Cakebyte: No-Root Firewall

Cakebyte is a no-root firewall that puts you back in control of your Android's network. See exactly what every app connects to — including the trackers working in the background — and block any app from WiFi or mobile data with a single tap.

Most firewalls quietly drop blocked traffic, which leaves apps retrying over and over in the background. Cakebyte actively shuts those connections down, so blocked apps fail fast — saving your battery and your mobile data instead of wasting them.

Everything happens on your device. No accounts. No cloud. No data collection. Cakebyte even ships with zero third-party code, so there's nothing in it that could quietly leak your information.

— WHAT YOU CAN DO —

• Block any app from WiFi and/or mobile data, independently, in one tap

• See a clear, live log of every connection each app makes

• Spot trackers automatically — and tap any connection to block that IP for every app

• Keep a global blocklist of IP addresses or ranges (IPv4 and IPv6)

• Review daily activity: how much each app tried to connect, and how much was blocked

• Get alerts for unusual events, like a VPN conflict or a revoked permission

— WHY CAKEBYTE —

• No root required — works on any device running Android 10 or newer

• Active blocking, not silent dropping: blocked apps fail fast and stop draining battery

• Built to stay out of the way of streaming — no audio or video stutter with the screen off

• Truly private by design: runs only on your device, collects nothing, talks to no servers

• Zero third-party dependencies — a smaller, more trustworthy attack surface

• A clean, modern interface that's actually pleasant to use

• One-time purchase. No subscription. No ads. You're the customer, not the product.

— IS THIS A VPN? —

No. Cakebyte uses Android's local VPN slot only to filter traffic on your own device. Nothing is tunneled anywhere — there are no servers, no remote endpoints, and your traffic never leaves your phone. It's a firewall, not a proxy or an anonymizer. Because Android requires the VPN permission to filter traffic without root, that's the only reason you'll see the VPN icon.
