Cookie Policy

Local storage (always active)

• uch-theme — remembers light/dark mode.
• uch-favorites — calculators you starred (names and slugs only).
• uch-recent-calculators — recently used tools so you can find them again.
• uch-consent — your cookie choice itself.

These entries never leave your device and contain no personal data beyond the tool names you interacted with.

Cookies (consent required)

• Google Analytics — first-party analytics cookies (_ga, _ga_*) used only after you press “Accept all”. IP addresses are anonymized.
• Google AdSense — advertising cookies used only after consent, to measure and (where allowed) personalize ads.

Managing cookies

Pressing “Decline” in our banner blocks both analytics and ad scripts entirely — nothing loads, nothing is measured. To change your mind later, clear this site's data in your browser settings and refresh: the banner will ask again. Your browser also offers global controls such as Do Not Track and third-party cookie blocking, which we respect.
