License and activation, offline and one-time

A tendre.AI license is a one-time purchase, not a subscription, and it is verified entirely offline once activated.

What activation does

When you buy a license, you receive a signed license file. Opening it in the app, or pasting the key it contains, binds that license to your current machine. This check happens locally: after activation, tendre.AI works fully offline, including with the network cable unplugged or Wi-Fi off.

No account required

There is no login, no email verification loop, and no server checking in on your usage. The license file itself, together with your machine, is the only proof of ownership the app needs.

One machine per license

Each license activates on a single machine at a time. Reinstalling tendre.AI on the same computer keeps the same activation, so you can update the app or reset Windows without losing your license. Installing on a second computer requires a separate activation slot.

Moving to a new machine

If you upgrade your PC or need to move your license to different hardware, contact support from the Contact page with your order details. Support can release the old activation so you can activate on the new machine; this is a manual step to prevent one license running on many computers at once.
