What SIGNAL does
SIGNAL is an intelligence briefing platform that monitors publicly available expert commentary from think tanks, defense analysts, OSINT researchers, and government publications. We use AI to summarize articles and synthesize daily briefings.
Information we collect
From subscribers: Email address (for account creation and briefing delivery). We collect the minimum information necessary to provide the service.
From monitored sources: Publicly available articles, names, and professional affiliations of public figures who publish expert commentary through public channels (RSS feeds, government APIs, open protocols).
Lawful basis for processing
We process subscriber data based on consent (you sign up and can unsubscribe anytime). We process public expert commentary based on legitimate interests under GDPR Article 6(1)(f) — providing aggregated analysis of publicly available professional commentary on matters of public concern. A full Legitimate Interest Assessment is available on request.
Data retention
Raw article text is automatically deleted after 7 days. AI-generated summaries and vector embeddings are retained indefinitely as our original analytical work. Source metadata (URLs, timestamps, provenance) is retained for compliance audit trails. Subscriber data is retained while your account is active and deleted within 30 days of a deletion request.
AI-generated content
SIGNAL uses AI (Claude by Anthropic) to summarize articles and generate briefings. All AI-generated content is reviewed by a human editor before publication and is labeled as “AI-assisted analysis.” Machine-readable metadata is included per EU AI Act Article 50 requirements.
