Your data.

What lives on your device#

Your logs, your chats, the coach's memory of you, your decisions log, your photos and your connection tokens: all of it is stored on your device, per account. Settings and structured logs live in localStorage; larger content such as photos lives in IndexedDB. Our servers never receive or keep any of it.

The little we hold#

• Your account basics: email and sign-in timestamps.
• App-open counts and when you were last active.
• Aggregate AI usage numbers for fair use: never what was said.
• An abstract persona sketch computed on your device: an archetype word plus coarse traits. It helps us make Kata better and cannot be traced back to your content.
• Your invite state and your plan.

Never on our servers: your chats, your logs, your photos, the coach's memory, your decisions. And there is no analytics profile, no ad pixel, no selling, ever.

When you talk to the coach#

Your message, plus the minimum context needed to answer it, travels encrypted to generate the reply and is processed transiently: it is not stored on our side. Voice is transcribed and photos are analyzed the same way, only when you send them. See How it reads your data.

Export, wipe and delete#

Settings, Data, Export gives you one file with everything: treat it as your backup, or use the built-in Backup and restore. Wiping the device clears everything locally, completely and instantly. Deleting your account additionally removes your email and invite records from our systems: after that, nothing about you remains anywhere.
