If I'm only using Grid Diary on one device, is sync necessary?
No, you won't need to enable it. Syncing is only necessary if you have multiple devices using the Grid Diary app. It is also a great backup method, if you ever have to replace or restore your device, simply download Grid Diary and sign in to your account, that’s why we recommend you to buy membership subscription.
Can Grid Diary sync with iCloud or Dropbox?
No. While not representative of all our users' experiences, we had quite a lot of cases of data loss and duplication with iCloud and Dropbox. Every user’s data is what we care first, this was not acceptable to us. So we've built our own servers for Grid Diary Sync from the ground up.
