Privacy Policy for Nine Star Technologies

Last Updated: October 2026 • Compliant with Google Play Developer Policies, GDPR & CCPA/CPRA

This Privacy Policy explains how Nine Star Technologies ("we", "us", "our", or the "Company") collects, uses, processes, discloses, and protects your personal and technical information when you visit our website (https://ninestar-portal.vercel.app or any official custom domain), communicate with us, or install, download, and interact with any mobile applications, APIs, or software published by Nine Star Technologies on the Google Play Store (collectively, the "Services").

By accessing our website or installing and utilizing our applications, you agree to the collection and use of information in accordance with this Privacy Policy. If you do not agree with this policy, please refrain from accessing our website or using our mobile applications.

1. Information We Collect

We collect only the minimum amount of information necessary to deliver, maintain, secure, and enhance our Services.

A. Information You Voluntarily Provide to Us

  • Contact & Support Details: When you contact our support team via email, contact forms, or communication channels, we collect your name, email address, and the specific details/attachments of your query.
  • Account Information: For applications supporting cloud synchronization or user accounts, we collect account credentials (such as your email address, display name, and securely hashed passwords) managed through authentication providers like Supabase Auth or Firebase Auth.
  • User-Generated Content: If you utilize our financial, ledger, utility, or productivity tools, data you enter (such as records, calculations, or offline entries) is stored either locally on your device or securely synced to encrypted cloud databases if you opt-in to cloud sync.

B. Information Collected Automatically

  • Device & Technical Data: We and our third-party analytics providers may collect technical information about the device you use, including device model, operating system version, unique device identifiers (Android Advertising ID, AAID), network carrier, IP address, and system language.
  • App Performance & Diagnostics: Diagnostic logs, crash reports (Crashlytics), app launch timestamps, interaction flows, ANR (Application Not Responding) metrics, and API latency measurements.
  • Cookies & Local Storage: Our website may use lightweight session cookies or local storage strictly for essential site functionality, theme preferences (light/dark mode), and secure administrator sessions.

2. How We Use Your Information

We process personal and technical data for the following lawful and legitimate business purposes:

  • Operating Our Services: To provide, execute, optimize, and maintain the functionality of our website and mobile applications.
  • Product Improvement & Analytics: To diagnose bugs, analyze usage patterns, monitor crash logs, and improve user interface and computational performance.
  • Customer Support: To answer your inquiries, investigate user-reported technical issues, and provide timely software patches.
  • Legal & Policy Compliance: To comply with applicable laws, respond to lawful governmental requests, resolve disputes, and enforce our Terms and Conditions.
  • Security & Fraud Prevention: To protect against unauthorized access, malicious attacks, reverse engineering, and policy violations.

3. Third-Party Services & SDK Integrations

Our website and mobile applications integrate with carefully vetted, industry-leading third-party service providers. These services process data under their own independent privacy policies:

  • Google Play Services & Google Play Billing: Used for distribution, core platform APIs, and digital purchase/subscription processing.
  • Supabase (Supabase Inc.): Used for scalable PostgreSQL databases, user authentication, and secure data storage.
  • Google Analytics for Firebase & Crashlytics: Used to understand crash events and real-time app stability.
  • Google AdMob (for Ad-Supported Apps): Some free tiers may serve personalized or non-personalized advertisements. Google AdMob may use your device's Android Advertising ID (AAID) to deliver contextually relevant advertisements in strict compliance with Google Play Families and Advertising Policies.
  • Hosting Platforms (Vercel / Cloudflare): Used to deliver global content with automated SSL and edge caching.

We do not control and are not responsible for the privacy policies of external websites or third-party SDKs beyond our reasonable security assessments.

4. Children’s Privacy (COPPA & Google Play Families Policy)

Our website and general software applications are intended for a general audience. We do not knowingly collect, solicit, or retain personally identifiable information from children under the age of 13 (or 16 in the European Economic Area).

If a specific application published by Nine Star Technologies is targeted at or accessible to families/children:

  • It will explicitly declare its Target Audience in its Google Play Console listing.
  • It will not transmit personal identifiers or transmit non-certified ad SDK requests.

If we discover that personal data has been inadvertently collected from a child without verified parental consent, we will immediately delete that information from our servers.

5. Data Retention and Security

  • Data Retention: We retain personal information only for as long as necessary to fulfill the purposes outlined in this Privacy Policy, provide ongoing support, or comply with legal obligations.
  • Security Measures: We implement industry-standard organizational and cryptographic safeguards, including HTTPS/TLS encryption in transit, strict database Row Level Security (RLS), and principle-of-least-privilege access controls.
  • Limitation: While we employ robust security practices, no method of transmission over the Internet or electronic storage is 100% secure, and we cannot guarantee absolute security.

6. User Rights & Data Deletion (GDPR & CCPA/CPRA Compliance)

Depending on your jurisdiction (including the EU, UK, and California), you possess specific legal rights regarding your personal information:

  • Right to Access: You may request confirmation of whether we process your data and obtain a copy of it.
  • Right to Rectification: You may request correction of inaccurate or incomplete personal information.
  • Right to Deletion (Right to Be Forgotten): You have the absolute right to request the permanent deletion of your account and associated personal data from our systems.
  • Right to Opt-Out: You can reset or opt out of personalized advertising tracking at any time through your Android device settings (Settings > Google > Ads > Delete advertising ID).

How to Request Account or Data Deletion: To request complete deletion of any data held by Nine Star Technologies, email our Data Privacy Officer at support@ninestartech.com with the subject line "Data Deletion Request". We will process verified requests within 30 days without undue delay.

  • It is comprehensively accessible via an active, publicly available URL with no geo-restrictions or paywalls.
  • It details all runtime permissions requested by our applications (such as internet access, notifications, or camera/storage if applicable to specific utilities).
  • We strictly adhere to Google’s Prominent Disclosure and User Consent requirements for any sensitive or on-device data access.
