We don't want your bank password.

There's a moment early in most personal-finance apps where the product stops talking about your money and starts asking for your bank login. It's presented as the easy part — a logo grid, a familiar login box, a reassuring padlock. Boscelli doesn't have that screen. Instead it asks what you're saving for, what it costs, and roughly what you've got. Some people find that refreshing. Others assume we just haven't built the integration yet. This is the explanation the second group deserves.

01 — What "connect your bank" actually grants
It isn't a balance. It's a standing key.

When you link an account through an aggregator, you're rarely granting access to one number. You're granting ongoing, read-level access to the account — typically including transaction history going back months or years — held by a third-party company you didn't choose and won't think about again, for as long as the connection lives. That access doesn't expire when you close the tab. It sits there, quietly renewing, until something makes you revoke it.

For a budgeting app, that's arguably a fair exchange: categorizing spending genuinely requires seeing the spending. But it means your financial life now lives in one more place — and the security of your data is only as good as the weakest company in that chain. Aggregators are a concentrated, permanently interesting target, for obvious reasons. That's not a scandal; it's just arithmetic. More copies, more surface.

So the honest question isn't "is linking safe?" It's what am I getting in exchange for handing over a standing key? For a budgeting tool, the answer is: a lot. For a projection tool, it turns out to be surprisingly little.

02 — Projection doesn't need today's balance
Which is the whole reason this trade works

This is the part that surprises people, so it's worth being concrete. Boscelli's job is to answer one question: at your current pace, will you reach this goal by this date — and if not, what closes the gap? That calculation is driven by four things: what you've saved, what you add each month, how it grows, and how long you've got.

Now notice which of those actually moves quickly. None of them. Your monthly contribution is a decision you made, not a number that drifts. Your expected return is an assumption. Your target date is a choice. And your balance — the one thing a bank sync would keep live — changes by roughly one month's contribution per month. On a five-year goal, a balance that's three weeks stale moves the projected outcome by a rounding error. On a thirty-year retirement goal, it's not even that.

A budgeting app needs yesterday's transactions because it's describing the past in detail. A planning tool is pointed the other way — down a runway measured in years. Live-syncing an input that barely matters, at the cost of a permanent key to your accounts, is a bad exchange rate. Boscelli declines it.

03 — The honest cost
What you give up by typing your own numbers

A case for something is worth very little if it doesn't say what it costs. So: manual entry costs you real things, and if any of these is a dealbreaker, we'd rather you know now than discover it in week two.

• Setup takes about fifteen minutes. You'll type a goal, then the balances and monthly contributions of the accounts funding it. There's no version of this where a tool reads your mind instead.
• You have to come back. Balances only update when you update them. Realistically that's a few minutes once a month — but it's a few minutes you have to actually spend.
• Nothing is categorized for you. Boscelli won't tell you where your money went last month. It isn't a budgeting app and doesn't try to be.
• Your numbers are as good as your inputs. A guessed expected return produces a projection built on a guess. We'd rather show you a clear number and tell you what it assumes than hide the assumption behind an integration.

What you get back is narrow and, we'd argue, worth it. Boscelli never holds a credential that could reach your money. There's no connection to revoke, no token to leak, no aggregator in the middle. If our database were breached tomorrow, an attacker would learn that someone is saving for a kitchen — not how to get into the account it's in. That's a meaningfully smaller blast radius, and it's a direct consequence of not asking.

04 — The part nobody expects
Typing it yourself is where the plan becomes yours

Here's the argument we're least sure of, offered as an observation rather than a finding: the fifteen minutes may be doing something useful.

An auto-synced dashboard is something that happens to you. You open it, numbers have moved, you nod, you close it. Typing your own figures — deciding what the goal actually costs, admitting what you're really contributing, choosing a date — is a different act. It's the difference between reading a weather report and packing for a trip. The monthly check-in stops being a notification and becomes a small, deliberate moment where you look at the thing you're building and decide whether the pace is still right.

We're not going to pretend friction is a feature in general. Most friction is just friction. But this particular friction sits exactly where the thinking should happen, and we've stopped apologizing for it.

05 — Where the line actually is
Not a stance against connection — a stance about custody

To be precise about the commitment: Boscelli holds no bank credentials, uses no aggregator, and stores no transaction history. An account here is a name, a type, a balance you entered, what you add monthly, an expected return, and — at most — the last four digits, so you can tell two accounts apart. That's the whole record. We never see, hold, or move your money, and the tool has no mechanism to. It's a planning surface, not a bank.

Would that ever change? Possibly, and here's the honest shape it would take: if bank sync ever appears, it will be optional, read-only, and off by default — an opt-in convenience for people who want it, never the front door, and never a requirement for using the product. The default will always be the one you can verify: you typed it, so you know what we have.

If you'd like to test the claim rather than take our word for it, there's a version of the projection engine on the public demo that runs entirely in your browser. No account, no sign-up, nothing saved anywhere — type a goal, watch it project, close the tab. It's the same math the product runs. That page exists precisely because "trust us" is a weak argument and "check for yourself" is a strong one.

Boscelli is a personal planning tool, not a registered investment adviser. Projections are estimates for planning purposes only and do not constitute financial advice.
