How licensing works

This page explains in plain words how the licence works in the programs. The legal terms are in the Terms of Service and the License agreement.

One account, no keys

You sign in with your e-mail address and a code we send to it — no password and no licence key. The same account works in every program of the series.
Your licences, seats and their "valid until" dates are in your account.
Signing in or out in one program does it in every program of the series on that computer, for your Windows user.

You install the free version. When you sign in with a licence or start a trial, the program downloads the Pro version as an update and restarts — no new installation.
For computers without internet, your account offers the Pro installer. Its download link is personal and works for 15 minutes.

Pro of a program runs on one computer at a time for each person. The programs are independent: Pro of one program on a laptop and Pro of another program on a desktop at the same time is fine.
The computer where you start the program last takes Pro if the program reaches our server within 10 minutes of starting. The other computer goes to Free at its next check, with a message; your projects and their Pro data stay as they are.
A program that gets a connection later does not take Pro by itself: in the Account & license window it offers "Move Pro here".
Pro can move at most 10 times a day for each program.

While online, the program checks the licence about once an hour.
Without a connection, Pro keeps working for up to 7 days from the last successful check. After that the program works as Free until it can check again. It never locks your projects.
If the computer's clock has been set back by more than 24 hours, Pro waits for a check with our server.

On a computer without internet, the program saves a request file. On another device, you upload it in your account and get a licence file for that computer, which the program imports. Look for "Computers without internet" in the Account & license window.
A computer activated offline needs no checks with our server; its seat is not used online.
A licence file works while the licence is valid. One issued during the refund period is temporary: it works for 21 days from the purchase; after that, your account gives you a file to the end of the licence.
For a seat that renews automatically, the file works 21 days more after the paid year, so that the computer does not fall back to Free on the day of the renewal. After the renewal's refund period, your account gives you the file for the new year — one file a year.
An offline seat moves to another computer with a new file from your account, after you confirm that the old file has been deleted — at most 2 times a year.

A company buys seats and assigns them to people in its account, by e-mail address. A person without an account gets an invitation by e-mail. When you buy several seats, one of them is yours at once.
A seat can be given to another person at most 2 times in 30 days — more often through our support. A seat activated offline passes only after the old offline file has been confirmed deleted. The previous holder goes to Free at the next check.
If you hold a seat from your own purchase and pass it on — for example after selling the licence or changing jobs — we transfer it on request to the end of the paid licence year, after you confirm that your copies of Pro and your offline activations for that seat have been deleted. The renewal of that seat is cancelled; after that, the new holder continues with a purchase of their own.

Pro free of charge for 30 days from the first start of Pro: one trial per computer and one per account for each program. No payment details.
The trial needs a connection when the program starts. If the connection drops while you work, Pro stays until you close the program.
A trial stays on its computer: it does not move to another one.
Documents, exports and Revit packages made during the trial carry the mark "Trial version — not for issue".
For a closed network, we issue an offline trial on request.

For current students and teaching staff of an educational institution: Pro free of charge for teaching, learning and non-commercial research, for 12 months, renewable by a new application — see Education licence.
Documents, exports and Revit packages carry the mark "Education — not for issue".

For beta testers: Pro free of charge for a term we set — we give it in your account, or you enter a promo code in your account under "Promo code".
Work of any kind, also commercial; documents, exports and Revit packages carry no mark.
When it ends, the program works as Free.

Pro runs while your licence is valid, up to its "valid until" date. When a licence ends — the paid year ends without renewal, a refund, early termination by a consumer, termination for a breach, or the end of a trial, an education licence or a beta licence — the program works as Free. No version stays Pro.
Every project still opens in Free. Its Pro data are kept and saved unchanged, but locked — read-only in Free: Free does not change, delete or recalculate them, shows that Pro is needed where their figures no longer match the data they depend on, and refuses an action that would break them. With a valid licence they work again.
Documents you exported while the licence was valid stay yours.
If a renewal payment fails, Pro keeps working while Paddle retries the payment, and the program asks you to update your card in your account. Pro ends when Paddle finally cancels the subscription, and at the latest 30 days after the paid year.
If our licence service ever closes, we release a permanent unlock of all paid versions before it closes.

Updates lead only to the latest version. Free gets them always, Pro while your licence is valid: each version comes out as Free and Pro together.
After your licence has ended, the next update installs the Free version, and the update window says so. When you renew, Pro comes back.
Fixes, including security fixes, come only in the latest version, as a new version.
Each program gets security updates for at least 5 years from its first release with Pro on sale; the month and year are on the Security page.

The program does not send the Windows name of your computer. It sends a hash of the computer's identifier and a device label that you choose and can change. Your account shows the label, so you can see where Pro runs.

Without Pro or a trial: just the weekly update check, which names only the program (you can switch it off), and what you ask for yourself — signing in, the trial, downloading Pro, a problem report.
With Pro or a trial: at the start and about once an hour — your session, the licence, the hash of the computer's identifier, the device label, the program and its version.
Never your projects, except a file you attach to a problem report yourself. Details are in the Privacy policy.
