PageChange

About

See what changed — without alerts, accounts, or tracking.

PageChange shows you what changed on a web page since the last time you visited it.

No monitoring.
No email alerts.
No accounts.
No data leaves your browser.

How it works

1. Enable PageChange on a site you care about.
2. Visit the page once to save a snapshot.
3. When you return, PageChange shows:
   - Which sections changed
   - What text was added
   - What text was removed
4. Optionally filter to “Show only changed” sections.

Everything happens locally in your browser.

Privacy by design

- Page content is stored locally using Chrome’s storage API.
- No data is transmitted to any server.
- No analytics, tracking, or telemetry.
- The extension runs only on sites you explicitly enable.
- You can delete stored data at any time.

Useful for

- Release notes
- Pricing pages
- Policies and terms
- Product documentation
- Vendor updates
- Any page you revisit and want clarity on

Permissions

PageChange uses minimal permissions:

- storage — to store page snapshots locally.
- scripting — to inject the badge and change viewer on sites you enable.
- activeTab — to enable the extension for the current site when you click “Enable”.
- optional host permissions — the extension runs only on sites you choose.
