PRIVACY INFORMATION

Privacy for this free tool.

Contrastclear performs its calculations on your device. No account, contact form or server-side calculation service is used.

Calculator data

The calculator does not submit your colour inputs to an application server for calculation. A shared colour link puts the colours and preset in a URL; opening that link can expose those values through hosting requests. This release does not save inputs in cookies or local storage. Reloading a plain calculator URL restores its illustrative defaults; a valid shared URL restores the colours and preset encoded in that link. Copying places a result on your clipboard only after you select Copy. Downloading a text report creates a file on your device; your browser handles that download.

Colour links

Get colour link only fills a link field on this page. The URL contains the chosen foreground, background and preview preset. Opening it can include those URL values in hosting requests; sending it makes them visible to its recipients. This site does not post or send the link for you. Invalid or unsupported links do not silently establish a valid contrast result.

Hosting and technical requests

Cloudflare Pages delivers these static pages. Like other web hosting, delivery involves technical request information such as an IP address, requested URL, time and browser details. Cloudflare handles that processing under its own policies. Read Cloudflare’s privacy policy for more information.

Advertising and analytics

This release does not load advertising, third-party analytics or optional tracking scripts. Publisher identification in the page and ads.txt prepares the site for a later advertising review; it does not mean ads are serving. If advertising or analytics is enabled later, this notice and any required consent setup must be updated for this host first.

Email enquiries

The public contact address yardfill.helpful594@aleeas.com is an existing shared portfolio alias. It forwards through SimpleLogin to the operator’s mailbox. Emailing shares your sender address, message and any attachments with the forwarding service and the receiving mailbox. Include only what is needed for your enquiry. Read SimpleLogin’s privacy policy.

Your choices

You can use the calculator without contacting anyone or downloading a file. To ask about an email you have sent or request deletion from the operator’s mailbox, use the same contact address. The operator can address records it controls; hosting and email providers handle their own processing.
