Memory Palace Privacy Policy
Learn the memory palace method in 40 short sessions, walking through 3D palaces, and measure your own before and after.
- No accounts. You never sign up or sign in.
- No ads, no analytics, no tracking. The app contains no advertising or analytics SDKs and does not fingerprint your device.
- We never sell data, and we share it with no one except the providers named below, only to do what the feature needs.
1. What the app handles, and where it goes
Everything stays on your device
Your progress, settings, history and anything you create in the app are stored only on your device, in the app’s own storage. The app has no server of its own and does not send this data anywhere.
Deleting the app deletes all of it. If you use iPhone backups (iCloud Backup or a computer), the app’s data is included in that backup under your Apple ID, like any other app.
Purchases
In-app purchases are processed by Apple through the App Store. We receive no name, email, card number or address; Apple only tells the app whether the purchase is valid. The record of what you unlocked is kept on your device and in your Apple ID’s purchase history, so it can be restored on your other devices.
Bundled audio
All voice and sound files are included in the app download. Playing them involves no network request.
Read-aloud voices
Reading questions or phrases aloud uses the text-to-speech voices built into iOS. The text is spoken on the device and is not sent to us.
2. Children
Memory Palace is intended for adults and is not directed at children under 13. We do not knowingly collect personal information from children.
3. Permissions you may be asked for
| Permission | Why | If you decline |
|---|---|---|
| Notifications | To remind you when a recall test is due (20 minutes and 24 hours after studying) and, if you turn it on, at your daily practice time. | Everything still works; you just need to remember to come back on time. |
You can change any of these at any time in the iPhone Settings app.
4. Your choices and rights
- Deleting the app deletes everything it stored on your device.
- Where the law gives you rights to access, correct, export or delete personal data (for example under GDPR, the CCPA, or Fiji’s Personal Information Protection framework), you can exercise them by email. Because we hold essentially no personal data, most requests are answered by confirming that there is nothing to return.
5. Contact
Email: d60liu@gmail.com · d60lab, Suva, Fiji. We answer within 30 days, usually much sooner.
6. Changes
If this policy changes we will update this page and the effective date above. A material change is also announced inside the app.

- 没有账号。不需要注册，也不需要登录。

1. App 处理哪些信息，去了哪里
所有内容都只在你的手机上
你的进度、设置、历史记录以及在 App 里创建的任何内容，都只保存在你的设备上，存放在 App 自己的存储空间里。App 没有自己的服务器，也不会把这些数据发到任何地方。
删除 App 即删除全部数据。如果你开了 iPhone 备份（iCloud 云备份或电脑备份），App 的数据会和其他 App 一样，以你的 Apple ID 存入备份。
购买
App 内购买由 Apple 通过 App Store 处理。我们收不到你的姓名、邮箱、卡号或地址，Apple 只告诉 App 这笔购买是否有效。你解锁了什么，记录在你的手机和 Apple ID 的购买历史里，换设备可以恢复。
内置音频
所有语音和音效文件都包含在 App 安装包里，播放时不发生任何网络请求。
朗读声音
朗读题目或句子用的是 iOS 内置的文字转语音。文字在设备上播放，不会发给我们。
2. 儿童
Memory Palace 面向成年人，不面向 13 岁以下儿童，我们不会有意收集儿童的个人信息。
3. 可能请求的系统权限
| 权限 | 用途 | 拒绝后 |
|---|---|---|
| 通知 | 回忆测试到点时提醒你（学完 20 分钟、24 小时），以及你打开的每日练习提醒。 | 所有功能照常，只是要自己记得按时回来。 |
这些权限随时可以在 iPhone「设置」里更改。
4. 你的选择和权利
- 删除 App 即删除它存在手机上的全部内容。
- 法律赋予你的访问、更正、导出或删除个人数据的权利（例如 GDPR、CCPA），都可以通过邮件行使。由于我们几乎不持有任何个人数据，多数请求的答复会是"没有可返回的数据"。
5. 联系我们
电子邮件：d60liu@gmail.com d60lab，斐济 苏瓦。我们会在 30 天内答复，通常快得多。
6. 政策变更
政策有变化时我们会更新本页并修改上面的生效日期。重大变化会在 App 内提示。
