Pocket Proof — Privacy Addendum
This addendum supplements the Dignity Labs Base Privacy Policy. It details what data Pocket Proof specifically collects and how it is handled.
Pocket Proof is 100% local. There are no accounts, no cloud storage, no network calls, and no backend. Your recordings never leave your device unless you explicitly choose to share them. Dignity Labs Ltd has no access to your data.
| Characteristic | Detail |
|---|---|
| Accounts | None. No sign-in, no registration. |
| Cloud storage | None. All data on your device only. |
| Network calls | None during normal operation. RevenueCat SDK validates subscriptions (see PP10). |
| Backend servers | None. Dignity Labs does not operate servers for Pocket Proof. |
| Data processor | None. We do not process your data. |
When you use Pocket Proof, the following data is captured and stored on your device only:
| Data Type | When Captured | Storage | Leaves Device? |
|---|---|---|---|
| Video recording | When you record video | Device filesystem | Only if you share |
| Photo | When you take a photo | Device filesystem | Only if you share |
| Audio | When you record audio (standalone or with video) | Device filesystem | Only if you share |
| SHA-256 hash | Immediately on capture | JSON metadata on device | Only if you share |
| GPS coordinates | At moment of capture | JSON metadata on device | Only if you share |
| GPS accuracy | At moment of capture | JSON metadata on device | Only if you share |
| Timestamp | At moment of capture | JSON metadata on device | Only if you share |
| Device make and model | At moment of capture | JSON metadata on device | Only if you share |
| Operating system | At moment of capture | JSON metadata on device | Only if you share |
| Hashed device ID | At moment of capture | JSON metadata on device | Only if you share |
| Chain of custody log | On every action (capture, view, export, share, delete) | JSON metadata on device | Only if you share |
| Evidence notes | When you add notes to a recording | JSON metadata on device | Only if you share |
| Evidence stamp name | When Pro user enables stamp | JSON metadata on device | Only if you share |
In addition to your recordings, the following is stored on-device only:
Dignity Labs Ltd does not collect, receive, process, store, or have access to:
We literally cannot see your data. There is no technical pathway for your Pocket Proof data to reach us.
Pocket Proof requests the following device permissions:
| Permission | Purpose | Required? |
|---|---|---|
| Camera | Record video and take photos | Yes (core function) |
| Microphone | Record audio with video and standalone audio capture | Yes (core function) |
| Location (foreground) | Tag captures with GPS coordinates | Optional — enhances evidence |
We do not request access to your contacts, photos library, calendar, or any other data on your device. Location permission is requested for all users and only while the App is in use (foreground only).
When you export or share a recording from Pocket Proof:
Pocket Proof uses AES-256-GCM encryption to protect sensitive data stored on your device, such as trusted contact details. The encryption key is derived from your PIN and stored in your device's secure hardware (iOS Keychain / Android Keystore). Dignity Labs Ltd does not have access to the encryption key or the encrypted data. Evidence recordings and metadata are stored unencrypted on your device's filesystem, protected by your PIN and device security. If you lose your device or forget your PIN, encrypted data cannot be recovered.
Trusted contacts are names and phone numbers you enter manually into the App for quick sharing. They are stored on your device only, encrypted with AES-256-GCM, and are never transmitted to any server. They are not synced with your device's address book. Deleting the App or clearing App data deletes your trusted contacts permanently.
Pocket Proof uses no third-party services for evidence storage or processing. The following third-party services are involved in app distribution and subscription management:
| Service | Purpose | Data Involved |
|---|---|---|
| Apple App Store / Google Play Store | App distribution and payments | Managed by Apple/Google, not by us |
| RevenueCat | Subscription management and purchase validation | Purchase tokens, subscription status, and a one-way hashed device identifier for fraud prevention. No personal information, no evidence data, no location. See RevenueCat Privacy Policy. |
There is no Supabase, no analytics service, no crash reporting, and no ad network.
Pocket Proof includes a diagnostic report feature accessible by tapping the version number five times in Settings. This generates a report containing device information, app permissions, security status, storage statistics, and error logs. The report is shown to you in full before sending. It is sent via your device's email app — Dignity Labs does not receive it unless you choose to email it to us. No diagnostic data is collected automatically.
| Data Type | Retention |
|---|---|
| Free tier recordings | Auto-deleted after 24 hours |
| Pro recordings | Retained until you delete them or configure auto-delete |
| App settings | Deleted when you uninstall the App |
| PIN | Deleted when you uninstall the App |
| Trusted contacts | Deleted when you uninstall the App |
To delete all Pocket Proof data: Uninstall the App. Since all data is on your device and Dignity Labs holds none, uninstalling permanently deletes everything. There is no server-side data to request deletion of.
Because Pocket Proof stores no data on any server, a breach of Dignity Labs infrastructure would not affect your Pocket Proof data in any way. Your recordings, metadata, and settings exist only on your device.
Your GDPR rights are set out in the base Privacy Policy. In practice, because Pocket Proof collects and stores no personal data on our servers, many of these rights (access, rectification, erasure, portability) are satisfied by the fact that we hold no data about you. If you contact us to exercise a right, we will confirm that we hold no Pocket Proof data.
