Privacy notice
Last updated: 15 November 2026
Who is responsible
Data controller: [doldurulacak]. Contact for privacy questions: [email protected].
What we collect
Only your e-mail address, and only if you join the waitlist. The site itself has no accounts and no other forms. We do not collect health information.
Why, and on what basis
To send you a launch notification for the Contrast app and a short newsletter with new lessons. The legal basis is your consent (GDPR Art. 6(1)(a); KVKK Art. 5 explicit consent). Sign-up uses double opt-in: you are only added after you confirm from your inbox.
Who processes it
The waitlist and newsletter run on Beehiiv, which stores your address and sends the e-mails on our behalf. Beehiiv may process data outside Türkiye and the European Economic Area; its own privacy policy applies to its processing. The form is loaded from Beehiiv only on the page section that shows it.
How long we keep it
Until you unsubscribe or ask us to delete it. Every e-mail has an unsubscribe link.
Your rights
You can ask to see, correct, delete or export your data, withdraw consent at any time, and object to processing (GDPR Art. 15-21; KVKK Art. 11). Write to [email protected]. You can also complain to your data protection authority (in Türkiye: Kişisel Verileri Koruma Kurumu).
Analytics and cookies
We use Cloudflare Web Analytics, which does not use cookies and does not build profiles of visitors. We set no cookies of our own and show no ads. The site is hosted on Cloudflare Pages.
Videos
Lesson videos are embedded from YouTube in privacy-enhanced mode (youtube-nocookie.com) and load only when you click play. Until then, nothing is requested from YouTube.
Changes
If this notice changes, the date above changes with it.
