Read full description

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.
