二、账号与安全 / Account & Security

你需提供有效邮箱并设置密码。密码经不可逆散列存储，我们无法查看你的明文密码。请妥善保管账号凭据。

You must provide a valid email and set a password. Passwords are stored as irreversible hashes; we cannot see your plaintext password. Keep your credentials safe.

三、位置信息条款 / Location Information

为改进服务质量与了解产品使用分布，我们会在你使用调音器时采集位置信息，分为两档：

① 城市级（默认）：基于你的 IP 地址解析得到大致城市位置，无需任何授权，精度为城市级；

② 精确级（经你授权）：经浏览器弹窗由你明确授权后，采集设备 GPS 精确位置（门牌级），并解析为地址文本。拒绝授权不影响任何功能使用，此时仅按第①档采集。

To improve our service and understand usage distribution, we collect location information when you use the tuner, in two tiers:

① City level (default): derived from your IP address. No permission is required and accuracy is limited to city level;

② Precise level (with your consent): with your explicit authorization via the browser permission prompt, we collect your device's precise GPS location (street level) and resolve it to an address. Declining the permission does not affect any functionality; only tier ① is then collected.

四、使用统计 / Usage Statistics

我们会记录每次使用的开始时间、时长与上述位置档信息，仅用于产品改进与统计分析，不出售、不用于广告推送。

We record the start time, duration and location tier of each session solely for product improvement and statistics. We never sell this data or use it for advertising.

五、免责与变更 / Disclaimer & Changes

This tool is provided free of charge "as is"; tuning results are for reference only. Any updates to this agreement will be published on this page and remain effective thereafter.
