Last updated: 2026-06-13
This Privacy Policy describes how Nidus ("we", "us", "the app") collects, uses, and protects your information when you use Nidus.
Data we collect
- Account data: email address, full name (optional).
- Receipt data: photos of receipts you scan, and the line items, prices, store names, and dates extracted from them.

- Household data: the household you belong to and other members' names/emails, if you create or join a household.

How we use your data
