Privacy Policy

The person responsible for this website is Zakir Mustafa Kemal Kalayci. For privacy questions or requests, contact mkemalkalayci@gmail.com.

This policy applies to the public portfolio pages and the Testing Lab, including the AI Portal demo. The website uses cookieless, aggregated analytics to count page views, described in section 5. It does not use advertising trackers, tracking pixels, cross-site tracking, or automated profiling.

Most interactive demo information stays in your browser. Technical request data may still be processed by the hosting infrastructure when it sends the website to your device.

When you access a page, the hosting infrastructure may process technical information such as your IP address, request date and time, requested URL, browser or user agent information, referring page when supplied, response status, and transferred data volume. This information is used to deliver the site, maintain reliability, and protect the service against abuse.

Where the GDPR applies, the legal basis for this processing is the legitimate interest in securely and reliably providing the website (Article 6(1)(f) GDPR). Technical records are handled according to the hosting and security configuration in use when the website is accessed. If the hosting provider changes, this policy will be updated where that change materially affects how personal data is processed.

The site uses local storage for the selected theme and for functionality you choose to use inside the Testing Lab. The AI Portal demo can store demo users and sessions, profile changes and optional profile images, simulated purchases and limited payment metadata, comments, reactions, favorites, experiment preferences, and Article Studio drafts or published articles, including an optional uploaded image.

The application code keeps this demo information on your device and does not send it to an application database. It remains until you use the relevant reset controls, delete it in the demo, or clear this website's browser data. Local storage is used to provide preferences and demo features you explicitly request. In Germany, access that is strictly necessary to provide a requested digital service is addressed by Section 25(2)(2) TDDDG.

The website code does not set cookies and does not use behavioral advertising or cross-site tracking.

Page views are measured with Vercel Web Analytics, provided by the hosting provider. It does not use cookies and does not store or read identifiers on your device. Visitors are counted using a hash derived from the incoming request, which is discarded after 24 hours, so visits cannot be linked together beyond that window or across other websites.

A page view may record the time of the request, the page address and route, the referring website, filtered query parameters, approximate location (country, region, city), device type, operating system, and browser version. This information is used in aggregate and is not used to identify individual visitors.

The legal basis is Art. 6(1)(f) GDPR: the legitimate interest in understanding which pages are used, measured in a form that does not identify visitors. Because no information is stored on or read from your device, the site does not display a consent banner. If non-essential tracking technologies are introduced later, this policy and the consent approach will be updated before they are used where required.

If you contact Zakir Mustafa Kemal Kalayci by email, the information you send—such as your email address, name, message, and attachments—is used to respond to and manage the request. Depending on the request, the legal basis is Article 6(1)(b) GDPR for steps connected with a possible contract or Article 6(1)(f) GDPR for the legitimate interest in handling general correspondence.

The site links to third-party services such as GitHub, LinkedIn, Gmail, or Google. When you follow an external link, that provider may receive technical request data and applies its own privacy policy. This website does not control the third party's subsequent processing.

• Browser-local demo data remains until you delete or reset it, or clear the website's browser storage.
• Email correspondence is retained only as long as reasonably needed to handle the request and meet any applicable legal obligations.
• Technical hosting records are retained according to the hosting and security configuration and only for as long as needed for delivery, reliability, security, or applicable legal requirements.

Where the GDPR applies, you may have rights to access, correct, erase, restrict, or receive personal data, and to object to certain processing. You may withdraw consent at any time where processing relies on consent, without affecting earlier lawful processing. You may also lodge a complaint with a competent data protection supervisory authority.

You can remove browser-local demo data directly with the Testing Lab's reset controls or your browser settings. For information not controlled by this site, such as hosting-provider records, requests may need to be directed to the relevant provider. More information is available from the European Commission's data protection guidance.

This website does not make legally significant automated decisions about you. Paywall variants, subscription states, and payment results inside the AI Portal are fictional demo behavior only.

This policy may be updated when the site, its hosting, or applicable requirements change. The date at the top identifies the current version. Material changes will be reflected on this page.

Rules for using the website and its demos are available in the Terms of Use.
