Overview

Blood Snap is a free wellness logging app. Your health readings are personal. We do not sell your BP, glucose, or weight data. The app is supported by advertising (Google AdMob) on most screens; camera and voice logging flows do not show ads.

What we collect

Health data you enter

Blood pressure, blood sugar, and weight readings
Notes, meal context, medicine schedules, and reminder settings
Account email when you sign in (email, Google, or Apple)

On your device

Readings are stored locally so the app works offline. When you sign in, data syncs to Firebase (Google Cloud) under your account ID. You can delete your account and cloud data from Settings → Delete Account.

Camera / Snap entry

Snap entry uses your camera to photograph a monitor display. Blood Snap runs on-device OCR (Google ML Kit) first. When you allow Snap & voice AI parsing in the app, recognized OCR text from your monitor may be sent to Groq, Inc. to extract numbers. If parsing still fails, a cropped portion of the image may also be sent. You always review and confirm before anything is saved.

Voice entry

Voice logging uses on-device speech recognition. When you allow Snap & voice AI parsing, the transcript (not audio) is sent to Groq, Inc. to parse numbers into a log form. You review every value before saving. Transcripts are not kept beyond the request. If you decline, local regex parsing is used where possible.

Logging tips translation

When you allow Logging tips translation, educational how-to-log text (not your readings) may be sent to Groq so tips can appear in another language. Blood Snap does not generate health interpretation, diagnosis, or treatment advice.

Your permission

Before any personal data is sent to Groq, the app shows an in-app dialog explaining what is sent, who receives it, and asks for your permission. Privacy policy text alone is not sufficient — consent is collected in the app. You can manage consent in Settings → Privacy & AI.

Advertising (AdMob)

The free app shows ads through Google AdMob. AdMob may collect device identifiers and ad interaction data to serve and measure ads. Your health readings are not shared with advertisers for targeting. You can learn more in Google's Privacy Policy and ad settings on your device.

Website analytics

We use Google Tag Manager / Analytics on bloodsnap.com for anonymous site usage. This does not include app health readings.

Waitlist and email

If you previously joined our website waitlist for iOS launch, we collected your email only to notify you about the app. You can unsubscribe from any message we send. The app is now live on the App Store and Google Play — no waitlist is required to download.

How we use your data

To provide logging, history, charts, exports, reminders, and medicine tracking
To sync data across your devices when signed in
To parse voice or camera entries when you allow it (you review before save)
To show ads that support the free app
To send product emails you opted into

Blood Snap is a diary, not a monitor

Blood Snap logs numbers you type, speak, or confirm from a home blood pressure monitor, cuff, glucometer, glucose meter, or scale. It is not those devices and does not take a measurement itself.

Third-party services

Firebase (Google) — authentication and cloud database for signed-in users
Groq, Inc. — optional snap/voice parsing and Logging tips translation (only with in-app consent)
Google AdMob — in-app advertising
Google ML Kit — on-device OCR for snap entry (does not send images to Groq)
Resend — transactional website emails
Google Tag Manager / Analytics — website analytics only
