Frequently asked questions
Email support@proofspin.app if yours isn't here. Help with the app itself is on the support page.
Will a rental company or my card issuer accept it?
Nobody has to accept any evidence, and ProofSpin can't promise how a dispute ends. What it gives you is a complete record they can check for themselves: about 80 sharp photos covering every side from one walk, a fingerprint for every original, the time of the walk signed by ProofSpin's server clock, and an independent timestamp made at pickup. Anyone you send the link to can turn the car, zoom in and check that each photo matches the original sealed at pickup. Open the sample inspection.
Why not just film a video?
A frame from a walkaround video is about 2 MP at the iPhone's default 1080p, compressed and blurred as you walk, so a fine scratch is often a smear. Nothing tells you that you missed a side, and weeks later the video is somewhere in your camera roll. A ProofSpin walk takes 12 MP photos, checks every side before you stop and keeps both walks of the rental together. See the comparison.
How long does a walk take?
Under a minute for most cars. Walk once around the car at your own pace; the app takes a photo every few degrees and tells you before you stop if a side is missing. Close-ups of existing marks and a photo of the agreement take a little longer.
Does it work with no signal, like an underground parking garage?
Yes. The walk, the photos and the seal are all made on your iPhone, and the flashlight turns on when it's dark. Without a connection the app can't ask ProofSpin's server clock for the time, so that walk shows your phone's clock and says so.
What happens to my photos?
They stay on your iPhone. You don't sign in, and ProofSpin never asks for your name, email or phone number. Sealing a walk sends only a fingerprint of the record, a short code that can't be turned back into your photos. Photos go to the cloud only if you put an inspection there, and your rental agreement is never on a shared page. Read the privacy policy.
Do I need an account?
No. There's no sign-up, for the free first rental or after it. If you use the cloud, the app creates an anonymous account by itself and keeps it in your iCloud Keychain.
What does it cost?
Your first rental is free: the pickup walk and its return, kept on your phone. After that, a one-off unlock covers every later rental on your iPhone, and you pay for cloud only if a bill arrives and you need to send the evidence. See all prices.
I already have a bill and didn't use ProofSpin. Can it help?
Not with that rental. A record is sealed when you walk, so photos already in your camera roll can't be given a pickup time afterwards. Send the rental company what you have, and walk the next car before you drive off.
Which phones does it work on?
ProofSpin is an iPhone app and needs iOS 17 or later. The people you send a link to can open it in any browser, on any phone or computer, without installing anything.
Which vehicles can I walk around?
Cars, motorcycles and scooters, and RVs and camper vans. A walk from the ground can't see an RV's roof, so ask for the roof's condition to be written on the pickup sheet. ProofSpin for RV and camper van rental.
What if I lose or replace my iPhone?
Inspections in the cloud come back on the new iPhone. Inspections kept only on the old phone don't move, because ProofSpin leaves them out of device backups, so put the ones you need in the cloud first. Moving to a new iPhone.
For iPhone. Your first rental is free.
