Privacy Policy — browser extensions
Last updated: 19 July 2026. Applies to calendana's browser extensions for Chrome and Firefox: “Name Day Today” and “Public Holidays & Long Weekends”.
What the extensions do
Name Day Today replaces your new tab page with the name day(s) celebrated today and on the coming days, for Greek (εορτολόγιο), Polish (imieniny) and Swedish (namnsdag) naming traditions.
Public Holidays & Long Weekends uses a toolbar popup and badge to show the next public holiday, natural long weekends, leave-aware bridge-day plans and a mini month calendar for Germany, Spain, France, Italy and Brazil. Germany users can select a Bundesland for statewide regional holidays. Municipal exceptions are not assumed to apply statewide, and Brazilian optional federal observances are not treated as guaranteed national days off.
All name-day and public-holiday data is bundled inside the extensions and read locally. No network request is needed to display it.
Data stored on your device
- Name-day tradition preference (Greek / Polish / Swedish): saved locally so the new tab opens in the tradition you chose.
- Holiday country/language preference (Germany / Spain / France / Italy / Brazil): saved locally so the popup displays the calendar you chose.
- German Bundesland preference (optional): saved locally so regional public holidays can be included.
These preferences stay on your device and are never transmitted.
Data we collect or transmit
None. The extensions contain no analytics, no advertising, no trackers, no cookies, and make no network requests of their own. We receive nothing.
Links to calendana.com
The extensions contain links you can choose to click (for example, “open the full calendar”). Following a link opens calendana.com in your browser as a normal visit. Those links carry a utm_source parameter so that, if you choose to visit, our website analytics can attribute the visit to the extension. This happens only when you click, is standard web link attribution, and involves no data stored or sent by the extension itself. Use of calendana.com is governed by the website's own terms.
Permissions
