3. How We Use Your Information
We use your information to:

- Track estimate views and digital signatures

4. AI Processing
Master Invoice uses Google's Gemini AI to generate estimate content. When you create or edit an estimate:
- Your job description, trade type, and pricing are sent to Google's Gemini API
- Customer personal information is not sent to the AI
- Google processes this data according to their own privacy policy and terms of service
- AI-generated content is returned to the app and stored in your account
5. Data Storage and Security
Your data is stored using Google Firebase, which provides:
- Encrypted data transmission (HTTPS/TLS)
- Secure authentication with email verification
- Firestore database with security rules restricting access to your own data
- Firebase Storage for photos and logos with access controls
We implement reasonable security measures to protect your information. However, no method of electronic storage is 100% secure, and we cannot guarantee absolute security.
6. Data Sharing
We do not sell your personal information. We share data only in these circumstances:
- With your customers: When you send an estimate or invoice, the recipient sees the estimate content, your business profile, and their own information as entered by you.
- Service providers: We use Google Firebase (hosting/database), Google Gemini (AI generation), RevenueCat (subscription management), and Formspree (website form submissions).
- Legal requirements: If required by law, regulation, or legal process.
7. Email and SMS
Master Invoice uses your device's native email and SMS apps to send estimates. We do not operate email or SMS servers. Messages are sent directly from your device using your own email account and phone number. We do not have access to or store copies of sent messages.

You have the right to:
- Access your data through the app at any time
- Update your profile and business information

- Delete your account by contacting us at help@masterinvoiceapp.com

9. Data Retention
We retain your data for as long as your account is active. If you request account deletion, we will delete your personal data within 30 days, except where we are required by law to retain certain information.
10. Children's Privacy
Master Invoice is not intended for use by anyone under the age of 18. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it.
11. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the new policy in the app or on our website. Your continued use of the Service after changes constitutes acceptance of the updated policy.
