Privacy policy

What we collect

• Account details. Your email address, first and last name, and how you signed up (email, Google or Apple). Google and Apple sign-in run through Privy, and we receive your email and, where the provider shares it, your name. If you use a password we keep only a bcrypt hash of it.
• Waitlist. Your email address, your place in the queue, your referral code and who referred you, and how you found us: campaign tags such as utm_source, ad click IDs and the referring site. Your browser keeps those tags for up to 90 days so they can be attached when you join.
• Trading. Your Hyperliquid wallet address and the API wallet you approve for Antei (its key is encrypted and never shown to strategy code), plus the strategies, code and settings you upload, backtests, deployments, orders, fills, positions and logs. Hyperliquid is a public blockchain, so activity on it is public by nature.
• AI assistants. When you connect Claude, Codex or another assistant to our MCP server, we keep the OAuth client and the access you granted, and process the requests your assistant sends for you.
• Email. When we email you (sign-in codes, account and waitlist messages), we record delivery and whether the message was opened (through a small image) or a link was clicked (links pass through antei.ai). Messages you send to an @antei.ai address are stored so we can read and answer them.
• Usage and device data. Our servers log the IP address, browser (user agent), page requested and time of each request to run and protect the service. We also use Google Analytics, described next.

Google Analytics and cookies

We use Google Analytics 4 (measurement ID G-B685DB3XW2) to understand how people find and use antei.ai. It sets first-party cookies (_ga and _ga_B685DB3XW2) and sends Google the pages you view, the referring site, device and browser details, and an approximate location derived from your IP address. Before a page address is sent, our site strips everything except the path and campaign tags, so sign-in codes, invite codes and similar values never reach Google. The admin panel, the sign-in return page and the MCP approval page do not load Google’s tag at all.

We use Google signals, a Google Analytics Advertising Feature. For visitors signed in to a Google account with ad personalization turned on, Google associates this data with that account so we can see aggregated, anonymous reports on demographics, interests and use across devices. For these features Google and we use first-party cookies such as the Google Analytics cookie together with third-party cookies such as Google advertising cookies. We never receive your Google account details.

You can opt out at any time:

• install Google’s Analytics opt-out browser add-on;
• turn off ad personalization in My Ad Center;
• block or delete cookies in your browser settings.

How Google uses data from sites that use its services: policies.google.com/technologies/partner-sites.

The site also keeps your session token and a few preferences in your browser’s local storage, and sets a small cookie that only records that you are signed in, so pages can send you to the right place.

How we use it

• to run the service you ask for: accounts and sign-in, backtests, and the strategies, orders and deployments you start;
• to email you sign-in codes, service messages and waitlist updates, each marketing email with an unsubscribe link;
• to understand and improve the product, including through Google Analytics;
• to keep the service secure and prevent abuse and fraud;
• to meet legal obligations.

We do not sell your personal data.

Who we share it with

Service providers that process data for us, only for the purposes above:

• Hetzner, which hosts our servers in Singapore;
• Privy, which runs Google and Apple sign-in;
• Resend, which delivers our email;
• Google, for Google Analytics;
• AI model providers, for the content you submit to an AI-assisted feature.

Hyperliquid receives the orders you place through Antei. We may also disclose data when the law requires it, to protect people or the service, or as part of a merger or acquisition, in which case this policy continues to apply.

Where it is stored and for how long

Our servers are in Singapore. Our providers may process data in other countries, such as the United States and Japan, under their own safeguards.

We keep account and trading data while your account is open, and afterwards only as long as needed for legal, accounting or dispute purposes. Waitlist data stays until you join or ask us to remove it. Server logs are kept for a short period. Google Analytics keeps user-level data for the retention period set on our property (currently two months); aggregated reports are kept longer.

Your choices and rights

You can ask us to access, correct, export or delete your personal data, or to restrict or object to how we use it. Email hello@antei.ai from the address on your account and we will reply within 30 days. You can unsubscribe from marketing email with the link in any message, and opt out of analytics as described above. If you are in the EU or UK you can also complain to your data protection authority.

Security

Traffic to antei.ai is encrypted with HTTPS, stored exchange credentials are encrypted with AES-256-GCM, and access to production systems is restricted. No system is perfectly secure, so please tell us at hello@antei.ai if you find a problem.

Children and changes

Antei is not for anyone under 18.

If we change this policy we will update the date above, and for material changes we will tell you by email or on the site before they take effect.
