Privacy Policy

Effective Date: October 17, 2026

We Are Somos ("Company", "we", "us", or "our") operates the Jubjub Korean mobile application (the "App"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our App. Please read this policy carefully.

1. Information We Collect

We collect the following information to register your account, provide the App, manage paid subscriptions, and offer customer support.

a. When you sign up (required)
  - Email address and password
  - If you sign in with Apple: the email address provided by Apple (or, if you choose to hide your email, Apple's private relay address) and your name. We do not collect your Apple account password.

b. Information generated and collected while you use the App
  - Video learning records: videos studied, completion counts, last studied date, learning stage
  - Word learning records: words studied, correct/incorrect answers, scheduled review dates, study dates
  - Your saved sentences

* We do not collect advertising identifiers (IDFA/ADID) and do not serve personalized advertising.

2. How We Use Your Information

We use the information we collect to:
- Provide, operate, and maintain the App and its features
- Manage user accounts and verify identity
- Manage paid subscriptions and verify purchase history (payment card details are handled directly by Google Play / Apple App Store and are not collected by us)
- Deliver personalized features such as video and word learning progress tracking and review scheduling
- Provide customer support and respond to inquiries
- Analyze usage of the App to fix errors and improve service quality

3. Children's Privacy

The App is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that a user is under 13, we will promptly delete their account and associated data.

4. Third-Party Service Providers (Data Processors)

We entrust the processing of personal data to the following service providers in order to operate the App. Our agreements with these providers require that your personal data be handled securely.

- Supabase, Inc. (United States)
  Purpose: user authentication and database hosting
  Data processed: account information, learning records

- RevenueCat, Inc. (United States)
  Purpose: subscription status management and receipt validation
  Data processed: app user identifier, purchase history

- PostHog, Inc. (United States / EU)
  Purpose: product usage analytics
  Data processed: app user identifier, app usage data, device information

- Apple Inc. / Google LLC (United States)
  Purpose: in-app payment processing
  Data processed: payment information such as purchase receipts (purchase tokens). We do not hold your card details.

Data entrusted to these providers is retained until you delete your account or our agreement with the provider ends.

5. International Data Transfers

To provide the App, we transfer personal data to the countries where the providers listed in Section 4 are located (the United States and the EU). The data transferred, and the timing and method of transfer, are as described in Section 4; data is transmitted over the internet at the time you use the App.
You may object to the international transfer of your personal data. However, if you do, you may be unable to sign up, save learning records, or use paid subscriptions.

6. Data Retention

As a rule, your personal data is deleted immediately upon account deletion. However, where retention is required by applicable law (such as consumer protection laws governing electronic commerce), we retain the relevant records for the period prescribed by that law (for example, records of payments and the supply of goods for 5 years).

7. Your Rights (Including GDPR)

Depending on your location, you may have the following rights regarding your personal data:

- Right of Access: Request a copy of the personal data we hold about you.
- Right to Rectification: Request correction of inaccurate data.
- Right to Erasure: Request deletion of your personal data ("right to be forgotten").
- Right to Restriction: Request that we limit the processing of your data.
- Right to Data Portability: Request your data in a portable format.
- Right to Object: Object to processing based on legitimate interests or for direct marketing.

To exercise any of these rights, you may:
- Delete your account and personal data immediately via the App (Profile → Delete Account)
- Contact us at contact@wearesomos.com

We will act on your request without undue delay, and may decline a request where we have legitimate grounds to do so. If you are in the European Economic Area (EEA) and believe your rights have not been addressed, you have the right to lodge a complaint with your local data protection authority.

8. Account & Data Deletion

You may request the deletion of your account and all associated data at any time — even without the App installed — by visiting our Support page or emailing contact@wearesomos.com. All data will be permanently deleted from our database within 3–5 business days of your request.

9. Third-Party Content

Videos in the App are played through the YouTube embedded player, and YouTube may collect information during playback in accordance with its own policies. To minimize tracking, we use the youtube-nocookie.com domain. Please refer to the Google Privacy Policy for details.

10. Security

We implement industry-standard measures to protect your personal data. However, no method of transmission over the internet or electronic storage is 100% secure, and we cannot guarantee absolute security.

11. Changes to This Policy

This Privacy Policy takes effect on October 17, 2026, and supersedes the previous policy (effective May 13, 2026). If we add, remove, or modify any of its contents, we will notify you via in-app notice or our website at least 7 days before the changes take effect. Continued use of the App after the effective date constitutes acceptance of the updated policy.
