📄 License
Everything in this repository is licensed under the Apache License, Version 2.0, with one exception: cloudpdf/server — the self-hostable CloudPDF server — is Fair Source, under the Fair Core License, FCL-1.0-ALv2. Its source may be inspected, copied, and modified for purposes permitted by the FCL. That does not make the server free to run: while a release remains under the FCL, running or self-hosting it requires a valid CloudPDF license (a license key for a connected deployment or a signed certificate for an air-gapped deployment). You may not move, change, disable, or circumvent the license-key functionality; enable protected functionality without a valid license; or remove protected functionality. Competing Uses, as defined in the FCL, are also prohibited. Each release automatically becomes Apache-2.0 two years after publication. See LICENSING.md for the full licensing map, including website content.
