CPO Study Hub is a free educational website. We've kept this policy as short and plain-spoken as we can. If anything is unclear, please get in touch.
The short version
- We don't ask you to sign up, log in, or give us any personal information.
- We use Google AdSense to display ads, which uses cookies to show you more relevant ads.
- We may use basic analytics to count visits and see which pages are popular.
- You can opt out of personalized ads using the tools linked below.
Information we collect
CPO Study Hub itself does not collect personally identifiable information. There are no accounts to create, and we do not ask for your name, email, or any other identifying details to use the practice tests, flashcards, or Pool School content. Your quiz progress and Pool School progress are stored locally on your own device using your browser's storage — we never see them.
Cookies and third-party services
Like most websites, ours uses cookies and similar technologies, primarily through third-party services that we use to keep this site free.
Google AdSense
We use Google AdSense to display advertisements. Google may use cookies (including the DoubleClick DART cookie) to serve ads based on your prior visits to this site and other websites on the internet. This helps Google show ads that are more likely to be relevant to you.
You can learn more about how Google uses information from its partner sites and apps at policies.google.com/technologies/partner-sites.
You have several options if you'd rather not see personalized ads:
- Manage your ad preferences at adssettings.google.com
- Opt out of personalized advertising from many networks at once at optout.aboutads.info and youronlinechoices.com
- Use your browser's "Do Not Track" setting or a privacy-focused browser extension
Third-party vendors, including Google, may also use cookies to serve ads based on a user's prior visits to our website. We don't have access to or control over cookies set by third parties.
Local browser storage
We use your browser's local storage to remember small things that improve your experience — for example, which Pool School sections you've completed, or your last quiz settings. This information stays on your device. We never collect or transmit it. You can clear it any time by clearing your browser's site data.
Web analytics
We may use a privacy-respecting web analytics tool to count visits, see which pages are popular, and understand roughly where our visitors come from. This information is aggregated and does not identify you personally.
Children's privacy
CPO Study Hub is intended for adults studying for a professional certification or learning about home pool care. We do not knowingly collect any information from children under 13. If you believe a child has provided information to us, please contact us so we can remove it.
Your rights
Depending on where you live, you may have specific rights over your personal information under laws like the EU's General Data Protection Regulation (GDPR) or the California Consumer Privacy Act (CCPA). Because we do not directly collect personal information, most of these rights are exercised through the third-party services described above — primarily Google, whose own privacy policy describes how to access, correct, or delete data Google holds about you.
External links
Our pages may link to external sites such as the CDC's Model Aquatic Health Code or the PHTA. We are not responsible for the privacy practices of those sites. We encourage you to read the privacy policy of any third-party website you visit.
Disclaimer about content
CPO Study Hub is an independent study and education resource. It is not a substitute for the official PHTA certification course, professional pool service, or local health regulations. Always verify chemistry decisions for your own pool, follow product label instructions, and consult a professional when in doubt.
Changes to this policy
We may update this privacy policy occasionally — for example, if we add a new analytics tool or change how ads are served. When we do, we'll update the "Last updated" date at the top of this page. Continued use of the site after changes constitutes acceptance of the new policy.
