Do you own your keys on Atomic Wallet?

Hello there, I'm just curious about something related to Atomic Wallet. Could you please clarify something for me? As a professional practitioner in the field of cryptocurrency and finance, I'm always keen on understanding the intricacies of digital asset management. So, my question is - do you personally own the keys to your cryptocurrencies when they're stored in Atomic Wallet? I've heard conflicting opinions on this matter, and I'd really appreciate it if you could shed some light on this for me. Thank you in advance for your time and assistance.
