The short version. We collect only what the tools need to work: your profile if you make one, the analyses you choose to save, requests you send us, and the questions the AI answers for you. We never sell your information or use it for advertising. You can ask us to see or delete it at any time.
BBC – Big Brain Consulting is a free online toolkit of business tools, run by BBC – Big Brain Consulting. For anything about your data, email [email protected].
| What | Why | How long we keep it |
|---|---|---|
| Your account: email and password | So you can log in from any device and keep your work. Passwords are never stored as you type them: we keep only a scrambled version that can't be turned back into your password. | Until you ask us to delete your account, or 2 years after you last use the site. |
| Your profile: name, email, role, what you work on, and whether you want updates | So you can save and export your work, and, only if you tick the box, so we can tell you about new tools. | Until you ask us to delete it, or 2 years after you last use the site. |
| Analyses you save | So you can come back to them. | Until you delete them or ask us to, or 2 years after you last use the site. |
| "Hire a team" requests: name, email, company, your question, and any simulation you attach | So we can match you with a team and reply to you. | Up to 2 years, or until you ask us to delete it. |
| Questions sent to the AI, including the numbers from your analysis, and the AI's answers | To give you an answer, keep the service working fairly (daily limits) and improve the tools. | 12 months. |
| Documents you upload to the M&A Due Diligence Analyst, and the companies you research with it | Uploaded files are sent to Google's Gemini so it can read the figures. We don't keep the files themselves: only the figures and notes read from them, with the file name and page numbers, and only as part of an analysis you save. Company research is carried out by Gemini using Google Search. | Files: not kept. Research requests: 12 months. Saved analyses: as above. |
| Simple activity, such as which tool was opened | To understand which tools are useful. | 13 months. |
| Visitor statistics | To count visits, pages and countries. This uses Cloudflare Web Analytics, which does not use cookies and does not build a profile of you. | Kept by Cloudflare in summary form. |
| Settings kept in your own browser, such as an unfinished draft or chart view | So the site remembers your place. These stay on your device and you can clear them in your browser. | Until you clear them. |
Please don't upload documents you don't have the right to share, or that contain other people's personal information.
When you log in, we set one small cookie that keeps you logged in for up to 60 days. It is strictly necessary for your account to work, isn't used for tracking or advertising, and is deleted when you log out.
We use your information because it is needed to provide the tools you choose to use, or because we have a legitimate interest in running and improving the site. Update emails are sent only if you ask for them, and you can stop them at any time.
These companies may process data outside the UK. Where they do, they use the legal safeguards UK data protection law requires.
You can ask to see the information we hold about you, correct it, delete it, or object to how we use it. Email [email protected] from the address you used and we will reply within one month. If you are unhappy with how we handle your data, you can complain to the Information Commissioner's Office (ICO) at ico.org.uk.
The tools are designed for businesses and adults. They are not intended for children under 18.
The tools give estimates to help you think through decisions. They are not financial, legal or professional advice. AI-generated values are estimates to check, never facts.
If we change how we use your information, we will update this page and the date at the top.
