Privacy Policy
Last updated: September 17, 2026
Information stored on your device
Lens Mate can store lens case names, left- and right-eye lens cycles, start dates, replacement records, language preferences, sound preferences, and optional profile details on your device. This information is used to provide the app’s tracking features.
Optional cloud backup and synchronization
If you choose to sign in, Lens Mate may process your phone number and the lens-box content that you choose to synchronize. This is used for app functionality, including cloud backup, cross-device recovery, and synchronization. Sign-in is not required for basic tracking.
NFC stickers
An official NFC sticker contains an HTTPS link with a non-personal token. The token is used to verify the official sticker and open the linked lens case. The sticker does not contain your lens records, phone number, or other personal information. The consumer app does not write new sticker content during normal binding; it reads and verifies the supplied sticker.
Service providers and security
Cloud services may be used to provide optional synchronization and official NFC-token verification. Lens Mate does not sell personal information and does not use the information described above for advertising or tracking. Network requests use HTTPS where supported.
Data choices
You can use the core tracking features without signing in. You can stop synchronization by signing out. Device-only records can be removed from the app or by removing the app from the device. For a cloud-data request, use the developer contact channel shown on the Lens Mate App Store product page and include the account information needed to identify the request. For general product help, see Support.
Children and health information
Lens Mate is a general personal utility. It does not provide medical diagnosis or treatment advice, does not connect to HealthKit, and does not intentionally collect medical records. It is not directed to children.
Changes to this policy
We may update this policy when the app’s data practices change. The latest version will be published on this page with its effective date.

隐形眼镜助手（Lens Mate）是一款以本地记录为主的个人工具。基础镜片周期记录无需登录，不使用广告，也不进行跨 App 跟踪。
App 可以在设备上保存眼镜盒名称、左右眼镜片周期、开戴日期、更换记录、语言和音效偏好以及用户主动填写的资料。用户主动登录后，手机号和选择同步的眼镜盒内容可能被用于云端备份、跨设备恢复和同步。
官方 NFC 贴纸只包含带有非个人化 Token 的 HTTPS 链接，用于验证官方贴纸并打开对应镜盒，不包含镜片记录或手机号。普通使用过程中，App 不会自行写入新的贴纸内容。
App 不出售个人信息，不将上述信息用于广告或跟踪，不连接 HealthKit，也不提供医疗诊断或治疗建议。退出登录可以停止同步；设备本地记录可以在 App 中删除或通过移除 App 删除。云端数据请求请通过 App Store 产品页面显示的开发者联系入口提出；一般使用问题请查看技术支持页。
