Your KERN profile stores your account information and lets you personalise your identity within the app. You can access it from the bottom navigation bar or the app menu at any time.

​
What your profile shows

  • Your username and email address
  • Your profile photo (avatar)
  • Account statistics linked to your training history

​
Updating your username

1

Open your profile

Tap the profile icon in the bottom navigation bar to open your profile screen.
2

Tap your username to edit it

Tap the username field to make it editable. Type your new username.
3

Save the change

Tap Guardar (Save) to confirm. KERN updates your username and automatically issues a new JWT session token so your session remains valid.
Your username must be unique across all KERN users. If the name you want is already taken, you will see an error and your username will not change.
Changing your username causes KERN to issue a new JWT token (the username is embedded in the token’s sub claim). If you are using the KERN API directly, retrieve the new token from the PUT /users/update_name response and use it going forward. Your old token remains technically valid until its 30-minute expiry, but using it may cause inconsistencies since it encodes the old username.

​
Updating your profile photo

1

Tap your current profile photo

On the profile screen, tap your avatar image to open the photo picker.
2

Select a photo from your gallery

Choose an image from your device’s photo gallery.
3

Wait for the upload to complete

KERN uploads the image directly to Cloudinary. Once the upload succeeds, Cloudinary returns a public URL for your photo (in the format https://res.cloudinary.com/...).
4

Your avatar updates automatically

The new URL is saved to your KERN profile. Your avatar updates on screen immediately and is loaded via Glide wherever your photo appears in the app.
Your photo is hosted on Cloudinary’s CDN, which means it loads quickly on any network. You do not need to store a copy locally on your device.

​
Signing out

Tap the Cerrar sesión (Sign out) button on your profile screen to end your session. This clears the local JWT token from your device. You will need to log in again with your email and password to access KERN.
Signing out only removes the token from your device. Your account, routines, and workout history remain saved in KERN and will be there when you log back in.
