Questions & answers
Is Buko free?
Yes — Buko is free to use.
Which platforms are supported?
Native iOS and Android apps, plus a full web app at web.buko.app. Your conversations sync across all of them.
How do you handle my data?
Your chat history lives on your device, and connections are secured with TLS in transit. See our Privacy Policy for exactly what's stored and for how long.
Can I build a Bot or Kit?
Not yet. Bot integrations are not included in the current iOS release, and Bot or Kit developer access is not publicly open. Any official Kit currently shown in the app is compiled into and reviewed with that app release.
How do I delete my account?
You can delete your account and personal account data from the app settings or the Delete Account page. The server message buffer is removed within 30 days; copies already delivered to participants are outside Buko’s control.
Your own little cove awaits.
Simple, calm, and ready for your first conversation.
