1. Introduction
Welcome to HDCalculator.com (“HDCalculator,” “we,” “us,” or “our”).
HDCalculator.com is a free online website that provides calculators and other useful tools. Visitors can access our tools without purchasing a product, making a payment, or creating an account.
This Privacy Policy explains how information may be collected, processed, used, stored, or shared when you visit or use our website.
We aim to respect your privacy, collect only information necessary for legitimate website purposes, and explain the role of hosting infrastructure and third-party services that may process information when the website operates.
By using HDCalculator.com, you acknowledge that you have had the opportunity to read this Privacy Policy. Where applicable law requires consent for a particular activity, your use of the website alone will not be treated as a substitute for that consent.
2. Information We Collect
2.1 Personal Information You Provide
You can generally use HDCalculator.com without providing your name, telephone number, home address, or other identifying information.
We do not require visitors to register, create profiles, log in, or complete payment transactions to use our calculators and tools.
If you contact us through our designated contact us page or email address, we will receive the information you choose to include in your message, such as your email address and the contents of your inquiry.
We do not intentionally request personal information merely to allow visitors to perform ordinary calculations.
2.2 Information Entered into Calculators and Tools
Our website provides calculators and tools that may require visitors to enter numerical values or other information to generate results.
Depending on how an individual tool is technically implemented, the information entered may be processed within your browser, transmitted to our servers, or processed by a service that supports the tool.
We do not represent that every calculator necessarily processes all entered values exclusively on your device.
We do not intentionally use calculator entries to identify visitors, create user accounts, or build personal profiles for unrelated purposes. However, the way a particular tool handles entered information must be considered alongside any associated scripts and technical services.
Please avoid entering names, identification numbers, or other information that identifies you or another person unless it is genuinely necessary and you understand how the relevant tool processes that information.
2.3 Information Processed Automatically
When you visit a website, certain technical information may be processed automatically by its hosting infrastructure, security services, or other technical providers.
Depending on the services configured for HDCalculator.com, this may include:
Internet Protocol (IP) address.
Browser type and version.
Device and operating system information.
Pages and resources requested.
Referring webpage or website.
Date, time, and duration of requests.
Technical errors, performance information, and security events.
Approximate location that may be inferred from an IP address.
Such information may be processed to deliver website pages, maintain security, detect abuse, troubleshoot technical problems, and improve website reliability.
The actual information processed, and whether it is accessible to the website operator, depends on the hosting, security, and other services in use.
3. Cookies and Similar Technologies
HDCalculator.com may use cookies or similar technologies depending on the website features and third-party services that are enabled.
Cookies are small files stored in your browser or on your device. Similar technologies may store or access information to support website functions, preferences, analytics, or advertising.
Depending on the technologies actually used, these may include the following categories:
Essential technologies: Technologies necessary for website delivery, security, network communication, or other essential functions.
Preference technologies: Technologies that remember settings or preferences, where such features are available.
Analytics technologies: Technologies that help measure website traffic, understand general usage patterns, or identify performance problems, if analytics services are enabled.
Advertising technologies: Technologies that may help display, measure, or personalize advertisements if third-party advertising services are enabled.
The specific cookies and similar technologies used by the website depend on its actual configuration. We will provide appropriate disclosures and obtain consent where required by applicable law.
Where consent is required for non-essential cookies or similar technologies, those technologies should not be activated before valid consent is obtained.
You may be able to manage or delete cookies through your browser settings. Where a consent-management tool is provided, you can also use it to manage the relevant preferences.
Blocking certain technologies may affect the availability or operation of some website features.
4. Google AdSense and Third-Party Advertising
HDCalculator.com is intended to provide free tools to its visitors. Advertising may be used to support the operation and maintenance of the website.
The availability of Google AdSense or any other advertising service depends on whether the relevant service has actually been implemented. This Privacy Policy does not, by itself, establish that a particular advertising service is currently active.
If Google AdSense or another advertising service is enabled, third-party advertising providers, including Google where applicable, may use cookies, web beacons, IP addresses, device identifiers, or similar technologies in connection with advertising.
Depending on the provider’s configuration and applicable settings, these technologies may be used to:
Display advertisements.
Measure advertising performance.
Limit repeated advertisements.
Detect invalid advertising activity.
Deliver personalized or non-personalized advertisements.
Use information about visits to this website or other websites to support advertising activities.
Google and its advertising partners may process information under their respective privacy policies and service arrangements. HDCalculator.com does not control every aspect of their independent data-processing practices.
If Google advertising is enabled, visitors can review how Google uses data when using partner websites and apps:
https://policies.google.com/technologies/partner-sites
Visitors can also review or manage Google’s advertising personalization settings at:
https://adssettings.google.com/
Further information about opting out of certain third-party interest-based advertising is available at:
https://www.aboutads.info/choices/
The availability and effect of these controls may vary by provider, device, browser, and jurisdiction.
Where required, we will provide an appropriate consent mechanism, identify relevant advertising providers, and obtain valid consent before enabling technologies that require consent.
5. How We Use Information
Information processed in connection with HDCalculator.com may be used, where applicable, for the following purposes:
To provide calculators, tools, and requested results.
To deliver website content and maintain technical functionality.
To maintain website security and prevent abuse.
To identify and resolve technical errors.
To monitor and improve performance where appropriate analytics are enabled.
To display and measure advertisements if advertising services are enabled.
To respond to messages sent to our contact address.
To comply with applicable legal requirements and protect legitimate rights.
We do not intentionally collect personal information simply to require visitors to identify themselves before using our ordinary tools.
6. Sharing of Information with Third Parties
HDCalculator.com does not sell physical products, digital products, subscriptions, or paid services through the website. We do not intentionally sell personal information.
However, operating a website may involve third-party service providers that process information as part of delivering technical services.
Depending on our actual configuration, these providers may include hosting companies, security providers, content-delivery services, analytics providers, and advertising partners.
Information may be processed or disclosed to these providers to the extent necessary for their services, subject to applicable law and relevant service arrangements.
If advertising or analytics technologies are enabled, information may be made available to third parties through cookies, scripts, network requests, or other technical mechanisms.
Certain privacy laws define “sale,” “sharing,” or targeted advertising more broadly than a conventional sale for money. The legal classification of a particular data disclosure depends on the technology, purpose, applicable law, and circumstances.
Where applicable law requires notice, consent, or an opt-out mechanism for these activities, we will provide the required information and controls.
We do not intentionally disclose calculator entries for unrelated purposes. However, their handling depends on the technical design of the individual tool and the services supporting it.
7. Data Storage and Retention
We aim to retain personal information only for as long as reasonably necessary for the purpose for which it was processed, including website operation, security, troubleshooting, and legal compliance.
Information held by hosting providers, security services, or other third parties may be subject to their own retention practices and contractual arrangements.
Technical records may be retained for different periods depending on their purpose, such as identifying security incidents or resolving technical problems.
We do not assign a universal retention period to every type of information where the applicable technical configuration and provider practices may differ.
Where applicable law grants individuals a right to request deletion of their personal information, we will consider and respond to such requests in accordance with the relevant legal requirements and any applicable exceptions.
8. Data Security
We take reasonable steps, appropriate to the website’s operations, to protect information against unauthorized access, misuse, loss, alteration, and disclosure.
Security measures may include appropriate access controls, software maintenance, secure communications, and protective measures provided by relevant hosting or security services.
No website, internet transmission, or electronic storage system can be guaranteed to be completely secure. We therefore cannot promise absolute security.
Where a security incident triggers a legal notification obligation, we will address that obligation in accordance with applicable law.
9. International Data Processing
The hosting infrastructure and third-party service providers supporting a website may operate in countries other than the visitor’s country of residence.
As a result, information may be processed or stored internationally, depending on the providers and infrastructure used by HDCalculator.com.
Where applicable data-protection laws restrict international transfers, the relevant parties must use an appropriate transfer mechanism or satisfy another permitted legal condition.
The locations and transfer arrangements applicable to this website depend on the services actually configured.
10. Your Privacy Rights
Your privacy rights depend on your location, the nature of the information involved, the activities conducted by HDCalculator.com, and whether a particular law applies to the website operator.
Where applicable, your rights may include:
Access: Request information about personal data processed about you.
Correction: Request correction of inaccurate personal information.
Deletion: Request deletion of personal information, subject to applicable exceptions.
Restriction or objection: Request restriction of certain processing or object to processing where the law provides that right.

Some requests may be subject to legal limitations or exceptions. We will explain any applicable restriction where required.
11. Region-Specific Privacy Information
11.1 European Economic Area and United Kingdom
Where the GDPR or UK GDPR applies, individuals may have rights including access, rectification, erasure, restriction of processing, data portability, objection, withdrawal of consent, and the right to complain to a competent supervisory authority.

11.2 United States
Certain US state privacy laws provide rights relating to access, deletion, correction, targeted advertising, sale or sharing of personal information, and other covered processing activities.
These rights apply only where the relevant law covers the website operator and the circumstances in question. Additional requirements may apply to privacy notices, opt-out methods, and recognition of legally prescribed opt-out signals.

12. Children’s Privacy
HDCalculator.com is not intended to be a service specifically designed to collect personal information from children under 13.
We do not intentionally request personal information from children merely to enable ordinary use of our calculators and tools.
If we become aware that personal information has been collected from a child in circumstances requiring deletion or additional protections, we will take appropriate steps in accordance with applicable law.
Where a law such as the United States Children’s Online Privacy Protection Act applies, additional requirements concerning parental notice, consent, data use, retention, and disclosure may apply. This general statement does not replace those requirements.
Parents or guardians who believe that a child has provided personal information may contact us using the details in Section 17.
13. Third-Party Websites and Services
Our website may contain links to external websites or use third-party services to deliver certain features.
Those websites and services may operate under separate privacy policies and terms.
HDCalculator.com does not control the independent privacy practices of external websites. We encourage visitors to review the applicable policies of third-party services before providing information or interacting with them.
14. Automated Decisions and Profiling
HDCalculator.com provides calculators and tools that generate results based on the information entered by a visitor.
A calculation result is not, by itself, an indication that the website creates a personal profile of the visitor.
If analytics, advertising, or other third-party technologies are enabled, those providers may perform activities according to their own services and applicable settings. Any processing subject to specific automated-decision or profiling rights will be handled in accordance with applicable law.
15. Changes to This Privacy Policy
We may update this Privacy Policy when our website, technical services, advertising arrangements, or legal obligations change.
The revised policy will be published on this page, and the “Last Updated” date will be amended accordingly.
If a change requires additional notice or consent under applicable law, we will provide that notice or obtain consent as required.
We encourage visitors to review this page periodically.
16. Disclaimer Regarding Legal Requirements
This Privacy Policy is intended to explain the website’s information-handling practices in clear language.
Its publication does not automatically establish compliance with every privacy, cookie, advertising, or data-protection law in every country.
Our actual practices, technical configuration, third-party arrangements, consent mechanisms, and applicable legal obligations must be considered together.
