Privacy Policy

Effective date: 4 September 2026.

Stacked is a strength-training app for iPhone and Apple Watch. This policy is short because there is not much to say: Stacked does not collect your data.

— What we collect

Nothing. Stacked has no accounts, no sign-up, no analytics, no tracking, no advertising and no third-party services. We never see your name, your email address, your workouts, or anything else about you. This website sets no cookies and runs no analytics either.

— Where your data lives

Everything the app records — your exercises, ranks, workout history, badges, equipment, places and settings — is stored locally on your device, in the app's own storage. It is never transmitted anywhere. The app works fully offline and makes no network requests to us or to anyone else.

— Location

Stacked can optionally use your location for two things, both entirely on your device:

Your location is processed on the device and never transmitted anywhere. When you log a run, the route is saved in two places, both under your control: in your local history on this device, and — if you allow it — to Apple Health, which stores the workout and its route alongside the rest of your fitness data. Deleting a run in Stacked deletes its saved route; Health data is managed in the Health app. Location permission is optional: decline it and everything except place auto-select and outdoor run mapping works exactly the same.

— Apple Health

With your permission, Stacked writes finished workouts to Apple Health — the session, its heart rate and, for outdoor runs, its route — so your training appears in Fitness alongside everything else you do. It reads your date of birth, if you allow it, purely to estimate a maximum heart rate for the training zones. Health data stays on your device and in Apple's own encrypted storage; Stacked never sends it anywhere. Permission is optional and revocable at any time in the Health app, and the app works without it.

— Notifications

This version of Stacked does not use notifications and does not ask for notification permission. If a future version adds them they will be local notifications — scheduled and shown entirely on your device by the operating system, with nothing leaving your phone — and this policy will be updated before that version ships.

— Deleting your data

Because all data is on your device, you are always in control of it:

There is nothing for us to delete on any server, because nothing was ever sent to one.

— Children

Stacked collects no data from anyone, including children.

— Changes to this policy

If a future version of Stacked ever changes how data is handled — for example, optional cloud sync — we will update this policy and change the effective date before that version ships.

Stacked iPhone & Apple Watch
— Strength training, dealt daily

Your deck is your progress bar.

Every workout is a dealt hand — one card per exercise. Each card's rank is your current level in that movement, so the deck itself shows what you can do. No abstract points. No streaks to protect.

Coming to the App Store $9.99 · one purchase · every deck included
Stacked's home screen: a weekly plan called Full House, today's session named Five of a Kind, a week strip with three days filled, and suit progress at levels four and five.

— 01 · The hand

One card. One lift. One number that moves.

Swipe through the hand top to bottom. Finish a card's prescription cleanly three times and it ranks up — with the next challenge shown before you rack the weight.

— Plate math

It tells you which plates to load.

The prescription is floored to a weight your bar can actually hold, never rounded up past it — and the card draws the plates, heaviest inboard, so you load it without arithmetic.

Adjust today's weight with the stepper and the diagram follows. The adjustment is a witness, not a promotion: it changes today, never your ladder.

A back squat card: ninety pounds for five reps, a minus-plus stepper, five set segments, and a barbell diagram loaded with two ten-pound plates and a two-and-a-half.
— Ranks you can lose

The deck shows what you are, not what you once were.

Leave it idle too long and cards slip back — gently, with a grace period and a floor, and a comeback rule that makes rebuilding faster than the first climb.

Weekly challenge hands raise the stakes: real poker hands, from a humble Pair to a Royal Flush, each with a badge on the line.

A stats screen: streak, thirty-nine sessions, overall level four, plan adherence for this week and last, and a badge case with four of nine earned.
— 02 · The week

Lifting and cardio, on the days you actually train.

Build a week once and the Hand tab deals whatever is scheduled. Go off-plan and it's a side bet — the plan resumes the moment you log it.

— Knows your gear

Tell it what's at home and what's at the gym.

Pin each place on the map and Stacked picks the right setup the moment you walk in — plates, bars, bells, machines, the lot.

It refuses to lie. Bring up a barbell session somewhere with no barbell and it says so, instead of quietly inventing a number and dropping your warm-up.

— 03 · The run

Runs, drawn in your heart rate.

Cool blue where you were easy, amber at threshold, red where you buried yourself. Runs are kept — so the same loop a month later shows you the colour change.

— Pocket it

Big timers, real pace, haptics at every boundary.

Outdoor runs get a session of their own: a live map, a countdown for the segment you're in, and distance and pace as they happen.

A haptic marks every work and recovery boundary, so the phone can stay in your pocket — and recording continues with the screen locked.

A live run session: a map of Central Park with the route traced in orange, a two-minute-twenty-six countdown for the warm-up segment, and distance, pace and elapsed time below it.
— 04 · The wrist

A companion, not a remote control.

Start a hand on the phone and the watch already knows the movement, the weight and the set you're on. Tap the wrist to log a set. Feel the rest timer count down. Check your heart rate without breaking position.

The Apple Watch app mid-lift: Five of a Kind, card two of six, back squat, five by five at ninety pounds, with five set segments and the next lift named below.
— Mid-lift
The Apple Watch app resting between sets: a large countdown reading two minutes fifty-four.
— Between sets

Runs get the same treatment, with boundary haptics where you can actually feel them. Every session writes to Apple Health as a real workout — route and heart rate included — so it lands in Fitness alongside everything else you do.

— 05 · What's in the box

Real programs, not filler.

Proven lifting templates — 5×5 linear progression, AMRAP-driven progression, wave periodization with training-max testing — and structured cardio for running, rowing and cycling, each at beginner, intermediate and advanced tiers. A kettlebell library with its own rank ladders, and a deck builder if you'd rather author your own.

Every deck is included. There is nothing to unlock, no subscription, and no second purchase.

— 06 · Yours alone

No account. No ads. No tracking.

Stacked makes no network requests and works completely offline. Your training — your location included — never leaves your phone, except to Apple Health if you ask for it.
