Effective Date: 26 October 2026
Last Updated: 26 October 2026

1. Introduction

Welcome to National Sheet (“we,” “our,” “us,” or the “App”). National Sheet is an educational platform designed to help university students access academic resources, read and organize PDF documents, and use educational tools and AI-powered features.

This Privacy Policy explains how National Sheet collects, uses, stores, protects, and shares personal information when you use our mobile application, website, and related services.

By using National Sheet, you acknowledge that you have read this Privacy Policy.

2. Information We Collect

Depending on the features you use, we may collect the following categories of information.

2.1 Account and Profile Information

When you create or manage an account, we may collect:

Name or display name.
Email address.
Mobile phone number.
University name.
Department or institute.
Academic year, semester, and university session.
Profile picture, if provided.
Account authentication identifiers associated with supported login methods.

If you sign in using Google or another supported authentication provider, we may receive the information authorized through that provider.

2.2 Educational Content and Uploaded Files

When you use the educational features, we may process:

PDF documents and other supported academic materials you upload.
Document titles, descriptions, course names, and related academic information.
Bookmarks, reading progress, highlights, annotations, and personalized document information.
Information necessary to manage document access, permissions, and visibility.

Please do not upload confidential documents or another person’s personal information unless you have the necessary rights and authorization.

2.3 AI Features and User Queries

If you use AI-powered features, we may process the questions, prompts, text, and document content that you submit to provide answers and improve the functionality of the requested service.

AI responses may be generated using the platform’s configured AI infrastructure or third-party AI services, depending on the feature and configuration.

You should avoid including passwords, financial account credentials, or other unnecessary sensitive information in AI prompts.

2.4 Payment Information

If you purchase premium features or subscriptions, we may process transaction identifiers, payment status, subscription details, and information needed to verify payments.

Payments may be handled through supported payment providers, such as bKash, Nagad, Rocket, or other providers made available in the service.

We do not intend to store your complete payment card credentials or mobile financial service PINs. Payment providers may independently collect and process information under their own privacy policies.

2.5 Technical and Usage Information

Depending on the services enabled, we may collect technical information such as:

Device type, operating system, and app version.
IP address and basic connection information.
App diagnostics, crash reports, and error logs.
Authentication sessions and security-related events.
Usage information needed to operate the platform, enforce limits, prevent abuse, and maintain service reliability.

We collect only the technical information reasonably necessary for the relevant purposes and enabled features.

3. How We Use Your Information

We may use information for the following purposes:

To create, authenticate, and manage user accounts.
To personalize the application based on your university, department, academic year, session, and courses.
To provide access to educational PDFs and academic resources.
To support PDF reading, downloading, bookmarking, highlighting, and document organization.
To provide AI-assisted educational features and process submitted questions.
To process payments and manage premium access.
To enforce document permissions, subscription limits, and access controls.
To protect accounts, prevent fraud, and investigate abuse.
To troubleshoot errors, maintain performance, and improve service reliability.
To communicate essential service, security, or account-related notices.
To comply with applicable legal obligations and enforce our terms.

We will not use personal information for purposes materially different from those described here without an appropriate legal basis or notice where required.

4. How We Share Information

We do not sell personal information to third parties in exchange for money.

We may share relevant information in the following circumstances:

4.1 Service Providers

We may use service providers for hosting, storage, authentication, payment processing, security, analytics, customer support, and AI processing. These providers may process information only as necessary to provide their services, subject to applicable agreements and legal requirements.

4.2 Other Users

Some profile or academic information may be visible to other National Sheet users depending on your privacy settings and the platform’s features.

For example, your name, university, department, academic year, or uploaded educational materials may be visible according to the relevant feature’s permissions.

Your email address and mobile number should be displayed according to the applicable privacy settings. However, no online service can guarantee that information voluntarily shared with another person will remain confidential.

4.3 Payments and Transactions

Relevant transaction information may be shared with payment providers to verify transactions, process payments, prevent fraud, and manage subscriptions.

4.4 Legal and Safety Requirements

We may disclose information where reasonably necessary to comply with applicable law, respond to lawful requests, protect users, investigate security incidents, or enforce our rights.

4.5 Business Transfers

If the service is involved in a merger, restructuring, or transfer of ownership, relevant information may be transferred subject to applicable privacy requirements.

5. PDF Documents and Access Permissions

National Sheet may provide public, department-specific, course-specific, or personal document libraries.

The visibility of a document depends on its settings, permissions, and the applicable access rules. You are responsible for choosing appropriate visibility settings when uploading content.

We may apply access controls and document protection measures, including personalized watermarks on downloaded documents where supported.

We cannot guarantee that every document will remain inaccessible to unauthorized persons if a user downloads, copies, photographs, or otherwise redistributes it.

You must upload only materials you own or are legally authorized to share. We may restrict or remove content that violates applicable law, intellectual property rights, or our terms.

6. AI Services

AI features are intended to support educational activities. AI-generated answers may contain errors, omissions, or outdated information and should not be treated as guaranteed accurate.

When you submit a question or document to an AI feature, the relevant content may be processed by the AI infrastructure configured for that feature.

If a third-party AI provider is used, the submitted content may be transmitted to that provider to generate a response. Its processing practices may also be governed by its own policies and contractual terms.

We will not claim that AI content is processed exclusively on our own servers unless that is actually the case for the specific feature.

7. Data Storage and Retention

We retain personal information for as long as reasonably necessary to provide the service, maintain your account, fulfill legitimate operational purposes, resolve disputes, enforce agreements, and comply with applicable legal obligations.

Uploaded PDFs and associated information may remain stored while they are needed for the relevant library, account, or platform feature.

Retention periods may differ depending on the type of information and the reason it is collected. Some information may remain in backups or transaction records for a limited period after deletion, where necessary for security, recovery, or legal compliance.

When information is no longer needed, we will take reasonable steps to delete it or anonymize it, subject to applicable requirements.

8. Data Security

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

Depending on the service, these measures may include secure connections, access controls, authentication protections, and restricted access to stored information.

No internet transmission or electronic storage system is completely secure. We therefore cannot guarantee absolute security.

You are responsible for keeping your login credentials confidential and notifying us if you suspect unauthorized access to your account.

9. Your Privacy Choices and Rights

Depending on applicable law, you may have the right to:

Access or review certain personal information.
Correct inaccurate account or profile information.
Change available privacy and document visibility settings.
Request deletion of your account and associated personal information.
Withdraw consent where processing relies on consent.
Request information about relevant data processing practices.

You can update information through the app’s profile or privacy settings where those options are available.

To request access, correction, or deletion, contact us using the contact details provided at the end of this policy.

We may need to verify your identity before fulfilling a request. Some information may need to be retained where required by law or for legitimate security and transaction purposes.

10. Account and Data Deletion

You may request deletion of your National Sheet account and associated personal information by using an available account-deletion option or contacting our support team.

Account deletion request page: [Insert your publicly accessible account-deletion URL, if available]

If the app allows users to create accounts, we will provide an appropriate way to request account deletion from within the app and, where required by Google Play, through an external web resource.

When a valid deletion request is processed, we will delete or anonymize associated information that we are not required or otherwise permitted to retain.

Some records, such as legally required transaction records, fraud-prevention records, or limited backups, may be retained for the applicable period.

Deleting the app from your device does not necessarily delete your account or data.

11. Children’s Privacy

National Sheet is an educational service intended for university students and other users who are legally permitted to use the service.

The service is not specifically directed at children under 13. We do not knowingly collect personal information from children under 13 in violation of applicable law.

If you believe that a child has provided personal information inappropriately, please contact us so that we can investigate and take appropriate action.

Where applicable law requires parental consent or imposes additional protections for minors, we will comply with those requirements.

12. Third-Party Services and Links

The application may use or link to third-party services, including authentication providers, payment services, hosting providers, analytics tools, advertising services, or AI services.

Those services may have their own privacy policies and terms. We encourage you to review their policies before using them.

National Sheet is not responsible for the independent privacy practices of third-party services outside our control.

13. International Data Processing

Depending on the hosting infrastructure and service providers used, information may be processed or stored in Bangladesh or other countries.

Where personal information is transferred internationally, we will take steps required by applicable law to protect that information.

14. Changes to This Privacy Policy

We may update this Privacy Policy when our features, technologies, service providers, or legal obligations change.

The updated policy will be published on our designated Privacy Policy webpage, with the revised effective or updated date.

Where required by law, we will provide additional notice or obtain consent for material changes.
