Always. Greylisted sites survive until the browser closes.
The core of the whole thing, running quietly in the background.
Never cleaned, or cleaned only when the browser closes.
Cookies only, plus localStorage, or plus IndexedDB, CacheStorage and Service Workers.
Load the JSON your old extension exported and your lists come across.
How many cookies the current site has set, on the toolbar icon.
The whole interface, in both.
$9.99 once — no subscription
The core is free forever. Pro adds power-user extras — one payment, no subscription. We have no servers, so we don't charge you monthly.
Keep one rule set for work and another for personal browsing, and switch with one click.
Clean a site on every tab close while the cookie that holds your login survives.
Still zero network requests, even with Pro — your license is verified locally. It works offline, and it keeps working even if our payment infrastructure ever disappears. 30-day refund, no questions asked.
