Privacy Policy

Effective Date: April 14, 2024

1. Introduction

Welcome to Dual N-Back! This Privacy Policy explains how Dual N-Back, LLC ("we," "us," or "our") collects, uses, shares, and protects information in relation to our web application, website (dualnback.com), and associated services (collectively, the "Service").

Your privacy is important to us. Please read this Privacy Policy carefully. By accessing or using our Service, you agree to the collection, use, disclosure, and procedures this Privacy Policy describes. If you do not agree to this policy, please do not use the Service. This Privacy Policy is incorporated into and subject to our Terms of Use.

2. Information We Collect

We collect information to provide, operate, improve, understand, customize, support, and market our Service. The types of information we collect depend on how you use our Service:

A. Information You Provide Directly:

  • Account Information: When you create an account, we collect your email address and a hashed version of your password. If you sign up using Google Sign-In, we receive information from Google such as your email address and potentially your name and profile picture, as permitted by your Google account settings.
  • Profile Information: We collect the unique username you choose for each profile, along with your training progress data including your current N-Back level, current difficulty (N.00-N.95), highest achieved N-Back level, and consecutive success streak. You may manage multiple profiles under one account.
  • Journal Content: We collect the text, tags, and any linked session or chart data you voluntarily add to your personal journal entries within the Service ("User Content").
  • Friend Information: If you use the friend features, we collect information about your friend connections and pending requests (usernames and profile IDs).
  • Settings: We store your profile-specific settings, such as customized key bindings and preferences like instant feedback enablement.
  • Communications: If you contact us directly (e.g., via support@dualnback.com), we may receive additional information about you such as your name, email address, the contents of the message and/or attachments you may send us, and any other information you may choose to provide.

B. Information Collected Automatically:

  • Session & Performance Data: When you use the training features, we automatically collect detailed data about your sessions, including timestamps, duration, N-back level played, difficulty level played, modality (dual, visual, audio), specific stimuli presented (visual positions, audio letters), your responses (match/no-match, timing), accuracy, hits, misses, false alarms, and calculated metrics like d-prime sensitivity.
  • Replay Data: For standard sessions, we collect a log of events including stimulus presentations, user responses, and feedback timing to enable the session replay feature.
  • Usage Data & Analytics: We may automatically collect information about how you interact with the Service using tools like Firebase Analytics (if enabled). This may include features used, session durations, general usage patterns, device type, browser type, IP address (which may infer general location), operating system, and crash reports. This data is primarily used in aggregated or anonymized form.

3. How We Use Information

We use the information we collect for various purposes, including:

  • To Provide and Operate the Service: To authenticate users, manage accounts and profiles, deliver the core dual n-back training, calculate performance, store progress, provide analytics, enable journaling, facilitate friend interactions and leaderboards, and allow session replays and sharing.
  • To Improve and Personalize the Service: To understand user behavior and trends, analyze performance data (including aggregated/anonymized journal content analysis as described in Section 5 of the Terms of Use) to improve the training algorithms and user experience, develop new features, conduct research related to cognitive training, and personalize settings.
  • To Communicate With You: To respond to your support requests or inquiries, send important service-related notices (e.g., updates to Terms or Privacy Policy), and potentially provide information about beta programs or new features (with options to opt-out where applicable).
  • For Security and Fraud Prevention: To monitor for suspicious activity, prevent abuse, enforce our Terms of Use, and protect the security and integrity of the Service and our users.
  • To Comply with Law: To comply with applicable legal obligations, respond to valid legal requests, or protect our rights or the rights of others.

4. How We Share Information

We do not sell your personal information. We may share information under the following limited circumstances:

  • Service Providers: We share information with third-party service providers that help us operate, provide, improve, understand, customize, support, and market our Service. Currently, this primarily includes Google Cloud Firebase (for authentication, database hosting, cloud functions, hosting, and potentially analytics). These providers are bound by contractual obligations to keep personal information confidential and use it only for the purposes for which we disclose it to them.
  • User-Controlled Sharing:
    • Friends: If you use the friend features, your username and certain performance data (as displayed on leaderboards, e.g., average level, time played) will be visible to users you have added as friends.
    • Journal Entries & Replays: If you choose to share a journal entry or a session replay publicly or with specific friends, the content you designate for sharing (which may include journal text, performance data, and your username) will be accessible to those recipients according to the sharing mechanism you use. You are responsible for managing your sharing settings and the content you share.
  • Aggregated or Anonymized Data: We may share aggregated or anonymized information (data that does not personally identify you) for research, statistical analysis, industry reporting, or other legitimate business purposes.
  • Legal Requirements: We may disclose your information if required to do so by law or in the good faith belief that such action is necessary to comply with a legal obligation, protect and defend our rights or property, prevent or investigate possible wrongdoing in connection with the Service, protect the personal safety of users of the Service or the public, or protect against legal liability.
  • Business Transfers: If Dual N-Back, LLC is involved in a merger, acquisition, financing due diligence, reorganization, bankruptcy, receivership, sale of company assets, or transition of service to another provider, your information may be sold or transferred as part of such a transaction as permitted by law and/or contract.

5. Data Retention

We retain your personal information for as long as your account is active or as needed to provide you the Service.

Upon account termination or deletion request (initiated via your account settings or by contacting us at support@dualnback.com), we will take steps to delete or anonymize your personally identifiable information within a reasonable timeframe (e.g., 30-90 days, subject to system limitations and backup cycles). This includes your account credentials, profile details, session history linked directly to you, and journal entries.

We may retain certain data for longer periods if required by law, for necessary security purposes (e.g., fraud prevention), to resolve disputes, enforce our agreements, or for our legitimate business needs, such as maintaining aggregated/anonymized analytical data derived from your usage. Anonymized data is information that can no longer be used to identify you.

6. Data Security

We implement reasonable technical and organizational measures designed to protect your information from unauthorized access, use, alteration, or disclosure. We utilize Firebase's security features, including secure connections (HTTPS), Firestore security rules, and password hashing. However, please be aware that no security measures are perfect or impenetrable, and we cannot guarantee the absolute security of your information. You are responsible for maintaining the security of your account password.

7. Your Rights and Choices

Depending on your location and applicable law, you may have certain rights regarding your personal information. These may include the right to:

  • Access: Request access to the personal information we hold about you.
  • Correction: Request correction of inaccurate personal information.
  • Deletion: Request deletion of your personal information, subject to legal and operational retention needs (see Section 5 and Section 9 of the Terms of Use).
  • Manage Settings: Update your profile settings (e.g., key bindings, feedback preferences) within the Service.
  • Manage Sharing: Manage sharing settings for journal entries and replays where applicable features are provided.

You can typically exercise these rights through your account settings page or by contacting us at support@dualnback.com. We will respond to your requests in accordance with applicable laws.

8. Children's Privacy

Our Service is not directed to individuals under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that we have collected personal information from a child under 13 without verification of parental consent, we will take steps to remove that information from our servers. If you believe that we might have any information from or about a child under 13, please contact us at support@dualnback.com.

9. International Data Transfers

Your information may be transferred to, and maintained on, computers located outside of your state, province, country, or other governmental jurisdiction where the data protection laws may differ from those in your jurisdiction. If you are located outside the United States and choose to provide information to us, please note that we transfer the data, including personal information, to the United States (where Firebase servers are primarily located) and process it there. Your consent to this Privacy Policy followed by your submission of such information represents your agreement to that transfer.

10. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any significant changes by posting the new Privacy Policy on this page (https://dualnback.com/privacy) and updating the "Effective Date" at the top. We may also provide notice through the Service or via email if you have provided one. You are advised to review this Privacy Policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page. Your continued use of the Service after the effective date constitutes your acceptance of the revised policy.
