Privacy Policy
This Privacy Policy explains how BillStat (“BillStat”, “we”, “us”) collects, uses, and shares information when you use the BillStat mobile application and related services (the “Service”).
1. Who operates BillStat
Operator: DevMontGroup
Website: https://devmontgroup.me
Address: Bar, Montenegro
Contact: support@billstat.app
2. What the Service does
BillStat is intended to help you track receipts in Montenegro: you scan the QR code on a receipt, confirm saving when a receipt is found, and BillStat retrieves receipt details via an official receipt verification service (the “Government Service”) and saves the receipt to your BillStat account.
BillStat is not designed to scan or process POS card slips, payment slips, or other documents that may contain bank card details. BillStat does not intentionally collect payment card numbers, CVV, or PIN.
3. Information we collect
We collect information in the following categories:
- Account information: when you sign in with Google or, on iOS, Apple, we receive provider identifiers and your email and name when supplied. Google may also supply a profile photo. We store authentication data, including provider tokens and session tokens, to support sign-in and authenticated access.
- Receipt scan information: QR code contents and/or the receipt link embedded in the QR code, and the receipt identifiers derived from it (as needed to query the Government Service).
- Receipt data stored in BillStat: receipt details returned by the Government Service (for example, merchant/tax entity information, date/time, totals, VAT, and line items when available).
- Support communications: if you contact us, we collect the content of your message and the contact information you provide.
- Operational and security data: application events, screen views, errors, crashes, network request information and technical logs used to operate and troubleshoot the Service. See section 7.
4. How we use information
We use information to:
- Provide the Service (authenticate you, scan receipts, fetch receipt details, and show receipt history).
- Maintain and improve reliability and security, prevent abuse, and troubleshoot issues.
- Respond to your support requests and communicate with you about the Service.
5. Government Service (receipt lookup)
When you scan a receipt QR code, BillStat sends receipt identifiers derived from the link in the QR code to the Government Service to retrieve receipt details. The availability and accuracy of receipt data depends on the Government Service.
6. Sharing of information
We may share information with:
- Google and Apple (authentication through your selected sign-in provider; Apple Sign-In is available on iOS).
- Government Service (receipt lookup using identifiers from the fiscal QR link).
- IRMS (merchant activity lookup using the seller tax identifier).
- Microsoft Azure Application Insights (operational telemetry described in section 7).
- Microsoft Azure Service Bus (receipt import processing; queued messages contain receipt and user identifiers, the fiscal QR URL, enqueue time and a correlation identifier).
- Service providers (hosting and database infrastructure necessary to run the Service).
- Legal and safety (if required by law, or to protect the Service and users).
We do not sell your personal information.
7. Analytics and tracking
BillStat uses Microsoft Azure Application Insights to collect operational telemetry, including application events, screen views, errors, crashes and information about network requests. We use this information to diagnose problems and improve service reliability. Operational logs may include technical identifiers and identifiers associated with accounts or receipts. This collection is separate from the spending statistics shown to you in the app.
8. Data retention
We retain your account information and stored receipts for as long as your account is active or as needed to provide the Service. Operational telemetry stored in Azure Application Insights has a configured total retention period of 90 days from collection. Deleting your BillStat account does not automatically remove this telemetry.
9. Your choices and rights
You may:
- Request access, correction, or deletion of your account data and stored receipts.
- Control device permissions (for example, camera access) via your device settings.
To delete your account and data, open the Profile tab in the app and tap Delete Account. Alternatively, email support@billstat.app. We aim to process deletion requests within 30 days.
10. Security
We use reasonable technical and organizational measures to protect information. However, no method of transmission or storage is completely secure.
11. International transfers
Your information may be processed in countries where our service providers operate. We take steps to protect information consistent with this Policy.
12. Children
The Service is not directed to children, and we do not knowingly collect personal information from children.
13. Changes to this Policy
We may update this Policy from time to time. The “Effective date” above indicates when it was last updated.
14. Contact
If you have questions about this Policy, contact us at support@billstat.app.
