VPN leak detector

Build a tool that tests Android VPNs for NAT-T keepalive leaks. Help users verify their privacy.

Why now

New research shows Android VPNs can leak data through NAT-T keepalive bypasses.

Who for
Privacy-conscious Android users
Business model
Freemium app with paid features
Effort
A few weeks

Many Android users rely on VPNs for privacy, but NAT-T keepalive bypasses can leak data. A detector app could simulate network traffic to identify leaks.

Monetize through a freemium model with basic free tests and advanced diagnostics behind a paywall.

Start with NAT-T testing. Expand to other VPN vulnerabilities later.

Risk: VPN providers may patch issues faster than the tool can adapt.
