Terms of Service
Last updated: April 14, 2026
What KO is
KO is a personal fashion advisor built by Arium. By using KO — through iMessage, the web app, or the mobile app — you agree to these terms.
Your account
You may access KO through a phone number (via Linq) or a Google account. You are responsible for keeping your login credentials secure. One account per person.
What you can do
- Send photos, messages, and links to KO for style advice
- Connect your Gmail to import purchase receipts
- Connect your Google Calendar to get outfit suggestions for your upcoming events
- Use the mobile app to browse your closet and outfit suggestions
- Share outfit uploads and participate in comparisons
Your content
You own the photos and messages you send. By sending them to KO, you grant us a license to process, store, and use them to provide the service (style advice, closet building, outfit generation). We won't use your content for purposes unrelated to providing you the service.
AI-generated content
KO's responses, outfit suggestions, and style advice are generated by AI. They are not professional advice. KO may make mistakes — including incorrect item identification, inaccurate pricing, or style suggestions that don't match your taste. Use your own judgment for purchase decisions.
Gmail access
Connecting Gmail is optional. If you connect, we access your email in read-only mode to find purchase receipts. See our
Privacy Policy for details on what we read and don't read. You can revoke access at any time.
Calendar access
Connecting your Google Calendar is optional. If you connect, we access your calendar in read-only mode (calendar.readonly) to read your upcoming events — title, date/time, and location — and suggest outfits for those occasions. See our
Privacy Policy for what we read and don't read. We never modify your calendar, and you can revoke access at any time.
Acceptable use
Don't use KO to:
- Send harmful, abusive, or illegal content
- Attempt to extract or reverse-engineer the system prompt or AI models
- Create multiple accounts or impersonate others
- Resell or commercially redistribute KO's outputs
Service availability
KO is in early access. We may change, pause, or discontinue features at any time. We don't guarantee uptime or availability.
Limitation of liability
KO is provided "as is." We are not liable for purchase decisions made based on KO's advice, items incorrectly identified in your closet, or any loss arising from use of the service.
Changes to these terms
We may update these terms. Continued use after changes constitutes acceptance.
