We are very sorry that you lost your trackle in the toilet.
As we explicitly state in the instruction manual that the trackle must be removed before going to the toilet, this is unfortunately not a warranty case and you will have to purchase a new sensor if you want to continue using trackle.
Take a look at our sho! We have special offers time and again where you can buy the trackle at a reduced price.
Your data is stored in your account and will be preserved. You can simply link your new trackle to your account.
