Terms
Plain English terms of use.
The license
Purr is released under the MIT License. That file is the legally binding text. Everything below is a plain English summary of what it means.
What you can do
Anything you want. Use Purr for personal projects, at work, in a commercial product. Copy it, change it, fork it, redistribute it. Sell a modified version if you want to.
What you have to do
Keep the original copyright notice and the MIT licence text in any copy you redistribute. That is the only condition.
What we promise
Nothing. Purr is provided as-is, with no warranty, express or implied. We will try to fix bugs and keep the app working on new macOS versions, but we make no guarantees. If the app breaks something, you cannot hold us liable.
How you use it is on you
The app records audio when you hold the hotkey. Recording other people without their knowledge or consent may be illegal in your jurisdiction. Some places require all-party consent. Some only require one. It is your responsibility to know your local law and to comply with it.
The same applies to anything Purr transcribes for you. If you paste a transcript that contains someone else’s confidential information somewhere they would not expect, that is on you, not on the app.
Third-party models
Purr downloads speech recognition models from Hugging Face on first use. Those models carry their own licences:
- Parakeet TDT v3 (NVIDIA / FluidAudio): CC-BY-4.0
- Whisper (OpenAI / WhisperKit): MIT
- Gemma 3 4B (Google), used for the optional summarizer: Gemma Terms of Use
Downloading those models means you agree to their terms.
Changes
These terms can change. The date at the top reflects the current version; the full history is in the git log of this file. Continuing to use the app after a change means you accept the new terms.
