Score History
Timeline events are AI-curated from public reporting. Score trajectory is derived from documented events.
Sync.com launches its public beta with zero-knowledge encryption as the default on a 5GB free tier. The product is minimal — desktop sync for Windows and Mac plus web access — but the core privacy promise is established from day one. As a bootstrapped startup by former Netfirms founders, there are no external investors or monetization pressures. The main limitation is a narrow feature set compared to Dropbox and Google Drive.
Sync.com matures beyond beta with improved mobile apps and sharing features, but remains a small player in encrypted cloud storage. The company publicly opposes Bill C-51's surveillance expansions, establishing its identity as a privacy advocate. Canada's Five Eyes membership introduces a persistent jurisdictional concern. The closed-source desktop client means zero-knowledge claims remain unverifiable, though no breaches or incidents have occurred.
Sync.com proactively implements GDPR compliance and launches Web Panel 3.0 with document previews and a redesigned interface. The desktop app reaches v2.0 with 64-bit support. As competitors like Tresorit begin publishing independent security audits, the gap in Sync.com's transparency on encryption verification becomes more noticeable. The product remains feature-limited compared to mainstream cloud storage, with no API and no Linux support. Annual-only billing is the only option.
Sync.com reaches 1.9 million users and completes its SOC 2 Type 1 audit, providing the first independent verification of operational security controls. New Pro Solo Professional and Teams Unlimited plans expand the product line, and CloudFiles beta adds files-on-demand. Slack integration represents a rare third-party connection. Monthly billing options and phone support address long-standing user complaints. The bootstrapped model continues with no external funding, though competitors like Proton Drive launch with open-source clients and published audits, increasing transparency pressure.
Dropbox's decision to end unlimited storage in August 2023 drives a significant influx of users to Sync.com, pushing storage capacity past 230 petabytes. The Pro Teams+ Unlimited plan launches with enterprise features like RBAC and 2FA enforcement. Desktop app reliability issues emerge with recurring Mac crashing, sync failures, and network connectivity problems requiring multiple bug-fix releases. The password recovery feature's temporary break of zero-knowledge encryption and the Enhanced Privacy toggle for shared links add complexity to Sync.com's security claims.
Sync.com maintains its position as a healthy, privacy-focused cloud storage provider with 2.5 million users and $5-10M in annual revenue. Desktop app reliability complaints emerged in 2024-2025, and the gap between zero-knowledge marketing and verifiable evidence widened as competitors like Tresorit and Proton Drive published independent audits. The password recovery feature's temporary break of zero-knowledge and the enhanced privacy toggle for shared links added nuance to security claims. The bootstrapped, founder-led model continues to resist enshittification pressures.
Alternatives
Swiss-based encrypted cloud storage with open-source clients and published independent audits — stronger privacy credentials than Sync.com. Part of the Proton ecosystem (Mail, VPN, Calendar). Free tier offers 5GB. Pricing starts at $4.99/month for 200GB. Easy switch — download files from Sync.com and upload to Proton Drive. Scored 18 here (Healthy).
Swiss-hosted encrypted cloud storage with published independent security audits, HIPAA/GDPR compliance, and enterprise-grade access controls. More expensive than Sync.com ($11.99/month for 1TB) but offers the strongest independently verified encryption in the market. Best for businesses handling sensitive data. Easy switch — standard file download/upload.
Swiss-based cloud storage with a unique lifetime plan option (one-time payment for permanent access). Offers 10GB free tier and strong media playback features. Caveat: full end-to-end encryption requires the paid pCloud Crypto add-on — not included by default like Sync.com. Easy switch with standard file transfer.

Sync.com publicly opposes Canada's Bill C-51 surveillance law
Sync.com joins over 200,000 Canadians in opposing Bill C-51, the Anti-Terrorism Act of 2015.
