What you enter stays in your browser
The calculator runs entirely on your own device. Your consumption, your solar panels, your tariffs and the result are not sent to a server and are not stored by us.
No cookies, no tracking
This site sets no cookies, uses no analytics services or advertising networks and loads no fonts or scripts from other parties. That is also why you see no cookie banner.
A link with your calculation
When you change the inputs, your settings are added to the web address after the hash sign (#). That lets you save or share a calculation. Your browser does not send that part of the address to the server. Anyone you give the link to will see the values you entered.
Server logs
As with any website, the hosting provider may record technical data when a page is requested, such as IP address, time and the page requested. This data is needed to keep the site secure and available and is not used to track visitors.
Links to other websites
The source references link to other parties' websites. The privacy policy of the organisation concerned applies there.
