Offline expense tracker (no network permission)- feedback welcome

indranilbhuin

I’ve developed a fully offline expense tracking app and would appreciate feedback from a GrapheneOS perspective. It does not request the INTERNET permission, has no network capabilities, no Play Services dependency, no accounts, and no telemetry. All data is stored locally on device. I’m mainly interested in whether there are additional hardening considerations or best practices I should follow when handling sensitive financial data on GrapheneOS. The project is open source on GitHub.

indranilbhuin is there anything wrong with old good moneymanagerex with strong community behind, cross-platform, offline etc?

Mind posting a link to the repo?

Sure. Here’s the repo: https://github.com/indranilbhuin/zero
It’s fully offline, no INTERNET permission, no Play Services dependency, no telemetry. Built specifically to have zero network surface.

littlerack not the dev but... Why not? We have more than one app for all things possible, maybe they serve different people? :)

Nothing wrong with it. Different scope.
I built this as a mobile-first, zero-network app with strict minimal permissions. It’s a different design philosophy, not a replacement project.

littlerack

chinook you misinterpreted the purpose.
1, as the topics has appeared, it's to remind to the interested that moneymanagerex exists for the purpose
2, to indirectly reference an old meme re (-1) "there are already 23 wrong standards that describe X, thus I introduce a new one that is better than those 23"; (now)" there are 24 standards "

Fair analogy, but this isn’t about introducing a new “standard.” It’s about tightening constraints. When you remove network capability entirely, a lot of architectural decisions simplify in interesting ways.

Why would anyone recommend official abandonware since 2024?

It looks good. My focus here is eliminating the network stack completely. If an app can’t make outbound connections at all, the threat model shifts significantly.

Long-term maintenance matters for financial software. That’s exactly why I kept the codebase lean and transparent.

littlerack what is there to add to a glorified spreadsheet?
There are thousand of budgeting apps trying to reinvent the wheel and people flooding the market trying to monetize their student projects unsuccessfully, this is one of the rare ones that look good to me and if push comes to shove I can always fork the project since it is open source.

Feel free to recommend us an alternative then.

There is no accounts, there is no loans tracking, categories are flat instead of nested/tree... not for me

True, besides the last release is 7 months ago--not 24.
