Court Admissible Dashcam App for UK Drivers: Hawk
Hawk by MRVL is a phone dashcam app that records driving footage with SHA-256 integrity hashes on every clip, creating evidence-grade records you can submit to courts, police, or insurers. It works on iOS and Android with no subscription needed to start recording.
What Makes Hawk Court-Ready in the UK
Hawk creates legally defensible driving evidence by writing a cryptographic SHA-256 hash to every video clip. This integrity hash proves the video hasn't been edited or tampered with after recording, which is the standard legal requirement for evidence admissibility. When you export a dispute, Hawk bundles the video, hash, GPS data, and a signed manifest into a single ZIP file. You can send this directly to your insurer, the police, or submit it in small-claims court. The hash and manifest together establish a complete chain of custody for your footage. As of 2026, Hawk is used by UK commuters, new drivers, and rideshare drivers who need evidence without buying a separate dashcam device.
Evidence Locker and Biometric Security
Hawk's Evidence Locker is a biometric-locked vault that stores your most important clips separately from regular recordings. Once a clip is locked with your fingerprint or face ID, it cannot be deleted or altered, even if your phone is stolen or lost. This fail-closed design means the clip remains protected until you deliberately unlock and export it. For rideshare drivers and commuters handling sensitive incidents, the locker prevents accidental deletion and gives you a secure backup trail. You can lock multiple clips from different journeys and export them together with their combined hashes for multi-incident disputes.
GPS, Timestamps, and Trip Replay
Every recording includes GPS speed and timestamp overlays that appear directly on the video. These overlays are encrypted during recording and stored as part of the manifest, so they cannot be faked or removed. Hawk's trip map replay shows a MapKit polyline of your exact route during the evidence clip, useful for reconstructing the incident for police reports or insurance claims. You control whether GPS data is captured via your GDPR privacy profile settings. This location and speed data, combined with the video hash, creates a complete spatial and temporal record of the event.
One-Tap Dispute Export for Courts and Police
When you need to submit evidence, Hawk exports a dispute ZIP containing the video file, the SHA-256 hash certificate, GPS data, timestamps, and a signed manifest. You can then email or upload this ZIP to your insurer, send it to the police via the NDSP police-report submission tool (iOS), or hand it to a solicitor for small-claims court. No need to download clips individually or manually sign documents. Hawk handles the cryptographic proof. Rideshare drivers can export multiple shifts or cabins in a single batch for pattern-based disputes.
Free vs. Paid Tiers
Hawk's free tier records continuously but stores only 10 clips per month with 7-day retention. That's enough for one or two incidents. Local Pro costs £3.99 per month, £39.99 per year, or £49.99 lifetime, and adds unlimited recording, permanent iCloud sync for locked clips, and voice-save shortcuts. Rideshare Pro costs £8.99 per month or £69.99 per year and includes cabin camera recording, shift mode for tracking multiple trips in one session, and passenger recording notices (required by UK law in some regions). Start free, upgrade if you're a daily commuter or rideshare driver.
Legal Considerations in the UK
Hawk itself is legal to use as a dashcam in the UK. Recording inside your own vehicle is permitted. However, if you're recording a passenger in a rideshare or taxi, UK law requires you to notify them. Hawk's Rideshare Pro tier includes on-screen passenger recording notices to meet this requirement. Recording on public roads is legal in the UK provided your dashcam doesn't obscure your view, and Hawk's small windscreen mount design does not block sightlines. Always check your insurance policy, as some insurers offer discounts for dashcam evidence while others have specific requirements. The integrity hash and manifest that Hawk exports are designed to meet evidence standards in civil and small-claims cases; criminal courts may have additional procedural requirements.

Frequently asked questions
Can I submit Hawk footage as evidence in a UK court?
Yes. Hawk's SHA-256 integrity hash and manifest prove the video hasn't been tampered with, meeting the standard for video evidence in civil and small-claims courts. Export the dispute ZIP and provide it to your solicitor or the court. Criminal courts may have additional procedural rules, so check with your legal representative first.
Is Hawk legal to use as a dashcam in the UK?
Yes, dashcams are legal in the UK. Hawk doesn't obscure your view and records on public roads without restriction. If you're using Rideshare Pro to record passengers, you must notify them on screen, which Hawk does automatically.
Does Hawk upload my videos to MRVL servers?
No. Hawk stores footage locally on your phone. Pro tier syncs locked evidence clips to your own iCloud account for backup, but MRVL never stores your raw video.
How long does Hawk store recordings?
Free tier: 7 days, maximum 10 clips per month. Pro tier: unlimited retention on your phone plus iCloud backup for locked clips. Recordings loop over older files when your phone's storage fills.
What's the difference between Local Pro and Rideshare Pro?
Local Pro is for personal commuting, with unlimited recording and iCloud backup. Rideshare Pro adds cabin camera, shift mode for multi-trip sessions, and required passenger recording notices for professional drivers.
Can I use Hawk if I have an Android phone?
Yes, Hawk works on both iOS and Android. All core features including integrity hashing, evidence export, and biometric locker are available on Android. Police-report submission via NDSP is iOS only.
