Privacy Policy

At Deck Nexus, we are committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use the Deck Nexus app and related services.

This Privacy Policy applies to the Deck Nexus application for mobile devices, created by Daniil Bystrov (the "Service Provider") as a freemium service.

1. Information We Collect

We may collect the following categories of information:

• Personal Information: name, email address, and other contact information you choose to provide.
• Account Information: account ID, sign-in provider, and authentication-related data for email, Apple, Google, or anonymous access.
• Collection Information: cards you save, wishlist items, binder organization, portfolio snapshots, tags, and related collector activity.
• Scanner Information: camera access, captured card images, scan results, collector numbers, OCR output, and scan correction actions.
• Transaction Information: subscription status, entitlement data, purchase restoration state, and App Store billing metadata processed through Apple and RevenueCat.
• Device and Usage Data: device model, iOS version, app version, crash reports, diagnostics, app interactions, push notification tokens, analytics identifiers, and certain attribution or infrastructure data such as IP address processed by service providers.
• Support and Feedback Information: messages you send to us, optional email address, device model, iOS version, app version, and whether you want a reply.

2. How We Collect Information

We collect information through:

• Account registration, login, linking, and authentication flows.
• In-app usage, including scanning cards, searching the database, updating wishlists, and managing your collection.
• Support and feedback forms or direct email communications.
• Analytics, diagnostics, attribution, and crash-reporting SDKs integrated into the app.
• Third-party services used for infrastructure, purchases, authentication, notifications, and analytics.

3. Why We Collect Your Information

We use your information to:

• Create and manage user accounts.
• Authenticate and authorize logins across supported sign-in methods.
• Sync and maintain your collection, wishlist, and portfolio data.
• Enable card scanning, card recognition, card database search, and related collector workflows.
• Process subscriptions, restore purchases, and manage premium access.
• Send service-related notifications and maintain app functionality.
• Analyze app usage, improve reliability, detect abuse, and troubleshoot issues.
• Respond to support requests and feedback submissions.
• Comply with legal, security, and regulatory obligations.

4. Email Communications

Deck Nexus may send transactional and service-related emails as part of providing the service, particularly when you use email-based authentication or contact support.

These emails may include:

• Account-related messages such as sign-in confirmations, verification requests, password-reset or security notices.
• Important service updates related to your account or subscription.
• Customer support responses.

Our authentication or email service providers may also process limited delivery metadata needed to send and secure these communications.

5. Cookies, Tracking, and Similar Technologies

The Deck Nexus mobile application itself does not rely on traditional browser cookies in the same way a website does. However, the app and related web pages may use similar technologies and SDKs such as local storage, device identifiers, attribution tools, analytics identifiers, and push notification tokens for:

• Essential functionality such as sign-in, session management, and app configuration.
• Performance monitoring, crash reporting, and diagnostics.
• Analytics and usage measurement.
• Attribution and install-source measurement, including Apple Search Ads attribution where applicable.
• Push notification delivery and device messaging.

Where required by platform rules or law, we request permission before using certain tracking-related capabilities such as App Tracking Transparency.

6. Sharing Your Information

We do not sell your personal information. We may share information with service providers such as:

• Authentication and Infrastructure Providers such as Supabase.
• Analytics and Diagnostics Providers such as Firebase Analytics, Firebase Crashlytics, and Amplitude.
• Notification Providers such as Firebase Messaging.
• Payment and Subscription Providers such as Apple and RevenueCat.
• Authentication Providers such as Apple Sign In and Google Sign-In.
• Card image, pricing, search, or market-data providers used to power card recognition and collection features.

These third parties process data on our behalf or as independent service providers subject to their own terms and privacy policies. We may also disclose information when required by law, to protect users, or to enforce our rights.

7. Data Retention

We retain data only for as long as necessary to provide the services described above, maintain security, resolve disputes, comply with legal obligations, and enforce agreements. After that, data is deleted, de-identified, or anonymized as appropriate.

8. Your Rights

Depending on your location, including the EU, UK, California, and other regulated regions, you may have rights to:

• Access your personal data.
• Request correction of inaccurate information.
• Request deletion of your data.
• Object to or restrict certain processing.
• Request portability of applicable personal data.
• Withdraw consent where processing is based on consent.

To exercise these rights, contact us at daniil.bystrov@gmail.com.

9. Data Deletion

You may request deletion of your Deck Nexus account and associated personal data. Deck Nexus also includes account deletion functionality in the app settings for supported account types.

When an account is deleted:

• Associated account data is removed or scheduled for removal from our active systems.
• Certain records may be retained where required by law, fraud prevention, billing reconciliation, or legitimate security purposes.

10. International Data Transfers

Deck Nexus operates using service providers that may process information in countries outside your home jurisdiction, including the United States and other locations where our providers maintain infrastructure.

Where required, we take reasonable steps to ensure personal data remains protected in accordance with applicable privacy laws.

11. Children's Privacy

Deck Nexus is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that a child has provided personal data, we will take steps to delete that information promptly.

12. Data Security

We implement appropriate technical and organizational measures to protect personal data, including:

• Secure authentication and access control.
• Encryption in transit where supported by our providers.
• Crash monitoring, diagnostics, and operational safeguards.
• Reasonable controls around infrastructure and service-provider access.

However, no system can guarantee absolute security.

13. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. When significant changes are made, we may notify users through in-app messaging, service communications, or updates on our website. The latest version will always be available on this page.
