Question 1

Is my lease text uploaded to a server?

Accepted Answer

No. All analysis runs entirely in your browser using JavaScript. Your lease text never leaves your device and is never sent to any server. You can even disconnect from the internet after loading the page and it will still work.

Question 2

What lease clauses does this tool check for?

Accepted Answer

The scanner checks for 40+ patterns including: landlord entry without notice, automatic rent increases, non-refundable deposits, waived right to sue, jury trial waivers, rent acceleration clauses, early termination fees, auto-renewal clauses, subletting restrictions, excessive late fees, joint and several liability, mandatory arbitration, landlord liability waivers, lien on personal property, and more — each with a plain-English explanation.

Question 3

Is this legal advice?

Accepted Answer

No. This tool is for informational purposes only and does not constitute legal advice. Results are based on pattern matching and may miss context-specific nuances. Always consult a qualified attorney before signing a lease, especially if the tool flags multiple high-severity issues.

Question 4

What is the Lease Health Score?

Accepted Answer

The Lease Health Score is a number from 0 to 100 indicating overall lease fairness. It starts at 100 and is reduced by 15 points per High severity flag, 7 points per Medium flag, and 3 points per Low flag. Scores of 80–100 are good; 60–79 have some concerns; 40–59 are significant concerns; below 40 suggests you should consult a lawyer before signing.

Question 5

Which countries does this work for?

Accepted Answer

The scanner works best for leases written in English from the US, UK, Canada, and Australia. The pattern library is based on common Anglo-American lease language. Legal standards vary by jurisdiction — a clause flagged as potentially illegal in one state may be legal in another. Always verify with local tenant rights resources.
