Privacy

We want to know as little about you as possible. We don't store your name, address or email address, unless you later ask us to.

The check isn't live yet

You can't upload a quote yet. Where this statement describes the check, it describes how we will handle your data once the check works.

Server logs

Like every website, our server records some technical data for each visit, such as your IP address, the page you asked for and the time. We use this to keep the site running and secure, and to count visits per page in total, without building profiles of individual visitors. The log has a fixed maximum size, and old entries are overwritten automatically. We don't share it.

Your quote

Once the check works, we will take the details we need from your quote: price, capacity, power and the promised savings. Before anything goes to a language model (AI), we will black out your name, address, phone number, email address, bank account number and signature. We will delete the file itself as soon as the details have been read, and only keep the figures, without a name or address.

Your postcode

When the check asks for your postcode, we will only keep the 4 digits, not the letters. That is enough to find subsidies in your area.

Meter data

When you add a file with your meter readings, we read it in memory and never save the file. The hourly values are used for the calculation and then discarded. We keep only totals, such as your yearly usage and the period the file covers, together with your result. They are deleted with it.

Language model (AI)

The check will use a language model to read your quote and to write the result in plain language. It will not calculate the figures; our own calculation module does that. We will choose a provider with servers in the EU, or one that stores nothing (zero retention), and we will sign a data processing agreement with that provider before the check goes live.

Cookies and statistics

  • No tracking cookies and no advertising networks.
  • We set the cookie en_ref only when you come via an energy advice desk. It only holds the name of that desk and lasts 30 days. We use it only to hide links we earn money from and the request for a contribution.
  • If you close the language hint, the cookie en_lang_hint remembers that for a year. It holds nothing about you.

Email

Right now we don't ask for your email address. If we later offer email updates, for example when your result has been updated, we will only store your address if you ask for it, and you will be able to have it deleted with one click.

Your rights

Under the GDPR you may ask which data we hold about you and have it deleted. Because we store no names or addresses, there is usually nothing to link to you. A contact address will follow before launch. You can also file a complaint with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens).
