Email support@kikumark.com with a brief description, the approximate time of the issue, your KikuMark app version and, if possible, a screenshot or the error text. We help with: login and email verification, study records, subscription status, purchase restoration, quota display, transcription failures, and deletion or privacy requests.
In the app: Account → Delete Account. KikuMark then deletes or anonymizes data linked to the account, including vocabulary and study cards, practice history, quiz results, listening level and progress, in-app preferences, content interest tags and quota records. Records required by law or necessary for payment disputes, fraud prevention or security may be retained for the necessary period, and Google Play / the Apple App Store / RevenueCat may keep required transaction records.
Users may also contact support@kikumark.com to request deletion of specific data or all personal data associated with their account, without necessarily deleting the account.
Email support@kikumark.com with the subject "KikuMark Data Deletion Request" and the email address registered with KikuMark. We verify the request and complete reasonable deletion within 30 days. Uninstalling the app does not delete your account; deleting your account does not cancel a subscription.
发送邮件至 support@kikumark.com，简要说明问题、大致发生时间、KikuMark 应用版本，并尽可能附上截图或错误提示文字。常见问题包括：登录与邮箱验证、学习记录、订阅状态、恢复购买、额度显示、转写失败、删除与隐私请求。
在 App 内：「账户」→「删除账户」。KikuMark 将删除或匿名化与账户关联的数据，包括词语库和学习卡片、练习历史、课后测试结果、听力等级和进度、应用内偏好、内容兴趣标签及额度记录。法律要求保留或为付款争议、防欺诈及安全所必需的记录可能保留必要期限；Google Play / Apple App Store / RevenueCat 可能保留必要的交易记录。
用户也可以通过 support@kikumark.com 要求删除与账号相关的部分数据或全部个人数据，而不一定需要删除账号。
发送邮件至 support@kikumark.com，标题注明"KikuMark 数据删除请求"，并说明注册 KikuMark 使用的邮箱。我们核实请求后会在 30 日内完成合理可行的删除。卸载 App 不等于删除账户；删除账户不等于取消订阅。
