Last updated: May 10, 2026

BirdyLog is a personal bird photography record app. The app is designed to store your records locally on your device. BirdyLog does not require an account and does not operate a BirdyLog server for uploading your photos or observation records.

The app may store records you create, including bird names, scientific names, dates, locations, camera details, tags, notes, photo references, and app settings. This information is stored locally on your device.

BirdyLog requests access to your photo library so you can import selected bird photos and keep photo-based records. The app does not upload your photo library to a BirdyLog server.

BirdyLog may request location permission to help record photo locations and show your current position on the map. You can also enter locations manually.

When you use map, search, or geocoding features, location queries or coordinates may be sent to map and location service providers used by the app, such as Apple, Google, or OpenStreetMap/Nominatim, depending on the feature and platform.

BirdyLog PRO subscriptions and purchase restoration are handled by the App Store. BirdyLog may store a local purchase status so the app can unlock PRO features on your device.

For privacy questions, contact [email protected].
