Privacy
Calculate without handing over your life.
WattWorth is designed to work without an account, a name or an email address.
What stays on your device
Numbers entered into calculators, currency preferences and the optional My Year profile are stored in your browser so pages can reuse them. They are not sent with the calculator result.
What the site counts
A random anonymous browser identifier is stored locally and sent to count an approximate unique browser once. Per-page calculation counters store only the page name and a total number — not your answers.
Optional analytics
The site can use privacy-focused aggregate analytics when configured by the operator. It is used to understand page popularity and technical performance, not to build personal profiles.
External and partner links
Clearly labelled partner and channel links open third-party services with their own privacy terms. Some partner links may earn the site a commission without changing the visitor's price.
Your control
Clear site data in your browser to remove the saved profile, preferences and anonymous identifier. Blocking local storage may disable persistence but the calculators still work.
