How we work together

A named lead.
A second pair of eyes.
You at the table.

We agree who owns your sprint before it starts. Your lead drives the build, another team member reviews the agreed flow, and you help make the decisions that depend on knowing your customers and business.

Privacy

Your information.

We measure how this site is used, so we can tell who is genuinely interested and reply properly. This is our own first-party measurement — no advertising networks, no data sold or shared with anyone.

What we record. The pages you open and for how long, how far you scroll, what you click, which sections you linger on, text you copy, where your cursor moves on the page, your approximate city, the network or company your connection belongs to, your browser, device, screen, timezone and language, and the link or site that sent you here. We store an identifier on this device, in cookies and in browser storage, for two years, and a technical fingerprint of the device so we still recognise you if that storage is cleared. We never record what you type, apart from an email address you choose to submit.

How we know your name. If you arrived from a link we sent you, that link identifies you. Emails we send may contain a small image that records when the message was opened. If you give us your email address here or in the project brief, we connect it to the visits you made before that, including the anonymous ones.

The project brief opens Typeform, where the provider’s privacy terms also apply. Email links open your email app; nothing is sent automatically.

You can ask for a copy of everything we hold about you, or have all of it deleted, by writing to hello@buildbyfriday.com. We delete it in full, and you do not have to give a reason.
