The Insight Notes notetaking code is very efficient. Our internal simulations suggest that most users of Insight Notes will store well under 100MB of data per year. Frequent and heavy users can expect to store somewhat more, approaching approximately 100-200MB of space per year, depending upon how many scans are taken. (Scans take up approximately 4X as much storage space as a text or drawing note.) It is highly unlikely that any single user, even one who mostly uses the scanning feature, would accrue more than 200MB of notes in a year. In the exceedingly unlikely event that you approach your storage limitations, all you have to do is contact us and we'll take care of you.
In the future we may provide additional storage capacity, but we are reasonably confident that users will not exceed the current 2GB limit before that happens.
