Activating Towfu Pro
Your licence key came by e-mail right after you paid. It looks like this:
TOWFU-7K2QD-M9XVB-3HT0C-WPR4N-E8JZA
Activate
- Open Towfu and go to Settings → Licence.
- Paste the key. Spaces, dashes and upper or lower case don't matter.
- Click Activate. Towfu needs the internet for this one step.
That's it. Towfu confirms the licence quietly in the background at most once a day, never at startup, and works offline in between.
Check a key for typos
This check runs entirely in your browser. Nothing is sent anywhere.
Using more than one computer
One licence covers one person on up to 3 of their own computers at the same time, for example a desktop, a laptop and a work PC.
Moving to a new computer
- If you still have the old computer: in Towfu go to Settings → Licence → Deactivate. That frees its place straight away.
- If you don't: activate on the new computer. If all places are in use, Towfu lists your activated computers with the date each was last used. Choose Deactivate next to the old one, then activate again.
- Reinstalling Towfu on the same computer doesn't use up a place.
Lost your key?
Enter the e-mail address you used at checkout and we'll send every Towfu key linked to it. For privacy, the reply is the same whether or not the address has a licence.
Your order is also in Paddle's receipt e-mail, which links to your purchase. Still stuck? E-mail from any address and tell us roughly when you bought it.
If activation doesn't work
| Message | What to do |
|---|---|
| "That key has a typo" | Copy the key from your e-mail again, or check it above. |
| "We couldn't find that key" | Check you're using the newest key e-mail. Use Lost your key? to get all your keys again. |
| "Already active on 3 computers" | Deactivate one from the list Towfu shows. See Moving to a new computer. |
| "Couldn't reach the licence server" | Check your connection, VPN or company firewall. Towfu needs to reach the licence server once to activate. |
| "Moved between computers a lot recently" | A safety limit for shared keys. E-mail support and we'll reset it. |
| "This key was refunded" | Refunded keys stop working. If that's wrong, e-mail support. |
Offline, trials and what happens without a licence
- Offline: Towfu keeps working. If it hasn't been able to confirm your licence for about 90 days, Settings asks you to connect once. Nothing else changes.
- Trial: every new computer gets a 14-day trial of all Pro features, with no sign-up.
- No licence: Towfu runs in the free Community mode. Nothing is deleted or locked; extra panes are hidden and come back when you activate.
- Updates: every update released while your subscription is active is included. If you cancel, Towfu Pro keeps working until the end of the month you've paid for, then Towfu switches to the free Community mode. Nothing is deleted.
What activation sends
Your key, a one-way fingerprint of your computer (derived from the Windows machine ID, so we can count your computers without knowing what they are) and the computer's name as shown in Settings, which you can change. Nothing about your projects, prompts or AI accounts. See the privacy policy.
