At the end of the trial period, you will get this window when opening the app:

This is when the app will need a license key to continue working. To obtain one, click Check Pricing on the popup window or alternatively, go to https://tagitize.app/pricing/
After payment, our server will immediately email you a new license key. To avoid this email landing in Spam, add support@tagitize.app to your email whitelist.
Next, copy the license key, return to the popup window above, paste your license key into the text field under the Activate section and click Apply. If the key is valid, the app will open as normal.
