Application: OmniConvert: Unit & Currency (com.octanezen.omniconvert) Developer: Cool Light • Effective Date: October 21, 2026
Strict Offline-First & Zero Personal Tracking: OmniConvert is built as a privacy-focused offline tool. We require no accounts, no sign-ups, and no passwords. Your conversion calculations, bookmarks, and unit preferences are stored exclusively on your device's local memory and are never transmitted to our servers or third-party databases.
1. Overview & Data Philosophy
Cool Light ("we", "our", or "us") respects your digital privacy. This Privacy Policy outlines how data is handled when you install and use OmniConvert: Unit & Currency (the "App") on Android.
Everyday utility tools should not monitor or profile your personal life. OmniConvert operates completely without requiring identity registration, contacts access, or cloud sync accounts.
2. Information We Do NOT Collect
OmniConvert does NOT collect, monitor, store, or sell:
Personal Identifiers: Your real name, physical address, email address, or phone number.
Device Content & Media: Your contact lists, photos, videos, microphones, or stored files.
Location Data: We do not request or track precise GPS location coordinates.
Conversion Queries: The numbers, units, and values you type into the converter are processed strictly in RAM and are never recorded or logged.
3. Data Stored Locally on Your Device
OmniConvert saves user preferences locally inside Android's sandboxed private storage (using Android Room Database and Preferences DataStore):
Unit Preferences: Remembers the last selected categories and units (e.g., Meter to Foot) for faster reopening.
Bookmarked Favorites: Stores your pinned conversion pairs for instant 1-tap recall.
Theme & Format: Remembers your chosen theme (Dark / Light / System) and decimal precision settings (0 to 6 decimals).
Cached Currency Exchange Rates: Stores current fiat exchange rates locally in encrypted storage so currency conversions continue working offline when traveling.
Note: All local preferences remain solely on your physical device and are completely removed if you uninstall the App or clear app storage via Android Settings.
4. Network Permissions & Data Usage
The App requests standard Android network permissions (android.permission.INTERNET and android.permission.ACCESS_NETWORK_STATE) strictly for two functions:
Live Currency Updates: When you open the Currency screen and internet connectivity is available, the App queries public exchange rate APIs to download current fiat conversion rates. No user identifiers or search terms are included in these requests.
Ad Delivery: To display non-intrusive advertisements supporting app development (detailed below).
5. Third-Party Services (Google AdMob & Play Services)
To support ongoing maintenance and feature development, OmniConvert includes integration with Google Play Services and Google AdMob. These services may collect technical device information and diagnostic identifiers:
Google User Messaging Platform (UMP SDK): Integrated to provide transparent consent controls for users in the European Economic Area (EEA), the UK, and specific US states in accordance with GDPR, UK GDPR, and CCPA/CPRA regulations. You may modify your consent choices at any time via device settings.
6. Advertising ID Opt-Out & Privacy Controls
You can reset your advertising identifier or completely opt out of personalized advertisements across all Android applications at any time:
Open your device's Settings app.
Navigate to Google → Ads (or Privacy → Ads on newer Android versions).
Tap "Reset advertising ID" or select "Delete advertising ID".
7. European GDPR & UK Compliance
For users located in the European Union, European Economic Area, or United Kingdom:
We process technical network requests solely on the basis of legitimate interest to provide exchange rate data.
Personalized advertising is served only where explicit consent is granted through our certified Google Consent Management Platform.
You have the right to access, rectify, or erase any personal information that third-party ad networks may maintain about your device identifier.
8. California Consumer Privacy Act (CCPA / CPRA)
For California residents:
We do not sell your personal data for monetary gain.
We do not collect sensitive personal information.
You have the right to request information about third-party sharing and opt out of targeted cross-context advertising.
9. Children's Privacy (COPPA Compliance)
OmniConvert is designed for general audiences (ages 13 and older). The App does not knowingly collect or solicit personal information from children under 13. If you believe that a child has inadvertently submitted personal data, please contact us immediately so we can remove it.
10. Security & Data Retention
Because all conversion logic and custom preferences are processed and stored exclusively inside your device's sandboxed local memory, your information benefits from Android operating system-level encryption and sandboxing protections.
11. Changes to This Privacy Policy
We may update this Privacy Policy periodically to reflect app updates or regulatory revisions. Any modifications will be posted to this page with an updated "Effective Date".
