YOUR PRIVACY
What we keep.
What we don’t.
Two notices on one page: the iPhone app, which keeps your training on your iPhone, and this website, whose contact form stores messages in our database.

IPHONE APP 1.0.0 · OFFLINE RELEASE
Virtuski iPhone App Privacy Policy
Updated 27 October 2026
This applies to the offline iPhone release 1.0.0. App data stays on your iPhone; it is separate from website contact-form messages, described further down.
Information on your iPhone
Your local profile, body mass, optional profile details, workouts, settings, course sessions and machine recordings are stored on your iPhone. Use a nickname; a real name or email address is not needed. Body mass sets rider physics and watts per kilogram. Power, stroke rate, heart rate and remembered Bluetooth device identifiers are used for your training and device reconnection.
Bluetooth and location
Bluetooth starts when you enable it in Devices. Virtuski reads the Concept2 PM5 SkiErg you confirm and the compatible heart-rate strap you select. It does not change machine workouts or settings. You can disconnect, forget a device or turn devices off. Virtuski does not request GPS location; the map shows a virtual course, not your location.
Sharing and tracking
This release does not automatically upload your profile, recordings, analytics or diagnostics to us. It contains no advertising or cross-app tracking. A TCX export leaves the app only when you choose to share it with another app or recipient. Heart rate is excluded from course exports by default; no GPS positions are included. The app or recipient you choose handles any shared copy under its own policy.
Retention and removal
Saved information stays locally until you change it or remove the app. Discarding an unsaved course session does not remove earlier sessions. To remove Virtuski's local profile and recordings, use iPhone Settings > General > iPhone Storage > Virtuski > Delete App. Offload App keeps documents and data. Apple may retain device backups under your iCloud or computer backup settings; manage those separately. Exported or shared copies must be removed at their destination. There is no hosted account to delete in this release.
Your choices and support
You can edit your local profile, leave optional profile fields empty, decline Bluetooth and use clearly labelled simulated Demo input, or turn off heart-rate exports. For privacy questions or support, use the contact form at https://virtuski.com/support. Information you voluntarily include in a support message is used to answer your request. Avoid sending passwords or unnecessary personal or health information.
Apple services
App distribution, device backups, permissions and any diagnostics you choose to share through Apple are governed by Apple's settings and policies. We do not add an automatic diagnostics upload to this release.
WEBSITE PRIVACY
The virtuski.com contact form.
What you tell us
The website contact form asks for three things: your name, your email and your message. Nothing else is asked for, and nothing else arrives with it.
Where it goes
Website contact messages are saved in our own database so they cannot be lost, and a copy is emailed to the person who runs Virtuski so that someone can answer you.
What we do not do
virtuski.com sets no advertising or tracking cookies, loads no analytics script, and does not sell, rent or pass on your details to anyone.
How long we keep it
Website contact messages are kept until you ask us to delete them. This covers only messages sent through the website form — the iPhone app does not upload training data to us. There is no newsletter and no marketing list.
How it is guarded
The site is served over an encrypted https connection, and the place your message is kept is not open to the public.
If this ever changes
If we start collecting something new, this page says so first — with the date it changed. Nothing is added quietly.
DELETIONS AND COPIES
Ask and it is done.
Want a website message deleted, or a copy of what we hold about you? Write through the contact form on the support page and say which — we will confirm once it is done.
