This privacy policy describes how Oikakeru (the “app”) and its supporting backend (the “API”) handle data. The app is operated by jaamdev as an independent developer (the “developer”).
Oikakeru does not require an account. No email, username, password, phone number, name, age, or any other identifying information is requested or collected.
Your tracked anime/manga library, progress, scores, reviews, notification schedules, achievements, and settings are stored exclusively in the local SQLite database on your device. The developer does not have access to this data. Cached cover images may also be stored on the device.
You may export your full profile to a JSON file at any time. The file is generated locally on your device and shared via the Android system share sheet to a destination of your choice. The developer never receives or stores this file.
When you search for an anime/manga or open its detail screen, the app sends a request to the API. The request body and parameters consist of:
The API does not retain logs of these requests. IP addresses are processed only transiently for rate-limiting purposes and are stored in an in-memory key/value store with a maximum lifetime of 24 hours, after which they are automatically discarded. No persistent server-side log of user activity is kept.
The API enriches anime/manga metadata using the following public sources:
These services may apply their own logging and policies on the API’s outbound requests; user-identifying data is not forwarded to them.
Notifications you configure (e.g., “alert me when a new chapter releases”) are scheduled and delivered locally by your device. No notification data leaves your device.
Oikakeru is not directed at children under 13. The app does not collect personal data from any user.
Because no personal data is collected or stored on the developer’s infrastructure, there is no profile to access, correct, or delete on the developer’s side. You may delete all app data at any time by uninstalling the app or by clearing app storage in Android settings.
All API traffic uses HTTPS (TLS 1.3). Local on-device data is protected by Android’s app sandbox.
If this policy changes, the new version will be published at the same URL with an updated effective date.
