Data sources & compliance
Every signal on Slicegraph originates from an official public register or public infrastructure directory. We do not scrape social networks, buy contact databases, or process data behind logins. Each signal links back to its source document.
Officiële bekendmakingen (KOOP)
Dutch government gazettes: permit applications and grants published by municipalities, provinces and water authorities.

TenderNed
Dutch public procurement: tender publications and awards, contracting authorities and closing dates.
Open public procurement data mandated by the Aanbestedingswet.

GDPR posture
Slicegraph processes company-level information: organization names, registration numbers (KvK), locations and public events concerning those organizations. Our legal basis is legitimate interest in processing lawfully published business register data.
Sole proprietorships registered in business registers may carry a personal name as their trade name; we process these solely in their capacity as registered businesses. We do not enrich signals with personal contact details, and permit signals are intentionally not attributed to natural persons.
