Privacy Policy

Last Updated: February 03, 2026

1. Introduction

Welcome to Invoice Maker App ("we," "our," or "us"). We respect your privacy and are committed to protecting your personal data. This Privacy Policy explains how we collect, use, store, and safeguard your information when you use our mobile application (the "App").

Unlike traditional cloud-based invoice generators, our App operates on a "Local-First" architecture. This means your sensitive business data resides primarily on your device, giving you greater control and privacy.

2. Data We Collect

We collect information in three categories:

A. Information You Provide Directly

  • Account Registration: When you create an account, we collect your email address and authentication ID (provided by Apple, Google, or your email provider). We do not store passwords.
  • Business Profile: Company name, logo, address, phone number, and tax identifiers (e.g., VAT, EIN).
  • User Content (Invoicing Data): Client details, item descriptions, prices, invoices, estimates, signatures, and photographic evidence of work.
  • Customer Support: Information you provide when contacting us for help.

B. Information Collected Automatically

  • Usage Data: We use tools like Amplitude and Firebase Analytics to collect anonymous data on how you use the App (e.g., screens visited, features used). This helps us improve the user experience.
  • Device Information: Device model, operating system version, and unique device identifiers (for subscription management via RevenueCat).
  • Crash Logs: We use Sentry to collect technical error reports when the App crashes. These logs help us fix bugs and do not typically contain user-generated content.

C. Device Permissions

To provide specific features, we may request access to:

  • Camera & Photo Library: To allow you to upload business logos and attach evidence photos to invoices.
  • Contacts: To allow you to easily import client details from your address book into an invoice. We do not upload your contact list to our servers; this processing happens locally on your device.

3. How We Store and Protect Your Data (Architecture)

We use a hybrid storage model to ensure data safety and privacy:

  • Local Storage (Primary): Your invoices, clients, and settings are stored locally on your device using an encrypted SQLite database. This allows the App to function offline.
  • Cloud Backup (Secondary): To prevent data loss (e.g., if you lose your phone) and to enable synchronization, we use Supabase (an enterprise-grade PostgreSQL service) to create a secure backup of your data. This synchronization occurs only when your device has an internet connection.

4. How We Use Your Information

We use your data solely for the following purposes:

  • To provide, operate, and maintain the App.
  • To process transactions and manage your subscription via RevenueCat.
  • To authenticate your identity and prevent fraud.
  • To monitor usage trends and improve App stability.
  • To comply with legal obligations.

5. Data Retention and Deletion

You retain full ownership of your data.

  • Account Deletion: You may request account deletion directly within the App settings.
  • 30-Day Grace Period: Upon deletion request, your account enters a "Scheduled for Deletion" state. Your data remains in our secure backups for 30 days to allow for recovery in case of accidental deletion.
  • Permanent Purge: After 30 days, all your data (including invoices, images, and profile information) is permanently and irreversibly erased from our servers.

6. Sharing Your Information

We do not sell your personal data. We share data only with trusted third-party service providers required to operate the App:

  • Database & Auth: Supabase.
  • Subscription Management: RevenueCat.
  • Payments: Apple App Store and Google Play Store (we do not process or store credit card info).
  • Analytics & Stability: Google Firebase, Amplitude, Sentry.

7. International Data Transfers

Your information, including Personal Data, may be transferred to — and maintained on — computers located outside of your state, province, country, or other governmental jurisdiction where the data protection laws may differ. We take all steps reasonably necessary to ensure that your data is treated securely.

8. Your Rights (GDPR & CCPA)

Depending on your location, you may have rights under the GDPR (Europe) or CCPA (California), including:

  • The right to access, update, or delete the information we have on you.
  • The right to object to the processing of your data.
  • The right to data portability (exporting your data).

9. Children's Privacy

Our Service does not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children.

10. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. You are advised to review this page periodically for any changes.
