Security

Your privacy is our priority. Blood Buddy is built with security, anonymity, and control in mind, giving you powerful health insights while ensuring your data remains protected.

How We Protect Your Data

No Personal Information Collected

Blood Buddy does not collect or store any personally identifiable information (PII). Your name, email, and contact details are never required.

Instead, we use a Universally Unique Identifier (UUID) generated locally on your device to provide access without traditional logins.

✔ No accounts. No email required.

✔ Your data stays anonymous and under your control.

Local Processing & De-Identification

Your Data Stays Secure

Most data processing happens locally on your device, including extracting key markers from your blood test. This keeps sensitive data off external servers and under your control.

De-Identified Data Only

Any data sent to our servers is fully de-identified, meaning it cannot be traced back to you. We achieve this through:

✔ Pseudonymization – No names, dates of birth, or identifiable details are stored.

✔ Generalization – Sensitive values (e.g., cholesterol levels) are grouped into broader categories.

✔ Data Minimization – Only necessary data is used, and AI interactions are not stored.

Temporary PIN for Secure Syncing

To link multiple devices, a temporary PIN is generated. This PIN:

✔ Is short-lived and expires after use.

✔ Does not store personal data and is only used for device syncing.

✔ Is required to access data across devices - once lost, previously synced data cannot be restored.

Data Security & Encryption

Secure & Encrypted Storage

We use secure encryption to protect your de-identified data both in transit and at rest.

✔ All data transfers are encrypted using industry-standard protocols.

✔ Servers run on SOC 2 compliant infrastructure, ensuring security and reliability.

✔ Access to our systems is restricted to authorized personnel only.

AI Security & Local Processing

Any AI-driven insights remain local on your device and are not stored on our servers. AI interactions are anonymized and not linked to any user.

No Data Selling. No Advertisers.

Blood Buddy does not sell, share, or monetize user data. Your health information is never used for third-party advertising or marketing.

Your Control Over Your Data

You Can Delete Your Data Anytime

✔ You control your information - data can be erased from the app at any time.

✔ If you disconnect all synced devices, your data is gone forever (we do not keep backups).

You Are Responsible for Device Security

Because Blood Buddy does not require accounts, access is linked to your device(s). You are responsible for keeping your device secure.

✔ Lost your device? If you haven’t synced it using a PIN, previously stored data cannot be recovered.

Blood Buddy is Not a Medical Provider

Our insights are for educational purposes only.

Blood Buddy does not provide medical advice, diagnoses, or treatment recommendations. Always consult a healthcare professional for medical decisions.

Built for Trust & Transparency
