PulseSDR is freeware for personal, non-commercial use. It is closed-source software; it is licensed to you, not sold, and its source code is not published. By installing or using PulseSDR you accept this licence. If you do not accept it, do not install or use the software.
1. What you may do
- Install and use PulseSDR on any number of your own computers, free of charge, for your personal, non-commercial use (for example as a radio hobby, for learning or for your own research).
- Download PulseSDR, and its updates, only from the official website pulsesdr.cc or the official PulseSDR listing in an app store (such as Google Play). To share PulseSDR, send people that link.
2. What you may not do
- Use PulseSDR commercially: in or for a business, for paid work or services, for monitoring done for others, or to make money in any other way, without written permission from PulseSDR ([email protected]).
- Copy PulseSDR for others, or upload, mirror, re-host or otherwise distribute it (installer, portable package or program files), free or paid, anywhere other than the official sources above.
- Sell, rent or lease PulseSDR, or bundle it with any product.
- Modify, translate, decompile, disassemble or reverse engineer PulseSDR, or try to obtain its source code, except where applicable law expressly permits this despite this restriction.
- Remove or change copyright notices, the licence, or the protection of recordings (encryption, device binding, watermark), or help others to do so.
- Distribute modified copies, or use PulseSDR's name, icon or artwork for another product.
3. Third-party components
PulseSDR includes third-party components that remain under their own licences (listed in THIRD-PARTY-NOTICES and on the About page). Nothing in this licence limits your rights under those licences. In particular, the FFmpeg libraries in the “codecs” folder are licensed under the GNU Lesser General Public License v2.1 or later: you may replace them with your own build of FFmpeg, and reverse engineering for the purpose of debugging such replacements is permitted.
4. Using radio lawfully
Receiving, recording, decoding, transcribing or sharing radio transmissions is regulated differently in each country. Some transmissions (for example pagers, private or encrypted services) may not be intercepted, recorded, disclosed or used. You alone are responsible for using PulseSDR in line with the laws that apply to you. PulseSDR shows notices before recording, transcription and pager decoding; accepting them does not make an unlawful use lawful.
5. Recordings and AI output
Audio recordings are stored in PulseSDR's protected format and can only be played in PulseSDR on the computer that made them; they carry a device identifier and an inaudible watermark. Transcriptions and translations are produced by AI models on your computer and may be wrong or incomplete; do not rely on them for safety, legal or other important decisions without checking the original audio.
6. No warranty
PulseSDR is provided “as is”, without warranty of any kind, express or implied, including fitness for a particular purpose, accuracy of decoded or translated content, and non-infringement.
7. Limitation of liability
To the extent permitted by law, PulseSDR and its authors are not liable for any damages arising from the use of, or inability to use, the software, including loss of data, recordings or hardware damage. Nothing in this licence excludes liability that cannot be excluded by law.
8. Updates and ending this licence
PulseSDR may offer updates, which are covered by this licence unless they come with a new one. Future versions may come with different terms. This licence ends automatically if you break it; you must then stop using PulseSDR and delete your copies.
9. Governing law
This licence is governed by the law of the Republic of Poland, without prejudice to mandatory consumer protection rights in your country of residence.
