Privacy Policy

Last updated: April 24, 2026

1. Data Controller

The data controller for your personal data is:
Michał Bazyli Blockchain Security
ul. Topazowa 7
45-940 Opole, Poland
NIP: 7543044815
Email: contact@blubio.app

2. Data We Collect

We collect only the data necessary to provide the Blubio service:

  • Account data — email address and authentication information provided when you sign up.
  • Profile data — optional information such as age, sex, and wellness-related profile details, used to personalize responses.
  • Health and wellness content — health-related information you choose to share, including biomarkers, lab results, symptoms, supplements, training, sleep, and other wellness context provided in your profile or chats.
  • Chat messages and prompts — the questions you send and the responses you receive, stored to maintain your conversation history.
  • Purchase data — subscription status, billing period, and transaction state needed to provide paid features. We do not store payment card numbers or bank account details on our servers.

3. How We Use Your Data

  • To operate and deliver the AI biohacking assistant service.
  • To personalize responses based on your profile and the health or wellness information you choose to provide.
  • To manage your subscription and provide paid features through the App Store on iOS and Stripe on the web.
  • To send transactional emails (account confirmation, billing receipts).
  • To diagnose technical issues and keep the service operating reliably.

We do not sell your data to third parties. We do not use your chat messages to train AI models without your explicit consent.

4. Third-Party AI Processing

When you send a chat message after giving in-app permission, Blubio sends the data needed to provide the AI response to third-party AI providers. This includes your chat text, recent conversation context, and retrieved wellness context used to answer your question. It may include personal or health details only if you choose to type them in chat. We do not send your email address, billing information, account identifiers, or profile age/sex fields to third-party AI providers. We use xAI to generate AI responses and OpenAI, L.L.C. to create embeddings from your message to search relevant knowledge.

We share this data only to operate the AI assistant and retrieve relevant context. These providers are required to protect the data with safeguards appropriate for this processing. You can choose not to agree to AI data sharing; in that case, chat messages will not be sent for AI processing.

5. Payment Processing

On iOS, in-app subscriptions are processed by Apple through the App Store. On the web, payments are processed by Stripe, Inc., a third-party payment processor. When you subscribe on the web, you are subject to Stripe's Privacy Policy. We receive only subscription status, billing period, and transaction state information — never your full card details.

6. Data Retention

We retain your account and chat data for as long as your account is active. If you delete your account, we will delete your personal data within 30 days, except where retention is required by law.

7. Your Rights (GDPR)

As a resident of the European Union, you have the right to:

  • Access the personal data we hold about you.
  • Correct inaccurate data.
  • Request deletion of your data ("right to be forgotten").
  • Object to or restrict processing of your data.
  • Receive your data in a portable format.
  • Lodge a complaint with your national data protection authority.

To exercise any of these rights, contact us at contact@blubio.app.

8. Cookies

Blubio uses only functional cookies necessary for authentication and session management. We do not use advertising or tracking cookies.
