Terms of use
Policy version: 2026-09-27-r2
Use Paper Common for lawful learning and revision. You must have permission to distribute every document you upload. Do not submit confidential examination material, personal information, malicious files, or material that infringes another person’s rights.
Your right to upload
Upload only material you created and have the right to license, or material for which you have permission covering this platform's use. That permission must cover every question, answer, image and extract, including material belonging to schools, teachers, publishers or examination bodies. Keep evidence of permission and provide it if requested. If you are unsure, do not upload.
Possessing, buying, receiving or finding a paper online does not by itself give you permission to share it here. Removing names, adding answers, crediting the author, or using it for education does not by itself authorize redistribution. A school's classroom licence may not cover an independent sharing platform.
Do not upload unreleased or confidential examinations, restricted teacher resources, or copied textbooks, commercial question banks, HKEAA papers or marking schemes without authorization covering this service. School papers containing third-party questions also require the necessary rights. Remove student names, marks and other personal details. Preserve copyright notices and required attribution, and ensure your permission covers any changes needed to prepare files for publication.
Permission you grant the platform
You retain any copyright you hold. By submitting files, you grant Paper Common a non-exclusive, worldwide, royalty-free licence, limited to operating this service, to store, copy, scan, process file formats, make changes needed to prepare reviewed versions for publication, including redaction or omission of pages, generate and display public previews, and make reviewed files available to members for download and lawful personal study. Our service providers may perform these tasks on our behalf. You must have authority to grant these rights for all included material; uploading cannot grant rights you do not hold.
You may ask us to stop sharing your submission through Contact. After removal, we stop offering new access through the service. We may retain restricted copies and records only as needed for backups, security, legal obligations or dispute handling. Removal cannot recall copies already downloaded or end uses that remain lawful independently of this licence.
Download credits
New accounts start with zero credits. One approved complete submission earns 4 credits. An approved partial set with its answers earns 2 credits. One credit unlocks one approved set. Repeat downloads of that set are free while the set and your account are available. Credits have no cash value and cannot be sold or transferred.
Moderation and availability
Publication approval, file safety checks and download credits do not certify copyright ownership or permission. Credits provide access within this service; they do not buy copyright or authorize further distribution. We may request permission evidence, withhold publication, or remove access when rights are uncertain.
We may request corrections, reject duplicates, suspend accounts, and remove papers. Approval can be reversed with an audited credit adjustment. If awarded credits have already been spent, recovery remains pending rather than making your balance negative. Content may contain errors; verify answers independently.
Responsible access
Use downloaded resources only for lawful personal learning within the permissions that apply to them. Do not resell, repost or distribute files without the necessary permission. Do not bypass access controls or remove copyright notices. Nothing in these terms removes rights or exceptions that applicable law gives you.
Do not evade access controls, scrape private files, share account credentials, or redistribute downloaded material without permission. Contact support to dispute moderation or credit decisions.
Copyright violations and account access
We suspend service access for users who repeatedly infringe copyright, taking account of the evidence and any successful challenges. A serious violation may also result in immediate suspension. Do not upload removed material again, alter it to avoid review, or use another account to bypass a restriction. Relevant contribution credits may be reversed under our moderation rules.
