PRIVACY NOTICE

Privacy, plainly.

Omar Calc is a client-side calculator created by Omar Hosny. This notice describes what the site does as of 20 September 2026.

What is stored on your device

Your expression history and the small privacy-notice preference are saved in your own browser using local storage. They are not sent to Omar Calc’s application. You can clear them with “Clear history” or your browser’s site-data controls.

Hosting and security data

The hosting and security providers necessarily receive ordinary connection data such as an IP address, browser details, requested page and time of request so they can deliver and protect the site. Cloudflare may set a strictly necessary security cookie such as __cf_bm to distinguish legitimate traffic from automated abuse. Omar Calc does not read this cookie or use it for advertising or analytics.

What Omar Calc does not collect

There is no account, sign-in, contact form, newsletter, advertising, analytics, tracking pixel, fingerprinting or payment feature. The site has no images or embedded third-party media.

Links and sharing

The footer links to Omar’s website and email address. Those destinations apply their own practices after you choose to open them. “Share solution” uses your device’s share feature only after you press it; where sharing is unavailable, it copies the solution to your clipboard instead. Omar Calc does not receive the shared content or learn where you send it.

Legal note and contact

This is a plain-language notice, not legal advice. If the site later adds accounts, analytics, forms or other processing, this notice must be reviewed. Egyptian Personal Data Protection Law No. 151 of 2020 and other applicable rules may apply depending on future use and audience. Questions: contact@omarhosny.work.gd.
