Mentomo terms of service
Last updated: November 10, 2026
These terms are an agreement between you and Kaminsky Data Strategies, LLC (“we”), which runs Mentomo. By using the Mentomo app or website, you agree to them. Our privacy policy explains how we handle your data.
Mentomo is in beta
Mentomo is free and by invitation while we build it. Features may change, break or go away, and we may pause or end the service. If we end it, we’ll try to tell you first so you can ask for a copy of your writing.
Who can use Mentomo
You must be at least 13 years old. If you’re under 18, you need a parent’s or guardian’s permission. Use Mentomo only for your own language learning.
Your account
You sign in with codes sent to your email or phone, so keep those secure. You’re responsible for what happens in your account. If you think someone else got in, write to us.
Tomo is an AI coach
Tomo’s corrections, explanations, translations and grades come from AI models and can be wrong. Use your own judgment, and don’t rely on Mentomo for anything important, such as legal, medical or official translations.
Your writing
What you write stays yours. You give us permission to store, copy, process and display it as needed to run Mentomo for you, and to test and improve Tomo as our privacy policy describes. This permission is worldwide and free of charge, and it ends when your writing is deleted, except for examples we keep under the privacy policy. Don’t write anything you don’t have the right to share.
You may use Tomo’s corrections and replies however you like. If you send us feedback or ideas, we may use them without owing you anything.
What you may not do
- break the law, or use Mentomo to harass, threaten or harm anyone;
- try to get into other people’s accounts or into our systems, or interfere with how Mentomo works;
- use bots, scripts or other automated means to access Mentomo, or use it in ways meant to run up its costs;
- try to make Tomo produce harmful content, or use Tomo for anything other than learning;
- copy, resell or reverse engineer Mentomo.
Ending your use
You can stop using Mentomo at any time and ask us to delete your account, as our privacy policy explains. We may suspend or close your account if you break these terms, if it’s needed to protect Mentomo or other people, or if we end the service.
Our content
Mentomo’s software, design, word lists, exercises and the character Tomo belong to us. We give you a personal, non-transferable permission to use them for your own learning while you use Mentomo.
No guarantees
Mentomo is provided “as is” and “as available.” To the extent the law allows, we make no promises about it, express or implied, including that it will be accurate, uninterrupted or error-free, or that your data will never be lost.
Limits on our liability
To the extent the law allows, we aren’t liable for indirect, incidental, special, consequential or punitive damages, or for lost data, profits or opportunities, arising from your use of Mentomo. Our total liability for any claim is limited to the greater of what you paid us in the 12 months before the claim and US$50.
Some places don’t allow these limits. Nothing in these terms takes away rights you have under consumer protection laws that can’t be waived.
Governing law
These terms are governed by the laws of Texas, United States, and disputes go to the courts in Dallas County, Texas, unless the law where you live gives you the right to use its laws or courts.
Changes
We may update these terms from time to time. We’ll post the new version here with its date. If a change is material, we’ll let you know in a reasonable way, such as a notice on our site or in the app, before it applies. If you keep using Mentomo after a change applies, you accept the new terms.
