Privacy Cleaner SaaS — browser data deletion platform launched in 6 weeks

M3CA identified a gap in the consumer privacy market: most browser-cleaning tools were either bloated desktop software or unreliable browser extensions. The brief was to build a lightweight, credit-based web app and companion desktop agent that cleared cookies, cache, browsing history, and ad-tracker fingerprint data across Chrome, Firefox, Edge and Safari — all with a dead-simple interface deployable in under 6 weeks.

M3CA designed and built cleaner.m3ca.com end-to-end: a React-based SaaS web app with Supabase authentication, a Stripe credit-purchase flow (from £0.99), a real-time usage log dashboard, and a downloadable desktop companion app for deep system cleaning. The brand identity was built around a single value proposition — 'Protect Your Privacy. One Tap.' — with a dark, minimal UI that conveyed trust and speed. M3CA also integrated browser-specific cleaning APIs and built a tracking-prevention module targeting ad-tech fingerprinting scripts.
