Accounts
Sign-in uses your Google account. Keep your account secure and use information you are authorized to provide. If you need a parent or guardian’s permission to use Shrjan, obtain it first. Your learning account is personal; avoid sharing sign-in access.
Practice and scores
Shrjan provides original practice questions and explanations. Practice score ranges are approximate learning feedback and are not official SAT scores, validated score predictions, or a guarantee of exam results. Use official College Board and Bluebook resources for official practice and exam information. Shrjan is not affiliated with or endorsed by College Board.
Beta service
Shrjan is free during its beta. Features and practice material may change, and interruptions or mistakes may occur. Report errors through the contact email. Any future paid features will be disclosed before purchase; using the beta does not authorize a charge.
Responsible use
Do not attempt to access another account’s data, disrupt the service, exploit security weaknesses, distribute abusive content, or use the service to cheat on a live examination. We may restrict access when necessary to protect users or the service.
External services and content
Google, Desmos, and College Board have their own terms. Linking to a service does not grant rights to reproduce its content. Use Shrjan’s practice material for your own learning; do not redistribute it as your own commercial question bank without permission.
Privacy and deletion
Our privacy notice explains account data, learning records, analytics, and deletion requests. You can reset learning progress in Settings or request account deletion by email.
