Before you publish this: have a solicitor or a privacy-compliance service review it against your actual setup and jurisdiction. It describes the site as built, but it is a starting document and not legal advice.
This policy explains how Calculate Conversion handles information when you use this site. It applies to every page on this domain.
What we do not collect
The converters run entirely in your browser. The values and units you enter are processed in JavaScript on the page and are never transmitted anywhere. We do not store them and we cannot see them. Closing the tab discards them.
There are no user accounts, and we do not ask for or hold names, addresses or payment details.
What is collected
Server logs
Our hosting provider records standard technical information for each request: IP address, browser and device type, the page requested, the referring page and a timestamp. This keeps the site running and helps detect abuse. Logs are retained for a limited period and then deleted.
Analytics
We may use a privacy-focused analytics tool to count page views and see which converters are used. Where analytics is in place it records aggregate page-level data only, and is never linked to the values you type.
Advertising
This site carries advertising, which is what keeps it free. Ads are supplied by Google AdSense and its partners.
How advertising cookies work here
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and others on the internet.
- You can opt out of personalised advertising at Google Ads Settings.
- You can opt out of some third-party vendors' cookies at aboutads.info/choices or youronlinechoices.com.
- Google publishes the list of vendors it works with in its partner-sites policy.
Opting out does not remove advertising. It means the ads you see are less relevant to you.
Consent
If you are in the European Economic Area, the United Kingdom or Switzerland, you will be shown a consent notice before any advertising or analytics cookie is set, and you can accept, refuse or change your choices at any time through that notice. Refusing consent means you see non-personalised advertising instead.
California residents
We do not sell personal information for money. Some sharing of advertising identifiers may count as a "sale" or "share" under the CCPA as amended, and California residents can opt out through the consent notice or the vendor links above.
Your rights
Depending on where you live you may have the right to request access to personal data we hold about you, ask for it to be corrected or erased, object to or restrict processing, and withdraw cookie consent at any time.
Because we hold no accounts and no converter inputs, in practice the only data connected to you sits in server logs and in advertising cookies held by your own browser, which you can clear at any time in your browser settings. To make a request, email hello@calculateconversion.online.
Children
This site is not directed at children under 13 and we do not knowingly collect information from them.
External links
Some pages link to other websites. We are not responsible for their content or their privacy practices, and this policy does not cover them.
Changes
We may update this policy as the site changes. The date below reflects the current version.
