Chrome Extension
Privacy Policy
This page explains how the CheckLink.ai Chrome Extension handles data when you use browser shortcuts to open CheckLink tools.
Effective date: July 13, 2026
Last updated: July 13, 2026
The CheckLink.ai Chrome Extension is operated for the CheckLink.ai website. For privacy questions, contact hello@navines.com.
The extension has a single purpose: user-triggered access to CheckLink link-safety tools and explicit checks of the current page, selected links, selected URL/domain text, or pasted URLs.
Data Handled by the Extension
Current active-tab URL, only after you choose Check page, the keyboard shortcut, or a current-page context action.
A hyperlink URL, selected URL/domain, or pasted URL, only after you choose a CheckLink action.
Favorite tool IDs stored locally for the popup.
Recently used tool IDs and timestamps stored locally for the popup.
Basic local interface preferences, such as collapsed categories.
Tool/action identifiers and UTM referral values such as chrome_extension, extension, and tool action names.
Standard HTTP request information processed by hosting infrastructure, which may include IP address, user agent, request time, and requested path.
Local Chrome Storage
Favorites, recent tools, and popup preferences are stored in chrome.storage.local. Checked URLs and scan results are not stored in Chrome extension storage.
favoriteToolIds
Favorite CheckLink tool IDs selected in the popup.
recentTools
Recently used tool IDs and timestamps.
collapsedCategories
Local popup category display preferences.
You can remove this local data by using the extension's Clear button for recent tools, changing favorites in the popup, clearing extension site data in Chrome, or removing the extension.
Data Not Accessed
No webpage body text, except a selected URL or domain only when you explicitly use the selected-text context menu.
No images, page screenshots, or file contents.
No form contents, passwords, authentication tokens, or cookies.
No personal communications or email bodies.
No complete browsing-history list.
No background monitoring and no automatic scanning.
No script injection or content scripts.
Use of Submitted URLs
When you choose to check a URL, the extension opens CheckLink with the URL in the browser fragment where supported. The CheckLink page reads that fragment client-side, clears it from the address bar, and waits for you to start the check. The URL is then sent to CheckLink's scanner only to provide the requested check or tool.
Submitted URLs are not used for personalized advertising, sold, used for creditworthiness or lending, or used for unrelated profiling.
Processors and Service Providers
Vercel hosts CheckLink.ai and may process extension-originated page requests, scanner requests, security logs, IP address, user agent, and request metadata as part of normal hosting and infrastructure operations.
Vercel Analytics is used on the website for aggregate page and event analytics. CheckLink analytics events should not include checked URLs, email headers, selected text, or scan result contents.
Resend is used only if you choose to submit a contact, report, or lead form on CheckLink.ai. Normal extension checks do not send email through Resend.
Google Chrome stores the extension's local data on your device through Chrome extension storage. CheckLink does not operate Chrome or the Chrome Web Store.
Retention
Extension local storage remains on your device until you clear it or remove the extension.
CheckLink does not keep an application database of extension scan history or checked URLs.
Hosting, security, and analytics logs are retained according to Vercel's service settings and CheckLink's operational needs for reliability, abuse prevention, debugging, and aggregate usage understanding.
If you submit a form, the submitted information may remain in owner email systems as long as needed to respond, review, protect the service, or keep business records.
Security and User Choices
Extension actions open HTTPS CheckLink.ai pages.
Permissions are limited to activeTab, contextMenus, and storage.
The extension has no host permissions, content scripts, or remote executable code.
You can clear recent tools, remove favorites, uninstall the extension, or contact CheckLink about privacy questions.
Chrome Web Store Limited Use
The use of information received through Chrome extension permissions complies with the Chrome Web Store User Data Policy, including the Limited Use requirements.
