Privacy Policy
Your privacy is our highest priority at ExcelClash. We believe in radical transparency regarding the information we collect and how we use it to build your experience as a spreadsheet engineer. This policy explains our data practices and your rights regarding your personal information.
1. Information We Collect
We collect several types of information: (1) Account Metadata: including email addresses, hashed passwords, and system usernames. (2) Analytical Telemetry: Performance data such as formula solver attempts, completion times, and battle mode rankings. (3) Technical Logs: IP addresses, browser types, and device identifiers to prevent fraud and ensure technical stability. This data allows us to maintain the integrity of our global leaderboard and refine the difficulty of our modules.
2. How We Use Your Information
Your data is utilized exclusively to provide and improve ExcelClash services. Specifically, we use it to: maintain your persistent session, track your educational progress, verify your battle victories, and communicate important platform updates. We do not engage in automated decision-making that has legal or significant effects on you. We process your data based on your consent and our legitimate interest in providing the service.

ExcelClash will never sell your personal information to third parties. We may share data only with: (1) Trusted infrastructure providers (like our database hosts) who are bound by strict confidentiality agreements. (2) Legal authorities if required by valid subpoena or legal process. (3) Other users, but only in the form of public leaderboard rankings and battle results which do not expose sensitive personal identifiers.
4. Cookies and Local Storage
We use secure cookies and local storage tokens to store essential technical state: solver progress, UI preferences, and authentication tokens. These are required for the platform to function correctly. We do not use third-party tracking pixels or behavioral advertising cookies. You can manage your cookie preferences through your browser settings, though some features may become unavailable.
5. Security Measures
We implement robust technical and organizational measures to protect your data, including end-to-end encryption for sensitive data transfers and regular security audits. However, no method of transmission over the internet is 100% secure, and we cannot guarantee absolute data protection against all possible threats.
