iShredder™ — Flagship Product

Deleted doesn’t
mean gone.

You’re selling your old smartphone. The data? You thought it was deleted long ago. But it’s still there — recoverable with free software in under ten minutes. iShredder overwrites it according to international standards (NIST 800-88, DoD 5220.22-M) and provides a certified erasure report — GDPR-compliant.

  • GDPR-compliant erasure report — verifiable proof for audits and regulators
  • 23 erasure algorithms — from NIST SP 800-88 to DoD 5220.22-M ECE
  • DEKRA MASA L1 validated — the only app of its kind

  • The world’s first & only certified anti-spyware app
  • 99.87% detection rate — AV-TEST, January 2024
  • Dark Web Check: See whether your data has been compromised

Antivirus AI — Android & Mac

Two engines.
Zero gaps.

Traditional scanners know yesterday’s malware. Deep Detective™ recognizes the behavior of tomorrow’s threats. Both engines run in parallel — what one misses, the other catches. In real time. Without your data ever leaving the device.

  • Your Mac scans iPhone & iPad too — via USB, no cloud required
  • Native for Apple Silicon — M1 through M4, without draining your battery
  • Apple-notarized — verified by Apple’s Notary Service for known malware
Antivirus AI

No technical expertise required. Ready to go immediately — an account is optional.

1

From Google Play, the Mac App Store, or directly from protectstar.com. In seconds.

2

Open it

No setup required. Optional: Use a free MY.PROTECTSTAR account to manage multiple devices in one place.

3

Why Protectstar

Security you don’t notice.
Except when it saves you.

Zero data collection.

No tracking. No ad IDs. No profiles. What happens on your device stays on your device.

Independently tested.

AV-TEST, DEKRA MASA L1, App Defense Alliance. The people who evaluate us have no ties to us.

Real AI — not just marketing.

Deep Detective™ learns with every scan and catches threats traditional scanners won’t see until days later.

Ad-free. Even the free versions.

No banners. No trackers. No subscriptions that quietly auto-renew. Even our free versions stay ad-free.

What We Stand For

What you do is
nobody else’s business.

Every Protectstar app scans locally on your device. No telemetry. No tracking. No data brokering.

No tracking
No analytics. No cookies. No fingerprints. Who you are is nobody else’s business.
No telemetry
No phoning home. No usage data. No device profiles. What you do is nobody else’s business.
No ads
No data brokers. No ad networks. No hidden agendas. What you buy is nobody else’s business.

Other vendors say “privacy” when they mean their data pipeline.
We mean privacy the way the word was intended.

Our vision

World-class protection for 1 cent a day — almost there already. Because security should never be a luxury.

Your personal Support Hero

Every purchase comes with a dedicated Support Hero — a real person with a name, not a ticketing system.

Trust through transparency

Independently tested.
Internationally awarded.
