Privacy Policy

1. Who We Are

LineUs is a shared canvas app that lets you draw and connect with one person you pair with (for example, a partner or close friend).

Data controller: DNBT media

Contact: contact@dnbtmedia.hu

2. Information We Collect

2.1 Account information

When you sign in, we collect information from your authentication provider:

• Google Sign-In and/or Apple Sign-In

This may include your email address, display name, profile picture (if available), and a unique user ID.

We do not receive or store your Google or Apple password.

2.2 Onboarding information

When you first use the App, you may answer optional questions about how you plan to use LineUs (for example, relationship type, how often you are apart, age range, gender, how you heard about us, and use case). We store your answers to improve the App.

We also store your app version and device platform (Android or iOS).

2.3 Pairing and subscription information

To connect you with another user and manage premium access, we process:

• Pairing codes you create or enter
• Your linked partner’s user ID
• Subscription status (subscriber or invited partner)
• Partner invite codes and related subscription metadata

Payments are processed by Google Play or the Apple App Store. We do not collect or store credit card or bank details.

2.4 Content you create

When you use LineUs, we store:

• Drawings and canvas data (stroke data) shared with your paired partner
• Saved drawings if you use the Vault feature (stored as image files)

This content is shared only with the user you are paired with. It is not public.

2.5 Device and technical information

• Push notification token (via Firebase Cloud Messaging), if you allow notifications — used to notify you when your partner sends a drawing or similar activity
• Local data on your device (for example, login state, pairing ID, preferences) stored in the App’s local storage

2.6 Subscription management

We use RevenueCat to manage subscriptions and verify premium access. RevenueCat receives information linked to your App user ID and purchase status from Google Play or the App Store.

3. How We Use Your Information

We use your information to:

• Create and manage your account
• Pair you with another user
• Sync and display shared drawings in real time
• Send push notifications (if enabled)
• Process and manage subscriptions and partner invite codes
• Improve the App using onboarding responses
• Maintain security and prevent abuse
• Comply with legal obligations

4. How We Share Your Information

We do not sell your personal information.

We share information only in these cases:

• With your paired partner — drawings and pairing-related data necessary for the App to work
• With service providers who help us operate the App:
  • Supabase — authentication, database, and file storage
  • Google — sign-in and (on Android) billing
  • Apple — sign-in and (on iOS) billing
  • Firebase (Google) — push notifications
  • RevenueCat — subscription management
• When required by law — for example, court order or legal process
• To protect rights and safety — if we believe disclosure is necessary to prevent harm or fraud

Each provider has its own privacy policy governing how they handle data.

5. Data Storage and International Transfers

Your data is stored on servers operated by our providers (including Supabase). These servers may be located outside your country, including in the United States or the European Union.

Where required by law, we rely on appropriate safeguards for international data transfers (such as standard contractual clauses).

6. Data Retention

We keep your information for as long as your account is active or as needed to provide the App.

If you delete your account or request deletion, we will delete or anonymize your personal data within a reasonable time, except where we must retain it for legal, tax, or security reasons.

You can disconnect from a partner at any time in the App. Disconnecting ends the pairing but does not by itself delete your account.

7. Your Rights

Depending on where you live, you may have the right to:

• Access the personal data we hold about you
• Correct inaccurate data
• Request deletion of your data
• Restrict or object to certain processing
• Withdraw consent (for example, by disabling push notifications in your device settings)
• Lodge a complaint with a data protection authority

To exercise these rights, contact us at: contact@dnbtmedia.hu

If you are in the European Economic Area, you may also contact your local supervisory authority (for example, the Hungarian National Authority for Data Protection and Freedom of Information — NAIH).

8. Children’s Privacy

LineUs is not intended for children under 13 (or under 16 in some countries where a higher age applies). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, contact us and we will delete it.

9. Security

We use technical and organizational measures to protect your data, including encrypted connections (HTTPS/TLS) and access controls on our backend. No method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

10. Push Notifications

If you enable notifications, we use your device token to send alerts about activity from your paired partner. You can turn off notifications at any time in your device settings.

11. Subscriptions

• Subscriptions are billed through Google Play or the Apple App Store under their terms.
• One subscription can cover the subscriber and one partner who joins via an invite code without a separate payment.
• Free trial terms, pricing, and cancellation are shown in the App and in the store listing.
• Manage or cancel your subscription through your Google Play or Apple account settings.

12. Third-Party Links

The App may reference third-party services (for example, store billing pages). We are not responsible for their privacy practices.

13. Changes to This Policy

We may update this Privacy Policy from time to time. We will post the updated version with a new “Last updated” date. If changes are significant, we may notify you in the App or by other reasonable means.

Continued use of the App after changes means you accept the updated policy.
