Privacy Policy

This Privacy Policy explains how OctaneZen ("we", "our", or "us") manages information when you install and use OmniConvert: Unit & Currency (the "App", Package ID: com.octanezen.omniconvert).

We are firmly committed to user privacy. OmniConvert is built with an offline-first architecture: we do not require user accounts, email sign-ups, or personal identity verification to use the application.

1 No Personal Data Collection Directly by the App

OmniConvert operates without harvesting your personal information. The App does NOT collect, store, transmit, or sell:

• Your name, email address, physical address, or phone number.
• Your contacts, call logs, SMS, or messaging records.
• Your device photos, videos, microphone recordings, or external storage files.
• Your precise real-time GPS location coordinates.

2 Offline Functionality & Local Caching

OmniConvert is designed to work completely offline for all unit conversion calculations (Length, Weight, Temperature, Area, Volume, Speed). To provide a responsive, custom experience, the App stores simple configuration settings strictly on your device using Android Room Database and Preferences DataStore:

• Saved Favorite Conversions: Your bookmarked unit pairs for one-tap offline conversion.
• Last Selected Units & Categories: Automatically remembers your previous conversion state so you can resume immediately.
• Theme Preference: Remembers your chosen Dark, Light, or Follow System theme setting.
• Decimal Precision: Remembers your selected decimal rounding preference (0–6 decimals).
• Cached Currency Exchange Rates: When online, public fiat exchange rates are cached locally in your phone's memory so you can continue converting currencies while traveling without internet access.

All local data resides exclusively within your phone's isolated application sandbox. You can permanently erase all saved preferences at any time by clearing the App data in Android Settings or uninstalling the App.

3 Third-Party Services (Google Play & Google AdMob)

To support ongoing development and distribution, the App utilizes trusted third-party services provided by Google LLC. These services may process pseudonymous, non-personally identifiable technical information in accordance with their independent privacy policies:

• Google Play Services: Enables core application updates, security verification, and platform integrity checks.
• Google AdMob: Displays banner, interstitial, or app open advertisements. To deliver relevant ad content, prevent fraud, and measure ad performance, Google AdMob and its advertising network partners may collect:
  • Mobile Advertising Identifiers (such as Google Advertising ID / GAID).
  • IP address (used to determine coarse geographic location at the country/city level).
  • Device technical information (device model, operating system version, screen resolution, carrier).
  • Ad diagnostic data (impressions, clicks, and load performance metrics).

4 Children's Privacy (COPPA Compliance)

OmniConvert is designed as a general-purpose mathematical and conversion tool suitable for all audiences. The App is not directed to children under 13 years of age (or under 16 in the European Economic Area). We do not knowingly solicit or collect personal information from children.

If you are a parent or legal guardian and believe that your child has inadvertently provided personal data through a third-party service integrated into the App, please contact us immediately, and we will take prompt corrective action.

5 GDPR & International Privacy Rights

If you are an individual located in the European Economic Area (EEA), the United Kingdom, or Switzerland:

• You have the right to access, rectify, or request deletion of any data held about you. Because OmniConvert stores your preferences locally on your physical device, you maintain direct, sovereign control over your data at all times.
• Where required by the EU General Data Protection Regulation (GDPR), consent for personalized advertisements is gathered through certified Consent Management Platforms (CMP). You can revoke or modify your ad choices at any time via in-app ad options or your Android device settings.

6 Changes to This Privacy Policy

We may update our Privacy Policy periodically to reflect app improvements, security enhancements, or legal standards. Any revisions will be published on this page with an updated "Effective Date". We encourage you to review this policy periodically.
