Plan your month. Stick to it.
Craft My Budget is a free envelope-budgeting app for personal finance. The envelope method is a simple idea: at the start of each month you decide, up front, how much of your income goes to each spending category (rent, groceries, dining, savings, and so on). As the month goes, every expense reduces the matching envelope's balance — so at any moment you know exactly how much is left for each thing.
"1200 groceries" or "uber 250" — the app's natural-language parser figures out the envelope.
Sign-in is handled by Google Sign-In. The app requests one Google API
scope: https://www.googleapis.com/auth/drive.appdata. This is the most
restrictive Drive scope Google offers — it lets the app read and write inside a
single private folder called the appDataFolder, which sits inside
your own Google Drive.
What goes there: a single JSON file containing your budget — envelopes, allocations, transactions, and settings. That's it.
The appDataFolder is sandboxed by Google: it is visible only to
Craft My Budget — not to other apps you've connected, not to anyone you share
files with, and not to us. We have no server-side database holding your budget. Your
financial data never touches our servers — it goes directly between your device and
your own Drive.
You can revoke Craft My Budget's access (and delete the appDataFolder) at any
time from
myaccount.google.com/permissions.
Full details — including the exact data fields, retention, and deletion procedure — are
in the Privacy Policy.
Built originally for Indian salaried professionals who want the power of envelope budgeting without the complexity or cost of traditional finance tools, but it works anywhere with any currency.
Free. No subscription, no bank linking, no ads, no selling of data. The project is self-funded.
