Tabhound Privacy Policy

Last Updated: November 9, 2026

This Privacy Policy explains how the «Auto Refresh & Page Change Monitor - Tabhound» (Tabhound) browser extension ("we", "us", "our") handles information when you use the extension (the "Service").

The short version: the pages you watch never leave your device. Tabhound reads the text of a watched tab only to check the condition you set, and it does that locally in your browser. We never see, upload or store the pages you watch, their addresses, or the words you watch for. We collect only anonymous usage statistics to improve the product.

Our Principles

• Privacy policies should be human-readable and accurate.
• We collect the minimum needed to improve the product.
• The pages you watch are yours: every check runs locally in your browser.

Information We Do NOT Collect

• The content of the pages you watch, their addresses (URLs) or titles, the text you tell Tabhound to look for, the area you pick, or the text that matched. All of it is processed on your device and is never uploaded to any server.
• Your name, email address, account credentials, or payment information: the extension requires no account.
• Your browsing history. Tabhound only accesses tabs you explicitly start watching, on sites you grant access to.

How Tabhound Uses Page Access

Tabhound asks for access to one website at a time, when you press "Start watching" or "Pick an area" on that site. With that access it:

• reloads the watched tab on the interval you chose;
• reads the text of the page (or of the area you picked) after each load to check whether your text appeared, disappeared, or the area changed;
• outlines the match on the page and marks the tab title when your condition is met.

This happens only in tabs you started watching. You can remove a site's access at any time in Chrome's extension settings.

Information We Collect

Anonymous Usage Analytics

To understand how the extension is used and to improve it, we collect anonymous usage statistics via PostHog (PostHog Inc., USA), an analytics provider. This includes:

• A randomly generated anonymous identifier stored in your browser. It is not linked to your identity and contains no personal details.
• Product events: watch started (mode, interval, whether "randomize" and "don't reload" are on, whole page or picked area, how many watches are running), match found (mode, number of checks, minutes watched), watch stopped (reason, number of checks, minutes watched), alert stopped (seconds until you stopped the sound), permission denied, and area picker used. We never send page content, URLs, page titles, or the text you watch for, only these counts and categories.
• Cumulative usage statistics computed on your device: the total number of watches you have started and the most watches you have run at the same time, and your plan type (free or paid), attached to the anonymous identifier.
• Technical information: browser type and version, operating system, device type, and browser language, derived from your browser's user-agent string.
• Approximate location (country/city level) and time zone, derived by PostHog from your IP address when events are received. We do not collect precise location.
• Anonymous error reports (technical stack traces from the extension's own code, with any web addresses removed) to help us fix bugs. No page content is included in error reports.

Locally Stored Data

The extension stores data in your browser's own extension storage. It stays on your device:

• Settings (local storage): alert sound, volume, "bring tab to front on alert", and your last-used refresh interval and randomize choice. Removed when you uninstall the extension.
• Active watches (session storage, with a backup copy in local storage so running watches survive an extension update): for each watched tab, its address and title, your interval and condition, the picked area, check counts, and a short excerpt of the matched text so the popup can show it. This is cleared when you stop the watch or close the tab; the backup is cleared the next time Chrome starts.

Chrome Web Store Limited Use

Tabhound's use of information received from Chrome APIs adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements.

How We Use Information

We use the collected information to: understand which features are used and improve the product; diagnose and fix errors; and analyze aggregate usage trends.

We do not sell your information. We do not use it for advertising. We do not combine it with data from other sources to identify you.

Who We Share Information With

• PostHog Inc. (USA): processes the anonymous analytics described above on our behalf. PostHog's privacy policy: https://posthog.com/privacy
• Legal requirements: we may disclose information if required to do so by law or valid legal process.

Your Choices and Rights

• Stopping data collection: analytics are an integral part of the Service. If you do not wish usage statistics to be collected, you can stop using and uninstall the extension: no data is collected when it is not installed. Locally stored data is removed on uninstall.
• Site access: you can remove Tabhound's access to any website in Chrome's extension settings; watching on that site stops.
• EEA/UK rights: subject to applicable law, you may request access to, correction of, or deletion of data, object to or restrict processing, and lodge a complaint with your supervisory authority. Because our analytics identifier is anonymous and not linked to your identity, we generally cannot single out which stored analytics relate to you.
• To exercise these rights, email [email protected].

International Transfers

Analytics data is processed on PostHog's servers in the United States. Where required, we rely on appropriate safeguards for such transfers in accordance with applicable data protection law.

Data Retention

Anonymous analytics are retained only as long as needed for the purposes above. Settings remain on your device until you clear them or uninstall the extension; active-watch data is cleared when the watch ends, and its backup copy the next time Chrome starts.

Security

Analytics data is transmitted over encrypted connections (HTTPS). Since the pages you watch never leave your device, the most sensitive data is protected by not being transmitted at all.

Children

The Service is not directed at children under 13 (or under 16 where GDPR applies). We do not knowingly collect personal information from children; the analytics we collect is anonymous for all users.

Changes to This Policy

We may update this Policy as the Service evolves. We will post changes on this page and update the "Last Updated" date above. Material changes will be highlighted as required by law.
