Cakebyte: No-Root Firewall

Cakebyte is a firewall for Android that doesn't need root. It shows you what every app on your phone is talking to, including the trackers running in the background, and lets you cut any app off from WiFi or mobile data with one tap.

When you block an app, it helps if the app knows about it. Otherwise it keeps trying in the background, over and over, quietly using up battery and data. Cakebyte answers those blocked connections instead of leaving them hanging, so the app gives up straight away and your phone gets to rest.

Everything runs on your phone. No account to make, no cloud, nothing collected. No analytics, no ad network, no crash reporting. The only part of Cakebyte that touches the internet is Google's billing library, and only when you buy Pro.

FREE, AND STAYING FREE

• Block any app from WiFi, mobile data, or both, in one tap
• Decide what happens if the firewall stops: bring it back, or cut the network until it is back
• Keep streaming smooth with the screen off, even on long sessions
• Lock Cakebyte behind your fingerprint or PIN
• Turn connection logging off completely if you would rather nothing was recorded

WITH CAKEBYTE PRO

• Watch a live log of the connections each app makes
• See which of those connections are trackers, and tap one to block that IP everywhere
• Keep your own blocklist of IPs and ranges (IPv4 and IPv6)
• Check the day's activity: what each app tried, and what got stopped
• Get an alert when something odd happens, like another VPN taking over or a permission being revoked

WHY CAKEBYTE

• No root needed. Works on anything running Android 10 or later.
• Blocked apps stop trying quickly, so your battery and data go further
• Your data never leaves the phone. I don't run a server, so there's nowhere for it to go.
• No ad or analytics SDKs bundled in
• An interface that's nice to look at and quick to get around
• Pay once. No subscription, no ads.

IS THIS A VPN?

No. Android won't let an app filter traffic without root unless it takes the VPN slot, so that's what Cakebyte does, and that's the only reason you'll see the VPN icon in your status bar. Nothing gets tunneled anywhere. There are no servers on the other end, and your traffic never leaves the device. Cakebyte filters, it doesn't relay, and it won't hide your IP from anyone.

PRIVACY

No personal data is collected. It all stays on your phone. You can read the full policy at https://twius.github.io/Policies/cakebyte/ or in the app under Settings > About > Privacy policy.

Blocking apps is free and stays free. Pro is free for the first 14 days, then a single purchase and it's yours for good.
