Privacy Policy
Last updated October 18, 2026
What we collect
Nothing. Foldie has no servers. Your to-dos, money entries and settings are stored on your iPhone; the developer can’t see them and the app never uploads them. If iCloud Backup is on, they are backed up with your phone like any other app’s data (kept by Apple). There are no ads, no tracking and no third-party analytics.
Your account
A password account’s nickname and password are kept only in this iPhone’s Keychain; the password is stored as a salted hash, never as plain text. With Sign in with Apple (including when you add an Apple account to a password account), the app keeps only the user identifier Apple gives this app — it is different for every developer and can’t be used to recognize you elsewhere — and the name you chose to share. It doesn’t keep your email and never sees your Apple Account password.
Face ID and passcode
When you unlock Foldie or verify yourself to reset a password, iOS does the check. The app only learns whether it passed; it never receives face data or your passcode.
Purchases
Foldie Pro is bought and renewed through the App Store, and Apple handles payment. The developer never receives your payment details; the app only asks the App Store whether you have a membership.
Notifications
Task reminders and the nightly bookkeeping reminder are local notifications scheduled on your phone. They don’t go through any server.
Photos
When you save a report or your welcome receipt to Photos, the app asks only for permission to add photos. It never reads anything in your photo library.
Export and sharing
Backup files and report images are created only when you tap Export, Save or Share, and you decide where they go.
Deleting your data
In Settings › Profile, tap Delete Account (Delete All Data when you’re not signed in) to remove the account and all to-dos, money entries and settings from this iPhone. Deleting the app removes your to-dos, entries and settings; the account in the Keychain is kept by iOS and cleared by the app the next time it’s installed — use Delete Account to be sure everything goes. If you used Sign in with Apple, you can also stop using it for Foldie in iPhone Settings › Apple Account › Sign in with Apple.
Children
Foldie isn’t designed for children and doesn’t knowingly collect anyone’s personal information.

隐私政策
更新于 2026 年 10 月 18 日
我们收集什么
不收集。兜兜没有服务器,你记下的待办、流水和设置保存在这台手机上,开发者看不到,App 自己也不会上传。如果你打开了手机的 iCloud 云备份,它们会像其他 App 的数据一样随手机备份(由 Apple 保管)。App 里没有广告、没有追踪,也没有任何第三方统计或分析工具。
账号
密码账号的昵称和密码只存在这台手机的钥匙串里,密码经过加盐散列处理,不保存原文。用 Apple 登录时(包括给密码账号绑定 Apple 账户),App 只保存 Apple 给这个 App 的用户标识(每个开发者看到的都不一样,不能用来在别处认出你)和你同意分享的名字,不保存邮箱,也拿不到你的 Apple 账户密码。
Face ID 与锁屏密码
解锁和找回密码时的验证由 iOS 完成,App 只知道验证是否通过,拿不到面部数据或锁屏密码。
购买
兜兜 Pro 通过 App Store 购买和续费,付款由 Apple 处理,开发者收不到你的付款信息。App 只向 App Store 查询你是否拥有会员。
通知
待办提醒和每晚的记账提醒,都是在手机上安排的本地通知,不经过任何服务器。
相册
保存报告长图或入住小票时,App 只申请「添加照片」权限,不会读取你相册里的任何内容。
导出与分享
备份文件和报告长图只在你点「导出」「保存」「分享」时生成,发给谁、存到哪里由你决定。
删除数据
在「设置 › 个人中心」点「注销账号」(没登录时是「删除全部数据」),可以删除这台手机上的账号和全部待办、流水、设置。直接删除 App 会删掉待办、流水和设置;钥匙串里的账号由 iOS 保管,下次安装时 App 会把它一并清掉。想确保全部删除,请用「注销账号」。用 Apple 登录的,还可以在手机「设置 › Apple 账户 › 通过 Apple 登录」里停止使用兜兜。
儿童
兜兜不面向儿童设计,也不会有意收集任何人的个人信息。
