Phone: 087 856 0490

2. What Data We Collect and Why
2.1 Appointment Booking
When booking an appointment, we collect: first and last name, phone number, email address (optional), and any notes about the reason for the visit. This data is necessary for the performance of the treatment contract (Art. 6(1)(b) GDPR).
2.2 Patient Record
During treatment, we process health data (dental chart, treatment history). This is processed to comply with legal obligations in the healthcare sector (Art. 9(2)(h) GDPR).
2.3 Reminder Emails
With your explicit consent, we send appointment reminders and preventive care prompts by email (Art. 6(1)(a) GDPR). This consent can be withdrawn at any time.
2.4 Contact Form
Messages sent through the contact form are stored to respond to your enquiry (Art. 6(1)(b) GDPR).
3. Retention Period
Patient records are retained for 10 years in accordance with Bulgarian regulations for dental records (Наредба № 3). After this period, records are deleted. Email consent records are retained until withdrawn.
4. Sharing of Data
Your data is never sold to third parties. To send confirmation and reminder emails, we use an SMTP service provider. This provider processes only the email address and message content, and is bound by a data processing agreement.
5. Your Rights
You have the right to:
- Access the data held about you (Art. 15 GDPR)
- Rectification of inaccurate data (Art. 16 GDPR)
- Erasure, where no legal retention obligation applies (Art. 17 GDPR)
- Restriction of processing (Art. 18 GDPR)

- Objection to processing (Art. 21 GDPR)
- Withdrawal of any consent given, at any time
To exercise your rights, contact us by email or phone. You also have the right to lodge a complaint with the supervisory authority — in Bulgaria this is the Commission for Personal Data Protection (CPDP), www.cpdp.bg.
6. Cookies
We use only a technically necessary session cookie (kd_session)

close your browser. No tracking or analytics cookies are used.
