Privacy Policy

Mantlecore is operated by EQTECH LLC, which is responsible for your personal data as described here. Contact: [email protected].

• Your account: email address, name if you give one, and a password hash. If you sign in with Google or GitHub, we also get your name, email and account ID from them.
• Billing: Stripe handles your card. We never see or store full card numbers. We keep the Stripe IDs, your plan, and your invoices.
• How you use Mantlecore: which computers you have, their size, when they’re turned on and off, how much of a managed model you used and what it cost.
• Security logs: IP addresses and requests to our website and API, kept to protect the service and investigate abuse.
• Messages you send us: support emails, the contact form, feedback.

Emails from us. We email you about your account, your computers and your bills; those are part of the service. Product news, tips and blog posts we send only if you said yes: at sign-up (the box starts unticked where the law asks for that, such as the EU and the UK) or later in your settings. Every such email has an unsubscribe link, and saying no changes nothing else.

Your files, apps, browser data, chats and settings are stored on your computer’s disks on our servers. They are yours. We don’t look at them, except when you ask us for help, when we need to investigate a security problem or abuse (see the Terms), or when the law requires it.

Pictures of your screen. To show a desktop on your dashboard, we take a small picture of its screen while the dashboard is open. It is kept briefly on our servers to serve the page, then replaced by the next one. It is not shared or used for anything else.

When an AI works on your desktop. If you ask Mantle, MantleOS’s own agent, or another agent, to work on your desktop, it sends pictures and text from your screen to the AI model you chose, so the model can see what it is doing. When the model you chose for Mantle can’t see pictures, Mantle sends its pictures of your screen to the vision helper shown in your computer’s settings instead (DeepSeek Flash, unless you pick another or turn it off) and works from its description.

What you ask Mantle. When you give Mantle a task, on your computer or from your dashboard, we keep the conversation (the task, the steps it took and the result) in that computer’s history, so you can see it and carry on later. Pictures of the screen are not kept. When you delete a conversation on your computer, it is deleted from the computer and from our records. Backups made before you deleted it still hold it until they expire: your computer’s backups (restoring one brings the conversation back to your computer) and our own (section 6). Deleting the computer deletes its whole history.

We use a few strictly necessary cookies to keep you signed in and secure.

With your consent, we also use Google Analytics to see how our site is used. Its cookies are set only after you opt in.

Ads. We advertise online. If you allow Marketing cookies, our advertising partners may show you our ads on other sites and apps. We honor Global Privacy Control. You can change this anytime in “Cookie settings”, which also lists every cookie we use.

We may also record how our website and dashboard are used (pages visited, clicks, errors) to fix problems and improve Mantlecore. Passwords and other sensitive fields are masked and never recorded. Where the law requires consent, we ask for it first.

• Your accounts in your apps: the sign-ins and keys you use in the apps on your computer stay inside it. We don’t store or see them.
• Managed models: what you or your agents send to a managed model (prompts, files, screen pictures) is sent to the provider of the model you picked or, for a picture of your screen Mantle’s vision helper looks at (section 3), to that model’s provider (see Subprocessors). We don’t keep the content, apart from Mantle’s task history on your computer (section 3). We only record how much each request used and what it cost, for your bill. The provider handles the content under its own terms and privacy policy.

We back up each computer every day. Backups are encrypted, may be stored in a different region from your computer, and are kept for the period shown in your dashboard. When you delete a computer, its backups are deleted too.

We also back up our own records, such as your account and Mantle’s task history, every day so we can recover if something fails. These backups are encrypted, kept for up to 12 months and used only for that. They are never restored to your computer.

Your computer runs in the region shown when you create it. Backups may be stored in a different region. Some of the services we use are based outside the EU, mostly in the United States. When data goes to them, we rely on the safeguards the law requires.

The services we use, what for and where, are listed on our Subprocessors page.

We don’t sell your personal data, and we don’t share it with anyone except as described here or when the law requires it.

• Account: until you ask us to delete it.
• Computers: until you delete them. If a payment fails and isn’t fixed, the computer and its backups are deleted 30 days after it was turned off. A free computer whose hour has ended is deleted 7 days later, unless you start a plan (see the Terms).
• Your computers’ backups: for the period shown in your dashboard, and never longer than the computer exists.
• Our own backups: up to 12 months.
• Mantle’s task history: until you delete the conversation or the computer.
• Security logs: up to 30 days.
• Billing records: as long as tax law requires.

You can ask us to show, correct, export or delete your personal data, or object to how we use it. Email [email protected] and we’ll answer within 30 days. Deleting a computer from your dashboard deletes its disks and backups right away. To delete your whole account, email us. If you’re in the EU or UK, you can also complain to your data protection authority.

Mantlecore is not for anyone under 18, and we don’t knowingly collect their data.

If we change this policy in a way that matters, we’ll email you before the change takes effect.
