Privacy Policy
Effective Date: July 25, 2026
Welcome to Calculator Universe, developed by SmartAI Labs ("we", "our", or "us"). We respect your privacy and are committed to protecting it. This Privacy Policy explains our practices regarding the collection, use, and disclosure of information when you use our mobile application and web utility ("Calculator Universe").
Calculator Universe is designed as an offline-first utility app. All calculations—including EMI, SIP, GST, FD, PPF, Health, Math, and Tech tools—are performed entirely locally on your device.
We do not collect, transmit, store, or process any of your personal calculator inputs or calculation results on SmartAI Labs servers. The app does not require an account or login.
To personalize the experience, Calculator Universe may store limited preferences only on your device (for example via Android SharedPreferences / browser local storage), including:
These preferences never leave your device for SmartAI Labs analytics or accounts. Clearing app data or uninstalling the app removes them. Calculator numeric inputs you type for a session are not uploaded to us.
SmartAI Labs does not collect personally identifiable information (PII) such as your name, email address, phone number, physical address, or financial account details for Calculator Universe. We do not operate user accounts or crash reporting, and the app itself contains no analytics.
On the website version only, we use Vercel Web Analytics to understand how many people visit and which calculators are used. It is a privacy-friendly, cookieless measurement tool that reports only aggregate figures (such as page views, referrers, and approximate country). It does not set cookies, does not track you across other websites, and does not collect personally identifiable information. See Vercel's analytics privacy documentation.
To support free distribution of the Android app, Calculator Universe may display advertisements via Google AdMob. The web version may use Google AdSense separately.
Google AdMob (and related Google advertising services) may collect and process device and usage information to serve ads, measure performance, and prevent fraud. This may include:
AdMob's use of data is governed by Google's policies: Google Privacy Policy and How Google uses information from sites or apps that use our services.
You can reset or limit the Advertising ID in your Android device settings (Google → Ads), subject to your OS version.
SmartAI Labs does not sell, rent, or trade user data. We do not share calculator inputs or My Calculators preferences with third parties. Data processed by Google for advertising is handled under Google's terms as an independent service provider / ad partner.
Calculator Universe is a general-audience productivity / tools utility (intended content rating: Everyone / 3+). We do not knowingly collect personal information from children under 13. Ads are served by Google and are subject to Google's child-directed / interest-based advertising policies.
Core calculator math and My Calculators preferences stay on-device. When ads load, traffic to Google uses encrypted connections (HTTPS) as provided by Google's SDKs.
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated effective date.
