The source code of LabFox is released under the Apache License 2.0 (LICENSE). However, the name and the brand are not included in that license.

You may do the following without separate permission.
- Use of the source code — use, modification, redistribution, and commercial use under the Apache-2.0 terms
- Nominative use — mentioning the name in order to state a fact, such as "uses LabFox", "based on LabFox", or "contributed to LabFox"

- Unmodified redistribution — passing on official release binaries exactly as they are, without changes
- Covering LabFox in technical documentation, blogs, reviews, and courses
- Listing in package repositories — distributing an unmodified build, provided the origin is identified as this project

This project is a fork of LabFox (https://github.com/theorvane/labfox), licensed under Apache-2.0. It is not affiliated with or endorsed by the LabFox project.

The code is kept open, but there must be only one app named "LabFox" distributed through the stores so that users can trust what they are installing. The trademark is reserved not in order to restrict use of the code, but to prevent the confusion of different apps circulating under the same name.
Signal, Element, and Firefox use the same approach.

- "GitLab" is a trademark of GitLab Inc.
- "GitHub" is a trademark of GitHub, Inc.
LabFox uses these names solely to describe interoperability, and does not use GitHub's logos, icons, illustrations, UI assets, or brand elements.
