Short version: Your puzzles, progress, collection and capsule results stay on your device. Prism has no account requirement, no advertising, and does not sell personal data. Apple and RevenueCat process purchase information only when needed to provide Prism Pro. Starting with version 1.6, Prism collects anonymous crash reports and anonymous usage statistics to improve the game — never linked to your identity and never used for tracking; usage statistics can be switched off in Settings.
簡要說明：題目、進度、收藏與轉蛋結果都保留在你的裝置上。Prism 不要求帳號、不顯示廣告，也不販售個人資料。只有在提供 Prism Pro 權限所需時，Apple 與 RevenueCat 才會處理購買資訊。自 1.6 版起，Prism 會收集匿名當機報告與匿名使用統計以改善遊戲——皆不連結你的身分、不用於追蹤；使用統計可隨時在「設定」中關閉。
Prism does not require an account and does not ask for your name, email, contacts, photos, or location. Your puzzle progress, statistics, streaks, and settings are stored only on your device and are never uploaded to us. The only data that ever leaves your device is described below: purchase entitlement for Prism Pro, anonymous crash reports, and anonymous usage statistics.
If you buy Prism Pro, the transaction is handled by Apple. We use RevenueCat to verify and manage your subscription entitlement. For this purpose a non-identifying app user ID and your purchase history are processed. This is used solely to deliver the features you paid for. It is not used to track you and is not linked to your identity. See Apple's and RevenueCat's privacy policies for details.
Capsules contain cosmetic board auras only and never improve puzzle performance. Tickets cannot be purchased, traded, gifted, redeemed for money, or transferred to another person. The odds are shown before every draw: Common 70%, Rare 25%, and Legendary 5%. Every capsule contains one item, duplicate protection applies within each rarity, and the tenth draw after nine Common results is guaranteed Rare or better.
If you turn on the optional daily reminder, Prism schedules local notifications on your device. No push server is involved and no data is sent to us.
To find and fix bugs, Prism sends anonymous crash and error reports using Sentry. A report contains technical details only — such as device model, OS version, app version, and the error's stack trace. Reports are not linked to your identity, are never used for advertising or tracking, and IP addresses are processed transiently for delivery only. See Sentry's privacy policy for details.
為了找出並修正錯誤，Prism 會透過 Sentry 傳送匿名的當機與錯誤報告，內容僅含技術資訊（裝置型號、系統版本、App 版本與錯誤堆疊），不連結你的身分，也不用於廣告或追蹤。
Prism uses Aptabase, a privacy-first analytics service, to count a small fixed list of anonymous events (for example "daily puzzle solved" or "paywall viewed"). These events contain no personal identifiers, no advertising IDs, and no device fingerprinting; they are not linked to your identity and are not used for tracking. You can turn this off at any time in Settings → Share anonymous usage statistics. See Aptabase's privacy policy for details.
Prism 使用注重隱私的 Aptabase 統計少量固定的匿名事件（例如「完成每日挑戰」「開啟付費頁」），不含個人識別碼、廣告 ID 或裝置指紋，不連結身分也不用於追蹤。你可以隨時在「設定 → 分享匿名使用統計」關閉。
Prism is not listed in the Kids category. Because it includes randomized cosmetic capsules, its App Store age-rating questionnaire declares Loot Boxes and the global rating is expected to be 9+. We do not knowingly request personal information from children.
You can erase all local data at any time in Settings → Clear local data. Deleting the app also removes its on-device data.
If this policy changes, we will update this page and the "last updated" date above.
