Privacy Policy

App: WorkoutDiary
Last updated: November 9, 2026

1. Information We Collect

WorkoutDiary stores workout data entered by the user (exercise names, weights, reps, dates, and notes) only on your device. This data is never transmitted to external servers.

2. Analytics and Crash Reporting

This app uses Google Firebase services to improve app quality and understand usage patterns.

Data collected by these services is sent to Google's servers. For Google's privacy policy, please visit:
https://policies.google.com/privacy

3. Advertising

This app displays advertisements through Unity LevelPlay (mediation). LevelPlay and its partner ad networks may collect information such as your device's advertising identifier (IDFA) and IP address for ad delivery purposes.

Personalized ads require your consent through the tracking permission dialog shown at app launch. If you decline, non-personalized ads will still be displayed.

4. In-App Purchases

This app offers subscriptions through Apple's StoreKit. Payment information is managed by Apple, and the developer does not have direct access to your credit card or payment details.

5. Sending Feedback and Bug Reports

Only when you send a message from "ご意見・不具合を送る" (Send Feedback) in the Settings screen, the developer receives the following information. Sending is optional, and all features of the app are available without it.

- The text you entered and its type (request, bug, or other)
- App version, iOS version, device model, language setting, and the time it was sent

We do not receive your name, email address, or any identifier of your device, so we cannot reply to you individually. Please do not include personal information such as your name or contact details in the message.

The information is used only to fix bugs and improve the app, and is deleted when no longer needed. It is stored using Supabase, a cloud database service (storage location: Tokyo, Japan). Connection logs (such as IP addresses) are temporarily kept by Supabase's systems, but the developer does not use them to identify senders. To prevent a large number of messages from being sent in a short time, the sender's IP address is converted into an irreversible form (a hash) and kept for at most one day. Supabase acts only as a storage provider, and the information is not shared with any other third party.

6. Data Storage

All workout data is stored in your device's local storage. Deleting the app will permanently remove all data.

7. Third-Party Sharing

This app does not share your personal information with third parties, except for information necessary for ad delivery.

8. Children's Privacy

This app is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13.

9. Changes to This Policy

This privacy policy may be updated as needed. Any changes will be communicated by updating this page.
