Sync.com — Free Service Overview

Sync.com is an end-to-end encrypted cloud storage service operated by Sync.com Inc., headquartered in Toronto, Canada. Sync.com was founded in 2011 and has been continuously offered as a consumer and business cloud-storage service since then. Sync.com positions on three pillars: end-to-end zero-knowledge encryption by default on every plan (no opt-in toggle, no add-on), a published security model documented at sync.com/security, and competitive per-TB pricing on individual and team tiers.

Quick facts · Jurisdiction: Canada (Five Eyes; zero-knowledge architecture protects data) · Encryption: AES-256 + RSA-2048 + TLS, zero-knowledge by default · Free tier: 5 GB · Pro Solo 2 TB: $8/mo · Team tier: $5/user/mo annual for 1 TB · See live pricing table below.

What is Sync.com?

Sync.com routes file-storage data through end-to-end encrypted tunnels with a zero-knowledge architecture: every file is encrypted on the user's device with keys derived from the user's credentials before transmission. Sync.com's servers see only ciphertext — they cannot decrypt files even under legal compulsion. The product launched in 2011 and ships native client apps across Windows, macOS, iOS, and Android, plus a browser-based web vault.

Why choose Sync.com

Privacy by design

Sync.com uses zero-knowledge end-to-end encryption by default on every individual and team plan — there is no encryption-feature split between Free and paid tiers. The security model is documented at sync.com/security: AES-256 for symmetric encryption, RSA-2048 for asymmetric key wrapping, TLS for transit. The Canada jurisdiction is a member of the Five Eyes intelligence-sharing arrangement, which is a relevant consideration for users in adversarial threat models — Sync.com's structural answer is the zero-knowledge architecture (there is no plaintext file content for legal authority to compel disclosure of).

Security beyond encryption

• Zero-knowledge architecture — vault contents are encrypted client-side; Sync.com's servers never see plaintext.
• AES-256 symmetric encryption + RSA-2048 asymmetric key wrapping + TLS in transit — documented at sync.com/security.
• Default-on encryption — every file on every plan is end-to-end encrypted; no opt-in, no add-on, no Crypto folder.
• Secure file sharing — share files with named recipients via expiring encrypted links with optional password protection.
• 30-day file history — restore previous versions of files within the published retention window.
• Selective sync — choose which folders sync to which devices.
• 2FA — TOTP authenticator support on the account login.
• Account recovery — recovery key issued at signup; without password and recovery key, encrypted file content is not recoverable.
• No tracking, no ads — subscription business model; no advertising-driven data harvesting.

Team and family pricing

Sync.com's team tier at $5/user/month annual for 1 TB per user is competitively priced for small businesses and freelance collectives. The team tier ships with shared folders, role-based access controls, and centralised admin controls suitable for small-team deployment. Team admin tooling includes activity logging and per-user storage quotas.

Pricing in 2026

Sync.com offers a Free tier with 5 GB, a Pro Solo individual tier, a Solo Professional tier, and Team tiers for organisational deployment.

The published rates are: Free 5 GB at no cost, Pro Solo 2 TB at $8/month annual, Solo Professional 6 TB, and Team tier $5/user/month annual for 1 TB per user. Every tier — including Free — uses the same end-to-end encryption.

Sync.com apps and platform support

Sync.com accounts have no per-account device cap on paid tiers — files can be accessed from every device the user owns. Linux users access the product via the web vault; native Linux desktop client is not available as of this writing.

Security audits and transparency

• End-to-end zero-knowledge encryption — vault contents are encrypted client-side with user-held keys; Sync.com's servers never see plaintext file content.
• AES-256 + RSA-2048 + TLS — security model documented at sync.com/security.
• Account recovery — recovery key issued at signup; if both password and recovery key are lost, encrypted file content is not recoverable (this is a deliberate consequence of the zero-knowledge architecture).
• Transparency report — see the vendor's transparency-report page for the most recent edition.

Use cases Sync.com fits

• Zero-knowledge-by-default users — Many cloud-storage providers offer end-to-end encryption as an opt-in toggle or paid add-on; Sync.com encrypts every file by default with no configuration required.
• Mid-priced E2E storage — Sync.com's Pro Solo at $8/month for 2 TB is priced between the cheapest non-E2E options and the most premium E2E offerings, fitting users who want zero-knowledge encryption without paying premium rates.
• Small teams — The $5/user/month annual team tier with 1 TB per user fits small businesses and freelance collectives that need shared encrypted storage with role-based access controls.
• Households with shared photo / video archives — Sync.com's selective-sync controls let households store a shared media library in cloud storage with per-device sync rules.
• Public Wi-Fi document workers — The end-to-end encryption protects documents from network observers on hotel, airport, and café Wi-Fi where TLS-only cloud storage might leak metadata.
• Privacy-conscious file sharing — Sync.com's expiring-link sharing with per-link password protection fits users who occasionally need to share sensitive files with named recipients.

Users who require native Linux desktop sync, or who want a free tier with substantially more storage than 5 GB, should evaluate Sync.com against those specific requirements before subscribing.

Frequently asked questions

Is Sync.com really end-to-end encrypted by default?

Yes. Every file on every plan — including Free — is encrypted on the user's device with AES-256 + RSA-2048 + TLS before transmission to Sync.com's servers. There is no encryption-feature split between Free and paid tiers. The security model is documented at sync.com/security.

How much does Sync.com cost?

The published rates are: Free 5 GB at no cost, Pro Solo 2 TB at $8/month annual, Solo Professional 6 TB, and Team tier $5/user/month annual for 1 TB per user.

Does Sync.com have a free tier?

Yes. The Free tier includes 5 GB of storage with the same end-to-end encryption as the paid tiers — there is no encryption-feature split.

Does Sync.com have a Linux client?

No native Linux client as of this writing. Linux users access Sync.com via the web vault at sync.com. Windows / macOS / iOS / Android have native clients with full sync.

Where is Sync.com based?

Sync.com is operated by Sync.com Inc., headquartered in Toronto, Canada. The Canada jurisdiction is a member of the Five Eyes intelligence-sharing arrangement; Sync.com's structural answer is the zero-knowledge architecture (encrypted file content cannot be decrypted by Sync.com's servers, so there is no plaintext data for legal compulsion to target).

Can I share files with people who don't have Sync.com?

Yes. Sync.com supports encrypted-link sharing with per-link permissions: optional password protection, configurable expiry, view-only or download-allowed. The recipient does not need a Sync.com account to access the shared file.

What is file history on Sync.com?

Sync.com retains 30 days of file version history on the published tiers. Users can restore previous versions of files (e.g. if a file is accidentally overwritten or corrupted by a sync bug) within the retention window.

What happens if I lose my password?

Sync.com issues a recovery key at signup that the user is expected to save offline. With the recovery key, users can regain access to encrypted file content. Without password and without recovery key, encrypted file content is not recoverable — this is a deliberate consequence of the zero-knowledge architecture.

Does Sync.com support team admin tooling?

Yes. The Team tier ships with shared folders, role-based access controls, activity logging, and per-user storage quotas. Team admin tooling is suitable for small-business deployment.

Can I migrate my files from another cloud-storage provider?

Yes. Sync.com supports import via the desktop client (drag-and-drop a folder from the source provider into the Sync.com sync folder) or via the bulk-upload web interface. There is no automated cross-provider migration tool; the desktop-client approach is straightforward for typical migrations.
