Terms of Service
Last updated: November 2026
01Who we are and this agreement
Mantlecore is operated by EQTECH LLC (“we”, “us”). These Terms are an agreement between you and EQTECH LLC. By creating an account or using Mantlecore, you agree to them. If you don’t agree, don’t use Mantlecore.
02What Mantlecore is
Mantlecore gives you your own computers in the cloud. Each one runs on our servers and opens in your web browser. Its desktop is MantleOS, which you use like any computer. MantleOS comes with its own AI agent, Mantle, which can work on the desktop for you, and a computer can come with other agents (such as Hermes) ready to work on it too.
Mantle uses the AI models we provide (“our AI models”), paid from your prepaid balance (§9). The apps on your desktop can use your own accounts with other services.
03Your account
- You must be at least 18 and able to enter into a contract.
- Give us accurate information and keep it up to date.
- Keep your password and login methods secure. You’re responsible for everything done through your account, including everything your computers and the agents on them do.
- One person per account. Don’t share it or create extra accounts to get more free hours or credits.
04Your computer and your content
- What you put on your computers stays yours: files, apps, settings, chats.
- You give us only the permission we need to run, store, back up and show your computers to you (for example, the small picture of a desktop’s screen on your dashboard).
- We don’t look inside your computers. We only do so when you ask us for help, when we need to investigate a security problem or a breach of §5, or when the law requires it.
- Agents act for you. Anything an agent does on your computer or on the internet, it does on your behalf, and you are responsible for it as if you did it yourself. Check what you ask an agent to do, and what you let it reach.
05Acceptable use
You may not use Mantlecore, or let anyone or any agent use your computers, to:
- Mine cryptocurrency, or run any other work whose main purpose is to burn computing power.
- Send spam: bulk or unsolicited email, messages, comments, sign-ups or calls.
- Attack anything: denial-of-service, scanning or probing systems you don’t have permission to test, breaking into systems or accounts, spreading malware, running botnets or command-and-control servers.
- Steal or phish: collect passwords, payment details or personal data by deception.
- Scrape abusively: get around logins, paywalls, rate limits or blocks; ignore a site’s terms or robots rules at a scale that harms it; collect personal data in bulk without a lawful basis.
- Host or spread unlawful content: child sexual abuse material (we report it to the authorities), content that infringes others’ rights, threats, harassment, or content that promotes terrorism or violence.
- Hide other people’s traffic: run open proxies, VPN exits or Tor exit nodes for others.
- Get around our limits: bypass usage caps or payment, resell Mantlecore without our written permission, or interfere with Mantlecore or with other customers' computers.
- Break the law, or the usage policies of the AI model you use through Mantlecore.
06What we can do when something is wrong
If we reasonably believe a computer breaks §5, puts others at risk, or puts Mantlecore at risk, we may, depending on how serious it is:
- limit its internet access,
- turn it off,
- suspend your account, or
- for serious or repeated breaches, delete the computer and close your account.
We tell you what we did and why, by email, unless the law or an ongoing risk to others stops us. When harm is ongoing (an attack, spam, abuse material), we act first and tell you after. If you think we got it wrong, reply to that email and we’ll review it.
07Free hour
- Each account with a verified email can try one computer free for one hour of running time. No card is needed for the free hour. One free hour per account, ever.
- Each account can get a one-time welcome credit, in the amount shown in the dashboard, by adding a payment card once its email is verified. The card isn’t charged for it. One welcome credit per account and per card, and we may withhold it to prevent abuse. Welcome credit goes to your balance (§9) and can’t be withdrawn or refunded.
- When the hour is used, the computer is shut down. To keep it, start a plan: we ask for a card then, and the computer turns on with its files where you left them.
- If you don’t start a plan within 7 days of the hour ending, the free computer is deleted.
- Free computers are limited. When too many are in use, we may ask you to try again later or to start a plan.
08Billing
- Each computer runs on a monthly plan for its size, which includes a number of awake hours a month. The price and the included hours are shown before you create the computer. We charge the plan in advance each month through Stripe; EQTECH LLC is the seller. Prices include or exclude tax as shown at checkout.
- A computer is awake while it runs. A computer that is resting or shut down doesn’t use awake hours.
- Extra hours. After the included hours, each awake hour is charged at the hourly price shown at purchase, taken from your balance (§9), up to a monthly maximum per computer, also shown at purchase (plan price included). Once a computer reaches it, its other hours that month are free.
- Always on keeps a computer awake all month. It costs at most that monthly maximum.
- If your balance runs out after the included hours, the computer rests, with its files kept, until you add to your balance or its next month starts. Within the included hours, an empty balance never stops it.
- Plans don’t include AI credit.
- A plan renews every month until you cancel it, whether or not a computer is using it. You cancel a plan in Billing, or when you delete the computer that uses it. A cancelled plan ends at the end of the month already paid, and a new computer can use it until then.
- Deleting a computer keeps its plan, ready for your next computer of that size. Nothing is refunded or credited when you delete a computer or cancel a plan, except as described under withdrawing within 14 days.
- If a payment fails, we email you and keep trying for 7 days. If it still fails, the computer is turned off. Its disks and backups are kept for 30 days, so you can pay and turn it back on. After that, the computer and its backups are deleted.
- Shutting a computer down or deleting it doesn’t stop its plan. Only cancelling the plan does.
- Withdrawing within 14 days. When you start a plan, you ask us to start your computer at once. You can still withdraw from the plan within 14 days of starting it: email [email protected] and say which computer. You pay for the days you used, and we refund the rest to your card.
09Your balance (AI credits)
- Your account has one prepaid balance. It pays for our AI models and for a plan’s extra awake hours (§8).
- When you add to your balance, a platform fee is added. It is shown before you pay.
- Each request to one of our AI models costs that model’s price, and that amount is taken from your balance. Prices are listed on the model picker.
- If your balance runs out, our AI models stop answering until you add more. Your computers keep running within their included hours (§8).
- Your balance doesn’t expire and isn’t refundable, except where the law requires a refund.
- Welcome credit has no cash value.
10Backups and your data
- We back up each computer every day and keep backups for the period shown in your dashboard. You can restore a backup from your dashboard.
- Backups protect against our failures and your mistakes, but keep your own copy of anything you can’t afford to lose.
- Deleting a computer deletes its disks and all its backups. This can’t be undone.
11Changes and availability
- We work to keep your computers running, but we don’t promise they’ll be available all the time. We may need maintenance, and we will try to do it with little or no interruption.
- We may change Mantlecore over time. If a change takes away something you pay for, we’ll tell you by email at least 14 days before.
12Software from others
Your computers run software made by others: the operating system, apps, agents such as Hermes, and more. Each comes with its own license. AI models are provided by their makers, and their usage policies apply when you use them.
13Ending this agreement
- You can stop at any time by cancelling your plans and deleting your computers. To close your account, email us.
- We can end this agreement or suspend your account if you seriously or repeatedly break these Terms, as described in §6.
14Disclaimers and limits of liability
- Mantlecore is provided “as is”. Apart from what these Terms say, we make no promises about it.
- We are not liable for indirect or consequential losses, lost profits or lost data.
- Our total liability to you for any claim is limited to what you paid us in the 12 months before the claim.
- You agree to cover our costs if a third party makes a claim against us because of how you, or agents acting for you, used Mantlecore.
- If you are a consumer, the laws of your country may give you rights that these Terms can’t change. Nothing here limits those rights.
15Changes to these Terms
When we change these Terms in a way that matters, we email you at least 14 days before the change takes effect. If you keep using Mantlecore after that, the new Terms apply.
