Trust and limits

We do not claim guaranteed legal compliance. Coded rules are documented in `/docs/domain-rules.md` and must be reviewed before any live sale.

Privacy in the MVP

Analytics only stores funnel steps, session ID, and UTM data. Documents are not uploaded, and form data is not persisted server-side.

FAQ

Is the statement legally binding?

Not yet as a sales promise. The MVP produces a transparent draft and marks it as TEST / DRAFT until the rules are independently reviewed.

Who is this for?

For private landlords with a few units who don't need a full property-management suite and can enter their numbers in a structured way.

Are receipts uploaded?

Not in the MVP. You can optionally note a document name; files are not stored.

Why does it cost €14.90?

That's the test price per statement. In validation mode nothing is charged; we only measure whether users reach the purchase decision.
