Our principal infrastructure providers include:

Third-party providers may process information in countries other than your country of residence, subject to their arrangements and applicable law.

3.2 Public Study Sets

If you designate a study set as public, its contents and associated public-facing information may be available to other users and search engines.

Depending on the features available, this may include your display name, username, profile picture, study set title, description, flashcards, and other information you choose to make public.

Do not publish information you want to keep confidential.

Where required, we will apply appropriate safeguards and provide notice or seek consent.

3.5 With Your Consent

We may share information for other purposes where you direct us to do so or provide the consent required by applicable law.

4. Advertising and Analytics

QuizKuma may display advertisements to support free access to the Services.

If we use third-party advertising providers, they may collect or receive information such as browser identifiers, device information, IP addresses, cookie identifiers, and information about interactions with advertisements, subject to applicable law and your consent where required.

These providers may use such information to deliver, measure, personalize, or limit advertising.

We may also use analytics tools to understand traffic, identify technical problems, measure engagement, and improve the platform.

Advertising and analytics providers may have their own privacy policies governing their processing of information. We encourage you to review those policies.

Where required by law, we will provide appropriate cookie controls and obtain consent before enabling non-essential advertising or analytics technologies.

If QuizKuma offers a paid advertising-free subscription, the scope of advertising removal will be explained in the relevant subscription terms. Removing advertisements does not necessarily disable essential cookies, security processing, or all analytics unless expressly stated.

5. Payment Information

If paid subscriptions or other purchases are offered, payments may be processed by third-party payment providers.

Payment providers may collect information such as your name, billing details, payment method, transaction amount, and transaction identifiers as necessary to complete the transaction and prevent fraud.

QuizKuma may receive limited payment-related information, such as transaction status, subscription status, billing dates, and payment provider identifiers.

We do not intend to store complete payment card numbers or card security codes on QuizKuma's own application database.

Payment processing is subject to the applicable payment provider's terms and privacy policy.

6. Data Retention

We retain personal information for as long as reasonably necessary to provide the Services, fulfil the purposes described in this Privacy Policy, comply with legal obligations, resolve disputes, enforce agreements, and protect our systems.

Retention periods vary according to the type of information and the reason it is collected.

For example:

• Account information is generally retained while your account remains active.
• Study sets and flashcards are retained until you delete them or your account is deleted, subject to legitimate retention needs.
• Learning history is retained while needed to provide progress features and related services.
• Support correspondence may be retained for an appropriate period to resolve requests and maintain records.
• Security and technical logs may be retained for limited periods appropriate to security, diagnostics, and legal requirements.
• Payment and transaction records may be retained as required by applicable financial, tax, and legal obligations.

When information is no longer required, we will take reasonable steps to delete it, anonymize it, or securely dispose of it, subject to applicable law and technical limitations.

Deleted information may remain temporarily in backup systems before being removed through normal backup cycles.

Marketing Communications

If we send promotional emails, you may unsubscribe through the link provided in the email or contact us directly. We may continue to send essential service messages, such as account security notices and important service updates.

8. Account and Content Deletion

You may request deletion of your QuizKuma account by using available account controls or contacting info@quizkuma.com.

When an account deletion request is verified and processed, we will take reasonable steps to delete or anonymize personal information associated with the account, subject to legal obligations, security needs, legitimate dispute resolution, and other lawful retention grounds.

Deleting your account may make your study sets, flashcards, practice history, and profile information unavailable to you.

Public content may already have been copied, shared, cached, or indexed by third parties. We cannot guarantee removal of copies held by independent third parties or search engines, although we may take reasonable steps within our control where appropriate.

If you wish to remove a particular study set without deleting your account, use the available content management controls or contact us for assistance.

9. International Data Transfers

QuizKuma and its service providers may process or store information in countries outside your country of residence, including countries where data protection laws may differ from those in your jurisdiction.

When personal information is transferred across borders, we will take steps appropriate to the circumstances and required by applicable law to protect the information.

Depending on the circumstances, safeguards may include contractual protections, appropriate security measures, and other legally recognized transfer mechanisms.

Where required by law, we will provide additional information about international transfers and the applicable safeguards.

10. Security

We use reasonable technical and organizational measures designed to protect personal information against unauthorized access, loss, misuse, alteration, or disclosure.

Depending on the service and information involved, these measures may include access controls, authentication, encryption provided by our infrastructure or service providers, monitoring, backups, and security updates.

No website, database, transmission method, or storage system can be guaranteed to be completely secure.

You are responsible for maintaining the confidentiality of your login credentials, using appropriate account security practices, and notifying us if you suspect unauthorized access to your account.

If a personal information breach occurs, we will take appropriate steps to investigate, mitigate harm, and provide notifications where required by applicable law.

11. Children's Privacy

QuizKuma is a general learning platform and is not intended to collect personal information from children in circumstances where such collection is prohibited or requires consent that has not been obtained.

Age requirements and parental consent obligations may vary by jurisdiction. Where required, children may use relevant Services only with appropriate parental or legal guardian consent and supervision.

Parents or legal guardians who believe that a child has provided personal information in violation of applicable requirements may contact info@quizkuma.com.

We will assess the request and take appropriate action, which may include deleting information or restricting the relevant account, subject to applicable law.

We do not knowingly collect children's personal information for purposes prohibited by applicable law.

12. Third-Party Links and Services

QuizKuma may contain links to third-party websites, educational resources, media, or services.

We do not control the privacy practices, security, or content of independent third parties. Accessing those services is subject to their own terms and privacy policies.

We encourage you to review third-party privacy policies before providing them with personal information.

13. Automated Processing and Future Features

QuizKuma may introduce features that use automated processing to generate questions, recommend study materials, analyze learning activity, or personalize the learning experience.

If such features are introduced, the information processed will depend on the functionality involved. We will provide additional information or obtain consent where required by applicable law.

You should avoid submitting sensitive personal information into learning tools unless the feature specifically requires it and you understand how the information will be handled.

We will not represent automated recommendations, generated questions, or learning assessments as guaranteed to be accurate or suitable for every purpose.

We may update this Privacy Policy to reflect changes in the Services, our data practices, service providers, legal requirements, or security measures.

The updated policy will be published on QuizKuma.com with a revised effective date.
