This policy explains cookies, browser-stored preferences and external content on the website of Prof. Dr. Melih Güven’s practice.
1. Cookies and similar technologies
Cookies are small records that a website can store in your browser. This website also uses localStorage, which is not a cookie, to remember your privacy choices. Necessary session functions are separate from optional analytics and external-content choices.
2. Technologies used
The necessary session supports form security and continuity between pages. Analytics and external-content options are off initially. The marketing category is disabled in the current configuration.
| Item | Purpose / provider | Storage / loading |
|---|---|---|
| melihguven_session | Session and form security / this website | Session cookie; does not depend on optional permission. |
| mg_cookie_consent_v{N}_r2 (localStorage) | Privacy preferences / this website | Up to 180 days; N is the preference version in the administration panel. Not a cookie. |
| _ga, _ga_7PJGRVRS1L | GA4 analytics if allowed / Google | Up to 400 days in Chrome; service settings and other browsers may impose shorter durations. |
| Google Maps, YouTube and external covers | Maps, videos and covers / Google services | Depends on your loading choice; provider cookies vary by service and browser. |
3. Google Analytics 4
The Google Analytics 4 tag does not load and no measurement requests are sent to this service before you allow analytics. If you give permission, Google Analytics 4 loads and may use the first-party cookies _ga and _ga_7PJGRVRS1L to assess website usage. This integration does not grant advertising storage or ad-personalisation permissions. Refusing analytics does not prevent you from using appointment and contact forms.
4. Maps and video content
Google Maps and YouTube players do not load initially. You can select “Load this content once” in the relevant notice to open just that item, or allow these services through the “External content” preference. One-time loading does not save a general permission. YouTube uses the privacy-enhanced player domain; this does not mean that no data is sent to the provider or that no cookies are used. External video covers also depend on external-content permission; local covers load from this website.
5. Changing your preferences
Use “Cookie Preferences” at the bottom of the page to change analytics and external-content choices separately. “Only necessary” disables optional categories. When you withdraw analytics permission, this website’s analytics cookies are cleared. If analytics code has already loaded, the page reloads automatically; after the reload, the Google Analytics tag does not load and no new measurement requests are sent to this service. Your necessary session is preserved. Withdrawing external-content permission restores the loading notices for embedded content. Data transfers that have already begun cannot be undone.
6. Storage and browser settings
Your choice is shared across website languages in the same browser for up to 180 days. You are asked again when it expires or is invalid. If your browser does not allow storage, the choice applies to that page and you may be asked again. You can delete or restrict cookies and site data in your browser. Deleting session data may end signed-in sessions. Google’s default Analytics cookie duration is 2 years. However, Chrome limits a cookie’s lifetime to a maximum of 400 days from the time it is set or updated. In a check performed in Chrome on 20 October 2026, the remaining storage period of the _ga and _ga_7PJGRVRS1L cookies was approximately 400 days. Service settings and other browsers may impose shorter durations. Updating a cookie may reset its expiry date. Data stored by external providers on their own domains is managed under their rules and your browser settings.
