These terms cover using Rinn. They are deliberately short, because Rinn is a small app that records who owes what — it is not a bank and does not hold anyone's money.
Rinn records shared expenses and calculates who owes whom. It can open a payment app with an amount filled in, and it can record that you say a payment happened.
You are responsible for what happens under your account and for the accuracy of what you record. Do not use Rinn to record anything unlawful, and do not use it to store information about people who have asked you not to.
Adding someone by name means storing their name on a service they have not signed up for. Only add people you actually share costs with, and use the name they would expect to see. If they ask to be removed, remove them — or point them at Support.
Scanned receipts are read automatically and the result is often, but not always, correct. Check the amounts before saving. Rinn is not responsible for a split based on a misread receipt you did not correct.
Rinn is provided as-is, with no guarantee of uptime, and may change or stop. Receipt images are deleted on a schedule described in the Privacy Policy. Keep your own copy of anything you cannot afford to lose.
To the extent the law allows, Rinn is not liable for indirect or consequential loss, for money you did or did not send someone, or for a disagreement about who owes what. Nothing here removes rights that cannot be removed by agreement, including consumer rights you may hold locally.
Stop using Rinn whenever you like. The profile screen has both “Delete all my data”, which removes the trips and bills only you were in, and “Delete my account”, which additionally erases your name, contact details and payment handles and deletes your sign-in. Both happen in the app; neither needs an email to us.
Trips you share with other people survive either action, with your name removed — the expenses and balances in them are those people’s records too. Deleting your account does not settle or cancel money owed. The Privacy Policy sets all of this out in full, and Delete your Rinn account gives the steps.
Access may be withdrawn if the service is used to harm someone or to break the law.
These terms are governed by the laws of the State of Indiana, United States, and any dispute is subject to the courts located there.
