Never fully works…

Sync has a great mission statement. And the idea that all data is handled securely plus the share features are all very cool. However, the platform continues to be glitchy at times. And somehow always in critical moments when I need to look at a file on my cellphone and it won’t “sync”. Or when I want to upload a file from my cellphone and it also won’t sync.

Seamless photo sync

Easily connect to my phone’s photo app and upload images. The web app’s uploading experience is a lot more painful. I’m migrating from google drive and uploading large number of files has been a pain. The error message was confusing. The number of files to include each upload (so that it doesn’t error out) seems arbitrary and a lot lower than the FAQ said the web app could handle.

Issues with vault

Wanted to support a Canadian business but there are tons of issues with listening to audio files via vault. Sometimes it doesn’t even play, and you can’t listen while the app is minimized. Not worth your money until they make it usable.

Great overall

…. but I get the impression that whoever wrote the audio player decided to add a (non) feature to change the brightness at a swipe did this to show off rather than provide any benefit to the user. The ‘black screen’ feature is useless! Even the volume control swipe is annoying. Doesn’t replicate any gesture a user is used to.

👌🏼cause you know it’s real when you see them 2 fingers touch #clockIt

Great company with a great product. Have used them for many years and recommend to all who value privacy and security.

Worth the money

I’m writing this for a feature request after i upload photos it would be very useful to able to delete them from the app. And make the upload faster.

I have the 150gbs subscription after that gets full probably go bigger. The app is all round great, encrypted, private, affordable, automatic upload.

So far So good

Over all satisfied with free version, and would definitely like to try the paid version. Only downside with paid plans are like there are nearly less or no options available for light weight uses such as 100, 200 gb or 1TB.

Very good

Very good

Good app. Limited search

My biggest complaint is the search facility. Very limited. No regex or smart search capability. Otherwise I use it every day

Awesome

Great service.

Great App

Love it work as advertised.

Decent but could use some tweaks

The app works really well as compared to other file/cloud storage platforms - happy overall. That said, I still find the UI/UX a bit clunky and cumbersome at times, especially as compared to Dropbox. Hopefully that’ll be improved as time goes on. Would recommend regardless though.

Woeful iPhone syncing

It’s absolutely woeful at syncing photos from iPhone. Constantly stalls, it’s quite infuriating. I’ve used for years but I think I’ll be cancelling before renewal this year. There are better options.

sending me emails after i deleted my acc

.

Make it difficult to unsubscribe. And even when I did then still billed me.

CANCELLED MY SUBSCRIPTION AND MY SYNC ACCOUNT CONFIRMED IT WAS CANCELLED.

THEY TOOK PAYMENT ANYWAY AND NOW MY ACCOUNT SHOWS AS RENEWED.

WITHOUT MY CONSENT!!!
THAT IS CALLED THEFT!!

REPORTED THEM FOR FRAUD TO MY BANK AS I HAVE SCREENSHOTS SHOWING I CANCELLED AND IT WAS CONFIRMED ON MY SYNC ACCOUNT AS CANCELLED.

MY BANK HAVE CONFIRMED THEY WILL BE CREATING A CHARGE BACK AND I WILL GET MY MONEY BACK AS THIS I BLATANT FRAUD.

You can tell from how the site is laid out and how awkward that make it to cancel that they are one of the sly companies with no morals.


As for the product….

For work I switch a lot between my phone and PC and needed an app that I could would on my phone then as soon as I’m back at my desk jump straight onto my PC and continue where I left off.

I also need encryption as I handle customers private data.

I tried around 5 or 6 options and Sync was without doubt the worst.

It would sometimes take hours to sync. (For comparison Standard notes syncs in seconds, Proton Drive/Pass syncs in around a minute or so)

And often it didn’t sync at all and even sometime erased files.

I had files that were synced between the app and desktop version then one day the file would vanish off my app but still be on the desktop.

Their app shouldn’t even be allowed to market. It does not work. And I’ve read enough reviews of many people reporting the same thing for a long time.

But they haven’t bothered to make any attempt to fix it.

Seriously, avoid this app/company like the plague. It doesn’t work. It loses files, the company has made no attempt at rectifying the issues with their app despite so many reviews all saying similar.

They can not be trusted and I wouldn’t be surprised after what I’ve seen if it turns out their encryption has a back door.

I really wouldn’t trust this company whatsoever.

For me Standard Notes is absolutely fantastic. Syncs between devices almost instantly. The free version only had limited features and if mainly just for notes/record.
But they laid version does have file storage and load of more advanced features. Standard notes is my main go to.

But I also use Proton Drive for backups and file storage.

Proton is good if you want a wider range of features. Like file storage, Proton pass for notes and logins. (Be warned though Proton Pass does not have an auto save feature, which is one of the main reasons I don’t use is as I’ve accidentally lost data.

But those 2 options are the best.

I have used numerous others.

Sync was without question the worst in every aspect.

Great!

So glad I found this company and app

Avoid like the plague

The amount of errors and missing files and folders from this service is unbelievable. Avoid it like the plague. Do not use for your files!

Doesn't work on iOS

I'm starting to get rather frustrated with these guys, honestly. Despite how crude and simple the system is on PC (which I deleted and purged due to syncing problems filling up my hard-drive, and poor clarity regarding how things are being synced and organized, etc) and online in desktop browsers (can't even see how many files are contained in a folder, or how large the data inside a folder is), they're still struggling to get products to work at all.

This iOS app won't even let me log in even once: when I don't get an incorrect login credential failure, I get an internal server error trying. A pop-up asks if I want to send logs to understand the error, but then it hets stuck spinning on "sending logs" interminably. I won't be upgrading my storage subscription anytime soon until this whole ecosystem gets a lot more user-friendly.

Simply the best

Better then all the rest ;)

Terrible support

Maybe it works, maybe it doesn’t. I’ve been trying to load large amounts of photos, so multiple files with smaller file sizes, and the software continues not to upload all the files.

You cannot get a live technical support agent, no matter what you do or say. I’ve now emailed back and forth four times before they’re willing even to consider letting me speak to a person.

So maybe it’s a setting on my computer. I’ve tried multiple browsers. They’ve told me to delete any cookies. Turn off and delete any extensions, and upload in incognito mode. None of it is working correctly.

The user interface for this app is absolutely fantastic, which is why I switched to it: it makes it easy to share files while still keeping them encrypted. But when you’re trying to load 4 TB worth of data, and you can’t get 100 GB loaded correctly, it’s impossible to use.
