WattFigure does not ask you to create an account, and does not collect names, email addresses or payment details. Calculators run entirely in your browser; the values you type are never transmitted to us and are not stored anywhere.
Analytics
We use privacy-friendly aggregate analytics to count page views. No cookies are set for this purpose and visitors are not tracked across other sites.
Advertising
Pages may display ads served by third-party ad networks. Those networks may use cookies or similar technologies to serve and measure ads, including personalized ads where you have consented to them. You can review and change your choices through the consent controls presented to you, and through your ad settings with the relevant provider. Where the GDPR, UK GDPR or CCPA/CPRA apply, you have the right to access, correct, delete or opt out of the sale or sharing of personal information; contact us at hello@wattfigure.com to exercise those rights.
Affiliate links
Some outbound links to retailers are affiliate links. If you follow one, the retailer may set its own cookie to attribute a purchase. We receive commission reports in aggregate and do not learn what you bought.
Children
This site is not directed at children under 13 and does not knowingly collect information from them.
