Who to contact
This policy covers calculatorssite.com, published under the name Calculators Site. The website operator is responsible for deciding how information collected through the site is used.
For a privacy question or request, use our contact form and select “Privacy or personal information”. Include the page or feature concerned and the request you want us to consider. Do not send identity documents or sensitive information unless we have agreed a suitable way to provide them.
Calculator entries and saved preferences
The calculator interface processes the values you enter in your browser. It does not send those entries to us as a calculation request, save a personal calculation history on our servers, or include them in our measurement events. A page’s initial example result is supplied with the page; it is not a result based on your personal information.
Some tools remember your selected currency in your browser’s local storage. This preference is separate from the amounts or other values you enter. Entries normally disappear when you reload or leave a calculator; browser features such as restoring a tab may retain what was on screen.
If you copy, print or send a result yourself, the resulting document or message is outside this site’s storage. Avoid putting private details in a page address, contact message or public social-media comment.
Information the site receives
- Contact messages: your name, email address, selected topic and message, plus the delivery information needed to send and reply to it. You choose whether to provide these details.
- Hosting and security data: a request for a page necessarily reaches our hosting provider. Technical records can include an IP address, requested address, time, browser information and error or security events.
- Optional measurement: when you allow it, Cloudflare Web Analytics measures page use and loading performance. Reports can include the page, referral source, approximate country, browser/device category and page-speed measurements. Cloudflare’s measurement script reports page addresses without their query strings or fragments.
Optional measurement is off until you allow it on the cookie and choices page. We do not ask for payment information or provide user accounts on this version of the website.
Why we use this information
We use contact information to answer questions, investigate reported mistakes, handle privacy requests and deal with relevant business enquiries. Technical records help deliver pages, diagnose problems and protect the service against misuse. Optional measurement helps us understand which pages are useful and where loading or interaction needs improvement.
Where a law requires a lawful basis, these purposes may involve our legitimate interests in operating a secure website and responding to enquiries, consent for optional measurement, or compliance with a legal obligation. The applicable basis depends on the activity and the law that applies. Sending a message does not subscribe you to a mailing list.
Service providers and other disclosures
Cloudflare provides the website’s hosting, security and the optional measurement service. Cloudflare Web Analytics is designed without cookies, local storage or cross-site visitor profiles. Hosting and security processing are distinct from those measurement reports. Read Cloudflare’s privacy policy and its Web Analytics information.
Contact submissions are delivered through Resend to the site’s receiving mailbox. Resend and the relevant email provider process the contents and delivery data to provide that service. See Resend’s privacy policy. Do not use the form to send medical records, bank details or passwords.
The contact form uses Cloudflare Turnstile to check that a message comes from a person rather than an automated script. Turnstile processes browser and network signals, such as your IP address, when the form loads and when you send it. It is part of the form’s security, not optional measurement, and sending a message is not possible without it. See Cloudflare’s Turnstile privacy addendum.
Information may also be disclosed when reasonably necessary to comply with the law, respond to a valid legal request, or protect people and the service. We do not sell contact messages or calculator entries. External links and social profiles have their own privacy practices once you follow them.
Advertising and Google services
Google AdSense advertising is not enabled on this version of the site. We do not currently load Google advertising tags or use your calculator entries for ad targeting.
If we introduce Google advertising, Google and other participating advertising vendors may use cookies, web beacons, IP addresses or similar identifiers to deliver, measure and, where permitted, personalise ads using visits to this and other websites. We will update these disclosures and identify the advertising partners and controls before enabling that processing.
For Google’s explanation, read how Google uses information from partner sites. Google account advertising preferences can be managed in My Ad Center. These external settings do not replace any consent choice required on this website.
How long information is kept
Calculator entries are not retained as a server-side history. Saved currency and measurement choices remain in that browser until you change the choice or clear the site’s data; local storage has no automatic expiry in this implementation.
Contact correspondence is kept for handling the enquiry and any related follow-up, correction, complaint or legal obligation. The relevant criteria are whether the issue remains open, whether the record is still needed to explain an action, and whether retention is required for a legal claim or obligation. There is no single fixed period for every kind of message.
Hosting, security, delivery and measurement records also follow the relevant provider’s retention settings and policies. We do not promise an immediate purge of provider logs or backups when a message is deleted.
Security and international processing
We use encrypted HTTPS connections in production and restrict the use of submitted information to the purposes described here. No website, browser or email service can guarantee absolute security.
Service providers may process information in countries other than where you live. Where data-transfer rules apply, the appropriate safeguards and provider arrangements must apply to that processing. You can ask us about the providers and safeguards relevant to your request through the contact page.
Your choices and privacy rights
You can use the calculators without allowing optional measurement. You can change or withdraw that permission on Cookies & choices, and remove local preferences using your browser’s site-data controls.
Depending on the law that applies and the information involved, you may have rights to access, correct or delete personal information, restrict processing, obtain a portable copy, or object to processing. Where consent is the basis, you may withdraw it without changing the lawfulness of earlier processing. Rights can be subject to exceptions, including legal retention requirements.
Right to object: where processing relies on legitimate interests and the applicable law provides this right, you can object on grounds relating to your situation. Explain the processing concerned in your request so we can assess it.
We may ask for proportionate information to verify a request. We cannot retrieve a server-side calculation history that we do not hold. You may also complain to the relevant data-protection authority, including the UK Information Commissioner where applicable.
Children and policy updates
Educational calculators can be read without providing personal details. This site is not designed to collect personal information from children. A parent or guardian who believes a child has sent us personal information can contact us to request a review and appropriate deletion.
We will revise this policy when the site’s data practices change. The date above identifies the latest revision. Read the cookie policy for storage details and the terms and conditions for limits on using calculator results.
