Unit Converter ("we", "us", or "our", developed by Shuttle Technologies) is committed to providing a reliable, fast, and completely privacy-first unit conversion utility. This Privacy Policy & Legal Disclaimer outlines our operational data policies and sets forth the terms governing your use of our application, conversion engines, financial currency feeds, and smart engineering tools.
đź”’ 100% Privacy-First Architecture: Unit Converter does NOT require account creation, does NOT collect your name, email, or personal identity, and does NOT upload your conversion inputs or historical calculations to any remote cloud database.
1. Zero Personal Data Collection
We believe in absolute privacy. Unit Converter does not collect, harvest, store, or sell any personally identifiable information (PII). When using Unit Converter:
- No account registration, user profile, or login credentials are required.
- We do not collect names, phone numbers, email addresses, contacts, or GPS location data.
- Your mathematical expressions, unit selections, and custom conversion calculations are processed strictly on-device in volatile device memory and never transmitted to our servers.
2. Internet Usage & Live Currency Rates
Unit Converter functions completely offline for 54 standard unit conversion categories. Internet access is requested strictly for:
- Live Exchange Rate Synchronization: Periodically fetching current public foreign exchange reference rates from verified financial APIs (such as European Central Bank reference feeds). These requests are fully anonymous and contain no device identifiers or personal identifiers.
- Offline Fallback: If an active internet connection is unavailable, Unit Converter operates seamlessly using locally cached exchange rates with clear status indications.
3. Local Device Storage
All application preferences are saved strictly within your device's private local sandboxed storage (Room Database & DataStore Preferences):
- Favorites & Quick Access: User-pinned categories and frequently paired unit conversions.
- Conversion History: Temporary historical records protected by smart debouncing to prevent keystroke clutter. You can clear or delete historical records at any time directly in the app.
- Theme & Display Preferences: Selected system theme (Light/Dark mode), preferred decimal precision, and UI language choice.
Uninstalling Unit Converter or clearing application storage immediately and permanently removes all locally stored preferences and history.
4. Third-Party Services & Advertising
Unit Converter is offered as a free mobile application supported by non-intrusive advertisements:
- Google AdMob: Serves standard banner and interstitial ads. Google AdMob may utilize anonymous advertising identifiers (Google Advertising ID) and non-personal diagnostic signals in compliance with Google Play Developer policies. Review Google's Privacy Policy: https://policies.google.com/privacy.
- Google Play Services: Used to maintain application integrity, deliver in-app reviews, and ensure secure software delivery.
5. Children's Privacy Protection
Unit Converter is a universal mathematical utility suitable for students, educators, professionals, and general users. We do not intentionally target, collect, or process information from children under 13 years of age (or under 16 in applicable European jurisdictions), in strict adherence to COPPA and GDPR requirements.
6. Policy Updates
We may update this Privacy Policy & Legal Disclaimer periodically to reflect new software capabilities, additional unit categories, or statutory regulatory standards. Updates will be posted on this page with an updated revision date.
Statutory Notice
⚠️ Legal & Professional Disclaimer
PLEASE READ THIS LEGAL DISCLAIMER THOROUGHLY BEFORE UTILIZING UNIT CONVERTER:
- General Informational & Educational Reference Only: Unit Converter is engineered solely as a digital reference tool for general informational, educational, and computational assistance. All unit conversions, formula calculations, visual graphs, and engineering estimations are provided in good faith.
- Not Professional Financial or Forex Trading Advice: Foreign exchange rates, currency historical charts, and currency calculations are derived from public reference feeds and are subject to market volatility, timing latency, and spread discrepancies. They do NOT constitute certified financial advice, forex brokerage guarantees, or bank-settlement rates. Always verify live market rates with an authorized financial institution or central bank prior to conducting commercial transactions, remittances, or investments.
- Not Certified Engineering or Industrial Safety Advice: Specialized calculations—including but not limited to American Wire Gauge (AWG) conductor ampacity, resistor color bands, electrical voltage/current, magnetic flux, radiation dose, structural pressure, and thermal conductivity—are heuristic mathematical estimations. They do NOT replace certified engineering calculations, architectural blueprints, or local building/electrical codes (such as NEC, IEC, or ISO standards). Never rely solely on this app for life-critical, aerospace, medical equipment, or hazardous electrical installations without independent professional validation.
- Not Clinical or Medical Advice: The Blood Sugar (glucose) converter and Nutrition Energy tools are strictly for informational and unit conversion purposes. They do NOT constitute clinical diagnostic advice, treatment plans, or therapeutic prescriptions. Consult a licensed medical physician, endocrinologist, or registered dietitian for medical diagnosis, diabetes management, or clinical health decisions.
- Apparel & Sizing Estimations: Clothing, shoe, ring, and hat size conversions represent standard international sizing equivalents (US, UK, EU, JP, CM). Actual garments and footwear vary significantly between manufacturers, designers, and regional cutting standards.
- "AS IS" Software Warranty: While we rigorously test and maintain conversion constants against international standards (BIPM, NIST, SI), Unit Converter is provided strictly on an "AS IS" and "AS AVAILABLE" basis. Shuttle Technologies makes no express or implied warranties regarding calculation accuracy, uninterrupted operation, or zero error margin.
- Limitation of Liability: In no event shall Shuttle Technologies, its founders, contributors, or developers be held liable for any direct, indirect, incidental, consequential, special, punitive, or financial losses, damages, or injuries resulting from the use of, or inability to use, any conversions, calculations, or features provided by Unit Converter.
