## What is NoiseProof?

NoiseProof turns your iPhone into a court-ready evidence kit for neighbor, construction, and short-let noise disputes. One tap captures decibels, audio, GPS, and a tamper-evident PDF you can hand to a landlord, mediator, or attorney.

WHY NOISEPROOF
• Tenants document upstairs footsteps, parties, and yelling
• Owners document construction and short-let nuisance
• Lawyers and mediators get a structured, defensible record

EVERY RECORDING PRODUCES
• Real-time A-weighted dB(A) meter with per-iPhone calibration
• Lossless audio file kept on device — never uploaded anywhere
• Per-100 ms sample stream (dB, peak frequency, vibration)
• GPS fix with reverse-geocoded address (optional)
• 5-page evidence PDF: cover, methodology, dB curve, per-minute LAeq, disclaimer
• SHA-256 chain-of-custody footer and a separate .sha256 sidecar
• Comparison to the local nighttime/daytime noise ordinance

PRO FEATURES
• Unlimited recordings (free tier is 3 per month, 5 minutes each)
• Evidence PDF generation
• Sealed mode — recording becomes read-only inside the app
• GPS-anchored events
• Top-15 US city ordinance comparisons

PRO+ FEATURES
• Background trigger sentinel — captures the moment dB(A) crosses a sustained threshold
• iCloud sync across your iPhones and iPad
• Multi-event bundle PDFs
• Dispute message templates (friendly, formal, pre-litigation)

PRIVACY
• Audio is stored locally under File Protection: Complete
• No analytics, no ads, no third-party SDKs, no server
• iCloud sync (Pro+) is opt-in and uses Apple end-to-end encryption

LEGAL
NoiseProof produces measurement data — it does not give legal advice and does not guarantee admissibility. U.S. recording laws vary by state. Several states require all parties to consent before private conversations may be recorded. Verify local law and consult a licensed attorney before sharing audio. The app shows a recording-law warning on first launch.
