PageChange

See what changed on a page since your last visit — private, local, and opt-in per site.

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. Current Version v0.1 — Core change detection with: - Per-site opt-in - Section-aware change display - Minor wording detection - “Show only changed” toggle
