## Description

Prove your music is original with one tap. Timestamp certificates, audio watermarks, and a verification portal -- all without uploading your files.

  Prove your creative work existed at a specific moment in
  time. STAMPiD creates cryptographic timestamps that are
  legally defensible, tamper-proof, and verifiable by anyone
  -- without ever uploading your files.

  Key Features:

  - Cryptographic timestamps backed by RFC 3161 authorities
  and Bitcoin blockchain anchoring
  - Your files never leave your device -- only the SHA-256
  hash is sent to the server
  - Professional PDF certificates with QR verification codes
  for sharing proof
  - Evidence folder exports with complete chain-of-custody
  metadata
  - Public verification portal so anyone can independently
  confirm your timestamps
  - Audio watermarking for musicians and podcasters to embed
  proof directly in recordings

  How It Works:
  Select any file on your device. STAMPiD computes a unique
  SHA-256 fingerprint locally and sends only that fingerprint
  to trusted timestamp authorities. You receive a signed
  certificate proving your file existed at that exact moment.
  The original file never leaves your device.

  Subscriptions:
  STAMPiD offers optional subscriptions to unlock higher usage
   limits:
  - Creator: $4.99/month -- 50 stamps, 25 watermarks, 25
  exports per month
  - Studio: $9.99/month -- 250 stamps, 100 watermarks, 100
  exports per month
  Payment is charged to your Apple ID account at confirmation
  of purchase. Subscriptions automatically renew unless
  canceled at least 24 hours before the end of the current
  period. You can manage and cancel subscriptions in your
  Apple ID account settings. Free tier includes 5 stamps, 3
  watermarks, and 3 exports per month.

  Privacy:
  Your files never leave your device. STAMPiD only transmits
  the cryptographic hash -- a one-way fingerprint that cannot
  be reversed to reconstruct your original content.
