BenOS
Terms of service
Last updated: 3 October 2026
These terms cover your use of the BenOS app and this website. BenOS is made by Ben Galbraith ("we"). By installing or using BenOS, you agree to them.
Early access
BenOS is an early release, offered free of charge by invitation. It may have bugs, change or stop working, and we may stop offering it at any time. Keep your own copies of anything that matters to you. BenOS copies your data, but it isn't a backup of the services it reads from.
Your licence
We give you a personal, non-exclusive, non-transferable licence to install and use BenOS on Macs you own or control, for your own use. Don't redistribute, resell or reverse engineer it, except where the law lets you regardless of these terms.
Your data and your accounts
- Your data stays yours. BenOS keeps it on your Mac, as described in the privacy policy, and we don't receive it.
- You're responsible for the accounts you connect, and for following the terms of the services you add: for example Google's, WhatsApp's and your AI provider's. BenOS connects to WhatsApp through an independent client, not one made by WhatsApp. WhatsApp may not allow such clients, and may restrict accounts that use them.
- Only connect accounts and data that you're entitled to use. Messages and email include other people's words; use them with the same care you would anywhere else.
Your agent
BenOS lets an AI agent you choose read your library and, when you allow it, make changes in services such as Gmail and Google Calendar on your behalf. You're responsible for the agents you connect and for the changes they make. BenOS records those changes and asks for your approval before ones that can't be undone, but AI agents make mistakes: review what they do.
No warranty
BenOS is provided "as is" and "as available", without warranties of any kind, express or implied, including fitness for a particular purpose and non-infringement, to the extent the law allows.
Limitation of liability
To the extent the law allows, we aren't liable for any indirect, incidental, special or consequential loss, or for loss of data, arising from your use of BenOS. Our total liability for anything relating to BenOS is limited to £50. Nothing in these terms limits liability that can't be limited by law.
Ending
You can stop using BenOS at any time by deleting the app and its benos
folder. We may end your licence if you break these terms.
Changes
We may update these terms. If a change matters, we'll update the date at the top and say so in the release notes. Continuing to use BenOS after a change means you accept it.
Law
These terms are governed by the laws of England and Wales.
