Data retention policy
We retain only the minimum data required to operate ApproveFlow.
Expense request records (amount, description, status, timestamps, user IDs) are stored for the purpose of tracking request history and usage per workspace.
We do not store any Slack messages, user profile information, or channel content.
All data is retained for as long as the workspace is actively using the app. Upon uninstalling ApproveFlow, all associated data is automatically deleted within 30 days.
Workspace administrators can request immediate deletion of data at any time by contacting us at support@approveflow.io.
Data archiving and removal policy
When a workspace uninstalls ApproveFlow, all related data (expense requests, user references, and metadata) is flagged for deletion.
We automatically delete all workspace-related data within 30 days of uninstallation.
We do not archive any data after removal.
Workspace administrators may also request immediate deletion of all data by emailing support@approveflow.io.
