Hello ❦Carpe⇸diem❧,
Yes, there is a way to keep them.
The buddies you add are stored in the so called "cookies" or "browser cookies"
If you clear your browser's cache, or if your browser is set to automatically clear its cache upon closing, the cookies will also be deleted, and your buddies are gone.
To keep them you want to make sure, that your browser is not set to delete its cache after each session. This setting can be found in your browser's security settings
Kind regards and
Happy Holidays to you as well!
John Stewart
