Frequently Asked Questions

Who is Aventurine for?

Aventurine is for people who need a personal finance system with modern features but don't want to pay for expensive software that compromises their privacy and security.

Where is my financial data stored?

Aventurine stores all of your financial data in a local SQLite database on your machine. It's never uploaded, sent, or moved anywhere else.

Is Aventurine really free?

Yes. Aventurine is free to download and use during the beta period. A one-time purchase will be required after beta, and the price will be announced before that happens. Your data always stays on your machine regardless.

Which platforms are supported?

Windows and Linux at the moment. Your database file is portable between any of the available versions.

Can I import data from my bank or another app?

Yes. Aventurine supports all major import/export extensions (CSV, OFX, QFX, or QIF) covering what virtually every bank and finance app can produce. Exporting your data back out is just as easy.
