About Cookie Sweeper - Auto-Delete Cookies
Every site you visit leaves cookies behind. Most of them track you long
after you've left. Deleting them all breaks your logins; keeping them all
means being followed everywhere.
Cookie Sweeper does what you'd do manually if you had infinite patience:
it waits until you close a site's last tab, gives it a short grace period,
then removes that site's cookies - unless the site is on your keep list.
WHAT IT DOES
- Auto-sweep: when you close a site's last tab, its cookies are deleted
after a grace period you choose (1 to 15 minutes)
- Keep list: sites you want to stay signed into are never touched -
Gmail, banking, work tools stay logged in
- Reopened the site during the grace period? Nothing gets deleted.
- Manual mode: sweep any site's cookies with one click, whenever you want
- Live counter: see how many cookies the current site has set
- Stats: cookies removed since install
SAFE BY DEFAULT
Cookie Sweeper starts in manual mode. Build your keep list first (one
checkbox per site), then enable auto-sweep. No surprise logouts.
PRIVATE BY DESIGN
- No data collection, no analytics, no external servers
- Everything happens locally in your browser
- Human-readable source code in the package (no minification)
PERMISSIONS
- "Read and change data on all websites" + cookies: required to list and
delete cookies for the sites you close. That is the only use.
- tabs: to know when a site's last tab was closed
- alarms: for the grace period timer
A NOTE ON SUBDOMAINS
Sites are grouped by their main domain (shop.example.com and example.com
count as one site), so shared logins across subdomains are handled sanely.
