Your measurement choice
Vercel Web Analytics and Speed Insights are optional here. They stay off until you allow measurement. You can withdraw permission below at any time. A change applies to this browser, not to your other devices or browsers.
Optional measurement: off. It stays off unless you choose to allow it.
Allow anonymous usage and page-speed measurement, or keep it off. Calculators work either way. Saving a choice reloads this page.
The same controls are available through “Cookies & choices” in the footer. They control Vercel measurement only; they do not grant permission for Google advertising. Basic page delivery and security processing still happen when optional measurement is off.
Cookies and local storage explained
A cookie is a small piece of data a website can ask your browser to store and send with later requests. Local storage is a separate browser store that is not automatically sent with every request. Both can remember choices, so a policy needs to explain more than cookies alone.
On this version of Calculators Site, the application saves only the preferences described below. Calculator entries are held in the current page’s memory rather than a saved calculation history.
Preferences saved by this site
- Currency preference —
currency: local storage used by calculators with a currency selector. It remembers the currency you choose, not your entered amounts. It is saved when you choose a currency and stays until you change it or clear the site’s data. - Measurement choice —
calculators-site:measurement:v1: local storage recording “allowed” or “denied” when you use the controls above. It contains no name, email address or calculator values. It stays until you change it or clear the site’s data.
These records have no automatic expiry. If the saved choice cannot be read or is unrecognised, measurement is off. If your browser blocks saving a withdrawal, measurement stops for the current page and a message explains how to clear an earlier permission before reloading. Currency selection can still work for the current visit even when the preference cannot be saved.
What optional measurement does
When allowed, Vercel Web Analytics measures page use, and Speed Insights measures loading and interaction performance. Data can include a page address, referral source, approximate country, browser/device category and performance timings. These services are designed without advertising cookies and do not provide us with an individual’s browsing history across other websites.
Our integration removes query strings and fragments from the page URLs it sends. It does not send calculator field values or contact message text as custom events. Saving a withdrawal reloads this page so previously loaded measurement scripts are removed from the new document. It does not erase data that was already collected.
Read Vercel’s Web Analytics privacy information and Speed Insights privacy information for its data practices. Our privacy policy also explains hosting, email and retention.
Advertising and third-party services
Google AdSense is not enabled on the current site, and there are no Google advertising cookies set by an AdSense integration here. A link to YouTube, Instagram, Facebook or an external source is not an embedded advertising widget; that service’s own policy applies when you visit it.
If advertising is added, Google and participating vendors may use cookies or similar technologies to show and measure ads, including personalised ads where permitted. The relevant vendors, purposes and consent choices will need to be disclosed before that processing is enabled. This page’s Vercel preference is not advertising consent.
You can read Google’s explanation of data use on partner sites and manage Google account ad preferences in My Ad Center. Those settings do not turn off every website’s storage.
Clear or block browser storage
Your browser’s privacy or site-settings menu can remove this website’s cookies and site data, including local storage. Clearing the site’s data removes the saved currency and measurement choice; measurement then returns to its default off state. Blocking storage may stop preferences being remembered, but should not require you to allow optional measurement to use a calculator.
Private-browsing modes and content blockers may apply additional restrictions. Changes here do not remove messages you have already submitted through the contact form or records held by providers.
Updates and questions
We will update this page when we change the storage or measurement technologies used on the site. Its revision date appears above. For a question, contact us using the privacy topic.
