Terms of Service

Simple tools, simple terms.

Summon is a free browser extension. These terms exist because every product needs them — not because there's anything complicated going on. Here's the plain-language version of what you agree to by using it.

Last updated · July 2026
The short version
Summon is free, for personal and commercial use alike.
The code is open source — you can read, audit and contribute to it.
It is provided as is, without warranties; use it at your own discretion.

Acceptance of these terms

By installing or using Summon, you agree to these terms. If you don't agree with them, simply don't use the extension — there is no account to close and nothing to cancel.

The service

Summon is a command palette for Chrome: it searches your open tabs, bookmarks and history, and bundles small utilities such as a calculator, a password generator and a QR code generator. Everything runs locally in your browser — Summon has no backend, no account and no paid tier.

License and open source

Summon's source code is open source and available on GitHub. Your use of the code itself is governed by the license in the repository. These terms cover your use of the packaged extension distributed through the Chrome Web Store.

Acceptable use

Use Summon as a browser tool, the way it's intended. Don't attempt to repackage it under the same name in a way that misleads others, and don't present a modified copy as the official one. That's it.

No warranty

Summon is provided “as is”, without warranty of any kind, express or implied. We don't guarantee it will be uninterrupted, error-free, or fit for a particular purpose — though we work hard to make it reliable.

Limitation of liability

To the maximum extent permitted by law, the authors of Summon are not liable for any damages arising from your use of, or inability to use, the extension. Since Summon stores nothing beyond your local settings and transmits nothing, the practical surface for harm is deliberately tiny.

Privacy

Summon collects no data at all. The full details — what it can access and why — are in the Privacy Policy.

Changes to these terms

If these terms change, the updated version will be published here with a new date at the top. Continued use of Summon after a change means you accept the updated terms.
