The hidden cost

The number that matters is the one no one shows you.

Every conversion has a real cost. Every goal has a real timeline. Every subscription is real money you keep paying. Penni surfaces what other apps quietly hide.

FX losses you never see

Your EUR→ALL transfers cost more than the mid-rate. We compare each conversion to the ECB rate and sum the difference.

Generic apps, generic advice

A €5k emergency fund means different things for different people. Penni knows your income, expenses, and goals before answering.

Calm finance, not anxiety

No streaks, no neon, no shame. Just your numbers, presented like a friend would, and an AI that talks to you, not at you.

What you get

Three things, done extremely well.

We didn't build another budgeting app. We built the parts of one we wished existed.

FAQ

The honest answers.

Real questions, no marketing fluff. Still curious? Email us.

Is my financial data safe?

Yes — and we take that seriously. Your records live in a private Postgres database with row-level security, so even our own engineers can't read them without your sign-in. Backups are encrypted, transit is HTTPS-only, and we never share or sell your data. If you leave, you take it with you.

Will Penni connect to my bank automatically?

Not in this version, and that's a deliberate choice. Manual entry is faster than you'd guess (three taps), works in every country, and keeps your credentials out of a third-party pipe. Direct bank sync for EU accounts is in development — you'll see it in 2027 without paying extra.

Can I cancel anytime, no strings?

Always. Pro is a monthly plan you manage from a Stripe-hosted portal — one click to pause or cancel, refunded on the spot if you change your mind in the first 14 days. Founding is a one-time payment, so there's nothing to cancel.

Which currencies do you support?

Over 30 — every currency the European Central Bank publishes a rate for, plus a few extras like the Albanian Lek that we sourced separately so multi-currency families aren't left out. Adding a new currency is a one-line change; ask and we'll usually have it the same week.

Is Penni giving me financial advice?

No. Penni is an analysis tool — it surfaces patterns in your own numbers and explains the trade-offs in plain language. You stay in the driver's seat for every decision. We'll happily flag “you spent more on dining than rent this month” — we won't tell you which stock to buy.

When will I get my invite?

We're opening seats in small batches so onboarding feels personal, not transactional. Most early signups hear from us within 7–10 days. The waitlist page tells you exactly where you are in line — and referring a friend bumps you up.

What if I'm not technical?

Then you're exactly who we built this for. There's nothing to install, nothing to sync, no API keys, no spreadsheet formulas. If you've used Notes on your phone, you can use Penni — and our AI advisor explains anything you're unsure about, in your language.
