Summary
What A320Q uses
- Stripe processes payments; full card details do not pass through A320Q.
- Account email, password hash and subscription identifiers support login and Premium access.
- Premium members may choose an optional first name or nickname for their invitation page. Showing it is off by default; when enabled, anyone with the invitation link can see that chosen name. The setting can be changed or removed on the Invite a Friend page. The name is not added to product analytics, and a referred subscriber's identity is not shown to the member. Eligible new members who sign in to a verified account through an invitation can choose 97 days for CHF 29 without automatic renewal, or Monthly at CHF 13.50 for the first month, then CHF 15/month until cancelled. Previous paid accounts are checked using account and billing history; the offer is applied once and cannot be stacked with other discounts.
- Short-lived verification and password-reset tokens may be stored when those features are used.
- A320Q learning history stores a question identifier, category, result, quiz mode and time. Selected-answer text is not stored in that history.
- A320Q records a limited set of first-party product events using internal account IDs or hashed pseudonymous browser identifiers to measure quiz, account and subscription journeys. This includes server-confirmed checkout creation, same-browser return from a cancelled checkout, and Premium activation. Landing measurement uses only coarse source, device class and entry-page categories; it does not store full referrer URLs or arbitrary query values. If you arrive through a member's invite link, the random link code is stored with that visit. The valid code is also saved with the server-side referral and checkout record so financial attribution does not depend on browser analytics. Pre-checkout referral attribution normally expires after 30 days; checkout and reward records retain the evidence needed for billing and reconciliation. If your first eligible Premium purchase passes 14-day payment validation, the inviting member can earn CHF 3 towards future Monthly bills or 14 extra pass days, according to their plan when your checkout opens. Existing reward promises retain their terms. The member is not told who you are. Refunded or disputed purchases do not qualify and related credit or extra days may be reversed. Product-event properties do not include raw email, answer text, reset or claim tokens, Checkout Session IDs, or raw Stripe identifiers.
- Product events are normally retained for up to 400 days. Anonymous learning attempts that are not linked to an account are normally removed after 90 days; authenticated learning history remains with the account so progress can be reviewed.
Page measurement
Google Ads page views
A Google Ads tag is used on some A320Q pages to record page views. When that tag loads, Google may receive page, browser and network information. The password-reset page does not load the tag.
