iPhone
A privacy-first camera that auto-blurs faces and changes voices in real time. Built for property tours, depositions, and field press work. Nothing leaves your phone.
Dossier is a privacy-first iPhone camera for the three jobs where pointing an
unredacted lens at a person is a real problem: real estate, legal, and journalism.
Faces blur in real time. Voices pitch-shift before the audio is even written to the
file. Nothing ever leaves your phone.
FOR REAL ESTATE AGENTS
Walk a listing without filming the seller, their kids, or the family photos on the
wall. Every face in frame is mosaiced as you record — including the buyer who just
walked into your shot. Drop a manual blur box over a license plate or personal mail.
Name each clip in your library ("412 Maple — kitchen") and sort by listing, client, or
date.
FOR PARALEGALS AND INVESTIGATORS
Capture a witness statement with the speaker's voice pitch-shifted from the moment of
capture, so no unredacted audio is ever stored. Every export carries a SHA-256
fingerprint you can prove later in court — show months from now that a copy is
bit-for-bit identical to the original, or prove it isn't. Live captions burn into the
recording for transcription. Lock the library behind Face ID.
FOR JOURNALISTS
Bystanders auto-blur so a source isn't compromised by being in your B-roll. Mark Region
covers anything the auto-pass missed — a badge, a door number. The Safety Pass
re-scans your finished clip for faces detected at frame edges. Everything happens
locally — no servers, no telemetry, no third-party SDKs.
WHAT DOSSIER DOES
• Real-time face blur — baked into the file, no unredacted version is ever stored.
• Voice change — pitch-shifted before audio is written.
• Live captions — on-device speech recognition, burned into video.
• Tamper-evident receipts — SHA-256 fingerprint + audit PDF for every export.
• Dual-aspect & dual-camera — portrait + landscape in one take, or front + back
simultaneously.
• Mark Region — manual blur box over anything missed.
• Safety Pass — second-look scan for missed faces.
• Photos too — stills get the same face-blur pipeline.
• Import & redact existing footage from your Photos library.
• Titles & tags — built for libraries past a hundred clips.
PRIVACY
• No accounts. No sign-up. No analytics. No ads.
• No network access of any kind. Dossier has no servers.
• Face detection, voice change, captions, hashing — all run on-device.
• Face ID / passcode lock optional on the library.
REQUIREMENTS
• iPhone running iOS 17 or later.
• Multi-camera and dual-aspect need iPhone 11 or later.
A NOTE ON LAWFUL USE
Recording laws vary by jurisdiction. Many places require all-party consent for private
conversations. Dossier shows a one-time disclaimer on first launch — lawful use is your
responsibility. The redaction features are a defense-in-depth tool, not a substitute
for consent.
