Cookie Policy
This policy explains how cookies and similar technologies are used on the HEY Mimarlık website. For general information about how we process personal data, see the Privacy Notice.
What a cookie is
A cookie is a small text file saved to your browser when you visit a site. When you return, your browser sends it back and the site recognises you, which is how things like your language preference or session are kept. In this policy "cookie" also covers similar technologies that store data in your browser, such as localStorage.
Our approach
No non-essential cookie is written before you consent. On your first visit you are asked for a preference. If you choose "Essential only", the measurement tool writes no cookies and creates no identifier for you; it only makes an anonymous count of how often the page was opened. If you choose "Accept", measurement cookies are enabled and your visit can be analysed in detail. The preference itself is stored in your browser so you are not asked again on every page.
Cookies we use
1. Strictly necessary cookies
These are required for the site to work and are not subject to consent. Without them you cannot submit forms or sign in.
| Name | Purpose | Duration |
|---|---|---|
| Session cookie | Maintains continuity during form submissions and panel sessions. | For the session |
| CSRF token | Verifies that a form submission genuinely came from this site, blocking forged requests. | For the session |
hey-consent |
Stores your cookie preference so you are not asked on every page. Kept in your browser's localStorage and never sent to the server. | Until you clear it |
2. Measurement cookies (consent based)
These load only when you choose "Accept". They are used to understand which pages are read and how visitors move through the site, so the content can be improved.
| Name | Purpose | Duration |
|---|---|---|
Google Analytics (_ga, _ga_*) |
Measures page views and visit flow. The IP address is anonymised before transmission. | Set by the provider, up to 2 years |
The measurement tool runs only if a measurement ID has been configured in the admin panel. If none is set, no measurement cookie loads even after you accept.
3. Cookies we do not use
The site carries no advertising cookies, no retargeting pixels and no social media tracking code. We do not build visitor profiles and we do not sell this data to third parties.
Measurement without cookies
We record clicks on the phone and WhatsApp links to see which pages lead to contact. This record uses no cookies and does not identify you; it consists of the type of click, its time, the page it happened on, the IP address and the device and browser type. Records are deleted automatically after 180 days. Section 2 of the Privacy Notice covers this in detail.
We also count how often each page is read, on our own server. This count uses no cookies either: what we store is the page opened, its language, the domain you came from (for example google.com) and whether your device is mobile or desktop. Your IP address and browser details are not stored; instead we keep an irreversible signature generated with a key that changes every day. The signature only distinguishes repeat visits within the same day; because the key changes the next day, records cannot be linked across days. The data stays on our server, is not transferred abroad, and is deleted after 365 days. This count runs regardless of your cookie choice; its legal basis is the legitimate interest provision in Article 5/2-f.
Changing your preference
On the site: clearing site data in your browser resets your cookie preference and the question is asked again.
In your browser: you can block or delete cookies at any time. The relevant settings are found under:
- Chrome: Settings › Privacy and security › Third-party cookies
- Safari: Settings › Privacy
- Firefox: Settings › Privacy & Security
- Edge: Settings › Cookies and site permissions
Blocking strictly necessary cookies may stop functions such as form submission from working.
Legal basis
Strictly necessary cookies rely on the legitimate interest ground in Article 5/2-f of Law No. 6698. Measurement cookies rely solely on your explicit consent under Article 5/1; declining restricts no functionality.
Updates
This policy is updated whenever the cookies used on the site change, and the current version is always published on this page.
