## Who publishes it

WhatIsMyIP.bz is operated by **Dynamic Foundries**, a French SASU
registered in Paris (RCS Paris 102 801 206). Portfolio: two revenue
products (FileSendX, ViewPeek) and a network of free utility tools,
of which WhatIsMyIP.bz is one.

## Privacy

Standard nginx access logs are kept for operational purposes
(security, abuse mitigation) and rotated. We do not build or sell
visitor profiles. The IP you look up is processed transiently and
not retained beyond logs.
