What this does
Your license key activates TRESSO on your computer. There is no sign-in and no account to remember - the key is what TRESSO checks.
How to use it
- Enter your license key when TRESSO asks for it.
- Keep the key somewhere you can find it again; it is also in your purchase email.
Good to know
TRESSO works offline for ordinary use. It checks your license periodically rather than on every action, so a brief loss of internet never stops you from working.
To change your payment details or cancel, use the billing link in your purchase email or in Settings. That opens your own billing page, where you manage the subscription directly.
