Website terms
Last updated 26 Oct 2026
These terms cover your use of arcturussdr.com and the services on it: accounts, downloads, the help pages, the issue tracker, the beta programme, crash reporting and remote support. They are between you and HamTEK Ltd ("HamTEK", "we"; our company details are on the contact page). Buying a licence is covered by the terms of sale, and using the software by the licence agreement. By creating an account or using these services you agree to these terms.
Your account
An account is for one person. Keep your password to yourself, and tell us if you think someone else has used your account. You must be 16 or over to open one. We may suspend or close an account that is used to break these terms, to attack the site or to harass others, and we tell you why unless the law prevents it. You can delete your account from your account page at any time; the privacy notice says what happens then.
The issue tracker and comments
The tracker is for reporting problems and suggesting improvements. What you post:
- in an issue you report, is seen only by you and HamTEK staff. Staff may publish a summary of the issue to other signed-in members, in HamTEK's own words, never your words or your name. Comments on a published issue are seen by other signed-in members, without your name, except private comments between you and HamTEK;
- must be your own words or something you have the right to share, and must not include other people's personal details, licence keys, passwords, or anything unlawful, abusive or off-topic;
- may be edited for clarity, hidden or removed by staff. We may stop a member from commenting if these rules are broken.
You keep the copyright in what you write. You give HamTEK a free, perpetual, worldwide licence to keep it, to show your comments on published issues on the tracker, to describe the problem in our own words on the tracker, in release notes and in documentation, and to use it to improve the software. Files you attach stay private to you and staff unless staff publish them.
Downloads, updates and your licence
Downloading a release needs an account and, beyond your trial or licence cover, a licence; the licence agreement covers using it. The site checks your licence when you download and when the app checks for updates. Do not pass your downloads to people who hold no licence, or try to get round the licence checks.
The beta programme
Beta builds are pre-release and may have faults (licence agreement, section 3). Testers report problems through the tracker and may be asked for a remote support session, which you can refuse or end at any time. We may end the programme, or your part in it, at any time, and you may leave at any time.
Remote support sessions
A remote support session starts only when you start it from the app. It lets HamTEK staff see the app's state, settings and logs, and change settings only when you allow it; nothing can be transmitted over it, and you can end it at any time. The privacy notice explains what is recorded and who may take part.
Availability and changes
We aim to keep the site available but do not promise it: it may be down for maintenance or for reasons outside our control, and we may change or withdraw features. Problems with the service are shown on the status page. Nothing here affects your rights under the terms of sale and the licence agreement.
Our content
The site, the help pages, the images and the ArcturusSDR name and logo belong to HamTEK or its licensors. You may read, print and quote the help pages for your own use and to help other users, with a credit to ArcturusSDR. You may not copy the site or its content for other purposes without our permission. Third-party software is credited in the third-party notices.
Links to other sites
The site links to other sites, such as the community forum, which we do not control; their own terms apply there.
Our responsibility
Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud, or for anything else that the law does not let us limit or exclude. The site and its free services (the help pages, the tracker, the beta programme and remote support) are provided free of charge, and so far as the law allows we are not liable for loss arising from using them or from being unable to use them. Your rights in relation to software you have paid for are in the licence agreement and the terms of sale.
Changes to these terms
We may change these terms. The date at the top shows when they last changed, and we email account holders about changes that affect them before they take effect.
Law
These terms are governed by the law of England and Wales, and disputes can be brought in the courts of England and Wales. If you are a consumer living in Scotland or Northern Ireland, you may also bring proceedings there. If you are a consumer living outside the UK, you keep the protection of any law in your country that cannot be excluded by agreement, and you may bring proceedings in your own courts.
