Forjum Cardio mobile app — offline operation, no account, profile and planner data on your device.
Last updated: 1 October 2026
The controller of your personal data is Forjum, reachable at forjumapp@gmail.com.
Forjum Cardio helps you plan and view cardio-training-related information. Core features (profile, calculations, preferences, saving planner state) are designed so that your profile and plan data are not sent to Forjum for those purposes.
No account or sign-in is required to use the app.
Some features are paid (Premium and Pro Coach subscriptions bought through the App Store or Google Play): see “Subscriptions”.
Depending on what you enter, the device may store information such as: profile label or name, body or demographic inputs used by the planner, training goals and preferences, equipment selection, health or effort-related values you choose to provide, language and unit settings, and the saved planner state.
This information is used only to run the app on your device (calculate, display, restore after you close the app).
For example: sessions marked as done or skipped, workouts imported or entered by hand, tests and thresholds (LT1/LT2), and any medication or condition you choose to enter so the plan can account for it; with Pro Coach, also the name, studio, contact and logo you choose for PDFs.
If you allow it, the app reads from Apple Health (iPhone) or Health Connect (Android): date of birth, height, weight, resting and workout heart rate, blood pressure, VO₂max, workouts, sleep and heart-rate variability (HRV), when available. They are used only to fill in your profile, calculate your zones and compare your workouts with the plan.
These data stay on your device: they are not sent to Forjum or to third parties, not used for advertising, marketing or profiling, and never sold. The app only reads: it writes nothing to Apple Health or Health Connect. You can withdraw permission at any time in the Health or Health Connect settings.
With Pro Coach, the phone’s health data are imported only into its owner’s profile, never into other athletes’ profiles.
With Pro Coach you can create profiles for other people (your athletes or clients) and enter their data, including health data such as heart rate, thresholds or medication. These data stay on your device and Forjum does not receive them.
For these data, you decide the purposes and means of processing: it is up to you to inform the people concerned, to have an appropriate legal basis (for example their consent) and to look after the PDFs and backups you create or share.
Data is kept locally using platform-provided app storage on your phone or tablet. Forjum does not operate its own cloud archive or central database tied to day-to-day use of the app in the version described here.
Forjum does not collect your profile or plan content from the app by transmitting it to Forjum systems. The app does not use in-app behavioural analytics, behavioural advertising, or similar processing towards you in the version described here.
If you email forjumapp@gmail.com, we will process what is needed to handle your request (e.g. your address and message content) for support and communication purposes.
Premium and Pro Coach are annual subscriptions bought through the App Store (Apple) or Google Play (Google), which handle payment, renewal and cancellation as independent controllers. Forjum does not receive your card or payment details.
To know whether a subscription is active, the app asks the store for the status of your purchases (product and expiry date) and keeps a copy on the device, so it also works offline.
Reminders: if you turn them on, they are local notifications scheduled on the device; they do not go through Forjum servers.
Photos: with Pro Coach, if you choose a logo, the app accesses only the image you select and stores it in the app for your PDFs.
Files and calendar: backup files, PDFs and calendar exports (.ics) are created on the device and shared only if you decide to (for example to Files, Drive or by email); from then on, the rules of the service you choose apply.
Core planner features do not rely on uploading your personal data to Forjum servers. Your device and the app stores (Apple, Google) may carry out their own processing (updates, security, platform diagnostics) as independent controllers, under their respective policies. Installing and updating the app from a store is governed by your relationship with that provider.
Data remains on the device until you delete it in the app (profile reset or delete-data features) or uninstall the app, subject to operating-system behaviour. You can remove information at any time via the app or your device’s application storage settings.
In Settings, “Delete all data” erases every profile and plan saved in the app; with Pro Coach, your athletes’ too.
Security also depends on your device (screen lock, updates, avoiding malware). Protect your device and be careful with unprotected copies of any exports you create (e.g. backup text or files), if those features are available.
Backup files and PDFs contain personal and health data: keep them somewhere safe.
Where applicable law provides rights (including GDPR/UK GDPR), you may contact Forjum at forjumapp@gmail.com. For data that exists only on the device, deletion via the app or uninstalling is often the most direct way to remove it.
You may lodge a complaint with your local supervisory authority.
The app is not intended for children below the age at which consent for data processing is valid under applicable law. If you are a parent or guardian and believe a child has provided data inappropriately, please contact us.
