Privacy Policy

Last updated: March 2026

At InstantInvoice.io, we take your privacy seriously. This Privacy Policy explains what data we collect, how we use it, and the choices you have when interacting with our website and tools.

1. Information We Collect

A. Information You Provide

• Business name, email, and contact details you enter in invoices.
• Payment and billing information (for premium features).
• AI prompts and content you generate in the invoice tool.

B. Automatically Collected Information

• Device type, browser, IP address (for analytics & security).
• Usage events (buttons clicked, pages visited, errors).
• Session performance, load speed, and feature interactions.

C. Cookies & Tracking

We use cookies and analytics (such as PostHog) to improve product performance, user experience, and reliability. No personal data is sold or shared with third-party advertisers.

2. How We Use Your Information

We use collected data to:

• Create and store invoices you generate.
• Improve the AI model output and invoice accuracy.
• Provide customer support and technical assistance.
• Enhance site functionality and optimize performance.
• Prevent fraud and maintain security.

3. How Your Data Is Stored

All data is stored securely using modern cloud infrastructure. Invoice data is never made public and is only accessible to you.

4. Guest Data & Local Storage

If you use InstantInvoice.io without creating an account (as a guest), your invoice and business data is stored locally in your browser using localStorage. This data never leaves your device unless you sign up and choose to migrate it to your account.

• Guest data is encrypted at rest using AES-256-GCM encryption. The encryption key is stored in a secure, HTTP-only cookie that cannot be accessed by JavaScript.
• This protects your data from cross-site scripting (XSS) attacks — even if malicious code runs in your browser, it cannot read your stored invoices.
• If you clear your browser cookies, the encryption key will be lost and previously encrypted guest data will become unreadable. You can still create new invoices by upgrading to pro or creating a free account.
• When you create an account, your guest data is decrypted locally, transmitted securely to our servers, and then removed from localStorage.

5. Sharing of Information

We do not sell your data. We may share information only with:

• Service providers that help operate InstantInvoice.io.
• Analytics and error monitoring tools.
• Legal authorities if required by applicable law.

6. Data Retention

Invoice data you generate may be stored for functionality unless you delete it. You may request deletion of all associated data at any time.

7. Your Rights

You may request at any time:

• Access to your stored data
• Correction of inaccurate information
• Deletion of your account/data
• Export of your stored invoices

8. Children's Privacy

InstantInvoice.io is not intended for use by individuals under 13 years of age. We do not knowingly collect personal data from children.

9. Changes to This Policy

We may update this Privacy Policy as our services evolve. Updates will always be reflected on this page with a revised date.
