I used hook.io in its early days. It once lost the data in its internal data store when they were doing a database migration, rendering my hooks useless until I manually intervened. Haven't really used it much longer after that, but due to not needing it anymore.
Creator of hook.io checking in. Sorry to hear you had an issue.
We haven't had any recorded incidents of lost data. We did have an issue after a security upgrade where older accounts did need to be migrated with new access tokens. If you lost any data drop me an email and I'd be glad to find it.
The internal datastore is mostly for development purposes. We generally recommend persisting data to an external database like DynamoDB.
