Third-Party Services

External Integrations

SEO WRITING SUPPORT does not directly integrate with third-party services. However:

• Search Engines: The extension accesses Google and Yahoo search results (public data)

• Disable Extension: Uninstall the extension to remove all stored data
• No Account Required: No registration means no personal data is tied to you

Children's Privacy
