About carseal
carseal is an independent app that guides a rental-car photo walk-around at pickup and return, stores hashes of uploaded photos, and flags possible marks for review — so renters have dated photos to challenge a charge. AI can miss damage. carseal is not affiliated with, endorsed by, or paid by any rental company.
What carseal does
A guided walk-around scan at pickup and again at return. Kept photos are SHA-256 hashed into a Merkle tree, server-signed, and may receive an RFC-3161 timestamp token, then appended to an append-only custody log. An AI before/after comparison flags possible changes for review — where it is unsure, it treats the mark as pre-existing. Hidden or poorly lit marks can be missed. The PDF includes a public page that checks the stored hash record, not live file bytes.
Who writes this
carseal is built and written by Andi Blindu, its founder — the same name that appears as the seller on the App Store listing. The guides and FAQ carry that byline because consumer-rights content should say who stands behind it, not hide behind a brand voice.
carseal is independent: not affiliated with, endorsed by, or paid by any rental company, and it takes no commission on a dispute outcome. If a page here is wrong, the correction address below reaches the person who wrote it.
How our guides and FAQ are researched
The guides and the FAQ are written and maintained by the founder. Every legal or policy claim is checked against a primary source before publication — card-network dispute rules (Visa, Mastercard, American Express reason codes), rental companies' own published terms and deposit policies, and consumer-protection resources such as the European Consumer Centres Network and the US FTC. Where practices vary by country or company, we say so rather than generalise.
Pages carry a visible "Updated" date. When a rule changes — a reason-code revision, a deposit-policy change — we update the page and the date, not just quietly edit it.
