Rentroll
Your rent notebook, done right — mark paid, spot arrears, keep a 12-month register per unit
Add each room, floor or shop once with tenant, rent, deposit and move-in date. Each month, mark paid, partial or due, add electricity or water extras, and Rentroll computes what was collected, what is due and who is carrying arrears from earlier months. Free, offline, no account.
Stored in your browser only. Nothing you do in the web version is sent to our servers. Clear your browser data and it's gone — so export a backup from the in-app menu if you want to keep it.

Questions
Is the web version of Rentroll free?+
Yes. Sign in with a free All Things AI account and use every screen — no subscription, no in-app purchases.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Do I need an account?+
You can read about the app without one, but you must sign in to open it. Sign-in is free and takes a few seconds with Google.
How is the web version different from the Rentroll iPhone app?+
Records live in this browser only; export the CSV or a JSON backup to move them elsewhere.
