Treefold Privacy and Data
Last updated: October 6, 2026
Bacumi.com does not collect your project data through this free extension. The extension processes data in your browser and communicates with your Azure DevOps organization to perform its functions.
Data used by the extension
Query definitions and results, work item fields (which may include names and other personal data), hierarchy links, and selected rich-text content are read from Azure DevOps. Excel workbooks are generated in your browser and downloaded to your device; they are not uploaded to Bacumi.com.
Permissions and sign-in
vso.work: Read-only access to work items and queries. Treefold does not modify work items.
The Azure DevOps SDK supplies a session access token for requests to your organization. It is not sent to Bacumi.com. No separate Bacumi.com account or personal access token is required.
What Bacumi.com does not collect
There is no Bacumi.com backend for this free extension, no usage analytics, advertising tracking or automatic crash reporting. The extension does not upload project content, credentials or exports to Bacumi.com, sell that data, or use it for model training.
Storage and retention
Per-user preferences are saved in your organization’s Azure DevOps extension data storage: query identifiers and column layouts (up to 50 saved layouts), hierarchy mode, rich-text and text-wrap choices, a successful-export counter, and review-prompt dismissal or snooze state. The counter controls the review invitation; it is not transmitted to Bacumi.com as telemetry.
Downloaded workbooks remain wherever you save or share them until you delete them. Clearing browser data does not remove preferences held by Azure DevOps. Ask your organization administrator about managing extension data; its retention and removal follow Azure DevOps controls. Uninstalling is not a guarantee that exports or preferences are erased.
Your organization and Microsoft
Your organization determines how its Azure DevOps data is used and retained. Microsoft hosts Azure DevOps, Marketplace assets and related services, and may process service logs and network information under its own arrangements. Profile images can load from the URLs supplied by Azure DevOps. This notice does not claim that Microsoft collects no data or that every network request stays inside your browser.
See the Microsoft Privacy Statement. For access or deletion requests concerning project data, contact your Azure DevOps organization administrator.
Support and privacy requests
If you email support or use the website contact form, we receive the information you choose to send. That separate processing is covered by the Bacumi.com Privacy Policy, including your rights, retention and contact details. Please redact confidential and personal information from screenshots and error messages.
