This version has no accounts, subscriptions, in-app purchases, or ads. Calculators and articles are available without signing in.
Are prices and charts live?
No. Prices, percentage changes, charts, market summaries, and USD/IDR conversions use fixed simulated data. They illustrate screens and calculations; they must not be used as current transaction prices.
Can I trade, hold assets, or borrow money?
No. WDGZ PRO does not provide trading, wallets, deposits, loans, payments, or brokerage services. Calculator figures are educational simulations, not investment advice or guaranteed returns.
How do I change language or currency?
Open Settings. Choose Bahasa Indonesia, English, or 简体中文, then select IDR or USD as the display currency. Your choices are saved on the device. Price conversions use a fixed simulated rate; selecting a currency does not retrieve an online exchange rate.
Which number format should I use?
Indonesian uses a decimal comma, such as 1250,50 or 1.250,50. English and Chinese use a decimal point, such as 1250.50 or 1,250.50. Do not enter currency symbols. Compound-growth duration must be a whole number of years from 1 to 50.
How are fees and growth calculated?
Profit and loss applies the same fee percentage to both purchase and sale values. Net return is measured against the purchase cost including its fee. Compound growth converts an effective annual return to a monthly rate, with contributions at the end of each month. Taxes, inflation, price spreads, and other costs are excluded.
How is my watchlist saved?
Tap the star beside an asset to add or remove it. Language, currency, and watchlist preferences are stored on this device. The app does not sync these preferences to an account or another device.
How do I delete my data?
Open Android Settings → Apps → WDGZ PRO → Storage → Clear data/Clear storage, or uninstall the app. Menu labels may vary. There is no app account to delete. For deletion of support emails you previously sent, contact wdgz2789000@gmail.com. See the Privacy Policy for details about system and device-service copies.
Does the app work without internet?
Yes. Calculators, articles, and simulated screens are bundled with the app. Opening support/policy websites or sending email requires an internet connection and a suitable app.
