Anything at all — bugs, questions, a refund, a template you wish existed: support@kythli.com. A person reads every message and answers within a day or two. There's no phone line, because we'd rather set an expectation we can actually meet.
Yes. Email support@kythli.com within 30 days of a charge and we'll refund it in full — no questions, no form, no retention script. There's no free trial, so this is how we make trying Kythli Family risk-free. After 30 days, write to us anyway; we'd rather sort it out than have you feel stuck.
Not if you have a backup. Sign in on the new phone, then either approve it from another device you still have, or restore from your backup file — your recovery key unlocks it. Lost the key too? Sign in and we'll hand back the encrypted copy we keep for exactly this. The one thing we can't replace is the backup file itself, which is why Kythli asks you to set one up on day one.
In the app: Household → Invite. They accept by email, and your shared focuses appear on their phone. (Sharing is a Kythli Family feature.)
Your account → Plan → Manage. Cancellation is immediate at period end; nothing is deleted.
Yes — every card, every focus, from the app: Settings → Backup & restore → Export as JSON. It’s your data.
