Press Add subscription (the + in the tab bar on phones). Search a catalog of 250+ services — each with its real logo and a typical price in your currency — or type any name to add your own.

• Set the price you actually pay and how often: weekly, monthly, quarterly or yearly.
• Add the next charge date if you know it; it powers the calendar and reminders. “One month from today” fills it in for you.
• On a free trial? Switch it on and set the day it ends — the app treats that day as the first charge.
• The card at the top of the form redraws as you type, so you see it before you save.

Home shows your subscriptions as a stack of cards, the most expensive per year at the front. Each card carries the price, how often it bills, its next charge (“valid thru”) and what it costs a year.

Open the front card (when the deck has focus)

• Drag up or down, or scroll, to rotate. Tap a card behind to bring it forward.
• Hover a card behind (or press and hold on a phone) to lift it out and read it.
• Fling the front card sideways to cut it — with an Undo, in case.
• The stack icon beside the deck folds it into a neat pile, or fans it back out.

Prefer a picture of the weight? Switch the home view to Scale (top right, or in You). Each subscription is a weight on the pan, sized by what it costs a year; the dial reads your monthly total. Drag a weight off the pan to cut it and watch the needle swing back. How the sizes and the dial are worked out is in How the numbers work.

Tap any card to open it. You'll see its card, three numbers and when it next charges:

• Keep — worth it, kept on purpose. Maybe — revisit before it renews. Cut — out of the jar; its yearly cost moves to your savings.
• Cutting here doesn't cancel anything with the provider. Where we know it, there's a link to the service's own account page so you can cancel there.
• Changed your mind? Open a cut card and choose “Put it back in the jar”.
• Edit details to fix the price, cycle, dates or shelf; Remove deletes it for good.

The Upcoming screen shows the next charge as a card with a countdown, a four-week calendar with each charge on its day, and every subscription in date order: this week, later, and those with no date yet. A charge ringed in red is a free trial turning paid.

In You → Reminders, “Add reminders to my calendar” downloads a calendar file your own calendar app imports. Nothing is sent anywhere; the events live in your calendar, and each one links straight back to that subscription.

• Renewals: two days before, repeating every billing cycle.
• Yearly plans: also seven days before — big charges deserve more notice.
• Free trials: the day before the trial turns paid.
• Optional monthly Weigh-In: one day a month (1st–28th) to review everything.
• Cut subscriptions get no reminders. Re-download after big changes to refresh them.

Savings totals what your cuts free up in a year, a month and a day, shows the before-and-after, and lists every card you've cut. Share your diet makes an image of your cut cards. By default it shares proportions only (“My jar is 40% lighter”) — the amount appears only if you switch it on.

The command palette searches screens, actions and every subscription. Type any words in any order — “net oct” finds Netflix renewing in October.

Everything lives in this browser, on this device: no account, no server copy, no bank login, no trackers. That also means clearing your browser data clears your jar — so back it up.

• You → Your data: Back up saves a file you keep; Restore loads it on any device or browser.
• Installing the app to your home screen gives it sturdier storage (Safari can clear website data for sites you haven't used in a week).
• Currency only changes the label on amounts; it never converts them.

Nothing is a black box. Here is every rule the app uses, drawn out with an example.
