Cookie and Advertising Policy

Version 1.0.0 · Effective October 3, 2026

This policy explains how Dijital Dergicilik Okulu ("DDO") uses cookies, local storage and similar technologies on www.dergicilikokulu.com, and how you can manage your advertising choices. Please read it together with our Privacy Policy.

1. What Are Cookies and Local Storage?

Cookies are small text files saved on your device when you visit a site. Local storage (localStorage, sessionStorage) is a similar technology that keeps data in your browser. They can be used to make the site work, remember your preferences, measure usage and show ads.

2. Types We Use

2.1 Strictly necessary (no consent required)

These are essential for the site to work and cannot be switched off.

• Session and authentication: Firebase Authentication session data, which lets you sign in and keeps your session secure.
• Language preference: remembers your chosen interface language.
• Theme preference: remembers your light or dark display choice.
• Progress cache: data temporarily stored in your browser so your lesson progress loads quickly.
• Cookie choice: your cookie consent or refusal.

2.2 Analytics

• Google Analytics: measures aggregated statistics such as pages visited, visit duration, device and general location to help us improve the site. In regions where consent is required, it is not activated without your consent.

2.3 Advertising

• Google AdSense: used to show ads on content pages.
• Google Ads / remarketing tag: may be used to measure ad performance and to show ads to people who have previously visited the site.
• YouTube embeds: when a page loads or you play a video, YouTube/Google may set its own cookies.

These are third-party cookies (mainly Google's). DDO does not control their content.

3. Google Advertising Disclosure

• Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this site or other sites.
• Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet.
• Personalised ads are based on your behaviour and interests; non-personalised ads are based only on contextual data such as the content of the page and general location.
• You can opt out of personalised advertising at Google Ads Settings.
• For information on how third-party vendors use cookies, see How Google uses data when you use our partners' sites and Google advertising technologies.
• You can also opt out of personalised ads from many other vendors at www.aboutads.info and www.youronlinechoices.eu.

For visitors in the EEA, the United Kingdom and Switzerland, consent for personalised ads and analytics cookies is collected through a Google-certified consent management platform (CMP). You can use the site without giving consent; in that case only strictly necessary cookies and, where applicable, non-personalised ads are used.

4. About Advertisements

Ads may appear on content pages. Ad content belongs to advertisers and third-party providers; DDO does not endorse, recommend or guarantee the ads or the products and services advertised. Ads do not affect how educational content, exam results or certificates are assessed.

5. How to Change Your Choices

• On the site: use the "Cookie Settings" link in the footer to change or withdraw your consent at any time.
• In your browser: you can block or delete cookies in your browser settings. If you block strictly necessary cookies, functions such as signing in may not work.
• Google and industry tools: adssettings.google.com, aboutads.info, youronlinechoices.eu.

6. Retention

Session cookies are deleted when you close your browser or the session expires. Preference cookies are generally kept for up to one year, and analytics and advertising cookies for the periods set by the provider (usually from a few months up to two years). You can delete local storage data from your browser at any time.

7. Changes

We may update this policy; the current version number and effective date are shown above. For material changes we may ask for your consent or acceptance again.
