Watermark KTP is a free Android app developed by Refourma that provides a secure way to protect your personal data during transactions that require KTP (Indonesian ID card) verification. With this app, you can add a watermark to your KTP image to verify its authenticity. The watermark includes the purpose, date, and name, which can be customized to meet your needs.

The app offers two different watermark styles that you can choose from to position the watermark on your KTP. The best part is that the app works offline, ensuring that your data remains safe and secure. Watermark KTP doesn't send any of your data to the developer or any third-party, making it a trustworthy solution for securing your KTP data.
