Privacy Policy for Shumway SEO Toolkit
Effective date: June 8, 2026
Shumway SEO Toolkit is an extension for on-page SEO inspection. It is designed to be private, local, and lightweight.
Data The Extension Handles
Shumway SEO Toolkit reads website content from the active browser tab only when you open or use the extension.
This may include SEO-related page data such as:
Page title and meta description
Current URL and canonical URL
Headings
Links
Images and image attributes
Structured data, including JSON-LD, Microdata, and RDFa
Open Graph and X/Twitter metadata
Robots meta and X-Robots-Tag information
Fonts, colors, CSS variables, and stylesheets
Lightweight browser performance signals where available
This data is used only to display on-page SEO information, provide copy tools, and generate local exports.
Data Collection
Shumway SEO Toolkit does not collect, store, sell, transmit, or share user data.
The extension does not use:
Analytics
Tracking pixels
Remote logging
Advertising identifiers
User accounts
Background crawling
Third-party data collection APIs
Local Processing
All page analysis happens locally in the user’s browser.
Exports such as CSV, TSV, JSON, Markdown, and image ZIP files are generated locally from the current page. Exported files are saved only when the user chooses to download them.
External Links And Third-Party Sites
Some buttons open external websites, such as Google Search Console, Bing Webmaster Tools, Ahrefs, Archive.org, Moz, Semrush, Similarweb, Schema Validator, Rich Results Test, Buy Me a Coffee, PayPal, Venmo, or cryptocurrency wallet links.
These sites are opened only when the user clicks the relevant button. Shumway SEO Toolkit does not send data to these services in the background.
Any information entered into or shared with those third-party sites is governed by their own privacy policies.
Payments And Donations
Optional donation links may open third-party payment services. Shumway SEO Toolkit does not process payments, collect payment information, or store donation details.
Permissions
Shumway SEO Toolkit requests permissions only to support its stated SEO functionality, such as reading the active tab when used, opening context-menu actions, generating downloads, and optionally toggling site JavaScript settings when requested by the user.
Data Sharing
Shumway SEO Toolkit does not share user data with the developer, advertisers, analytics providers, data brokers, or any other third parties.
Limited Use Disclosure
The use of information received from browser APIs will adhere to the Web Store User Data Policy, including the Limited Use requirements.
Children’s Privacy
Shumway SEO Toolkit is not directed to children and does not knowingly collect personal information from children.
Changes To This Policy
This privacy policy may be updated if the extension’s functionality or data handling changes. Any updates will be posted on this page with a revised effective date.
