Privacy
What this site collects, who processes it, and what you can ask me to do about it. Last updated 19 August 2026.
Who is responsible
Numen is the data controller for this website. Numen is run by Raj Dhillon and operates in the United Kingdom. For anything on this page, including any request set out below, the contact is raj@numenai.co.uk.
What this site collects
Two things collect data on this site, and nothing else does. There is no contact form, no newsletter sign-up, no chat widget and no advertising network on any page.
1. Analytics, on every page
This site can use Google Analytics 4 (property G-ZL8F4WYKY4) to count visits and see which pages get read. It runs only if you accept it in the banner shown on your first visit. Until you accept, the Google Analytics tag is not loaded at all: no request is made to Google and no cookie is set. If you accept, Google sets cookies in your browser and receives your IP address, the pages you view, the approximate location those suggest, and basic device and browser information. Google Analytics is configured to record this on https://numenai.co.uk only.
Google Ireland Limited and Google LLC act as processors for this, and the data may be transferred outside the UK under the UK extension to the EU-US Data Privacy Framework. Google's own notice is at policies.google.com/privacy.
2. The booking calendar, on the sourcing review page
The sourcing review page embeds a booking calendar provided by Cal.com, served from its European instance at cal.eu. It loads only on that page. If you book, you give Cal.com your name, your email address, the time you picked and anything you type into the booking form, and a video meeting link is created for the call. Cal.com acts as a processor for that booking.
A record of the booking is also kept in Numen's own customer records, so that the call can be prepared for and followed up.
Why, and on what legal basis
- Analytics — to understand how the site is used and improve it. Legal basis: consent, given in the banner and withdrawable at any time in the cookies section below.
- Bookings — to hold the call you asked for and to contact you about it. Legal basis: taking steps at your request before entering a contract.
- Email you send me — to reply to you. Legal basis: legitimate interests, in answering someone who has got in touch.
How long it is kept
- Analytics data: retained by Google for 14 months, then deleted automatically.
- Booking and enquiry records: kept for as long as we are talking, and for two years after the last contact, unless you ask for them sooner.
Who else sees it
Google and Cal.com, in the roles described above, and the hosting and email providers that run this site and my inbox. Nobody else. Your details are not sold, rented, or passed to anyone for their own marketing.
Your rights
Under UK GDPR you can ask me for a copy of the personal data I hold about you, ask me to correct it, ask me to delete it, ask me to restrict or stop using it, and object to my using it. You can also ask for it in a portable format. There is no charge, and I will reply within one month.
Ask by emailing raj@numenai.co.uk. If you are not happy with how I have handled it, you can complain to the Information Commissioner's Office at ico.org.uk.
Cookies, and how to change your mind
On your first visit this site asks whether Google Analytics may run. Nothing analytics-related happens before you answer: the Google tag is not loaded, no request goes to Google, and no cookie is set. Accepting loads the tag and lets it set its cookies. Refusing loads nothing, and if you had accepted before, refusing also deletes the analytics cookies already in your browser.
Your answer is kept in your browser's local storage under the key numen-analytics-consent, not in a cookie, so that refusing cookies does not require setting one. It stays on this device only and is never sent to me or to Google. Clearing your browser storage clears it, and you will be asked again.
Advertising is switched off permanently. Google Consent Mode is set on this site with advertising storage, advertising user data and advertising personalisation all denied, and accepting the banner raises analytics storage only.
The booking calendar on the sourcing review page sets its own cookies to work, and those are not covered by the banner. You can block or delete every cookie in your browser settings. Nothing on this site stops working if you do, apart from the booking calendar.
Changes
If what this site collects changes, this page changes with it, and the date at the top changes too.
