删除账号与数据
应用内即时删除
推荐在应用中打开“设置 → 账号 → 删除账号”。重新验证登录后，应用会删除 Firebase Authentication 账号、私人 Firestore 对话与问答、额度和会话绑定，并清除设备本地历史、待同步记录和 API Key。
无法使用应用时
使用注册账号对应的邮箱发送邮件至 support@gaoerji.net，主题写“AI伴学账号删除请求”，并说明无法在应用内删除的原因。不要提供密码、API Key、身份证完整号码或 Firebase token。我们会进行必要的账号归属核验，通常在7个工作日内完成。
删除和保留范围
购买提醒：去除 APP 广告为一次性购买，没有自动续费。删除账号或卸载 APP 不会自动退款，也不会删除 Google Play 订单。购买与原 AI伴学账号绑定；删除账号后如需恢复权益，请联系支持，不要发送购买令牌。
- 删除：登录账号、私人对话、全部问题和回答、私人会话绑定、额度与权益状态、设备本地密钥和缓存。
- 可能保留：不含账号身份的公开视频知识缓存；履行法律义务、防欺诈或解决争议所需的最少安全记录。
Delete your account and data
Purchases: the ad-free upgrade is a one-time purchase with no automatic renewal. Deleting your account or uninstalling the app does not automatically refund or erase your Google Play order. The purchase is linked to your original TubePal account; contact support if you need help restoring it after account deletion. Do not send purchase tokens.
In the app, use Settings → Account → Delete account for immediate authenticated deletion. If you cannot access the app, email support@gaoerji.net from the account email. Do not send passwords, API keys, identity-document numbers or Firebase tokens. We normally complete verified requests within seven business days. The Firebase account, private conversations, questions, answers, entitlements and local credentials are deleted. De-identified public-video knowledge and minimal legally required security records may remain.
