Your private kennel
Your data is stored privately on this device only (in this browser's storage). It is never sent to the cloud, to a server, or to any other dog.
That also means nobody else has a copy. Clear your browser data, switch devices or lose this one, and your notes are gone. If it matters, back it up with Export, and keep that file somewhere safe.
A backup can be brought back with Import, but importing overwrites ALL existing data on this device. You will be asked to confirm first.
