Tableau Public vs Private Data Workflows: Sharing or Keeping Dashboards Internal
Tableau Public is built for public data. Published views and underlying data can be accessible and downloadable, and a hidden viz can still be reached by URL. Use this checklist before uploading sensitive metrics.
Tableau Public is for data that can be shared on the internet, not for confidential customer, sales, or personal data. The official FAQ says published workbooks and underlying data are not private by default, a hidden viz can still be seen by someone with its URL, and Public uses extracts rather than live connections.
| Item | Tableau Public | Private data workflow |
|---|---|---|
| Access | Published vizzes are intended for internet access | Controlled by organizational products and permissions |
| Downloads | Workbook and underlying data are downloadable by default; settings can disable them | Governed by policy and permissions |
| Hidden state | Can hide a viz from a profile, but a known URL can still work | Authentication, authorization, and audit are the boundary |
| Connections | Extracted data only; Google Sheets can refresh under a specific condition | Live or controlled connections depend on the product |

First ask whether a stranger may download the data
That is the shortest decision path. If a column contains customer identity, an unreleased sales plan, personal finance, contract pricing, or internal credentials, treat it as unsuitable for Tableau Public. A public link, a hidden profile, and a disabled download button are not a replacement for data classification.
Public research, government open data, approved product metrics, and teaching samples can fit Public. Even then, check for internal flags, row-level records, or fields that could identify a person when combined. A clean-looking chart does not prove that the underlying extract is clean.
Published workbooks and data are visible by default
The Tableau Public FAQ says workbooks and data published to a profile are not private and can be accessed on the internet. The default Download link may expose the workbook and underlying data. You can turn off downloads in viz settings, but that removes an entry point; it does not turn Public into private storage.
Downloadability can be useful for a public project because readers can inspect, learn from, and reuse the structure. For a client report, it expands the distribution surface and may expose detail behind a single trend. Decide whether sharing is the product goal before you publish.
