隱私權政策
生效日期：2026 年 9 月 25 日
簡單說
Attacca 不收集、不傳送任何個人資料。你輸入的一切都只存在你的裝置上。
App 會存什麼
你建立的曲目、段落、速度、拍號、重音與延長記號，會存在裝置上 App 專屬的本機資料庫。這些資料會隨裝置本身的備份（iCloud 或 Google 帳戶備份）一起備份，但 Attacca 本身不會把它們傳送到任何地方。
我們不收集的資料
Attacca 沒有帳號、沒有登入、沒有廣告、沒有分析或當機回報工具，也沒有自己的網路連線。我們不收集姓名、電子郵件、位置、使用紀錄、裝置識別碼，或任何能識別你或你裝置的資訊。
權限
Attacca 只使用播放聲音所需的音訊輸出，不要求麥克風、相機、聯絡人、位置或其他權限。
第三方
目前版本沒有任何第三方服務。若日後的版本加入 App 內購買，付款將由 Apple 或 Google 的購買系統處理；該版本上架前，本政策會先更新並寫明實際使用的服務。
刪除資料
刪除 App 就會立即刪除它存在裝置上的所有資料。裝置以外沒有任何資料需要另外刪除。
兒童
Attacca 是一般用途的音樂工具，沒有聊天或社群功能，也不向任何人（包括兒童）收集資料。
政策變更
本政策若有實質變更，會更新上方的生效日期，並同步更新 App Store 與 Google Play 上的隱私權標示。

Privacy Policy
Effective: September 25, 2026
The short version
Attacca does not collect or transmit any personal data. Everything you enter stays on your device.
What the app stores
The pieces, sections, tempos, time signatures, accents and fermatas you create are saved to a local database private to the app on your device. They are included in your device's own backup (iCloud or Google Account backup), but Attacca itself never sends them anywhere.
Data we do not collect
Attacca has no account, no sign-in, no ads, no analytics or crash-reporting tools, and no network connection of its own. We do not collect names, email addresses, location, usage data, device identifiers, or anything else that could identify you or your device.
Permissions
Attacca uses only the audio output it needs to play the click. It does not request the microphone, camera, contacts, location, or any other permission.
Third parties
This version uses no third-party services. If a future version adds in-app purchases, payment will be handled by Apple's or Google's own purchase system, and this policy will be updated to name the services involved before that version is released.
Deleting your data
Uninstalling the app immediately deletes everything it stored on your device. Nothing exists anywhere else to delete.
Children
Attacca is a general-audience music tool with no chat or social features, and it collects no data from anyone, including children.
Changes to this policy
If this policy changes materially, the effective date above will be updated, along with the privacy labels on the App Store and Google Play.
