The website loads the Google Tag Manager container with analytics and advertising consent denied by default. Fetching a file from Google may transmit connection information such as your IP address. Only after you confirm analytics may a configured Google Analytics tag measure page views, product interactions and the ordering journey. TECHBUY does not send names, phone numbers, email addresses or OTPs to Google Analytics. Declining does not affect your cart or checkout.

Advertising is a separate choice for advertising or remarketing tags configured in Google Tag Manager. TECHBUY will update the provider inventory before enabling additional advertising tags or third-party pixels. Video is preferentially embedded through YouTube’s no-cookie domain.

Analytics and advertising choices are stored as techbuy-cookie-preferences-v2. Optional choices take effect only after you confirm. With analytics consent, source attribution is kept as techbuy-attribution-v1 for up to 30 days. You can change your choices in the footer or clear browser data.

Declining optional categories does not remove unrelated core functions.

Cookie questions: cskh@techbuy.vn or 0981112112. TECHBUY reviews this list whenever a provider, duration or purpose changes.
