ScratchProof guides you around a rental car in 6 angles at pick-up and at return, stamps every photo with the time and place, and seals each scan with a fingerprint. At return it shows what changed, then turns it into a PDF report and a ready dispute letter.

1Pick-up

Six angles, about 40 seconds.

Walk around the car before you drive away. ScratchProof shows you each angle, and you tap any scratch, dent or scuff to mark it. Every photo is stamped with the time and place.

2Return

See what changed at return.

Do the same six angles when you hand the car back. ScratchProof puts each angle side by side, shows what was already there at pick-up and points out areas that changed. You keep the real damage and remove the rest.

What it does

Everything ScratchProof does, in short.

1

Guided in 6 angles

Front, both sides front and rear, and the back. ScratchProof shows you where to stand, and you tap any scratch, dent or scuff to mark it.

2

Sealed with time and place

Every photo is stamped with when and where it was taken, and each scan is sealed with a SHA-256 fingerprint. Any later change breaks the seal.

3

See what changed

At return, ScratchProof compares each angle with pick-up and points out areas that changed. You keep the real damage and remove the rest.

4

Report and letter

Export a PDF condition report anyone can check at sintios.com/verify, and send a ready letter to the rental company, your card issuer or a consumer body.

5

Private by design
