At the moment the Add-in is locally installed and only available for MS Excel on windows PC. This allow for top performance and privacy since you do not have to share your credentials. We have plan to make the most used functionality, portfolio tracking and tax payment, available for other online spreadsheet.

We get revenue with M/Y subscriptions and with Exchange fee rebates

Fell free to try the Add-in or to ask other questions
