Calculator & Converters ("the app") is a calculator, unit and currency converter, tip splitter and voice-input utility. We collect as little as possible. The app does not require an account, does not sell your data, and uses no AI/LLM service.
We do not directly collect personal information such as your name, email, or contacts. The following data is processed through the third-party services the app uses:
| Data | Purpose | Service |
|---|---|---|
| Usage / app-interaction data and general device info (model, OS version) | Understand usage and improve the app | Google Firebase Analytics |
| Crash & diagnostic data (crash logs, device state at the time of a crash) | Diagnose and fix crashes | Google Firebase Crashlytics |
| Advertising ID and ad-interaction data (ad views/clicks, approximate IP-based region) | Display advertising | Google AdMob |
| Currency conversion requests (a request to fetch current exchange rates — no personal data) | Provide live currency rates | open.er-api.com |
The microphone is used only while you actively use the voice-input button, to convert your speech into a calculation. Speech is processed by your device's built-in speech-recognition service. The app does not record, store, or transmit audio.
To operate and improve the app, fix crashes, and display advertising. We do not use your data to build a personal profile and we do not sell it.
Data is processed by the third-party providers listed above under their own privacy policies:
Where required, the app shows a Google-certified consent form (User Messaging Platform) before serving personalized ads, letting you accept or decline.
The app uses the Android Advertising ID for ads. You can reset or delete it in your device settings (Settings → Privacy → Ads), which limits ad personalization.
The app is not directed to children under 13 (or the minimum age in your region). We do not knowingly collect data from children.
Analytics and crash data are retained per Google's defaults. To request access to or deletion of data associated with your device, contact sajjithkumar4877@gmail.com. You can also clear the app's data from your device settings at any time.
Data is transmitted over encrypted (HTTPS/TLS) connections.
We may update this policy; the "Effective date" above will change accordingly.
