2A. Instant Messaging Data
If you contact Sigma Build or Science and Construction through instant messaging software, such as WhatsApp, Telegram, or similar messaging channels, we may receive and process your phone number or user handle, display name, message contents, attachments, message IDs, timestamps, delivery status, and conversation context needed to provide support, account linking, project updates, document intake, or requested service responses.
We use instant messaging data only to operate the messaging feature, respond to your requests, maintain conversation continuity, protect the service from abuse, comply with law, and improve service quality and reliability. We do not sell instant messaging data.
Messages may be processed by the relevant messaging platform provider and by our contracted hosting, storage, security, and service providers acting on our behalf. We store messaging conversation records only for as long as needed for the purposes described in this Policy, unless a longer period is required for legal, security, fraud-prevention, dispute-resolution, or audit reasons.
2B. Google User Data
When you connect a Gmail account to Sigma Build, we use the Gmail API to access recent email metadata, including message and thread identifiers, sender and recipient details, subject lines, dates, and short message snippets. Sigma Build uses this information only to identify quote-related emails and present quote status, project association, reference, due-date, and follow-up information in the user-facing Project Tracking feature.
Sigma Build stores the connected mailbox address, authorization tokens, message and thread identifiers, sender and recipient details, subject line, received date, short message snippet, and the quote and project-tracking information derived for your workspace. Access is read-only: Sigma Build does not send, modify, or delete Gmail messages. You may disconnect a Gmail account in Sigma Build or revoke access through your Google Account settings. You may also request deletion through our User Data Deletion page.
We do not sell Google user data or use it for advertising, advertising measurement, generalized analytics, market research, or to train or improve generalized artificial-intelligence or machine-learning models. We share Google user data only with contracted service providers acting on our behalf when necessary to operate the Project Tracking feature, for security purposes, or to comply with applicable law. Those providers must protect the information and process it only according to our instructions.
Sigma Build's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
