Cookie Policy
NDTAcademy.com, LLC
Effective Date: September 23, 2026
1. Overview
NDT Academy uses cookies and browser storage for account access, checkout continuity, preferences, and campaign attribution. We also use Vercel Web Analytics and Speed Insights for visitor and performance measurements, our own purchase diagnostics to understand where checkout problems occur, and the Google Ads tag to measure whether our ads lead to signups and purchases. These measurements do not collect your full card number, CVC, or bank credentials; Stripe handles payment details.
2. Cookies and Browser Storage
| Name | Purpose | Storage |
|---|---|---|
sb-*-auth-token (Supabase) | Keeps you signed in; required for account features. | Strictly necessary · session/refresh lifetime |
ndta-cookie-notice | Remembers that you dismissed the cookie notice so we don’t show it again (stored in your browser’s local storage). | Local storage; hides the notice for 12 months |
ndta.checkout.attempt:* | Connects checkout retries to your selected product. | Session storage |
ndta_purchase_flow | A random identifier linking purchase-page visits, course choices, authentication steps, and checkout events. Diagnostics include broad browser/device categories and product or checkout identifiers; signed-in events may be associated with your account. | First-party cookie renewed for 30 minutes of activity and session storage; optional purchase diagnostics |
ndta_funnel_event:* | Prevents repeated page renders or retries from counting the same purchase step more than once. | Session storage; optional purchase diagnostics |
| Campaign attribution | Remembers campaign parameters from links so we can understand how people reach signup and courses. | Cookies, session storage, and local storage |
_gcl_* (Google Ads) | Set by the Google Ads tag to record whether a visit from a Google ad led to a signup, checkout start, or purchase. Ad personalization is off, so it is not used for remarketing. | First-party cookies set by Google, up to 90 days; not loaded under Do Not Track or Global Privacy Control |
ndta_ads_conversion:* | Prevents a reloaded order page from reporting the same purchase to Google Ads twice. | Session storage; advertising measurement |
3. Third-Party Cookies During Specific Flows
Stripe supports checkout, payment processing, and fraud prevention. Persona operates the identity-verification widget. These providers may use their own cookies and storage when their services load. Vercel provides the website analytics and performance measurements described above. Google provides the advertising conversion measurement described above; see how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites.
4. Your Choices
You can block or delete cookies in your browser settings; blocking the authentication cookie will sign you out and prevent account features from working. You can also clear browser storage. Our optional browser-based purchase diagnostics and the Google Ads tag do not load or send tracking events when your browser signals Do Not Track or Global Privacy Control. Essential server-side payment, enrollment, and security records continue to operate. Dismissing the notice only hides the notice; it does not change these browser settings.
