Privacy Policy — SoloBill

Effective July 24, 2026

1. Who we are

SoloBill (an invoice & estimate maker for freelancers and small businesses) is developed by Miber Sistemas LTDA (CNPJ 67.272.059/0001-00), based in Brazil and available worldwide on the Google Play Store, with an optional Premium subscription.

2. What data the app collects

SoloBill works offline. Everything you create — invoices, estimates, clients, products/services, categories, your business profile and logo — is stored only on your device (using Hive and SharedPreferences). We do not operate a server that receives or stores this content, and we never sell your data.

Data processed by third-party SDKs bundled in the app:

• Google AdMob (ads in the free version): advertising identifier and usage data, as described in Google's advertising policy. See section 5 for consent.
• Google Play Billing: processes the Premium subscription purchase. Payment is handled entirely by Google; we never see your card details.
• Google Firebase Analytics: collects app usage and device identifiers, sent to Google, so we can understand usage and improve the app, per Google's privacy policy.
• Google Firebase Crashlytics: collects crash and diagnostic reports, sent to Google, to help us fix stability issues. It does not include the business data you enter in the app.

3. Android permissions

• INTERNET: for ads and Google Play Billing.
• POST_NOTIFICATIONS: to show reminders you schedule (e.g. due invoices).
• RECEIVE_BOOT_COMPLETED & VIBRATE: so reminders survive a reboot and can alert you.
• BILLING: for the Premium purchase.

Choosing a business logo uses the system photo picker; the selected image is stored locally and only embedded in the PDFs you generate. The app does not request access to your contacts, location, or full photo library.

4. Documents, sharing and local backup

Invoices, estimates and receipts are generated as PDFs on your device, offline. When you tap share/export, the file is handed to Android's standard share sheet and you choose where it goes (email, WhatsApp, Drive, etc.) — nothing is sent automatically.

Backups (and any Excel/CSV exports) are created as files on your device and shared only when you choose to. We do not use any cloud account for backup.

5. Advertising & consent

In regions that require it (the EEA/UK under GDPR, and applicable U.S. states), SoloBill shows a consent request managed by Google's User Messaging Platform (UMP) before displaying personalized ads. You can review or change your choice at any time via More → Privacy options inside the app. Where consent is declined or not required, ads may be non-personalized.

6. Your rights & data deletion

Because your business data never leaves your device, you are always in control of it. To delete everything, uninstall the app or use Settings → Apps → SoloBill → Clear data on your device. For data processed by Google (ads/analytics/crashes), you also have rights under the GDPR (access, deletion, objection) and the CCPA/CPRA (including the right to opt out of the “sale/share” of personal information) — exercised through the in-app privacy options above and your device's ad-personalization settings. Questions? Contact us (section 9).

7. Children

SoloBill is a business tool and is not directed to children under 13 (or under 16 in the EEA). We do not knowingly collect data from children.

8. Changes to this policy

We may update this policy. The date at the top always reflects the current version.
