SalesQL Browser Extension Notice

v1.2Updated 14 May 2026Effective 7 May 2026

This Notice describes how the SalesQL browser extension (the “Extension”) processes data. It supplements the SalesQL Privacy Policy, the Terms of Service and the Acceptable Use Policy (AUP), each of which apply when you install or use the Extension.

The Extension is provided by SALESQL LTD, a private limited company registered in England and Wales under company number 11982774, with registered office at 71-75 Shelton Street, London, WC2H 9JQ, United Kingdom.

#1. What the Extension does

The Extension is a tool that End Users install in their own browser to operate alongside their authenticated session on supported professional networking sites. While you are browsing a profile, search results page or other supported page through your own logged-in account, the Extension can:

  • Read the professional information rendered on the page (full name, current and past job titles, current and past employers, employment dates, education, skills, certifications, languages, professional summary, the public profile URL and avatar, and other professional fields visible on the profile).
  • Display SalesQL UI inside the page (a sidebar or overlay) showing enriched contact data, “save to list” actions, and quick-action shortcuts to the SalesQL workspace.
  • Make outbound network requests to the SalesQL backend on your behalf to enrich, save, export or look up the contact you are viewing.

The Extension operates as a tool that allows you to act on data already accessible to you through your own authenticated session on the supported site. It does not log in on your behalf, does not bypass any technical access controls of the supported site, and does not extract data from accounts you are not authorised to access.

#2. Where the Extension is active

The Extension is scoped to operate only on a defined set of supported professional networking sites. It does not run on personal email providers, on banking or finance sites, on consumer websites, or on internal corporate sites.

The current list of supported sites, together with any surfaces or subsections within those sites where the Extension is not enabled, is set out in the Extension’s listing on the Chrome Web Store, the Firefox Add-ons marketplace and other browser stores from which the Extension is distributed. The browser store listings are the operational source of truth for the Extension’s scope and are updated as supported sites evolve.

The Extension activates on supported pages after they have finished loading.

#3. Categories of data processed

While you use the Extension on a supported page, the Extension processes:

  • Professional information rendered on the page (the full set described in Section 1 above).
  • The URL of the page being viewed, used to associate enrichment requests with the correct profile.
  • Your SalesQL account identifier and authentication state, to ensure that you are entitled to use the Extension’s features.
  • The Extension version, browser type and operating system, for compatibility, debugging and bug reporting.

The Extension does not process:

  • The content of pages on domains it is not scoped to.
  • Content from third-party sites you are browsing in other tabs.
  • Data from accounts other than the supported-site account through which you are authenticated.

#4. The Contributor Program

When you use the Extension on a supported professional networking site, the professional information visible on the profiles you view is also used by SalesQL to maintain the freshness, accuracy and quality of the SalesQL Profiles Database for the benefit of all SalesQL Customers. For example, when the Extension observes that a professional has changed employer, that observation contributes to the freshness of the underlying record.

This is described in the Privacy Policy and in the Contributor Program Terms. Use of the Extension constitutes participation in the SalesQL Contributor Program. The legal basis for SalesQL’s processing of professional contact information through the Contributor Program is legitimate interests under Article 6(1)(f) UK/EU GDPR, supported by a documented Legitimate Interests Assessment and Data Protection Impact Assessment.

We maintain source, freshness, verification and confidence metadata internally to support the quality of the Profiles Database and the handling of data-subject rights. We do not disclose, to other Customers, the specific End User, workspace or signal that contributed to a given data point.

If you do not wish to participate in the Contributor Program, do not install or use the Extension. The rest of the SalesQL Services (the web application, the REST API, and the MCP Server) remain available without participation in the Contributor Program.

Business Contacts whose data is in the Profiles Database can exercise their rights, including the unconditional right to be removed, through the SalesQL Privacy Center.

#5. Local storage on your device

The Extension uses the browser’s local storage to keep:

  • Authentication tokens that link the Extension to your SalesQL account. These tokens follow the same session lifetime as the SalesQL web application. They are stored in the browser’s localStorage; the tokens are scoped, revocable, and do not provide any access beyond what you have on the SalesQL web application.
  • Lightweight feature preferences to remember your in-Extension UI state.

When you uninstall the Extension, the local storage associated with the Extension is removed by the browser. You can also clear the Extension’s local storage through your browser’s site-data settings at any time.

If you have specific concerns about the security of token storage in browser extensions, please contact security@salesql.com.

#6. Telemetry

The Extension sends usage telemetry to Segment (operated by Twilio Inc.), which we use as our product-analytics processor. The telemetry consists of events describing your interactions with the Extension’s user interface — for example, which buttons you click, when the sidebar is opened, and which features you use. The telemetry includes your SalesQL account identifier (so that we can attribute usage to the correct Account) and high-level metadata such as Extension version, browser and operating system. The telemetry does not include the names, email addresses, phone numbers or other professional details of the profiles you view.

We rely on legitimate interests as the legal basis under Article 6(1)(f) UK/EU GDPR for this processing — namely the legitimate interest in operating, debugging, securing and improving the Extension. End Users who do not wish their interactions with the Extension to generate telemetry can uninstall the Extension; the rest of the Services do not depend on the Extension’s telemetry.

Segment is listed on the SalesQL Subprocessors page.

#7. Permissions and architecture

The Extension is distributed through the Chrome Web Store, the Firefox Add-ons marketplace and other official browser stores. Its manifest requests only the browser permissions necessary to operate on the supported professional networking sites identified in the Extension’s store listing. Within those sites, the Extension reads the rendered DOM, injects its own UI elements, and makes outbound network requests to the SalesQL backend on your behalf.

The Extension does not request:

  • Access to sites other than those identified in its store listing.
  • Browsing history beyond the URL of the active page when the Extension is invoked.
  • Access to your other tabs.
  • Access to system-level resources (clipboard read of arbitrary content, microphone, camera, location, notifications) beyond what is strictly required for the Extension UI.

The Extension is updated through the official browser store under its standard auto-update mechanism. Each update is reviewed by the store before being made available.

#8. Relationship with third-party site terms

The terms of service of the third-party site on which the Extension operates govern your use of that site. You are responsible for ensuring that your use of the Extension complies with the third-party site’s terms. SalesQL is not a partner of any third-party site on which the Extension operates, and the Extension is not an official product of any such site. The Extension does not bypass any third-party site’s authentication, anti-bot or rate-limiting mechanisms, does not access the site’s API endpoints under SalesQL’s credentials, and does not read content that is not rendered to your own logged-in session.

#9. Onboarding and consent

When you first open the Extension, you are required to accept the SalesQL Terms of Service, which (i) describe your responsibilities as a SalesQL End User, (ii) describe the Contributor Program participation that is structural to using the Extension (Section 4 above), and (iii) point you to this Notice and to the Privacy Policy.

The descriptions of the Extension that appear in the Chrome Web Store, Firefox Add-ons and other browser stores are constrained by the platforms’ own listing requirements and contain the most up-to-date description of the Extension’s permissions and supported sites. For the complete description of how the Extension processes data, please rely on this Notice together with the Privacy Policy and the relevant browser store listing.

#10. Removal and your rights

You can uninstall the Extension at any time through your browser’s extension management settings. Uninstalling the Extension stops further data processing through the Extension, and the browser removes its associated local storage.

If you are a Business Contact whose data may have entered the Profiles Database through Extension observations and you wish to be removed from the Profiles Database, please use the SalesQL Privacy Center — the public, self-service form for opt-out and data-subject rights requests, with verification by email. The Privacy Policy (Section 11) describes the suppression process in detail.
