Privacy notice

Privacy by design, with local calculations.

This notice explains how Alibtikar Walhulul AlMumtazah (IHM) handles personal data when you visit this website. Calculator inputs and results stay in your current browser tab and are not received by the website operator.

Controller and contact

Alibtikar Walhulul AlMumtazah (IHM) is the company publisher and operator responsible for this website and its handling of personal data. AECEQ is managed from Saudi Arabia. Privacy questions and rights requests may be sent to [email protected].

Service address for legal notices: Building 6816, Eastern Ring Branch, Al Safa District, Riyadh 12856, Saudi Arabia.

Calculator information

Calculator inputs and results are processed by first-party JavaScript in the memory of your current browser tab. The application does not send them to a server, place them in a URL, or write them to cookies, local storage, session storage, IndexedDB, a service worker, or an application database.

Resetting or reloading the page clears the application state. If you copy, print, or download a result, you control and are responsible for the resulting clipboard content, printout, or file. Your browser, operating system, extensions, printer, or device may retain information independently of this website.

Ordinary website requests

To deliver any website, the browser sends technical information to the hosting and content-delivery provider. This can include an IP address, request date and time, requested URL, browser and device headers, referring page, TLS and network-security information, and records needed to detect abuse or keep the service available.

The site is a static deployment intended to be hosted through Cloudflare. It has no application server, account system, contact form, analytics script, or error-monitoring SDK. Cloudflare may process network and security information under its applicable service terms, data-processing terms, privacy notice, and configured service settings.

Advertising is not enabled and no advertising provider is configured. The site publishes no advertising script, no advertising identifier and no site-verification tag.

Purposes and legal bases

Technical request and security information is processed as necessary to deliver the pages, maintain availability, prevent abuse, investigate faults, and protect the website and its users. The legal basis is the controller’s legitimate interests in operating a secure and reliable public website, except where processing is necessary to comply with a legal obligation.

The website does not use personal data for automated decision-making, profiling, behavioural advertising, or sale. No advertising request is made and no advertising identifier is set or read.

Calculator results do not produce legal or similarly significant effects and are not decisions made by the operator about an individual.

Recipients, transfers, and retention

Technical website data may be handled by Cloudflare and its authorised subprocessors. Processing locations and transfer safeguards depend on the services and account settings actually used. Where a transfer outside the EEA requires safeguards, the relevant provider terms may use an adequacy decision, approved contractual safeguards, or another lawful transfer mechanism.

The application creates no visitor account or application log database. Technical and security records are retained only for the periods applied by the hosting service and its configured products, or for longer where necessary to investigate security incidents, establish or defend legal claims, or comply with law. This notice will be updated before any operator-controlled visitor logging or additional provider is enabled.

Your rights

Depending on the circumstances, you may request access, rectification, erasure, restriction, portability, or object to processing. Send a request to [email protected]. The operator may need proportionate information to verify the request and may be unable to identify calculator information that never left your device.

You may complain to a competent data-protection supervisory authority under applicable law. You also have the right to withdraw consent at any time where consent is the legal basis; this website asks for no optional storage or advertising consent, so there is currently no consent to withdraw.

Children and changes

The website is intended for a professional and educational built-environment audience and is not directed to children. Do not submit personal data about children or other people through support correspondence.

Material changes to the data flows are reflected in this notice before the relevant feature is enabled. This notice is generated from the same build settings that decide whether advertising runs, so it cannot describe a state the deployment is not in. Adding analytics, accounts, forms, or server-side calculation would require a new privacy review.
