Why can't I send more than 5 messages to a new match?** To ensure a safe and respectful environment for everyone, Natify has a built-in anti-harassment system. If the other person hasn't replied to your messages, you are limited to sending a maximum of 5 consecutive messages. Once they reply, you can chat freely! **2. How does the offline AI translation work?** Natify utilizes an advanced on-device LLM (Large Language Model) that runs entirely offline on your phone. This means your translation requests are processed locally, ensuring ultra-fast results, zero network dependency, and 100% privacy protection. **3. How do I report an inappropriate user?** Trust and safety are our top priorities. You can report or block a user directly from their profile page or within the chat screen. Our moderation team will review the report and take appropriate action. **4. How do I delete my account and data?** You can permanently delete your account and all associated data by going to **Settings → Account → Delete Account** within the app. --- ## 🔒 Privacy Policy **Effective Date:** August 21, 2026 **Last Updated:** August 21, 2026 Natify ("we," "our," or "us") is committed to protecting your privacy.
