Privacy Policy

Last updated 2 September 2026

Birdly is made by Tony (the “developer”). This policy covers the iPhone app and the Android app. It is written to match how the apps actually work.

Short version

Your learning progress stays on your device. Birdly does not create an account, does not show ads, and does not include analytics. The apps work offline. Bird photos and lessons ship inside the app and are not downloaded from a developer server.

Information stored on your device

Birdly keeps a local record of what you have practised:

  • Learning progress — mastery for birds and images you have seen, including whether a bird has been introduced
  • Preferences — whether sounds and haptic feedback are on
  • App state — whether you have already seen the first-run splash screen

On iPhone this uses Apple’s on-device storage (SwiftData). On Android it uses Room and DataStore. That data is not uploaded to the developer and is not shared with anyone else.

Network and third parties

The developer does not run a Birdly server and does not receive your progress. Shipped bird photos and topic content are bundled with the app. The Android app does not request internet permission. The iPhone app does not need a network connection to learn.

If you tap a Settings link to the source code or the licence, the system browser opens GitHub. Anything you do there is between you and GitHub.

Birdly does not use advertising networks, analytics SDKs, crash reporters, or other data processors.

What is not collected

  • No Birdly user account, email, or password
  • No location
  • No advertising identifiers, tracking pixels, or usage analytics in the app
  • No sale of personal information
  • No iCloud, Google backup of progress to the developer, or other developer-operated sync between devices

Android may include the app’s local files in a device backup you control. That backup is not sent to the developer.

Open source

Birdly is free software under the GNU GPL v3. You can review how it works:

Children

Birdly is a general education tool. It does not collect personal information from anyone, including children. It is not directed at children under 13 as a service that gathers their data.

Your choices

  • Turn sounds and haptic feedback off in Settings.
  • Delete the app to remove local progress and preferences from that device.
  • Stay offline; learning does not require a network.

Because there is no Birdly account on a server, there is no cloud copy for the developer to delete on request. If you emailed support, that email is handled as ordinary correspondence.

Changes

If this policy changes, the updated text will be posted at this URL with a new “last updated” date. Material changes that affect how the app handles information will ship with an app update when that is needed for the change to take effect.
