Privacy
Below is a plain account of the data that is, and is not, collected when you use Unit Converter at converter-unit.com. The policy applies to the whole of converter-unit.com, not only to the unit converter.
Summary
- No registration, logins or passwords.
- Your inputs are processed on your device, not on our server.
- Cookies come from our analytics services and from advertising networks.
- Privacy requests are answered by email at [email protected].
Who we are
converter-unit.com is the home of Unit Converter, a free unit converter that works in your web browser. Questions about personal data go to the site's operator, who reads the mailbox [email protected]. The operator is the “controller” of that data in the sense used by the GDPR.
What information is collected
There are no user accounts on converter-unit.com, so we never ask for your name, a password or payment details. The tool does its work locally, on your device, and its inputs and results are not uploaded to converter-unit.com. Below we list the technical data that is collected through server logs, analytics and advertising, and why.
About cookies
Like most websites, converter-unit.com involves cookies and similar technologies, small pieces of data your browser keeps for a site. Our own pages do not set cookies. Cookies on converter-unit.com come from analytics and advertising providers. If you block cookies, the site still works; you may simply see less relevant ads.
Analytics and session recordings
Use of converter-unit.com is measured with Yandex Metrica and Microsoft Clarity. Typical data points are the pages you open, the time spent on them, where you came from, your browser and device, and a rough location. We also use their session replay and heatmap features, which show clicks, scrolling and pointer movement, to see which parts of the unit converter are hard to use. They set their own cookies, and Yandex and Microsoft handle the data under their own privacy statements. Our interest is in patterns across visits, not in identifying any particular person.
Web server logs
Our web server automatically records each request in standard log files. Each log line records the IP address, browser user agent, time and requested page. We use them to keep the site secure, diagnose errors and produce basic traffic statistics.
Advertising
Unit Converter is free because it shows ads. The networks that deliver ads may place cookies or use device information so that they can select ads, limit repeats and report on how ads perform. Where permitted, networks may personalise ads using your browsing on other sites as well as this one.
Your tool inputs are never shared with ad networks, which process their own data under their own privacy terms. You can opt out of personalised ads from many networks at optout.aboutads.info and youronlinechoices.eu, and you can block third-party cookies in your browser.
Legal bases for processing (EEA and UK)
If you are in the European Economic Area or the United Kingdom, we rely on the following legal bases:
- Consent where the law requires it for analytics and advertising technologies.
- Legitimate interests in running a secure, working, ad-funded website, weighed against your rights.
- Handling your messages: when you email us, we use your message to answer it.
Retention
Information is kept only while it serves its purpose; server logs are rotated out after a limited period unless they are needed to investigate misuse. Analytics and advertising providers keep data according to their own retention schedules. Correspondence is kept while it is needed to answer you and handle any follow-up.
Where data is processed
Our hosting, analytics and advertising providers may handle data outside the country where you live. Data protection rules in those countries may not be the same as in yours.
Your rights
If European or UK data protection law applies to you, you may access, rectify and erase your data, restrict or object to processing, and receive it in a portable form. You may withdraw consent at any time, without affecting processing that took place before.
Because we hold very little data and no accounts, we may need details such as your IP address and the approximate time of your visit to find anything relating to you. You also have the right to lodge a complaint with a data protection supervisory authority, in particular where you live or work. Requests can be sent to [email protected].
California privacy rights
If you are a California resident, the CCPA, as amended by the CPRA, gives you the right to know what personal information is collected about you, to request its deletion or correction, and to opt out of the sale or sharing of your personal information. We do not sell personal information in the everyday meaning of the word; no list of visitors is ever traded. Advertising cookies, though, can amount to “sharing” for cross-context behavioural advertising as California law defines it.
You can opt out by turning on the Global Privacy Control signal in your browser, blocking third-party cookies, or contacting us. You will not be discriminated against for exercising any of them.
Security
All pages on converter-unit.com are delivered over an encrypted HTTPS connection. Access to the server and its logs is limited to the people who run the site. No method is completely secure, but what you enter into the unit converter never reaches our server.
Children
Unit Converter is a general-audience site and is not directed to children under 13, or under 16 in the EEA and the UK. We do not knowingly collect data from children. Parents or guardians who think a child has contacted us can ask us to delete that information.
Changes to this policy
We update this page when our practices change, such as when a new service is added. The version published here is always the current one.
