Who we are
The S+ CIS Calculator is published by Sovereign Plus Solutions Ltd ("S+", "we"), company number 12223858, Unit 6, St Georges Square, Portsmouth, PO1 3EY. We are the controller for the personal data described here. Contact: info@sovereignplus.com, 023 9280 0686.
This policy covers the S+ CIS Calculator tools you use inside AI assistants such as ChatGPT and Claude, and these help pages. If you contact S+ by phone or email, we handle that under our normal business privacy practices as a CIS bureau.
What we collect
| Category | What exactly | Why |
|---|---|---|
| Calculator answers | The numbers the assistant sends to the tool when you ask it to: number of subcontractors, weekly labour spend, how many are unverified and the rate deducted, number and lateness of late returns, share of labour through agencies, whether you hold gross payment status. Optionally the number of subcontractors for a pre-filled email. | To calculate the estimate you asked for and send the result back. |
| Technical request data | IP address, time of request, browser or client type, as processed by our hosting provider when a request reaches the server. | To deliver the service and protect it from abuse and attacks. |
The tools do not ask for or need your name, company name, email, phone number, UTR, National Insurance number, bank or card details, health data, location, your chat history or any account login. There is no sign-in. Please don't type such details into a question meant for the tool.
The AI assistant you use (for example ChatGPT or Claude) decides what to send to the tool and keeps your conversation under its own privacy policy. We don't receive your conversation, only the inputs listed above.
What we do with it
- We use calculator answers only to work out and return your estimate. We don't store them, build profiles from them, sell them or use them for advertising.
- We don't use cookies or tracking on the tool's result card.
- Pre-filled emails and phone links on the result card only open your own email or phone app. Nothing reaches S+ unless you choose to send it.
Legal basis (UK GDPR): our legitimate interests in providing a free CIS information tool you have chosen to use and in keeping it secure.
Who receives it
- Our hosting and content-delivery provider, which runs the server and processes requests on our behalf.
- The AI assistant provider you use, which sends your inputs to us and receives the result.
- Authorities, if the law requires it.
Some of these providers may process data outside the UK. Where they do, they use safeguards recognised under UK data protection law.
How long we keep it
- Calculator answers: not stored. They exist only while your request is being worked out, then are discarded.
- Technical request data: held by our hosting provider only as long as needed for security and to run the service, normally no more than 30 days.
- If you email or call S+: kept as long as needed to deal with your enquiry and, if you become a client, for the periods UK tax and company law require.
Your choices and rights
- You decide whether to use the tool, and you can disconnect it from ChatGPT or Claude at any time in their settings.
- You can ask us for access to, correction of or deletion of your personal data, or object to how we use it, by emailing info@sovereignplus.com. Because the tool keeps no calculator answers, there is usually nothing about your questions to return.
- You can complain to the Information Commissioner's Office: ico.org.uk/make-a-complaint.
Children
The tool is for businesses and is not aimed at anyone under 18.
