Giles Bowkett emphasizes the importance of picking tools that have export formats in his Time Management for Alpha Geeks video. I can’t agree more. Web connected make my data available most everywhere I go, but I get nervous when I can’t back up with a local copy. Web services come, and web services go.
I have used Don’t Break The Chain for 9 months. It tracks 9 different habits for me, and I hope it continues to run for a very long time. To ensure that I will never lose my data regardless of DBTC’s continued operation, I wrote an export script. It logs in to the service and outputs chain data as a CSV. It will optionally export to JSON as well.
