Privacy Policy

Last updated: June 9, 2026

Y.M Apps (an individual developer, PINO; “we”, “us”, or “our”) respects your privacy. Across the apps, browser extensions, web games, LINE stickers, and other products we provide (collectively, the “Services”), our core principle is to collect as little information as possible. This Policy applies to all of our Services. If an individual app involves any additional handling of data, we will note it in that app's store listing or in the “Per-app notes” section below.

1. Information We Collect

We do not, as a rule, collect personal information such as your name, address, or phone number on our servers. We do not operate servers for the Services. Data such as app settings, reading positions, progress, and scores is, as a rule, stored locally on your device.

2. Cloud Sync (Optional)

Some apps integrate with cloud storage services (e.g., Dropbox) only when you choose to enable the feature.

  • Integration is off by default and runs only after you explicitly connect an account.
  • Synced data (e.g., reading position, settings, files you select) is exchanged through your own cloud account and does not pass through our servers.
  • Handling of data within a cloud service is governed by that service's own privacy policy.
  • You can disconnect the integration at any time from the app's settings.

3. Crash Logs & Diagnostics (Optional)

If an app terminates unexpectedly, we may ask you to share an error log to help us improve. Sharing is opt-in and occurs only with your consent. Logs do not include information that could identify you, such as file names, file paths, or the contents of your books or other content.

4. Advertising, Tracking & Analytics

We do not serve third-party advertising and do not track you for the purpose of identifying you. If we ever introduce usage-analytics tools, we will inform you in advance via this Policy or the relevant app's listing.

5. Device Permissions

Apps use device permissions only to the extent necessary to provide their features. For example:

  • Storage / file access: to open files you select (PDFs, images, etc.).
  • Accessibility: to perform actions such as turning off the screen; it is not used to collect or record screen contents.

Every permission is limited to what is required to operate the relevant feature.

6. Children's Privacy

The Services do not knowingly collect personal information from children.

7. Data Retention & Deletion

Data stored on your device is removed when you uninstall the app. Data synced to the cloud can be managed and deleted within your cloud service.

8. Third-Party Services

The Services may use third-party services such as the following, for example when you enable them. Please review each provider's policy for how it handles data.

  • Dropbox (cloud sync) — Privacy Policy
  • Google Play (Android app distribution) — Privacy Policy

9. About This Website

This website (ymapps.pages.dev) uses only a simple aggregate visit counter. It does not use tracking cookies or analytics to follow individuals.

10. Per-App Notes

There are currently no additional matters to note beyond the above. We will add any new handling of data here.

11. Changes to This Policy

We may revise this Policy in response to changes in law or improvements to the Services. We will announce any significant changes on this page.
