Privacy policy

Superstream gives businesses an AI assistant for their website, turns those conversations into leads, and helps them follow up by email and on social media. This policy explains what personal data we handle, why, and what you can do about it. Questions: hello@superstream.co.

Two kinds of people

• Our customers, the businesses and team members with a Superstream account. For their account data we decide how it is used.
• Visitors who chat on a customer's website. That business decides what happens with the conversation and the lead, and we process it on their behalf. Their own privacy policy applies, and we pass any request you send us on to them.

What we collect

• Account details: your name, email address and the workspace you create. Passwords are handled by our login provider and stored only as a secure hash.
• What you add to your workspace: website content, documents, answers, branding, journeys and settings.
• Billing details through our payment provider. We never see your full card number.
• Conversations on a customer's website: the messages, the page the chat was opened on, and any details a visitor chooses to share, such as a name, email address or phone number.
• Lead profiles that we build from those conversations, with a note of where each detail came from.
• Technical data such as IP addresses, used briefly to keep the service secure and to stop abuse.

Why we use it

• To provide the service you signed up for: answering visitors, building leads, sending the emails and posts you approve, and billing.
• To keep the service secure and working, which is in our and our customers' legitimate interest.
• Follow-up emails only go to people who agreed to hear from the business, and every email has a way to unsubscribe.

AI

Answers, lead details and drafts are written by Anthropic's Claude models, and knowledge search uses Voyage AI. The text needed for each request is sent to them to produce a result. We don't use your data or your visitors' conversations to train AI models. AI answers can be wrong, which is why the assistant only answers from your own content and offers a person when it isn't sure.

Who we share it with

We use these providers to run Superstream, each only for its part of the service:

• Vercel: hosting, and access to the AI models through its AI Gateway
• Neon: database and login
• Anthropic and Voyage AI: AI answers and search
• Resend: sending email
• Stripe: payments
• PostPeer: publishing to social networks you connect

We don't sell personal data. Data is stored in the United States. Where it leaves the European Economic Area, we rely on the transfer safeguards our providers offer, such as standard contractual clauses.

How long we keep it

We keep account data while your account is open. Customers can export or erase a lead's data at any time from the lead's page. When an account is closed, we delete its workspace data, except what we must keep by law, such as invoices.

Cookies and browser storage

We only use cookies that are needed to keep you logged in. On a customer's website, the chat saves a small token in the browser so a conversation carries on from page to page. We don't use advertising or tracking cookies.

Your rights

You can ask to see, correct, export or delete your personal data, or object to how we use it. Email hello@superstream.co. If you chatted on a business's website, you can also ask that business directly. You can complain to your local data protection authority.

Changes

If we change this policy in a way that matters, we'll tell customers by email or in the app before it applies.
