Privacy

What personal data we hold, why, and your rights.

Who we are

Kilowatt Club Ltd, registered in England and Wales, company number 17403274. Registered office: 30 Pleydell Avenue, London, England, W6 0XX. Contact: rob@kilowattclub.co.uk.

What we collect, and why

• Waitlist. Your email, postcode, and what you tell us about your home, tariff and kit. We use it to see whether we can help and to email you about joining, because you asked us to.
• Members. The Google email you sign in with; your battery’s readings and plans, sent by the Brain in your home (charge, power, half-hourly import and export, Axle events); and the date and amount of each membership payment. We use it to run your dashboard, work out your savings and keep your membership up to date, as part of our agreement with you.
• Cookies. Signing in sets a cookie that keeps you signed in. We don’t use advertising or analytics cookies.

Your dashboard is private unless you agree to make it public.

Who sees it

We never sell your data. It is held by the companies that run our systems: Vercel (website), Neon (database), Google (sign-in, email and the fonts on our pages) and Monzo (membership payments). They may process it outside the UK.

The Brain in your home fetches prices from Octopus, events from Axle and weather from Open-Meteo directly. We don’t pass your details to them.

How long we keep it

• Waitlist details: until you join or ask us to delete them.
• Member data: while you’re a member. If you leave, ask and we’ll delete it.
• Payment records: six years, as tax law requires.

Your rights

You can ask for a copy of your data, ask us to correct or delete it, or object to how we use it. Email rob@kilowattclub.co.uk. If you’re unhappy with our answer, you can complain to the Information Commissioner’s Office at ico.org.uk.
