Privacy Policy

Last Updated: May 15, 2026

This Privacy Policy explains what information CaesarCipher.org ("we," "our," "us") collects when you visit our site, how we use it, and the choices you have. CaesarCipher.org provides browser-based cipher tools, calculators, converters, and educational articles. We do not require an account, do not sell goods or subscriptions, and do not run a newsletter.

1. Information We Collect

Tool Inputs

The text, numbers, and other values you type into our cipher, calculator, and converter tools are processed locally in your browser wherever technically possible. These inputs are not transmitted to our servers.

Contact Information

If you email us at the address below, we receive your email address and the contents of your message.

Log Data

Our hosting and content-delivery providers automatically record standard server log information when your browser requests a page. This may include your IP address, user agent, the page requested, the referring URL, and a timestamp. We use this data to operate the site, detect abuse, and troubleshoot errors.

Analytics

We use privacy-respecting analytics (such as Google Tag Manager–loaded Google Analytics and Microsoft Clarity) to understand aggregate site usage. These tools may set cookies and record interactions such as clicks and page views.

Advertising

We display advertising provided by Google AdSense and other third-party vendors on some pages. See Section 4 for the full disclosure required by Google.

We do not ask you to register an account, we do not sell products or subscriptions, and we do not send newsletters or marketing emails.

2. How We Use Information

We use the information described above to:

Operate, maintain, and improve the site
Respond to questions, bug reports, and feedback sent by email
Measure aggregate usage and identify which tools are most helpful
Display relevant advertising via Google AdSense and other partners
Detect and prevent abuse, fraud, and security incidents
Comply with legal obligations

3. Cookies and Similar Technologies

We and our service providers use cookies, web beacons, and similar technologies for the following purposes:

Essential: Remembering site preferences such as language.
Analytics: Counting visits, measuring traffic sources, and understanding which pages and tools are used.
Advertising: Showing ads from Google AdSense and other partners, measuring ad performance, and limiting how often you see the same ad.

Most browsers let you block or delete cookies through their settings. Blocking cookies may break certain features and will not stop ads from being shown — it will only stop them from being personalized.

In compliance with Google Publisher Policies, we provide the following disclosures:

Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites.
Google's use of advertising cookies enables it and its partners to serve ads to our users based on their visit to our site and other sites on the Internet.
Users may opt out of personalized advertising by visiting Google Ads Settings.
Users may also opt out of third-party vendor use of cookies for personalized advertising by visiting www.aboutads.info.
Third-party advertising partners may place or read cookies on your browser, or use web beacons, IP addresses, and similar technologies to collect information for ad delivery, measurement, and reporting.

If you are in the European Economic Area, United Kingdom, or Switzerland, we will request your consent before any non-essential cookies — including advertising cookies — are set on your device.

We share information only with:

Service providers that help us operate the site (hosting, content delivery, analytics, advertising).
Law enforcement or other parties when required by law, valid legal process, or to protect rights, property, or safety.

We do not sell or rent your personal information.

6. Data Retention

We retain log and analytics data only as long as needed for the purposes described above, then delete or aggregate it. Email correspondence is retained for as long as needed to address your inquiry.

7. International Data Transfers

CaesarCipher.org uses global content-delivery and analytics providers. Your information may be processed in countries other than your own, including the United States. By using the site you understand and consent to such transfers.

8. Your Rights

Depending on your jurisdiction, you may have rights to access, correct, delete, or restrict the use of your personal information, and to opt out of personalized advertising. To exercise these rights, please email us using the contact details below.

9. Children's Privacy

CaesarCipher.org is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will take steps to delete it.
