Google Calendar AI data disclosure

AI-assisted calendar responses

When you start a conversation and ask a calendar-related question, Hotmind may send only the calendar events relevant to your request to the OpenAI API. Relevant event information may include the event title, date and time, location, and recurrence information. OpenAI uses this information only to generate the spoken response you requested.

Connecting Google Calendar does not by itself send calendar data to OpenAI. Hotmind does not transfer Google Calendar data to OpenAI continuously, independently, in the background, or in bulk, and does not use it for advertising, profiling, sale, or AI model training.

By agreeing to this Privacy Policy, or by starting or continuing to use our Products or Services without contacting us to express a contrary opinion, you will be deemed to have fully understood and agreed to this Policy.

Google API disclosure

Google Calendar Data

When you choose to connect Google Calendar, Hotmind accesses Google user data only to provide the calendar features that you request. This section applies specifically to Google user data and controls if it conflicts with a more general statement elsewhere in this Policy.

Data We Access

  • Your Google account identity information, such as your email address and basic profile information, to identify and manage the calendar connection.
  • Calendar list metadata, including calendar identifiers, names, colors, settings, and access roles, so you can choose which calendars to connect.
  • Calendar event data from calendars you select, which may include event titles, descriptions, dates and times, time zones, locations, recurrence rules, reminders, attendees, and event status.
  • OAuth authorization tokens and synchronization metadata needed to maintain the connection and detect calendar changes.

How We Use Google Calendar Data

  • To display the calendars and schedules you select in the Hotmind App and on Hotmind devices linked to your account or family.
  • To provide reminders and other user-facing schedule features that you request.
  • For a read-only connection, to import or display selected Google Calendar events without changing them in Google Calendar.
  • For a two-way connection, to create, update, or delete events in Google Calendar when you perform the corresponding action in Hotmind, and to reflect Google Calendar changes in Hotmind.
  • To maintain and troubleshoot the calendar synchronization service, protect it from abuse, and comply with applicable law.

AI-Assisted Calendar Responses

When a user initiates a conversation and asks a calendar-related question, Hotmind may use the OpenAI API to generate a spoken response. OpenAI may invoke a Hotmind calendar tool to retrieve only the calendar events relevant to the user's request. The tool result may include limited event information such as the event title, date and time, location, and recurrence information. This information is used solely to generate and deliver the requested spoken response.

Hotmind does not continuously or independently transmit Google Calendar data to OpenAI merely because a calendar account is connected. Google Calendar data is not sent to OpenAI for background analysis, bulk processing, advertising, profiling, sale, or AI model training.

Hotmind does not use Google Calendar data for AI model training, advertising, or sale.

Storage, Security, and Retention

Hotmind stores OAuth access and refresh credentials in encrypted form. Calendar and event data needed for the feature is stored in protected cloud systems and may be cached on your Hotmind App or linked devices. We retain Google Calendar data only for as long as needed to provide the connection you requested, meet security and legal obligations, or resolve disputes. When you disconnect a calendar, future synchronization stops. Depending on the removal option you choose, previously synchronized events may be deleted or retained as local Hotmind events. Account-deletion requests are handled as described in Section 6 of this Policy.

Sharing and Human Access

Google Calendar data is shared only as necessary to provide visible Hotmind features that you authorize. This may include showing selected schedules to family members or linked Hotmind devices that you have authorized, and processing by cloud or infrastructure providers acting on our instructions under confidentiality and security obligations. We do not transfer Google Calendar data to advertising platforms, data brokers, or information resellers. Our personnel do not read Google Calendar data except with your affirmative consent, when necessary for security or abuse investigation, when required by law, or when data has been aggregated for permitted internal operations.

AI Service Provider

Hotmind uses the OpenAI API as a third-party AI service provider for user-initiated conversational features. Relevant Google Calendar event information is transmitted to OpenAI only when the user asks a calendar-related question and only to generate the requested spoken response. Hotmind has not opted in to OpenAI API data sharing or model training. Google Calendar data is not used by Hotmind to create, train, or improve generalized or personalized AI or machine learning models.

Your Controls

You can choose which calendars to connect, select read-only or two-way synchronization where available, disconnect your Google account in Hotmind, revoke Hotmind access from your Google Account security settings, and request deletion through the account controls described in this Policy or by contacting app@hotmind.ai.
