# License and Macs

Fourteen days of everything, then one payment. No account, three Macs, every update of the current major version.

*Written from Teserra 1.3.16.*

**In short**

1. Use everything for fourteen days, with no account and no card.
2. **Get Teserra**: checkout opens in your browser, the key arrives by email.
3. Paste it in **Settings → License**. One license, three Macs.

## The trial

Everything works for fourteen days, no account, no card. A small chip in the toolbar counts the days: “Trial · 9 days left”. When it ends, the app asks for a license and your library stays exactly where it is, readable with or without Teserra.

![Settings, License during the trial: Buy Teserra with a Get Teserra button, Not activated, and an empty license key field.](https://teserra.app/assets/snips/license.webp)
*During the trial, Settings › License is where you buy Teserra or paste your key.*

## Buying

Click **Get Teserra** in the app, or the trial chip, or go straight to [teserra.app/buy](https://teserra.app/buy). Checkout opens in your browser, handled by Stripe. Your license key arrives by email within a minute. Paste it in the app: done. The price is $29, taxes included where they apply.

## Three Macs

A license activates on up to three Macs. When all three are taken, activate the fourth from **Settings → License**: it shows the list of machines with their last activity, and **Sign out** frees one on the spot. No support ticket needed.

## Updates

Teserra checks for updates when it starts. When one is ready, **Update available** appears in the sidebar and a badge on the Dock icon; a click shows the release notes for everything you missed. Every update of the current major version is included. A future major version may be a paid upgrade, announced in advance.

## Lost your key

In the app, **Lost your key?** then **Send my key** emails it again to the address you bought with. Or write to [hello@teserra.app](mailto:hello@teserra.app) from that address, and we resend it.

## Refunds

Not for you after all? Write within fourteen days of purchase and we refund you. [Terms](https://teserra.app/legal/terms)
