Your content

You own what you post. To run the service, you give LainCorp a worldwide, non-exclusive, royalty-free licence to store, copy, relay, display and distribute your content, for as long as it's on our relays.

Public content may be copied by other users and relays outside our control.

Posts and their media are stored for 30 days. The top posts of each month are kept indefinitely. See the Privacy policy.

Moderation

We may remove content, block media and suspend or ban accounts that break these terms or the guidelines, and we may report illegal content to authorities. The app enforces our moderation list on all content, whichever relay it comes from.

Lain, the AI companion

Lain's replies are generated by an AI model on your phone and can be wrong. Don't rely on them for medical, legal, financial or safety decisions. You can report any reply.

Acceptable use

Don't:

No warranty

Lain IO is provided “as is”. To the extent the law allows, LainCorp isn't liable for indirect or consequential losses, or for content posted by others.

Ending

You can delete your account at any time. We may end access for accounts that break these terms.
