Can Is This Safe? detect phishing emails?

Yes. The email header analyser performs live DNS lookups to verify SPF, DKIM, and DMARC authentication records. It cross-references what the email headers claim against actual DNS records, detecting forged authentication results. It also checks for sender spoofing, Reply-To mismatches, display name impersonation, and suspicious routing. Results include an authentication score, sender score, and content score with actionable recommendations.

Is the Is This Safe app free to use?

Yes, completely free. Is This Safe? has no ads, no subscriptions, no in-app purchases, and no premium tiers. All five scan types — URL, message, QR code, file, and email header analysis — are available at no cost. The app is and will remain free.

Does Is This Safe? store my personal data?

No. Is This Safe? is privacy-first by design. Your scan history is stored locally on your device, not on external servers. The app only sends the URL, text, or file metadata needed to perform the safety check. No personal information, contacts, or full file contents are ever transmitted. The app is fully compliant with UK GDPR and the Data Protection Act 2018.

How does the QR code scanner in Is This Safe work?

Point your phone camera at any QR code. The app decodes the QR code and automatically runs a full safety scan on the decoded URL or text, including real-time DNS verification, phishing detection, typosquatting checks, and brand impersonation analysis — all before you visit the link. This protects you from malicious QR codes found on posters, emails, and packaging.

Is the Is This Safe app compliant with UK GDPR?

Yes. Is This Safe? is fully compliant with UK GDPR and the Data Protection Act 2018.

Camera

File Scanner

Analyse any file's metadata, extension, and SHA-256 hash. Deep scan checks magic bytes, detects hidden macros, and identifies steganography.

Deep Scan

Email Header Analyser

Paste raw email headers to verify SPF, DKIM, and DMARC authentication. Detects sender spoofing, forged results, and suspicious routing.

Auth Check

Quarantine System

Dangerous items are isolated in quarantine for your review. Examine threats in detail, then choose to restore or permanently purge each one.

Secure

Technology

Real-time DNS verification

Every scan queries live DNS servers. No stale blocklists. Catches brand-new scam domains within minutes of creation.

Domain existence

Verifies the domain actually resolves with A and AAAA records. Non-existent domains are immediately flagged.

Mail server records (MX)

Checks if the domain has mail servers configured, catching fake email sender domains.

SPF, DKIM, and DMARC

Validates email authentication records and cross-references them against header claims.

NS, CAA, CNAME, and TXT
