Terms & Conditions
Last updated: September 10, 2026
These Terms & Conditions (“Terms”) govern your use of Lemongraph (the “Service”). By accessing the Service or signing in with Google you agree to these Terms. If you do not agree, do not use the Service.
Eligibility
You must be at least 13 years old and able to form a binding contract to use the Service. By using it you confirm that you meet these requirements.
Accounts and sign in
Authentication runs through Google sign in. You are responsible for maintaining the security of your Google account and for all activity that happens under your account. Report any unauthorized use straight away, at the address below.
What the Service does on your behalf
Lemongraph runs agents that pursue work for you over days or weeks. To carry that work forward they act in your Google account: sending mail as you, applying labels, archiving messages, and creating, updating and cancelling calendar events. You are responsible for what your agents do under your account, in the same way you are responsible for mail you send yourself.
Agents are software and they get things wrong. Review the work that matters before it goes out. You can require your approval before an agent takes an action, and leaving that on for anything that leaves your account is the safer setting.
Your data
You keep ownership of your mail, your calendar and everything else you bring to the Service. That data runs the Service for you and serves nothing else. What gets collected and who processes it is set out in the Privacy Policy and the sub-processor list. What the Service can and cannot reach in your Google account is set out on the security page.
Your data is never sold, and no provider is permitted to train generalized models on it.
Acceptable use
You agree not to:
- Use the Service for any unlawful or harmful purpose.
- Attempt to gain unauthorized access to the systems behind the Service or to data held in them.
- Interfere with or disrupt the Service or its infrastructure.
- Reverse engineer or copy the Service except as permitted by law.
Intellectual property
The Service, including its content and software, belongs to Lemongraph and is protected by intellectual property laws. Using the Service for its intended purpose is a limited, non-exclusive, non-transferable right granted to you.
Third party services
The Service relies on third party services such as Google. Your use of those services is governed by their own terms and policies, which sit outside the responsibility of Lemongraph.
Disclaimer of warranties
The Service is provided “as is” and “as available” without warranties of any kind, whether express or implied. There is no warranty that the Service will be uninterrupted, secure or error free.
Limitation of liability
To the maximum extent permitted by law, Lemongraph is not liable for any indirect, incidental, special or consequential damages arising from your use of the Service. Total liability is limited to the amount you paid, if any, in the 12 months before the claim.
Termination
Access to the Service may be suspended or terminated at any time if you violate these Terms.
You can leave at any time. Revoking access in your Google account stops agents immediately, and deleting your account from Settings erases your data on the timeline described in the Privacy Policy. Deletion is not reversible, so export anything you want to keep first.
Changes to these Terms
These Terms may change from time to time. The new version is posted on this page with the date above updated. Continued use of the Service after changes means you accept the revised Terms.
