1. In short
EllioFit is a workout tracker that runs entirely on your phone. There is no account and no sign-up. The app does not send your workouts, heart rate or any other personal data to us or to anyone else, and it contains no analytics, advertising or crash-reporting tools.
This policy covers the EllioFit app for Android and this website.
2. Who we are
EllioFit is published on Google Play by Svitlana Rubizhenko (“we”, “us”), the data controller for the purposes of this policy.
3. What the app keeps on your phone
To do its job, the app stores the following only on your device:
- Workouts — date, duration, distance, calories, speed, cadence, power, resistance, heart rate and the charts of each session, including workouts you add by hand;
- Your date of birth — only if you enter it under Profile → About you. It is used to estimate your heart-rate zones and for nothing else;
- Machines you've connected to — their Bluetooth name and identifier, so the app can reconnect to them;
- A technical log — if the app runs into an error, a short record of it and of the events just before it, kept for up to three days so you can send it to support if you choose;
- Settings — your workout goal, app preferences and the date you first opened the app.
Heart rate and workout data are health and fitness data. The app never sends them anywhere.
4. Bluetooth
The app uses Bluetooth only to find fitness machines that support the Bluetooth FTMS standard, connect to them and read the workout data they send. It does not use your location. On Android 11 and older the system requires the location permission for any Bluetooth scan; the app does not read or store your location.
5. What we receive
Nothing from the app itself. It makes no network requests — it doesn't even have Android's permission to access the internet. We have no servers holding your data, so we can neither see nor restore it.
We only receive what you choose to send us: an email to support (see “Contacting us”) or a diagnostics report you send from Profile → Settings → Diagnostics.
A diagnostics report contains the app version, your phone's Android version and language, and a technical log of recent events — the data your machine sent, connection steps and errors — with Bluetooth addresses removed. It contains no workout history and no date of birth. The app opens it in your own mail app, so you can read it before you send it.
Google Play gives app developers aggregated statistics, such as the number of installs, and crash reports from people who allowed their device to share them. Google provides these under its own policy; they don't identify you to us.
6. Backups and moving to a new phone
Because your data lives on the phone, deleting the app or losing the phone deletes it. If your phone's Google backup is turned on, it may include the app's data. That backup is handled by Google under its policy — we have no access to it.
7. Deleting your data
- Remove your date of birth in Profile → About you;
- Forget a machine in Profile → Settings;
- Delete everything at once by uninstalling the app.

8. Contacting us
If you write to us — by email, or through the form on our website, which opens your own mail app — we receive your email address and whatever you include in the message. An email you start from the app's Contact support also names the app version and your machine's Bluetooth name in its subject line. We use all of this only to reply, keep it only as long as needed to handle your request, and delete it when you ask.
9. This website
The website sets no cookies and runs no analytics or advertising trackers. It remembers your language choice in your browser's local storage; that value never leaves your browser. Fonts are served from our own site, not from third parties.
As with any website, our hosting provider may keep standard server logs — such as IP address, browser type and the page requested — for security and reliability.
10. Age
EllioFit is intended for people aged 18 and over. The app is not directed at children, and we do not knowingly receive data from anyone under 18.
11. Your rights
The app's data stays on your device, so you are always in control of it. For anything you have sent us, such as support emails, you can ask us for access, correction or deletion at support@elliostudio.com — we reply within 30 days. You can also complain to your local data protection authority.
12. Changes to this policy
If the app ever starts processing data beyond your phone — for example optional accounts, cloud backup or paid features — or comes out on another platform, we will update this policy before that version is released. The date at the top of the page shows the latest revision.
