VoltService Ltd is the controller of personal data described in this policy. PaySmart is an invoice productivity product that helps users manage business profiles, clients, work records, and professional invoices.
This policy applies to PaySmart accounts, the Android app, our website, and support interactions. A third-party service may also act as an independent controller under its own privacy policy when you choose to use that service.
Your account identifier, name, email address, phone number, verification status, authentication provider, sign-in events, and security settings. Depending on the method you choose, this includes phone one-time-code records, email-link status, federated account identifiers, or passkey credential metadata.

If you purchase a subscription, we receive product, purchase token, order, entitlement, status, and renewal information from Google Play. We do not receive your full payment-card number from Google Play.
Support messages, notification preferences, consent choices, and communications required to operate or secure your account.
If you choose Continue with Google or link a Google account, PaySmart requests the openid, email, and profile scopes. We may receive your stable Google account identifier, name, email address, email-verification status, and profile image, depending on what Google makes available.
We access only the basic account data needed to authenticate you, link the Google identity to your PaySmart account, prefill relevant account details, show the linked sign-in method, prevent duplicate or fraudulent accounts, and help secure or recover access.
The Google account identifier and relevant profile fields may be stored with your PaySmart account in Firebase and Google Cloud. Authentication tokens are handled by the authentication service and protected through encrypted connections and access controls.
Google user data is shared only with service providers acting for PaySmart where needed for authentication, hosting, security, support, or legal compliance. We do not sell Google user data or disclose it to data brokers.
We retain linked Google account data while the PaySmart account or link remains active and remove or de-identify it when the account or link is deleted, subject to limited security, dispute, and legal retention needs.
PaySmart does not use Google user data for targeted advertising, advertising profiles, creditworthiness or lending decisions, sale to data brokers, or training general-purpose artificial-intelligence models.
PaySmart's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including its Limited Use requirements.
Create and authenticate accounts; maintain profiles; manage clients and work; create, store, export, and share invoices; provide subscriptions and support. The legal basis is performance of our contract with you.
Verify phone numbers and email addresses, link sign-in providers, detect abuse, investigate incidents, enforce access controls, and recover accounts. We rely on our contract and legitimate interests in protecting users and the service.
Diagnose crashes, measure performance, troubleshoot failed operations, and improve app features and accessibility. We rely on our legitimate interests in operating and improving PaySmart.
Send verification codes, service notices, invoice-related notifications and security alerts; respond to support; meet legal duties; and protect legal rights. We rely on contract, legitimate interests, legal obligations, or consent where required.
We do not sell personal data. We disclose only the information reasonably necessary to these recipients:
Processors acting for us must handle personal data under contractual and security obligations and may use it only to provide their services to us.
PaySmart primarily stores account and product data using Firebase and Google Cloud services. Data may be processed in countries where our providers operate. Where required, we use contractual and other safeguards for international transfers.
We use safeguards appropriate to the risk, including encrypted network connections, provider encryption at rest, authentication and role-based access controls, restricted production access, application-integrity checks, monitoring, and incident-response procedures. No internet service can guarantee absolute security, so users should also protect their device and sign-in methods.
Passkeys and device biometrics are verified by your device or platform. PaySmart does not receive or store your fingerprint, face template, device PIN, or private passkey key.
Retention can be longer where required by law, valid legal process, fraud prevention, safety, dispute resolution, or enforcement of our agreements. When information is no longer needed, we delete it or de-identify it.
To delete your account and associated data, use the in-app account deletion control, follow our data deletion instructions, or email us. We may need to verify your identity before completing a request.
PaySmart is a business productivity service and is not directed to children. We do not knowingly collect personal data from children under 13. If you believe a child has provided personal data, contact us so we can investigate and delete it where required.
We may update this policy when PaySmart's features, providers, or legal obligations change. We will publish the revised policy here, update the date above, and provide additional notice in the app or by email when a change materially affects your rights or how we use personal data.
