Privacy Policy

Last updated: August 12, 2026

SmileStory Inc. ("we", "us", or "our") operates WIA Code (https://wiacode.com). This Privacy Policy explains how we collect, use, and protect your information when you use our service.

1. Information We Collect

WIA Code is designed with privacy in mind. We collect minimal information:

• Language Preference: Stored locally in your browser (localStorage) to remember your language setting.
• Camera Access: Used only for real-time WIA Code scanning. Camera data is processed entirely on your device and is never transmitted to our servers. Only if on-device decoding fails and you explicitly tap the optional “Cloud Decode” button, that single image is sent to our server for decoding and is not stored.

2. Data We Do NOT Collect

• We do not collect personal identification information unless you voluntarily provide it.
• We do not store any data from scanned WIA Codes on our servers.
• We do not sell, trade, or share your data with third parties.

3. WIA Code Data Processing

All WIA Code encoding and decoding happens locally in your browser by default. The data stored inside a WIA Code is processed on your device only. Scanned content is sent to our servers only when you explicitly opt in to the Cloud Decode fallback, and it is not stored.

4. Cookies and Local Storage

We use localStorage to save your language preference and PWA settings. We do not use cookies.

5. PWA and Offline Usage

When you install WIA Code as a PWA (Progressive Web App), the application files are cached on your device via Service Worker. This enables offline scanning. No personal data is cached — only application code.

6. Children's Privacy

WIA Code is designed for all ages. We do not knowingly collect personal information from children under 13. If you believe a child has provided us personal information, please contact us.

7. Data Security

We implement industry-standard security measures. Since WIA Code processes data locally on your device, the risk of data breach is minimized by design.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date.
