Eugenius is built by Eugenius Enterprises LLC ("we", "us"). We take a privacy-first, local-first approach: your financial data lives on your own computer, not on our servers. This policy explains what limited information we do collect through our website and services, and how we use it.
The Eugenius desktop application stores your financial data (transactions, accounts, tax information, invoices, holdings, etc.) locally on your device in a private database. We do not receive, access, or store this data, except for the optional features described below that you choose to enable.
Payments are processed by our authorized payment provider, which collects and processes your billing information under its own privacy policy. We receive only the information needed to activate your subscription and provide support (such as your name, email, and order details). Your card details are not stored on our systems.
If you enable Cloud Sync or send documents for e-signature, the relevant data you choose to sync or send is transmitted to and stored on our secure cloud service to provide that feature. These features are optional and off by default.
Cloud Sync keeps a rolling 90-day copy of the transactions, account names, balances and invoices it syncs, so the mobile app has something to show. It is a copy, not the original: your books on your own computer remain the record, and if our copy vanished you would not lose a transaction.
If you choose to connect a bank or card account, that connection is made through Plaid, a third-party service that specializes in bank connectivity. You enter your bank credentials with Plaid, not with us, and we never see or store them. Plaid returns your transactions and balances, which are stored in the app on your computer.
This feature is optional and off by default. You can disconnect an account at any time in the app, and Plaid handles your credentials under its own privacy policy.
The app can use AI to read a scanned receipt or invoice and to answer questions about your finances. These features are optional, and you choose which AI they use:
What gets sent is the document you chose to scan, or your question together with the figures needed to answer it. We do not use your financial data to train AI models.
If you email us, we keep your message and contact details to respond and improve support.
We do not sell your personal information. We share it only with service providers that help us operate, and where required by law. Those providers are:
We keep personal information only as long as needed for the purposes above. You may request access to, correction of, or deletion of your personal information by emailing support@eugenius.ai. Because app data is stored locally, you control it directly and can delete it on your device at any time.
We use reasonable technical and organizational measures to protect information. No method of transmission or storage is 100% secure, but keeping data local by default substantially reduces exposure.
Eugenius is not directed to children under 16, and we do not knowingly collect their information.
We may update this policy; the "Last updated" date will change accordingly. Material changes will be reflected on this page.
