Privacy and cookie notice
This notice explains how Kashif Limited handles information when you use Calculator786. Last reviewed: 15 October 2026.
Who operates this site
Calculator786 is operated by Kashif Limited, a company established in the United Kingdom. For privacy questions or requests, email kashkaz08@gmail.com. The registered office address, company number and place of registration must be completed before launch.
Information processed by the calculators
Calculator inputs and results are processed in your browser. The calculator application does not send those values to our server or create user accounts. If you use “Save as favourite”, the selected calculator names are stored in your browser’s localStorage on that device; clear browser site data to remove them. The application does not use localStorage for advertising consent. It also remembers your preferred currency and the calculators you opened recently in localStorage so the homepage can show them. To work offline, the site registers a service worker that stores copies of its own pages and files in your browser cache; clear site data to remove them.
The share feature creates a URL containing the input values you chose to share. Anyone with that URL may be able to read those values. The URL may also appear in your browser history and in the web-hosting request logs when opened. Do not share sensitive or identifying information in calculator links.
Hosting and technical logs
When a page is requested, the hosting and security providers may process technical data such as IP address, requested URL, timestamps, browser/device information and security events. The actual provider, processing locations and retention period depend on the deployment you choose; check and document those settings before launch. We do not currently have an account system or application analytics.
Cookies, advertising and similar technologies
In the no-ad build, the calculator application does not set advertising cookies or use third-party analytics. Browser localStorage used for favourites is not a cookie. Google AdSense and other advertising scripts are not enabled on this build. Do not enable advertising or analytics without updating this notice and configuring the applicable consent and opt-out controls first.
If advertising is enabled, use an appropriate consent-management platform and configure it for the locations and ad personalisation settings you serve. For users in the EEA, UK and Switzerland, verify the current Google-certified CMP requirements in AdSense Privacy & messaging before serving ads. Also configure legally required US state privacy choices and honour applicable opt-out preference signals. Advertising must remain disabled until those controls are working and tested.
International transfers
Hosting, security or advertising providers may process data outside the UK or the country where you use the site. The operator must identify the actual providers and countries and ensure any required transfer safeguards are in place. This build cannot determine your hosting region, provider contracts or transfer mechanism.
Your choices and rights
Depending on where you live and the circumstances, you may have rights to access, correct, delete, restrict or object to processing, request data portability, withdraw consent, or opt out of certain advertising uses. Contact us at kashkaz08@gmail.com. You may also complain to the UK Information Commissioner’s Office or your local supervisory authority. Browser controls can clear local favourites and saved URLs.
Retention and changes
The calculator application does not retain input values on our servers. Browser favourites remain until removed or browser site data is cleared. Technical-log retention is determined by the hosting and security providers and must be confirmed before launch. We will update this notice if the site’s data practices change.
