Meilero – Miles & Cashback while shopping de Kolja

Meilero shows whether the online shop you're visiting has an active miles or cashback offer (e.g. Miles & More, Payback) and gives you the correct activation link.

Privacy-first: matching happens entirely offline on your device — only the domain is checked against a locally cached catalog; your URLs never leave your device. Discreet toolbar badge + popup; the optional in-page banner is off by default and requests host access only when you enable it. No auto-clicks, no hidden cookies, no telemetry.
