ce.gg Attributions
Effective date: [PENDING LAUNCH — to be finalized after lawyer review at S11+] Last updated: 2026-06-07 (draft) Version: v0.1 (draft; legal review pending)
⚠ This is a DRAFT document. Ships with the S07 dashboard slice as architectural commitment. Final wording requires counsel review before public launch (S11+).
ce.gg is built with open-source software and open data. The notices below are reproduced to satisfy the attribution requirements of the licenses under which we use them. Each entry names the component, links to the upstream source, and reproduces the copyright/license notice verbatim from the upstream package.
If you believe an attribution is missing or incorrect, please write to legal@ce.gg.
IP-to-country fallback data — @ip-location-db/geo-whois-asn-country-mmdb
The apps/worker click-events pipeline includes a fallback geolocation lookup that resolves country codes for clicks where Cloudflare's cf-ipcountry header is blank. The underlying dataset is Number Resource Organization (NRO) statistics data, distributed via the @ip-location-db/geo-whois-asn-country-mmdb package and licensed under the Creative Commons Attribution 4.0 International License.
- Attribution: IP-to-country fallback data: licensed under the Creative Commons Attribution 4.0 International License (CC BY 4.0). © Number Resource Organization (NRO), <https://www.nro.net/>. Distributed via [@ip-location-db/geo-whois-asn-country-mmdb](https://github.com/sapics/ip-location-db).
- License: <https://creativecommons.org/licenses/by/4.0/>
- Indication of changes: None — ce.gg reads the dataset at runtime to resolve country codes; ce.gg does not modify or redistribute the dataset.
Map boundaries — Natural Earth, via world-atlas
The world map shown on the per-link Geography tab uses country boundary data from [Natural Earth](https://www.naturalearthdata.com/), redistributed as TopoJSON by the [world-atlas](https://github.com/topojson/world-atlas) package. Natural Earth's vector map data is dedicated to the public domain by its authors and contributors; no attribution is legally required, and this courtesy credit is included as a matter of convention.
The world-atlas package itself is distributed under the following notice:
