What does Atlassian do with my wiki if/when I cancel my account?

[Lisa Williams]

If my Company decides to cancel our account and use of Confluence sometime in the future, what happens to the information we've captured?  

Can you provide a certificate of destruction as verification?

Hi @Lisa Williams and welcome to the community

Everything you need to know is described here https://support.atlassian.com/security-and-access-policies/docs/track-storage-and-move-data-across-products/

Data retention period

The length of your product’s data retention period will depend on its license or plan. For products with:

• Evaluation licenses – data is retained for 15 days

• Free plans - data is retained for 60 days

• Standard and Premium plans – data is retained for 60 days

At the end of this data retention period, your product’s data will be permanently deleted and cannot be recovered.

I don't think that link addresses whether Atlassian provides a certificate of destruction?
