trAIner

Common questions

How do I add a workout?

In trAIner, tap + (Add Workout) › Get Workout Prompt and copy the prompt into an AI chat such as ChatGPT or Claude. Describe the workout you want, then share the reply to trAIner, or copy it and tap + › Paste. trAIner creates a structured workout and opens it so you can review it before sending to the Apple Watch. If you have your own OpenAI or Anthropic API key, you can use it to plan workouts directly in the app.

Why isn’t my workout on Apple Watch?

trAIner asks Apple to schedule the workout. After scheduling, the workout is sent to the Apple Watch. trAIner can show that a workout is scheduled, but it can’t confirm that your Watch has received it due to limitations in iOS. Check that:

• your Apple Watch is paired, nearby and running watchOS 11 or later;
• scheduling is allowed for trAIner (if it’s off, trAIner offers Open Settings);
• Apple’s schedule isn’t full (trAIner can remove its own past workouts to make room).

Why doesn’t History show my workouts?

History reads completed workouts from Apple Health, and only with your permission. If workouts are missing, open iPhone Settings › Privacy & Security › Health › trAIner and allow it to read workouts.

Do I need an AI subscription?

No. You can design workouts in whatever AI chat app you already use and share the result with trAIner. For planning and analysis inside the app, add your own Anthropic or OpenAI API key in trAIner’s Settings › AI Provider. Your provider bills that key, so create a dedicated key with a spend limit in your provider’s console. On iPhones with Apple Intelligence and iOS 27, you can also create workouts on the iPhone at no cost.

What’s sent to the AI provider, and how do I stop it?

Nothing is sent until you allow a provider. Before you send a plan, analysis or follow-up, What’s Sent shows the text that goes. To stop, choose Stop Sharing in trAIner’s Settings › AI Provider, or remove your key. The privacy policy lists everything a request can include.

How do I delete my data?

• A workout: swipe left on it in Workouts and choose Delete.
• AI conversations and Coach Notes: delete one from its workout, or all of them in Settings › AI Provider › Delete All Conversations.
• About Me notes: delete them in Settings › About Me.
• Everything: deleting the app removes its data from your iPhone.

Pathogenuity LLC never receives your data, so there’s nothing for us to delete. Requests you sent to an AI provider are covered by that provider’s own policy.

Is trAIner medical advice?

No. trAIner helps you plan and review exercise. Check with a doctor before starting a new training program or making medical decisions. If you have symptoms such as chest pain, stop and seek medical help.

Which devices does trAIner support?

iPhone 12 mini and later, running iOS 18 or later, including both displays of iPhone Duo. Scheduled workouts run on Apple Watch with watchOS 11 or later. There’s no iPad version.

trAIner is an iPhone and Apple Watch app. It turns workouts you describe into Apple Watch workouts, and can help you look back on completed ones. This policy explains what trAIner does with your information.

The short version

• No developer servers. trAIner has no account, no server, no analytics, no advertising and no tracking. Pathogenuity LLC does not receive your data.
• Your data stays on your devices unless you choose to send it somewhere.
• The optional AI coach is the exception. If you turn it on and add your own Anthropic or OpenAI API key, trAIner sends what you ask about to the provider you chose. It sends nothing until you allow that provider, and you can review what will be sent before each request.
• Apple Health data is read-only. trAIner never writes to Apple Health, never sells Health data, and never uses it for advertising or marketing.

What trAIner stores on your iPhone

• Your workout library: workouts you import or create, kept in the app’s own storage.
• The next scheduled workout: a short workout summary shared with trAIner, its Share extension and your Apple Watch.

• Coach data, if you use the coach:

  • your About Me notes, such as an injury or a goal;
  • your workout check-ins: how hard a workout felt, any pain and where, and a note;
  • your Coach Notes: short dated notes from each analysis, or ones you write or paste yourself;
  • your coach conversations, including exactly what was sent and what came back.

  These are stored on the iPhone with iOS Data Protection. They are not in iCloud sync or the shared App Group. They are excluded from iPhone backups, so they don’t move to a new iPhone, and you would need to re-enter them there.

• API keys: stored only in the iPhone’s Keychain on the device running trAIner and are not synced between devices. iOS keeps Keychain items after an app is deleted, so there is a Remove Key option within trAIner that can be used to completely delete an API key.

Apple Health

With your permission, trAIner reads but does not write Apple Health data. It reads:

• Workout results and analyses: completed workouts and their measurements, such as heart rate, pace, distance, power and cadence. It also reads the workout’s GPS route, but only if you choose to include it.
• Not read: trAIner does not read Reproductive Health data, such as menstrual, pregnancy, contraceptive or sexual activity records, even if you choose Search All Health Data.
• For coaching: recent sleep, resting heart rate, heart rate variability, respiratory rate and wrist temperature, plus summaries of your training history. It reads these only when Use Health Context is on.

Health data is used only to give you your workout results and coaching. It is never used for advertising, marketing or data mining, and it is never sold. It leaves your iPhone only when you share it yourself, or when you ask the AI coach for something that uses it, as described below.

User-controlled data sharing

• Share and copy. When you share a workout export or copy a prompt, it goes where you send it, such as Files, Mail or your own ChatGPT or Claude app. That destination’s privacy policy then applies.
• Apple Watch scheduling. Workouts you schedule are handed to Apple’s WorkoutKit, which delivers them to your Apple Watch.

The optional AI coach

The in-app virtual coach is off until it is turned on, an AI provider is selected, and an API key for that provider is added.

What is sent, and when. trAIner contacts Anthropic or OpenAI only after you:

1. turn on the AI coach and add your own API key;
2. allow that provider, once (you can withdraw this with Stop Sharing or by removing the key);
3. tap Send, Analyze or ask a follow-up.

Saving a key sends only the key to that provider, to check it.

What a request can include:

• Always: your request, your About Me notes, your recent check-ins, and Coach Notes from earlier workouts, with short takeaways for workouts analyzed before Coach Notes. Every request also includes today’s date and your time zone. A follow-up includes the conversation so far. For analysis, the workout’s record from Apple Health: its times, plan, laps, measurements and the model of the device that recorded it.
• Only when Use Health Context is on: sleep, resting heart rate, heart rate variability, respiratory rate, wrist temperature and past workouts.
• Only when you turn on Include Route: the workout’s GPS route.
• Only when you turn on Search All Health Data: every Health measurement linked to the workout.

What’s Sent shows the content before you send it. If an analysis’s Coach Note is longer than 100 words, trAIner automatically sends one more request to shorten it. It’s billed like any other request.

How the provider handles it. Your request goes from your iPhone directly to the provider, under your own account and that provider’s API terms and privacy policy:

• Anthropic: https://www.anthropic.com/legal/privacy
• OpenAI: https://openai.com/policies/privacy-policy

trAIner asks OpenAI not to store responses (store: false). Providers may still keep API data for a limited time under their own policies, for example for abuse monitoring. Charges for these requests are billed by the provider to your account. trAIner shows an estimate before you send.

On-device drafting. On iPhones with Apple Intelligence (iOS 27 or later), you can choose Plan with Apple Intelligence. It drafts workouts on the iPhone itself. Nothing is sent off the device, and no Health data is used.

Deleting your data

• Coach conversations: delete one with Delete Conversation, or all of them in Settings › AI Provider › Delete All Conversations, which also deletes your Coach Notes.
• Coach Notes: delete one with Delete Coach Notes on its workout. You can also paste or write your own there.
• Notes: delete them in Settings › About Me.
• Check-ins: delete one with Delete Check-In on its workout.
• API keys: delete them with Remove Key in Settings › AI Provider. This also withdraws that provider’s permission.
• Apple Health access: change it in the iPhone’s Settings › Health › Data Access & Devices.
• Everything else: deleting trAIner removes everything it stored on the iPhone except Keychain API keys (see above). Coach data is not in your backups. Copies of anything else follow your backup settings.

Data already sent to a provider is governed by that provider’s policy. Pathogenuity LLC never receives it, so it cannot delete it for you.

Children

trAIner is not intended for use by children under 13.

Changes

If this policy changes, the updated version will be published here with a new effective date. A material change to what trAIner sends, or to whom, will also be described in the app before it takes effect.
