Nudge InvestPrivacy is the architecture, not a setting
Your data never leaves your phone
Holdings, transactions and your FX table are stored locally, behind a 4-digit PIN and biometric app lock.
No account, no tracking, no ads
There is nothing to sign up for and no profile to create. The app carries no ad slots.
Works on a plane, in a vault, anywhere
The tracker runs fully offline. Open it with no signal and every number is still there. Why this matters →
Everything you own, one screen
Stocks, ETFs & funds
Unlimited assets and transactions, with cost basis and average buy price on every position.
Crypto & stablecoins
Coins and stablecoins sit beside your shares, each tagged with the exchange or wallet they are held at.
REITs & dividend income
Dividend income per asset and per year, plus ROI including dividends alongside plain ROI.
Real profit & loss
Realised and unrealised P&L and ROI, calculated from your own transactions and cost basis.
Multi-currency net worth
Net worth across currencies using your own FX table, so the conversion is yours and not a guess.
CSV, charts and app lock
CSV import and export, charts over your history, and a 4-digit PIN with biometric app lock.
AI Coach that reads only what you allow
Optional, off by default, and it never writes to your portfolio without an explicit Approve.
Imports broker statements from PDF, Excel, CSV or photos.
Refreshes prices and FX rates when you ask it to.
Privacy toggles decide what it can see. Nothing else is shared.
