Scope: This notice covers the data-processing activities of the HekimDoktor patient mobile app(iOS / Android) under the General Data Protection Regulation (EU) 2016/679 (“GDPR”). Our B2B web platform for doctors and clinics (klinik.bio) has a separate privacy notice.

2. Categories of Personal Data

2.1 General Personal Data (GDPR Art. 4(1))

  • Identity: name, date of birth, gender
  • Contact: email, phone, address
  • Transaction: subscription, payment history, appointments
  • Security: IP address, device/browser info, login timestamps
  • Marketing (optional): newsletter preferences

2.2 Special Categories of Personal Data (GDPR Art. 9)

As a health platform we process the following special-category data on the basis of your explicit consent (GDPR Art. 9(2)(a)):

  • Health data: symptoms, diagnoses, medications, lab results, vitals (blood pressure, glucose, etc.)
  • Menstrual cycle, pregnancy, women's health
  • Mental health, nutrition, exercise, sleep tracking
  • Smoking cessation, addiction tracking
  • Biometric data read from Apple HealthKit / Google Health Connect on your device with your permission (steps, heart rate, sleep, blood pressure, etc.) — read locally, processed only for features you select.

3. Legal Bases and Purposes (GDPR Art. 6 & Art. 9)

  • Contract performance (Art. 6(1)(b)): account creation, authentication, appointments, messaging, prescriptions, doctor-patient records
  • Explicit consent (Art. 6(1)(a) / Art. 9(2)(a)): AI-powered health assistant, symptom triage, nutrition recommendations, cross-border data transfers. Via Profile → AI Data Sharing you can approve or revoke each AI provider individually at any time.
  • Legitimate interest (Art. 6(1)(f)): service quality and error monitoring via anonymous telemetry (Sentry). No identifiable personal or health data is included. Our interest is balanced against your rights.
  • Legal obligation (Art. 6(1)(c)): compliance with applicable law and lawful requests from competent authorities.
  • Marketing communication (only with opt-in consent — you may withdraw at any time).

Voice input uses Apple Speech Framework on iOS and Google Speech Services on Android for on-device transcription. Audio is not uploaded — only the resulting text is sent to Anthropic with your consent.

3.1 Nature of AI Content

AI health assistants provide general information only — they are not a substitute for medical diagnosis, treatment, or professional healthcare. In a medical emergency call the emergency number in your country (112 in the EU, 999 in the UK).

Sources used in AI output are listed inside the app under "Medical Information Sources" and include WHO standards, CDC recommendations, EU CosIng databases, and USDA FoodData Central.
