# Cookie Policy and Inventory

Version 2.0 · Effective: 21 September 2026

English information version. If there is any inconsistency, the Turkish version applies.

### Current use

WOLFR’s public website does not use cookies for advertising, behavioural marketing, visitor analytics or personalisation. Language is selected through the page address, and demo selections are retained only in the memory of the open page. No persistent visitor profile is created through localStorage or sessionStorage.

### Cookie inventory

| Cookie or tool | Provider and scope | Purpose | Duration | Category |
| --- | --- | --- | --- | --- |
| **__cf_bm** | Cloudflare; wolfr.com.tr | Distinguish automated or malicious traffic and protect the website | Approximately 30 minutes after the last activity | Strictly necessary security cookie |
| **wolfr_preview** | WOLFR; authorised owner preview only | Show the otherwise unpublished main website to the owner for one hour | Up to 1 hour | Strictly necessary administration cookie |
| Administrator authentication cookies | Sign-in with ChatGPT; authorised person accessing /yonetim only | Authenticate the website owner and prevent unauthorised access | According to the identity provider’s session policy | Strictly necessary administration and security cookie |

Cloudflare may process security-cookie data in global data centres, including in the United States, by default. The __cf_bm value is encrypted and generated separately for each website. It does not correspond to a user account in the WOLFR application.

### Why is there no cookie banner?

The current version uses only tools necessary to deliver the service securely and to administer the website. Because there is no analytics, advertising or personalisation tool requiring explicit consent, visitors are not shown an accept or reject banner. If such a tool is introduced, it will be disabled by default and equally prominent “Accept”, “Reject” and “Preferences” options will be presented before it operates.

### Browser settings and changes

You may delete or block cookies in your browser. Blocking a necessary security cookie may affect website availability or security checks. The inventory will be updated before a new tool is activated. Contact: **info@wolfr.com.tr**.
