LinkGuard 0.2.0 moves the scam lists to Dwarpal Labs' own server, makes reports private, and turns them into automatic community warnings. Like 0.1.0 it never blocks: "Open anyway" is always there.

Install or update

  • Updating from 0.1.0: download linkguard-0.2.0-foss.apk below and open it. It installs over 0.1.0, and LinkGuard stays your default browser.
  • New install: open the APK (allow "Install unknown apps"), then open LinkGuard → Set as default browser.

Android 8+. Telegram users: turn off Telegram's in-app browser so LinkGuard can see links.

What's new

  • Community warnings. When 3 or more different LinkGuard users report the same website within a week, everyone else sees an amber warning: "This link was reported as a scam by N LinkGuard users this week." Reports only ever cause this soft warning, never the red one, and well-known sites can't be reported into a warning.
  • Private reports. Settings → Report a link now sends the report privately to Dwarpal Labs instead of opening a public GitHub issue. Each report carries an anonymous code that is different for every website, so your reports can't be linked together or traced back to you. Reports are deleted after 30 days.
  • Lists kept off GitHub. The known-scam and known-safe lists now live on Dwarpal Labs' server, so scammers can't read them from the source code. The app checks the scam list by sending only a 4-byte fingerprint of a website's name, and downloads the safe list as signed fingerprints.
  • Faster server checks. Links not on the safe list may take up to 1 second to check; you'll see "Checking link…" if it takes longer than 300 ms. Safe-listed sites still open instantly.

Privacy

LinkGuard never logs, stores or sends the links you open. No accounts, analytics or trackers. Updated policy: https://dwarpallabs.com/linkguard/privacy

Known limitations (why this is still a pre-release)

  • Hindi and Tamil text is machine-drafted and awaiting native-speaker review
  • The scam blocklist is still small; community warnings need several reports first
  • Links opened inside Telegram's in-app browser, or by apps that open Chrome directly, never reach LinkGuard

Help wanted

  • Report scam links you receive: Settings → Report a link
  • Hindi and Tamil reviewers for the app's text
