慳啲（SaveDee，以下簡稱「本應用程式」）由開發者個人營運，幫香港用戶比較超市產品價格。我哋以最少必要原則收集資料，唔需要你註冊帳戶、唔需要電郵地址、亦唔會追蹤你嘅位置。
SaveDee is operated by an independent developer. We collect the minimum data required to operate the service — no account, no email, no location tracking.
為咗讓你嘅收藏、價格通知、用戶分享等功能正常運作，我哋會喺伺服器儲存：
To operate your watchlist, alerts, and community submissions, the server stores: anonymous device UUID; your watchlist and alert settings; prices and photos you voluntarily submit (with EXIF stripped); and your verification votes.
We do not collect: names, emails, phone numbers, GPS, contacts, photo library beyond your explicit uploads, IDFA, or any third-party analytics.
上載嘅價格相片喺裝置端先壓縮（最長邊 1600 px，約 1 MB JPEG），重新編碼以移除所有 EXIF 中繼資料（GPS、拍攝時間、裝置型號）。上載後嘅檔案以隨機 UUID 命名，URL 無法被列舉。相片只用於價格驗證，唔會出售或轉移俾任何第三方。
Photos are compressed on-device, re-encoded to strip all EXIF (including GPS), and stored with random UUID filenames so URLs cannot be enumerated. Used only for price verification — never sold or transferred to third parties.
用戶提交嘅價格 7 日後自動過期。違反使用條款嘅內容（隱藏狀態）會保留作審計用途。收藏清單一直保留直至你親自刪除或卸載應用程式。
User-submitted prices auto-expire after 7 days. Content hidden under our Terms is retained for audit. Watchlists persist until deleted by you.
價格通知用 iOS 本地通知方式產生，唔需要 server push（APNs）。監察邏輯喺裝置上運行，伺服器只會喺你查詢時返回最新價格。
Price alerts use iOS local notifications, not APNs. Matching runs entirely on-device.
你隨時可以：刪除自己上載嘅價格、停用通知、清除收藏、或要求刪除所有連住你 Device ID 嘅伺服器資料。如要徹底刪除，請電郵至文末聯絡地址，並引用 Settings 頁面顯示嘅 Device ID。我哋會喺 7 個工作日內處理。
You can: delete your submissions, disable alerts, clear watchlist, or request full server-side deletion. Email us your Device ID (shown under Settings) — processed within 7 business days.
本應用程式並非針對 13 歲以下兒童設計，亦唔會主動收集兒童資料。
Not directed at children under 13; we do not knowingly collect data from children.
本政策可能因功能變更或法律要求而修訂。重要修訂會喺應用程式內顯示通告。
Material changes will be notified in-app.
