Public Terms of Service

1. Description of the Service

DSA CheatSheet provides an interactive Data Structures & Algorithms revision workbench featuring curated problem sheets, 4-Box Invariant study materials, client-side code scratchpads, spaced-repetition tracking, optional cloud synchronization and real-time document collaboration, and an optional AI Copilot.

2. Accounts & Authentication

You may use local-only features without an account. Cloud sync, collaborative editing, and the AI Copilot require signing in with a supported social identity provider (Google or Apple). You are responsible for maintaining the security of your third-party login credentials and for activity performed under your account.

3. User Content & Collaboration

• Ownership: You retain ownership of the personal notes, custom sheets, and code snippets you create in DSA CheatSheet.
• License to Operate: When you use cloud sync or collaboration, you grant us a limited license to store, synchronize, and transmit your content solely as needed to operate the service for you and your invited collaborators.
• Shared Documents: When you create an invite link, anyone with that valid invite can access the shared document with the role you assign (viewer or editor). You are responsible for sharing invite links responsibly and revoking access when no longer needed.

4. AI Copilot & Quotas

AI Copilot usage is subject to daily per-user and global service quotas, which we may adjust to preserve service stability. AI outputs are provided solely as study aids and may contain inaccuracies or bugs—you are responsible for independently verifying any code, complexity claims, or algorithmic reasoning.

5. Acceptable Use

You agree not to:

• Attempt to bypass authentication, authorization, rate limits, daily AI quotas, or security controls.
• Use automated bots or excessive traffic to scrape, disrupt, or overload the API, WebSocket sync service, or CDN.
• Store or distribute unlawful, infringing, abusive, or malicious content through shared documents or invites.

6. Intellectual Property

Except for your user-created content and third-party open-source packages, the DSA CheatSheet interface, curated problem sheets, invariants, complexity proofs, and reference solutions are protected by applicable intellectual property laws.

7. Disclaimers & Limitation of Liability

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT. WE DO NOT GUARANTEE UNINTERRUPTED AVAILABILITY, ERROR-FREE CONTENT, OR INTERVIEW OUTCOMES. LOCAL-ONLY DATA STORED IN YOUR BROWSER'S INDEXEDDB MAY BE LOST IF YOU CLEAR BROWSER DATA WITHOUT CLOUD SYNC.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, DSA CHEATSHEET AND ITS OPERATORS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF DATA OR PROFITS, ARISING FROM YOUR USE OF THE SERVICE.

8. Changes & Contact

We may update these Terms from time to time by updating the “Last updated” date above. Continued use of the service after changes take effect constitutes acceptance of the updated Terms. Questions about these Terms can be sent to support@dsacheatsheet.com.
