Licensing and Copyright
Relevant source files
The following files were used as context for generating this wiki page:
The FOSSBilling branding repository contains various intellectual property components, including software code, font software, and visual brand assets. Each component is governed by specific licensing terms that dictate how users can view, modify, and redistribute the project materials. While the core FOSSBilling software is open source, the brand identity—including the logo and name—carries distinct copyright protections and usage limitations.

Software and Script Licensing
The automation scripts, configuration files, and build tools within this repository operate under the broader project's open-source framework. FOSSBilling itself is licensed under the Apache 2.0 license, allowing for free use and modification of the software.
Project Dependencies
The project utilizes several third-party libraries for asset generation, each with its own licensing profile:
- Sharp: Used for high-performance image processing and conversion.
- SVGO: Used for SVG optimization and cleanup.
- TypeScript: Provides static typing for the automation scripts.

Font Licensing (SIL Open Font License)
The typography used in the FOSSBilling wordmark is based on the Manrope font. This font software is distributed under the SIL Open Font License (OFL), version 1.1.
OFL Permissions and Restrictions
The OFL provides a free and open framework for font usage while maintaining the following conditions:
- Usage and Redistribution: You may use, study, modify, and redistribute the font software.
- Bundling: You may bundle the font with other software, provided you include the copyright notice and license.
- No Standalone Sale: You cannot sell the font software by itself.
- Derivative Naming: You cannot use "Reserved Font Names" for modified versions without explicit permission.
- License Persistence: Modified versions must remain under the SIL Open Font License.

Brand Identity and Copyright
The FOSSBilling name and logo are not covered by the Apache 2.0 software license. They remain the exclusive copyright of FOSSBilling.
Permitted Usage
Users may utilize the FOSSBilling logo under specific conditions:
- Context: Use is allowed when writing about or linking to FOSSBilling.
- Truthfulness: The usage must be truthful and not misleading.
- Integrity: The logo must be used in its original form and color.
Prohibited Actions
The project enforces strict limitations to prevent brand confusion and unauthorized commercial association:
- Naming: You cannot use "FOSSBilling" as a product title, company name, or domain name.
- Modification: You are prohibited from changing the logo's appearance, capitalization, or punctuation.
- Ownership: You cannot distribute or sell the branding as your own property.
- Endorsement: You cannot use the branding in a way that implies an official partnership or endorsement without permission.

Asset Generation Workflow
The repository includes a TypeScript-based system to generate branding assets while maintaining license-compliant outputs. The generator ensures that typography is converted to paths in final SVG exports, meaning end-users do not need the Manrope font installed to render the logo correctly.
This diagram shows how source artwork is processed into final assets while maintaining visual consistency.

Conclusion
The FOSSBilling branding ecosystem balances open-source software collaboration with strict brand protection. While the tools to generate assets are open, the visual identity itself is protected to ensure the integrity and recognition of the FOSSBilling project. Users must adhere to both the SIL Open Font License for typography and the specific brand guidelines for logo and name usage.
