Hop — Privacy Policy

Last updated: 2026-10-29 · Publisher: ZenTao Studio

Hop is a network diagnostics toolkit (traceroute/MTR, ping, TCP ping, DNS, whois, LAN devices, Wake-on-LAN). Short version: Hop collects nothing about you. It has no account, no ads, no analytics and no crash-reporting SDKs, and it never asks for your location.

What Hop sends, and to whom

Hop only sends network traffic when you start a tool, and only to the destinations that tool needs:

Ping, traceroute, TCP ping, port scanner: probes to the host you typed.
DNS lookup: your question to the DNS server you chose (your network's, or a public one such as Cloudflare 1.1.1.1, Google 8.8.8.8, Quad9 9.9.9.9, OpenDNS, AliDNS).
Router names and network owner (ASN) shown in traceroute and IP info: reverse-DNS questions to your network's DNS server and DNS questions to Team Cymru's public IP-to-ASN service (asn.cymru.com) containing the router or host address.
"Show my public IP": one DNS question to OpenDNS (myip.opendns.com).
Whois: the domain or address you entered, sent to whois.iana.org and the registry it refers to.
Devices on my network: probes and name queries (mDNS, NetBIOS, reverse DNS) inside your own local network only.
Wake-on-LAN: a broadcast packet on your local network.

These are standard internet protocols answered by those operators under their own policies. Hop adds no identifiers of its own and Zentao Studio receives none of this traffic.

What stays on your phone

The hosts you used recently (to offer them again) and the Wake-on-LAN devices you saved. They never leave the device and are excluded from cloud backup. Settings → Clear recent hosts removes the history; uninstalling Hop removes everything.

Permissions

Internet and network/Wi-Fi state (to run the tools and show network info) and Wi-Fi multicast (to hear device names announced over mDNS). No location, contacts, storage or phone permissions.

Purchases

Hop Pro is bought through Google Play. Google processes the payment under its own privacy policy; Hop only learns whether the purchase exists.

Children

Hop is not directed to children under 13.
