Privacy policy

Last updated: 28 September 2026

This policy covers the Enhanced Training Studio app and this website. The short version: your health and training data stays on your device, and we never receive it.

What stays on your device

Everything you log in the app stays on your phone: doses, schedules, lab results, workouts, routes, health data read from Health Connect, and your profile. We have no copy and can't see it.

What we do receive

WhatWhyHow long
Licence key, random device ID, device name, app versionTo activate your licence and manage your 3 device slotsWhile your licence exists
Order details from BTCPay (amount, time, invoice ID)To issue and look up your licenceAs long as tax law requires
Your email, only if you give it at checkoutTo send your receipt and help you find your keyUntil you ask us to delete it
Basic web server logs (IP address, pages requested)Security and keeping the site runningUp to 30 days

We don't use analytics, advertising or tracking cookies, and we don't sell or share data with anyone.

Payments

Payments go through our own BTCPay Server. We don't handle cards. A Bitcoin transaction is recorded publicly on the blockchain by its nature; we don't link it to anything beyond your order.

Google Drive backups

If you turn them on, backups go to a private app folder in your own Google Drive. Only the app on your phone can read them; we can't. Google's privacy policy applies to your Google account.

Health Connect

The app reads the data types you choose from Health Connect, only to show them to you on your device. It doesn't write to Health Connect, and the data isn't sent anywhere.

Maps

When you view a route, map tiles are loaded from OpenStreetMap, which sees the map area being requested.

Your rights

You can ask us what we hold about your licence, and ask us to correct or delete it, by emailing support@enhancedtraining.app. Deleting your licence record means it can no longer be activated.

Changes

If this policy changes, we'll update the date above and note the change in the changelog.

Buy a licence

You'll pay with Bitcoin or Lightning on the next page. Your licence key appears as soon as the payment confirms.

Leave it blank to buy without giving an email. Then copy your key from the page when it appears.
