Assessment results are informational and are not treated by NeuroBoost as a clinical diagnosis or professional medical evaluation.

• Related usage records, processing status, usage dates, safety flags, error records, and moderation records where applicable.

3.How We Use Information

We use information to:

4.Legal Bases for Processing

Where applicable privacy laws require a legal basis, we process personal data based on one or more of the following grounds:

• Performance of a contract when processing is necessary to provide the app, account, subscription, games, training, assessments, progress, and support features you request.

• Consent, or explicit consent where required, for optional communications, optional data uses, or information treated as sensitive under applicable law.

• Legitimate interests in operating, securing, troubleshooting, analyzing, and improving the Service, provided those interests are not overridden by your rights and interests.

• Compliance with legal obligations and the establishment, exercise, or defense of legal claims where applicable.

Where processing is based on consent, you may withdraw that consent at any time. Withdrawal does not affect the lawfulness of processing carried out before the withdrawal.

5.How We Share Information

We do not sell personal information in the ordinary meaning of that term. We may share information with the following categories of recipients only as reasonably necessary for the purposes described in this Privacy Policy:

• Cloud hosting and data-processing providers that store or process information needed to operate the Service.

• Authentication providers that help users create accounts, sign in, verify identity, and manage account security.

• Analytics, diagnostics, and crash-reporting providers that help us understand app usage, reliability, and user experience.

• Artificial intelligence or automated-processing providers that support explanations, reports, recommendations, app functionality, safety review, or customer support, subject to contractual safeguards where applicable.

• Content and technology providers that support brain games, training activities, assessment logic, scores, and reports.

• Communication and support providers that help us send service messages, deliver notifications, and respond to user requests.

• Apple, Google, or similar platform providers when you use their authentication, app distribution, subscription, analytics, notification, or device services.

• Professional advisors, authorities, courts, regulators, or transaction counterparties when reasonably necessary for legal compliance, safety, corporate transactions, or the protection and enforcement of rights.

Service providers are permitted to process information only for the services they provide to us and as otherwise allowed by their contracts and applicable law.

6.Artificial Intelligence and Automated Features

Some explanations, training insights, recommendations, reports, or other outputs may be generated automatically by algorithms or, where disclosed, assisted by artificial intelligence. These features are intended to support brain training, education, entertainment, and general wellness. They do not provide medical, psychological, psychiatric, or other professional healthcare advice.

Automated or AI-assisted outputs may contain inaccuracies, omissions, or bias. Do not rely on them for diagnosis, treatment, medication decisions, emergency assistance, or other significant healthcare decisions.

We recommend that you do not submit passwords, payment-account credentials, highly sensitive health information, or confidential third-party information through AI-powered, automated, or support features unless the relevant feature expressly requests that information and explains how it will be handled.

7.International Transfers

Your information may be processed in countries or regions other than where you live. Where required by applicable law, we use appropriate safeguards for international transfers, such as contractual safeguards, vendor due diligence, adequacy mechanisms, or other lawful transfer methods.

8.Data Retention

We retain personal information only for as long as reasonably necessary to provide the Service, maintain your account, preserve training and game history, calculate progress features, comply with legal obligations, resolve disputes, enforce agreements, prevent fraud or abuse, and support security or safety reviews.

Training records, scores, Brain Power values, streaks, assessment summaries, and related history may be retained while your account remains active because they form part of your saved progress. Retention periods may vary depending on the type of information, the feature used, legal requirements, and operational needs.

When you delete your account, we will delete or de-identify associated account data within a reasonable period, except for information that we must or are permitted to retain for legal compliance, security, fraud prevention, dispute resolution, or enforcement purposes. Backup copies may remain for a limited period before being securely overwritten or deleted.

9.Your Choices and Rights

• Account access and updates: You may update certain account information in the app, including your display name, email address, and password where supported.

• Notifications: You may change reminder settings in the app or through your device's notification settings.

• Account deletion: You may request account deletion through the Service where supported. Deleting an account permanently removes associated cloud data and cannot be undone, except for information we must or are permitted to retain under applicable law.

• Consent: Where processing is based on consent, you may withdraw consent at any time.

• Privacy rights: Depending on your location, you may have rights to access, correct, delete, restrict, or object to processing; opt out of certain processing; receive a portable copy of your information; or request information about the categories of personal data processed and the categories of recipients to whom data has been disclosed.

• Complaints: Where applicable, you may have the right to complain to a data protection or privacy authority in your country or region.

To exercise a privacy right, contact contact@iqbrainboom.com. We may need to verify your identity before completing a request. We will respond within the period required by applicable law.

10.Security

We use reasonable technical and organizational measures designed to protect personal information against unauthorized access, loss, misuse, alteration, or disclosure. No method of transmission or storage is completely secure. You are responsible for maintaining the confidentiality of your login credentials and for using a strong, unique password.

11.Children and Age Limits

NeuroBoost is a general-audience brain training service and is not directed to children under 13. We do not knowingly collect personal information from children under 13 without the consent or authorization required by applicable law.

Users who are below the age of legal capacity in their location may use the Service only with the involvement and consent of a parent or legal guardian where permitted. If we learn that we collected personal information from a child in violation of applicable law, we will take reasonable steps to delete it. If you believe a child has provided personal information without the required authorization, contact us at contact@iqbrainboom.com.

12.Third-Party Links and Services

The Service may link to or interact with third-party platforms, authentication providers, payment services, app stores, or educational and cognitive references. Their privacy practices are governed by their own privacy policies and terms, not this Privacy Policy.

13.Changes to This Privacy Policy

We may update this Privacy Policy from time to time. If changes are material, we will provide notice as required by applicable law, such as through the app, by email, or by updating the effective date. Where required, we will obtain your consent before applying a material change to information already collected.
