Merit Lab Privacy Policy

Last updated: October 6, 2026

Merit Lab version 1 is a local-first study app for SAT, PSAT, ACT, AP and CLEP topic practice. It has no sign-in, cloud sync, AI service or ads. The iOS app may offer an optional, one-time Practice Toolkit purchase through Apple's App Store for custom practice controls across the courses included in this version. The free study features do not require a purchase.

Web version. The web version has no sign-in or cloud sync. Profile and progress stay in the browser where you use Merit Lab. Export or reset this local data from Profile.

What stays on your device. Your profile (first name, birth year, goals, test date, topics you enjoy, companion), your answers, per-course practice and guide progress, streak, badges, and settings are stored on your device, protected by iOS data protection or the browser's local storage. There are no ads, third-party analytics SDKs, or trackers.

Optional anonymous usage sharing (web and iOS). If a first-party analytics service is configured, eligible learners may opt in under Profile → Usage & feedback. After consent and age eligibility, the app sends a separate random install identifier and limited product interaction events such as session completion and experiment exposure. It does not send names, email, birth year, account IDs, question or answer text, or feedback notes. This information is not linked to an account and is not used for tracking. Sharing is off by default; turning it off clears the local queue and identifier. Events expire within 30 days. If the service is not configured, events remain on device.

Your birth year. We ask for it once, during setup, only to decide which features are available. It stays on your device. If you may be under 13, optional usage sharing is unavailable. You may still choose to share a duel, assignment, or progress link; those links contain the information described below.

Accounts and cloud sync are not enabled in version 1. AI features are not enabled in version 1.

Links you choose to share.

• Duel links you share contain your first name (if set), your companion, question IDs, your score, time taken, and which questions were correct.
• Assignment links contain the assignment and teacher names, skills, question count, and due date.
• Progress receipts you share with a teacher contain your first name and practice statistics (questions answered and correct by skill, estimated score range, streak). They contain no answers and no question content.

Session feedback. The optional session feedback form is saved on this device. It is not an App Store rating prompt and does not submit feedback to Merit Lab. You can export or clear it under Profile → Usage & feedback.

Question reports. Choosing “Report this question” opens a form. Nothing is sent until you choose Send report. The report sends the question's source, course, ID and content version, your selected reason, an optional note, the app platform and a random report ID to Merit Lab's first-party service hosted by Cloudflare. It does not send your profile, answers or usage-sharing identifier. Do not include personal information in your note. Reports are used to investigate question and explanation issues and are deleted within 90 days. Temporary daily salted network identifiers are used to limit abuse; IP addresses are not saved in report records. Cancel closes the form without sending it. Hiding a SAT question on your device is a separate local action.

App Store purchases (iOS). Apple handles payment and billing information. Merit Lab uses Apple's StoreKit on your device to verify ownership, restore purchases and respond to refunds or revocations. Merit Lab does not receive your payment-card information or send purchase receipts to its own server. A purchase does not transfer browser progress or unlock a web account.

Widgets and notifications (iOS). The streak widget reads a small summary stored on your device. Reminders are scheduled on your device; no push service is used.

Children. Merit Lab is intended for students preparing for college admission tests. It is not directed to children under 13. Optional usage sharing is disabled for learners who may be under 13.

Your control. Export or reset local data from Profile. Turning optional usage sharing off clears its local queue and identifier. Deleting the app removes its on-device copy.
