Cue CardioPrivacy policy
The short version: Cue Cardio doesn’t collect, store or share any personal data. There are no accounts, ads or trackers. Your workouts, heart rate, settings and paired sensors stay on your iPhone. The app does send a few anonymous usage counts, like which workouts get started and finished, so we know what to make more of. They can’t be traced back to you, and you can turn them off in Settings.
Who we are
Cue Cardio is an iPhone app and website operated by Luke Chambers (“we”, “us”). Questions about this policy go to support@cuecardio.com.
This policy covers the Cue Cardio iOS app and the website at cuecardio.com. Our free workout videos are hosted on YouTube, and YouTube’s own privacy policy applies when you watch them there.
What stays on your phone
Everything below is saved only on your device, inside the app’s own storage. We have no servers that receive it, and the app doesn’t send it anywhere.
| Data | What it’s for | Where it lives |
|---|---|---|
| Workout history: date and time, workout name, time active, segments completed and, when sensors are connected, cadence, power, heart rate (average and max) and the name of the bike or strap used | Showing your history, workout complete stats and which workouts you’ve done | On your device only |
| Settings: audio, cue volume, haptics, voice cues, resistance scaling, machines, favorites and your choice about sharing anonymous usage | Remembering your preferences | On your device only |
| Paired sensors: the Bluetooth identifier and name of the bike and heart rate strap you paired | Reconnecting to the same bike and strap next time | On your device only |
Deleting the app deletes all of it. If you back up your iPhone to iCloud or a computer, iOS may include this app data in your backup. Those backups are controlled by you and by Apple, not by us.
Anonymous usage counts
To learn which workouts people use and whether Cue Cardio Plus is worth it, the app sends a few anonymous counts to TelemetryDeck, a privacy-focused analytics service based in Germany. It’s the only third-party code in the app that sends anything. The counts are:
- when the app is opened, and for how long it’s used
- which workout you open or start, its machine, type and difficulty, whether it’s free or Plus, whether a bike was connected, whether you finished and how far you got
- when the Plus screen appears, and when a free trial or plan starts or is restored
- whether you’re on the free plan, a trial or a subscription
- your app version, iOS version, device model and language
These counts never include your name, email address, Apple ID, location, heart rate, cadence, power or workout history. Before anything is sent, the device identifier is replaced with a one-way hash, so the counts can’t be traced back to you or linked across apps. We use them only to improve Cue Cardio, never for advertising, and we don’t sell them. TelemetryDeck’s own privacy policy is at telemetrydeck.com/privacy.
Sharing is on by default. To stop it, turn off Settings > Share anonymous usage in the app. Nothing more is sent after that.
Bluetooth
With your permission, Cue Cardio uses Bluetooth to read cadence and power from your indoor bike and heart rate (and battery level, if the strap reports it) from a chest strap or armband. Readings go straight from the sensor to the app on your phone and aren’t included in the anonymous counts. Bluetooth can keep working while your screen is locked or the workout is in Picture in Picture, so your workout keeps going. You can turn Bluetooth access off at any time in iOS Settings, and every cue still works without a sensor.
Audio, voice cues, Picture in Picture and Live Activities
Cue sounds play on your device and mix with, or briefly lower, other audio. Optional voice cues use the speech voices built into iOS. The Picture in Picture window, Lock Screen Live Activity and Dynamic Island are drawn on your device. None of these features send data to us. The app doesn’t use your microphone, camera, location, contacts or photos.
Apple Health
The current version of Cue Cardio doesn’t read from or write to Apple Health. If we add that, we’ll update this policy first, and the app will ask for your permission before it reads or writes anything.
Purchases
Cue Cardio Plus is a subscription sold through Apple’s App Store. Apple handles payment, and we never see your name, email address or payment details. The app checks your subscription status with Apple’s StoreKit on your device. When a trial or purchase goes through, the anonymous counts above note that it happened, without any personal or payment details. Apple gives developers aggregated sales and subscription reports, as it does for every app. Apple’s privacy policy covers those purchases.
No tracking, no ads
Cue Cardio has no advertising and no tracking. Apart from the anonymous counts above, there’s no analytics, crash reporting or other third-party code that collects data. We don’t track you across other apps or websites, and we don’t sell or share personal information. The app doesn’t ask for permission to track, because it doesn’t.
If you’ve chosen to share diagnostics with app developers in iOS Settings, Apple may give us anonymous crash reports and usage statistics. You control that setting in iOS, under Privacy and Security, then Analytics and Improvements.
This website
cuecardio.com is a static site. It doesn’t use cookies, analytics or trackers, and it has no forms. Like any website, our hosting provider may process standard technical information, such as your IP address and browser type, in server logs to deliver the site and keep it secure. We don’t use those logs to identify you.
When you email us
If you write to support@cuecardio.com, we receive your email address and whatever you include in your message. We use it only to reply and help you, keep it only as long as needed for that, and don’t add you to any mailing list. Our email provider stores those messages for us.
Deleting your data
Because your data is on your device, you’re in control. Deleting the app deletes your workout history, settings and paired sensors. The anonymous counts aren’t linked to you, so there’s nothing in them we could find and delete for one person. To stop sending them, turn off Share anonymous usage. To stop a subscription, cancel it in your iPhone’s Settings under your Apple ID, then Subscriptions. To have us delete a support email, just ask.
Your rights
Depending on where you live, laws such as the GDPR or the California Consumer Privacy Act may give you rights to access, correct or delete personal data and to opt out of its sale or sharing. We don’t sell or share personal data, and apart from support emails we don’t hold any about you. To make a request, email support@cuecardio.com.
Children
Cue Cardio doesn’t collect personal data from anyone, including children under 13. The anonymous counts work the same for everyone and contain nothing that identifies a person.
Changes to this policy
If our practices change, for example if we add Apple Health, we’ll update this page and the date above before the change ships, and the policy inside the app will match.
