Privacy Policy
Last updated: August 24, 2026
KeyProof is a property walkthrough app that helps renters and buyers document the condition of a home with photos, video, voice notes, and a timestamped PDF record.
KeyProof is published by Cedarline Technologies LLC. Questions: contact@keyproof.app.
1. The short version
- Everything you create in KeyProof stays on your iPhone.
- KeyProof does not upload your walkthrough media to any server.
- Sign in with Apple is optional. Only your name (for the PDF signature line) and an opaque Apple user ID are received.
- No third-party analytics or advertising SDKs.
2. What we collect, and why
On-device data (never leaves your device)
| Permission | What we do with it |
|---|---|
| Camera | Capture photos and video clips of rooms |
| Microphone | Record voice notes about rooms or damage |
| Speech recognition | Transcribe voice notes inline (Apple on-device when available) |
| Photo library | Optional: import a listing photo from your camera roll |
| Location | Optional: stamp the property's address on the PDF cover |
| Calendar | Optional: write move-in or closing-day reminders |
| Notifications | Optional: local follow-up reminders |
We do not transmit any of the above off your device.
Apple Sign in (optional)
Apple shares your name (first sign-in only) and an opaque user identifier. We do not request your email address.
To revoke: iOS Settings → Apple ID → Sign-in with Apple → KeyProof → Stop Using.
Optional cloud backup (v1.1+, off by default)
Starting in v1.1, KeyProof offers optional metadata backup to a Cedarline-controlled Supabase project. When enabled: property list metadata (addresses, notes, price, agent contact) syncs. Photos, videos, and voice notes never sync — they stay device-local. Disable anytime in Settings → Account & privacy. Rows are gated by Row Level Security on your Apple user ID.
3. What we do not collect
- No photo uploads
- No contacts, messages, or browsing history access
- No selling or sharing with third parties
- No ads or advertising SDK
- No tracking (no IDFA, no fingerprinting)
4. PDFs you generate
Render on your device. Where they go next is your choice — Save to Files or share via the iOS share sheet (Apple-operated).
5. Deleting your data
Settings → Account & privacy → Delete account & all data wipes every property, walkthrough, capture, document, and profile. Also signs you out of Apple Sign in and deletes any cloud backup data.
For deletion requests that can't be completed in-app, email support@keyproof.app — we respond within one business day.
6. Children
Not directed at children under 13. Age rating 4+ but use case is for legal adults.
7. Changes to this policy
Material changes will bump the "Last updated" date at the top.
