Is TopCashback UK Browser Extension safe?
TopCashback UK Browser Extension sends shopping-page DOM snapshots to api.onsleek.ai during coupon detection.
When its Sleek coupon feature runs, the extension serializes shopping-page HTML, page URL, page title, and browser user agent for coupon support checks and auto-apply. It also reports merchant names, coupon codes, coupon session IDs, order values, savings, and affiliate activation events to Google Analytics using a persistent analytics client ID.
