Privacy Policy私隱政策
Privacy Policy
Effective date: 29 September 2026
In short: Knob Sketch does not collect any data. There are no accounts, no ads, no analytics and no tracking. Your drawings never leave your device unless you choose to share them.
Information we collect
None. Knob Sketch does not collect, store, transmit or sell any personal information. The app does not connect to any server.
Your drawings
Drawings you save are stored only on your device, inside the app’s own storage. They are removed if you delete the drawing or delete the app. If your device is backed up to iCloud or your computer, those backups may include the app’s data, as with any app. This is handled by Apple and is outside our control.
Photo library
When you export a drawing and choose to save it to Photos, iOS may ask for permission to add photos. Knob Sketch only uses this to save the image you chose to export. It cannot read or view any of your existing photos.
Motion sensors
The “shake to erase” feature reads your device’s motion sensors while the app is open. This information is processed instantly on your device to detect shaking. It is never stored or sent anywhere.
Sharing
When you use the share button, the image is passed to the app or service you pick (for example Messages, AirDrop or Instagram). What happens next is governed by that app’s own privacy policy.
Third parties
Knob Sketch contains no third-party analytics, advertising or tracking code.
Children
Knob Sketch is suitable for all ages. Because it collects no data, it collects no data from children.
Changes to this policy
If this policy changes, the updated version will be posted on this page with a new effective date.

私隱政策
生效日期：2026 年 9 月 29 日
簡而言之：Knob Sketch 不會收集任何資料。本 App 毋須註冊，沒有廣告、數據分析或任何追蹤。除非你主動分享，否則你的畫作不會離開你的裝置。
我們收集的資料
沒有。Knob Sketch 不會收集、儲存、傳送或出售任何個人資料，亦不會連接任何伺服器。
你的畫作
你儲存的畫作只會存放在你的裝置上，位於本 App 的專屬儲存空間內。刪除畫作或刪除本 App 後，相關資料亦會一併移除。與其他 App 一樣，如你的裝置有備份至 iCloud 或電腦，備份內容可能包括本 App 的資料。此備份由 Apple 處理，並非我們所能控制。
相片庫
當你匯出畫作並選擇儲存至「相片」時，iOS 可能會要求你授權本 App「加入」相片。Knob Sketch 只會用此權限儲存你選擇匯出的圖片，並不能讀取或檢視你現有的任何相片。
動作感應器
「搖動清除」功能會在 App 開啟時讀取裝置的動作感應器，以偵測搖動。有關資料只會即時在你的裝置上處理，絕不會被儲存或傳送。
分享
當你使用分享功能時，圖片會傳送至你所選擇的 App 或服務（例如「訊息」、AirDrop 或 Instagram），其後的處理方式受該 App 本身的私隱政策規管。
第三方
Knob Sketch 並未包含任何第三方數據分析、廣告或追蹤程式碼。
兒童
Knob Sketch 適合所有年齡人士使用。由於本 App 不會收集任何資料，因此亦不會收集兒童的資料。

如本政策有所修改，更新後的版本將於本頁公布，並註明新的生效日期。
