Privacy Policy

1. Scope of this Privacy Policy

This Privacy Policy applies to the Calculation Portal website located at CalculationPortal.com and to personal information processed in connection with operating, securing, analysing and improving the website.

It applies to visitors who use our calculators, converters, estimators, analysers, reference materials, articles, contact facilities and other website features.

This policy does not govern the independent privacy practices of third-party websites, platforms or services that you may reach through links on Calculation Portal.

2. Who Is Responsible for Your Information?

The operator of CalculationPortal.com is responsible for determining how and why personal information collected directly through the website is processed, except where another organisation independently determines its own processing purposes.

Privacy enquiries can be submitted through our Contact page.

3. Information We May Collect

The information processed in connection with Calculation Portal depends on how you interact with the website. It may include:

• technical information associated with your browser or device;
• IP address and related network information;
• browser type and version;
• device type and operating system;
• pages requested and referring pages;
• timestamps and request information;
• approximate location derived from network information, where applicable;
• cookie or similar technology identifiers, where used;
• website interaction and performance information;
• information you voluntarily provide through a contact form or email;
• consent choices and privacy preferences; and
• information reasonably required to maintain website security and prevent abuse.

We do not require visitors to create an account merely to use the public calculators and reference resources currently offered by Calculation Portal.

4. Calculator Inputs and Results

Calculation Portal provides interactive calculators, converters, estimators, analysers and related tools. Many calculations can be performed directly within your web browser.

Calculator fields may sometimes involve information that could be personal in a particular context. For example, a visitor might enter financial, property, salary, age, health-related or other values into a calculator.

You should avoid entering names, account numbers, identification numbers, passwords, medical record identifiers or other information that directly identifies a person unless a particular tool explicitly requires that information and explains how it will be handled.

Where a calculator operates entirely within your browser, the values you enter may be processed locally for the purpose of producing the requested result rather than intentionally being stored as a user profile by Calculation Portal.

However, ordinary web infrastructure may still generate technical request, security, diagnostic or analytics information when a calculator page is accessed. The fact that a calculation runs locally therefore does not mean that no technical information whatsoever is processed during your visit.

5. Automatically Collected Technical Information

When you request a page or resource from CalculationPortal.com, our hosting, security, caching and web infrastructure may automatically process information required to deliver the website and maintain its security and reliability.

This may include:

• IP address;
• date and time of a request;
• requested URL;
• HTTP status information;
• browser and device information;
• referring URL;
• network and server diagnostic information;
• security events and suspected malicious activity; and
• performance and caching information.

Such information may be contained in server logs or security systems and may be necessary for website delivery, troubleshooting, fraud prevention, abuse prevention and security.

6. Information You Provide to Us

If you contact Calculation Portal, we may receive information such as your:

• name;
• email address;
• message;
• subject or reason for contacting us;
• information about a calculator or page you report;
• attachments or supporting information you voluntarily provide; and
• related correspondence.

Please do not send sensitive personal information unless it is genuinely necessary for us to deal with your enquiry.

7. How and Why We Use Information

Depending on the circumstances, information may be processed to:

• provide and operate CalculationPortal.com;
• deliver requested pages, tools and resources;
• perform or display calculations requested by visitors;
• respond to questions, feedback and correction reports;
• diagnose technical problems;
• maintain website and network security;
• detect spam, fraud, malicious requests or abuse;
• understand website performance and reliability;
• understand how visitors use the website where permitted;
• improve calculators, navigation, content and user experience;
• remember privacy or website preferences where appropriate;
• measure advertising or website performance where permitted and enabled;
• comply with legal and regulatory obligations;
• establish, exercise or defend legal claims; and
• protect our rights, visitors and website infrastructure.

8. Lawful Bases for Processing

Where UK or European data protection law requires a lawful basis for processing personal data, the basis used will depend on the particular processing activity.

Where processing is based on consent, you may withdraw that consent in accordance with applicable law. Withdrawal does not make processing carried out before withdrawal unlawful.

9. Cookies and Similar Technologies

Calculation Portal may use cookies, local storage, tags, pixels, scripts or comparable technologies for website operation, security, preferences, measurement and, where enabled, advertising.

Strictly necessary technologies

Some technologies may be necessary for functions such as security, network management, consent management, load balancing or remembering settings necessary to provide a service requested by the visitor.

Analytics technologies

Where analytics services are enabled, analytics technologies may help us understand matters such as page usage, navigation, website performance and errors.

Advertising technologies

If advertising is introduced, advertising providers may use cookies or similar technologies for permitted purposes such as ad delivery, frequency management, fraud prevention, measurement and, where the visitor has provided any consent required by applicable law, advertising personalisation.

Your choices

Where required by applicable law, non-essential technologies will not be activated until the necessary choice or consent has been obtained. Visitors should be able to manage applicable preferences through the website’s consent controls.

You can also use your browser settings to restrict, block or delete cookies. Blocking some technologies may affect website functionality.

A separate Cookie Policy or cookie preference interface may provide additional information about the specific technologies currently used, their providers, purposes and durations.

10. Analytics and Measurement

Calculation Portal may use privacy-conscious website measurement and analytics technologies to understand aggregate website usage, diagnose problems and improve content and tools.

If Google Analytics, Google Tag Manager or another third-party analytics platform is implemented, this policy and the website’s consent controls will be updated as appropriate to identify the relevant provider and explain the applicable processing.

Where consent is legally required for analytics technologies, those technologies will be configured to respect the visitor’s applicable consent choice.

11. Advertising

Calculation Portal may display advertising to help fund the operation, maintenance and development of the website.

Advertising providers may process technical information and use cookies or similar technologies for purposes including advertisement delivery, security, fraud detection, frequency management, reporting and measurement. Personalised advertising may involve additional processing.

Where applicable law requires consent before advertising technologies or personalised advertising can be used, Calculation Portal will seek the required choice through an appropriate consent mechanism.

If Google advertising services or another advertising network is deployed, this section and our cookie disclosures should be updated to identify the provider and link to relevant privacy information and controls.

Calculation Portal does not control the independent processing activities of third parties acting as separate controllers. Their own privacy notices govern such processing.

12. Affiliate Links

Some pages on Calculation Portal may contain affiliate links. If you follow an affiliate link and subsequently make a purchase or complete another qualifying action, Calculation Portal may receive a commission.

Affiliate networks or merchants may use cookies, referral identifiers or similar technologies to attribute a transaction or action to a referring website.

The relevant merchant or affiliate provider may independently process information under its own privacy policy.

For more information about our commercial relationships, please see our Affiliate Disclosure.

13. Service Providers and Third Parties

We may use third-party service providers where reasonably necessary to operate and maintain Calculation Portal. Depending on the production configuration, these may include providers of:

• website hosting and infrastructure;
• content delivery and caching;
• domain name and DNS services;
• website security and anti-abuse systems;
• backup and disaster recovery services;
• email or contact-form delivery;
• spam prevention;
• analytics and performance measurement;
• consent management;
• advertising;
• affiliate tracking; and
• professional, legal or compliance services.

Where a provider processes personal information on our behalf, we seek to use providers appropriate to the processing involved and put appropriate contractual or organisational measures in place where required.

Some providers may instead act as independent controllers for some processing. In those circumstances, their own privacy terms apply to their independent processing.

14. When Information May Be Disclosed

Personal information may be disclosed where reasonably necessary:

• to service providers supporting website operations;
• to investigate security incidents, fraud or abuse;
• to comply with applicable law, regulation or legal process;
• to respond to a lawful request from a competent authority;
• to establish, exercise or defend legal rights;
• to protect the rights, safety or property of Calculation Portal or others;
• in connection with a legitimate business reorganisation, transfer or sale, subject to applicable law; or
• where you have directed or consented to the disclosure.

Calculation Portal does not disclose personal information merely because another private party requests it. Any disclosure will be assessed against applicable legal and contractual requirements.

15. International Data Transfers

The internet and many website service providers operate internationally. Consequently, personal information may in some circumstances be processed in a country other than the country in which you are located.

Where UK or European data protection law applies and personal data is transferred internationally, we will use an applicable lawful transfer mechanism or safeguard where one is required. Depending on the circumstances, this may include an adequacy regulation or decision, approved contractual safeguards, or another mechanism recognised by applicable data protection law.

16. Data Retention

We aim to retain personal information only for as long as reasonably necessary for the purpose for which it was collected, including applicable operational, security, legal, accounting and dispute-resolution requirements.

Retention periods may depend on factors including:

• the nature and sensitivity of the information;
• why the information was collected;
• whether it remains necessary for the relevant purpose;
• security and fraud-prevention requirements;
• applicable limitation periods;
• legal or regulatory obligations; and
• whether the information can instead be deleted or anonymised.

Contact correspondence may be retained for a reasonable period necessary to resolve the enquiry and maintain appropriate records.

Server, security and diagnostic records may be retained for periods appropriate to their operational and security purposes.

Consent records may be retained where necessary to demonstrate privacy choices or compliance.

17. Security

We use reasonable technical and organisational measures intended to protect information and the operation of Calculation Portal.

Measures may include, as appropriate:

• HTTPS encryption for data transmitted between browsers and the website;
• access controls;
• software and security updates;
• website and server security measures;
• backups;
• monitoring for malicious or abnormal activity; and
• limiting administrative access where reasonably practicable.

No website, network, transmission method or storage system can be guaranteed to be completely secure. We therefore cannot promise absolute security.

18. Your Privacy Rights

Privacy rights vary according to your location and the law applicable to the processing. Depending on the circumstances, you may have rights to:

• request information about how your personal data is processed;
• request access to personal data held about you;
• request correction of inaccurate or incomplete personal data;
• request deletion of personal data in certain circumstances;
• request restriction of processing in certain circumstances;
• object to certain processing;
• receive certain personal data in a portable format;
• withdraw consent where processing relies on consent;
• object to or opt out of certain direct marketing;
• make a complaint to an applicable data protection authority; and
• exercise other rights provided by applicable privacy legislation.

These rights are not absolute. Exceptions may apply depending on the applicable law, the information involved and the reason it is being processed.

We may need to verify your identity before responding to certain privacy requests. We will not request more information than reasonably necessary for verification.

19. UK and EEA Privacy Rights

If UK GDPR or European data protection law applies to the processing of your personal data, you may have rights including access, rectification, erasure, restriction, objection and data portability, subject to the conditions and exceptions contained in applicable law.

Where we rely on consent, you may withdraw your consent at any time in relation to future processing based on that consent.

Where we rely on legitimate interests, you may have a right to object to processing based on circumstances particular to you.

Complaints in the United Kingdom

If you are in the United Kingdom and believe that your personal information has been handled improperly, you may have the right to complain to the Information Commissioner’s Office (ICO).

We encourage you to contact us first so that we have an opportunity to investigate and address your concern, although doing so does not remove your right to contact the relevant supervisory authority.

20. California and Other US Privacy Rights

Residents of certain US states may have additional privacy rights if the relevant privacy legislation applies to Calculation Portal and the processing concerned.

Depending on applicable law, these may include rights to request access to or disclosure of certain personal information, correction, deletion, data portability, and to opt out of certain forms of sale, sharing, targeted advertising or profiling.

Calculation Portal will honour rights that apply to it under relevant legislation. The existence and scope of a particular right may depend on factors such as your state of residence, the nature of the processing and whether the relevant statutory thresholds and exemptions apply.

We will not unlawfully discriminate against an individual for exercising an applicable privacy right.

21. Children’s Privacy

Calculation Portal is a general-audience calculation and reference website. It is not designed as a service specifically directed at young children, and we do not knowingly seek to collect personal information from children through account registration.

Parents and guardians should supervise children’s use of online services where appropriate. If you believe that a child has submitted personal information to us in circumstances where it should not have been collected, please contact us so that we can review the matter.

22. External Websites and Services

Calculation Portal may link to external websites for sources, references, products, services, further reading or other useful information.

Following an external link takes you to a service that may be operated by another organisation. Calculation Portal does not control that organisation’s independent privacy practices.

You should review the privacy information provided by the external service before providing it with personal information.

23. Automated Decision-Making

Calculation Portal’s calculators automatically apply formulas, rules, assumptions or algorithms to values entered by users in order to generate requested outputs.

Producing a mathematical or informational calculator result is not intended to constitute a decision made by Calculation Portal about an individual that produces legal or similarly significant effects.

Calculator outputs are provided as informational tools. Users remain responsible for deciding how to use the results and should obtain appropriately qualified professional advice where a decision involves significant financial, medical, legal, engineering, safety or other consequences.

24. Browser Privacy Signals and Preference Controls

Browsers and devices may provide privacy settings or signals intended to communicate a user’s preferences regarding tracking or certain uses of personal information.

The legal effect of these signals varies between jurisdictions. Where Calculation Portal is legally required to recognise a particular browser-based opt-out preference signal, we will seek to process that signal as required by applicable law.

Cookie and consent preferences made through the website should be used as the primary mechanism for managing technologies covered by those controls.

25. Changes to This Privacy Policy

We may update this Privacy Policy when our website, technologies, service providers, legal obligations or data-processing practices change.

The current version will be published on this page and the Last updated date at the top of the policy will be revised.

Where a change materially affects how personal information is processed, additional notice will be provided where required by applicable law.

We recommend reviewing this page periodically if you use Calculation Portal regularly.

26. How to Contact Us

If you have a question about this Privacy Policy, want to exercise an applicable privacy right, or have a concern about the way personal information is handled, please contact Calculation Portal.
