Terms of Use
Last updated: 25 October 2026
1. Learning materials
Published lectures, notes and writings on Arko & English are shared for personal study. You may download and print them for your own learning or classroom use with credit. Do not republish or sell them without permission. Availability may change when the creator updates or withdraws a material.
2. Optional accounts
Reading published materials does not require an account. Saving, liking, commenting and using the study assistant require sign-in. Keep your account secure and use Settings to manage your profile, password and other sessions.
3. Study assistant
The assistant is a learning aid, not a substitute for your teacher. Responses can be incorrect. Check important answers against your textbook or teacher, and do not submit confidential information. Usage is limited to five questions per rolling 24 hours for readers and fifty for the creator.
4. Respectful participation
Keep comments relevant and respectful. Do not post abusive content, spam or someone else's private information. The creator may remove inappropriate comments.
5. Previews and external services
Previews depend on file format and service availability; use the download option when a preview is unavailable. External sites and sign-in services have their own terms.
6. Questions and permissions
For corrections, reuse permission or questions about these terms, email mrahmanwrites@gmail.com.
