Just as a counter data point, I've never lost a note and it's been very dependable for me for at least 5 years or so. Still makes me nervous though now and then.

But if you're worried about it you can set it up so that it keeps a local copy of your note library as well, just in case.

"Ditto". Longtime user (of the iOS app) and have never lost a note that I can recall.

At it's very core, Simplenote relies on a library called Simperium (http://github.com/Simperium/simperium-ios/).

In the past few months / years, we've significantly improved both, it's performance and reliability.

Sync'ing bugs are taken very seriously, if you ever experience any kind of glitch, please: just let us know.

We'd be thrilled to have you back with us!

Yeah, it's funny I had the same experience with Evernote. Erased some notes during sync and I noped out of there. Went to Simplenote, which has been flawless for me but obviously your experience shows that the service isn't flawless.

I just wish there was a note company who made "don't lose data" the #1 priority and built the architecture around treating that concept like a religion.

Same here, I would regularly have sync issues. Sometimes I'd see it happen while I was actually in the process of writing still.

Sorry to hear! Next time you run into an issue, please don't hesitate to contact support/file an issue on Github.

Definitely something we haven't heard lately. Every version of every note is saved, so if something goes wrong with a bad client you can always log into the web interface and look up the history. If it ever happens again contact support and we can look into the specifics.
