Sync.com Alternatives for Encrypted Cloud Storage

Sync.com is still running and still sells end-to-end encrypted storage for one person. Its individual pricing page lists Personal 1TB, Solo 5TB and Personal Unlimited, with a 25% discount for the first year only. After that, Personal 1TB renews at $12 a month on annual billing, or $16 if you pay monthly. The free plan still gives 5 GB.

People leave Sync.com for three reasons that come up again and again: the renewal price, the missing Linux desktop client, and the 1 TB jump between free and paid. The services below keep files encrypted before they leave your device, or say plainly when they do not. Each one fixes at least one of those three problems.

Prices below are as of November 6, 2026. Our method is on How we review tools.

Quick comparison

Proton Drive

Proton Drive is the nearest thing to Sync.com with a cheaper first step. The Proton Drive pricing page starts paid storage at Drive Plus, 200 GB for $4.99 a month, so you are not forced to buy a full terabyte to get past the free 5 GB. Encryption works the same way in principle: files are encrypted on the device, and Proton cannot read them.

The bigger plans bundle other Proton apps. Proton Unlimited gives 500 GB plus Proton VPN and Mail for $12.99 a month, and Proton Family shares 3 TB across up to six people for $29.99 a month. A business tier, Drive Professional, gives 1 TB per user at $9.99 a month. CHF and EUR prices sit behind the same page.

Best for: People who want Sync.com-style encryption but only need a few hundred gigabytes.

Pricing:

• Free: 5 GB
• Drive Plus: 200 GB, $4.99 a month
• Proton Unlimited: 500 GB plus VPN and Mail, $12.99 a month
• Proton Duo: 2 TB for up to 2 users, $19.99 a month
• Proton Family: 3 TB for up to 6 users, $29.99 a month
• Drive Professional: 1 TB per user, $9.99 a month
• Prices shown with monthly billing; yearly billing is cheaper per month

Watch out for:

• Desktop apps are listed for Windows and macOS plus a command-line tool. There is no Linux desktop sync app on the pricing page, the same gap Sync.com has.
• The largest single-person plan is 500 GB. To get 2 TB or more you buy Duo or Family, which are priced for households.

Tresorit

Tresorit sells end-to-end encrypted storage with more control over shared links than most consumer services. Paid personal plans let you require email verification on a link or turn off downloads, two controls that matter if you send contracts or medical files to people outside your account. Its personal tiers are Lite with 50 GB, Essential with 1 TB and Pro with 4 TB.

The free option is small. The Tresorit Basic page lists 3 GB of encrypted space, uploads up to 500 MB per file, sync on two devices and 10 encrypted links a month. That is enough to test the desktop apps on Windows, macOS and Linux before paying, and each paid tier has a 14-day trial.

Best for: Freelancers and small offices who share sensitive files with clients and want link controls.

Pricing:

• Basic: free, 3 GB, 500 MB per file, 2 devices, 10 links a month
• Personal Lite: 50 GB, 2 GB per file
• Personal Essential: 1 TB, 10 GB per file
• Personal Pro: 4 TB, 10 GB per file
• Monthly or yearly billing; prices not published
• 14-day trial on paid plans

Watch out for:

• Per-file caps are tight next to Sync.com. Lite stops at 2 GB per file and even Pro stops at 10 GB, which rules out large video masters.
• The free plan syncs only two devices, so a laptop, desktop and phone already exceed it.

Official site: Tresorit.

pCloud

pCloud is the main reason people stop renting storage. The pCloud plans page lists Premium 500 GB for $279, Premium Plus 2 TB for $709 and Ultra 10 TB for $2,799, all as one-time lifetime payments. At Sync.com renewal rates, 2 TB of storage would cost more than that within a few years.

The pCloud Drive desktop app is listed for Windows, macOS and Linux, and it shows cloud files as if they were local without using disk space, so a large library does not have to be copied to the laptop first. The free account goes up to 10 GB.

Best for: Buyers who want 2 TB or more and would rather pay once than renew every year.

Pricing:

• Free: up to 10 GB
• Premium 500 GB: $279 once
• Premium Plus 2 TB: $709 once
• Ultra 10 TB: $2,799 once
• pCloud Encryption add-on: $229 once
• Monthly and annual plans also exist

Watch out for:

• Files are not end-to-end encrypted by default. The pCloud Encryption page sells client-side encryption as an extra, $229 lifetime, and it covers only what you put in the Crypto folder.
• A lifetime plan is a bet on the company. Prices can change, so check the page on the day you buy.

Official site: pCloud.

Filen

Filen is a German service, and its home page says the company headquarters and all servers are in Germany. Everything is zero-knowledge end-to-end encrypted, and the company says all of its apps are open source, a claim Sync.com does not make. Desktop clients cover Windows, macOS and Linux, and there is a command-line tool.

Prices are low. Pro I gives 200 GiB for 1.99 EUR a month, Pro III gives 2 TiB for 8.99 EUR, and Pro X reaches 10 TiB for 39.99 EUR. The free tier is 10 GiB with no card, twice what Sync.com offers.

Best for: Linux users and anyone on a budget who still wants end-to-end encryption.

Pricing:

• Free: 10 GiB
• Pro I: 200 GiB, 1.99 EUR a month
• Pro II: 500 GiB, 3.99 EUR a month
• Pro III: 2 TiB, 8.99 EUR a month
• Pro X: 10 TiB, 39.99 EUR a month
• Annual billing available

Watch out for:

• The pricing page shows euro prices only. Buyers in the US or Canada pay in euros and take the exchange rate.
• Its FAQ raises the question of a lifetime plan, but no lifetime tier appears in the plan list today.

Official site: Filen.

Internxt

Internxt sells encrypted storage in 1 TB, 2 TB and 5 TB sizes, on yearly or lifetime terms. Lifetime plans can be stacked up to 100 TB, per the FAQ on its pricing page, and Klarna can split a lifetime purchase into installments. A 30-day money-back guarantee covers paid plans.

The free account is 1 GB and needs no identity or email check. Apps run on Linux, Windows, macOS, iOS, Android and the web. Lifetime plans are often discounted, so compare against the regular price.

Best for: People who want a lifetime plan with end-to-end encryption and a Linux app.

Pricing:

• Free: 1 GB
• Essential: 1 TB, annual or lifetime
• Premium: 2 TB, annual or lifetime
• Ultimate: 5 TB, annual or lifetime
• Prices change often with sales
• 30-day money-back guarantee

Watch out for:

• The iPhone app is rated 2.8 out of 5 from 81 ratings on the App Store, with reviews describing uploads that fail partway and storage that still shows as used after deletion.
• Frequent discounts make it hard to know the real price. Compare the checkout total with the plan size before paying.

Official site: Internxt.

MEGA

MEGA gives the largest free tier here, 20 GB with zero-knowledge encryption and no card, per its App Store listing. It is also a common way to send a big file as a link, because the recipient does not need an account. Paid tiers on iOS run from PRO LITE at $6.49 a month to PRO III at $37.49 a month, with PRO I at $12.49 a month for 3 TB of storage and 3 TB of transfer.

Transfer quotas are the part Sync.com users notice. Sync.com lists unlimited share transfer on paid plans, while MEGA meters how much you and your link recipients can download. We compare more MEGA options in our MEGA alternatives guide.

Best for: Users who need lots of free space and send large files by link.

Pricing:

• Free: 20 GB
• PRO LITE: $6.49 a month or $79.99 a year (iOS)
• PRO I: $12.49 a month or $124.99 a year, 3 TB storage and transfer (iOS)
• PRO II: $24.99 a month or $249.99 a year (iOS)
• PRO III: $37.49 a month or $374.99 a year (iOS)
• Essential: $59.99 a year (iOS)

Watch out for:

• App Store reviewers complain that bonus storage on free accounts expires after 30 days, and that over-quota accounts get locked.
• Free accounts hit transfer limits on large downloads, according to several App Store reviews.

Official site: MEGA.

Dropbox

Dropbox is on this list for people who chose Sync.com for its price and sharing, not mainly for encryption. Its sync engine and its app integrations have years of polish, and Plus gives 2 TB to one person for $9.99 a month on the plans page. Standard is $15 per user per month for teams, starting at 3 TB shared.

The privacy trade is real. Dropbox's end-to-end encryption page lists the feature only on Advanced, $24 per user per month, as zero-knowledge folders for teams. On Basic and Plus, Dropbox can technically access your files, which Sync.com cannot.

Best for: Teams that care more about sync reliability and integrations than zero-knowledge storage.

Pricing:

• Basic: free, 2 GB
• Plus: $9.99 a month, 2 TB, 1 person
• Standard: $15 per user per month, from 3 TB
• Advanced: $24 per user per month, from 15 TB, with end-to-end encrypted folders
• Enterprise: contact sales

Watch out for:

• End-to-end encryption is missing from Plus and Standard. It starts at the Advanced team plan.
• The free Basic plan holds only 2 GB. Of the services here, only Internxt gives less free space, at 1 GB.

Official site: Dropbox.

How to choose

When to stay with Sync.com

Stay with Sync.com if you need one large plan for one person with unlimited share transfer. Personal Unlimited has no storage cap and keeps 365 days of file versions, and none of the encrypted rivals here sells unlimited space to one user. Version history is also long on every paid tier, 90 days on Personal 1TB and 180 on Solo 5TB. If you run your own server instead, our Pydio alternatives cover self-hosted file sharing.
