Terms
The short version: one payment, three Macs, every update of the current major version, and your files always stay yours.
Updated September 16, 2026
The license
Teserra is sold as a one-time purchase of $29, taxes included where they apply. A license lets one person install and use Teserra on up to three Macs they own or control. It includes every update of the current major version. A future major version may be a paid upgrade, announced in advance.
Free trial
Everything works for 14 days without a license or an account. When the trial ends, the app asks for a license. Your library is untouched: it is a folder on your disk, readable with or without Teserra.
Refunds
If Teserra is not for you, write to [email protected] within 14 days of purchase and we refund you through Stripe. A refunded license is deactivated.
What you may not do
Share, resell or publish a license key. Bypass the license check. Redistribute the app or its parts. Reverse engineer it beyond what the law allows.
Your content
Everything you put in a vault is yours. We claim no rights to it and never access it.
Third-party services
The Curator uses an AI provider you configure with your own key, under that provider’s terms and pricing. We are not responsible for their availability or their charges.
Warranty and liability
Teserra is provided as is. We work hard to keep it reliable and to fix what breaks, but we cannot promise it is free of defects or fits a particular purpose. To the extent the law allows, our liability is limited to the price you paid.
Changes
We may update these terms. The date at the top tells you when. Continued use after a change means you accept it.
