This privacy policy governs your use of the software application UPI QR Calculator (“Application”) for mobile devices and our website https://esparx.in (“Website”), which were created by esparx.in (“we,” “us,” or “our”).
The Application is an instant billing calculator and UPI QR code generator designed specifically for shop owners and merchants. We are committed to protecting your privacy and ensuring you have a secure experience.
1. Information We Collect
A. Personal Data
We do not require you to register an account, log in, or provide personal identification information (such as your name, email address, or phone number) to use the core features of the Application.
B. Financial Data
The Application operates locally to calculate billing amounts and generate UPI QR codes or payment links.
- We do not collect, store, or transmit your bank account details, UPI PINs, or transaction histories.
- The UPI IDs you input to generate QR codes are stored locally on your device and are only used to form the standard payment string required for scanning.
C. Automatically Collected Information & Device Permissions
To function properly, the Application may request specific device permissions:
- Network/Internet Access: Required to load third-party advertisements and access our website services.
- Storage/Media Permissions: Required if you choose to save or share generated QR codes or payment links with your customers via third-party apps (e.g., WhatsApp).
2. Third-Party Services and Advertisements
To keep this Application 100% free for shop owners, we display third-party advertisements. These third-party services may collect information used to identify your device.
Google AdMob
We use Google AdMob to serve advertisements within the Application. Google AdMob may collect and use pseudonymous data (such as your device’s advertising ID, IP address, and device type) to serve personalized or non-personalized ads, prevent fraud, and analyze ad performance.
For more information on how Google uses your data, please review:
- Google Privacy & Terms
- How Google uses information from sites or apps that use our services
3. Data Storage and Security
We value your trust in providing us your information. Since the Application operates primarily offline and stores configuration data (like your business UPI ID) locally on your mobile device, your data remains in your control. We do not host your transaction or calculation data on our servers.
Please note that no method of transmission over the internet, or method of electronic storage, is 100% secure and reliable, and we cannot guarantee its absolute security.
4. Children’s Privacy
These Services do not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13 years of age. If we discover that a child under 13 has provided us with personal information, we immediately delete this from our servers.
5. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. Thus, you are advised to review this page periodically for any changes. We will notify you of any changes by posting the new Privacy Policy on this page and updating the “Last Updated” date at the top.
