Privacy notice
Tsumo is in development. This website is here to gauge interest and gather feedback. This notice covers the website only, not any future Tsumo device or app.
Last updated October 29, 2026. Tsumo, Houston, TX. Contact: info@tsumoapp.com.
What we collect
If you join the list: your email, your plan choice and your 18+ and contact confirmation. If you choose to add them: your first name, how you'd wear it, whether you're open to a call, and, in the optional section, who you're signing up as (for example Type 1, or parent of a child with diabetes) and what would help most. We also save when you agreed and to which version of this notice, and, if you came from a tagged link, its campaign labels (like "reddit").
If you apply for the alpha test: your email, your 18+ and contact confirmation and whether you could test for two weeks, plus, if you add them, your first name, city and state, phone type and the devices you use today (which can be health information, so it has its own box).
If you share your story: the story itself (which may include health details), your confirmation that you're 18 or older and agree to its use, and, if you add them, your first name and email. We won't publish or quote it without asking you first.
If you contact us: your email, your message and topic, your 18+ and reply confirmation, and, if you add them, your first name and organization.
If you answer the one-question survey after joining: your answer and the plan you picked, without your name or email.
We don't ask for a child's name or contact details, medications, glucose readings, photos or medical records.
Why
To run the founding list and the alpha test, to read the stories you share, to email you about this research and when Tsumo is ready, and, if you shared the optional answers, to understand who Tsumo could help.
Who handles it
Netlify hosts this site and stores sign-ups, and its spam filter (Akismet) may check form submissions. Like any web host, it processes technical data such as your IP address to deliver the page. Google Workspace runs our email at info@tsumoapp.com, including the notifications we receive when you send a form. Fonts, scripts, images and videos are served from this site itself, not from outside services.
Netlify's built-in analytics counts visits from its own server records, without cookies or tracking scripts: which pages were visited and roughly where visitors came from. We don't send it anything you type.
Google Analytics runs only if you click Accept, and only on the public pages, never on the sign-up, alpha, contact or story pages. It counts visits and clicks. It doesn't receive your name, email or anything you type in the form, and its advertising features are off. This site has no advertising pixels.
Cookies
This site sets no cookies unless you accept Google Analytics. While you browse, your browser also keeps a few small notes that clear when you close the tab: the campaign label of the link you came from, the plan you picked, and whether you just signed up. If your browser sends a Global Privacy Control signal, we treat it as a no to analytics. Your choice is remembered in your browser, and you can change it anytime with "Privacy settings" at the bottom of the page.
How long we keep it
Up to 24 months after you sign up, unless you ask us to delete it sooner. Before then, we'll ask if you'd like to stay on the list.
Your choices
Write to info@tsumoapp.com to see, correct or delete what you sent, to withdraw a consent, to ask which companies received it, or to leave the list. We'll delete it from Netlify and anywhere else we've kept a copy, and confirm when it's done. Copies in our providers' backups expire on their own schedules. Depending on where you live, including Washington, you may have extra rights over health-related information; write to us to use them.
Consumer health data
The optional answers about diabetes (including that you're the parent of a child with diabetes), the devices you list on the alpha form, and the stories you share can be health information. We collect them only if you answer and tick their own box, use them only to understand who Tsumo could help, keep them with the rest of your sign-up in Netlify, and don't sell or share them for advertising. You can withdraw that consent anytime at info@tsumoapp.com and we'll delete those answers.
