KeyKeeper is a license manager with password protection, key storage, and iCloud synchronization. The full version costs $11.99.
Nowadays, storing software license keys isn’t as relevant as it used to be, since most things work on a subscription basis. Still, there are apps that require you to store activation data somewhere.
That’s where tools like KeyKeeper come in — and that’s exactly what I want to talk about today.
How Data Storage Works
Overall, KeyKeeper functions similarly to a regular password manager. When you first launch the app, you’ll be asked to set a password to access the database.

This password can only be reset if you correctly answer a security question — keep that in mind, as there's no "forgot password" button to request a reset.
You can then start adding license data manually or import a pre-made list in .csv
format.

Each license entry can include all the necessary details: software name, publisher’s website, registered name and email, license key, and download link.

You can also attach a file, add custom fields, and assign a category.
The developer's website doesn’t mention any file size limits, but I was able to attach a 7MB file without any issues.
Besides categories, entries can be added to favorites. There are no other ways to organize licenses, but the app includes convenient search and filtering options.

All information can be synchronized with other devices via iCloud.
Pricing
KeyKeeper can be tried for free. The only limitation is the inability to import or export data. The full version is available for $11.99.
