Settings, account, privacy and subscriptions

Your goal, session length, membership, account, data and privacy, and where to get help.

Opening Settings

Tap on the dashboard to open Settings. It is a short list: your coach and what you’re aiming at, how long a typical session is, your membership, and the doors under Everything else: Keyboard & sound, You & account, Support & legal and a measurement page.

Each door’s second line shows what is behind it before you tap, such as your keyboard’s size or your goal.

Your coach

Your coach shows who talks to you in KeyFu: one coach, named KeyFu — the coach itself is not something you pick.

What you’re aiming at is your goal, and it lives with the coach because it is what the coach plans against. Tap it to change it (see Your goal).

Replay guided moments brings back the short introduction cards KeyFu shows the first time you meet something new. Tap it and each card appears again the next time you meet that thing — not all at once.

Coaching and limits

The coach’s replies are written by AI models from other companies, which costs money, so the coach has limits; the rest of KeyFu does not. On the free plan the Your coach row shows how many coach messages you’ve used this week, and that it resets on Monday.

Tap it for Coaching & limits: what gets counted, what is never limited, and what happens when you reach a limit. Practicing, the exercise library and your progress are never limited, and a practice session never waits for the network.

When a coach limit is reached

When the free week’s coach messages are used, the chat pauses until Monday; the thread stays readable. With Pro, when this month’s coach messages are used, the chat pauses until the first of the next month. Your session cards and the weekly line are written by the app itself, so nothing there waits on a limit.

You never lose anything you have played.

How long a session is

≈ A typical session lets you pick how long you usually practice in one sitting. Tap one of the lengths; the highlighted one is current.

Today’s plan on the dashboard is built to fit the length you pick, so choose what you really have — shorter bursts are fine. You can change it whenever your days change.

Free plan and Pro

Membership says which plan you’re on: Free plan, or Pro marked ACTIVE. On the free plan, tap the row to see KeyFu Pro.

Membership also holds Restore Purchases and Have a code? Redeem it here. With Pro, it also shows Manage Subscription: it opens the App Store’s own page for your subscription, where you can change your plan or cancel, without leaving KeyFu. What you’ve learned stays free to see.

Subscribing

The KeyFu Pro page lists the subscriptions the App Store offers, each with its price as the App Store shows it; the yearly one is picked for you. When the App Store offers a free first week on it, the button reads Start free trial; otherwise it reads Subscribe. The page also explains renewal: the subscription renews automatically until you cancel it in your App Store account settings, at least 24 hours before it renews. Apple’s own purchase sheet does the rest. closes the page without buying.

If the App Store can’t be reached, the page says so and offers Try again. Once Pro is active, the page closes by itself.

Restoring a purchase

Already subscribed on another device? Restore Purchases brings Pro back here. It is in Membership and on the KeyFu Pro page. Once Pro is active, Manage Subscription is there too, for changing or canceling the subscription.

You always get an answer: Pro restored, No subscription found on this Apple ID, a note that the subscription belongs to a different KeyFu account, or that the App Store couldn’t be reached. If the subscription is linked to another account, sign in with that one or get in touch.

Redeeming a code

Got a code for KeyFu Pro? The quickest way is the link in the email that brought it: one tap opens Apple’s redeem sheet with the code already filled in.

You can also tap Have a code? Redeem it here, on the KeyFu Pro page or in Membership. Apple’s own sheet opens; type the code there. Once it is redeemed, Pro is active.

Your goal

Your goal is what the whole app aims at, and it is free for everyone. Tap What you’re aiming at to change it.

Pick a ready-made goal, such as Chord fluency, and add your own words if you like. Then tap Save goal. Nothing you’ve built resets; only what comes next changes.

Your goal decides which skills each day’s exercises lean on, which way an exercise gets harder first, and your two-week focus. A new goal steers from your next session. On the free plan, once this week’s built session is used, from your next built one.

If your two-week focus no longer fits the new goal, the coach says so and picks a new one after your next session.

What your goal leans on

After you save, the coach works out which skills your goal leans on — such as Chord shapes, Timing, or Ear — and shows them checked. Change any, then tap That fits.

If the coach can’t work it out, for example offline, a ready-made goal’s usual skills are checked for you; for your own words, check them yourself, then tap Aim there. Not now keeps your goal: a ready-made goal leans its usual way, and your own words aim broadly until the coach can read them.

Checking Ear shows your goal on the wheel; the ear drills themselves are in Train your ear.

Saving a goal never counts against the daily limit on new plans from the coach.

Your name and careful hands

You & account starts with the name the coach calls you; type it and it’s saved.

Take it easy on my hands makes sessions lighter, with earlier breaks. Turn it on if your hands tire easily or you’re coming back after a break.

Exporting your data

Export My Data makes one file with everything KeyFu holds about you: your practice history from this device, and what KeyFu’s server keeps for your account. You can then save or send it with the usual share sheet.

The device part never needs the network. If the server can’t be reached, the file says so — export again when online to include it.

Your age range

Where the law asks apps to check a player’s age range, KeyFu asks once when you first open it, after a short screen that says why. Share my age range lets Apple share just your range. Pick from a list instead opens a short list; pick your range and tap Continue.

Your answer stays on this device. It is never sent to KeyFu’s servers, and KeyFu never asks for your birthday. Export My Data includes it, and Delete Account removes it.

To correct it, open Age in your account settings. In some places KeyFu is for adults only for now.

Signing out

Sign out forgets only who is signed in. Your practice history, settings and measurements all stay on this device, and the next screen asks you to sign in again with Apple.

When your coach session has ended

KeyFu’s server stops accepting a device’s sign-in after a while. When that happens nothing on the device changes: you keep practicing, and the coach keeps answering from what it knows on this device only — no server-written recaps, no weekly summary, and the coach limits row stays empty. Sign in again appears in You & account for as long as that is the case. Tapping it runs the usual Apple sign-in over your existing account, without signing you out first; your history, settings and measurements are not touched.

Deleting your account

Delete Account stands apart, in red, and opens a confirmation where you type DELETE before the button works. It reminds you that your practice history lives only on this device, so deleting erases it for good along with your keyboard and headphone setup, saved plans and coach chats. It can’t be undone. It also says that deleting doesn’t cancel KeyFu Pro and offers Manage Subscription. Your Apple ID itself is never touched.

KeyFu deletes the account on its server first. Only when that succeeds is everything on this device erased too — history, settings, keyboard and headphone measurements — and the app starts from the beginning. Without a connection nothing is deleted; try again once online.

Where your data lives

Your practice history is kept on this device, not on KeyFu’s server. Removing the app removes it, and it doesn’t move to another device through your account. An iPhone or iPad backup keeps it, and Export My Data gives you a copy. Syncing between your devices comes in a later update.

Headphones and keyboards are remembered on this device under a scrambled code rather than their names.

Usage data

Support & legal holds the Share usage data switch. It is off until you say yes, there or when KeyFu asks once, after your first finished session: Share usage data or No, thanks. Swiping the question away counts as no.

When it is on, KeyFu counts which screens and steps you use, roughly how long you practice, whether you changed today’s plan, and whether it held a new exercise or one from your last two sessions, with a random ID for this install. The counts go to TelemetryDeck and KeyFu’s own server. Your name, your Apple account, your coach messages and what you play note by note are never sent. Turning it off deletes the install ID from this device.

AI for coach replies

Support & legal holds the Use AI for coach replies switch. It is your answer to the question KeyFu asks before the coach first uses AI.

On, your messages to the coach, your practice goals and a summary of your practice go to the AI providers Anthropic and OpenAI to write the coach’s replies. They don’t train their models on it, but keep it for a limited time to detect misuse; the privacy policy has the details. Off, nothing goes to them: the coach keeps its short built-in lines, and the chat can’t answer.

Help, privacy and credits

Help & contact opens an email to a human, already filled in with your app version and device, so a problem can be traced. keyfu.app has news and updates.

Privacy policy and Terms of use & imprint open on the web. Type, sound & licenses credits the typefaces and the piano recordings. Settings also shows the app’s version, handy when you write in.

Practice time, measured

Practice time is a measurement page: your recent sittings, how long you actually played compared with what was planned, and how your headphones and keyboard were recognized.

It is the one place in KeyFu that shows measured figures. You don’t need it to practice; it is there when you want to see the numbers, or when support asks for them.
