# HMIC Permissions [Data access](broken://pages/-MUTOkL4DRYvKgDzGqTa), reading *or* writing data, in a PDA must be permitted through contracts set up by Dataswyft, between application owners and their users who are the server owners on Dataswyft’s infrastructure. When an application is ready to go live with on PDAs, the application owner will need to request for contracts to be set up and so that the application owner has the correct legal access to the PDAs of their users when users sign up. The mechanism of asking permission from the user is a special contract called a HAT Microserver Instructions Contract (HMIC). This is a special contract for permission to “rent space“ for storage in the server database for the application to deposit data. Dataswyft’s role is to set up these contracts for access as part of the data account terms of service. All applications, by default, have read-update-delete access to their specified [namespace](/learn/personal-data-account/namespaces.md)(s). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
