MiruJiMa Privacy Policy

Last updated: October 6, 2026

MiruJiMa (the "App") values your privacy. This policy explains what information we process and how.

1. Information We Collect

The App has no sign-up or login. We only process the following:

• Task data: task titles, categories, and dates you enter yourself — stored locally on your device.
• Cloud backup data: if you use automatic/manual backup, your task data is stored on Supabase together with a random recovery code generated on your device. This code is a random value not linked to any name, email, or other identifying information.
• Usage statistics: basic usage data such as session start/end and screen views, automatically collected via Firebase Analytics. This does not include personally identifying information.
• Advertising identifier: banner ads are shown via Google AdMob, and your Advertising ID may be processed by Google for ad personalization.
• Payment info (monthly subscription & one-time purchase): the premium monthly subscription and one-time purchase are processed through the in-app billing of the store you installed the App from (Google Play, Samsung Galaxy Store, or ONE store). Card numbers and other payment details are handled directly by that store and never reach the App or its server. Only the purchase token (or purchase ID) issued by the store is sent to the App's server, solely to verify the purchase via that store's verification API (Google Play Developer API, Samsung IAP receipt lookup, ONE store purchase API) — it is not stored separately on the server.

2. Purpose of Use

• Providing task reminders
• Providing cloud backup/restore
• Analytics to improve app stability and usability
• Serving ads
• Detecting whether you responded on the call-style reminder screen (not speech recognition)
• Verifying premium subscription and one-time purchase payments

3. Third-Party Services

The App uses the following services, each governed by its own privacy policy:

• Google Firebase (Analytics)
• Google AdMob (advertising)
• Supabase (cloud backup storage)
• Typecast / Google Cloud (voice synthesis — task title text is sent to the server to generate speech and is not stored afterward)
• Google Play billing, Samsung Galaxy Store in-app purchase (Samsung IAP), ONE store in-app purchase (payment processing and purchase verification)

4. Data Retention and Deletion

Local task data is deleted when you delete the App. To request deletion of your cloud backup data, please contact us at the address below.

5. Your Rights

You can turn off cloud backup at any time in the App's settings, and can reach out with any privacy questions at the contact below. Premium subscription cancellation/refunds are managed directly through the subscription/payment menu of the store you installed the App from (Google Play / Galaxy Store / ONE store), not through the App. A one-time purchase can be used for as long as the service is operated, and is not refundable if you have used it for one year or more, even if the service ends.
