Tisty terms of use
The terms for using Tisty, taken as they stand from its repository.
Last updated: November 3, 2026
The short version
Tisty is free software you run on your own computer. There is no account, no subscription and no service of ours in between: your notes, documents and tasks stay on your disk, or in a place you choose. You may use it for anything, at home or at work. It comes with no warranty, and keeping your data safe — a backup, a sync you trust — is in your hands.
What these terms cover
The Tisty desktop app for Windows and macOS, the tisty command that comes
inside it and opens the door for assistants, the plugins and the tisty-mcp
launcher that connect assistants to it, and the website
www.tisty.app.
Folio by Tisty, the service that shares a document by link, is not covered here: it is a separate service, with its own terms and policies in its own repository.
The licence comes first
Tisty is licensed under the GNU Affero General Public License, version 3. These terms take nothing away from the rights that licence gives you, and where the two disagree, the licence wins. Organisations that cannot accept the AGPL can ask for a commercial licence.
No account, no service of ours
Tisty does not need an account and we do not operate a server that holds your data. What the app does on the network, and when, is described in full in the privacy policy.
Your data, your choices
- What you write in Tisty is yours. We claim no right to it, and we cannot see it.
- Keeping it safe is up to you. Tisty writes an append-only history and offers backups, but a disk that fails, a folder you delete or a sync you turn off can still lose work. Keep a backup somewhere else.
- When you sync through a folder, Google Drive, OneDrive or a WebDAV server, your copies live with that provider, under its terms.
Assistants
If you connect an AI assistant, Tisty lets it file tasks and write documents through MCP, within the limits described in the documentation. It never closes or deletes anything on its own: when it says a task is done, you decide. What the assistant reads is sent to whoever runs it, under that provider’s terms. You choose which assistants to connect, and you can close the door to all of them in Settings › Assistants.
Updates
Tisty checks whether a newer version exists and offers it to you; updates are signed, and Tisty refuses one whose signature does not match. A copy from the Microsoft Store is updated by the Store.
No warranty
Tisty is provided “as is”, without warranty of any kind, express or implied, including fitness for a particular purpose, as set out in sections 15 and 16 of the AGPL.
Limitation of liability
To the extent the law allows, the authors of Tisty are not liable for any loss or damage arising from its use, including lost or corrupted data, lost work or interrupted business. Some places do not allow these limits; there, they apply as far as the law permits.
Changes to these terms
Any change is committed to the public repository with a clear message and updates the date above. Using a version of Tisty released after a change means accepting the terms as they stood when it was released.
Governing law
These terms are governed by the laws of Chile, without regard to its conflict of law rules, and leave untouched any consumer rights the law of your country gives you.
