Privacy Policy

Last updated: 1 July 2026

The short version: PrepOK does not require an account and does not ask you for personal information to use the site. We use Google Analytics to understand how the site is used, and Google AdSense to display ads; both rely on cookies. Where the law requires it, we ask for your consent first, and you can always control cookies through your browser and the options below.

Who we are

This Privacy Policy applies to the PrepOK website at prepok.com ("PrepOK", "we", "us", "our"), operated by QuantumLoops Technologies. If you have any questions about this policy or your data, contact us at support@prepok.com.

Information we collect

PrepOK has no logins, no user accounts, and no checkout. We collect very little:

Cookies and similar technologies

Cookies are small files stored by your browser. PrepOK uses two kinds: analytics cookies (to measure usage) and advertising cookies (to show and, where permitted, personalize ads). You can block or delete cookies in your browser settings at any time; some site features may work differently without them. Where required (for example for visitors in the European Economic Area, the United Kingdom, and Switzerland), we ask for your consent through a cookie banner before non-essential cookies are set.

Analytics

We use Google Analytics to understand which lessons are useful and how the site performs. Google Analytics sets cookies and processes usage data on our behalf. You can learn more in Google's Privacy Policy, and you can opt out across all sites with the Google Analytics Opt-out Browser Add-on.

Advertising

PrepOK is supported by ads served through Google AdSense. To keep the site free, we display advertising on our lesson and reference pages (never inside the embeddable widgets on other people's sites). Some key points:

Your choices and rights

Depending on where you live, you may have rights over your personal data. Under the GDPR (EEA/UK) these include the right to access, correct, delete, or object to processing of your data, and to withdraw consent. Under the CCPA/CPRA (California) they include the right to know, to delete, and to opt out of the "sale" or "sharing" of personal information for targeted advertising. We do not sell your personal information for money. To exercise any right, email us at support@prepok.com, and use the ad and cookie controls above. We honour recognized browser signals such as Global Privacy Control where applicable.

Children's privacy

PrepOK is intended for teachers, parents, and students, and is not directed to children under 13. We do not knowingly collect personal information from children under 13 (or the minimum age in your country). If you believe a child has provided us personal information, contact us at support@prepok.com and we will delete it.

Service providers and third parties

We rely on a small set of trusted providers to run PrepOK, including Google (Analytics and AdSense) and Vercel (website hosting and content delivery). These providers may process data in countries other than your own; where that happens, appropriate safeguards apply. We do not sell your personal information.

Data retention and security

Analytics data is retained according to our provider's settings, and emails are kept only as long as needed to handle your request. We take reasonable technical and organizational measures to protect data, though no method of transmission or storage is completely secure.

Links to other sites

Our lessons cite and link to external sources. We are not responsible for the privacy practices of those sites; please review their policies.

Changes to this policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date above. Significant changes will be made clear on this page.
