The easiest way would be to have a back-up "hard" copy sent to your email or Slack.
To do this, press the 'Send' button in the top right corner of the note that you would like a copy of.
You can send your notes to your email inbox or to Slack.
If you are sending over email, the recipient list will auto-populate with the names of the meeting attendees. However if you just want to send it yourself, you can click on the x's and remove the others from the list.
If you are sending via Slack, you can select a public channel, a private channel, or get the bot to send a direct message.
