This Privacy Policy describes how the At-Mark mobile application (the “Application” or “At-Mark”) handles information in connection with your use of it. At-Mark is developed and provided by Arpan Patra (the “Developer”, “we”, “us”, or “our”). Please read this Policy carefully. By downloading, installing, or using the Application, you acknowledge that you have read and understood this Policy and agree to the practices and terms described in it. If you do not agree with this Policy, please do not use the Application.

1. Definitions

• “Application” means the At-Mark software application and all of its features, in any version or format.
• “Device” means the smartphone, tablet, or other device on which the Application is installed.
• “Personal Data” means any information relating to an identified or identifiable individual.
• “User Content” means any information you create, enter, import, or store using the Application, including class names, student names, roll numbers, and attendance records.
• “You” or “User” means the individual who installs or uses the Application.

2. Scope of This Policy

This Policy applies solely to the Application. It does not apply to any third-party websites, platforms, services, or applications that you may access from or use alongside the Application, each of which is governed by its own privacy practices. We are not responsible for the content or privacy practices of any third party.

3. Information We Do Not Collect

The Application does not require you to create an account, sign in, or provide any contact information in order to use it. We do not collect, receive, store on our systems, or have access to:

• your name, email address, telephone number, or other contact details;
• your precise or approximate location;
• device identifiers, advertising identifiers, or persistent tracking identifiers;
• analytics, usage, or behavioural data about how you interact with the Application; or
• any User Content you enter into the Application.

The Application contains no advertising and no advertising or analytics software development kits that transmit your information to us or to advertisers.

4. User Content and Your Responsibilities

The Application allows you to record information such as class names, student names, roll numbers, and attendance. This User Content is stored locally on your Device and is never transmitted to or made accessible to the Developer. Because the User Content remains entirely under your control on your Device, you are solely responsible for it, including its accuracy, its lawful collection and use, and its security.

You represent and warrant that, in respect of any Personal Data relating to other individuals (such as students, who may be minors) that you choose to record using the Application, you have all rights, authorizations, consents, and lawful bases necessary to collect, store, and process that information, including, where required by applicable law, the consent of the individuals concerned or of their parents or legal guardians. You are responsible for complying with all laws, regulations, and institutional policies applicable to your collection and use of such information. The Developer acts only as the provider of a local software tool and is not a controller, processor, or custodian of your User Content.

5. How Your Information Is Stored and Processed

All User Content is stored in a private database within the Application’s storage area on your Device. This storage area is sandboxed by the operating system and is not designed to be accessible to other applications. All processing necessary to provide the Application’s features — such as calculating attendance percentages or generating reports — takes place locally on your Device. We do not maintain any copy of your User Content.

6. Device Permissions

The Application requests only the permissions necessary for it to function, which may include:

• Internet access — used to check for and download updates to the Application and to enable you to share files that you choose to share. This does not transmit your User Content to us.
• Vibration — used to provide haptic feedback in response to your actions.
• File access on your request — invoked only when you actively choose to import a roster file or to share an exported report, using your Device’s built-in file picker and sharing tools. The Application does not browse, scan, or upload your files on its own.

The Application does not request access to your location, camera, microphone, contacts, or photo library.

7. Network Communications and Service Providers

The Application is built and distributed using established third-party platforms that support its delivery and maintenance:

• Expo provides build and over-the-air update infrastructure. When the Application checks for or downloads an update, it communicates with Expo’s servers to retrieve application code and assets. These communications do not include your User Content or Personal Data about you. See Expo’s privacy policy at https://expo.dev/privacy.
• Google Play distributes the Application and manages installations and updates. Google may process limited technical information in connection with that distribution under its own policies. See https://policies.google.com/privacy.

These providers operate independently and process information under their own privacy policies. We do not control, and are not responsible for, their practices.

8. Children’s Privacy

The Application is intended for use by educators and other adults for the purpose of recording attendance. It is not directed to, marketed to, or intended for use by children, and children are not the users of the Application. We do not knowingly collect Personal Data from any person, including children, because we do not collect User Content at all. Any information about students that an adult user chooses to record is stored solely on that user’s Device, remains under that user’s control, and is governed by Section 4 of this Policy.

9. Data Retention and Deletion

Because we do not store your User Content, we do not retain it and have nothing to delete on our side. You control the retention of your information directly:

• you may delete individual records (such as a student, a class, or a day’s attendance) within the Application; and
• you may uninstall the Application, which removes the User Content stored by the Application from your Device.

You are responsible for maintaining your own backups of any information you wish to preserve. Uninstalling the Application or losing access to your Device may result in permanent loss of locally stored User Content.

10. Security

We have designed the Application so that your User Content remains on your Device, which reduces the risks associated with transmitting and storing data on remote servers. However, no method of electronic storage is completely secure, and we cannot guarantee absolute security. You are responsible for protecting your Device through appropriate measures such as a screen lock, device encryption, and keeping your operating system up to date.

11. Your Rights and Choices

Depending on your jurisdiction, you may have rights regarding Personal Data relating to you, such as the rights to access, correct, or delete it. Because the Developer does not collect or hold any Personal Data about you, these rights are exercised by you directly through your control of the information stored on your Device, as described in Section 9. If you believe we hold information about you, you may contact us using the details in Section 19.

12. International Users

The Application is operated from India and may be used in other countries. Because the Application processes information locally on your Device, your User Content is not transferred across borders by us. You are responsible for ensuring that your use of the Application complies with the laws applicable in your location.

13. Future Features and Changes to This Policy

We may update, improve, or expand the Application over time. If we introduce a feature in the future that involves the collection, transmission, or processing of information in a manner that differs from this Policy — for example, an optional cloud backup, account, synchronization, analytics, or diagnostic feature — we will update this Policy to describe that feature before or at the time it becomes available, and, where required by applicable law, we will request your consent before such a feature is activated. Any such feature that involves additional data practices will be made optional or will be clearly disclosed to you.

We may also revise this Policy from time to time for legal, regulatory, or operational reasons. When we do, we will change the “Last updated” date above and, where appropriate, make the revised Policy available within the Application or through the channel where it is published. Your continued use of the Application after a revision takes effect constitutes your acceptance of the updated Policy. We encourage you to review this Policy periodically.

14. Disclaimer of Warranties

To the maximum extent permitted by applicable law, the Application is provided on an “as is” and “as available” basis, without warranties or conditions of any kind, whether express, implied, or statutory, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the Application will be uninterrupted, timely, secure, or error-free, that defects will be corrected, or that the Application is free of harmful components. We do not warrant that any records, calculations, or reports produced by the Application are accurate, complete, or fit for any particular purpose, and you are responsible for independently verifying any information, attendance record, or report before relying on it.

15. Limitation of Liability

To the maximum extent permitted by applicable law, in no event shall the Developer be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of data, profits, revenue, goodwill, or business, arising out of or in connection with your access to, use of, or inability to use the Application, whether based on warranty, contract, tort (including negligence), statute, or any other legal theory, and whether or not the Developer has been advised of the possibility of such damages.

Without limiting the foregoing, because all User Content is stored locally on your Device, the Developer shall not be liable for any loss, corruption, deletion, or unauthorized access to such information resulting from device loss, theft, or damage; hardware, software, or operating-system failure; deletion or uninstallation of the Application; your own acts or omissions; or any cause beyond the Developer’s reasonable control. To the maximum extent permitted by applicable law, the Developer’s total aggregate liability for all claims relating to the Application shall not exceed the greater of the amount you paid, if any, for the Application or one United States dollar (USD 1.00). Some jurisdictions do not allow certain limitations of liability, so some of the above limitations may not apply to you; in such cases, the Developer’s liability is limited to the smallest extent permitted by law.

16. Indemnification

You agree to indemnify, defend, and hold harmless the Developer from and against any and all claims, demands, actions, liabilities, damages, losses, costs, and expenses (including reasonable legal fees) arising out of or relating to: (a) any User Content you create, enter, import, store, export, or share using the Application, including any Personal Data of third parties such as students; (b) your failure to obtain any consents, authorizations, or lawful bases required to collect, record, or process such information; (c) your violation of this Policy or of any applicable law, regulation, or institutional policy; or (d) your misuse of the Application.

17. Third-Party Services and Links

The Application may rely on, or allow you to interact with, third-party services and tools, including those used to import or share files. Your use of such third-party services is governed by their respective terms and privacy policies. We do not endorse and are not responsible for the practices, content, or availability of any third-party service. Any product or company names mentioned are the property of their respective owners.

18. Governing Law and Severability

This Policy and any matter relating to the Application shall be governed by and construed in accordance with the laws of India, without regard to its conflict-of-law principles, and subject to any mandatory consumer-protection rights available to you in your place of residence. If any provision of this Policy is held to be invalid or unenforceable, that provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.
