Terms of service

Plain terms. Honest limits.

Effective 13 November 2026 · Octag AI LLC · hello@signmog.com

SignMog is an aid, not a certified interpreter. For medical, legal, school, work and emergency needs, ask for a qualified interpreter.

1. The agreement

These terms are a contract between you and Octag AI LLC ("we") for the SignMog website, the web app and the Chrome extension (together, "SignMog"). By using SignMog you accept them. If you do not agree, do not use SignMog. The privacy policy explains what reaches us and what does not, and is part of these terms.

2. An aid, not a certified interpreter

SignMog is an aid, not a certified interpreter. It turns speech, text and captions into American Sign Language signed by a 3D signer, and reads signing back through the camera. It helps in everyday moments. It does not replace a qualified human interpreter.

• It can be wrong. A sign can be wrong, unclear, or not how a community signs it. Long sentences can come out closer to English word order than to natural ASL. Speech recognition can mishear. Sign to Speech can misread a sign or miss one. Check anything that matters.
• Draft until verified. Signs are reviewed by fluent signers before they are marked verified. Many signs have not been reviewed yet. Treat a sign that is not verified as a draft.
• Not for high stakes. Do not use SignMog as the only way to communicate in medical, legal, court, school, work, safety or emergency situations. Ask for a qualified interpreter. In many places you have a right to one.
• In an emergency, contact your local emergency service directly, by the means it offers, such as a call, text or relay service.
• Not while driving. Do not use SignMog in a way that takes your eyes or hands from driving or from running machinery.

3. Who can use SignMog

Anyone can use the free app, with no account. If you are under 13, use SignMog with a parent, guardian or teacher nearby, and ask them to send any report or email for you. If you use SignMog for an organization, such as a school or a business, you accept these terms for that organization too.

4. Free and Pro

Free

Free costs nothing: live speech to sign, type to sign, sign to speech through the camera, the dictionary with slow motion and orbit, Learn with its lessons and quizzes, both twins, and the Chrome extension side panel. Free runs on your device and needs no account. We may add to it, change it, or ask you to try new features, and we will say on the home page before we take away anything Free includes today.

Pro

Pro is coming soon, with Cloud grammar and meeting captions. It has no price yet and cannot be bought. Before Pro opens, its price, what it includes, how to cancel and how refunds work will be shown on signmog.com and at checkout, and those terms will be added here before anyone is charged.

5. The Chrome extension

The extension signs captions that a web page shows as text, in a side panel next to the page: by itself on YouTube, Google Meet, Zoom and Teams on the web, and on other pages when you click Read this page. The privacy policy says exactly what it reads. The captions belong to whoever published them. Use the extension only with content you are allowed to watch, and do not use it to copy, record or republish someone else's captions or videos. Until the Chrome Web Store listing is live, the extension is offered as an early build that you add by hand, and it may change without notice.

6. Your reports and our content

American Sign Language belongs to the Deaf community. We claim no ownership of the language. What we own is our software, our 3D signers and the way we recorded each sign.

Your reports. When you report a sign or send us feedback, you let us use it to review and improve SignMog's signs, for free and without owing you anything. Please do not include other people's private information.

Our content. The software, the sign recipes in the dictionary, the lessons, the twins Sig and Sia, the SignMog mark and the SignMog name are ours or our licensors'. You may use them to communicate, to learn and to teach, including in a classroom. You may not copy the dictionary or the twins into another product.

7. Fair use

Use SignMog to communicate and to learn. Do not:

• point the camera at people who have not agreed to it, or use the microphone to listen to people without telling them;
• present SignMog as a certified or human interpreter, or charge others for "interpreting" done with it;
• use SignMog to mock Deaf people or sign language, or to sign content that is illegal, hateful or harassing;
• use bots or scripts to scrape, overload or probe SignMog, or to copy the dictionary;
• try to get around Pro's limits when it opens, or share, sell or rent Pro access.

We may block access that does, and report illegal activity.

8. Other companies' services

Speech recognition and the voice that speaks for you come from your browser. The hand tracker and other open-source code are served by jsDelivr and Google. The extension works on YouTube, Google Meet, Zoom and Microsoft Teams, which are not affiliated with SignMog, and will be distributed through the Chrome Web Store. These services have their own terms and policies, and they may change or end their support at any time. We are not responsible for them.

9. Changes to the service and to these terms

We improve SignMog all the time and may add, change or retire features and signs. If we change these terms in a way that affects your rights, we update the date at the top and say so on the home page before the change applies. Using SignMog after that means you accept the new terms. Once Pro opens, we will also tell Pro members by email.

10. Warranties and liability

SignMog is provided "as is" and "as available". Its signs, its reading of your signing and its speech recognition are produced by software and can be wrong or incomplete. We do not promise that SignMog will be uninterrupted or error-free, or that anyone will understand or be understood correctly through it. You are responsible for how you use it, and for asking for a qualified interpreter when the situation needs one.

To the extent the law allows, we exclude implied warranties and are not liable for indirect, incidental or consequential loss, or for lost data or profit. Our total liability for claims connected with SignMog is limited to the amount you paid us in the twelve months before the claim, or 50 US dollars if you paid nothing. Nothing in these terms limits liability that the law does not allow us to limit, including for fraud or for death or personal injury caused by negligence.

11. Ending the agreement

You can stop using SignMog at any time: close the app, remove the extension, and clear the site's data in your browser. We can block access for anyone who breaks these terms. Sections 2, 6, 10, 12 and 13 survive the end of the agreement.

12. Governing law and disputes

These terms are governed by the laws of the State of Florida and the federal laws of the United States, without regard to conflict-of-law rules. Disputes are heard in the state or federal courts located in Florida, except that consumers in the European Economic Area, the United Kingdom and Switzerland keep the protection of the mandatory laws and courts of their home country. Before going to court, email us and give us 30 days to put things right.

13. Everything else

These terms and the privacy policy are the whole agreement between us about SignMog. If a part is unenforceable, the rest stays in force. We may assign the agreement as part of a sale of the business; you may not assign it. Notices to us go to hello@signmog.com. Google is not a party to these terms and has no obligation to support the extension.
