Corelog is a fully client-side application. Here is exactly what happens with your data.
Your data is never transmitted
Section titled “Your data is never transmitted”No part of your file — and nothing derived from it — is ever sent anywhere. There is no server, no API and no analytics platform to send it to. The only requests this tool makes are for its own static assets from this same domain: the analysis engine, the world map, and the offline IP-to-country database. They are downloads, never uploads. Verify it in browser DevTools → Network tab: every request is to this domain, and none carries a request body.
Geolocation without lookups
Section titled “Geolocation without lookups”IP addresses are resolved to countries against a database bundled with the application and searched inside this tab. No address is ever sent to a geolocation service. The data is DB-IP IP to Country Lite, used under CC-BY-4.0 — IP Geolocation by DB-IP (db-ip.com).
No persistent storage
Section titled “No persistent storage”Your CSV data is never written to localStorage, sessionStorage, IndexedDB, or any browser storage mechanism. When you close the tab, the data is gone.
No telemetry
Section titled “No telemetry”There is no analytics, error tracking, session recording, or fingerprinting. This tool has no interest in how you use it.
