Every warranty, every return window, stamped.
ProofOF is the receipt tracker and purchase log app that turns a photo into proof. Snap the receipt, confirm retailer and serial, and the warranty expiration reminder and return window tracker start counting — offline first, encrypted at rest, synced only if you sign in.
Scan & Forget
01On-device OCR (Vision / ML Kit) reads retailer, date, price, and serial. The receipt photo backup stays with the entry — no retyping, no cloud OCR.
Window Watcher
02Return window tracker sorted by urgency. 7-day and 1-day pushes, optional calendar mirror, and retailer-aware windows (Amazon 30 days, Costco 90 days, Best Buy 15 days — you confirm).
Amazon / Costco / Target / Best Buy / Nike — any store's return policy, tracked.
Secure Archive
Encrypted receipt app with SQLite-first storage. Receipt photo, proof of purchase, and deadlines travel as one proof packet — offline receipt tracker until you sign in.
Lifetime warranty tracker & extended warranty
File lifetime warranties (Heritage Boots, cast-iron, tools) and AppleCare+ or extended warranties alongside 30-day returns. The warranty expiration tracker shows “Lifetime • Vaulted” where there is no end date — never a false deadline.
