Cookie Policy.
This page describes the cookies and similar technologies used on opsidatech.com and opsida.com.tr, their purpose and retention, and how you can manage them. It is aligned with KVKK Art. 5/1, GDPR Art. 7 and ePrivacy Directive Art. 5(3).
What is a cookie
A cookie is a small text file that a website stores in your browser. Cookies may keep you signed in, remember preferences such as language or theme, or anonymously measure how a site is used. This site also uses your browser's local storage solely to remember your cookie choice.
Categories and consent model
Cookies are grouped into three independent categories, each with its own opt-in. Strictly necessary cookies operate at all times under the legal basis of contract performance (KVKK Art. 5/2(c)). Analytics and marketing cookies require your explicit consent (KVKK Art. 5/1; GDPR Art. 7) and are not loaded until you accept them. Until you choose, no optional cookie runs.
- Strictly necessary — always on. Session, security (CSRF), language and theme preference, the consent record itself.
- Analytics — opt-in. Anonymous pageview counts via Vercel Web Analytics. Uses no cookies and no on-device storage; if you decline, the script is never loaded, and if you withdraw consent, measurement stops immediately.
- Marketing — opt-in. Newsletter click measurement and limited remarketing pixels. May not be active at this time.
Cookies in use
| Name | Category | Provider | Purpose | Retention |
|---|---|---|---|---|
| opsida.consent.v2 | Strictly necessary | Opsida (1st party, localStorage) | Stores your cookie preference. Without it, the bar appears on every visit. | 12 months |
| NEXT_LOCALE | Strictly necessary | Opsida (1st party) | Remembers your selected language (tr/en). | 12 months |
| sb-access-token / sb-refresh-token | Strictly necessary | Supabase (only on /admin) | Keeps an authorised user signed in. Not loaded for public visitors. | Session |
| — (no cookie used) | Analytics | Vercel, Inc. (USA) — Vercel Web Analytics | Anonymous pageview counts. Creates no cookie or localStorage entry in your browser; loaded only if you grant analytics consent. | No storage on your device |
The list may change. When a new cookie category is added, the consent policy version is incremented and current preferences are re-requested.
Managing your preferences
Use the “Cookie preferences” link in the site footer at any time to reopen the consent dialog and grant or withdraw consent per category. Withdrawing consent is as easy as giving it (KVKK Art. 5/1; GDPR Art. 7(3)). You can also clear or block cookies in your browser settings:
- Chrome: Settings → Privacy and security → Cookies and other site data
- Safari: Preferences → Privacy → Manage website data
- Firefox: Settings → Privacy & Security → Cookies and Site Data
- Edge: Settings → Cookies and site permissions → Manage cookies and site data
Blocking strictly necessary cookies in your browser may break core functionality (e.g. language selection or admin sign-in).
Third parties and international transfer
We do not use third-party advertising networks, social media embeds, or session replay tools, and measurement data is not shared with advertising platforms. Our hosting and database infrastructure is located within the European Union (Frankfurt). If you grant analytics consent, pageview data is processed by Vercel, Inc. (USA), the provider of that service; this is a transfer outside Türkiye and falls under KVKK Art. 9. If you decline analytics, the measurement script is never loaded and no such transfer takes place.
