Frequently asked questions
Are these really free?
Yes — no account, no email wall, no trial to start. They run in your browser or on our servers and give you the answer. The only one that touches our AI budget is the lease audit, which is capped at three uploads a day per person.
Do you keep the lease I upload to the audit tool?
The file is processed to produce your audit and is not used to train any AI model. See the privacy policy for the full data-handling picture.
Is the legal information reliable?
The deposit deadlines cite the governing statute for each state and carry the date they were last verified. They're a well-researched starting point, not legal advice — statutes change and cities layer on their own rules, so confirm anything you're about to rely on in a dispute.
What's the catch?
There isn't one, but there is a reason: these are the questions landlords search at the exact moment the spreadsheet stops coping. If a calculator saves you an argument, the product that keeps the whole ledger straight is one click away.
The tools are free. The bookkeeping is the product.
