ChangeSweep Privacy Policy

Last updated: November 12, 2026

ChangeSweep (“the extension”) is a Chrome extension that watches web pages you choose for text changes. This policy explains what data it handles. The short version: your monitors, snapshots, and page content stay on your device, and we don't collect, sell, or share your browsing data.

What the extension accesses

The current tab, when you use the toolbar icon or the element picker. ChangeSweep uses Chrome's activeTab and scripting permissions so it can read the page you're viewing after you click, and so it can highlight the region you pick.
Per-site access, only after you add a monitor. When you start watching a page, Chrome will ask you to grant access to that site. ChangeSweep uses that permission to re-check the page on the schedule you set (and only while Chrome is open). It does not request access to every site at install time.
Alarms, notifications, and local storage. Alarms schedule checks. Notifications tell you when something changed. Storage holds your monitor list, settings, and on-device change history.

What we store

Your monitors (name, address, selector, ignore rules, interval, and the latest snapshots and diffs) in Chrome's local extension storage on your device.
Your settings, including an optional webhook address if you provide one.

What we do NOT collect

We don't collect or transmit your browsing history, the pages you watch, or personal information to ChangeSweep servers. The extension has no analytics, no tracking, no ads, and no remote code. Checks run in your browser.

Optional webhooks

If you enter a webhook address (for example a Slack or Discord incoming webhook that you own), ChangeSweep will POST a change summary and the watched page's address to that address from your browser when a change is detected. We don't operate a relay. You can remove the webhook at any time in the dashboard.

Payments (Pro)

Pro isn't on sale yet, and the current version of ChangeSweep doesn't process payments or contact any payment service. When Pro launches, payments will be handled by a third-party payment provider, and this policy will be updated before that happens. Planned Pro features include 24/7 cloud checks and email alerts; those will involve sending the addresses you choose to watch to a server, and we'll describe that clearly first.

Waitlist and contact forms (website only)

If you join the waitlist or send a message through our contact form, we receive what you enter: your email address, your message, and any optional answers. We use it only to reply to you or to tell you about the Pro launch. Form submissions are delivered through a form-delivery service (FormSubmit, formsubmit.co), which processes them under its own privacy policy. You can ask us to delete your information at any time through the contact form.

Data sharing

We don't sell or share user data with third parties, except the form-delivery service described above and, if you opt in, the webhook endpoint you configure yourself. Our use of data follows the Chrome Web Store User Data Policy, including its Limited Use requirements.

Children

ChangeSweep is not directed at children under 13.

Changes

If this policy changes, we'll update the date above and post the new version here.
