The short version

We keep this site simple. Your name and quest progress stay in your own browser unless you choose to join our follow-up list. We don't run ads, and we don't use analytics or tracking cookies. If you send us a message or join the list, we get what you type and use it to reply or follow up.

What stays on your device

When you add your name to the habit tracker or check in on a habit, your browser saves that information in its local storage. It isn't sent to us.

You can remove it any time by choosing “Not you?” or “Start a new sprint” in the tracker, or by clearing this site's data in your browser settings. If you use a different browser or device, you'll start fresh.

If you send us a message

The Get involved form asks for your name, who you are, your email and a message. It is collected with Google Forms, which stores the answers in a Google account run by the JanuHealth team.

We use it only to reply to you and to understand who is interested in JanuHealth. We don't sell it or share it with advertisers. You can ask us to delete your message at any time.

If you join the follow-up list

After the Hidden Sugar Lab or on the habit tracker, you can choose to join our follow-up list. Nothing is sent unless you tick the box and press the button.

We collect your first name, email, grade, and a short note about what you tried (for example your lab guess, or how many days of your quest you finished). We use it to check in on how you are taking care of yourself, to understand how well JanuHealth works, and to send you swag. We don't sell it or share it with advertisers.

The answers are collected with Google Forms. You can ask us to remove you at any time and we will delete your details.

Cookies and tracking

This site doesn't use advertising or tracking cookies, and we don't run analytics. If that changes, we'll update this page first.

Hosting and fonts

Our pages are hosted by Cloudflare. Like most hosts, Cloudflare may log technical details such as your IP address to keep the site secure and running.

We also load our fonts from Google Fonts, so your browser contacts Google's servers to download them.

Students under 18

If you're under 18, ask a parent, guardian or teacher before you send us your email address. Students in Grades 5 to 8 need a parent or guardian's OK to join the follow-up list, and a parent or guardian's email is best. You can use the habit tracker and the sugar lab without sharing any contact details at all.

Questions or deletion requests

Send us a note through the Get involved page and we'll help.
