4D Wealth is built so that as little of your data as possible leaves your phone, and none of it is sold.
Expenses you type, tasks, goals, sleep, meals, water, steps, weight, check-ins and settings are stored on your device. Steps, sleep and weight can come from Apple Health with your permission; the app reads them and does not write to Health.
If you connect a bank, Plaid provides read-only transaction and balance data. Your bank login happens on the bank's or Plaid's own screens; 4D Wealth never sees it. Transactions are stored on our server (Google Firebase, United States) under an anonymous user ID so that reports can be prepared overnight. Access tokens never reach the phone.
To write briefs, reports and coach answers, a summary of your numbers (amounts, categories, payee names, plan items) is sent to the AI provider we use (currently Google Gemini) together with your language choice. It is not used to train models. Card numbers, bank logins and account numbers are never sent.
No advertising, no selling or sharing of personal data, no tracking across other apps, no moving of money.
The app uses an anonymous Firebase account — no email or password. In the app, Profile → Clear all data erases everything stored on your phone and, in the same step, everything held for you on our server: every bank link is revoked at Plaid and the records are deleted. Deleting the app removes what is on the phone.
Purchases are handled entirely by Apple. 4D Wealth never sees your card or payment details, and no third-party subscription service receives your data.
