Privacy policy
Short version: we don't collect anything about you. Last updated 6 November 2026.
What we don't do
- No accounts or logins. There is nothing to sign up for.
- No cookies.
- No analytics, tracking pixels, advertising or third-party scripts.
- No request logs. We don't record your IP address, device or the pages you visit.
- No third-party fonts or embeds. Everything the page loads comes from hypb.app.
What stays on your device
The calculator keeps a few things in your browser so it is quick and works offline. None of it is ever sent to us.
hypb:last: your last plan, so the calculator opens where you left it.hypb:theme: your light or dark mode choice, if you picked one.- A saved copy of the site's pages, scripts and fonts, so the calculator works with no signal at the venue.
You can remove them at any time by clearing this site's data in your browser settings.
Plan links
When you copy a plan link, your splits are stored in the part of the address after the #. Browsers do not send that part to the server, so a shared plan never reaches us. Anyone you send the link to can see the splits in it.
Hosting
hyPB is served by Cloudflare. As with any website, your browser's request passes through Cloudflare's network so the page can be delivered and protected against abuse, which means Cloudflare briefly handles technical details such as your IP address. We have switched off request logging for this site and do not receive or store those details. Cloudflare's own handling is described in the Cloudflare privacy policy.
If you email us
Mail to support@hypb.app is forwarded to our inbox by Cloudflare Email Routing. We use your address and message only to reply, and we delete the conversation if you ask.
Your rights
Because we hold no personal data from using the site, there is nothing to access, correct or export. If you have emailed us, you can ask for a copy of that correspondence or for it to be deleted, and you can complain to your local data protection authority if you think we have handled your data wrongly.
Changes
If this policy changes, the new version will be posted here with a new date. We will not start collecting personal data without saying so on this page first.
