Privacy Policy
TrailsBI collects nothing about you or your reports. The tool and the visual run on your computer and inside Power BI, and send nothing to us or anyone else.
This policy covers the trailsbi command line tool, the TrailsBI visual for Power BI and this website, trailsbi.com.
The trailsbi tool
- Runs on your computer. It reads the metadata files of a Power BI project (PBIP): model and report definitions. It never opens
cache.abfor any imported data. - Makes no network calls and has no telemetry, analytics or usage statistics.
- Writes the HTML report only where you choose. It changes your project only when you run
--embed, which adds a hidden table,TrailsBI, to your semantic model, and a hidden TrailsBI page with the TrailsBI visual to your report.
The TrailsBI visual
- Runs inside Power BI's sandbox for custom visuals. It reads only the field you add to it: the Chunk column of the TrailsBI table.
- Makes no network calls and sends nothing to TrailsBI or anyone else. It asks Power BI for no web access.
- A link in the visual opens only when you click it, and Power BI asks you first.
- The TrailsBI table holds your model's table, column and measure names, DAX and data source addresses. It lives in your semantic model under your organization's Power BI settings and permissions. Anyone who can open the report can read it in the visual.
This website
- No cookies, analytics, advertising or tracking scripts. Fonts and images are served from this site.
- If you switch to dark mode, that choice is saved in your browser's local storage, on your device only.
- The site is hosted on GitHub Pages. GitHub logs visitors' IP addresses for security purposes; see GitHub Pages data collection and the GitHub Privacy Statement.
