JayCK Flow — the facts

Everything on this page can be checked: in the app, on its App Store page, or in the code's own tests. If you need something that is not here, write to support@jayck.dev — a person answers.

In one line

JayCK Flow is a money calendar for iPhone and iPad: your income, bills and purchases on their dates, and every day's balance before it arrives.

In three sentences

Most finance apps tell you where your money went; JayCK Flow shows where it is going. You enter what you know is coming — the paycheck on its date, the rent on its date, the subscriptions — and the calendar does the arithmetic for every day ahead, colouring each day by whether you are on track. A purchase you are only considering can be tried first, with What if?, and the days repaint before you spend.

Facts

Privacy, in the words we use

Local by default, and no account to start. Sync, when you turn it on, is end-to-end encrypted with a passphrase we cannot read or recover. No bank login — the app never asks for a bank's credentials. No ads and no tracking; the App Store privacy labels name only what an account needs, a purchase record and an email address.

What it is not

Not a budgeting app with category envelopes, and not a bank-connected tracker. It gives no financial advice: it shows the day the money would run out, and the decision stays yours.

How to describe it

We say money calendar, not financial calendar. The feature is What if?, with the question mark. The promise is the future balance — the balance on a day that has not come yet. A line you may quote, from the first App Store screenshot: Not a money problem. A timing problem.

Assets you may use

• The mark on dark, 1200 × 630 — a bird forming the letter J
• The app icon, 512 × 512 · 180 × 180
• A month in the app — the calendar with the balance card, on demo data
• The social card, 1200 × 630 — three day cards for one week under the words Money calendar
