Privacy

Sunplug is based in France. This is what it collects, why, and how to get rid of it.

What it collects

Your site's powerSolar, grid, house and battery, every thirty seconds

Your carsCharge level, whether plugged in, charging rate

Location, if you allow itOnly to check a car is at home

Your accountName, email, a passkey — never a password

Equipment credentialsEncrypted, used only to read your system

Why

To do the thing you signed up for: work out your surplus and charge your cars with it. That is the legal basis — performing the service you asked for, not consent that could be withdrawn while your car is mid-charge.

Optional extras are separate and genuinely optional. Car location is used for one question — is this car at your house — and Sunplug works without it.

What it does not do

Sell your data, or share it for advertising
Track you across other websites
Use third-party analytics, trackers or advertising cookies
Store your equipment passwords in readable form

Who else sees it

OVHcloud hosts the servers, in France. Cloudflare handles DNS. Neither does anything with your data beyond running the infrastructure.

Your equipment's manufacturers — Tesla, Enphase, Sungrow and so on — see the requests Sunplug makes on your behalf, under their own privacy policies. You granted that access and can withdraw it directly with them.

How long it is kept

Second-by-second readings7 days

Five-minute summaries400 days, so you can compare years

Daily totalsWhile your account exists, then 12 months

Your rights

You can ask for a copy of your data, ask for it to be corrected, or ask for all of it to be deleted. Deleting your account also revokes Sunplug's access to your car and inverter accounts — it does not leave a live token behind.

Email [email protected] and I will do it. If you are unhappy with how it was handled, you can complain to the CNIL, France's data protection authority.

A note on what this data is

Detailed electricity readings say more than they look like they do — when you wake, when you are out, how many of you there are. Sunplug samples every few seconds, which is finer than a smart meter. It is treated accordingly: kept on servers in France, not shared, and deleted when you ask.
