Short version: SSR Checker does not collect, store, transmit, or share any personal data, browsing data, or user information — ever. Everything the extension does happens entirely within your browser.
What this extension does
SSR Checker is a developer tool that compares the live rendered HTML of a webpage against the version crawled by Google Search Console to surface server-side rendering discrepancies that could affect SEO.
All analysis is performed locally in your browser. No data is sent to our servers at any point during this process.
02 — Data Collection
No data is collected
SSR Checker does not collect, log, or transmit any of the following:
— URLs or domains you visit
— Page HTML or content
— Personal information of any kind
— Usage analytics or telemetry
— Crash reports or diagnostic data
We have no database, no analytics pipeline, and no backend that receives information from the extension.
03 — Local Storage
What stays on your device
The extension may use chrome.storage.local to store your preferences (such as display settings or last-used configuration). This data:
— Never leaves your device
— Is never transmitted to any server
— Can be cleared at any time via Chrome’s extension settings
04 — Permissions
Why each permission is needed
activeTab
Read the rendered HTML of the tab you’re inspecting — only when you invoke the extension.
scripting
Inject a script to extract the live DOM for comparison. No data is sent externally.
storage
Save your preferences locally on your device only.
sidePanel
Display findings in Chrome’s side panel alongside the page you’re inspecting.
webNavigation
Detect page navigation to reset the comparison state for the new URL.
declarativeNetRequest
Modify request headers to simulate how a crawler fetches pages for accurate SSR analysis.
05 — Third Parties
No third-party sharing
We do not share, sell, rent, or disclose any data to third parties — because we don’t collect any data to share in the first place.
06 — Changes
Policy updates
If this policy ever changes — for example, if a future version of the extension introduces optional analytics — this page will be updated and the “last updated” date will reflect the change. We will not introduce data collection silently.
