Terms of Use
Last updated November 8, 2026.
About this site
Tsumo is in development. This website exists to gauge interest and gather feedback. These terms cover using the site, joining the founding list and applying for the alpha test. The Privacy Notice explains how we handle your information.
What joining means
Joining the list or applying for the alpha test is free and puts you first in line for updates, pilot invitations and the chance to order. It isn't a purchase: before anything is sold, you'd see the final product, price and terms, and decide then. Features, specs and timing may change as we build.
Founding-member discount
If you join the founding list before launch and Tsumo launches, you can get 20% off the then-current standard subscription price for as long as you keep that subscription active, if you activate it within 90 days of launch. It does not apply to the wearable, other hardware or taxes. Final pricing and launch timing are not yet confirmed.
Not medical advice
Everything here is general information. Tsumo is not a medical device, has not been evaluated by the FDA, and does not provide medical advice, diagnosis or insulin dosing. Always follow your care team's guidance.
Concept images and films
Images are design renders and the films are made with AI video. They show the intended design, not a finished product.
The alpha test
Applying doesn't guarantee a spot. If you're invited, you'd get a separate agreement explaining the test, any device loan and how test data would be handled, and nothing starts until you accept it.
What you send us
You confirm you're 18 or older and that what you send is accurate and yours to share. If you share ideas or feedback, we may use them to improve Tsumo without owing you anything; your personal information is still handled as the Privacy Notice describes.
Our content
The Tsumo name, logo, text, images and films belong to Tsumo or are used with permission. Please ask before copying or reusing them.
Fair use of the site
Please don't misuse the site, interfere with how it works, send false or automated entries, or use it to break the law.
Limits
The site is provided as is. To the extent the law allows, Tsumo isn't liable for indirect or consequential losses from using it.
Changes and law
We may update these terms; the date above shows the current version. They're governed by the laws of Texas, USA. Questions: info@tsumoapp.com.
