Tiếng Việt (tóm tắt): Ứng dụng lưu rất ít dữ liệu: một mã tài khoản, email nếu bạn tạo tài khoản, lịch sử mua hàng, các sự kiện sử dụng và các báo lỗi bạn gửi. Câu trả lời và tiến độ học chỉ nằm trên điện thoại của bạn. Chúng tôi không bán dữ liệu và không có quảng cáo. Xóa tài khoản: Tài khoản → Xóa tài khoản. Bản tiếng Anh bên dưới là bản chính thức.
Español (resumen): La app guarda lo mínimo: un identificador de cuenta, tu correo si creas una cuenta, el historial de compras, eventos de uso y los reportes que envíes. Tus respuestas y tu progreso se quedan en tu teléfono. No vendemos datos y no hay anuncios. Para eliminar tu cuenta: Cuenta → Eliminar cuenta. La versión en inglés de abajo es la oficial.
Nail Tech Exam Prep: Texas (shown as “Nail Tech Exam” on your phone) is a study app for the Texas Manicurist (nail technician) written exam. The short version: we store the minimum needed to keep your purchase working and to improve the questions, your answers and progress stay on your device, there is no AI and no advertising in the app, we do not sell your data, and payment details never reach us.
Data is stored in Google Firebase (Cloud Firestore) in the United States.
Your answers, session and practice-test results, missed-question lists, progress, and your language settings are stored on your device only. Deleting the app deletes them.
The question audio is recorded in advance and ships inside the app. The app never uses your microphone and sends nothing when you play audio.
The full version is a one-time purchase through the Apple App Store or Google Play, managed with RevenueCat. We receive a purchase record (product, date, store transaction and your account id) so we can unlock the app and restore it on a new device. We never see your payment card details.
The app is meant for adults and students preparing for a professional license exam. We do not knowingly collect data from children under 13.
This app is an independent study aid. It is not affiliated with, sponsored or endorsed by the Texas Department of Licensing and Regulation (TDLR) or PSI. Practice questions are original and do not reproduce actual exam content.
If you created an account, you can delete it from Account → Delete account. This deletes your account record and your sign-in immediately, and clears the app’s data on your device. Backups roll off within 30 days. Usage events and problem reports carry only your account id; after deletion nothing links that id to you, and we delete them on request. Guests can sign out to discard the guest identity, or email us to remove its data. You can email support@confidencelabs.app at any time to request access, correction or deletion.
If we make material changes, we will update this page and the date above.
