require sign-in.
  • Upload your personal content to developer-run servers; your data stays in your iCloud Private Database or shared databases you participate in.
  • Access photos you did not explicitly pick; selected images are cropped into a circle and compressed for storage.

Retention & Security

  • You may delete the App anytime; data remains in iCloud until you remove it via iCloud or within the App after reinstalling.
  • Transport and at-rest security are provided by Apple CloudKit. Your sticker book content is stored only in iCloud; apart from the AI feature (Apple) and the crash diagnostics and usage statistics (Google Firebase) described above, we do not send data to any other third-party servers.

Third-Party Services

  • Apple iCloud / CloudKit (private storage & sync)
  • Apple Intelligence (on-device model and Private Cloud Compute, for the AI sticker story / summary)
  • Google Firebase Crashlytics (crash diagnostics); Google Firebase Analytics (usage statistics, TogetherStickers 1.15.0 and earlier only). For how Firebase handles data, see Privacy and Security in Firebase.

Children's Privacy

The Apps are intended for family use. We do not ask children to submit personal identifying information. Parents should manage the device and iCloud account appropriately.
