Acceptable Use Policy

Last updated: May 5, 2026

This Acceptable Use Policy ("AUP") sets out what you may and may not do when using What Changed? (the "Service"). It is part of our Terms of Service. We may update it from time to time.

1. Permitted use

The Service is designed to help you monitor publicly accessible web pages — for example competitor pricing, marketing pages, status pages, and documentation — and receive notifications when meaningful changes occur.

2. Prohibited content and targets

You must not use the Service to monitor or capture:

  • Pages that require authentication, bypass paywalls, or that you are not authorised to access.
  • Content that is illegal, infringing, defamatory, harassing, or that exploits minors.
  • Personal data of individuals where you do not have a lawful basis to process it (including stalking or surveillance of individuals).
  • Pages whose terms of service or robots directives expressly prohibit automated access by third-party tools, unless you have permission.

3. Prohibited behaviour

  • Do not attempt to overload, disrupt, or degrade any third-party website (e.g. by configuring abusive check frequencies).
  • Do not use the Service to send spam, phishing, malware, or unsolicited marketing.
  • Do not reverse engineer, scrape, or attempt to extract our source code, models, or non-public APIs.
  • Do not probe, scan, or test the vulnerability of the Service or circumvent any security or rate-limiting mechanism.
  • Do not resell, sublicense, or expose the Service as a generic web-scraping API to third parties.
  • Do not use the Service to build a competing product or to train machine learning models on captured content.

4. Reasonable use

Your use must stay within the limits of your plan. We may apply fair use limits to fetch frequency, page size, screenshot storage, and notification volume to protect the Service and the sites we fetch from.

5. Reporting abuse

If you believe someone is using the Service in violation of this AUP, or if you operate a site you would like us to stop monitoring, contact abuse@whatchanged.app.

6. Enforcement

Violations may result in throttling, suspension, or termination of your account, removal of offending configurations, and — where appropriate — referral to law enforcement. We may take action without prior notice where necessary to protect the Service, our users, or third parties.
