# What is Passbook and how does it work?

Managing a family’s financial life often means dealing with scattered
spreadsheets, separate investment accounts, insurance policies, and important
records that only one person knows how to find.




Passbook brings your family’s wealth, records, and important information
together in one private, organized place.




Here is how Passbook helps you manage your financial life.


TRACK YOUR ENTIRE WEALTH IN ONE PLACE

Most tracking tools only look at stock market investments.



Passbook lets you track everything you own and owe—including mutual funds,
stocks, ETFs, real estate, gold, cash, fixed deposits, loans, EMIs, and
insurance policies.



Instead of an isolated investment dashboard, you see your family's complete
financial picture.


KEEP IMPORTANT RECORDS ALONGSIDE YOUR FINANCES

Financial assets don't exist in a vacuum.



Passbook includes a Vault to store documents, passwords, notes, and important
instructions right next to the assets they belong to.



Whether it is a property deed, an insurance policy document, or account
credentials, your family has immediate context when they need it most.


YOUR FINANCIAL DATA STAYS ON YOUR DEVICE

Passbook is built local-first. Your financial database is encrypted and stored
directly on your computer.



When you sync your data, encrypted backups are sent directly to your personal
Google Drive.



Passbook does not store your financial portfolio data on central servers,
ensuring your sensitive records remain private and under your control.


ACCESS YOUR INFORMATION ACROSS DEVICES

You can manage your information using the Passbook desktop app and access a
read-only view of your records through the browser web app.



When using the web app, your encrypted database is retrieved directly from your
Google Drive and decrypted safely inside your browser’s memory.



Your financial portfolio data never routes through Passbook’s servers to make
cross-device access work.


WHAT DOES THIS MEAN FOR YOUR FAMILY?

Passbook gives your family a single, secure place to understand your assets,
organize important documents, and ensure that critical financial information is
never lost in scattered folders or single-person knowledge.



You get the convenience of a modern financial manager while keeping full
ownership and control of your data.
