SHA-256 Dashcam App for Proof: Hawk by MRVL
Hawk by MRVL is a dashcam app that records driving footage with SHA-256 integrity hashes on every clip, creating cryptographically verified evidence you can submit to insurance companies, police, or court.
What Is SHA-256 Hashing in a Dashcam?
SHA-256 is a cryptographic hash function that creates a unique digital fingerprint for each video clip. When Hawk records your drive, it writes a SHA-256 integrity hash to every clip, proving that the footage has not been altered or tampered with after recording. This hash is evidence-grade. If you export a dispute to insurance or police, your ZIP file includes a manifest with all SHA-256 hashes, so the recipient can cryptographically verify that your clips are authentic. No dedicated hardware dashcam needed. Your phone becomes the evidence source.
How Hawk Turns Your Phone into Court-Ready Evidence
Hawk records continuously while you drive, with optical-flow stabilisation to keep footage clear even on rough roads. GPS speed and timestamp overlays appear on every frame, automatically synced to your location. When a dispute happens (accident, hit-and-run, insurance claim), you tap 'Export' and Hawk packages your clips into a signed ZIP file with SHA-256 manifest, ready to send to your insurer or police. The Evidence Locker holds your most important clips behind biometric lock, so accidental deletion or device tampering cannot destroy your proof. As of June 2026, Hawk runs on iOS and Android without requiring a subscription to start recording.
Who Uses SHA-256 Dashcam Recording?
Daily commuters, rideshare drivers (Uber, Lyft, Bolt), new drivers, and anyone who wants proof of what happened on the road without buying a separate hardware device. Rideshare drivers especially benefit from Hawk's Rideshare Pro tier, which adds cabin camera recording and shift mode to record multiple trips in one session with passenger recording notices. Insurance companies and small-claims courts accept SHA-256-verified clips as evidence because the cryptographic hash proves authenticity. Police use NDSP-integrated reports (iOS) to file complaints faster.
Hawk Pricing and Free Trial
Hawk is free to start. The free tier includes 10 clips per month with 7-day retention, so you can test the app and see how SHA-256 hashing works. Local Pro costs £3.99 per month, £39.99 per year, or £49.99 lifetime. Pro adds unlimited clips, iCloud sync for locked clips, Siri Shortcuts, and voice-save commands. Rideshare Pro is £8.99 per month or £69.99 per year, and includes cabin camera, shift mode for multi-trip sessions, and passenger recording notices. No subscription is enforced to use the core recording and hashing features.
How to Export SHA-256 Evidence for Insurance or Police
Open Hawk, select the clips you want to export, and tap 'Dispute Export'. Hawk creates a ZIP file containing your video clips, a SHA-256 manifest file, and your trip map. Send this ZIP to your insurance adjuster or police department. They can verify the SHA-256 hashes using any standard cryptography tool to confirm that the footage has not been edited or corrupted. The manifest lists every clip's hash, timestamp, GPS coordinates, and speed, so there is no ambiguity about when and where the incident occurred. This approach keeps you in control of your evidence; Hawk does not auto-upload your footage to external servers.
Hawk vs. Hardware Dashcams and Other Apps
Unlike hardware dashcams, Hawk requires no installation, no wiring, no power management, and costs far less. Unlike generic phone camera apps, Hawk writes SHA-256 integrity hashes to every clip and packages them with a signed manifest for export. The evidence is cryptographically verifiable, so courts and insurers treat it as legally sound. Hawk also includes GPS overlay, trip map replay, biometric-locked evidence locker, and one-tap dispute export. For rideshare drivers, the cabin camera and shift mode features are unique to the Rideshare Pro tier, making Hawk purpose-built for commercial drivers who need multi-trip proof.

Frequently asked questions
Is SHA-256 evidence accepted by courts and insurance companies?
Yes. SHA-256 is a widely recognised cryptographic standard. When you export a Hawk dispute ZIP with a SHA-256 manifest, the recipient can verify that your clips have not been tampered with. Insurance companies and small-claims courts accept this as authentic evidence.
Can I use Hawk on my Android phone?
Yes. Hawk runs on both iOS and Android. SHA-256 hashing and evidence export work identically on both platforms.
Does Hawk upload my videos to the cloud automatically?
No. Hawk only syncs locked Pro clips to your own iCloud account if you choose to enable it. Your footage stays on your device by default. You are in control of when and what you export.
What happens if I lose my phone? Is my evidence lost?
If you are a Pro subscriber, your locked clips are synced to your iCloud account, so you can recover them. Free users should manually export important clips as ZIPs to ensure they are backed up.
Can I use Hawk as a rideshare driver?
Yes. Rideshare Pro adds cabin camera, shift mode to record multiple trips, and automatic passenger recording notices for rideshare compliance. It costs £8.99 per month or £69.99 per year.
How long does Hawk keep recordings on my phone?
Free users get 7-day retention. Pro users get unlimited retention on locked clips synced to iCloud. You can also export clips as ZIPs at any time to back them up externally.
