What HolidayMaximizer collects

You do not need an account to use the site. Planner choices are processed in your browser. Some selections may appear in the page URL, and standard request information such as IP address, browser details, requested URL and timestamps may be processed in hosting or security logs.

Hosting and holiday-data services

The site is hosted through Cloudflare. Cloudflare may process technical request and security information to deliver and protect the site. For countries where we do not use a locally bundled calendar, your browser may request public-holiday data from Nager.Holidays; that service can receive the technical information normally sent with a web request, including your IP address and the country/year requested.

Advertising, referrals and cookies

To keep HolidayMaximizer free without requiring accounts or subscriptions, selected pages display banner advertisements provided by our advertising partner, Adsterra (Domain ID 6176073). We do not use popunders, disguised social bars or adult advertisements. After dates are calculated, results may also include clearly disclosed travel comparison links.

For visitors in the European Economic Area (EEA) and the United Kingdom, non-essential advertising scripts are not loaded unless you grant consent via the privacy banner. You can change or withdraw your choice at any time using the Cookie preferences link in the site footer. Downloaded holiday calendars and aggregate non-personal usage counts may be stored in browser local storage purely to support the calculator and measure feature reliability without transmitting personal leave dates.

Why data may be processed

Technical data may be processed where necessary to provide, secure and maintain the site. Non-essential advertising storage or personalised advertising is based on consent where applicable.

Your rights

Depending on your location, you may have rights relating to access, correction, deletion, restriction, objection or withdrawal of consent. For privacy questions or requests, email contact@kattegatstudio.dk.

Third-party information

Adsterra, Cloudflare and Nager.Holidays publish their own privacy policies for technical or advertising data they process as independent service providers.
