Private mode for journal entries

[alexpunct]

As a user I would like to be able to lock my journal entries so that they cannot be read by someone with access to the database or someone with access to my device.

There are 2 parts to this:

1. Lock the frontend somehow with a PIN. Automatically lock after some time (let's say 5 minutes of inactivity).

2. Encrypt the journal entries and decrypt them on the frontend client. There are a few potential issues here:

• the user would be responsible for remembering/storing their private key (which they could lose and lose access to the data)
• the backend might not be able to analyze the entries properly

It would be good to initiate a discussion on this topic and brainstorm some clever ways of achieving privacy while not burdening the user too much or risking losing their precious data.

(there are some potential tools like oasislabs.com where the user could store/own their data although that's also on someone else's computer)
