About the Project

A money-management app should improve your financial wellness and provide peace of mind. Aventurine is the most private personal finance app on the market. To acheive that, it uses the old-fashioned business model: An app that you pay for once and own forever. Which means it's completely offline - No enforced subscription license, no in-app ads, and no in-app purchases.

$100+ saved every year compared to leading subscription finance apps.

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. If you have been keeping a spreadsheet to track your finances because you refuse to pay a subscription to big tech, then Aventurine is here for you!

Where is my financial data stored?

Aventurine stores all of your financial data and preferences in a local SQLite database on your machine, encrypted with AES-256, the same encryption that banks and governments trust with their most valuable secrets. You have full control over how you store and back up your file, so you always have the access you need without compromising your security.

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 imports CSV, Excel, OFX, QFX, QIF, and JSON, covering what virtually every bank and finance app can produce. Exporting your data back out as CSV, OFX, QFX, or QIF is just as easy.
