ScamGuard: Link Checker Privacy Policy

Last updated: June 2, 2026

ScamGuard: Link Checker is designed with privacy and transparency as core principles. This policy explains how the app handles data.

Operator identity

ScamGuard: Link Checker is a MiniFyn product operated by Sylvester Kumar Das (UDYAM-KL-12-0136086).

What we do NOT collect

  • No user accounts are required or created.
  • No advertising identifiers are used.
  • No third-party advertising or analytics SDKs are integrated in the app.
  • We do not build user profiles.

How ScamGuard: Link Checker works

  • URLs entered in the app are normalized and checked for security signals, reputation signals, redirect behavior, and AI-assisted risk signals.
  • Requests are sent to minifyn.com/api/linkguard/* for link analysis. The request may include the submitted URL or URL hash, app version, platform, and Play Integrity proof.
  • Temporary technical data (such as IP and request metadata) may be processed transiently for abuse prevention, reliability, and security.
  • The app may request AI model manifest metadata and signed model download URLs from minifyn.com/api/scamguard-ai/* to support AI-assisted risk analysis. These requests may include app version, platform, API mode or AI Mode claims, and Play Integrity proof. AI Mode controls access to full AI review details and subscriber features.

Native Android link protection

  • If you configure ScamGuard: Link Checker for Android quick checks, the app may inspect a link locally before handing it to your chosen browser.
  • Preferred browser settings and trusted quick-check domains are stored locally when you choose to configure them.
  • Links may be submitted to MiniFyn for analysis only when the app performs a link check.

Payments, Pro, and AI Mode

  • Pro is a Google Play managed one-time in-app product.
  • AI Mode is a Google Play managed subscription and includes Pro features.
  • Payments, renewals, cancellations, refunds, and payment methods are handled by Google Play under your Google Play account.
  • We do not store full card, bank, UPI, or payment method credentials on our servers.
  • We do not require creation of a personal account for Pro unlock.
  • Google Play and infrastructure providers may process and retain their own operational logs and transaction records under their respective policies.

Notifications

  • If you grant notification permission, Firebase Cloud Messaging may be used for daily safety tips and app announcements.
  • Topic subscriptions may include coarse delivery groups such as timezone offset topics and the app announcements topic. We do not use these topics to identify you personally.
  • You can turn reminders and announcements off in app settings.

Camera and QR scanning

  • Camera permission is used only when you choose to scan a QR code.
  • QR scanning runs on device. Links found in a QR code may be submitted for analysis only when you choose to check them.

On-device data

  • Link analysis cache is stored locally on your device.
  • Optional link history is stored locally on your device when enabled.
  • Pro and AI Mode unlock status are stored locally on your device.
  • AI model metadata and downloaded model files may be cached locally.
  • Preferred browser and trusted quick-check domain settings are stored locally when configured.
  • Device backup/restore behavior may depend on Android system backup settings.

Purchase restore responsibility

Purchases are managed by Google Play. If app data is cleared, the device is reset, or the app is reinstalled, you may need to restore purchases from the same Google Play account.

Children's privacy

ScamGuard: Link Checker is not directed at children under 13 and does not knowingly collect personal information from children.

Changes to this policy

We may update this policy from time to time. Changes will be posted on this page with an updated date.
