Who we are

Datum Forge Ltd, company number 17350432, registered office Basement Flat, 8 Saville Place, Bristol BS8 4EJ. We are the controller of the personal data described on this page. Questions and requests go to hello@datum-forge.com.

What this site collects, and why

When you send an enquiry

Your name, email address, what you tell us you would like to talk about, and, if you give them, your company, its website and your phone number. Alongside them the form records the page you sent it from, the time, a scrambled version of your internet address that cannot be turned back into the address (used only to limit abuse of the form), and your browser’s identifying string. We use this to reply to you, to set up the call if you want one, and to keep a record of the enquiry in our own customer system. Our basis is our legitimate interest in answering people who contact us, and, where a call leads to work, taking the steps you ask for before a contract. We keep an enquiry while we might work together. Nothing deletes it automatically: we delete enquiry records by hand, when you ask us to or when we review them and find they are no longer needed. If we work together, the engagement’s own terms apply.

If we want to contact you beyond replying

We may follow up on your enquiry. If we ever want to send you anything beyond that, we will ask first or rely on the rules that allow business-to-business marketing, and every such message will carry a way to stop them.

When we share a document with you

Some documents, such as an audit report, we share by a private link and a six-digit code that we send you separately. With the link we keep your name and, if we email the link to you, your email address. Each time the link is used we record when, the country and town your connection comes from (as our hosting provider reports it), and the kind of browser. We do not record your internet address. We use this to keep the document safe and to know that it reached you, which is our legitimate interest and that of the client the document is about. The document is deleted from our storage ninety days after we share it, or sooner once the issues it describes are fixed; the record of when it was opened is kept with the records of that piece of work.

Measurement of how this site is used

This site counts how its pages are used so we can improve it. By default it records which pages are opened, when (reported by the hour or the day), the website you arrived from (its name only, never the full address), your country and at most a coarse region or city, the kind of device, and the browser and operating system family. It does not record your name, your internet address, an advertising identifier, or anything that follows you to another website. A device identifier supplied by our hosting provider is used only to avoid counting one visit twice and is discarded after twenty-four hours. Individual records are deleted after forty-eight hours; what remains is a daily count that cannot be turned back into a visit. This runs under the UK rules that allow a website’s own statistics without consent, on two conditions we meet: this clear information, and a simple, free way to object. Our basis is our legitimate interest in seeing which pages are used and where something is broken. You can object at any time, free, under “Objecting” below or on the How we measure this site page, at /measurement. The choice shown on your first visit says where. Pressing Reject in that choice does not object to this counting: Reject is your answer about the measurement that needs your consent.

Detailed analytics with Umami, only if you accept it

If you press Accept in the choice shown on your first visit, or switch detailed analytics on below, the site also uses Umami, analytics software we run privately for this site, not a service that sees other websites. It records the pages you visit and in what order, the site or campaign link that brought you here (including any campaign tags in that link), your approximate location (country, region, town or city), your device, browser, operating system, screen size and language, and which links, buttons and forms you use (that a form was sent, never what you typed in it). Your internet address is used to work out your location and to group your page views into a visit, and is not stored: Umami keeps a scrambled code made from it and your browser, which changes every month. Umami sets no cookie. Nothing from Umami loads before you have chosen, and nothing from it is requested from anywhere but this site’s own address. Our basis is your consent, which you can withdraw at any time with the switch below. We keep detailed analytics for twenty-five months; anything older is deleted automatically every night. If you press Reject, Umami never loads, not even its script.

Campaign measurement, only if you accept it

Pressing Accept also turns on campaign measurement, or you can switch it on below. Once it is on, when you arrive from an advert, email or link that names its campaign, the site records which one: the source, medium and campaign names carried in the address you arrived on, and nothing else from that address. The visit on which you first answer is never recorded this way. They are kept in one small note on your device for thirty days, so that an enquiry you send in that time can be matched to them, and the individual records are kept for up to ninety days. Our basis is your consent, which you can withdraw at any time with the switch below. If you press Reject, none of this is recorded.

Accept does not turn on advertising measurement: this site runs no adverts, so it keeps no advert identifier and no scrambled contact details with an enquiry, and it sends nothing to any advertising platform.

Changing your answer

Each switch takes effect straight away, on this page and every other. Switching one off later is as easy as switching it on.

The choice shown on your first visit, again:

Objecting

The law that lets this site count visits without asking also gives you a simple, free way to object to that counting, and this is it. The counting rests on our legitimate interest, and you have the right to object to it at any time. Untick the box and your visits stop being counted, straight away and on every page. One small note is stored on your device so the site remembers, and that note is the only thing kept. It changes nothing else about how the site works.

Your choices about measurement

These are recorded as evidence that a choice was shown and made. When the choice is shown, the site records that it was shown, on which page, the version of the words, the time, and a random reference made for that page alone; showing it sets nothing on your device. When you answer, by accepting or rejecting, the site sets one cookie, consent_ref, holding that random reference (the cookie policy lists it), and records your answer against it: what you chose, and when. No name, no internet address and no advertising identifier are kept with these records; a scrambled address used only to limit abuse is removed after twenty-four hours. The records are kept for twenty-five months.

Counting at the server

Every page request is counted at our server as a path and a verdict on whether it came from a declared crawler. No identifier of any kind is kept with it.

Staff sign-in

Part of this site is a private workspace for the three founders. Signing in uses a one-time code sent by email and sets the cookies described in the cookie policy. Visitors never sign in.

Email

If you email us, your message is handled in our Microsoft 365 mailboxes.

Businesses we research

Apart from this website, our own system finds businesses we might work with and watches public pages that matter to work we are doing. It reads public web pages only: a business’s own website, and job adverts on public job boards. From them it keeps what they say about the business, such as its name, its website, the tools its website uses and the roles it is advertising, and, for a watched page, its text and when it changed. These pages are about businesses, but some name a person, such as a sole trader or the contact on a job advert, and where they do, that name can be in what we keep. Our basis is our legitimate interest in finding businesses we can help and in following public changes that affect our work. Nothing from visitors to this site, and nothing from enquiries, is used for this.

Two providers process this for us. Browserless loads a public page in a browser on its own servers, so that a page which needs a browser can be read; it receives the page’s address and the page itself. Anthropic’s AI model, Claude, is given the text of a watched page before and after a change, so it can say in plain words what changed. Our system can also give it a business’s tools and the roles it advertises, so it can draft a short note on where we might help; that is switched off today. Neither provider is given anything from this site’s visitors or enquiries.

Nothing deletes these records automatically. We delete them by hand when they are no longer useful, or when you ask us to. To ask what we hold about you here, or to have it deleted, email hello@datum-forge.com.

Who processes data for us

Our hosting provider (Vercel) hosts the site, delivers the usage events described above to our own database, and stores the documents we share by private link; our database provider (Neon) stores the site’s data; our own installation of Umami, on its own Vercel project and its own Neon database, holds the detailed analytics of visitors who accepted them; our email delivery provider (Resend) sends our sign-in codes, enquiry notifications and the emails that carry a shared document’s link; Microsoft hosts our email; Browserless and Anthropic process the public pages our system reads, as described under “Businesses we research” above. A bot check from Cloudflare (Turnstile) may protect the enquiry form; it is not switched on today, and if it is switched on this notice will say so, because it processes your internet address and device information under Cloudflare’s own terms. Each provider acts on our instructions and none of them uses your data for its own purposes.

What we do not do

We do not sell personal data. We do not share it with anyone for their marketing. We do not make automated decisions about you. We do not build a profile of you from your visits.

Your rights

You can ask for a copy of what we hold about you, ask us to correct it or delete it, object to our using it, ask us to restrict it, and ask for it in a portable form. Email hello@datum-forge.com and we will answer within a month.

If you ask us to delete your enquiry, we remove it from our customer system with everything made from it: what you sent us, our record of it and our notes on it, your contact details, the company record if your enquiry was the only thing on it, and the measurement record that matched your enquiry to a campaign. We keep one line saying that an erasure was made, when and by whom, with nothing of what you sent in it. The email that told us about your enquiry sits outside that system, in our mailbox and our email provider’s log, and we delete it there by hand.

You can complain to the UK’s data protection regulator, the Information Commission (called the Information Commissioner’s Office until 30 September 2026), at ico.org.uk.
