Privacy Policy

This page is maintained by GridFiller to answer common security and privacy questions about the app. It is not an independent certification or legal advice.

1. What this policy covers

This Privacy Policy describes how GridFiller collects, uses, stores, and shares information when you use our website and services. It applies to visitors, registered users, and paying subscribers.

2. Data we collect

• Account data: email address, display name, authentication provider details, and payment-related identifiers (such as a Stripe customer ID).
• Files and generated data: images, PDFs, screenshots, and the spreadsheets extracted from them. These are stored so you can view, edit, and export them later.
• Usage data: app interactions, conversion counts, and error logs to help us operate and improve the service.
• Cookies and local storage: authentication tokens, theme preferences, and cookie-consent choices.

3. How we use your data

We use your data to provide, secure, and improve the service: processing files, managing your subscription and credits, authenticating you, and communicating about your account.

We do not sell your personal data or your uploaded files. We may share limited data with trusted service providers described below.

4. Subprocessors and integrations

GridFiller relies on the following service providers to host, process payments, and run AI extraction:

• Lovable Cloud / Supabase: authentication, database, file storage, and hosting infrastructure.
• Stripe: payment processing and subscription management.
• Lovable AI Gateway / Google Gemini: document analysis and spreadsheet extraction.

The security and availability of these providers are part of their shared responsibility model. GridFiller configures their features for privacy and access control, but each provider is responsible for its own platform security.

5. Cookies and analytics

We use essential cookies to keep you signed in and to remember your cookie preference. We may also use optional analytics cookies to understand how the product is used.

You can manage your cookie choice at any time via the cookie banner at the bottom of the page. Essential cookies cannot be disabled without signing out or clearing your browser storage.

6. Data retention and deletion

Uploaded files and conversion results are retained while your account is active so you can access them. You can delete individual files or conversions from your account. If you delete your account, we will remove your personal data and files within a reasonable period, except where we are required to keep it for legal or billing reasons.

7. Your privacy rights

Depending on where you live, you may have rights to access, correct, delete, or restrict processing of your personal data. To exercise these rights, contact us using the information below. We will respond to verified requests in accordance with applicable law.

8. Security

We apply several security controls to protect your data, including authenticated access, encrypted storage and transport, row-level database policies, and regular dependency scanning. Security is a shared responsibility: you should also keep your account credentials safe and use a strong password.

9. Children's privacy

GridFiller is not intended for children under 13. We do not knowingly collect data from children under 13. If you believe we have collected such data, please contact us.

10. Changes to this policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top of this page reflects the most recent revision. Continued use of the service after changes means you accept the updated policy.
