We use this information to show the site to you and to protect it against attacks and excessive load. Legal basis: KVKK Article 5(2)(f).

3.3 Your Document Requests and E-mails

These e-mails, and other e-mails you send to the e-mail address on our site, reach DİPER's e-mail inbox directly; they do not pass through our site and are not stored on our site. We use your e-mail address and the information in your message to assess your request and to send you the documents. Legal basis: KVKK Article 5(2)(f).

Legal basis: KVKK Article 5(2)(ç).
3.5 Visit Statistics
If you give your consent, we use a visit statistics (analytics) service to measure how often our pages are visited and where visitors come from. You can give your explicit consent with the "Accept" button, or by turning on the "Analytics Cookies" option in the panel that the "Manage Cookies" button opens and clicking the "Save Preferences" button. Legal basis: KVKK Article 5(1). If you do not give your consent, the service is not started and no information is sent to any service provider for this purpose.
After your consent, the tag management and statistics codes loaded into your browser send the following information to their providers: the identifier that distinguishes your browser from those of other visitors and is recorded in cookies; the addresses of the pages you open and of the previous page you came from; your actions, such as reaching the end of a page or clicking a link that leads to another site or downloads a file; your browser, operating system and device information; your IP address. The statistics service provider determines your approximate location (country, region and city) from your IP address.
You can withdraw your consent at any time: click the "Cookie Preferences" text at the very bottom of our pages, then the "Reject" or "Necessary Only" button. The statistics cookies are deleted from your browser, and the service is not started unless you give your consent again. Withdrawing your consent does not delete the information already sent to the providers.
