This Declaration supplements, but does not replace, any separate agreement you may have with Octopus Energy regarding their services.
8. Website Cookies
This section covers the octomiser.com website, not the app.
The website uses Google Analytics to count visits and see which pages help. Google Analytics cookies (_ga and _ga_*, which last up to two years) are set only after you click Accept analytics in the cookie banner. If you reject or ignore the banner, no analytics cookies are set and the website works the same.
You can withdraw your consent at any time with the Cookies button in the bottom-left corner of the page: choose Reject analytics and Google Analytics stops and its cookies are removed.
Your choice is kept in your browser's local storage so the website does not ask again on every visit.
