Terms of Service

Last updated: October 13, 2026

These terms cover your use of 0bridge: the hosted gateway at 0bridge.dev and the 0b command-line tool. By signing in or using the service you agree to them. If you use 0bridge for an organization, you accept these terms for that organization.

These terms are between you and 0bridge (support@0bridge.dev, privacy@0bridge.dev), which runs the service from the Republic of Korea ("we", "us"). You can also reach us through the contact form.

What 0bridge does#

0bridge gives your AI tools one MCP endpoint. You connect services (for example Linear or Notion) to your 0bridge account, and tools you authorize (for example Claude Code, Codex, Cursor, Claude or ChatGPT) reach those services through it. The 0b tool also keeps MCP servers, skills and instructions in sync across the AI tools on your computer.

Your account#

  • You sign in with an email code, a passkey, Google or GitHub. Keep access to that email, passkey or account secure; anyone who controls it can control your 0bridge account. If you add a passkey, keep your recovery codes somewhere safe.
  • You are responsible for what happens through your account, including actions AI tools take with the services you connect.
  • You can revoke any device token or authorized app, and disconnect any service, at any time.

Connected services#

  • When you connect a service, you authorize 0bridge to act on your behalf with the permissions that service grants. Your use of each service is still governed by that service's own terms.
  • Only connect accounts you are allowed to use. Do not use 0bridge to share accounts or credentials in ways a service's terms prohibit, or to get around a service's rate limits, pricing or access controls.
  • AI tools can take real actions (creating issues, sending messages, changing data). Review what your tools do; 0bridge passes their requests through and does not check whether an action is what you intended.

Acceptable use#

Do not use 0bridge to:

  • break the law or infringe anyone's rights;
  • access accounts, systems or data you are not authorized to access;
  • probe, overload or disrupt the service or the services it connects to;
  • send spam or malware, or build a competing service by scraping ours.

We may limit request rates, and suspend or close accounts that break these terms or put the service or others at risk.

Plans and payment#

  • The plans, their prices and limits are on the pricing page. Free has a monthly number of tool calls and a Drive size; Plus and Team have no monthly cap on tool calls, under the rate limits in Acceptable use.
  • Paid plans are sold by Polar (Polar Software Inc.), our merchant of record. Polar takes the payment, charges any sales tax or VAT, and sends receipts and invoices; its buyer terms apply to the purchase.
  • A subscription renews every month or year, as you chose, until you cancel it. Cancel any time in Settings → Billing → Manage: it stays on until the end of the period you paid for, and you aren't charged again.
  • A Team plan starts with 30 days free. You enter a card when you start the trial; cancel before it ends and you aren't charged.
  • A free trial turns into a paid subscription only with your consent. From 7 days before the trial ends, we ask the workspace's owners, by email and in the dashboard, whether to continue, with the price and the number of seats; you can also say yes any time during the trial. If nobody has said yes 3 days before the trial ends, we set the subscription to end with the trial and tell you, so you aren't charged; you can still continue until the trial ends.
  • A price increase for your subscription also needs your consent. We announce it at least 30 days before it takes effect; it first applies at your first renewal on or after that date, and from 30 days before that renewal we ask the owners, by email and in the dashboard, to accept it. If nobody has accepted it 3 days before the renewal, the subscription is set to end at the end of the period you've paid for, and you aren't charged the new price; you can still accept until then. If we couldn't ask at least 14 days before a renewal, that renewal stays at the old price. A lower price applies without asking.
  • We keep a record of each answer: who gave it, when, and the price and seats it was given for.
  • If you buy as a consumer (for example in the EU, the UK or Korea), you can withdraw within 14 days of your first payment for a subscription and get a full refund: cancel and tell us through the contact form or at support@0bridge.dev. This doesn't take away any longer right the law of your country gives you.
  • Apart from that, we don't refund part of a period you've started, except where the law requires it. If a charge looks wrong, tell us through the contact form or at support@0bridge.dev.
  • If a payment fails or a subscription ends, Plus goes back to Free's limits, and a team workspace stops taking new members and its files can be read but not changed. Nothing is deleted: Drive files over Free's size stay readable, and new files can be added once you're under it.
  • Deleting your account cancels the subscriptions of workspaces only you are in.

The software#

The 0b tool and the gateway source code are released under the license in their repository. These terms cover the hosted service at 0bridge.dev.

Availability and changes#

To the extent the law allows, 0bridge is provided "as is" and "as available", without warranties of any kind, express or implied. The service is in early development: features may change, and it may be interrupted or discontinued. We will give notice of material changes to these terms on this page before they take effect; continuing to use 0bridge after that means you accept them.

Liability#

To the fullest extent the law allows, we are not liable for indirect, incidental, special, consequential or punitive damages, or for lost data, profits or revenue, arising from your use of the service or of any connected service. Our total liability for any claim is limited to the amount you paid us for the service in the 12 months before the claim, or USD 50 if you paid nothing.

Nothing in these terms limits liability for intent, gross negligence, death or personal injury, or anything else the law doesn't allow to be limited, and nothing takes away rights a consumer has under the mandatory law of the country where they live.

Secrets you store#

Values you put in your 0bridge vault are encrypted on your devices before they reach us, with a key only your devices (and your passkey or recovery key) can open. We can't read them, so we can't recover them if you lose every device and your recovery key.

Governing law and disputes#

These terms are governed by the laws of the Republic of Korea. If you're a consumer, you also keep the protection of the mandatory consumer laws of the country where you live, and you can bring a claim in its courts. Otherwise, disputes go to the courts of Seoul, Korea. Tell us about a problem first through the contact form; most can be solved there.

Ending#

You can stop using 0bridge and delete your account at any time in the dashboard (Settings → Delete account). We may end or suspend access under the rules above. Sections on liability and acceptable use survive termination.
