Terms of Use
Last updated: 31 October 2026. These terms cover Project Cherenkov, a student-run educational project. They are not legal advice and should be reviewed by a qualified lawyer before launch. An Indonesian version is at /id/terms.
1. Scope
Project Cherenkov is an educational website and archive of olympiad editorials, interactive visualizations, study materials and planner tools. Using it means you accept these terms; if you do not, please do not use the account features.
2. Accounts
You are responsible for your account and password. Give accurate information. If you are under 18, use an account only with the permission of a parent or guardian. We may suspend accounts that abuse the service.
3. Acceptable use
Use the content for lawful, educational purposes. Do not abuse, break, overload or interfere with the site, scrape it in a way that harms it, or submit harmful, abusive or infringing content.
4. Content and licences
The source code is released under the licence in the LICENSE file. Unless a page says otherwise, the editorials, explanations and visualizations are © their authors, who are named on each page. You may read, share links to, and quote short excerpts with attribution; ask us before republishing or reusing more.
<!-- OWNER DECISION: pick a content licence (for example CC BY-SA 4.0 or all rights reserved) and replace the sentence above. Past exam problems quoted or adapted from OSN or other competitions remain the property of their organisers. -->5. AI features
The Neutrino chat uses a third-party AI model, so its answers can be wrong. Check anything important against the editorials and your teachers. Do not rely on it for exam decisions. See the Privacy Policy for how chat data is handled.
6. Accuracy
We aim to be correct, but content is for learning and may contain errors or be revised. Please report mistakes.
7. No warranty and limits on liability
The project is provided "as is" without warranties, including availability and fitness for a particular purpose. To the extent the law allows, we are not liable for indirect or consequential loss arising from using the site. Nothing here limits rights you have under Indonesian consumer or data-protection law that cannot be limited.
8. Governing law
These terms are governed by the laws of Indonesia.
9. Changes
We may update these terms and will show the date above. For material changes we will notify signed-in users in advance instead of treating continued use as acceptance.
