Nihil Novi is a Chrome extension that hides the posts you've already seen on the sites you turn it on for. It runs on your computer and sends nothing about you anywhere. This page says what it handles and where that goes.
What it stores, on your computer only
In Chrome's extension storage on your computer (chrome.storage.local), readable only by the
extension's own pages and service worker:
- The sites you turned it on for, where their feed is on the page, and their settings (how many times to show a post, a finite source, newest-first, the "only from" addresses you chose, a daily limit, notifications).
- For each site, a short fingerprint of each post you've seen: the first 16 hexadecimal characters of a SHA-256 hash of the post's link (or of its text when it has no link). Never the link or the text itself. With it, how many visits you've seen the post in and when. Fingerprints not seen for 90 days are deleted, and at most 5,000 are kept per site.
- Today's minutes, posts seen and pages opened on each site, for the daily limit you may set. They start again from zero every day.
Network
The extension makes no network requests of its own, with one exception you choose: when you turn notifications on for a site, it fetches that site's own RSS or Atom feed every 30 minutes, without cookies, to tell you about posts you haven't seen. Nothing is sent with that request beyond what any feed reader sends.
No analytics, no account, no advertising, no remote code. Nothing is sold or shared.
Permissions
| Permission | Why |
|---|---|
| Access to a site | Asked for when you turn Nihil Novi on for that site, so it can see and hide its feed. Given back when you turn the site off. |
storage | To keep the settings and fingerprints above. |
scripting | To run its page script on the sites you turned on. |
activeTab | So the toolbar button knows which site you're on. |
alarms, notifications | For the RSS check every 30 minutes and its notification, only when you turn notifications on. |
Removing it
Turning a site off deletes everything stored for it. Removing the extension deletes everything it stored.
