Privacy by architecture
"We don't sell your data" is a promise. How an app is built is a guarantee. SteadyRange is designed so that understanding your numbers never means handing them over.
Analysis runs in the app, not in a data lake
Your insights, your weekly briefing, your note tags, your time-in-range: every pattern is computed by plain functions inside the app, on your data alone. There is no ad-network pixel, no cookie-based tracker, and no model in the loop reading your numbers. Our hosting platform counts page visits in aggregate (cookieless and anonymized, never your readings) so we can tell which pages help. Turning a reading into meaning never requires sending it anywhere.
Your readings live in your own database
SteadyRange keeps your glucose and BMI history in a database scoped to your account, not pooled into a shared dataset mined across users. Every query that touches a reading is filtered to your user ID, so one account can never see another's data.
We don't sell, share, or train on your data
Your health data is not a product. We don't sell it, we don't hand it to advertisers, and we don't use it to train models. The report you generate for your doctor is built on the fly and handed to you, not retained for anyone else.
You can take it or erase it, anytime
Export a full backup whenever you like, or erase every reading and record in one click: your settings stay, your data goes. There is no retention you can't reverse and no lock-in: your history is yours to move.
The one exception, stated plainly
Everything above holds for every feature in the app today. Anything that would ever send data off your device (like reading a lab photo with AI) will always be opt-in and labeled as such, never the default.
This page describes how the product is built; it isn't legal or medical advice. Learn the terms behind your numbers in the glossary.
