Ask HN: Best aggregation tool for personal data

I recently saw this website: https://ahmetalpbalkan.com where Ahmet has aggregated all his personal data. Is there any tool you guys have seen that aggregates this information easily? My ideal app would be just connecting my accounts and it presents this information easily to me.

I think personal data is a very interesting subject and is more beneficial to see what you are doing and how you can better improve yourself.
