Privacy
We collect nothing about you. There are no accounts, no analytics, no tracking pixels and no advertising cookies. That is not a policy we intend to hold to, it is a description of how the site is built, and the rest of this page is the detail behind it.

The calculator never sends anything
Every figure you type stays in your browser. The maths runs on your device and there is no server to send it to: every page here is static HTML, built in advance.
No accounts, no mailing list
There is nothing to sign up for and no form that submits anywhere, so there is no name, address or payment detail for us to hold.
No analytics of any kind
We do not run Google Analytics or any alternative, and we set no cookies. We cannot tell you how many people read this page, because we do not know.
What is stored on your device
One entry, in your browser's local storage, called obj-theme. It remembers whether you chose light or dark, and it is never transmitted anywhere.
Clearing this site's data removes it, and the site works normally without it.
Who else sees your visit
Two, and neither is a tracker. The typefaces are served from this domain, so no third party is contacted in order to render a page.
- Cloudflare serves this site. Like any host, it processes your IP address and request in order to deliver the page, under its own privacy terms.
- Sites we link to. Follow a link to a cruise line or a booking site and you are on their property, under their policies. We have no visibility into what happens there.
If you email us
Mail to hello@openbookjourneys.com is forwarded by Cloudflare
Email Routing into a Google mailbox. Anything you write to us therefore sits with those two
companies as well as with us. We use it to reply to you and for nothing else.
Your rights
Rules such as the GDPR and the CCPA give you the right to see, correct or delete the personal data a site holds about you, and to object to it being sold. We hold none and we sell nothing, so in practice there is nothing to request. If you want that confirmed in writing, ask and we will confirm it.
Money
Commercial relationships are listed in full, including what they pay, on the disclosure page. Where we ever carry a paid link it is marked as one, next to the link.
Changes, and how to reach us
If this policy changes, the date at the top changes with it. Questions to hello@openbookjourneys.com.
