No. SnapVitals is a consumer wellness tool, not a medical device. It does not diagnose, treat, cure, or prevent any condition. Always consult your doctor for medical decisions.

On your Android device. Readings, photos, and family profiles do not leave your device unless you explicitly choose to share or export them. SnapVitals does not require an account.

Tap the value on the result screen to correct it before saving. Automatic recognition can be affected by glare, low light, or unusual monitor models — please verify every scanned value against your monitor before saving.

Open Settings → Export readings to share readings as a PDF or CSV file. Open Settings → Backup & restore to create a complete backup file. In both cases Android will show the Share sheet (or the Storage Access Framework save picker) where you can save the file to a destination you choose — local storage, Google Drive, email, Files by Google, or any other document provider or share target.

Android Auto Backup is a default Android platform service that automatically copies a small set of app data (your readings database and your in-app settings) to your own private Google Drive backup folder, so SnapVitals can restore your data when you reinstall on the same Google account. Photos, anonymous identifiers, and temporary scan files are excluded from Auto Backup. We do not have access to this data — only you do, through your Google account.

To turn Auto Backup on or off, open Android Settings → System → Backup. To delete an existing backup, open the Google One app → Storage → Device backups → SnapVitals → Delete. Exact menu names may vary by Android version and Google Play services version.

Delete individual readings or family profiles directly in the app. To remove all on-device data, uninstall SnapVitals from your Android device. If you had Android Auto Backup enabled (Android's default), a private backup copy lives in your Google Drive — delete it from the Google One app under Storage → Device backups → SnapVitals → Delete. To request deletion of any feedback content you previously submitted, email us using the address at the bottom of this page.

Yes. Scanning, manual entry, history, trends, and exports all work fully offline. An internet connection is needed only when you submit feedback, or when anonymous usage events are sent to our servers (see Privacy Policy §1 and §4 for what those events contain and how to opt out).

To improve the app, we record events such as "app opened" or "scan attempted" along with a randomly generated anonymous device identifier and your Android / app version. These events do not contain your name, email, location, blood pressure values, photos, or any health data — only counts of which app features get used. They are sent only to our own servers and are not shared with any third party. See the Privacy Policy §4 for retention details.

SnapVitals categorizes readings using the 2025 ACC/AHA Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults. These ranges are general references and are not a substitute for your clinician's individualized targets.

If your readings remain outside your usual range, or if you experience symptoms such as dizziness, persistent headache, chest discomfort, blurred vision, or weakness. If your systolic reading is 180 mmHg or higher, or your diastolic reading is 120 mmHg or higher, wait five minutes and measure again; if still this high, contact your doctor immediately. Call 911 if you also have chest pain, shortness of breath, numbness, vision changes, or trouble speaking.
