Privacy Policy

Last updated: November 4, 2026

This policy explains what TensorBlock ("we", "us") collects when you use LagrangeCloud (the website, console, API, CLI, plugin and the agents you run), how we use it, and the choices you have.

#What we collect

Account information. Your email address, name and profile picture from the sign-in provider you use, the organizations and projects you belong to, and invitations you send. If you sign in with an email and password, we store a hash of the password, never the password itself.

Your content. What you deploy and run: agent instructions, skills, files, MCP server settings, secrets, run inputs, outputs, traces (each step, tool call and model call), files in sandboxes and instances, schedules, webhooks and callbacks. This can include personal data if you or your agents' callers put it there.

Usage and billing. Runs, token counts, model and compute costs, instance uptime, your credit balance and charges, and which improvement proposals you open in the console and what you decide on them.

Technical data. IP addresses, request logs and error logs from our servers, used to run, secure and debug the Service.

Campaign links. When you open our site from a link tagged with campaign parameters (utm_source, utm_medium, utm_campaign), we count the visit for that campaign without recording who you are, and remember the campaign in a cookie for up to 30 days. If you then create an account, we save the campaign with it.

We don't use advertising trackers or third-party analytics.

#How we use it

• To run the Service: store your agents, run them in sandboxes, send their prompts to model providers, deliver results, and show you traces.
• To bill you and enforce limits.
• To produce Improvements for your own agents: we analyse your agents' runs to propose changes (a cheaper model, better instructions, fixes for tool calls that keep failing), which you review before anything goes live. Replays of earlier inputs only run when you approve them.
• To see which of our campaigns bring people who go on to use the Service, from the campaign saved with your account and whether you have run an agent.
• To keep the Service secure, prevent abuse, and fix problems.
• To contact you about your account, billing, security and changes to these policies.

We don't sell your data, and we don't use your content to train AI models.

#Who we share it with

We share data only with the service providers that help us run the Service, and only what they need:

Your agents also send data to the MCP servers, APIs and websites you connect them to. That is under your control and governed by those services' own terms.

We may disclose data if the law requires it, to protect the rights and safety of our users or others, or as part of a merger or sale of our business, in which case this policy continues to apply to it.

#Security

Traffic to the Service is encrypted with TLS. Data is stored on encrypted disks, and backups are encrypted. Each run executes in its own isolated sandbox. Secrets are only given to your own agents' runs and are never shown again after you save them. No system is perfectly secure; if we learn of a breach that affects your data, we'll tell you without undue delay.

#How long we keep it

We keep your account and content while your account is open. When you delete something in the console, it is removed from the live system; database backups are kept for up to 30 days and disk snapshots for up to 7 days, after which deleted data is gone from them too.

When you ask us to delete your account, we delete your account and content within 30 days, apart from billing records we must keep by law.

#Your choices and rights

You can see and change most of your data in the console. To get a copy of your data, correct it, or delete your account, email contact@tensorblock.co. Depending on where you live, you may have further rights, such as to object to or restrict processing, or to complain to a data protection authority. We'll respond within 30 days.

#Data you process for others

If your agents process personal data about other people (for example, your customers' messages), you decide what is processed and why, and we process it only to run your agents for you. You are responsible for having a lawful basis and giving those people any notice the law requires.

#Cookies and local storage

We use a few cookies and browser storage entries that the Service needs to work: a session cookie that keeps you signed in, a short-lived cookie during sign-in, Clerk's sign-in cookies, and local storage for your theme and, if you sign in with an API key, that key. If you arrive from a campaign link, a first-party cookie remembers that campaign for up to 30 days, until you create an account. We don't use advertising cookies.

#Children

The Service isn't for anyone under 16, and we don't knowingly collect their data.

#International transfers

We and our providers may process data in the United States and other countries. Where the law requires it, we rely on appropriate safeguards for those transfers.

#Changes

We may update this policy. We'll change the date at the top and, for material changes, tell you by email or in the console before they take effect.
