Privacy Policy
Last Updated: July 3, 2026
This Privacy Policy describes how the SN-Viz Chrome Extension ("the Extension", "we", "us") handles your data. SN-Viz is a browser-based analytics and dashboard tool for ServiceNow professionals. It runs entirely in your browser and communicates only with your own ServiceNow instance.
Plain English Summary
1. What We Collect
SN-Viz does not collect any data about you or your usage. The following categories of data are processed only locally in your browser and are never transmitted anywhere outside it:
| Data Category | Purpose | Stored Where | Transmitted |
|---|---|---|---|
| ServiceNow instance URL(s) | Identify which instance to connect to; populate instance dropdown | Browser localStorage | Never |
| Dashboard layouts & saved dashboards | Save and restore user-created panel layouts and queries | Browser localStorage | Never |
| Theme preference (dark / light) | Persist the user's display preference | Browser localStorage | Never |
| DSL query strings you type | Execute visualisation queries against your ServiceNow instance | In-memory only (not persisted unless saved to a dashboard) | Sent only to your own ServiceNow instance |
| ServiceNow aggregate API responses | Render charts and tables in the dashboard | In-memory only; never written to disk | Never to any third party |
We do not collect:
- Personal information (name, email, address, phone number)
- ServiceNow record content, ticket data, or field values beyond what the aggregate API returns
- Authentication credentials, session tokens, or cookies
- Browsing history or URLs outside ServiceNow pages
- Keystroke logs, mouse movements, or interaction events
- Device identifiers or IP addresses
- Any information from users who are children under 16
2. Local Storage
SN-Viz stores the following items in your browser's localStorage. This data never leaves your device:
| Key | Contents |
|---|---|
| snviz_instances | List of ServiceNow instance base URLs you have used with SN-Viz (e.g. https://yourcompany.service-now.com) |
| snviz_theme | Your chosen colour theme: dark or light |
| snviz_autosave | Auto-saved state of the last open dashboard (panel positions, queries) |
| snviz_dashboards | Named dashboards you have explicitly saved |
All localStorage data is stored in your browser and can be cleared at any time from your browser's site data settings. Uninstalling the extension removes all extension-specific storage.
3. ServiceNow API Calls
When you run a query, SN-Viz makes HTTPS requests directly to your own ServiceNow instance using the ServiceNow Aggregate REST API (/api/now/stats/<table>). These requests:
- Use your existing authenticated browser session — no additional credentials are captured or stored by SN-Viz
- Travel directly from your browser to your ServiceNow instance — they do not pass through any SN-Viz server or proxy
- Return only aggregate statistical data (counts, averages, sums) — never individual record content unless you drill down, which opens the native ServiceNow list view in your browser
- Are subject to your ServiceNow instance's own access control, role permissions, and data governance
4. No External Servers
In its current form, SN-Viz operates with no backend server. The extension:
- Does not have a cloud service, API server, or data pipeline in its current free version
- Does not make any network requests to any domain other than your configured ServiceNow instance and Google Fonts (for UI typography, CSS only — no data is sent)
- Does not use analytics SDKs, error-reporting services, advertising networks, or tracking pixels
- Does not transmit usage data or telemetry to any server
If paid features are introduced in a future version, this section will be updated to accurately reflect any additional network communication required (e.g. licence verification). Any such update will be notified in advance per Section 8.
5. Extension Permissions
SN-Viz requests the following Chrome extension permissions. Here is what each is used for:
| Permission | Why It Is Needed |
|---|---|
| Access to your ServiceNow instance origin | Required to inject the /viz trigger into ServiceNow list views and to make authenticated API calls to the Aggregate REST API on your behalf |
| Storage (localStorage) | To persist dashboard layouts, saved queries, instance URLs, and theme preference locally in your browser |
| Scripting / activeTab | To read the current ServiceNow list view context (table name and active filter) when you type /viz, so SN-Viz can pre-populate the dashboard with relevant data |
SN-Viz does not request access to your full browsing history, bookmarks, file system, camera, microphone, or any other sensitive capability.
6. Chrome Web Store Data Disclosures
Chrome Web Store requires publishers to declare categories of user data their extension handles. The following table maps the Store's categories to SN-Viz's actual behaviour:
| Chrome Web Store Category | SN-Viz Behaviour |
|---|---|
| Personally identifiable information | Not collected |
| Health information | Not collected |
| Financial and payment information | Not collected |
| Authentication information (passwords, credentials) | Not collected |
| Personal communications (email, SMS, chat) | Not collected |
| Location data | Not collected |
| Web history | Not collected |
| Website content | SN-Viz reads the current ServiceNow list view URL/context locally when you trigger /viz. This data is used only to pre-fill the dashboard and is never transmitted outside your browser. |
| User activity (clicks, keystrokes, mouse movement) | Not collected |
SN-Viz does not sell, rent, or share any user data with third parties. In the current free version of the extension, there are no third-party sub-processors. If paid features are introduced (e.g. payment processing), any sub-processors involved will be disclosed in an updated version of this policy.
7. Children's Privacy
SN-Viz is designed exclusively for professional use by adults in enterprise or IT environments. We do not knowingly collect any information from individuals under the age of 16. If you believe a child has used this extension, no data is retained by us and there is nothing to delete from our systems.
8. Changes to This Policy
We may update this Privacy Policy to reflect changes in the extension's functionality. Material changes will be noted in the extension's Chrome Web Store listing and, where possible, in the release notes. The "Last Updated" date at the top of this page will always reflect the most recent revision. Continued use of the extension after a policy update constitutes acceptance of the revised terms.
9. Contact
SN-Viz is an independent, free extension. If you have questions or concerns about this Privacy Policy or the extension's data handling, you can raise an issue via the Chrome Web Store listing page.
