Sigma Smile Clinic ("we", "us") respects your privacy. This policy explains what personal data we collect through this website and our online consultation service, why we collect it, and the rights you have. We process personal data in line with the Egyptian Personal Data Protection Law No. 151 of 2020 and generally accepted medical confidentiality standards.
1. Who is responsible for your data
The data controller is Sigma Smile Clinic, Nasr City, Cairo, Egypt. You can contact us about privacy at info@sigmasmile-eg.com or on WhatsApp at +20 111 677 5077.
2. Data we collect
- Booking details: full name, age, phone number, email address, chosen treatment, doctor, date, time and visit type, and any notes you write.
- Health information: information you share about your dental condition in the booking form, during a consultation, or that the doctor records as consultation notes. This is sensitive data and is handled with extra care.
- Payment information: amount, method, status and transaction reference. Card and wallet details are entered on Paymob's secure pages; we never see or store your full card number. For InstaPay we keep the reference and the transfer screenshot you upload.
- Video consultations: audio and video are transmitted directly between your browser and the doctor's browser (peer-to-peer, encrypted with DTLS-SRTP). We do not store calls on our servers. A doctor may record a session only after informing you in the call; recordings are stored on the clinic's computer and treated as part of your medical record.
- Technical data: IP address, browser type, language preference, and essential cookies required to run the site. Analytics cookies are only used if you accept them.
3. Why we use your data (purpose and legal basis)
- To schedule, confirm, remind you about and manage appointments (performance of the service you requested).
- To provide dental care and online consultations and keep medical records (healthcare provision and legal obligations).
- To process payments and prevent fraud (contract and legitimate interest).
- To send service emails such as confirmations, reminders and video links (service necessity). We only send marketing messages if you explicitly agree.
- To improve the website using anonymous statistics (your consent, via the cookie banner).
4. Who we share data with
We never sell your personal data. We share it only with service providers that help us run the service, under confidentiality obligations:
- Paymob (payment processing), banks and InstaPay for transfers;
- Our hosting and email provider (Hostinger) to store the website database and send emails;
- Video connection relay servers (STUN/TURN) that help browsers connect; they relay encrypted media and cannot view it;
- Authorities when the law requires it.
5. How long we keep data
Appointment and medical records are kept for as long as needed for your care and as required by Egyptian medical regulations. Payment records are kept as required by tax law. You can ask us to delete booking data that we are not legally required to keep.
6. Security
The site is served over HTTPS, the dashboard is protected by individual staff accounts with hashed passwords, access is limited to authorised staff, and video calls are end-to-end encrypted by your browser. No system is 100% secure; if a breach affecting you occurs we will notify you and the competent authority as required by law.
7. Your rights
You may request access to your data, correction, deletion, restriction or objection to processing, withdraw consent at any time, and receive a copy of your data. Contact us at info@sigmasmile-eg.com. You may also complain to the Egyptian Personal Data Protection Center.
8. Children
Bookings for patients under 18 must be made by a parent or legal guardian, who consents on the child's behalf.
9. Changes
We may update this policy. The date at the top shows the latest version; important changes will be announced on the website.
