The short version
The cipher tools work in your browser, so the text you type there is not sent to us. We collect data through the contact form and through cookies, and we use Google services for statistics, ads and spam protection.
Text you enter in the tools
The Caesar cipher tool and the other cipher tools process your text in your browser. It is not sent to our server. The exception is the API and its test console: a request sent there reaches our server, because that is how the API works.
The contact form
When you use the contact form, your name, email address and message are sent to the site operator by email. We use them only to answer you and keep the message as long as we need it for that. We do not use your address for marketing.
The form uses Google reCAPTCHA to stop spam, which sends data about your device and how you use the page to Google.
Google services
On the live site we use Google Analytics to count visits and see which pages are read, and Google AdSense to show ads, which may be personalised depending on your settings. Google processes this data under its own privacy policy. It also explains how it uses data from sites like this one and which cookies it uses.
Server logs
Like most websites, our server can record technical details of each request, such as the IP address, the page requested and the browser type. They help keep the site working and secure.
Your choices
You can block or delete cookies in your browser settings, though some features may stop working. You can manage personalised ads in My Ad Center and turn off Analytics with Google’s opt-out add-on.
Your rights
If you are in the European Union or a country with similar law, you can ask for access to your personal data, and ask us to correct or delete it, restrict its use or stop using it. You can also complain to your data protection authority. To use these rights, write to us through the contact form.
Changes to this policy
If the way we handle data changes, we will update this page and the date at the top.
