License and activation#
The model#
Maystro is sold as a yearly subscription for one machine, with a perpetual fallback: the last version you installed keeps working after the subscription ends. What ends is updates and new model support.
Trial licenses#
A trial key is the full product for 30 days on one machine, with no perpetual fallback: when the trial ends the app stops until a yearly license is added. Everything on disk stays — projects, models, settings — and so does the key: a purchase turns the same key into a yearly license. If the trial has already ended, activate once more with it. The account page shows the plan as Trial and the end date.
Activation and the token#
Activation binds your license key to a fingerprint of the machine and stores a signed entitlement token in the install folder. The token is what the app and the package index check; the raw key is not kept on disk.
| Situation | What happens |
|---|---|
| Normal use | The token is validated locally on every start. No connection needed. |
| Online, token about a week old | The launcher renews it silently when you start Maystro online, and once a day while it is open. |
| Offline for a long time | The app keeps working through a grace period measured in weeks; then it asks for one online check. |
| Subscription ended | Updates stop; the installed version keeps working. |
| Trial ended | The app stops until a yearly license is added; your projects and models stay on disk. |
| License revoked (refund, chargeback) | Takes effect at the next renewal, within a week while online. |
Other changes made by support — a trial turned into a yearly license, an extended subscription — land the same way, at the next renewal: within a week while you are online.
Machines#
One machine per license. A hardware upgrade that changes the fingerprint (new motherboard, new system drive) counts as a new machine. Deactivate the old machine from your account page, then activate on the new one with the same key. If the old machine is gone, write to support@maystro.ai with your key.
What leaves the machine#
Only activation and renewal requests (license key or token plus the machine fingerprint), update checks against the package index, and model downloads. Activation and renewal also report the machine's hardware — GPU model, VRAM and RAM size, Windows version, launcher version — so support can see what you run; nothing else. Prompts, images, videos and datasets never leave the machine.
