Free vs. Paid — What's the Difference?

Flux has a Free plan and paid plans (Standard and Advanced).

Free puts you in Sandbox mode, where you can use much of the same core functionality as paid plans to get a general look at your income — add sources, enter numbers, and see how things add up. It's just not as accurate or detailed as tracking real income, and a couple of features are reserved for paid plans: the Time Off Bank and Reports.

Paid plans unlock the full app: real income sources, logging actual earned income, auto-log from pay stubs, the Time Off Bank, Reports (Income Report and Annual Tax Overview), tax estimation, and jump-starting your year with income you already earned before joining Flux. Standard plan supports up to 3 active income sources.

If you started on Free, any sources you set up in your Sandbox carry over when you upgrade — you don't have to rebuild them from scratch.

Once you're on a paid plan, Sandbox mode doesn't go away — it stays available any time from a dedicated Sandbox link in your sidebar, so you can keep exploring hypothetical scenarios alongside your real tracking.
