Dashcam App with Tamper Proof Footage: Hawk by MRVL
Hawk by MRVL is a dashcam app that turns your iPhone or Android into a court-ready recording device with SHA-256 integrity hashes written to every clip, making footage tamper-proof for insurance claims, disputes, and legal proceedings.
How Hawk Creates Tamper Proof Footage
Hawk protects your driving footage using cryptographic hashing: every video clip receives a unique SHA-256 integrity hash written at the moment of recording. This hash acts as a tamper-proof seal. If anyone modifies the footage after recording, the hash becomes invalid, and your evidence loses its chain of custody. When you export clips for a dispute, Hawk creates a ZIP file with a SHA-256 manifest listing every clip and its original hash. This manifest is what insurance companies, police departments, and small-claims courts use to verify footage authenticity. As of June 2026, Hawk is the only mobile dashcam app that embeds cryptographic integrity into every clip by default.
Evidence Locker with Biometric Lock
Beyond tamper-proof hashing, Hawk includes an Evidence Locker: a dedicated storage space for your most important clips, secured with biometric authentication (face or fingerprint). The locker is fail-closed, meaning if your device is stolen or unlocked by someone else, locked clips remain inaccessible. For Rideshare Pro users, clips also sync to your personal iCloud account, adding cloud backup without relying on MRVL servers. This dual protection ensures your evidence survives even if your phone is compromised or lost.
One-Tap Dispute Export for Insurance and Police
When you need to file a claim or report, Hawk exports your evidence in a single tap. The app creates a ZIP containing all your selected clips, a manifest with SHA-256 hashes, GPS coordinates, speed data, and timestamps. You can send this directly to your insurance company via email, upload it to a police report platform, or present it in small-claims court. On iOS, Hawk integrates with NDSP (National Driving Safety Programme) for streamlined police-report submission. No subscription is required to export; the feature is available on all tiers.
Continuous Recording with Loop Recording
Hawk records continuously while your phone is mounted on your dashboard. The app uses loop recording, meaning when storage fills up, it overwrites the oldest clips first, so you always have recent footage. Cinematic optical-flow stabilisation smooths shaky footage caused by road bumps or wind. GPS speed and timestamp overlays are optional and can be toggled via your GDPR privacy settings. Free users retain clips for up to 7 days; Local Pro and Rideshare Pro users get extended retention and higher monthly clip limits.
Who Should Use Hawk
Hawk is built for daily commuters, rideshare drivers (Uber, Lyft, Bolt), new drivers building a safety record, and anyone who wants driving evidence without buying expensive dedicated hardware. Rideshare drivers especially benefit from the Rideshare Pro tier, which adds a cabin camera, shift mode for multi-trip sessions in one go, and a passenger recording notice to meet rideshare platform compliance. Most users start free to test the app; Local Pro (£3.99/month or £39.99/year) suits casual drivers, while Rideshare Pro (£8.99/month or £69.99/year) is optimised for professional drivers.
Getting Started Without a Subscription
Hawk's free tier gives you 10 clips per month with 7-day retention, no payment card required. You get the same SHA-256 integrity hashing and one-tap export on free as you do on paid tiers. If you record more than 10 clips a month or need longer retention and iCloud sync, upgrade to Local Pro (lifetime option available at £49.99) or Rideshare Pro. Download Hawk on iOS or Android, mount your phone on your dashboard, and start recording. Your evidence is protected from day one.

Frequently asked questions
Can footage from Hawk be edited after recording without detection?
No. Every clip receives a SHA-256 integrity hash at the moment of recording. If the clip is edited after recording, the hash becomes invalid, and any court or insurance system checking the manifest will detect tampering immediately.
Does Hawk require a subscription to create tamper-proof footage?
No. SHA-256 integrity hashing is included on the free tier. You can record, hash, and export tamper-proof clips without paying. Paid tiers add iCloud sync, extended retention, and cabin camera recording, but the core evidence protection is free.
Can I use Hawk footage as evidence in court or an insurance claim?
Yes. Hawk exports clips with a SHA-256 manifest that proves authenticity and chain of custody. Insurance companies and courts accept this format. For additional peace of mind, iOS users can submit police reports through the NDSP integration.
Does Hawk upload my footage to MRVL servers?
No. By default, clips stay on your phone. Rideshare Pro users can optionally sync locked evidence clips to their personal iCloud account for backup, but MRVL never stores your footage on its servers.
What's the difference between Local Pro and Rideshare Pro?
Local Pro (£3.99/month) is for solo commuters and casual drivers; it includes iCloud sync and longer retention. Rideshare Pro (£8.99/month) adds a cabin camera, shift mode for multi-trip sessions, and a passenger recording notice, tailored for Uber, Lyft, and Bolt drivers.
Do I need a dedicated dashcam device if I use Hawk?
No. Hawk turns your existing iPhone or Android phone into a court-ready dashcam with tamper-proof hashing. Simply mount your phone on your dashboard and record.
