fixupxer

NeatCode-Labs

fixupxer preview

Android URL cleaner: strips tracking, rewrites social links for better previews, no permissions, no network. GPL-3.0-or-later.

  • Stop carrying tracking tags into the next chat. Remove known tracking parameters before copying, sharing, or opening a link. For example, example.org/read?article=42&utm_source=chat becomes example.org/read?article=42: the article selector stays. Browser Mode can do this for links Android sends to FixupXer, then open your usual browser.
  • Notice an email address or sign-in token before passing it on. Private Link Guard flags certain sensitive values still present in a URL. Review them, remove a parameter, or go back. It runs offline, but cannot detect every private value or tell whether one was included intentionally.
