Privacy Policy
Holiday Hours is built on a simple principle: your calculations belong to you. The tools run in your browser and your inputs are never sent to us. This policy explains what that means, and how cookies, advertising and analytics work on the site.
Who we are
"Holiday Hours" (this site, holidayhours.co.uk) is the data controller for
the limited processing described below. You can reach us any time via our
contact page.
Your calculator inputs
We do not collect them. When you use a calculator, all computation happens inside your browser using JavaScript. Your inputs — employment type, hours, leave days, dates — are never transmitted to our servers.
Your browser's localStorage is used to save your session so you can
return to a partially completed calculation. This data never leaves your device, cannot be
read by other websites, and is never sent to a server. You can clear it any time via
"Start again" on a calculator, or by clearing site data for holidayhours.co.uk.
localStorage is not a cookie.
Cookies & similar technologies
Holiday Hours itself sets no tracking cookies. Cookies on this site come from two areas:
- Advertising (Google AdSense) — Google and its advertising partners may set and read cookies (and similar identifiers) to serve and measure ads. In the UK, EEA and Switzerland these are only used for personalised advertising if you give consent (see below).
- Strictly necessary — a small amount of local storage used to remember your light/dark theme preference and your consent choice. These are essential to how the site works and carry no tracking function.
Advertising
Holiday Hours is free to use. To cover the cost of building and hosting it, we display ads served by Google AdSense. As a third-party vendor, Google uses cookies and device identifiers to serve ads based on a user's prior visits to this and other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you. You can learn how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites.
- You can review and control the ads Google shows you, and opt out of personalised ads from Google, in your Google Ads settings.
- You can opt out of personalised advertising from many other vendors at aboutads.info/choices and youronlinechoices.eu.
We do not sell your personal data. Where you decline consent for personalised ads, Google may still show non-personalised ads, which use cookies only for frequency capping, aggregate reporting and fraud/abuse protection — not to build a profile of you.
Your consent choices (UK, EEA & Switzerland)
If you're visiting from the UK, the EEA or Switzerland, we present a consent management platform (CMP) — a Google-certified consent tool that works with the IAB Transparency & Consent Framework — before personalised advertising cookies are set. You can:
- Accept or reject personalised advertising and the associated cookies;
- review the advertising partners and purposes involved; and
- change your choice at any time by reopening the consent options from the "Privacy & ad settings" (or cookie) link shown on the site.
Analytics
We use Umami Analytics, a privacy-first, open-source platform, on our own self-hosted instance. Umami:
- Does not use cookies
- Does not collect personal identifiers (no IP address stored, no fingerprinting)
- Collects only aggregate page-view counts and referrer data
- Is not shared with Umami Inc. or any third party
We use this anonymous aggregate data only to understand which calculators are most useful and to prioritise improvements.
Shareable links
When you use a "Share Results" button, your calculator inputs are encoded into the URL as a compressed string. This contains only the numbers and selections you entered — no name, email, or identifying information. Sharing the link is entirely optional.
Third-party services
| Service | Purpose | Data involved |
|---|---|---|
| Google AdSense | Advertising (keeps the tools free) | Cookies/identifiers for ad serving & measurement; personalised only with consent. See Google's Privacy Policy. |
| Cloudflare (CDN & hosting) | Hosting & delivery | Standard web request logs (IP, user-agent), retained per Cloudflare policy, not accessible to us |
| Umami Analytics (self-hosted) | Anonymous page analytics | Page URL, referrer, browser type — no personal data, no cookies |
| Google Fonts / Fontshare | Typography | Font requests made by your browser — subject to their privacy policies |
Contacting us
If you send us a message via our contact form, we use the name, email address and message you provide solely to respond to your enquiry. We don't use it for marketing and we don't share it.
Your rights
We hold no calculator data and no user accounts, so there is generally nothing for us to access, correct or delete. For any personal data you send us via the contact form, and for data processed by our advertising partners, you have rights under UK GDPR — including access, correction, erasure and objection. To exercise them regarding data we hold, use our contact page. For ad-related data held by Google and its partners, use the ad controls linked in the Advertising section above. You also have the right to complain to the UK Information Commissioner's Office (ICO).
Children
This site is not directed at children under 13, and we do not knowingly collect any information from children. Consistent with advertising policies, we do not request personalised ads for anyone we know to be under the applicable age of consent.
Changes to this policy
If this policy changes materially, we will update the date below. Continuing to use the site after an update constitutes acceptance of the revised policy.
