Sino vs Cryptomator
Both encrypt your files on your own device before they reach Google Drive or any other cloud, so the provider stores data it cannot read. They take different routes to get there, and each is the better choice for different people.
Choose Sino if
- You want copies on more than one cloud at once, so one locked or lost account does not cost you your files.
- You want Sino to back up folders on your phone, such as Camera, WhatsApp or Downloads, without opening another app.
- You want a decoy vault, an emergency wipe, and a way to make a lost phone or PC wipe itself.
- You want Legacy Handover, so someone you trust can claim your vault if something happens to you.
Choose Cryptomator if
- You need it on a Mac, Linux or an iPhone today. Sino is on Android and Windows for now; Linux and iOS are planned next.
- You want software that is fully open source and has had an independent audit.
- You already rely on your cloud's own sync app and want encryption on top of it, for free on desktop.

The biggest difference: one cloud or several
Cryptomator encrypts a folder, and your cloud's own app (Google Drive for desktop, Dropbox, OneDrive) uploads it. That keeps Cryptomator simple, and it works with almost any cloud. But your files live with one provider, and the provider's app decides what gets synced and when.
Sino talks to each cloud itself, so it can keep the same encrypted vault on Google Drive and MEGA, or on S3 and Azure, at the same time. It merges the file lists from every cloud, so an old copy served by one provider cannot undo a deletion, and it can repair a cloud from the others. If one account is locked, closed or wiped, your files are still on the rest.
Protection when your phone is taken
Cryptomator protects what is in the cloud. Sino also plans for the device in your hand: a second password opens a believable decoy vault if you are forced to unlock, the Terminus Protocol wipes Sino from the device in one step, and a lost phone or PC that you revoke wipes itself the next time it connects. Your cloud copies stay safe either way.
None of this helps if spyware is already on your phone while Sino is unlocked. Read what Sino cannot protect you from before relying on it.
Where Cryptomator is ahead
Cryptomator is fully open source, has been independently audited, and runs on every major desktop and phone. Sino publishes only its recovery SDK and its cloud format, and has not had an independent audit yet. If those matter most to you, Cryptomator is the better choice today.
Moving from Cryptomator to Sino
-
1
Install Sino and create your vault
Follow Get Started: set a master password, write down your 24 words, and connect one or more clouds.
-
2
Unlock your Cryptomator vault
Open it in Cryptomator as usual, so its files appear as a normal drive or folder.
-
3
Add the files to Sino
On Windows, add the unlocked folder as a backup folder, or copy its files into the Local Vault. Sino encrypts them again in its own format and uploads them.
-
4
Check, then retire the old vault
When Sino shows the files as backed up on every cloud, open a few to check them, then remove the Cryptomator vault if you no longer need it.
Try Sino
Free on Windows. Set up a vault, connect your clouds and protect your first files in about five minutes.
