Privacy Policy

Effective Date: September 8, 2025

Last Updated: June 23, 2026

Welcome to Qol, operated by Qol Inc, a Delaware corporation ("Qol", "we", "our", or "us"). This Privacy Policy explains how we collect, use, and protect information when you use our website, mobile and web applications, and related services (the "Service"). By using Qol, you agree to the terms of this Privacy Policy. If you do not agree, please do not use the Service.

1. Who We Are

Qol provides AI-powered language tutoring designed to help users improve speaking confidence and real-world conversation skills through voice-based interaction. If you have questions, contact us at support@useqol.com.

2. Information We Collect

We collect information necessary to provide, improve, and secure the Service.

a. Account Information

When you create or use an account, we may collect your email address, authentication information, account identifiers, language preferences, onboarding choices, learning goals, account settings, and support communications.

b. Voice, Speech, and Learning Data

When you use voice features, your audio input is processed to generate AI tutor responses. Speech may be converted into text transcripts, analyzed to produce feedback and scores, and used to update your vocabulary, learning progress, session history, and practice plan.

We may store session transcripts, user utterance audio, tutor replay audio, tutor audio paths, vocabulary records, learning state, usage limits, streak information, and session results to operate and improve the Service.

AI-generated responses and feedback are produced automatically and may not always be accurate.

This data may be processed by trusted providers including OpenAI. Session data may be stored using Supabase to support learning progress.

c. Usage Data

We may collect information about how you interact with the Service, including device type, operating system, browser or app version, IP address, pages or screens viewed, button taps, session duration, performance diagnostics, error logs, and feature usage.

d. Payment Data

Payments are processed by Stripe, RevenueCat, the Apple App Store, or Google Play. Qol does not store full payment card details. We may store subscription status, plan tier, renewal state, customer identifiers, receipt or entitlement metadata, and billing events needed to provide paid features.

e. Cookies and Analytics

We use cookies, local storage, analytics, and diagnostics tools to provide sign-in, measure product performance, understand feature use, detect errors, improve reliability, and protect the Service.

f. Notifications

Qol currently supports local scheduled reminders on your device. These reminders may use Expo and platform notification APIs from Apple or Google, but we do not currently collect a remote push token for these reminders. If we later enable remote push notifications, we may collect a device push token and will use it only for reminders, streak updates, account messages, or similar Service-related notifications.

5. Data Retention

We retain personal information only as long as reasonably necessary to provide the Service, maintain learning progress, meet legal or tax obligations, resolve disputes, enforce agreements, prevent abuse, and maintain security.

Learning progress, transcripts, vocabulary history, session metadata, and stored audio may remain in your account until you delete history, reset progress, delete your account, or request deletion. Some limited records may be retained where required for billing, legal compliance, fraud prevention, backup integrity, or security.

6. Access, Export, and Account Deletion

You may access and export available account, billing summary, session, vocabulary, and usage information through the Service where supported.

You may delete learning history, reset progress, or delete your account within the Qol mobile or web application. Account deletion is intended to remove your account data, learning progress, stored session data, transcripts, and stored audio, except where retention is required for legal, billing, backup, fraud-prevention, or security purposes.

If you cannot access your account, contact support@useqol.com.

7. Data Security

We use administrative, technical, and organizational safeguards designed to protect your data, including account authentication, access controls, provider security controls, and private storage for session data. No system is completely secure, and we cannot guarantee absolute security.

8. Your Rights

You may access, correct, or delete your data, and opt out of notifications through your device settings. Depending on where you live, you may also have rights to request access, correction, deletion, portability, restriction, or information about how we use and share your personal information.

For California residents, these rights may include the right to know the categories of personal information we collect, use, and disclose; the right to request deletion or correction; the right to opt out of sale or sharing; the right to limit certain uses of sensitive personal information where applicable; and the right not to be discriminated against for exercising privacy rights. Qol does not sell personal data.

9. International Data Transfers

Data may be processed in the United States or other jurisdictions where our providers operate.

10. Children's Privacy

Qol is not intended for children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided personal information to Qol, contact us so we can take appropriate action.

11. Changes to This Policy

We may update this Privacy Policy periodically. When we make material changes, we will update the "Last Updated" date and may provide additional notice where appropriate. Continued use means acceptance.
