Privacy

Plain English on what we collect, why, and the control you keep over it.

Last updated: July 2026

Who we are

Biofaze is an invite-only health app run from the United Kingdom. This page explains how we handle your personal data under UK GDPR and the Data Protection Act 2018. Any questions, email hello@getbiofaze.com.

What we collect

Before you have an account, the only thing we collect is the email address you leave to join the waitlist. Once you're in the app, we also store the data you choose to enter, food logs, workouts, weight, sleep and any wearable data you connect, so the app can work for you.

Why we collect it

Your waitlist email is used for one thing: to send your invite and the occasional beta update. Your in-app data is used only to run the features you're using, showing your numbers, tracking your progress and powering your coaching. Nothing more.

Legal basis

We rely on your consent for the waitlist email, which you can withdraw at any time by unsubscribing, and on performance of a contract to run the app once you hold an account.

Where it's stored

Your data lives in our managed database (Supabase). Every row is locked to your account with row-level security, so other users can't see it. We don't sell your data, we don't share it with advertisers, and we don't hand it to third parties for their own purposes. Our infrastructure providers (Supabase and Vercel) may process data outside the UK; where they do, the transfer is covered by their standard contractual safeguards.

How long we keep it

Your waitlist email is kept until you receive your invite or unsubscribe, whichever comes first, and then removed. Account data is kept while your account exists and deleted when you ask us to delete your account.

Children

Biofaze isn't aimed at under 18s and we don't knowingly collect their data. The free calculators are written for adults; children and teenagers should use age-appropriate NHS resources instead.

Your rights

Under UK GDPR you can ask us to show you the data we hold, correct it, export it, or delete it. To delete your account and everything in it, email hello@getbiofaze.com and we'll action it. You can leave the waitlist at any time using the unsubscribe link in any email.

Free tools

Our free calculators, TDEE, BMI and sleep, run entirely in your browser. Whatever you type into them, height, weight, ethnic background or wake times, is used for the maths on your screen, never sent to us and never stored. The only thing a tool page can collect is the email address you choose to leave for the waitlist.

Cookies and analytics

We use privacy-friendly, aggregate analytics to understand how the site is used. Our analytics are cookieless, and the marketing site and free tools set no advertising or tracking cookies at all, which is why you don't see a cookie banner: there's nothing to consent to. We don't run advertising trackers and we don't build a profile of you across other sites.

Changes

If this policy changes we'll update the date at the top of this page, and flag anything material to account holders by email.
