Privacy Policy

Last updated: March 29, 2026

O Preco Certo (“we”, “us”, or “our”) is operated by AQM BD PTE LTD (UEN 202411138W), a company registered in Singapore. This Privacy Policy explains how we collect, use, and protect your personal information when you use our platform at oprecocerto.pt and our mobile application.

1. Information We Collect

• Search queries: We log product searches to improve search relevance and understand consumer interests.
• Barcode scans: When you use the barcode scanner feature, we access your device camera temporarily to read barcodes. The camera feed is processed locally and is not stored or transmitted — only the decoded barcode number is sent to our servers to look up product information.
• Browsing data: We collect anonymous usage analytics including pages visited, time on site, and device type.
• Account information (B2B users): If you register for a business account, we collect your name, email, company name, and an encrypted password.
• API usage: For API customers, we log request counts and endpoints for billing and rate-limiting purposes.

2. How We Use Your Information

• To provide price comparison data across Portuguese and Spanish retailers.
• To process barcode lookups and return product pricing information.
• To improve search accuracy and product matching.
• To generate aggregated market insights and price trend analytics.
• To manage business accounts and API access.

3. Camera Access

Our barcode scanner feature requests access to your device camera. This access is used exclusively for reading product barcodes. The camera feed is processed in real-time on your device and is never recorded, stored, or transmitted to our servers. Only the decoded barcode number is sent to look up pricing data. You can deny camera access and still use the app by manually entering product names or barcodes.

4. Third-Party Services

We use the following third-party services that may process your data:

• Hosting infrastructure: Our servers are hosted on secure infrastructure with encrypted connections.
• Analytics: We use privacy-respecting analytics to understand usage patterns in aggregate.

5. Cookies

We use essential cookies for session management and language preference (Portuguese/English). We do not use advertising or third-party tracking cookies.

6. Data Retention

Search queries and analytics data are retained in anonymized form. Business account data is retained for as long as your account is active. You may request deletion of your account and data at any time.

7. Data Security

We implement appropriate security measures including encrypted connections (HTTPS), hashed passwords, API key authentication, and secure database practices.

8. Your Rights

You have the right to:

• Access the personal data we hold about you.
• Request correction of inaccurate data.
• Request deletion of your data and account.
• Revoke camera permissions at any time through your device settings.
• Opt out of analytics tracking.

9. Children’s Privacy

Our service is not directed to children under 13. We do not knowingly collect personal information from children under 13.

10. 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.
