The free plan carries on as before. ## Questions Support contact will be added before launch. ### Does it work offline? Yes. Ytan runs on your machine. The licence is checked on the machine itself and refreshes in the background every few days; offline it keeps working for 30 days. ### How many machines? One licence is for one person on up to 3 machines at a time. `strata logout` frees a machine, or remove one on the [account page](https://ytan.dev/account/). ### Can I use it in CI? Yes. `strata licence ci-token` makes a 90-day licence for CI secrets that does not use a machine. ### Can I move from Pro to Pro + Agents? Yes, with the same key. Monthly and yearly plans change in the account portal and pay only the difference for the rest of the period. Lifetime Pro moves to lifetime Pro + Agents for $100 once. ### How do refunds and cancelling work? Any first charge is refunded in full within 14 days, no questions. Cancel any time in the account portal: the plan runs to the end of the period you paid for and does not renew. ### Who handles payments and invoices? Polar sells Ytan as the merchant of record: it takes the payment, works out VAT and sales tax, and sends the receipt. Invoices with your company and VAT number are in the account portal. ### Teams? Each person needs a licence. For five or more, Support contact will be added before launch.. --- # Get started: Ytan > Open Ytan Studio in your browser.
