# Sync.com review

A Canadian, end-to-end encrypted cloud storage service positioned as a private Dropbox alternative, with a free 5GB tier and paid plans from $4/month (150GB).

By Noah — last updated & pricing verified September 15, 2026.

> **Sync.com** is a cloud storage service built around zero-knowledge, end-to-end encryption: files are encrypted before they leave a user's device, so Sync.com cannot decrypt or view stored content even if compelled to. This is the core differentiator against mainstream competitors like Dropbox or Google Drive, which can technically access unencrypted file contents.

The service targets both individuals and businesses, with dedicated plans for education, healthcare, legal, financial services, government, and content-creator use cases. Individual plans include a free 5GB tier, Personal 150GB at $4/month ($3.50/month billed annually), Personal 1TB at a promotional $8/month ($6/month billed annually, listed against a regular price roughly double that), and Pro Solo 5TB at $16/month ($14/month billed annually) with advanced sharing and custom branding. Business and team plans, including an unlimited-storage Pro Teams Unlimited option, are priced separately. Sync.com runs on web, Windows, Mac, iOS, and Android, and includes a CloudFiles feature that integrates with Windows Explorer and Mac Finder, plus custom-branded client file portals for professional sharing.

## Facts

- Website: https://sync.com
- Pricing: Free tier · paid from $4/mo (verified undefined NaN, NaN)
- License: Freemium
- Platforms: web, windows, macos, ios, android
- Best for: privacy-conscious individuals and regulated businesses (legal, healthcare, finance) who need zero-knowledge encrypted file storage that even the vendor cannot read
- Standout feature: True end-to-end (zero-knowledge) encryption on all stored files, meaning Sync.com cannot decrypt user content even under legal compulsion, unlike mainstream competitors that can technically access unencrypted files.
- Biggest weakness: Reviewers report real reliability problems including slow performance and basic operations like folder creation failing at times, along with slow customer support response times where users describe having to perform their own recovery steps after minimal guidance; because encryption is end-to-end, a lost password also means permanently lost access to files with no vendor-side recovery.
- Third-party ratings: Capterra 4.3/5 (57 reviews)
