Effective November 3, 2026.
ChangeSpot stores selected page text, page URLs, element fingerprints, titles, baselines, observed values and change history locally in your Chrome profile. Page content is not sent to our servers, used for AI, or sold. There is no advertising or analytics.
Site access is optional and requested for each site you choose. Chrome notifications are optional. We do not read input values, passwords, cookies or browser authentication tokens. Only open pages are checked. Delete watches to remove their local data; uninstalling removes extension storage.
If you buy PRO, Stripe processes payment and purchase contact details under Stripe's policy. Our Cloudflare service stores payment references, hashed license identifiers, revocation status and temporary purchase claim hashes. Short-lived rate-limit counters use keyed IP hashes. License verification sends your license key and a random installation identifier over HTTPS; it never sends your tracked pages or their content.
The local license key stays in extension storage and may be included in a backup you explicitly download. Keep it private. Purchase claims expire after 30 days; rate-limit counters after 48 hours; payment/license records remain for purchase verification and revocation. Contact support for deletion requests; deleting license records ends PRO access.
