Cookies are small text files placed on your device when visiting a website. In addition to standard cookies, modern web applications utilize HTML5 LocalStorage to securely and efficiently save user preferences directly in your browser.
2. What Data Do We Store and Why?
On Date Calculator, data minimization is our priority. All date calculations run entirely client-side in your own web browser.
Strictly Necessary Storage: We utilize local browser storage (LocalStorage) to remember that you have accepted our cookie notice. This prevents the banner from reappearing on every page you visit.
No Third-Party Tracking Cookies: We do not use advertising network trackers or invasive third-party analytics cookies that monitor your browsing activity across other websites.
