If you contribute to, fork, or redistribute the project as open source in compliance with GPLv3, no separate commercial license is required.

Commercial licensing

TypeWhisper is offered under a dual-licensing model:

• Open-source usage is licensed under GPL-3.0-or-later.
• Commercial/proprietary usage requires a separate commercial license from the copyright holder.

You need a commercial license to use TypeWhisper in a proprietary product, a closed-source distribution, or any use case that is not compliant with GPLv3 obligations. License inquiries go to licensing@typewhisper.com. See the repository's LICENSE-COMMERCIAL.md for the full statement.

Trademark policy

The source code is GPLv3, but trademark rights are not granted under the open-source license. "TypeWhisper", the TypeWhisper name, and associated logos/app icons are trademarks of the TypeWhisper project owner.

Allowed:

• Truthful references such as "based on TypeWhisper" or "fork of TypeWhisper".
• Nominative use to describe compatibility or origin.

Not allowed without prior written permission:

• Using "TypeWhisper" as the name of a fork, distribution, product, or company.
• Using the TypeWhisper logo or app icon in a way that suggests endorsement or official status.
• Any branding that is confusingly similar to TypeWhisper.

You may fork and modify the code under GPLv3 terms, but you must rename your fork and remove TypeWhisper trademarks (name, logo, app icon) unless you have explicit written permission. Trademark inquiries go to licensing@typewhisper.com. See TRADEMARK.md for the full policy.

Attribution & copyright

TypeWhisper for Linux is © 2026 Excel on the Web, and it incorporates code from the upstream TypeWhisper project (which provides the macOS and Windows versions), © 2026 TypeWhisper. Both products are licensed under GPL-3.0-or-later.

The Linux edition began as, and remains, a derivative work that incorporates upstream code; it has diverged into an independently maintained branch with its own Linux-specific functionality while continuing to incorporate upstream changes where they apply. Copyright in the Linux product — the port, the Linux-specific additions, and the work as assembled — is held by Excel on the Web, while copyright in the underlying upstream code remains with TypeWhisper. Both notices are retained as required by the GPL. See the repository's NOTICE file for the full attribution and the list of Linux-specific additions. Modifications to upstream source files are tracked in the repository's Git history.
