FAQ
Straight answers
Is LoomLease free?
Yes. Every tool here is free to use, with no account, no trial and nothing to install.
Do I need to sign up?
No. There is no login. Open a calculator, type your numbers, and the answer is on the screen.
Is this legal advice?
No. LoomLease is not a law firm. The calculators do the arithmetic; your lease and your state’s law decide what actually applies. When money or a deadline is at stake, check with a local attorney or a tenant or landlord association.
