A written guarantee is a published rule, not a slogan in a footer.
If a payment we got wrong causes a fee, the written guarantee is the document that says we cover that fee. It is not a vibe. It sits next to the four dated stops because those stops are how you prove what happened. Scheduled, Debited, Delivered, Confirmed: each dated, each downloadable. The guarantee reads against that record.
You should not pay a late fee because our rail misfired. The file is the argument.
What it covers: fees caused by a payment we got wrong. What it does not cover: a debit that failed because your account could not fund, a date you changed after the window, or a property that charges for reasons that have nothing to do with Nopona. Failed funding pauses the schedule. That pause is visible. You fix the account. The rail resumes. That is a stopped payment, not a wrong payment.
Who it is for: renters who pay from the app, including Free. Free is $0: rent by transfer no fee, three bureau reporting, owner funded Rent Credit when the building is in network. Membership is $39 a year or $4.99 a month for out of network and roommates. Building is $5 per occupied unit per month. The guarantee is not a paid add-on. It is part of paying on this rail.
Read it before the first debit. Then check the building. Then schedule. Legal pages live at /terms-of-service. Compare plans at pricing. Dated proof, then a written rule about our mistakes.
