This Cookie Policy explains how MACPrep uses cookies and similar browser storage technologies. We keep this minimal: we use only what is needed to run the Service and do not use third-party advertising or cross-site tracking cookies.
| Technology | Purpose | Type |
|---|---|---|
| Secure session cookies | Keep you signed in without exposing long-lived credentials to page scripts. | Strictly necessary |
Local storage (macprep_signed_in) | Stores a non-secret sign-in indicator so public navigation can show the Dashboard link. | Strictly necessary |
| Session storage | Stores a non-secret active-tab marker. Authentication credentials remain in HttpOnly cookies and cannot be read by page scripts. | Strictly necessary |
| Local storage (preferences and local state) | Remembers interface preferences, theme and font choices, and resumable local product state. It does not hold your authentication credential. | Functional |
Local storage (macprep_analytics_consent) | Remembers whether you allow or decline optional first party analytics, so the site can honor your choice. It stays in your browser until you change your choice or clear site data. | Analytics choice |
Local storage (macprep_vid) | After you allow analytics, assigns a pseudonymous first party identifier to measure use of the public sample question experience. It is not used for cross site tracking. | Optional analytics |
Local storage (macprep_marketing_attribution_v1) | After you allow analytics, stores limited campaign, partner, and referral tokens from tagged visits to understand how people find MACPrep. | Optional analytics |
Browser attribution is used for up to 90 days after the most recent tagged visit. An expired local record may remain in browser storage until it is replaced or you clear site data. Campaign attribution may also be linked to your MACPrep account when you sign up, sign in, or make a purchase. Account-linked records are stored separately; the 90-day browser limit is not an account-data retention period. See our Privacy Policy for account-data retention.
Signing out clears the active MACPrep session. Closing a tab clears its session storage. Clearing site data for macprep.org removes cookies, preferences, local state, and the public-demo identifier and will sign you out.
Optional first party interaction events run only after you allow them. Declining does not affect sign in, studying, purchases, or any other core feature. You can change your choice below at any time.
We may update this policy; the "last updated" date reflects the latest version.
