FAQ

Frequently asked questions

Is my data really private?

Yes. Your portfolio is encrypted on your device before it ever leaves it. We never see your positions or figures — and we don't want to.

Does it help with the Spanish tax return?

CompoundVision computes capital gains with statutory FIFO, savings-income tax and prepares Modelo 720. It's informational (it doesn't file for you), but it leaves everything ready for your accountant.

Do I have to connect my bank?

No. You can import via CSV or add manually. You decide what goes in. No aggregators selling your data.

What if I try it and it's not for me?

You start free. The calculators are free forever. And Pro comes with a 14-day no-questions refund.
