At 13cal.net, we take your privacy seriously. This Privacy Policy explains how we collect, use, and protect information when you use our calendar visualization and date conversion tools.
The short version: We collect minimal data and do not sell or share your personal information.
Our Service does not require account creation or login. We do not collect names, email addresses, or other personal identifying information.
When you visit our website, we may automatically collect browser type and version, device type, general geographic location (country/region level only), pages visited and time spent, and referring website. This information is used only to understand how our Service is used and to improve user experience.
We use your browser's local storage to save your preferences, such as calendar view preferences, overlay settings, and theme preferences. This data is stored only on your device and is never transmitted to our servers.
We use collected information to provide and maintain the Service, understand usage patterns and improve features, monitor and analyze trends, and detect and prevent technical issues.
We do not sell, trade, or rent your personal information to third parties. We may share aggregated, non-personally identifiable information for analytical purposes. We may disclose information if required by law or to protect our rights, property, or safety.
We use minimal cookies necessary for the Service to function properly, including essential cookies required for basic site functionality and analytics cookies to help us understand how visitors use the site. You can configure your browser to refuse cookies, though this may affect some features.
We implement appropriate technical and organizational measures to protect the information we collect. However, no method of transmission over the Internet is 100% secure, and we cannot guarantee absolute security.
Depending on your location, you may have the right to access, correct, or delete your information. Since we collect minimal data and store preferences locally on your device, you can exercise most of these rights by clearing your browser's local storage and cookies.
We may update this Privacy Policy from time to time. We will notify you of any changes by updating the "Last updated" date.
