trail app privacy policy
Last updated: October 23, 2026 ・ Support ・ 日本語
Summary
trail (“the app”) sends the posts and photos you write to your own GitHub repository. The developer does not collect any information about you. The app contains no analytics or advertising and does not communicate with any server run by the developer.
GitHub sign-in
- When you sign in, the app receives an access token from GitHub and stores it in the device Keychain (this device only, not synced to iCloud).
- The token is used only to list the repositories where you installed the GitHub App “Trail Blog Post” and to commit your posts. The app can write only to the repositories you selected when installing it.
- Signing out deletes the token from the device. You can revoke access at any time in GitHub Settings → Applications.
Posts and photos
- Posts (title, body, tags and so on) and photos are sent directly from your device to GitHub and stored in your repository. If the repository is public, anyone can see its contents.
- The app reads only the photos you pick in the system photo picker. Before sending, photos are redrawn and all metadata, including location, capture time and camera model, is removed.
- Drafts and their photos are stored only in the app’s storage on your device and are deleted after posting or discarding.
Place names
Only if your blog type uses place names, the app looks up a place name (for example, “Naha”) from the location of the first photo you pick. To do this, the location is sent to Apple’s map service. Latitude and longitude are never saved or sent to GitHub.
