Privacy Policy
Last updated: August 28, 2026
This Privacy Policy explains how Quizzar Go ("we", "us", or "our") collects, uses, protects, and discloses your information when you use our mobile application (the "Service"). By accessing or using the Service, you consent to the data practices described in this policy.
1. Information We Collect
Account Information
- Google Sign-in: If you authenticate via Google, we collect your name, email address, and profile picture associated with your Google account.
- Email Sign-up: We collect your email address and generate a default display name (which can be edited).
- Guest Mode (Ages 13+): An anonymous account identifier is created to synchronize session progress locally and across the device. No personal identifiable information is attached.
- Guest Mode (Under 13): No account is created, and all data processing remains strictly local to the device (see Section 6).
User-Generated Content
- Vault Content: Quizzes and generated content you choose to save are stored securely in our database and linked to your account.
- Chat Data: Interactions with AI chat and defend features are stored locally on your device. We do not transmit or store chat histories on our servers.
- Uploaded Assets: Documents and images uploaded for quiz generation are transmitted to our AI provider (Google Gemini) strictly for real-time processing. These assets are not retained by our servers post-generation.
Usage and Technical Data
- Token balances, generation history, subscription status, and purchase records.
- Application telemetry required for basic functionality, rate limiting, and fraud prevention.
Advertising Data
- If you interact with advertisements, our ad provider (Google AdMob) may collect device identifiers (such as Android Ad ID), IP addresses, and app interaction metrics to deliver ads and verify reward claims. This data collection is restricted for users who indicate they are under 13.
2. How We Use Your Information
We process the collected data to:
- Provide, operate, and maintain the core features of the Service (e.g., cross-device synchronization).
- Manage user accounts, subscriptions, and AI generation balances.
- Monitor for and prevent abusive activity, fraud, and unauthorized usage.
- Serve advertisements and verify rewarded ad interactions.
We do not sell your personal data to third parties.
3. Advertising
Quizzar Go utilizes Google AdMob to display advertisements, including optional rewarded ads. Data collection for advertising is governed by Google’s privacy practices.
- Age-Based Restrictions: We enforce Google’s tag for child-directed treatment (TFCD) and tag for users under the age of consent (TFUA). Users under 13 are served non-personalized, contextual advertisements exclusively.
- Consent and Control: In compliance with GDPR, UK GDPR, and relevant US state laws, users in applicable jurisdictions are presented with a consent dialog via the Google User Messaging Platform (UMP). You may review, grant, or withdraw consent for personalized advertising at any time via Settings → Privacy Choices.

- Local Data: Chat histories are deleted immediately upon uninstalling the application or clearing local app data.
- Account Deletion: You may delete your account within the app via Settings → Delete Account or by emailing us. Upon initiation, your profile, avatar, saved content, and telemetry are immediately purged from active production databases. Encrypted backups containing snapshot data naturally expire and are destroyed within 30 days.
- Legal Retention Exceptions: To comply with tax laws, accounting standards, and fraud prevention obligations, an anonymized snapshot of your financial transaction history (and the email address at the time of purchase) is retained permanently.
9. International Data Transfers
Our service providers, including Supabase and Google, operate globally. Your information may be transferred to, stored, or processed in the United States or other locations outside of your resident jurisdiction. By utilizing Quizzar Go, you consent to these international data transfers under applicable standard contractual clauses.
10. Security
We implement robust technical and organizational security measures—including encrypted transit (HTTPS), secure local storage, and Row-Level Security (RLS) policies within our database—to protect your data against unauthorized access, alteration, or destruction. However, no internet-based service can guarantee absolute security.
11. Changes to This Policy
We reserve the right to update this Privacy Policy periodically. If material changes are made concerning how we handle your personal data, we will notify you via a prominent in-app alert and update the "Last updated" date at the top of this document.
