Cookie Policy

A cookie is a small file a website asks your browser to keep, then reads back on a later visit. It is the mechanism behind staying signed in, and also behind being followed around the internet by an advert for a chair you already bought.

Local storage does a similar job by a different mechanism. It is not a cookie, it does not travel with your requests, and it never leaves your device, but it is disclosed here anyway because the distinction matters far less to you than the behaviour does.

No cookies are set by Calculator, and nothing here follows you to other sites. There is no consent banner because there is nothing to consent to.

Every browser can block or clear cookies, usually under privacy or site settings, and most let you do it per site rather than everywhere at once.

There is nothing here to block, though clearing site data will remove anything the app has saved locally, including saved progress.
