Privacy Policy for Query Result Viewer for BigQuery

Last updated: August 23, 2026

Query Result Viewer for BigQuery is a Chrome extension that makes BigQuery Query Results easier to read, including results containing long text, JSON, ARRAY, and STRUCT values.

Data the extension handles

When a user selects Open in Viewer from the BigQuery Export menu, the extension activates BigQuery's Copy to clipboard action and reads the copied table data from the clipboard. The copied result may contain data supplied by or visible to the user.

The extension accesses clipboard data only to open copied BigQuery Query Results in the Viewer and to copy values explicitly selected by the user from the Viewer.

How data is used and retained

Copied query data is processed locally in the user's Chrome browser. It is placed temporarily in chrome.storage.session so the BigQuery page can pass it to a new Viewer tab. The Viewer removes the temporary entry when it reads the data. If the Viewer does not read it, an alarm removes it after approximately 10 minutes.

The extension does not intentionally persist BigQuery query data after this temporary transfer. View settings exist only in the open Viewer page and are not synchronized or persistently stored by the extension.

Data sharing and external services

The extension:

• does not send copied BigQuery data to the developer or any external server;
• does not send copied BigQuery data to external APIs;
• does not sell or transfer user data to third parties;
• does not use remote code;
• does not collect analytics, advertising data, or usage telemetry; and
• does not use user data for personalized advertising, creditworthiness, lending, or any purpose unrelated to displaying and copying query results.

No developer or third party is given access to read the user's copied query data through this extension.

Chrome permissions

• clipboardRead: reads the query result produced by BigQuery's Copy to clipboard action after the user chooses Open in Viewer.
• clipboardWrite: copies values selected by the user in the Viewer.
• storage: temporarily transfers copied data to the Viewer using Chrome session storage.
• alarms: removes temporary session data if it has not already been consumed by the Viewer.

The extension runs its BigQuery integration only on https://console.cloud.google.com/bigquery*.

Limited Use

Use of information received from Chrome APIs adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements. Data is used only to provide the extension's single, user-facing purpose: displaying and copying BigQuery Query Results in a readable Viewer.

Changes

If the extension's data practices change, this policy and the Chrome Web Store disclosures will be updated before those changes are released.
