Lap is an open-source, local-first photo manager for browsing family albums, finding old photos quickly, and managing large personal media libraries offline. It is a privacy-focused alternative to cloud photo services: no forced upload, local AI search, folder-first workflow, and free to use.

Why Lap

Features

Metadata, Collections, and Moving Files

Lap is folder-first, but not every piece of information shown in Lap is embedded in the original file. This distinction matters when you also manage the same folders in Finder, Explorer, or another photo app.

What stays with the file

What is stored locally by Lap

The following are Lap library data. They are stored in Lap's local database or library configuration, not written into EXIF, IPTC, or XMP sidecars:

This data does not travel with a file when it is copied, exported, or moved outside Lap, and it is not available automatically to other applications.

Working with files outside Lap

Lap can rescan folders and detect many filesystem changes. But changes made outside Lap—such as renaming, moving, replacing, or copying files—can disrupt organization that is stored only in Lap.

For the most reliable results, rename and move files in Lap whenever you rely on Collections, Tags, Comments, Favorites, Ratings, or culling states. If you also manage files outside Lap, back up Lap's database and configuration together with your photos. You can manage the database location and create a backup in Settings → Storage.

Deleting Lap's database or configuration removes this local organization and index data, but does not delete your original media files.

Uninstall Lap

Lap works directly with your existing photo folders. Uninstalling Lap, or deleting its database and cache files, does not delete your original photos.

The standard uninstall steps remove the application. To remove Lap completely, quit Lap first, uninstall the application, then delete its local database, thumbnail cache, and configuration files using the cleanup command for your platform.

macOS

If you installed Lap with Homebrew:

brew uninstall --cask lap

For a manual installation, quit Lap and move Lap.app from the Applications folder to the Trash.

To remove all Lap database, cache, and configuration files:

rm -rf "$HOME/Library/Application Support/com.julyx10.lap" \
       "$HOME/Library/Caches/com.julyx10.lap" \
       "$HOME/Library/WebKit/com.julyx10.lap"
rm -f "$HOME/Library/Preferences/com.julyx10.lap.plist"

Windows

Open Settings > Apps > Installed apps, find Lap, and select Uninstall.

Then open PowerShell and remove all Lap database, cache, and configuration files:

Remove-Item -Recurse -Force -ErrorAction SilentlyContinue "$env:LOCALAPPDATA\com.julyx10.lap"
Remove-Item -Recurse -Force -ErrorAction SilentlyContinue "$env:APPDATA\com.julyx10.lap"

Linux

For DEB installations, uninstall the package:

sudo apt remove lap

For AppImage installations, quit Lap and delete the downloaded .AppImage file.

Then remove all Lap database, cache, and configuration files:

rm -rf "$HOME/.local/share/com.julyx10.lap" \
       "$HOME/.cache/com.julyx10.lap" \
       "$HOME/.config/com.julyx10.lap"

If you selected a custom database storage directory in Lap settings, delete that directory separately after confirming that it contains only Lap database files.
