4. Purposes and lawful bases
Responding to messages and investigating reports
Contact information and message content are used to respond, reproduce reported errors, maintain correspondence and improve the site. The usual lawful basis is legitimate interests: operating, maintaining and improving Units-Calc and responding to people who contact the site.
Operating and securing the website
Technical logs may be used to deliver pages, diagnose faults, prevent spam or abuse, protect the website and maintain service availability. The usual lawful basis is legitimate interests in running a secure and reliable website. Some processing may also be necessary to meet legal obligations.
Analytics
Where required, consent is used for optional analytics cookies or similar technologies. Analytics information helps understand which pages are used, identify technical problems and improve content.
Advertising
Where required, consent is used for advertising cookies, identifiers and associated processing. Advertising helps fund the website. Depending on your consent choices and location, ads may be personalised, non-personalised, contextual or limited.
Where processing relies on consent, you may withdraw that consent at any time. Withdrawal does not make earlier processing unlawful.
5. Calculator inputs
Calculator and converter inputs are generally processed in your browser to produce a result. Units-Calc does not intentionally create personal profiles or user accounts from the values entered into its calculators.
You should not enter information that directly identifies you or another person unless a calculator specifically requires it and the page clearly explains why. Health, financial and other calculator results are general estimates and should not be treated as personalised professional advice.
Analytics or advertising services may record page and interaction information when permitted, but Units-Calc should not configure them to deliberately capture free-text entries, passwords or complete form contents.
6. Google Analytics
Units-Calc may use Google Analytics 4 to understand how visitors use the site. Depending on configuration and consent, Google Analytics may process information such as pages viewed, approximate geographic location, device and browser information, referral source, session events and IP-derived information.
Google acts as a service provider for analytics data and may also process information under its own terms and policies. Analytics information may be combined into reports that help identify popular pages, usability problems and broad traffic patterns.
Event-level Analytics data controlled through the property’s standard retention setting is kept for no longer than 14 months. Aggregated reporting information may remain available for longer in accordance with Google Analytics functionality.
Analytics cookies or similar technologies should not be activated before valid consent where consent is legally required.
How Google uses information from partner sites7. Advertising and Google AdSense
Units-Calc may display advertisements supplied through Google AdSense and participating advertising technology providers. Advertising services may process information such as your IP address, browser or device information, the page visited, consent signals, advertising identifiers, ad impressions and interactions.
Google and its partners may use cookies or similar technologies to deliver and measure advertisements, prevent fraud, limit repeated ads and—where you have consented—personalise advertising based on activity or inferred interests.
Where consent is not provided, the type of advertising that can be shown may be restricted. Non-personalised or limited advertising can still involve some processing for delivery, security, fraud prevention, frequency control or measurement, subject to applicable law and platform configuration.
Advertising personalisation may involve profiling by Google or other advertising providers. Units-Calc does not itself make decisions that produce legal or similarly significant effects about visitors.
10. International transfers
Some service providers, including Google and infrastructure providers, may process information outside the United Kingdom. Countries outside the UK may have different data-protection laws.
Where the website operator is responsible for an international transfer, appropriate safeguards should be used as required by law. Service providers may rely on mechanisms such as adequacy regulations, approved contractual safeguards or other lawful transfer arrangements described in their documentation.
11. How long information is kept
- Contact messages: kept only while reasonably needed to respond, investigate an issue, maintain necessary correspondence or establish and defend legal rights. Routine messages should be reviewed periodically and deleted when no longer needed.
- Security and server logs: retained according to the hosting and security provider’s configured periods and only as long as reasonably necessary for security, diagnostics and abuse prevention.
- Google Analytics: event-level data is retained for no longer than 14 months under the standard property setting described above.
- Advertising and consent information: retained according to the consent platform, Google and advertising providers’ applicable settings and policies.
Information may be kept for longer where reasonably required by law, for dispute resolution, fraud prevention or the establishment, exercise or defence of legal claims.
12. Your data-protection rights

- Access
Ask for a copy of personal information held about you. - Rectification
Ask for inaccurate or incomplete information to be corrected. - Erasure
Ask for information to be deleted in certain circumstances. - Restriction
Ask for processing to be limited in certain circumstances. - Object

Raise a concern with the website operator or the ICO.
To make a request, use the contact form and select “Privacy or data rights request”. Reasonable information may be requested to confirm your identity and locate the relevant data.
You may also complain to the UK Information Commissioner’s Office. It is usually sensible to raise the concern with Units-Calc first so there is an opportunity to resolve it.
Make a complaint to the ICO13. Children’s information
Units-Calc is a general-audience calculator website and is not designed to knowingly collect personal information from children through accounts or profiles. Children should avoid submitting personal information through the contact form without appropriate adult guidance.
Some calculators may be unsuitable for children or may require age-specific interpretation. Individual calculator pages should explain relevant limitations.
14. Security
Reasonable technical and organisational measures should be used to protect information, including HTTPS, access controls, input validation, software updates, spam protection and limiting retention.
No internet transmission or storage system can be guaranteed completely secure. Visitors should not submit confidential or sensitive material that is unnecessary for the enquiry.
15. Changes to this policy
This policy may be updated when the site’s services, providers, legal obligations or data practices change. The “Last updated” date at the top will be changed when a substantive edit is published.
The date is deliberately written into the page and is not automatically replaced each time somebody visits.
16. Contact about privacy
For questions, rights requests or complaints about how personal information is handled, use the contact form and select “Privacy or data rights request”.

Publishing a privacy policy does not itself control cookies or make analytics and advertising compliant. Configure a suitable consent management platform so that non-essential technologies follow the visitor’s choices, and keep this policy aligned with the services and retention settings actually used.
