Cookie Policy

Understanding the storage inventory

Theme and pinned measurements stay on this device until removed. Unpin or clear saved values in each calculator, or clear site data in your browser.

Cookies, localStorage, page memory and infrastructure logs are different technologies. localStorage is not automatically attached to page requests; page memory is lost on navigation.

The inventory distinguishes requested device features from inactive optional services. Inactive services do not set their cookies through this application. Browser controls can remove stored site data.

Your choices and withdrawal

Optional analytics and advertising are inactive, so no choice is needed to enable the calculators. Requested theme preferences and measurement pins remain under your control.

If optional services are activated later, information about their purposes and available choices will be provided. Where consent applies, it can be withheld or withdrawn; withdrawal concerns future processing and does not undo earlier lawful processing.

Optional audience and performance analytics

Optional GA4 and Cloudflare Web Analytics are inactive. If enabled, they would process page and device information after applicable consent. Calculator inputs and results are not part of CalcSlope’s analytics event payload.

Prepared events describe calculator actions using only registered tool, language, mode, unit-system and status categories. They exclude measurement values, email, custom user IDs, query strings and full referrers. Analytics and advertising purposes are handled separately.

Planned advertising — currently inactive

AdSense advertising is planned and currently inactive. No advertising script is loaded by this application. Ownership verification, ads.txt and permission to serve advertisements are separate matters.

If advertising is introduced, Google and participating vendors may use cookies and identifiers to deliver and measure advertisements based on visits to this and other sites, including personalization where permitted. The applicable vendors, disclosures and choices will be provided before activation.

How long information is kept

Unpinned measurements stay in temporary page memory and are lost on reload or navigation. Selected theme preferences and explicitly pinned measurements in localStorage have no application-set expiry and remain until removed, overwritten, or cleared through your browser settings.

Cloudflare Pages retains build caches for 7 days after last read date, while real-time deployment logs are ephemeral. Core edge requests process IP addresses ephemerally for security and routing without indefinite raw log retention; customer-controlled log retention depends on account settings and is verification pending.

Cloudflare Web Analytics documents a 7-day retention period for unsampled beacon data and up to 6 months for aggregated metrics, but is currently inactive. Optional Google Analytics 4 is likewise inactive. Communications sent to [email protected] are retained only as long as necessary to address your enquiry or meet statutory recordkeeping duties.

Dates and changes

This information may change when the service, providers, purposes or storage practices change. The update date shown above identifies the current text.

Material changes to optional collection will be explained before activation. New consent will be requested where required by applicable law.
