Back to Nail App All Privacy Policies

1. Introduction

The Nail mobile application ("Nail", "the Super App") is provided by Nail Technologies Limited ("we", "us", "our"). We respect your privacy and describe below what information we collect, how we use it, and how to contact us.

Please read this policy together with any in-app disclosures. By using Nail you acknowledge this policy applies to your use of the App.

2. Information We Collect

Depending on how you use the App, your settings, and active integrations, we may collect:

  • Account registration details (such as username, email address, profile picture, and telephone number required for identity verification)
  • Communication content: Message body, voice notes, and media attachments are encrypted in transit and stored securely. If configured with end-to-end encryption, only you and the recipient can read them.
  • Financial data: Transaction metadata (transfers, wallet deposits, invoices, requests) when using banking or wallet nodes
  • Device specifications (OS version, device identifiers, and crash logs) to run securely and troubleshoot issues
  • Technical telemetry data as described in this policy

3. How We Use Information

We process information to:

  • Deliver messaging features, ensure real-time chat delivery, and provide secure media attachments
  • Process financial transfers, manage wallet balances, and reconcile transactional histories
  • Verify identities and secure accounts against fraud, spam, or unauthorized access
  • Provide technical troubleshooting and monitor app stability using Sentry or Firebase
  • Adhere to legal, anti-money laundering (AML), and regulatory requirements for financial data

4. Legal Bases (where applicable)

Where GDPR or similar regimes apply, we rely on performance of contract (to deliver chat and finance services), legitimate interests (security and improvement), compliance with regulatory obligations, and explicit consent for optional features.

5. Financial Regulations & Payments

Nail Super App integrates digital wallet infrastructure. Transaction processing is completed in compliance with local regulations and in partnership with licensed payment processors or partner banks.

We do not store your full debit/credit card numbers directly on our backend servers. Payment cards are securely handled by payment gateways and App Store mechanisms.

6. Messages & Media Data Handling

For standard chats, messages are delivered via encrypted connections. For chats configured with End-to-End Encryption (E2EE), message text and media payloads are encrypted with keys held only on user devices; we do not store decrypted message contents on our servers.

Attachments and shared files may be cached temporarily on secure servers to facilitate offline delivery and sync across multiple devices.

7. Cookies & Webviews

The native App primarily communicates with authenticated servers. Webviews embedded inside Nail (such as external help documentation) may use cookies or tracking elements governed by those third-party services.

8. Analytics and Diagnostics

We may use analytics engines (such as Firebase Analytics) or error logging platforms (such as Sentry or Crashlytics) to compile aggregate usage telemetry and fix bugs.

9. Sharing of Information

We do not sell personal datasets. We share information only under these conditions:

  • With partner financial institutions or verification bureaus required to process transfers or complete legally-mandated KYC (Know Your Customer) checks
  • With service providers that host our databases, handle server routing, or manage notifications
  • Under legal warrants, regulatory audits, or search commands issued by legal authorities

10. International Transfers

Server hardware and payment processors may route requests globally. When data is transferred internationally, we implement approved contractual clauses to ensure protection matches our standard policy.

11. Data Retention

Financial ledger histories are stored as required by financial regulations (often up to 5-7 years).

Chats, message metadata, and files are retained while your account remains active or until deleted by you.

Telemetric logs are cleared on rotation schedules unless required for ongoing security reviews.

12. Security

We secure communication channels with Transport Layer Security (TLS) and utilize strong server encryption.

Users are responsible for securing their account verification pins, passwords, and devices.

13. Your Rights

Depending on local laws, you have rights to access, update, correct, download, or request deletion of your messaging profile or transaction accounts. Contact us to submit a request.

14. Children's Privacy

Due to integrated financial features, Nail Super App is designed for individuals of legal age to hold financial accounts. We do not intentionally compile information from children. If you believe we have received details from a minor, notify us immediately.

15. Third-Party Services, Changes & Contact

Nail Super App integrates third-party tools for diagnostics. Please review their statements:

Integrations may update with app revisions. New versions of this policy will replace older guidelines.
