OiSee / PRIVACY
Privacy Policy
For OiSee日本語, OiSee中国語 and oisee.jp
Updated: November 1, 2026
Scope
This policy explains information handling in the OiSee日本語 and OiSee中国語 apps and on the official oisee.jp website.
1. Learning information
No account is required. Progress, quiz results, learned or missed words, and voice and speed settings are stored on the device. The apps do not provide a feature that uploads these learning records to our servers.
2. Audio
Playing learning audio does not send the text or user recordings to our servers. The apps do not include microphone recording. Recorded playback is being prepared for the Chinese app. Versions using system speech may also be subject to Apple’s policies.
3. In-app purchases
Purchases and restoration are handled through Apple’s App Store and StoreKit. Verified transaction information from Apple is used to confirm access to materials. We do not directly receive full payment card numbers.
4. Support emails
If you contact support, we may process your email address, message and troubleshooting details you choose to provide, in order to reply and resolve the issue.
5. Advertising, analytics and the website
The apps do not integrate third-party advertising or separate behavioral analytics. This website does not use advertising or behavioral analytics cookies. It stores the selected display language in the browser.
The hosting service may record access logs such as IP address, access time and browser information. Apple and hosting services may process information under their own policies.
6. Children
The apps do not ask for names, ages, dates of birth or location information. The Chinese app’s App Store age rating is 4+. A parent or guardian should provide only necessary information when contacting support about a child.
7. Deletion and contact
Deleting the app removes locally stored learning records; operating system backups may retain copies. Clearing browser site data removes the website’s language setting. For questions about personal information in support emails, contact support@oisee.jp.
8. Changes
If features or information handling change, we will update this page and any required App Store disclosures.
