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

- 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.
🔒 AES-256-GCM Encryption
- 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.
- Important: 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.

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