Kefal Mobile

Kefal Mobile helps you understand how the observable security and integrity signals of your Android phone evolve over time.

The app performs lightweight checks and presents the results in simple language. Depending on your device and the available evidence, Kefal can examine:

- Android integrity and hardware-backed attestation

- Network, DNS and TLS consistency

- Kefal application integrity

- Battery and thermal posture

- Changes compared with your device’s own history

Results are deliberately clear:

- Everything looks normal

- A change needs your attention

- Not enough information yet

Kefal Mobile protects its measurements with keys stored in Android Keystore when supported. Measurements are encrypted in transit. If your phone is offline, signed events can be stored securely and sent when connectivity returns.

Privacy by design:

- No access to the content of your messages

- No access to your photos or contacts

- No camera, microphone or precise-location permission

- No advertising identifier

- Account and associated data deletion available from the app and website

Kefal Mobile can be used with a secure invitation from your organization or Kefal administrator. Setup, device verification and status explanations are designed to remain simple for non-technical users.

Important limits:

Kefal Mobile provides technical security and integrity signals, not absolute proof that a device is safe. Android isolates applications from one another, so Kefal cannot inspect every process or detect every possible form of malware or commercial spyware. A normal result does not guarantee that Pegasus or another advanced threat is absent. If you believe you are specifically targeted, contact a qualified incident-response or digital-forensics professional.

Available in English, French, Spanish, Portuguese, Italian, German, Russian, Hebrew and Arabic.
