Cookies and similar technologies
Cookies are small text files placed by a website or service. Browsers also provide localStorage and sessionStorage, which can remember information without using a traditional cookie. This policy covers all of these technologies.
Site preferences and choice storage
calclogichub:recent:v1stores recently opened calculator identifiers in localStorage until you clear site data.calclogichub:favorites:v1stores calculators you choose to favorite in localStorage until you remove them or clear site data.calclogichub:analytics-consent:v1stores your analytics choice in localStorage so the site can respect it on later visits.
These entries stay on your device and do not contain calculator inputs or calculated results.
Optional first-party analytics storage
If you select “Allow analytics,” __site_analytics_visitor stores a random identifier in localStorage and __site_analytics_session stores a random identifier in sessionStorage. The session value normally ends when the browser session closes; the visitor value remains until browser site data is cleared. They help count visits and sessions without storing calculator values or results. The analytics script does not load before permission and does not run when Global Privacy Control or Do Not Track is enabled.
Google advertising storage
Google AdSense and participating advertising vendors may use cookies, local storage, device identifiers, pixels, and similar technologies to deliver and measure ads, prevent invalid traffic, limit ad frequency, and personalize advertising where allowed. Cookie names and durations vary by vendor, region, browser, and whether you consent. The advertising consent message lists the vendors and purposes available for your region.
Use “Privacy & cookie settings” in the site footer to reopen an available Google consent message. You can also manage Google ad personalization in My Ad Center and review Google's cookie information.
Browser controls
Most browsers let you block or delete cookies and site storage. Blocking all storage may prevent favorites, recent-tool history, or saved privacy choices from working. Private-browsing modes may remove storage when the session ends. Global Privacy Control and Do Not Track prevent CalcLogicHub's optional first-party analytics from loading.
Changes and contact
Technology and vendor practices change, so this policy may be revised. The latest revision date appears above. For questions, email contact@calclogichub.com or review the broader Privacy Policy.
