Terms of service

These terms are an agreement between you and Mum AI SA, a Swiss company (“Mum”, “we”, “us”). By using Mum, in Signal or at mum.ai, you agree to them. Our Privacy policy explains what we keep, what we never collect, and how the sealed hardware works.

You need a Signal account to use Mum, and Signal’s own terms apply to your use of Signal. You must be at least 18 to use Mum.

Your Mum is tied to your Signal account. We don’t ask for your name or email. Anyone who can send messages from your Signal account can use your Mum, so keep your phone and Signal locked. If you lose access to your Signal account, write to hi@mum.ai.

Mum is an AI assistant you talk to in Signal. It can answer questions, research, plan, and use websites for you to compare, book and buy things.

You can add Mum to group chats, where it responds when someone mentions @mum. Your Mum can also work with other people’s Mums for you.

A token is a small piece of text, roughly three-quarters of a word. Mum counts tokens for everything it reads and writes for you, including web pages it reads while working on a task. The allowance resets every week. When you reach it, Mum tells you and waits until the next week. Paid plans are coming later; their prices, billing and refund terms will be shown before you pay and added here.

If you save a card for Mum to use, Mum can pay for things with it, but only after you say yes to each payment in the chat. If you say no, nothing is charged.

You’re responsible for the payments you approve. Purchases are between you and the seller, so the seller’s terms, refund and cancellation policies apply.

When you ask Mum to use a website, sign up or book for you, it does so on your behalf, and that website’s terms apply to you as if you’d done it yourself.

Websites can block automated visits or change how they work without notice, so we can’t promise every task will succeed.

When you ask Mum to call or email someone for you, it does so on your behalf. Only ask Mum to contact people you’re allowed to contact.

Don’t use Mum to:

• break the law, or buy anything you’re not allowed to buy;
• harass, threaten, deceive or harm anyone;
• get into accounts, systems or data you’re not allowed to access;
• send spam or run scams;
• attack or try to break into Mum’s sealed computers. If you find a security problem, tell us at hi@mum.ai.

Mum is built so we can’t read your conversations. Your chats end inside sealed hardware that nobody can open, the sealed computers keep no logs anyone can read, and Mum never trains on what you say.

• Replies, voice, reading files and pictures, sorting your email and dreams all run on sealed AI hardware.

Browsing with Mum is private, and the AI that steers its browser isn’t told who you are. The Privacy policy has the details, and How Mum works explains the hardware.

Mum’s answers are written by AI and can be wrong or out of date. Check anything important before you rely on it.

Mum isn’t a doctor, lawyer or financial adviser, and its answers aren’t professional advice.

Some place and travel results use Google Maps content. Your use of it is subject to the Google Maps/Google Earth Additional Terms of Service (https://maps.google.com/help/terms_maps/) and Google’s Privacy Policy (https://policies.google.com/privacy).

Every new version of the software in Mum’s sealed computers has its fingerprint recorded in a public transparency log before it can receive any keys, so a version that isn’t on record can’t get them.

If we change these terms, we’ll post the new version here with a new date and tell you in your chat with Mum before the change takes effect.

You can stop using Mum at any time, and you can have your account deleted (the Privacy policy says what is deleted and the little that is kept). We may suspend or close accounts that break these terms.

We work hard to keep Mum running and private, but Mum is provided as it is and as available, and we can’t promise it will always be available or free of errors.

As far as the law allows, we aren’t liable for indirect or consequential losses, and our total liability to you is limited to what you paid us for Mum in the 12 months before the claim. Nothing in these terms limits liability that the law doesn’t allow us to limit, or rights you have as a consumer that can’t be waived.

These terms are governed by Swiss law. Disputes go to the competent courts in Switzerland. If you’re a consumer, this doesn’t take away the protection of the mandatory laws of the place where you live, or your right to bring a claim in your local courts where those laws give you one.

Questions about these terms are welcome at hi@mum.ai.
