MyoLoad privacy policy
MyoLoad turns your strength-training log into a target for every set. It is built so that your data stays on your device. MyoLoad has no accounts, no analytics, no advertising and no server of its own.
What MyoLoad stores, and where
| Data | Where it lives | Leaves your device? |
|---|---|---|
| Your workout history (from a CSV file exported from Hevy, Strong or Fitbod, or from Hevy sync), machine settings, goals, notes and preferences | On your device only (the app's local database) | No, except in a backup file you choose to save, or, on Android, when you move to a new phone with a phone-to-phone transfer |
| Progress photos and their on-device measurements | On your device only | Only if you choose: in a separate photo file you save with a password (see Backups), or, on Android, to your new phone if you use a phone-to-phone transfer. They are not included in backup files and are never uploaded. |
| Bodyweight read from Health Connect (Android), or bodyweight and height read from Apple Health (iPhone) | On your device only, alongside your workouts | No, except in a backup file you choose to save, or, on Android, when you move to a new phone with a phone-to-phone transfer |
| Your Hevy API key (optional, Hevy Pro) | Encrypted on your device with the device's secure key store | Sent only to Hevy's own service (api.hevyapp.com) to fetch your workouts and, when you confirm, update your routines |
Hevy
If you connect Hevy, MyoLoad contacts Hevy's API with your key to read your workouts and routines. "Send targets to Hevy" changes a routine only after showing you every change and only for the sets you tick. "Log a workout to Hevy" adds one new workout to your Hevy account, made from text you paste, only after you review it and press Log. Your logged workouts are never changed. Disconnecting removes the key from your device. Hevy's handling of your data is covered by Hevy's privacy policy.
Health Connect and Apple Health
Only when you connect it in Settings, MyoLoad reads your bodyweight from Health Connect on Android, or your bodyweight and height from Apple Health on iPhone. Bodyweight is used to show your lifts relative to your bodyweight and to fill in the weight on progress-photo sets; height (iPhone only) is used for the waist estimate in the photo write-up. MyoLoad never writes to Health Connect or Apple Health, never reads any other health data, and never uploads these readings. Withdrawing access in Health Connect or in the Health app removes the readings from MyoLoad the next time it opens. Health Connect data is used only for the features described here and is not used for advertising, sold, or shared with anyone.
Backups
A backup is a file you save where you choose. It contains your workouts, settings, goals and health readings so you can move to a new phone. Progress photos are never included. You can save them separately, only if you choose, in a photo file that MyoLoad encrypts on your phone with a password you pick (AES-256); without that password the file can't be opened, by anyone including us. You are responsible for where you keep backup and photo files.
On Android, MyoLoad's data is left out of Google's cloud backup, so it is not copied to your Google account. If you move to a new phone with Android's or Samsung's phone-to-phone transfer, your MyoLoad data, including progress photos, is copied directly to the new phone. Your Hevy key is not copied; connect Hevy again on the new phone.
On iPhone, MyoLoad's data is left out of iCloud backups and computer backups, so it is not copied to your Apple account. Because iPhone has no separate setting for moving to a new phone, use a backup file to move your data to a new iPhone. Your Hevy key stays on the device and is not copied.
This website
This policy is published at helixhorizonlabs.com. The site's hosting provider (Netlify) may keep ordinary server logs, such as the address of a device that loaded the page, under Netlify's privacy policy. The MyoLoad app itself sends nothing to this website.
Deleting your data
Settings → Start over → Erase everything on this device removes all MyoLoad data, including progress photos and health readings. Uninstalling the app does the same. Nothing is held anywhere else to delete.
Children
MyoLoad is not directed at children under 13 and does not knowingly collect information from them.
Changes and contact
If this policy changes, the new version will be posted at this address with a new effective date. Questions or requests about your data: email Helix Horizon Labs at helixhorizonlabs@gmail.com.
