Privacy Policy

Last updated: August 2026

Who we are

TxID is a product operated by 3UILD, a United States company. 3UILD is the data controller for the personal data described below, and “we” and “us” on this page mean 3UILD.

Where a protocol installs the Service on its own site, that protocol is the controller of its end users' data and 3UILD processes it on their behalf.

What we collect

When you use TxID, we collect:

  • Account data: your email address and name, via Clerk authentication
  • Project configuration: branding settings, smart contract addresses, and documentation you index
  • Agent conversations: messages sent by your end-users to the agent, stored to power analytics and improve the AI
  • Usage data: conversation counts, timestamps, and satisfaction ratings

Wallet addresses

The agent reads the public wallet address of connected wallets to provide personalized support. We store wallet addresses only as part of conversation records. We never request private keys, seed phrases, or signing permission beyond what the user's own site already has.

How we use your data

  • To provide and improve the Service
  • To generate analytics visible in your dashboard
  • To train and fine-tune AI models (conversation data only, anonymised)
  • To send important Service updates (no marketing without consent)

Third parties

We use the following sub-processors:

  • Anthropic: AI inference (Claude)
  • Voyage AI: document embeddings
  • Supabase: database and storage
  • Clerk: authentication
  • Moralis: on-chain data
  • Vercel: hosting

Data retention

We keep conversation data for as long as the project it belongs to is active. A support record exists so the protocol can answer for what its assistant told a user, so it stays useful for as long as they run the service. When a project is deleted, its conversations go with it.

We do not currently run an automatic deletion schedule, and we would rather say that than publish a period we do not enforce. Retention periods you can configure, applied automatically, are on our roadmap and are listed as not built on our Trust page.

You can request deletion of your account and its data at any time by emailing us. Deletion is recorded rather than silent: an erased conversation leaves behind a marker showing that a record existed and was erased, containing no personal data. That is deliberate, so a gap in a record set is never unexplained.

Your rights

You have the right to access, correct, or delete your personal data. To exercise these rights, contact 3UILD at team@txid.support

Cookies

We use only essential cookies: those strictly necessary to operate the service. We do not use advertising, tracking, or analytics cookies.

  • Authentication cookies: set by Clerk to keep you signed in to the dashboard. These expire when you sign out or after 30 days of inactivity.
  • Session preference: a single localStorage entry records that you have acknowledged this notice. It contains no personal data and is stored in your browser only.

The support agent uses sessionStorage (not cookies) to hold the active conversation. This is cleared automatically when the browser tab is closed and is never sent to our servers except as part of a conversation message.

Because we use only essential cookies, no consent is required under UK/EU law, but we show a notice as good practice. You can clear cookies at any time through your browser settings; this will sign you out of the dashboard.

Changes

We may update this policy. We'll notify registered users of material changes by email.
