I built a browser-only checker that classifies Bitcoin addresses by likely quantum exposure. It inspects spend history and script type via public Esplora endpoints (you can select your own) and supports batch lookups plus custom endpoints. Let me know if you like it

nice try with this bullshit scam
You can check the code here https://github.com/j-sokol/btcq that it is not scam, nothing is logged, u can also select your own Esplora endpoint and then nothing will be sent out from your local network.
