Privacy and Personal Data Protection Notice

Last updated: 15 October 2026

This notice explains, under Turkey’s Law No. 6698 on the Protection of Personal Data (“KVKK”), for what purposes and how the personal data of excelozeldersi.com visitors and of students attending the Excel lessons is processed. It is a translation of the Turkish notice; in case of any discrepancy, the Turkish version prevails.

1. Data controller

Your personal data is processed by Doğukan Özdağ as the data controller. Contact: iletisim@excelozeldersi.com

2. Personal data processed

  • Identity and contact details: First and last name, phone number and email address.
  • Lesson details: The content of your messages, your Excel level and goals, lesson days and times.
  • Lesson recordings: Video and audio recordings of online lessons, including screen sharing.
  • Payment details: The sender’s name and bank details shown on a bank transfer.
  • Site usage data: Technical logs kept by the hosting provider Cloudflare when you visit the site, such as IP address, browser information and time of visit.

Lessons are recorded so that students can watch them again later. If you do not want a lesson to be recorded, simply say so before the lesson.

3. Purposes of processing

Your personal data is processed in order to:

  • Answer your lesson requests and questions, and plan the free first lesson and the lesson schedule,
  • Run the online lessons and share the lesson recordings and files with you,
  • Keep track of payments and meet legal obligations,
  • Keep the site secure and measure visits in aggregate.

4. Legal grounds

Your personal data is processed on the following legal grounds set out in Article 5 of the KVKK:

  • It is necessary for concluding and performing the contract for the lessons (communication, lesson planning, running the lessons, sharing the recordings and keeping track of payments),
  • It is necessary for the data controller to comply with a legal obligation (keeping payment records),
  • The legitimate interests of the data controller, provided that your fundamental rights and freedoms are not harmed (site security and aggregate visit statistics).

5. Transfer of personal data

Your personal data is shared only with the following service providers, used for the purposes above:

  • Cloudflare: Hosting and security of the site, email forwarding and visit statistics.
  • Google: Email (Gmail), online lessons (Google Meet), storing and sharing lesson recordings and files (Google Drive).
  • Microsoft: Online lessons (Microsoft Teams).
  • WhatsApp: Messaging.

As the servers of these providers may be located outside Turkey, your personal data may be transferred abroad when these services are used. Apart from this, your personal data is shared only with public authorities legally entitled to request it, within legal limits. Your personal data is never sold to third parties.

6. How the data is collected

Your personal data is collected electronically and directly from you via WhatsApp, email and the online lesson programs (Microsoft Teams, Google Meet). Site usage data is recorded automatically by the Cloudflare infrastructure when you visit the site.

7. Cookies

This site does not use cookies. Visits are measured in aggregate with Cloudflare Web Analytics, which does not use cookies and does not identify visitors personally.

8. Retention

Lesson recordings and student details are deleted within 6 months at the latest after the training is completed. Payment records are kept for the period required by the applicable legislation. On request, data that is not subject to a legal retention obligation is deleted without waiting for this period.

  • Learn whether your personal data is processed,
  • Request information about it if it has been processed,
  • Learn the purpose of the processing and whether the data is used in line with that purpose,
  • Know the third parties in Turkey or abroad to whom it has been transferred,
