  • If only they hadn't rolled their own sync service. So disappointing. Why would I want my private notes in the hands of a group of unknown guys who live in a police state with no freedom of information or privacy laws? Sure, I trust them, but I'm sure there are trustworthy guys in Afghanistan or Saudi Arabia as well. I still wouldn't trust a small, private sync service based in any of those countries. It would be foolish.
  • That makes zero sense. Large sync services are already subject to the laws of the countries in which they operate, so there's no difference between using iCloud or Dropbox or using Vesper Sync in that regard. (Vesper Sync uses Microsoft Azure, fwiw, which is a fairly big company.) Vesper has a privacy policy. They have a business which depends on their reputation. They're aligned with my interests as a user. I use iCloud, Google, and several app-specific syncing services. What I insist upon is it being rock-solid and up-front with their terms. They've done both. What would be foolish would be to trust any online service anywhere that didn't have you roll your own keys and maintain them yourself (trust no one environment), which, sadly, isn't something any mainstream user would do.
