Privacy Policy

Overview

Blood Snap is a free wellness logging app with an optional Blood Snap Pro subscription. The free core diary covers blood pressure and blood sugar (Home, History, Insights) with unlimited manual logging, 1 snap and 1 voice entry per day. More Health tools — weight, water, sleep, manual steps, medicines (up to 2), and scanned documents (up to 5) — are free to log and view, with Analytics windows of 3, 7, or 30 days. Optional health metrics (steps, sleep, resting heart rate) can be switched on in More Health and read from Apple Health or Google Health Connect when you grant permission. Blood Snap Pro unlocks unlimited snap and voice with AI parsing, unlimited medicines with label scan, unlimited scanned documents with search inside their text, PDF/CSV export, cloud sync of diary readings, and two-way Apple Health / Health Connect sync. Blood Snap shows no advertising and includes no advertising SDK. Your health readings, More Health logs, medicines, and scanned documents are personal. We do not sell your BP, glucose, weight, water, sleep, steps, medicine, or document data.

Some optional features send limited data to a third-party AI service, Groq, Inc., and only after you tap Allow in the app. Optional Pro health sync can read and write readings with Apple Health on iPhone or Google Health Connect on Android, and only after you turn sync on in Settings → Health & data and grant the system permission. Sync stays off until you opt in. Document Vault files and folders stay on your device and are never part of cloud sync or Groq.

What we collect

Health data you enter

• Core diary: blood pressure (systolic, diastolic, and pulse), blood sugar, notes, and meal context
• More Health logs: weight; water intake (amount in glasses or millilitres, daily goal, timestamps); sleep you type yourself (start/end or duration and date); steps you type yourself (daily total and date)
• Medicines: name, dosage, purpose, instructions, schedules, dose logs (taken / skipped), adherence display, and reminder settings
• Optional profile: name, age or date of birth, gender, height (for BMI on the weight screen), and a weight goal
• Account: email when you sign in (email, Google, or Apple)
• Preferences you set: units, theme, dashboard layout, which More Health cards show on Home, reminder times, and personal threshold alerts you choose

You type these values, speak them, or confirm a suggestion from a photo. Blood Snap does not measure blood pressure, glucose, weight, steps, sleep, or heart rate itself. Resting heart rate and Health-sourced steps/sleep appear only when you switch those metrics on and grant Health permission.

On your device vs in the cloud

Everything starts on your device so the app works offline.

• May sync to Firebase (Google Cloud) when you are signed in and Pro cloud sync is available: blood pressure, blood sugar, weight, and medicine details under your account ID.
• Stay on this device only (not uploaded to Blood Snap / Firebase): water logs, manual sleep entries, manual steps entries, Document Vault PDFs, folder names, document names, tags, and on-device recognised text. Medicine label photos and voice audio are not stored in your account.

You can delete your account and cloud data from Settings → Delete Account. Deleting the app removes on-device-only data from that phone.

Camera / Snap entry

Snap entry uses your camera to photograph a home monitor display. How it is collected: you take the photo in the app. Blood Snap runs on-device text recognition (Google ML Kit) on the device first. When you allow Snap & voice AI parsing, the recognized text may be sent to Groq, Inc. to extract numbers. If that still fails, a cropped portion of the monitor image may also be sent to Groq, Inc. for the same purpose. You always review and confirm before anything is saved. If you tap Not now, the photo is not sent and a local fallback is used where possible.

Medicine label scan

You can photograph a medicine box, bottle, or blister to pre-fill a medicine. How it is collected: you take the photo in the app, then on-device text recognition (Google ML Kit) runs on the device. When you allow Medicine label scan, the photo and the recognized text are sent to Groq, Inc. to suggest the name, dosage, purpose, and instructions. You review and edit every field before it is saved. The photo is used for that request only and is not saved to your Blood Snap account. If you tap Not now, only on-device text recognition is used and the photo is not sent to Groq.

Document Vault — files, folders, and tags

Document Vault (More Health → Documents) lets you scan paper documents such as lab reports, prescriptions, and discharge notes with your camera and keep them in the app. Scanning uses the document scanner built into your device (Apple VisionKit on iPhone, Google ML Kit Document Scanner on Android). You can capture up to 10 pages in one scan. Each scan is saved as a PDF in the app's private storage on the device.

For each document we store on the device:

• The PDF file (page images from the scan)
• A name you choose
• Optional tags you add (for example lab, prescription, 2026)
• Folder placement, including nested folders and folder names you create
• On-device recognised text from the pages (used for local search)
• Created / updated timestamps used for sorting and share file names

Free accounts keep up to 5 documents and can search by name and tag. Blood Snap Pro allows unlimited documents and can also search inside the recognised text of each document. Search and text recognition run on the device.

Scanned documents, their PDFs, folder structure, tags, and recognised text stay on your device. They are not uploaded to Blood Snap or Firebase, not sent to Groq, and not part of cloud sync between phones. A document leaves the app only when you tap Share PDF, which uses the system share sheet (for example Files, Drive, email, or Messages). The shared file is named with your document title plus the date and time so shares do not silently overwrite each other.

Blood Snap excludes the Document Vault folder from Android Auto Backup / device-to-device transfer and from iPhone and iPad device backups and iCloud, so scans are not included in your Google or iCloud phone backup. If the iOS backup-exclusion step fails, the scan is not saved. If you uninstall the app or change phones, scanned documents are not restored. Share a PDF to Files or Google Drive yourself if you want your own backup copy.

Voice entry

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

Logging tips translation

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

Your permission before any Groq sharing

Before personal data is sent to Groq, Inc., the app shows a dialog that does all of the following:

• Names the recipient: Groq, Inc.
• Lists the exact data for that feature (transcript, monitor text or cropped image, medicine label photo and text, or Logging tips text)
• Explains why it is sent
• Asks you to tap Allow or Not now

The privacy policy is not the permission step. Permission is collected in the app, separately for Snap & voice parsing, Medicine label scan, and Logging tips translation. You can turn each one off later in Settings → Privacy & AI. Choosing Not now does not block manual logging.

Groq, Inc. processes that data as our AI provider to return the parse or translation for that request. Under Groq's services terms, API inputs and outputs are not used to train models unless the customer explicitly allows it. Groq does not retain ordinary inference inputs by default, except temporary logs for reliability or abuse investigation for up to 30 days. Their privacy policy is at groq.com/privacy-policy, and their data handling note is at console.groq.com/docs/your-data.

Apple Health and Google Health Connect

Blood Snap can work with Apple's Health app (HealthKit) on iPhone and Google's Health Connect on Android. Access is off until you opt in and grant the operating-system permission sheet. We request only the types needed for the feature you turned on. Health data from these platforms is never used for advertising, never sold, and never sent to Groq as part of Health sync or metric display.

Two-way health sync (Blood Snap Pro) is off until you turn on Settings → Health & data → Sync with Health Apps and grant permission. You can enable these types separately:

• Blood pressure (and related pulse / heart rate from the cuff reading)
• Blood glucose
• Body mass / weight
• Sleep analysis (including writing manual sleep you logged in Blood Snap)

When a type is on, Blood Snap can read matching records from Apple Health or Health Connect into your diary and write readings you log in Blood Snap back to that health app. Turning sync off stops future sharing. Records already stored in Apple Health or Health Connect remain there until you delete them in that app.

Steps, sleep duration, and resting heart rate (free display metrics) are separate from Pro two-way sync. You switch each one on in the More Health tab. Blood Snap then asks for read permission and can show:

• Daily step count
• Sleep duration for the night
• Resting heart rate (daily average on Home / history; also charted in Insights under blood pressure when available)

Those Health reads are used for on-screen display when you open dashboard, history, or insights. They are not copied into Blood Snap cloud storage and are not sent to Groq. You can also log steps and sleep by hand in More Health; manual entries stay on the device. When both a Health reading and a manual steps total exist for the same day, the Health value is shown on Home. If Pro sleep sync is on, a manual sleep entry may also be written to Apple Health or Health Connect.

Import Apple Health Export is separate. You pick a ZIP or XML export file, and Blood Snap reads it on your device to import historical blood pressure, glucose, and weight. That file is not uploaded to Groq or to our servers as part of the import.

You can revoke Health access any time in iOS Settings → Privacy & Security → Health → Blood Snap, or in Android Health Connect / app permissions, and by turning sync or metric switches off in Blood Snap.

No advertising

Blood Snap does not show ads and does not include an advertising SDK. We do not collect advertising identifiers or share your data with ad networks. The app is supported by optional Blood Snap Pro subscriptions; the free tier remains available without a subscription.

Blood Snap Pro subscriptions

If you subscribe to Blood Snap Pro, payment and subscription status are processed by Apple or Google Play so we can unlock Pro features. We do not receive your full payment card details. Purchase history may be associated with your store account.

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, medicine tracking, and dose logs
• To power More Health tools: weight and BMI display (with cited public sources), water intake and daily goal, sleep log, steps log, and Home cards you enable
• To sync blood pressure, blood sugar, weight, and medicines across your devices when you are signed in with Pro cloud sync

We do not sell your health readings, More Health logs, medicine details, or scanned documents. We do not use Apple Health or Health Connect data for advertising or marketing.

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, and optional More Health values you enter or allow from Apple Health / Health Connect. It is not those devices and does not take a clinical measurement itself.

Third-party services

• Firebase (Google) — authentication and cloud database for signed-in Pro users (blood pressure, blood sugar, weight, medicines). Water, manual steps, Document Vault files/folders, and on-device-only sleep logs are not stored in Firestore.
• Groq, Inc. — optional snap/voice parsing, medicine label scan, and Logging tips translation. Data is sent only after you tap Allow in the app. Groq's privacy policy: groq.com/privacy-policy
• Apple Health (HealthKit) — optional Pro read/write of blood pressure, heart rate, glucose, weight, and sleep on iPhone, plus optional free read of steps, sleep, and resting heart rate, only after you grant Health permission
• Google Health Connect — optional Pro read/write of the same sync types on Android, plus optional free read of steps, sleep, and resting heart rate, only after you grant Health Connect permission
• Apple App Store / Google Play — subscription billing for Blood Snap Pro
• Google ML Kit — on-device text recognition for monitor snap and medicine labels. ML Kit does not send the image to Groq; a separate Allow step is required before any image or OCR text goes to Groq
• Apple VisionKit (iPhone) and Google ML Kit document scanner (Android) — on-device capture of Document Vault pages. Scanned PDFs, folders, tags, and recognised text are not sent to Blood Snap or Groq
• Resend — transactional website emails
• Google Tag Manager / Analytics — website analytics only

Data types at a glance

This table matches how we describe data in store “Data safety” / App Privacy labels. It is not keyword marketing.

Data retention and deletion

On-device data (including water, manual sleep, manual steps, Document Vault PDFs, folders, and tags) remains until you delete those items in the app, uninstall, or clear app storage. Cloud diary data (BP, sugar, weight, medicines) is removed when you delete your account in the app or request deletion by email. Waitlist emails are removed when you unsubscribe. Medicine label photos and voice audio are not kept in Blood Snap cloud storage. Copies written to Apple Health or Google Health Connect are controlled by those apps. Scanned documents are deleted from the device when you delete them in More Health → Documents or uninstall Blood Snap.

Children

Blood Snap is not directed at children under 13. We do not knowingly collect data from children.

Changes to this policy

We may update this policy. Material changes may be communicated via the app or email. Continued use after changes constitutes acceptance.

Delete your data

See Delete account & data for step-by-step instructions to remove your account and cloud readings.
