Privacy Policy: Developer Page Inspector
Effective date: 3 October 2026

SUMMARY
Developer Page Inspector is local-first. Pages you inspect or audit are analysed inside your browser. There is no account, no analytics, no telemetry, no advertising, and no server of ours that receives page data. We do not sell or share user data, and we do not use it for anything other than the features you use.

PERMISSIONS AND WHY THEY ARE NEEDED
- activeTab, scripting: when you open the add-on on a tab, it reads that page's DOM and styles to inspect elements, run the audit, draw overlays (box model, focus order, rulers) and capture screenshots. Nothing runs on pages you don't open it on.
- storage: settings, rule preferences, notes and snapshots, stored locally (extension storage and IndexedDB).
- contextMenus, alarms: adds "Inspect element" / "Audit this page" to the right-click menu, and re-checks a Pro license once or twice a day.
- Access to websites (optional): never granted at install. Requested for the sites a tool needs, when you use it: keeping a tool working after the page reloads, batch audits, link and hreflang checks, asset ZIP, the responsive viewer. Revocable in Settings > Permissions.
- cookies (optional): only for the Cookie editor, only for the current site, after you click "Allow". Values are masked until you reveal them. The add-on never stores or sends them on its own.
- downloads (optional): only for "Download all" in the asset inventory.
- browsingData (optional): only for "Clear site data", after a confirmation, for the current site.
- webRequest (optional): only while you use "HTTP status & redirects" or record "Marketing tags" for one tab. Read-only: nothing is blocked, stored or sent.
- userScripts (optional): only for "Site snippets": CSS/HTML/JavaScript you write yourself runs on the site you chose. Nothing is downloaded from us.
- api.lemonsqueezy.com: activate and validate a Pro license key.

DATA STORED ON YOUR DEVICE
- Snapshots you save: audit findings, page metadata, colors, fonts, asset URLs, detected technologies and, if you choose, a downscaled screenshot.
- Notes on elements, rule settings, custom rules, ignored findings, checklist progress and color-picker history.
- Design overlay images you upload, site snippets you write, the last header-editor rows, and your own PageSpeed Insights API key if you add one.
- Onboarding and rating-prompt state (dates and counters only), and Free-plan daily counters (audits, Pro passes).
- If you buy Pro: the license key, activation instance id, plan and last validation time.
- If you arrived through an affiliate link: the affiliate code, so the referral is credited at checkout.
Storage, IndexedDB and cookie values of the pages you inspect are shown to you only and are not saved by the add-on. Exports redact secret-looking values by default.

DATA SENT OFF YOUR DEVICE
Only in these cases, and only when you use the feature:
1. License (Pro only): the license key, the activation instance id and an instance name made of the browser name and major version are sent to Lemon Squeezy, our payment provider and merchant of record. Checkout, subscription management (including cancelling auto-renew) and the affiliate program run on Lemon Squeezy's own pages; the add-on never sees card details.
2. Feedback you choose to send: the feedback form sends only what you type (and your email, if you enter it) to Tally, which hosts the form. Nothing about the inspected page is included.
3. Lighthouse: "Run" in SEO > Lighthouse sends the page URL (and your own API key, if you added one) to Google PageSpeed Insights, which loads the public page and returns scores.
4. Requests to the sites themselves: the audit asks the inspected site for its own robots.txt, sitemap.xml, llms.txt and response headers. "Check links", the hreflang checker, "ZIP" and "Optimize images" request the linked pages and files directly from your browser, without cookies.
Page content, findings, screenshots and everything else listed above are never sent anywhere by the add-on.

RETENTION AND DELETION
Data stays until you delete it. Settings > Delete all local data erases snapshots, notes, overlays and settings (your license stays until you deactivate it). Removing the add-on removes everything.
