If you bought SideNotes from our website, you may activate the app on 2 devices. This is how you deactivate a license from a computer.
If you have no access to the computer anymore, please contact us and we will reset your activations.
To deactivate the license, click the cog button in the right bottom of the folder list, and choose Your License option.
Now you can see your license number. To deactivate the license, simply click Deactivate License button.
