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.
- Adult content is opt-in
- Behind age verification, off by default, 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?
Unlimited text chat is free. Bella Plus adds voice calls, image replies and unlimited long-term memory. Current pricing is shown in the app before you subscribe.
Why is it 18+?
Companions can engage in adult themes once you verify your age. We'd rather gate the whole app than pretend otherwise.
Can I build my own character?
Yes — name, appearance, backstory, speech style and boundaries. Keep it private or publish it.
Does it sync across devices?
Sign in on iOS and Android and every thread, memory and companion follows you.
She's already online.
