What cookies and browser storage are
Cookies are small text files that websites can store in your browser and that are sent back to the server with each request. Local storage is a similar browser feature, except that the data stays in your browser and is never sent automatically. Both can be used for essential features or for tracking, which is why privacy laws regulate them.
What this website stores
| Name | Type | Category | Purpose | Duration |
|---|---|---|---|---|
cs-consent | Local storage | Necessary | Remembers whether you accepted or rejected optional categories, and when. | Until you withdraw consent or clear site data |
That is the complete list. The calculators do not store your expressions or history, and no cookies are set by this website.
Categories
Necessary storage (always on)
Needed so the site can respect your preference without asking on every page. It cannot be switched off, because without it your choice could not be remembered.
Analytics (optional, off by default)
Would allow aggregated statistics about how the site is used. No analytics service is currently installed.
Marketing (optional, off by default)
Would allow advertising or marketing measurement. No marketing service is currently installed.
If an optional service is ever added, it will be named here and in the cookie settings, and it will not run until you opt in.
Changing your choice
You can review, change or withdraw your choice at any time: . Withdrawing consent deletes the stored record, and the banner will ask again. You can also clear this website's data in your browser settings.
