Lightmeter is an Open Source company, and we care about ethics. In collecting data, we only aim to improve Lightmeter products and make them more useful to our users, and when doing so, we always use Open Source software, and our own private European servers.

We collect data in 3 places:

  • On our website, to know if it’s popular, where visitors come from for example, from a forum or a news site – so we know where to direct our marketing and communication and where to help people who have questions. We also store data to be able to block or slow down attacks on our infrastructure – the web is a dangerous place. And, lastly, for legal reasons. All this data we store on our own servers, to which only we have access. We don’t store any data to sell, or use for ads, or share with anyone else. If you notice third party services which might collect data, please let us know.
  • Our newsletter, forum, marketing automation and other communication places, to enable those systems to operate effectively. To log in somewhere, you need a cookie, and to send you mail, we need to know your email. We don’t upload your data to facebook/twitter to target ads or similar sadly common practices, nor share it with anyone else. We run, where possible, all these services ourselves, so we don’t have to hand it over to a third party.
  • Our software collects some information we need to improve its functioning. For example: what web browsers are used to access it, what are popular features, what is a typical email bounce rate – so that we understand the needs of typical users, and ensure Lightmeter can do what they need. This is automatically disabled for web browsers which have “Do Not Track” enabled.
