Private by default
Your chats are yours. Here is exactly what happens to them.
Read the privacy policy →- Encrypted, not monetised
- Chats are encrypted in transit and at rest. Nothing is sold, nothing trains an ad profile.
- Honest about being AI
- Every companion is fictional, and every companion confirms it's AI if you ask.
- Delete means delete
- One tap wipes a conversation — or your whole account — permanently.
Questions, answered.
What's free, what's paid?
Chatting is free, with a daily message limit. Bella Plus removes the daily limit and adds more models, longer replies and longer memory. Current pricing is shown in the app before you subscribe.
Why is it 18+?
Bella is made for adults. Stories can touch mature themes, so the app is for people 18 and over.
Does it sync across devices?
Save your account in Profile, then sign in with the same account on your other phone. Your chats follow you.
