Duet Terms of Service
The terms for using Duet, the private SMS assistant run for one household.
Last updated: August 21, 2026
What Duet is
Duet is a private, invite-only SMS assistant used by a single household. Today that household is the operator and his partner. There is no public sign-up. The operator is Joe Cohen, and he runs the service himself.
By texting the assistant after the operator adds your number, you agree to these terms.
Who can use it
Only members the operator has added to the service configuration can use Duet. Enrollment takes two steps: the operator adds your mobile number by hand, and you text the assistant from your own phone.
Permitted use
Duet is for personal household use by enrolled members. While using it, do not:
- ·Share or resell access to the service.
- ·Use it to send anything unlawful, abusive, or harassing.
- ·Use it for commercial messaging, marketing, or bulk sending of any kind.
- ·Try to enroll a number you do not control.
The operator may remove a member from the service for any of the above.
Messaging terms
The assistant replies when an enrolled member texts it, and sends one summary message a week. Message frequency is low and conversational.
Message and data rates may apply. Reply STOP at any time to opt out. Reply HELP for help.
Replying STOP ends the messages to that number. To start again, ask the operator to re-enroll you and text the assistant.
No warranty
Duet is provided as is, with no warranty of any kind. The operator does not guarantee that the service will be available, that messages will arrive, that saved notes will be kept intact, or that any answer the assistant gives is correct.
Replies come from an AI model and can be wrong. Do not rely on Duet for anything urgent, medical, legal, financial, or safety related. Keep your own copy of anything you cannot afford to lose.
Limitation of liability
To the extent the law allows, the operator is not liable for any loss or damage that comes from using Duet, including lost messages, lost notes, missed reminders, or a wrong answer from the assistant.
Changes and discontinuation
The operator may change, suspend, or discontinue Duet at any time, with or without notice. These terms can change too. The date at the top of the page shows when they last changed.
Privacy
The Duet Privacy Policy covers what the service collects and who processes it. It also states that no mobile information is shared with third parties or affiliates for marketing or promotional purposes.
