Protacta Privacy Policy

November 4, 2026

Protacta’s lessons run on your device. The app has no required account, advertising, third-party analytics or cross-app tracking. The Classic Dart App Clip plays one fold on your device without camera, microphone or purchase access.

Camera and surroundings

If you choose AR or supported paper guidance, Protacta asks for camera access. Camera images, available depth information and room geometry are processed on your device to place a guide or compare a supported paper state. Normal lessons do not save camera photos to storage or send them to a developer server. A step check may temporarily show the frame it used so you can compare your paper with the guide.

Optional voice control and read-aloud

When you turn on voice control and grant microphone and speech recognition access, Protacta temporarily processes audio and recognized English commands using Apple’s on-device recognition where available. Protacta does not fall back to server recognition, keep recordings or transcripts, or upload the audio or recognized words. Stop voice control from the lesson or leave the app. Read-aloud speaks written instructions with Apple’s speech synthesis and does not need microphone access.

Progress and diagnostics

Protacta saves lesson progress, completion state and playback preferences on your device. A small local troubleshooting file may include the app version, lesson, step and AR tracking status. These records are not automatically uploaded and do not include camera images, room coordinates or purchase credentials.

Purchases

Apple processes purchases, subscriptions and restores. Protacta checks verified Apple transactions to determine access. We do not receive your payment-card details through the app. Apple handles purchase records under Apple’s Privacy Policy.

Support messages

When you choose to email support, we receive your address and the information or attachments you send. We use them to answer your request and troubleshoot the issue. We keep correspondence as needed to handle the request and maintain necessary support records. You can request access, correction or deletion by emailing adrianchenyuqiu@gmail.com. The email services you and we use process the message.

Your choices

You can withdraw camera, microphone or speech recognition permissions in your device settings and keep using the 3D guide. Deleting the app removes local files from the device. Apple manages device backups and App Store records under your Apple settings and services.
