Who we are
The S+ Money CIS Refund Calculator is published by Sovereign Plus Money Ltd (company registration in progress) ("S+ Money", "we"). We are the controller for the personal data described here. Contact: hello@splusmoney.co.uk.
This policy covers the calculator tools you use inside AI assistants such as ChatGPT, the web calculator at refund.splusmoney.co.uk, and these help pages.
What we collect
| Category | What exactly | Why |
|---|---|---|
| Calculator figures | The numbers you or your AI assistant enter: tax year, region, gross CIS income, CIS deducted or rate, materials and expenses, business miles, other income and tax paid on it. | To calculate the estimate you asked for and return it. |
| "Let us file it for you" form (web calculator only, if you choose to fill it in) | Your name, mobile number, optional email, and the tax year and estimate shown on screen. Your consent tick. | To contact you about preparing and filing your tax return, which you asked for (legal basis: steps at your request before a contract, and your consent for the contact). |
| Technical request data | IP address, time of request and browser or client type, processed by our hosting provider when a request reaches the server. | To deliver the service and protect it from abuse. |
The calculator does not ask for or need your name, UTR, National Insurance number, bank or card details, health data, location, chat history or any login. There is no sign-in.
The AI assistant you use decides what to send to the tool and keeps your conversation under its own privacy policy. We don't receive your conversation, only the figures listed above.
What we do with it
- Calculator figures are not stored. In ChatGPT they're worked out on our server and discarded once the answer is sent. On the web page the sums run in your own browser and the figures never leave your device unless you send the form.
- The "Let us file it for you" form is used only to contact you about filing your return. We don't sell it or use it for advertising, and you can ask us to delete it at any time.
- No advertising cookies or tracking on the result card or the calculator page.
Legal basis (UK GDPR): our legitimate interests in providing a calculator you've chosen to use and keeping it secure; for the form, steps you asked us to take before a contract, and your consent to be contacted.
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 figures to us and receives the result.
- If you send the form: the people at S+ Money who prepare returns, and the customer-records service we use to store enquiries.
- Authorities, if the law requires it.
Some 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 figures: not kept.
- Form enquiries: up to 12 months if you don't become a client; if you do, for the periods UK tax law requires.
- Technical request data: normally no more than 30 days, kept by our hosting provider for security.
Your rights
- You can disconnect the app from ChatGPT at any time in its settings.
- You can ask for access to, correction or deletion of your personal data, or object to how we use it, by emailing hello@splusmoney.co.uk. You can withdraw consent to be contacted at any time.
- You can complain to the Information Commissioner's Office: ico.org.uk/make-a-complaint.
Children
The calculator is for self-employed adults and is not aimed at anyone under 18.
