Cookie Policy
Last updated: October 5, 2026.
We set no cookies
Calculate All does not set any cookies of its own — no analytics cookies, no advertising cookies, no tracking cookies, no consent banner needed. Your visit leaves no cookie trail on our end.
What we store on your device instead
A few conveniences use your browser's localStorage, which — unlike cookies — is never sent to any server. It stays entirely on your device:
| Stored item | Purpose | When it's saved |
|---|---|---|
Theme preference (calc-theme) | Remembers dark / light mode | When you toggle the theme |
Favorites (calc-favs) | Your saved calculators | When you press ♡ Save |
History (calc-history) | Recent calculations | Automatically, on each calculation |
Display name (calc-profile) | Optional nickname in the profile popover | Only if you enter one |
| Newsletter dismissal | Remembers you closed the signup prompt | When you dismiss it |
Third-party cookies
We embed no third-party content that sets cookies: no social widgets, no ad networks, no analytics beacons. If that ever changes, this policy will be updated before any third-party code is enabled.
How to clear your stored data
Because everything is stored locally, you are in full control:
- Chrome / Edge: Settings → Privacy and security → Delete browsing data → choose "Cookies and other site data" (this includes localStorage).
- Firefox: Settings → Privacy & Security → Cookies and Site Data → Clear Data, or right-click the page → "Forget About This Site".
- Safari: Settings → Privacy → Manage Website Data → remove the site.
Clearing site data removes your theme choice, favorites, and history permanently — they cannot be recovered, because we never had a copy.
