Privacy Policy

Last updated: February 2026

Overview

Vocab Feed is designed with privacy in mind. We collect as little data as possible and never sell or share personal information.

What we store

• Favorites & progress — saved in your browser's local storage. Never sent to our servers.
• Feed settings (language, CEFR level) — saved locally in SharedPreferences.

What we do NOT collect

• No accounts or personal information
• No cookies for tracking
• No advertising or third-party trackers

Third-party services

The app connects to an AI service (via a Cloudflare Worker proxy) to generate vocabulary cards. Only the requested language and difficulty level are sent — no personal data.

Text-to-speech audio may be generated via Google Cloud TTS through the same proxy. No user data is sent beyond the word to be spoken.

Analytics

We use privacy-friendly, anonymous analytics (Aptabase) to understand aggregate usage patterns. No personally identifiable information is collected.
