CycleTron Privacy Policy
This policy explains what the CycleTron app for iPhone and Apple Watch does with your information. CycleTron keeps everything on your devices. It has no account and no server, and nothing leaves your devices unless you share it yourself.
In short
- There is no account and no sign-in. Rides are saved on your iPhone, and on your Apple Watch if you use it.
- CycleTron has no server. We do not receive your rides, routes, Health data or settings.
- Location, Apple Health and saving ride maps are separate choices. You can change each one later.
- There are no ads, no tracking and no analytics SDKs. We never sell your information.
- Health data never leaves your devices and is never used for advertising or marketing.
- You can share or export any ride, and erase your rides and routes inside the app.
Who we are
CycleTron is operated by CycleTron Enterprise. For any privacy question or request, email cycletronenterprise@gmail.com.
What the app uses and why
Rides
Time, distance, speed, elevation, laps and recording status, to record, show and save your rides. They are kept on your iPhone, and on your Apple Watch when a ride uses it. Your iPhone and Watch exchange ride information directly over Apple's connection between them.
Location while you ride
Used to measure distance and speed and to draw your route, only after you allow location for CycleTron. Keeping the route map is a separate choice (the Save ride maps setting); without it, ride totals are kept without coordinates.
Apple Health data you allow
Heart rate, workouts and energy, to show live heart rate and zones and to save your ride as a workout in Apple Health. Health access is controlled in Apple's Health settings.
Bluetooth sensor readings
Heart rate, speed, cadence and power from sensors you connect. They are stored with your rides on your devices.
Your settings
Units, zones, goals, dashboards and bikes, so the app works the way you set it up. Stored on your devices.
Purchases
To unlock Premium. Payment and purchase records are handled entirely by Apple, and the app checks your purchase with Apple on your device. We never see your card or payment details. Premium follows your Apple Account; use Restore purchases on a new iPhone.
Rides you share or export
When you choose to share or export a ride (image, GPX or CSV), the file goes only where you send it. A file you save or send is under your control.
Maps, places and directions
Map tiles, place search and directions are provided by Apple Maps. The places and areas you look at are sent to Apple to answer your request, under Apple's privacy policy.
Support messages
To answer you when you write to us. Our support mailbox is hosted by Google.
Legal bases
Where the EU or UK General Data Protection Regulation applies to the support emails you send us, we process them on the basis of our legitimate interest in answering you. The app's on-device processing of location and Health data happens only with the permissions you grant, which you can withdraw at any time in Settings or Apple's settings.
What we never do
- We do not show ads or include advertising, analytics or tracking SDKs, and we do not track you across other companies' apps or websites.
- We do not sell or rent your information, or share it for targeted advertising.
- We do not upload your rides or Apple Health data, and we never use Health data for advertising, marketing or profiling.
- We do not make automated decisions about you that have legal or similar effects.
Where it is stored
Your rides, routes, settings and Health data stay on your iPhone and Apple Watch. If you use iCloud or computer backups of your iPhone, Apple includes the app's data in those backups under your Apple settings.
Apple processes maps and purchases on its own systems, which may be outside your country or the European Economic Area, under Apple's privacy policy.
How long it is kept
- On your devices: rides stay until you delete them, erase them in the app or remove the app. Apple Health keeps its own copy, which you manage in the Health app.
- Support emails are kept only as long as needed to resolve your request.
Your choices and rights
- Change location and Health access in your iPhone's Settings.
- Turn Save ride maps on or off under You › Recording preferences.
- Share or export a ride from its detail page.
- Erase your rides and routes under You › Your data, or delete a single ride from its detail page.
Because we do not hold your app data, requests about it are handled in the app itself. For support emails, you can ask us for access, correction or deletion. Email cycletronenterprise@gmail.com; we answer within one month.
You can complain to your local data-protection authority. In Romania, that is the Autoritatea Națională de Supraveghere a Prelucrării Datelor cu Caracter Personal (ANSPDCP).
These pages
These pages have no cookies, analytics, tracking pixels, forms or third-party scripts. They are hosted by Cloudflare, which processes standard request information, such as your IP address and browser details, to deliver and protect them.
Children
CycleTron is not directed to children under 16. We do not collect information from anyone through the app.
Security
Your data is protected by your iPhone's and Apple Watch's own security, such as your passcode and device encryption. Because nothing is sent to us, there is no server copy to protect or leak. Please report security concerns to our email address, without including passwords or unrelated personal records.
Changes and contact
We will update this page when our practices change, and change the date at the top. For material changes, we will tell you in the app before they apply. Any future feature that shares information, such as accounts, backup or public profiles, will be explained here before it becomes available.
