# MouseTuner Privacy Policy

MouseTuner collects no personal data; each mouse's settings stay on your Mac.

Last updated: October 25, 2026

MouseTuner does not collect, store or transmit any personal data. It contains no analytics, advertising or third-party SDKs.

- Each mouse's settings (speed and scroll direction) are stored only on your Mac, keyed by the mouse's vendor ID, product ID and name.
- Reversing the scroll direction requires the Device Control and Data Access permission (called Accessibility on macOS 26). MouseTuner only handles scroll-wheel events to flip the direction of the mice you choose. It never reads keyboard input and never records or sends any events.
- MouseTuner does not connect to the internet.

Deleting MouseTuner removes all of its settings.

MouseTuner 不收集、不存储、不上传任何个人数据，也不包含任何统计、广告或第三方 SDK。

- 每只鼠标的设置（速度、滚动方向）只保存在你的 Mac 上，用鼠标的厂商 ID、产品 ID 和名称区分。
- 反转滚动方向需要「设备控制和数据访问」（macOS 26 叫「辅助功能」）权限。MouseTuner 只处理滚轮事件、翻转所选鼠标的滚动方向，不读取键盘输入，不记录、不发送任何事件。
- MouseTuner 不联网。

删除 MouseTuner 即可清除它保存的全部设置。
