I have a problem committing to a program/site that says:
it’s all completely free
How can they stay in business? Is their business nothing more than data mining my files? Is that something I want to allow? Is that a long term strategy for viability?
That doesn't provide any more information to the average user -- which I thought was what was being asked for here. What's "Simperium"? Just a name they don't know to them.
Another vote for Simplenote - does exactly what it says on the tin. In 2-3 years of using it, I had only couple of issues with sync. When I reported them, support was super responsive and the issues were fixed with subsequent updates.
Simplenote is where I keep my plain text notes now (Notational Velocity on Mac and official app on Android). My local copy of notes reside in my Dropbox folder and my (pretty much) entire ~/ is backed up to CrashPlan cloud.
For notes or docs that need diagram etc I use Google Docs. Even my team uses the same (as part of the Google Apps suite).
What I love about Simplenote is that it does what it says - just plain text notes. No gimmicks, no extra load and bells and whistles.
But I have a feeling that they will shut it down soon. They had a paid tier and they removed it some time back. There has hardly been any update I guess and iirc they don't really update their Android app frequently either.
Do they encrypt the notes at client side before sending it their servers? I would love to use a self hosted app that has such a functional and minimal interface and clean sync feature.
