What the hippo browser extension stores, what it sends, and where it goes.
The short version. hippo has no servers of ours. The extension talks only to the hippo server address you enter yourself, and to nothing else. Nothing is sold, shared, or sent to any third party, and there is no analytics or tracking of any kind.
What it keeps on your machine
- The address of your own hippo server.
- A device token, issued by your own server when you approve this browser from your dashboard.
- A copy of the most recent schedule, so the extension keeps working when the network does not.
- A randomly generated id for this browser, so your server can tell your devices apart.
All of it lives in the browser's own extension storage and never leaves your machine except as described below.
What it sends to your server
- A request for the current schedule, a few times a minute.
- When you ask for more time, that request.
- If you have set a usage allowance, the number of seconds spent on a site covered by that allowance — a count, never a URL, page, or anything you typed or read.
What it never does
- It does not collect, store, or transmit your browsing history.
- It does not read page content, form fields, passwords, or anything you type.
- It does not use cookies, analytics, advertising, or fingerprinting.
- It does not send anything to the extension's author or to any third party.
Why it can see every page
The extension runs on all sites because a bedtime that only covered a list of sites written in advance would be trivial to walk around. On each page it checks one thing — the site's hostname, compared against your own lists — and acts on that alone. The rest of the page is never read and never leaves the tab.
Deleting your data
Removing the extension deletes everything it stored in your browser. Anything your own hippo server holds is yours, on hardware you control, and you can delete it there.
