Privacy

Keycloak Community Extension Registry (KCER) is a community index of public open-source Keycloak extensions. This page explains the personal data we process — both for visitors and for the maintainers whose public projects we index — why, and how to exercise your rights.

Visitors

KCER sets no tracking cookies and uses no third-party analytics or advertising. We don't collect personal data from visitors beyond the transient request logs our hosting provider keeps for security and reliability.

Maintainers & projects we index

KCER catalogs public repositories. For each, we read and store public information from the GitHub API and Maven Central, including repository metadata (description, stars, license, topics, releases, artifact checksums) and the rendered README and release changelogs. Where a repository is owned by an individual, we also store public profile fields: GitHub login, display name, avatar, bio, and website link.

This information is obtained from GitHub's and Maven Central's public APIs — not collected from you directly — and is shown with attribution and a link back to the original source.

Why we process it (legal basis)

We process this public information under our legitimate interest (GDPR Art. 6(1)(f)) in providing a useful, discoverable index of community Keycloak extensions. We use it only to present the catalog. We do not profile individuals, send marketing, sell or share the data with third parties, or use it for surveillance.

Retention

An entry is kept while its upstream repository remains public and is refreshed by a nightly job. If a repository disappears, the entry is archived and removed from listings. We also remove entries on request (below).

Your choices & rights

Entries are listed as unclaimed until a maintainer claims them (self-service claiming is planned for a later phase). To correct information or have your project removed, email us and we'll action it.

If you are in the EU/UK, you also have the right to access, rectify, erase, or object to our processing of your personal data; contact us to exercise these rights.
