WordBlock processes data only to provide vocabulary lookup features triggered by user actions.

• Local browser storage: lookup cache, history, favorites, and AI settings.
• Network requests: selected word content sent to dictionary/etymology services when lookup runs.
• If AI is enabled by user: word and related context may be sent to user-configured AI provider.

2. Purpose of Use

• Provide definition, etymology, morpheme analysis, AI explanation, history, and favorites.
• Improve lookup continuity through local caching and local learning records.
• Not used for advertising personalization.

3. Data Sharing

• We do not sell personal data.
• When AI is enabled, requests are sent to the provider configured by the user.
• Third-party provider handling follows that provider's own policy.

4. Retention & Control

• Data is stored locally in Chrome storage by default.
• Users can disable AI any time.
• Users can remove data by clearing extension storage or uninstalling the extension.
