Privacy policy

Last updated: October 16, 2026

This website (opendayapi.com) is published by JB Studio to describe OpenDay API and to show free holiday and business-day lookups. We collect as little as possible.

What we do not do

No tracking cookies, no analytics scripts, no advertising scripts and no third-party trackers.
No accounts, logins or forms that collect personal data.
The lookup tools and the business days calculator run entirely in your browser. The dates you enter are never sent to us or anyone else.
Fonts and images are served from this website; the pages load no outside scripts.

Hosting

The site is hosted on Cloudflare Pages. Like any web host, Cloudflare processes technical data needed to deliver pages and protect the site (for example IP addresses and request logs). See Cloudflare's privacy policy for details.

The API and payments

OpenDay API is sold through Apify. When you sign up, call the API or pay, Apify's terms and privacy policy apply. This website does not handle payments.
