GPL-3.0 summary for operators#

Permitted: private runs without distribution, personal modifications, commercial use of the software itself. Required when you convey the program: provide corresponding source or a written offer, include license and copyright notices, document changes in modified files, and license derivatives under GPL-3.0. Read the full LICENSE text.

Redistribution checklist#

  1. Source offer matching the binary (or exact tag link). 2. Include LICENSE and preserve notices. 3. Aggregate third-party licenses from third-party/ into NOTICE where required. 4. Do not imply LizardByte, NVIDIA, or Moonlight endorsement. 5. Label forks clearly. 6. Assess H.264/HEVC distribution rules in target regions. Verify SHA256SUMS on repackaged release artifacts.

Privacy and data handling#

Self-hosted: no mandatory cloud telemetry in the streaming path. Pairing certs and config stay on the host (~/.config/sunshine/). Optional webhook_url_* sends events you configure to third-party URLs. API tokens are stored hashed; protect sunshine.conf permissions. Operators own GDPR, logging, and LAN exposure of the HTTPS Web UI (default 47990). Report vulnerabilities privately via GitHub Security Advisories.
