Privacy Notice

This notice explains which personal data we process when you browse the site, write to us or work with us. It also explains why we process it, who we transfer it to, how long we keep it and what your rights are.

Version 1.1 · Effective 14 October 2026 · Last updated 15 October 2026

This is an English translation for convenience. The Turkish version is the legally binding text: Türkçe metin.

In short

The site has no user accounts and no tracking cookies. When you browse the site, only our server keeps a technical log for security (IP address, date, page opened).

If you write to us or ask for a meeting, we use your details to reply to you and to arrange the meeting. If you work with us, we use them to perform the contract and to invoice.

We do not sell your data and we do not share it with anyone for advertising. We send you newsletters or promotional messages only if you give us permission. You can withdraw that permission at any time.

This notice only informs you. It does not ask for your consent.

2. Scope of this notice

This notice was prepared under Article 10 of KVKK and the Communiqué on the Procedures and Principles to Be Followed in Fulfilling the Obligation to Inform. It covers:

  • The Solon website and all of its subpages.
  • The data we process when you reach us through the meeting form on the site, email, phone, a LinkedIn message or a video call.
  • The data of the officers and employees of our customers, suppliers and business partners who do business with us.
  • The data of people who give us consent to send commercial electronic messages.

Cookies are explained in a separate text, the Cookie Policy.

Data processed inside the Solon product is outside the scope of this notice. When our customers deploy Solon in their own companies, the customer is the data controller for the data of the employees Solon talks to and for the data in the systems Solon connects to. We are a data processor acting on the customer's behalf and on its instructions. This data is governed by the contract between us and our customer. To exercise your rights over this data, apply first to the company you work for. If your request reaches us, we forward it to them.

If we carry out any processing based on explicit consent, we ask for your consent separately from this notice. This follows the Personal Data Protection Board (the Board) principle decision No. 2026/347 dated 18.02.2026. Reading this notice does not mean that you consent to anything.
