Terms of service

Last updated November 10, 2026

Ten4 is a task manager that works with your AI assistant. Anyone can sign up with an email address. By signing up, signing in or connecting an assistant to it, you agree to these terms. If you don't, please don't use it.

Your account

• Signing up with your email address creates your account. The person who runs this deployment can remove accounts.
• Sign-in is a code emailed to you. Keep your email account and any assistant you connect to Ten4 under your own control; what they do in your name is on you.
• Don't share your access or try to reach anyone else's work.

Beta and pricing

Ten4 is in beta: expect bugs, changes and downtime, and don't depend on it yet. It is free while it is in beta. When it launches, it is planned to cost $5 per month. Nothing is charged now, and no payment details are collected.

Your content

What you put in Ten4 stays yours: your tasks, notes, drafts and checklists. You give Ten4 permission to store and show it to you, and to the people on a team you share, so that it can work. Don't put in anything you don't have the right to store, and don't store anything unlawful.

Working with an AI assistant

Ten4 is built to be used through an AI assistant, and the assistant writes much of what Ten4 holds: descriptions, prompts, briefs, email drafts, checklists and the morning edition. That writing can be wrong, so read it before you rely on it. Ten4 never sends an email draft for you, and it never calls an AI model itself; you send, run or act on what it produces. Your use of an assistant is also subject to that provider's own terms.

Connected services

If you connect Google Calendar, Ten4 can read the calendars you choose and create time blocks you ask for. You can remove that access at any time at myaccount.google.com/permissions. The services Ten4 runs on (hosting, database, email, Google) are subject to their own terms and can have outages that Ten4 can't prevent.

Acceptable use

Don't use Ten4 to break the law, to harass or deceive anyone, to send spam, to probe or disrupt the service or its security, or to put an unreasonable load on it.

No guarantees

Ten4 is provided as is and as available, with no promise that it will be uninterrupted, error-free or kept forever, and no warranty of any kind. It isn't a place to keep the only copy of anything important, and you shouldn't rely on it for anything where a missed reminder, a wrong draft or a lost task would cause serious harm. Keep your own backups of what matters.

Limits on responsibility

To the fullest extent the law allows, the person who runs Ten4 isn't liable for indirect or consequential losses, or for lost data, time or opportunities, arising from your use of it. Nothing here limits a responsibility that the law doesn't allow to be limited.

Ending your use

You can stop using Ten4 at any time and ask to have your account and its contents deleted, by contacting the person who runs this deployment. Access can be suspended or removed if these terms are broken or the service is shut down. What happens to your data is described in the privacy policy.

Changes

These terms may change. When they do, the date at the top will change, and continuing to use Ten4 means you accept the new version.
