SEO Check by Rhillane

Privacy policy

Last updated: October 27, 2026. Applies to version 1.7 and later.

SEO Check is a browser extension published by Rhillane Marketing Digital. It shows SEO information about the web page you are viewing. This policy explains what data the extension handles. In short: Rhillane collects nothing about you, and optional features contact Google or Open PageRank only when you use them.

What the extension reads

When you open SEO Check, it reads the page in your current tab: its title, meta tags, headings, images, links, Open Graph and Twitter tags, structured data (JSON-LD, Microdata, RDFa), visible text, page load timings and the names and versions of libraries the page uses. It also lists email addresses, phone numbers and social profile links shown on that page.

In the popup this happens only after you click the icon. If you dock SEO Check in the side panel, it reads the active tab each time you switch tabs or a page finishes loading, until you close the panel.

Everything it reads is processed in your browser and shown to you. The contact details it lists stay on your device unless you export them to a CSV file yourself.

Changes on the page

When you click Highlight or the locate button, the extension adds temporary outlines and labels to headings, images or links and scrolls to them. It does not change page content, and the highlights disappear when you clear them or reload the page.

Requests the extension makes

  • To the website you are analyzing: its public robots.txt, sitemap.xml and llms.txt files and the page’s HTML source.
  • When you click Check broken links, Check file sizes or Check return tags: the links, images or alternate language pages found on that page.
  • When you click Scan the whole site: up to 50 pages of that same website (from its sitemap and its own links), then up to 250 of the links found on them. Pages are read without cookies and the scan stops when you click Stop or close the extension.
  • When you run a PageSpeed test: the page URL is sent to the Google PageSpeed Insights API.
  • When you use Google position: the extension opens a Google search for your keyword and location in a background tab of your browser, reads the organic results, then closes the tab (it stays open if Google asks you to solve a captcha). It is a normal Google search made from your browser, so Google’s own terms and privacy policy apply to it.
  • When you add an Open PageRank key: the domain name of the page is sent to the Open PageRank API to get its authority score.

Requests to the analyzed website are sent without cookies.

Optional AI features (Google Gemini)

The AI Assistant is off until you add your own Gemini API key in Settings. When you run an AI audit, ask a question or write an article, the extension sends the following to the Google Gemini API, using your key:

  • the page URL, title, meta description and headings
  • an excerpt of the page’s visible text (up to about 6,000 characters)
  • the scores and issues SEO Check detected
  • your question, or the outline, keyword and tone you entered for an article

This data goes straight from your browser to Google, not to Rhillane. Google processes it under its own terms: the Gemini API Additional Terms of Service and the Google Privacy Policy. Do not use the AI features on pages that show private or confidential information.

What is stored on your device

  • Settings (chrome.storage.local): your Gemini, PageSpeed and Open PageRank API keys if you entered them, the AI model and the answer language. Delete the keys at any time with Remove keys in Settings, or by uninstalling the extension.
  • Display preferences: the last section opened, Simple or Expert view, and whether you closed the welcome tip, so the extension reopens the way you left it.
  • Target keywords: the keyword you type for a page, saved with that page’s address so it is still there next time. It stays on your device and is never sent anywhere.
  • Score history: for each page you check with SEO Check, its address, title, the date, its scores and the list of problems found, and the same for whole-site scans. It is kept on your device so the Progress screen can show how your scores change over time. It is never sent anywhere. You can turn it off, forget one page, or clear all of it in Settings and on the Progress screen. The extension keeps at most 20 results per page and removes the oldest pages when it reaches its storage limit.
  • Last scan (chrome.storage.session), only so it can be shown as a printable report. It is cleared when you close the browser.
  • Whole-site scan results (chrome.storage.session): the pages read for the website you scanned, so you can see the results again or continue an interrupted scan. They are cleared when you close the browser.

None of this leaves your device, except each API key, which is sent only to the service it belongs to with the requests you make.

What the extension does not do

  • It does not send any data to Rhillane Marketing Digital. Rhillane has no server for this extension.
  • It does not collect personal information about you, such as your name, email, location or account details.
  • It does not record the pages you browse. With score history on, it remembers only the pages you check with SEO Check, on your device, and never sends that list anywhere.
  • It does not use cookies, analytics or advertising tools.
  • It does not sell, share or transfer any data.

Clipboard and downloads

When you click a copy button, the extension writes text to your clipboard. It never reads your clipboard. CSV, Markdown and PDF exports are saved by your browser as normal downloads.

Third-party services

The fonts (Poppins and Inter) are packaged inside the extension, so opening it makes no request to Google Fonts or any other font service. Links in the More tools, Rich results and Built with sections open external services such as Google PageSpeed Insights, the Rich Results Test, Similarweb or BuiltWith in a new tab, only when you click them. Those services have their own privacy policies.

Permissions

  • activeTab and scripting: read the SEO data of the page you analyze, add highlights when you ask, and read Google results for Rank check.
  • storage: save your settings and the last scan on your device.
  • sidePanel: let you dock SEO Check beside the page.
  • Access to websites: make the requests listed above, follow the active tab in the side panel, and reach the Google Gemini, PageSpeed and Open PageRank APIs.

Changes

If this policy changes, the new version will be published on this page with an updated date.
