Privacy Policy
Last updated: 2026 april 23
LaSu is built to help you master new languages by providing AI-powered translations for the text you encounter while browsing. We believe your data is yours, and we keep our privacy practices simple and transparent.
1. Data We Process
LaSu only processes the **specific text you highlight or select** on web pages. We do not collect or monitor your browsing history, personal identifiers, financial information, or precise location data.
2. How AI Processing Works
To provide high-quality translations, your selected text is sent securely to our servers and then to third-party AI providers (such as OpenAI).
- Anonymity: We do not send your name or account details to AI providers.
- Purpose: Data sent to these providers is used solely to generate the translation or explanation you requested.
- History: Translations are saved to your personal history so you can review and practice them later.
3. Local Storage & Preferences
Settings such as your target language, UI preferences, and feature toggles are stored locally on your device (using LocalStorage or cookies) to ensure a seamless experience across browsing sessions.
4. Security & Data Sharing
We use industry-standard HTTPS encryption for all data in transit. LaSu does not sell your data to advertisers. We only share selected text with our AI sub-processors to fulfill the core service of the app.
5. Your Rights
You have full control over your learning data. You can clear your translation history or reset your settings at any time within the app interface.
