What OnPageWatch does

OnPageWatch is a browser extension and service that monitors the public, on-page SEO elements of web pages you choose to watch (title tags, meta tags, headings, canonical links, structured data) and notifies you when they change.

Data we collect

• Account data: your email address and a hashed password.
• Watch data: the URLs you choose to monitor and snapshots of those pages' public SEO fields.
• Billing data: subscriptions are processed by Paddle.com, our Merchant of Record. We never see or store your card details. Paddle shares with us your email, subscription status, plan and renewal date. See Paddle's privacy policy.
• Technical logs: standard server logs (IP address, request time) kept briefly for security and debugging.

Cookies

The marketing site sets no tracking or advertising cookies. The extension stores your session token locally in your browser's extension storage. The admin area uses a session cookie strictly for sign-in.

What we do not collect

• We do not track your browsing history. The extension only reads the URL of your current tab when you explicitly click "Watch this page".
• We do not sell or share your data with third parties for advertising.
• We do not inject content into, read, or modify the pages you visit.

AI processing

When a watched page changes, a structured summary of the changed SEO fields (not the full page, and nothing about you) is sent to Anthropic's API to generate a plain-English alert. See Anthropic's privacy policy.

Data retention and deletion

Snapshots are pruned automatically (we keep roughly the last twelve per watched page). Deleting a watched page deletes its snapshots and change history. To delete your account and all associated data, email us and we will action it within 30 days.

Your rights

You may request a copy of the personal data we hold about you, ask us to correct it, or ask us to delete it entirely. Email us from your account address and we will respond within 30 days. You may also complain to your local data protection authority.

Changes to this policy

If we make material changes we will announce them in the extension or by email before they take effect.
