MyoAmigo Privacy Policy

Last updated: September 22, 2026

MyoAmigo ("the app", "we", "us") is a workout tracker for iPhone and Apple Watch, with a web companion and an interface for AI assistants, published by Verbari LLC. This policy says what data MyoAmigo handles, why, where it goes, and the choices you have. It is written to be specific: there is no advertising, no tracking, and no selling of your data.

The short version

• MyoAmigo works without an account. Without one, your data never leaves your device.
• With an account, your training data syncs to our own servers so it's available on your devices, on the web, and to AI assistants you connect.
• Apple Health data is off by default. You choose, category by category, whether MyoAmigo keeps a copy on your account, and you can delete that copy at any time.
• No advertising identifiers, no third-party analytics or tracking SDKs, no data brokers.
• Health data is never used for advertising or marketing and is never sold.
• Your live location is processed on your device only and is never uploaded.
• You can delete your account and everything on our servers at any time, from inside the app.

Data we handle

Account

If you create an account, you sign in with Sign in with Apple, a passkey, or an email address and password. We store the email address associated with your account, an optional display name, your timezone (so dates and "today" line up across devices and assistants), and the credentials needed to keep you signed in. Passwords are stored only as salted hashes. Sign in with Apple may give us a private relay address instead of your real one; that is fine with us.

Training data

When you're signed in, the following sync to our servers: strength workouts (exercises, sets, weights, reps, rest, per-set effort ratings, notes, and, when your Apple Watch records them, per-set average and peak heart rate), routines and weekly plans, cardio activities (type, distance, duration, notes), custom exercises, gyms you save, and your app settings (units, accent color, the biological sex used for strength standards, training focus, avoided exercises, and similar preferences). Assistants you connect can also add profile notes such as a target date or a note about constraints; those sync too.

Body data

Bodyweight, body-fat percentage, lean mass, and tape measurements that you log in the app, that an assistant logs for you, or that MyoAmigo imports from Apple Health, are stored as body metrics and sync with your account. Imported readings are tagged as coming from Apple Health and deduplicated against the ones you typed yourself.

Apple Health: what MyoAmigo reads by default

With your permission, MyoAmigo reads from Apple Health:

• Bodyweight, body fat, lean mass, waist, and height, imported into your body metrics as described above.
• Biological sex, read once to calibrate strength standards and stored as a male/female preference that syncs with your other settings.
• Heart rate during a Watch-tracked workout, summarized per set (average and peak). The summaries sync with your sets; the raw sample stream stays in Apple Health.
• Cardio workouts (runs, rides, swims, and similar), imported so they appear alongside your strength training. The summarized activity syncs; raw Health metadata does not.

MyoAmigo also writes your completed strength workouts to Apple Health (Watch sessions record natively; phone-only sessions are written on completion) so they count toward your Activity rings and appear in other apps. MyoAmigo never writes your bodyweight or any other body data into Apple Health.

Apple Health: the optional copy on your account (Data Sync Center)

Health data lives only on your iPhone and Apple Watch. AI assistants that run outside your phone can only see it if you let MyoAmigo keep a copy on your account. That copy is off by default and controlled in Settings → Data Sync Center, one switch per category:

• Body composition: weight, lean mass, body fat, BMI, waist, height.
• Recovery: resting heart rate, walking heart rate, heart rate variability, VO₂ max, post-workout heart rate recovery, and sleeping wrist temperature.
• Sleep: one summary per night (time in bed, time asleep, sleep stages, awakenings) computed on your phone. The individual sleep segments are never copied.
• Daily activity: daily totals only, such as steps, active and resting energy, exercise minutes, flights climbed, and a daily heart-rate range (average, low, high), plus daily respiratory rate and blood-oxygen averages. Your heart-rate stream is never copied.
• Nutrition: daily totals of calories, protein, carbohydrates, fat, fiber, water, and alcoholic drinks, as recorded in Apple Health by whatever app you log food in.

What we do with that copy, and what we don't:

• Turning on a category asks Apple Health for permission once, for all categories together. Both your switch and Apple's permission are needed; either one alone syncs nothing.
• The copy is stored in a separate database from your training data, on the same infrastructure, and is used only to power features you ask for, such as showing it to assistants you connect through the tools described below. If we add features that use it in new ways, we'll update this policy and tell you in the app first.
• We retain identifiers needed to deduplicate individual readings, their units, and their source. Sleep summaries keep the source and session times; we do not store the underlying segment identifiers.
• Initial import covers up to three years. Body readings, daily recovery/activity/nutrition summaries, and sleep session summaries remain until you delete them. Individual recovery readings are retained for 12 months, then condensed into daily history. We preserve detail if its summary still needs repair.
• Body composition history is free. Free access to other Health categories covers the current day and previous 29 days; MyoAmigo Pro unlocks their retained history. Losing Pro does not delete history or stop your selected categories from syncing. You can export all retained Health data free in Data Sync Center, including history outside the free viewing window.
• We never copy your raw heart-rate stream, your workouts (those import separately), reproductive or cycle-tracking data, medications, clinical records, ECG, blood glucose, or blood pressure.
• Turning a category off stops syncing it. The Data Sync Center also lets you delete our copy of one category or all of them, or wipe it and rebuild it from Apple Health, at any time. Deleting your account deletes the copy too. Nothing you do in MyoAmigo changes Apple Health itself.
• Health data is never used for advertising, marketing, or data mining, is never sold, and is never shared with data brokers or third parties other than the service providers and assistants described in this policy, as required by Apple's guidelines.

Location and gyms

MyoAmigo uses location only for the optional gym features, and only with your permission:

• Gyms you save. A saved gym's name, address, and map coordinates sync with your account like any other training data. If you store your membership check-in code so the app can show it at the front desk, that code syncs with the gym.
• Arrival detection. If you enable gym-arrival notifications, geofence monitoring runs on your device using Apple's location services. Your live location is never sent to our servers, and we keep no record of your movements. A workout can be tagged with the saved gym it happened at, which is a reference to that gym, not a coordinate trail.
• Don't save any gyms, and the app never touches location at all.

Progress photos

Progress photos you take in MyoAmigo are stored only on your phone. They are never uploaded, never synced, and never included in any backup we hold. Deleting the app deletes them.

MyoAmigo Pro

Purchases are made through Apple. We never see your payment details. To keep your Pro features working across devices and the web, we store the subscription status Apple reports to us and Apple's transaction identifiers for your purchase. Promo and redemption codes you enter are recorded against your account.

Usage analytics (first-party, counts only)

To understand which features are used, the app can send us daily counts of named events (for example, how many times "workout finished" happened on a given day). The counts carry no content, no free text, no device identifiers, and no location. This uses no third-party SDK and no advertising identifier, and you can turn it off in the app's settings. It never runs when you're signed out.

Feedback you send

When you use an in-app or assistant feedback feature, the message you write, the category you choose, an optional contact email, and basic app-version context are stored with our support records and emailed to our support inbox so we can respond. Feedback belongs to the signed-in account that sent it: its history and status are visible only to that account, not to other users. It is deleted with that account. Feedback is used only to answer you and improve the product.

For a feature request, you may separately opt in to one email if that specific request ships. We send it only after we verify the request-to-release mapping, and only to the verified email address on the associated account. This is not a marketing subscription. We do not send a release email for requests without that opt-in, to an optional contact address, or to an unverified account email.

Operational and security logs

When diagnostics sharing is on through the usage analytics setting in Data & Privacy, we collect crash and performance reports from Apple's MetricKit to keep MyoAmigo working reliably. These reports are linked to your account, kept for 90 days, and deleted when you delete your account. They contain unsymbolicated call stacks, app and device versions, reporting windows, and performance summary numbers; they do not include your workout content or free-text messages.

Our servers keep short-lived operational logs (request metadata, errors, and security events such as authentication failures and rate-limit hits) to keep the service running and detect abuse. They are retained for a period measured in days and then deleted automatically. They are not used for advertising or profiling.

What we do not collect

• No advertising identifiers (IDFA) and no use of App Tracking Transparency.
• No third-party analytics, crash-reporting, or marketing SDKs.
• No live location on our servers, and no history of where you've been.
• No contacts, no microphone, and no photos other than the progress photos you take in the app, which stay on your phone.
• No payment card details.

AI assistants

MyoAmigo's servers include an authenticated interface (MCP) that lets an AI assistant access your own data on your behalf when you connect it and ask it to. Connecting an assistant uses an OAuth authorization flow, or an API key you create yourself: you sign in and explicitly approve the connection before the assistant gets any access, and every request it makes is authenticated against your account. You can revoke a connection at any time (disconnect it in the assistant, or revoke access and rotate your API key from your MyoAmigo account), after which its credentials stop working.

When you use MyoAmigo through an assistant, the data the tools return is transmitted to the AI service you connected (for example OpenAI for ChatGPT, or Anthropic for Claude) so it can show and discuss it with you. That includes your workouts, routines, plans, body metrics, analytics, and, if you have turned on categories in the Data Sync Center, the Apple Health copy described above. This happens only for accounts you connected, and only when you or your assistant makes a request. Once data leaves our system it is handled by that provider under its own terms, and we can't control how it is used, stored, or retained. Connect only assistants you trust, share only what you're comfortable sharing, and review each provider's own privacy terms.

We do not use your data to train AI models, and we do not sell it or share it with third parties beyond what this policy describes.

Service providers

We use a small number of providers to run MyoAmigo, each processing data only on our instructions:

• Cloudflare (United States) hosts our servers and databases.
• Amazon Web Services (Simple Email Service, United States) delivers transactional email such as verification, password reset, and support replies.
• Apple provides sign-in, purchases, HealthKit, and app distribution under Apple's own terms.

Your synced data is stored in the United States. If you use MyoAmigo from elsewhere, you're transferring your data to the United States for processing as described here.

How your data is stored and secured

All communication between the app, the web companion, assistants, and our servers is encrypted in transit. Data at rest is stored on encrypted cloud infrastructure under our control. Your session credentials are kept in the iOS Keychain on your device, access tokens are short-lived and expire automatically, and API keys you create are stored only as hashes.

Retention and your choices

• Sync is optional. Without an account, your data never leaves your device.
• Retention. Synced data is kept for as long as your account exists so it stays available across your devices. Records you delete are removed from active use immediately.
• Apple Health copy. Manage, pause, delete, or rebuild it any time in Settings → Data Sync Center. Review or revoke Apple's permission in the iOS Settings app under Privacy & Security → Health.
• Analytics. Turn usage counts off in the app's settings.
• Location. Revoke location access in iOS Settings; arrival features simply stop.
• Account deletion. Open Settings → Account → Delete Account in the app. Deletion is immediate and permanent and removes your training data, your Apple Health copy, your subscription record, your feedback history, and any assistant connections from our servers. Signing out clears your credentials from the device without deleting anything.
• Export. You can export your workouts and cardio as CSV from the app at any time, and assistants you connect can read everything through the same interface.

Your rights

Depending on where you live, you may have rights to access, correct, export, restrict, or delete your personal data, and to withdraw consent. The controls above cover most of this directly; for anything else, email us and we'll respond within 30 days. For people in the European Economic Area and the United Kingdom: we process account and training data to provide the service you signed up for, usage counts and security logs on the basis of our legitimate interest in running and improving it, and Apple Health data, which is health data, only with your explicit consent given through the Data Sync Center switches, which you can withdraw at any time. Verbari LLC is the controller.

Website

This website sets no analytics or advertising cookies. During pre-launch we ran an email waitlist here; if you joined it, we stored the address you submitted, when, and from which page, protected by Cloudflare Turnstile (a bot check without cookies or tracking) and a briefly kept salted hash of your network address for rate limiting. Waitlist emails were used only for launch news and you can ask us to remove yours at any time.

Not a medical service

MyoAmigo is a fitness tracking tool, not a medical service. It does not provide medical advice, diagnosis, or treatment, and the data it handles, including heart-rate summaries, sleep, and body metrics, is processed for training insight, not health care. MyoAmigo is not a HIPAA covered entity. See our Terms of Service for the full health disclaimer.

Children

MyoAmigo is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has created an account, contact us and we will delete it.

Changes to this policy

We may update this policy as the app evolves. Material changes will be reflected by the "Last updated" date above, and changes that expand what we collect will be announced in the app before they take effect.
