Terms of Service

Last updated: April 17, 2026

By texting Jar or otherwise using the service, you agree to these terms. Jar is operated by Rubric Labs and is provided on an as-is basis.

The service

Jar is a conversational AI assistant you interact with over SMS. It can answer questions, run tasks on your behalf, and send reminders you explicitly request. Message and data rates from your carrier may apply. Message frequency varies.

Opt-in and opt-out

• You opt in by texting our phone number first. We do not send unsolicited messages.
• Reply STOP at any time to opt out. Reply HELP for help.

Acceptable use

You agree not to use Jar to send unlawful, harassing, or abusive content, to attempt to bypass rate limits, or to probe, scan, or test the vulnerability of the system. We may suspend access for abuse.

AI-generated content

Jar's replies are produced by large language models. Output may be inaccurate, incomplete, or out of date. Do not rely on Jar for medical, legal, financial, or other professional advice. Verify important information before acting on it.

No warranty

The service is provided "as is", without warranties of any kind. To the maximum extent permitted by law, Rubric Labs disclaims all warranties and is not liable for indirect, incidental, or consequential damages arising from your use of the service.

Changes

We may update these terms as the product evolves. Continued use of the service after updates constitutes acceptance of the new terms.
