# Timebased

> Timebased blocks distracting websites by default, allows only the sites and subreddits you approve, and enforces daily time limits per domain. Loosening your own rules requires email verification and a captcha, so impulsive unblocking is impossible.

## Description

Timebased is a self-control tool for people who are serious about reclaiming their attention. Instead of blocking a list of bad sites, it works the other way around: you build an allowlist of sites you actually want, and everything you have flagged stays blocked until you deliberately decide otherwise.
You can set daily time limits per domain, for example 15 minutes of YouTube or 10 minutes of news. A small on-page timer shows your remaining time, and once it runs out the site is blocked until 4 AM the next day. Reddit gets special treatment: you choose which subreddits are allowed, and everything else, including the frontpage, is blocked.
The key idea is asymmetry. Making your rules stricter is instant: blocking a site, lowering a limit or removing a subreddit takes one click. Loosening them is intentionally slow: adding an allowed site, raising a limit or unblocking anything requires signing in, completing a captcha and entering a confirmation code sent to your email. That friction is usually enough to outlast the impulse.
Your rules and usage are stored in your account and synced across devices through a web dashboard, where you can manage allowed sites, subreddits and time limits in one place. Sign-in works with one-time email codes, so there is no password to remember. The extension collects no browsing history and tracks only the time you spend on the domains you chose to limit.
