Proof

Proof is a lightweight attachment checklist app for daily work in India.

Use Proof to pick bill photos, receipt PDFs, delivery slips, office attachments, service photos, or fee proof files from the Android document picker, save their names and sizes as a local checklist, add a work note, and share a plain-text proof summary with your team.

Proof is built for everyday India workflows such as rent proof, shop bills, delivery evidence, fee receipts, counter handover, repair photos, supplier documents, and office attachment follow-up. Proof is not a generic file reader; it is a local checklist for selected attachment names, sizes, notes, and sharing.

Files stay local. Proof records only the selected file names and sizes for checklist use, does not request broad storage access, does not require an account, and does not upload selected files to a developer server.
