5 Best CamScanner Alternatives in 2026: Private Scanner Apps Compared

With 520 million downloads and 300 million users worldwide, CamScanner is one of the most popular document scanner apps. But after a 2019 malware incident discovered by Kaspersky and a 2021 executive order citing privacy concerns, many users are looking for alternatives.

In this guide, we compare CamScanner alternatives based on one critical question: Where do your documents actually go?

Why Users Are Leaving CamScanner

The 2019 Malware Incident

In August 2019, security researchers at Kaspersky discovered malicious code in CamScanner versions released between June 16 and July 25, 2019. The malware, identified as Trojan Dropper, could:

• Extract and run malicious code from encrypted files
• Display intrusive advertisements
• Sign users up for paid subscriptions without consent

Google removed CamScanner from the Play Store. The company blamed a third-party advertising SDK from AdHub. The app returned to the Play Store on September 17, 2019, after removing the malicious code.

The 2021 Executive Order

On January 5, 2021, Executive Order 13971 banned transactions with CamScanner and seven other Chinese-developed apps, citing concerns that these "applications may access and steal personally identifiable information."

The order was later revoked by the Biden administration on June 9, 2021, but the privacy concerns it raised remain relevant.

Current Privacy Concerns

According to CamScanner's current privacy policy:

• Documents are uploaded to CamScanner's servers for processing
• The app collects device info, IP addresses, and usage data
• Data is shared with affiliates and third parties "under certain circumstances"
• Data is encrypted "if possible" (not guaranteed)

Making the Switch

If you're currently using CamScanner, here's how to migrate:

1. Export your documents: In CamScanner, export important documents as PDFs
2. Download your new app: We recommend ScanDash for maximum privacy
3. Import existing PDFs: Most apps can import from Files
4. Delete CamScanner: Uninstall and optionally delete your account

The Bottom Line

If privacy is your priority, choose an app that processes documents on your device. CamScanner, Adobe Scan, and Microsoft Lens all upload documents to cloud servers. Only ScanDash and Apple Notes keep everything local.

Your receipts, tax forms, medical records, and contracts contain sensitive information. Before scanning them, ask: where does this document actually go?
