Privacy
This site sets no cookies and runs no analytics or tracking scripts. GainPool reads, computes and stores your transaction data on your own machine; we operate no server that receives it. Licensing, updates and the operating system's own webview do contact external services — set out in full in the application.
Not tax advice
GainPool is a calculation aid. It produces an estimated Capital Gains position from the records you give it, does not submit anything to HMRC, and is not a substitute for advice from a qualified accountant.
