I had hoped to update this thread with more specific information for others interested in this topic, however technical support seems to be dodging my question. Technical support said that TCH does weekly updates, but no matter how I word the question, they have not given me a straight answer as to how long it will take for archived deleted data to be rotated through the backup cycle so that it is gone for good (as Bruce mentioned).
I just wanted to know how the data I upload to TCH is treated (in all aspects, but in this case specifically upon being deleted). As an example, Google recognized the need to inform everyone that they would only hold onto their data for 18 months. They did this to be up front with their users. Overall I've had a really good experience with TCH, so I thought TCH would take the same proactive approach in regards to having set standards for the handling of their customer data. Judging from the lack of a straight answer from technical support, it seems TCH does not. This is disappointing.
I understand that upon deleting an account, the data from that account will "eventually" be gone for good. But, I was looking for a more specific answer to my question. If anyone has any more information in regards to this topic, please post.
Thanks!
