Privacy Keyboard

🔐 Privacy Keyboard

This project was developed in just one weekend (2 days). The main goals were: first, to create a button that corrects text, as I communicate in several different languages; and second, to improve privacy. I built it because I noticed that when I typed something when use other keyboard and then browsed websites or watched videos, I would sometimes see ads related to what I had written.

Privacy Keyboard is a simple, secure keyboard designed with privacy as the top priority. It lets you type freely while keeping your data on your device. No tracking, no data collection, and no unnecessary permissions.

Simply press the AI button to fix grammar, spelling, and clarity issues instantly — very important when communicating in multiple languages. Text is shared with Gemini AI only when you press the AI button. Otherwise, your messages are not accessed or transmitted to Gemini at any time.

✏️ Optional Text Correction

This feature is completely optional and only works when you activate it.
