And beyond these: LOCUS is built for anyone, professional or private, who needs to document a fact verifiably and with a certain date.

By domain

When a moment does not repeat

Every situation where you must later prove authenticity, date and place — without the other party being able to claim the material was fabricated or altered afterwards.

No. 01

Mobility and accidents

Road accidents: position of vehicles, damage, road signs, plates and the other party's documents before removal; bicycle or scooter incidents; support for the accident report.

No. 02

Property and real estate

State of the premises at the start and end of a lease (to protect the deposit); damage from a neighbour's leaks or flooding; building abuse, encroachment and easements; vandalism and graffiti.

No. 03

Intellectual property and counterfeiting

Counterfeit goods on display in the street; unauthorised use of your works, photos or designs (shop windows, billboards, events); plagiarism — documented before the evidence disappears.

No. 04

Consumer and contracts

Goods delivered damaged or defective (return/warranty); condition of rented goods on return (cars, equipment); private sales.

No. 05

Environment and territory

Illegal dumping, discharges and pollution; civic reports (hazards, disrepair) with dated and geo-referenced proof.

No. 06

Neighbourhood, work and safety

Neighbour disputes and nuisances (noise, occupation of shared spaces); workplace safety conditions or injuries; damage or threats to your property.

No. 07

Authenticity in the AI era

Prove that a photo or video is original, unaltered and dated, against claims of manipulation or synthetic content (deepfakes).

No. 08

Insurance and claims

Condition of goods and property before and after a loss (theft, fire, weather events); dated inventory for reimbursement; documentation to support insurance assessments.

No. 09

Construction and inspections

Work progress (milestones) and acceptance tests with a certain date; defects and non-conformities; site safety; delivery and acceptance of supplies.

No. 10

Agriculture and crop damage

Damage from wildlife, hail or plant diseases on crops and facilities; dated, geo-referenced proof for compensation and farm insurance.

No. 11

Transport and logistics

Condition of goods at loading and unloading, integrity of seals and containers, in-transit damage to support CMR/delivery notes.

No. 12

Cultural heritage, art and restoration

Conservation state before and after treatment, authentication and provenance of works; dated documentation for assessments and insurance.

These are just examples. LOCUS applies wherever you need to fix a fact with a certain date, place and authenticity: the real range of cases is far broader than this list.

Warning. Recording people, conversations and private places is subject to legal limits (privacy/GDPR and third-party rights). LOCUS documents a fact and strengthens its authenticity, but admissibility and use remain assessed case by case.
