Not a blocker. Before you open a distracting site, it shows you how long it's been since the last time. You always decide.

About Thalassa — See it before you scroll it
Thalassa adds a calm pause before the websites that pull you into feeds.
It is not a hard blocker. When you open a managed site or drift into an infinite feed, Thalassa covers the page with one simple fact: how long it has been since the last time.
The Open button works from the first second. You can continue, or you can step away.
What it does:
- Pauses before distracting feed pages.
- Lets specific pages go straight through, such as videos, search results, DMs, and individual posts.
- Shows local daily timestamps so you can see your own pattern without scores, streaks, or shame.
- Lets you manage any website, with built-in defaults for YouTube, X, Reddit, Instagram, and TikTok.
- Stores everything on your device. No account, no server, no tracking, no ads.
Why feed-only mode matters:
Sometimes you need a website for a real reason. YouTube search, a specific video, Reddit comments, Instagram DMs, and single posts can go straight through. The pause appears
when you are entering the open-ended parts: home feeds, Shorts, Reels, Explore, For You, and similar pages.
Privacy:
Thalassa stores your managed sites, local pause timestamps, grace periods, and settings in Chrome's local extension storage. Nothing is uploaded. The optional "find my most-
visited sites" feature asks for Chrome's topSites permission only when you click it, and uses the result locally to suggest sites.
