Cookie Policy
Last updated: October 2026
This policy explains the cookies and similar technologies used when you visit gemstrace.com. Strictly necessary cookies are required for the site to work; analytics and marketing cookies are activated only with your explicit consent. Without consent these cookies are not set and Google Tag Manager is not loaded.
What are cookies?
Cookies are small text files a website stores in your browser. We use them to keep you signed in, to keep the site secure and — only if you agree — to measure anonymously how the site is used.
Categories
Necessary: session, security (CSRF, two-factor authentication) and storing your cookie choice — always on. Analytics: anonymous visit statistics with Google Analytics 4 — consent only. Marketing: not currently used; if introduced it will require consent.
Google Consent Mode v2
We use Google Consent Mode v2. Every optional purpose defaults to 'denied'. No analytics tag runs and no data is sent before you consent.
International transfers
If you consent to analytics cookies, measurement data may be processed by Google LLC on servers outside Türkiye. This transfer relies on your explicit consent, which you can withdraw at any time.
Your rights
To exercise your rights under KVKK and GDPR (access, erasure, objection, etc.), use the contact details in our Privacy notice.
