Privacy Policy — DSA Learning Coach

Last updated: 2026-04-24

DSA Learning Coach (“the Extension”) is a Chrome browser extension that helps users practice Data Structures & Algorithms by generating questions and explanations through an AI provider of the user’s choice (OpenAI or Anthropic).

This policy explains what data the Extension handles, where it is stored, and who it is shared with.

1. Data the Extension handles

The Extension processes the following data, all entered or triggered by the user:

• API keys for the AI provider the user has chosen (OpenAI and/or Anthropic).
• Practice preferences: preferred category, difficulty, code language, and daily goal.
• Practice history: IDs of questions the user has seen, bookmarked questions, streak counters, and the most recently viewed question and explanation.
• Prompt content sent to the AI provider when the user requests a new question or an explanation. This content is generated by the Extension and does not include personal information beyond the user’s category and difficulty selections.

The Extension does not collect, transmit, or store:

• Personally identifiable information (name, email, address, phone, etc.).
• Browsing history outside of the Extension itself.
• Content from other websites or tabs.
• Analytics, telemetry, or crash reports.

2. Where data is stored

• API keys are stored in chrome.storage.sync, which Chrome encrypts and scopes to the signed-in Google account. Keys never leave the user’s browser except when they are attached to a request sent directly to the provider the user selected (OpenAI or Anthropic).
• Preferences and practice history are stored in chrome.storage.local on the user’s device.
• The developer of the Extension does not operate any server and does not receive, log, or have access to any of this data.

3. Data shared with third parties

When the user clicks “New Question” or “Show Intuition”, the Extension sends a request directly from the user’s browser to the AI provider the user has selected:

• OpenAI — https://api.openai.com — when GPT is the active provider. See https://openai.com/policies/privacy-policy
• Anthropic — https://api.anthropic.com — when Claude is the active provider. See https://www.anthropic.com/legal/privacy

The request contains the user’s API key (in the authorization header) and the prompt text. The AI provider’s own privacy policy and terms of service govern what the provider does with that request. The Extension has no visibility into or control over that handling.

Only the active provider’s API key is ever included in a request. The inactive provider’s key is never transmitted.

4. Permissions the Extension requests

• storage — to save settings, API keys, and practice history locally.
• Host permissions for api.openai.com and api.anthropic.com — to send requests to the AI provider the user has selected. No other hosts are accessed.

The Extension does not request activeTab, tabs, webRequest, or any permission that would let it read or modify other web pages.

5. Data retention and deletion

All data is stored on the user’s own device or inside the user’s Google account (for chrome.storage.sync). The user can delete all Extension data at any time by:

1. Removing the Extension from chrome://extensions, or
2. Clearing the Extension’s site data from Chrome settings.

No data is held by the developer, so there is nothing to request deletion of.

6. Children’s privacy

The Extension is not directed to children under 13 and does not knowingly collect data from them.

7. Changes to this policy

If this policy changes, the updated version will be published at the URL where this policy is hosted. The “Last updated” date at the top will reflect the change.

8. Contact

For questions about this policy, open an issue on the project’s public repository or contact the developer at the email listed on the Chrome Web Store listing page.
