Expense tracking

Most money does not disappear in one dramatic purchase. It leaves in small, repeating amounts that stopped registering as decisions — a subscription renewed for the fourth year, a convenience fee charged every time, an autopay mandate nobody remembers authorising. Individually each is too small to argue with. Together they are often the difference between saving something and saving nothing.

These posts read the actual documents where that money shows up: credit card statements line by line, recurring mandates, and the categories that spending falls into once it is sorted properly. The arithmetic is worked in rupees on Indian salaries, and every figure is sourced to a named publication rather than a round number that sounds right.

The second half of this category is about where the record comes from, because that decides how much of your spending a tracker can see and how much access it needs to see it. In India the usual method is reading the SMS inbox, which works on Android and does not exist on iOS, and which grants an app every message including your one-time passwords. Reading the transaction alerts your bank emails you is the alternative, and it sees the same payments without ever touching an OTP. The posts here set out what each method captures, what it misses, and what it costs you in access.

That choice matters more than the feature list on any app's store page. A tracker that needs your bank login sees everything and can, in principle, do more than read. One that reads mail is limited to what the bank chose to tell you, which is a smaller set of data and a much smaller amount of trust to hand over. Knowing which one you are installing is the practical takeaway from this category.
