1. Introduction

Welcome to Proof Invoice by Mationetic (“we”, “our”, or “us”). We respect your privacy and are committed to protecting any personal information you may share with us. This Privacy Policy outlines how we collect, use, and handle your data when you visit our website, use our mobile application, and interact with our invoice and estimate generation tools.

2. Information We Collect

We collect the following information to ensure the smooth operation of our services:

  • Account Data: When you sign in using Google, we receive basic profile information (such as your name, email address, and profile picture) to create and authenticate your account.
  • Financial Information: We offer in-app purchases and subscriptions. We do not directly collect, process, or store your payment card details. All transactions are securely handled by third-party platforms (such as the Apple App Store, Google Play Store, or our payment gateway).
  • Usage & Device Data: We may collect non-personally identifiable information such as your IP address, device type, operating system, browser type, and interaction with our platforms through standard logs and analytics tools.
  • App Permissions: Our mobile app may request specific local permissions (such as local storage for saving documents or settings). These can be managed in your device settings.

3. How We Use Your Information

Any collected data is used exclusively to:

  • Authenticate your account and sync your data securely.
  • Manage your in-app purchase subscriptions and unlock premium features.
  • Operate, maintain, and improve the user experience on our website and mobile app.
  • Analyze general traffic to understand which features are most helpful.
  • Ensure the security and integrity of our systems.

4. Security

We prioritize the security of our platform. We use industry-standard measures (including secure BaaS via Supabase) to protect our website and app against unauthorized access or data breaches.

Our application may contain links to third-party services. We are not responsible for the privacy policies or content of these third-party websites. We encourage you to read their respective privacy statements.

6. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page or within the mobile app with a revised “Last Updated” date. By continuing to use our services, you agree to the updated terms.
