2.What we don't use
- Analytics and advertising cookies: None. We do not use tools such as Google Analytics or Meta Pixel.
- Fonts: Served from our own server; no requests are sent to Google Fonts.
- Error monitoring (Sentry): When enabled, it does not set cookies; cookies and the device ID are removed from error reports.
- Affiliate: No affiliate cookies are set on the Hani website. When you move to a seller's website via "Go to seller", that seller and the affiliate network may use their own cookies on their own sites, under their own policies.
3.Legal basis
The cookies we use are strictly necessary to provide the service you request (so that your device-specific settings, your Premium membership and, if you are signed in, your session work). They are therefore processed under KVKK art. 5/2-c (performance of a contract) and 5/2-f (legitimate interest), and no separate consent is requested. If we add a cookie for analytics or advertising, we will update this policy and ask for your explicit consent first.
4.Managing cookies
You can view, delete or block cookies and site data in your browser settings. If you block the necessary cookies:
- a new anonymous ID is created on every visit, so your Premium membership, alerts and preferences may not appear in this browser,
- you cannot sign in, or your session will not stay open.
Signing out deletes the session cookie. To reset the device ID, clear this site's data in your browser; to have your data deleted from our servers, see Delete Account & Data.
