Privacy

• We collect what's needed to watch pages and send you alerts, and nothing to sell. No ads, ever.
• No tracking cookies and no third-party scripts. The only cookie keeps you logged in.
• We count visits ourselves, without cookies and without storing your IP address.
• You can download everything or delete your account from Settings at any time. Deletion is immediate.

• Your account: email address, a one-way hash of your password (we can't read it), your timezone, and your email settings.
• Your monitors: the URLs you add, the part of the page you watch, the text of the last 10 versions of each page, and the last 200 checks with what changed.
• Your channels: Slack, Discord and webhook URLs, encrypted. We only ever show you a shortened form of them.
• Alert receipts: when each alert was sent and whether it arrived, for 30 days.
• Sessions: a login record for each browser you use, for up to 30 days.

One cookie, which keeps you logged in. It's set when you log in, it can't be read by scripts, and it's removed when you log out or after 30 days. Because it's strictly necessary and we use no others, there's no cookie banner.

When a page of ChangePing loads, we record the page (without anything after a ?), the site that linked you here or a campaign tag like ?ref=, whether you're on a phone, tablet or computer, and sometimes your country.

To count unique visitors, we combine your IP address and browser name with that day's date and a secret key, and keep only a short scrambled code. The code changes every day, so a visit today can't be linked to one tomorrow, and the IP address itself is never saved.

We also note account events, such as signing up or adding a monitor, to see where people get stuck. These records are deleted after 13 months. When you delete your account, they stay only as anonymous totals that no longer point to you.

Our checker visits the URLs you add, identifying itself as ChangePing. It reads only the public text of the page, the same as anyone visiting it. Please only watch pages you're allowed to view.

We use a few providers to run ChangePing. They process data only on our behalf:

• Railway: runs the app.
• Neon: hosts the database.
• Google Workspace: delivers our emails.
• OpenAI: writes the short brief at the top of each change alert. It receives the changed lines of the page, with the page's name and address, and nothing about your account.
• Cloudflare: answers DNS lookups for changeping.com.

If you connect Slack, Discord or your own webhook, we send each alert, including the changed text, to that address. From there it's handled by that service. We don't sell or share your data with anyone else, and we'd only hand it over if the law required it.

Your account data stays until you delete your account. Deleting it removes your monitors, page versions, channels and sessions straight away. A copy may survive in database backups for a short time before those expire. Server logs, which record page paths and errors but no query strings or passwords, are kept only as long as our hosting provider holds logs, usually a few days to weeks.

• See or take your data: Settings, Account, Download your data.
• Delete everything: Settings, Account, Delete account.
• Stop emails: the link at the bottom of every alert, or Settings, Notifications.
• Anything else, including correcting data or asking what we hold: email us, and we'll reply within 30 days.

If we change this policy in a way that matters, we'll email you before it takes effect. Questions go to [email protected].
