What cookies are
Cookies are small text files that a site stores in your browser to remember your settings and behavior between visits. On OneCatalog we use cookies and similar technologies (localStorage, sessionStorage) only to operate and improve the service.
Categories we use
1. Necessary (technical)
The site does not function without them:
oc_lang— selected interface language (ru / en)oc_api_key— selected API key for catalog requestsoc_consent— your cookie consent (this document)oc_favorites— list of favorite productsoc_compare— comparison list
This data is stored locally in your browser, never sent to our servers or to third parties. We do not ask consent for these — without them the site cannot operate.
2. Analytics
Help us understand how users interact with the site: which pages are popular, which filters get used, where users drop off. Data is used to improve UX and does not allow identification of a specific person.
Analytics is enabled only with your explicit consent. Default is off.
3. Marketing
Not currently used. Reserved category for future retargeting / ad pixels. If we ever add them, it will be opt-in only.
