## What is Principal & Interest?

Principal & Interest is an offline loan decision companion for checking amounts, fees, contract terms, and next steps before signing, during repayment, and at payoff.

PRE-LOAN CHECKUPS
Use separate checklists for mortgages, car loans, and consumer loans. Answer Yes, No, or Unsure, then review neutral follow-up items. The app does not score applications or predict approval.

TRUE COST INSPECTION
Enter contract principal, actual proceeds, upfront or recurring dated fees, scheduled payments, and balloon payments. Review total outflow, proceeds gap, and an estimated annualized effective cost when a unique reliable result exists. It is not presented as a legally disclosed APR.

LOCAL LOAN PROFILES
Keep actual proceeds, fees, a prepayment-terms summary, and checklist progress on your device. Add dated events such as rate changes, normal or extra payments, fee changes, manual balances, payoff evidence, and lien release. Remaining balance, interest, and payoff projections are clearly labeled as estimates.

14 PRACTICAL PITFALL GUIDES
Review topics such as add-on costs behind “zero interest,” fee lists, balloon payments, deposits and down payments, prepayment terms, rate repricing, use restrictions, refinancing bridges, multiple borrowing, and payoff or lien-release steps. Each guide includes practical questions, fields to find, next actions, and dated sources from Chinese regulators or government bodies.

PLANNING TOOLS
Open eight clear home tasks: My Loan, True Cost, Prepayment, Refinance, Home Sale Proceeds, Affordability, Loan Check-up, and Pitfall Guide. Ten currencies use plain names and units; the app does not perform foreign-exchange conversion.

HOME SALE PROCEEDS
Choose a country or region, then enter the planned sale price, bank payoff amount, and known seller costs to estimate what may remain after an unfinished home loan is repaid. Use local rules, your contract, and the bank's current payoff quote for final figures.

PRIVACY FIRST
No account is required. Calculations and loan profiles stay on the current device. This version contains no advertising, cross-app tracking, behavioral profiling, or third-party analytics SDK. It requests no camera, location, contacts, microphone, or ATT permission.

LANGUAGES AND USER MANUAL
The interface supports Simplified Chinese, Traditional Chinese, English, Japanese, Spanish, and German. Settings has separate language, display-currency, and theme pages, plus a step-by-step visual manual covering the home screen, loan calculation, early repayment, refinancing, home-sale proceeds, checkups, guides, profiles, and settings.

Important: This app does not provide loans, submit applications, check credit, rank or recommend lenders, or sell financial products. Results are estimates for organizing contract information and are not financial or legal advice. Actual amounts, fees, and procedures depend on your contract, provider, and applicable rules.
