No Personal Information Collected:
Wealth Lab does not require user accounts, logins, or registration. We do not collect or store your name,
email address, phone number, or physical location on any server.
Local Calculation Execution:
All financial planning calculations (SIP, Lumpsum, CAGR, Inflation, SWP, etc.) are computed directly on your
mobile device. None of your input values or results are sent to remote services.
SharedPreferences Local Storage:
The app stores your preferences (theme type, custom tax rates, selected country/region, selected currency,
number system, tax presets and holding period, haptic toggles), calculation favorites, and history logs
locally on your device. This data remains private to you and is instantly cleared if you uninstall the app.
Region & Currency Defaults:
To set sensible defaults, the app reads your device's region/language setting (for example "en_US") and
stores the resulting country, currency, number system and tax preset only on your device. This value is
never transmitted to us or any server, and you can change it at any time in Settings → Country &
Currency.
Security & Data Deletion:
All calculations and history are stored locally. Since we do not transmit this data to our servers, we do
not possess a user database and cannot delete or query your records upon request. To delete all local data,
you must clear the app cache/data or uninstall the app from your device.
Sandbox Isolation Security:
Your local settings, preferences, and calculations are kept isolated from other apps on your device via the
operating system's native application sandbox (Android/iOS), ensuring local data security.
Direct Contact Inquiries:
The application itself does not solicit, require, or collect your email address or other contact
information. If you voluntarily contact us directly via email for support, we will only use your email
address and message details to address your inquiry.
Data Controller & Operator:
The developers of Wealth Lab act as the Data Controller only for any direct support emails you send to us.
We do not act as a data controller or processor for any in-app calculations or input data, as all such data
is kept strictly offline within your device's local storage.
