License Keys
Your license key was issued at purchase and shown on the confirmation screen. It was also included in your receipt email from Lemon Squeezy.
The key unlocks licensed features inside the application. If you can't find your key, check your email for the Lemon Squeezy receipt.
Your Data
KEEP stores all data locally on your machine, separate from the application itself.
Uninstalling KEEP does not delete your data. Reinstalling or updating preserves everything — your portfolios, sleeves, and settings remain intact.

You can verify file integrity by comparing the SHA-256 checksum shown on the downloads page against the file you downloaded.
