SteadyPrivacy Policy
Effective November 14, 2026
This policy explains what the Steady app and this website do with your information. Steady is made by Trần Văn Bình ("we"). Questions go to support@docusmarter.com.
Data that stays on your phone
Steady works without an account. Your blood pressure readings, pulse, notes, medicines, dose times, what you took or skipped, the people you track and your settings are stored in a database on your device. We cannot see them. Reminders are scheduled on your device.
Your phone's own backup (iCloud or Google) includes Steady's data under your Apple or Google account, following your phone's settings. Backup files, CSV exports and doctor reports are files you create, and they go only where you choose to save or send them.
Data that leaves your phone
Only these features send data off your device. Each one is something you choose to use, and all of it is encrypted in transit.
- Scanning a monitor or a medicine label. Steady asks before your first scan. The photo you take is sent through Google Firebase AI Logic to Google's Gemini AI model, which reads the numbers or the label and sends the text back. Steady does not store the photo. Google processes it under the Gemini API terms. To stop, do not use the scan buttons; typing works the same.
- Family sharing. If you share, an anonymous sign-in is created and your phone publishes a summary for the people you invite: your name as you entered it, today's medicines with their times and whether each was taken, and, if you allow it, your latest reading, your 7-day average and your on-time rate over 30 days. You choose whether medicines and blood pressure are included. Our server checks the times of unmarked doses and sends your family a notification when one is missed; it keeps a record of sent alerts for three days. Family members who join give a name, which you see, and a notification token so their phone can receive alerts. Stop sharing deletes your summary; a family member can leave at any time.
- App Check. To keep others from misusing the scanning and family services, the app proves it is the real Steady app using Apple App Attest or Google Play Integrity. This sends a device attestation, not your health data.
Apple Health and Health Connect
If you turn it on, Steady reads blood pressure readings from Apple Health or Health Connect and saves the readings you type there. This happens on your phone, with the permissions you grant, and you can turn it off in your phone's settings. Health data is never used for advertising or shared with us.
Purchases
Apple and Google process all purchases. We never receive your payment details. The app checks your purchase status on your device to unlock Steady Pro.
What we do not do
- We do not sell or rent your data, or share it for advertising.
- We do not show ads, and the app has no analytics, tracking or crash reporting tools.
- We do not ask for your email, phone number or location.
Service providers
We use Google Firebase (AI Logic with Gemini, Authentication, Cloud Firestore, Cloud Functions, Cloud Messaging and App Check) for the optional features above, Apple and Google for purchases, health data on your phone and notifications, and Cloudflare to host this website. They process data only to provide these services, under their own privacy terms.
This website
This website sets no cookies and uses no analytics. Fonts and images are served from this site. Our host, Cloudflare, processes technical data such as your IP address to deliver and protect the site. The reading check on the home page runs in your browser, and what you type is not sent anywhere.
How long we keep data
A shared family summary is kept until you stop sharing, and is replaced each time your phone updates it. Records of sent alerts are kept for three days. Scan photos are not kept by Steady. If you email us, we keep the message as long as we need it to help you.
Your choices and rights
- Delete data on your phone: delete readings or medicines in the app, or delete the app. Backup files you saved are yours to delete.
- Delete shared data: in Steady, open Settings, then Share with family, and choose Stop sharing. Or email us and we will delete it.
- Access or correct your data: most of it is in the app. For anything else, email us.
Depending on where you live, including California and the EU, you may have rights to access, correct, delete or port your personal data, and to complain to a regulator. Email us to use them. We will not treat you differently for doing so.
Children
Steady is made for adults and is not directed at children. If you believe a child has given us personal data, contact us and we will delete it.
Changes
If this policy changes, we will update this page and the effective date.
