Privacy Policy

We process only the minimum information necessary to provide study tracking and collaborative tools:

• Anonymous Local Progress (Default): You can use LeetMap Pro completely anonymously without creating an account. When signed out, your solved problem IDs, pinned companies, and active visual theme are saved strictly on your own device via localStorage. This data never touches our servers.
• Authentication Information (Optional): If you choose to sign in to synchronize your progress across multiple devices, authentication is powered securely by Clerk. We store your Clerk user identifier, username, display name, and avatar image. We never store, process, or have access to your passwords or sensitive authentication credentials.
• Cloud Sync Progress: For signed-in users, solved problem slugs, timestamps, and pinned company lists are securely synchronized to our encrypted database to support multi-device continuation and streak tracking.
• Transient Infrastructure Logs: When accessing our site, standard edge request metadata (such as IP address, browser user-agent, and requested route) is processed transiently by Vercel for routing, DDoS defense, and rate-limiting.

LeetMap Pro utilizes strictly necessary, privacy-preserving storage mechanisms:

• Strictly Necessary Session Cookies: Managed by Clerk solely to keep you signed in securely across browser tabs.
• Local Storage: Browser-side key-value pairs used to remember your theme preference (Dark/Light mode) and offline solved status.
• No Advertising or Behavioral Trackers: We do NOT employ third-party advertising cookies, cross-site trackers, Facebook Pixels, or invasive behavioral fingerprinting scripts.

We partner with industry-leading infrastructure providers that maintain strict SOC 2, ISO 27001, and GDPR compliance:

• Vercel Inc.: Global Edge Network hosting, compute execution, and DDoS mitigation.
• Clerk Inc.: SOC 2 Type II certified user identity, encrypted authentication, and session security.

Depending on your jurisdiction (including the European Economic Area, the United Kingdom, and California), you possess statutory privacy rights:

• Right to Access & Portability: You may request a copy of the personal data associated with your account.
• Right to Erasure (“Right to be Forgotten”): You have the absolute right to have all your data deleted from our systems.
• Do Not Sell or Share My Information: Under the California Consumer Privacy Act (CCPA/CPRA), we confirm that we do not “sell” or “share” your personal information for cross-context behavioral advertising.

You maintain total autonomy over your data:

• Anonymous Local Data: Clear your browser's site data or local storage for www.leetmap-pro.com to immediately remove all stored data.
• Cloud Account & Progress: Click on your profile avatar in the header, select “Manage Account”, and choose “Delete Account”. This triggers immediate, permanent erasure of your user profile, solved history, and streak records across all databases.

LeetMap Pro is designed for software engineers, university students, and adult job seekers. We do not knowingly collect or solicit personal information from children under 13 years of age (or under 16 in certain jurisdictions). If we discover that personal data of a minor has been collected without parental consent, we will take immediate steps to delete the information.
