1. WHAT INFORMATION DO WE COLLECT?

Personal information you disclose to us

In Short: We collect the limited personal information you voluntarily provide to us, plus certain information collected automatically when you use the App.

We collect personal information that you voluntarily provide to us when you express an interest in obtaining information about us or our products and Services, when you participate in activities on the Services, or otherwise when you contact us. The App does not require you to create an account or log in.

Sensitive Information. We do not process sensitive information.

Application Data. If you use the App, we may also collect the following information:

  • Mobile Device Permissions. If the App requests access to specific device features (such as camera or storage) for a particular function, that access is used only for that function, and you can review or change these permissions at any time in your device settings.
  • Mobile Device Data. We automatically collect device information (such as device model and manufacturer), operating system and version, system configuration information, device and application identifiers, and Internet Protocol (IP) address. This information is primarily needed to maintain the security and operation of the App, for troubleshooting, and for internal analytics and reporting.
  • Analytics Data. We use Firebase / Google Analytics for Firebase (provided by Google LLC) to understand how the App is used, including app interactions, session and diagnostic data, and device and app identifiers. Because the App is used by children, we configure these analytics tools in a child-appropriate manner (for example, disabling personalised/interest-based advertising identifiers) consistent with the Google Play Families Policy and applicable children’s privacy laws.
  • Purchase and Subscription Data. If you make an in-app purchase or subscribe within the App, the transaction itself is handled by the Apple App Store or Google Play. Subscription and entitlement status is managed on our behalf by RevenueCat, our subscription-management provider. We do not receive or store your payment card details; RevenueCat and the app stores process purchase history, subscription status, and related anonymised identifiers on our behalf.

All personal information that you provide to us must be true, complete, and accurate, and you must notify us of any changes to such personal information.

2. HOW DO WE PROCESS YOUR INFORMATION?

In Short: We process your information to provide, improve, and administer the App, to operate in-app purchases and subscriptions, for analytics and diagnostics, for security and fraud prevention, and to comply with law.

We process your personal information for a variety of reasons, depending on how you interact with our Services, including:

  • To deliver and maintain the App’s core features and functionality.
  • To operate in-app purchases and subscriptions through our payment and subscription-management providers.
  • To understand, in aggregate, how the App is used, so that we can maintain and improve it.
  • To save or protect an individual’s vital interest, such as to prevent harm.

3. WHAT LEGAL BASES DO WE RELY ON TO PROCESS YOUR INFORMATION?

In Short: We only process your personal information when we have a valid legal reason to do so, such as consent (including, where applicable, parental consent), to comply with law, to fulfil a contract, or for our legitimate interests.

If you are located in the EU or UK, this section applies to you. The General Data Protection Regulation (GDPR) and UK GDPR require us to explain the valid legal bases we rely on:

  • Consent. We may process your information where you (or, where applicable, your parent or legal guardian) have given us permission to use your information for a specific purpose. Consent can be withdrawn at any time.
  • Contract. We may process your information where necessary to provide the Services you have requested, including operating in-app purchases and subscriptions.
  • Legal Obligations. We may process your information where necessary for compliance with our legal obligations.
  • Vital Interests. We may process your information where necessary to protect your vital interests or those of a third party.

If you are located in Canada, this section applies to you. We may process your information if you have given us express or implied permission to use it for a specific purpose, and you can withdraw that consent at any time, subject to the limited exceptions recognised under Canadian law (for example, for fraud detection and prevention, or where required by a court order).

4. WHEN AND WITH WHOM DO WE SHARE YOUR PERSONAL INFORMATION?

In Short: We may share information with the service providers listed below, and in the specific business situations described in this section.

We share personal information with the following categories of service providers, each of which processes personal information only as necessary to provide their services to us:

  • Google LLC (Firebase / Google Analytics for Firebase) — app analytics and diagnostics.
  • RevenueCat, Inc. — subscription and in-app purchase management.
  • Apple Inc. and Google LLC (via the App Store and Google Play) — app distribution and payment processing.

We may also need to share your personal information in the following situation:

  • Business Transfers. We may share or transfer your information in connection with, or during negotiations of, any merger, sale of company assets, financing, or acquisition of all or a portion of our business to another company.

5. HOW LONG DO WE KEEP YOUR INFORMATION?

In Short: We keep your information for as long as necessary to fulfil the purposes outlined in this privacy notice, unless otherwise required by law.

We will only keep your personal information for as long as it is necessary for the purposes set out in this privacy notice, unless a longer retention period is required or permitted by law (such as tax, accounting, or other legal requirements). When we have no ongoing legitimate business need to process your personal information, we will either delete or anonymise it, or, if this is not possible, securely store it and isolate it from further processing until deletion is possible.

6. HOW DO WE KEEP YOUR INFORMATION SAFE?

In Short: We aim to protect your personal information through a system of organisational and technical security measures.

We have implemented appropriate and reasonable technical and organisational security measures designed to protect the security of any personal information we process. However, despite our safeguards, no electronic transmission over the Internet or information storage technology can be guaranteed to be 100% secure, so we cannot promise or guarantee that unauthorised third parties will never be able to defeat our security. Transmission of personal information to and from the Services is at your own risk; you should only access the Services within a secure environment.

7. WHAT ARE YOUR PRIVACY RIGHTS?

In Short: In some regions, such as the EEA, UK, and Canada, you have rights that allow you greater access to and control over your personal information.

In some regions, you have certain rights under applicable data protection laws. These may include the right to (i) request access to and obtain a copy of your personal information, (ii) request rectification or erasure, (iii) restrict the processing of your personal information, and (iv) where applicable, data portability. You may also have the right to object to certain processing. If you are a parent or legal guardian of a child who uses the App, you may exercise these rights on your child’s behalf by contacting us using the details in Section 13.

We will consider and act upon any request in accordance with applicable data protection laws. If you are located in the EEA or UK and believe we are unlawfully processing your personal information, you have the right to complain to your Member State or UK data protection authority. If you are in Switzerland, you may contact the Federal Data Protection and Information Commissioner.

Withdrawing your consent: Where we rely on consent to process your personal information, you have the right to withdraw it at any time by contacting us at alfredoeffenberg@gmail.com. This will not affect the lawfulness of processing carried out before the withdrawal.

8. DO WE COLLECT INFORMATION FROM CHILDREN?

In Short: Yes, the App may be used by children, and we take additional steps to protect children’s privacy in accordance with applicable law, including COPPA and GDPR.

  • The App is designed to be suitable for, and may be used by, children under the age of 13, and in some regions under the age of 16.
  • We do not knowingly collect more personal information from children than is reasonably necessary to provide the App’s core functionality.
  • We do not use children’s information for behavioural or interest-based advertising, and we do not knowingly sell or share children’s personal information.
  • Where required by applicable law (such as the U.S. Children’s Online Privacy Protection Act (COPPA), or the GDPR as implemented in the EU, UK, or Germany), we seek appropriate consent from a parent or legal guardian before collecting personal information from a child, where such collection occurs.
  • If you are a parent or guardian and believe your child has provided us with personal information without appropriate consent, or you wish to review, correct, or request deletion of your child’s information, please contact us at alfredoeffenberg@gmail.com. We will respond to such requests as required by applicable law.

9. CONTROLS FOR DO-NOT-TRACK FEATURES

Most web browsers and some mobile operating systems and applications include a Do-Not-Track („DNT“) feature or setting you can activate to signal your preference not to have data about your online browsing activities monitored and collected. No uniform technology standard for recognising and implementing DNT signals has been finalised. As such, we do not currently respond to DNT browser signals or any other mechanism that automatically communicates your choice not to be tracked online. If a standard for online tracking is adopted that we must follow in the future, we will inform you in a revised version of this privacy notice.

10. DO CALIFORNIA RESIDENTS HAVE SPECIFIC PRIVACY RIGHTS?

In Short: Yes, if you are a resident of California, you are granted specific rights regarding access to your personal information.

California Civil Code Section 1798.83 (the „Shine The Light“ law) permits California residents to request, once a year and free of charge, information about categories of personal information (if any) we disclosed to third parties for direct marketing purposes in the preceding calendar year. If you are a California resident and would like to make such a request, please submit it in writing using the contact information in Section 13.

If you are under 18, reside in California, and have posted content on the Services, you have the right to request removal of that content by contacting us with the email address associated with your account and a statement that you reside in California. We will make sure the data is not publicly displayed, though it may not be completely removed from all our systems (e.g., backups).

CCPA Privacy Notice

The California Code of Regulations defines a „resident“ as (1) every individual who is in California for other than a temporary or transitory purpose, and (2) every individual domiciled in California who is outside the state for a temporary or transitory purpose. All other individuals are „non-residents.“

What categories of personal information do we collect? We have not collected any of the CCPA-enumerated categories of personal information (identifiers, California Customer Records data, protected classifications, commercial information, biometric information, internet/network activity, geolocation, audio/visual data, professional information, education information, or inferences) in the preceding twelve (12) months, beyond the limited device, analytics, and purchase/subscription information described in Section 1.

You may contact us by email at alfredoeffenberg@gmail.com, or by referring to the contact details in Section 13. If you use an authorised agent to exercise your rights, we may deny the request if the agent does not submit proof of valid authorisation.

Will your information be shared with anyone else? Scientific Learning Lab Hannover has not disclosed, sold, or shared any personal information to third parties for a business or commercial purpose in the preceding twelve (12) months, and will not sell or share personal information belonging to website visitors, users, or other consumers in the future. In accordance with the CCPA’s protections for minors, we do not sell or share the personal information of consumers we know to be under 16 years of age without opt-in consent and, for consumers under 13, without verifiable parental consent.

Your rights with respect to your personal data include the right to request deletion of your data, the right to be informed about our collection and use practices, the right to non-discrimination for exercising your privacy rights, and the right to limit use and disclosure of sensitive personal information (which, as noted above, we do not process).

Upon receiving a request, we will need to verify your identity before acting on it, using information you have previously provided to us or by contacting you through a previously provided communication method. We will only use the information you provide for verification for that purpose, and will delete any additional verification information as soon as verification is complete.

To exercise these rights, contact us by email at alfredoeffenberg@gmail.com, or by referring to the contact details in Section 13. If you have a complaint about how we handle your data, we would like to hear from you.

11. DO VIRGINIA RESIDENTS HAVE SPECIFIC PRIVACY RIGHTS?

In Short: Yes, if you are a resident of Virginia, you may be granted specific rights regarding access to and use of your personal information.

Under the Virginia Consumer Data Protection Act (CDPA), a „consumer“ is a natural person who is a Virginia resident acting only in an individual or household context (not a commercial or employment context). „Personal data“ is information linked or reasonably linkable to an identified or identifiable individual, excluding de-identified data or publicly available information. „Sale of personal data“ means the exchange of personal data for monetary consideration.

Scientific Learning Lab Hannover has not sold any personal data to third parties for business or commercial purposes, and will not do so in the future.

Your rights with respect to your personal data may include the right to be informed whether we are processing it, to access it, to correct inaccuracies, to request deletion, to obtain a copy of data you previously shared with us, and to opt out of processing used for targeted advertising, sale, or certain profiling.

You may exercise these rights by contacting us at alfredoeffenberg@gmail.com or via the contact details in Section 13. If you use an authorised agent, we may deny the request if the agent does not submit proof of valid authorisation.

Upon receiving your request, we will respond without undue delay, and in all cases within forty-five (45) days of receipt, with one possible forty-five (45) day extension where reasonably necessary (of which we will notify you within the initial period, together with the reason).

Right to appeal: If we decline to act on your request, we will inform you of our decision and reasoning. You may appeal by emailing alfredoeffenberg@gmail.com; within sixty (60) days of receipt of an appeal, we will inform you in writing of any action taken, including a written explanation of the reasons for our decision. If your appeal is denied, you may contact the Virginia Attorney General to submit a complaint.
