LLM Policy

This is a complex app that relies on interfacing with obscure Android APIs and is thus hard to test and verify. This makes it a poor match for agentic workflows and their use for contributions is heavily discouraged.

Please do not use LLMs for generating issues and pull request descriptions. They are not capable of providing any extra useful info and just make the whole thing harder to read. Instead use the predefined feature request/bug report templates.

If the policy is not followed you will receive a warning and on second strike be permanently banned from contributing to this project.

Code

Contributors are welcome, however please create an issue first. When asking/adding features please elaborate why that feature is useful to you.

How Shizuku is used

Can track mobile data separately for each SIM via a `Shizuku user service`.

This is an AI-assisted analysis of Shizuku-related usages in the app's public source code. It is best effort, so it may not catch every single usage.

How this app uses Shizuku

Shizuku is used to enable multi-SIM data tracking by reading SIM identity information the app cannot normally access.

Track data per SIM: with Shizuku enabled, the app looks up the active SIMs in each slot with their carrier names and reads a hidden subscriber identifier for each SIM through a privileged system service, then links each mobile data plan to the correct SIM so usage, limits and warnings stay with the right card when SIMs are swapped or added.
