Consumer health data notice
For Washington, Nevada and other US states with health data laws · Last updated 9 October 2026
This notice is part of our Privacy policy, for the laws that protect information about your health, such as Washington's My Health My Data Act and Nevada's law on consumer health data.
What we collect
Ka asks you nothing about your health. But anything you choose to write in your journal may be about your physical or mental health, and so may what Ka makes from it: its notes, its lines, and the words it finds.
Where it comes from
From you, and from Ka reading what you write.
Why
Only to keep your writing for you and to let Ka and plain read it and answer you, as the Privacy policy describes. Never for advertising, and never to train models.
Your consent
We collect and process it only with your consent, given in a separate box when you sign up. You can withdraw it at any time by deleting your account, or by writing to us and we will delete it.
Who we share it with
We never sell it. We share it only with the companies that process it for us, under contract, for the purposes above: the companies that host our database, server and backups (Neon, Webdock, Cloudflare, Backblaze), and the AI route and model companies named on How Ka keeps your words (through Vercel's AI Gateway). Brave receives only general search words, checked by our code against your writing first.
Your rights
You may ask to see what we hold and the list of every company it was shared with, have it deleted, and withdraw your consent. Read and delete it yourself in Ka at any time, or write to ka@interfacedelta.com: we answer within 45 days. If we refuse a request, you may appeal by replying to our answer, and, if we refuse again, complain to your state's Attorney General.
