Updating

• Update from the app (recommended) — When you run the app, it checks for a new version after a moment, and if there is one, the An update is available window shows what's new. Click Install now and the update is downloaded, checked and installed, and the new version starts automatically. You can also check yourself with Settings → Updates → Check now → FAQ — Updates.
• Install it yourself — Download the new installer from this page and install it; the old version is removed and the new version installed. Your photo list, ratings, tags, edits, settings and license stay as they are.
• If a newer version is already installed, installing an older version stops with the message "A newer version of photoKam Radar is already installed."
• You can also reinstall the same version. If the app isn't working properly, try reinstalling it (your data stays as it is).
• macOS — Same as Windows. Click Install now in the app's An update is available window.

Uninstalling (Windows)

1. Find photoKam Radar in Windows Settings → Apps → Installed apps (or Control Panel → Uninstall a program).

2. Click Uninstall

   The running photoKam Radar and the background indexer are closed, and the setting that starts the indexer automatically when the computer turns on is removed as well.

• Your original photos are not deleted. Only the program is removed.
• The data folders are kept — they hold your photo list, ratings, tags, edits, settings, license and thumbnails. So if you reinstall, you can pick up exactly where you left off.
• To delete all data — Before uninstalling, note down the Database path and Cache path under Settings → Storage, then delete those folders after uninstalling the program. This also removes your ratings, edits and license, so you'll need to register your license again if you reinstall.

Uninstalling (macOS)

1. Turn off "Start automatically at logon" in Settings

   This removes the background indexer's automatic start entry (~/Library/LaunchAgents/com.photokam.radar.qt.indexer.plist).

2. Quit photoKam Radar.
3. Move photoKam Radar from the Applications folder to the Trash.

• Your original photos are not deleted.
• The data folders remain even after you delete the app — if you reinstall, you can pick up exactly where you left off.
  • ~/Library/Application Support/com.photokam.radar.qt — photo list, ratings, tags, edits, settings, license
  • ~/Library/Caches/com.photokam.radar.qt — thumbnails
• To delete all data, delete the two folders above after deleting the app. Your license is removed too, so you'll need to register it again if you reinstall.

System requirements

• Your photos, videos and edits are all stored only on this PC. Photos are never sent over the internet → FAQ — Data · Privacy.

Free and full versions

• Anyone (individuals, companies, institutions, including commercial use) can use every feature in the free version.
• The only difference between the free and full versions is the watermark. In the free version, a faint diagonal "photoKam Radar · Free" watermark is added to exported photos and slideshows (the editor and the full view also preview the same watermark on edited photos. However, photos that were only rotated 90° without opening the editor show no watermark in the full view or slideshows).
• To use the app without the watermark, buy and register a full license. One license lets you use the app on one PC with no time limit.
• Price and purchase: Regular price ₩49,000, now ₩29,000 until October 15, 2026 (on sale). You can buy it at Naver Smart Store.
• For how to register, see Free version · Full version · License registration.
• Terms of Use · Privacy Policy · Open-source notices (also available in the app's About window → Open-source notices)
