Steiner Home

Steiner Home is a private assistant for one household. Members of the household use it on their own iPhones to ask about the family schedule. It is not offered to the public and has no sign-up.

Privacy

This is the whole policy. It applies to the Steiner Home app and its use of Google Calendar.

• What it reads from Google. With a household member's permission, Steiner Home reads the list of that member's Google calendars and, for the calendars they switch on, each event's title, time and location. Access is read-only. It cannot create, change or delete anything in a Google account. Event descriptions, guest lists and attachments are not requested. Events marked private are skipped.
• Where it goes. Calendar information is stored on a computer in the household's own home and is used only to answer questions from members of that household. It is not sold, not used for advertising, and not shared with or transferred to anyone outside the household. Questions about the calendar are answered by a model running on the household's own computer. A general question, such as one about the weather, is sent as typed to Anthropic's Claude service to be answered; no calendar information is sent with it.
• How long it is kept. A stored calendar entry stops being used one year after the event. A calendar that is switched off in the app stops being read and its entries are hidden straight away.
• Ending access. A member can remove Steiner Home's access at any time at myaccount.google.com/permissions. After that, nothing further can be read.
• Google's rules. Steiner Home's use of information received from Google APIs follows the Google API Services User Data Policy, including its Limited Use requirements.
• Questions. Write to the support address shown on the Google permission screen for Steiner Home.
