You can generate and export a backup of your data in Structured. To learn how to do this, check out: How to Reset & Backup Your Structured. Additionally, we plan to add a CSV file export.
It is not possible to export tasks or events from Structured into a different calendar app. Currently, you can only import tasks from your calendar app into Structured, although we are working on a solution that makes the synchronization of events in both directions possible.
For more information on features that we are working on right now, check out the Structured Roadmap. If you are interested, you can sign up to receive updates on our current projects.
