Your lookups are yours.

IP Lens keeps the request path direct and understandable. It does not operate its own lookup backend.

device → provider

Requests go directly from your device.

Free IP lookups go to ipwho.is; personal-key lookups go to ipwhois.pro. DNS queries go only to the selected Cloudflare or Quad9 resolver, while registration queries go directly to the authoritative RDAP registry.

03Is IP Lens a subscription?

No. IP Lens is intended to be a one-time App Store purchase.

06Is IP geolocation exact?

No. IP geolocation is an estimate and may not represent a device's physical position.
