Gemini is freemium — a usable free tier with paid plans above it. Proton Lumo is freemium — a usable free tier with paid plans above it. Both are listed under General Purpose Chatbots, so this is a like-for-like comparison. Neither is ranked above the other — Flocci carries no sponsored placement.
Gemini is freemium — a usable free tier with paid plans above it and is listed for free tier on Gemini 3.x Flash models, with limited access to the top Pro model.

Both sit in General Purpose Chatbots.
Neither — Gemini and Proton Lumo are both freemium, so the choice comes down to capability rather than cost. Both entries list what they uniquely do above.
Choose Gemini if you need free tier on Gemini 3.x Flash models, with limited access to the top Pro model; choose Proton Lumo if you need zero-access encrypted chat from the makers of Proton Mail/VPN — no account needed to start chatting.
