Privacy Notes

Publicly stated data-handling notes that matter when evaluating Open Knowledge Maps.

Access logs are retained for 30 days, error logs for 90 days, and security logs for 180 days.

The FAQ says live maps are built from external data providers and the site uses encrypted connections.

Product Snapshot

Open Knowledge Maps is a nonprofit, open-source discovery platform that turns scholarly search into a visual map. It is built for topic exploration, not for managing an entire research workflow.

What You Can Do With It

Why It Stands Out

It makes the structure of a research topic visible instead of presenting only a flat result list, and the service is run as an open, community-funded infrastructure rather than a conventional commercial SaaS.
