A tool for bypassing time-based features of Family Link parental controls

How to use

Note

YOU NEED A COMPUTER AND DEVELOPER OPTIONS ENABLED FOR THIS TO WORK. DEVELOPER OPTIONS CAN BE ENABLED ON THE PARENT APP.

1. Download the appropriate release for your CPU architecture from the releases (The one you need is probably chronolink-aarch64).

2. Ensure you have adb installed on your machine

3. Connect your phone via USB

4. adb push chronolink /data/local/tmp

5. adb shell chmod +x /data/local/tmp/chronolink

6. List time zones with adb shell /data/local/tmp/chronolink list

7. Once you've chosen a time zone, you can set device time to it as so: adb shell /data/local/tmp/chronolink America/New_York

   Replace New_York with the time zone you choose from the list.

8. Enjoy bypassing downtime!

FAQ

Will this work with developer options off?

No.

Why do you have a file with every single time zone on Android? Is that not bloat?

Planning on removing it later lol

How do I compile?

Compiled on Ubuntu 24.04.1 LTS. This will assume you are using a debian-based distro, but this should work on most major distributions. The binder_rust crate relies on on the nix crate which is not supported on Windows right now.

First things first, make sure you have Rust and the android NDK ready. You can follow this guide for a walkthrough of how to set up both of those.

sudo apt install -y build-essential

git clone https://github.com/rifting/chronolink.git

cd chronolink

cargo build --release --target=<YOUR ANDROID TARGET>

Find your chronolink binary in target/<YOUR ANDROID TARGET>/release/chronolink
