1. Who we are
Ant0 is run by BLACKBIRD SECURE BROWSING LTD · Company number 13404707 · Registered address: 41 Devonshire Street, Ground Floor, London, United Kingdom, W1G 7AJ (“we”, “us”). These terms are an agreement between you and us.
They cover the Ant0 desktop app, the Ant0 Browser engine it installs, the background service and
local API, the account service at api.ant0.link, and this website (together, the “Service”).
By creating an account or installing the app, you accept these terms. If you use the Service for a company, you confirm you may bind it, and “you” means that company.
You must be 18 or older to use the Service.
2. What the Service does
Ant0 runs separate browser profiles on your computer. Each has its own browser identity, cookies and proxy, and you manage them from one list or through a local API. We don’t provide proxies, accounts on other websites or any content. What you do inside a profile is your activity on the websites you visit, under their terms.
3. Your account
You sign in with an email address and password, and you can add two-factor authentication. Keep your sign-in details private; you are responsible for what happens under your account.
The Free plan is limited to one free workspace per computer. Each paid seat covers two computers or browsers signed in at the same time.
Account support: support@ant0.link. Security reports: security@ant0.link.
4. Acceptable use
You must follow the Acceptable use policy, which is part of these terms.
5. Plans, prices and payment
The Free plan costs nothing. Paid plans are bought from Billing in your account.
- Prices are in US dollars and exclude tax. You pay any tax due where you are.
- Invoices are fixed in US dollars. You pay in cryptocurrency: Bitcoin through our BTCPay Server
at
pay.ant0.link, or other coins through NOWPayments. There is no card, PayPal or bank transfer. - A payment link is valid for a limited time. Network fees and exchange-rate changes are yours. An underpayment does not start your plan. A payment that arrives too late, or a second payment for the same invoice, becomes account credit at the invoice amount. We can’t return coin paid above the invoice amount.
- Your plan starts when the payment is confirmed. For Bitcoin this depends on the network.
- Nothing is charged automatically. Seven days before a paid period ends, we email a renewal invoice and remind you the day before. If it isn’t paid when the period ends, you have seven more days. After that the workspace moves to the Free plan: you choose which profiles stay usable within the Free limit, and the rest stay listed and exportable but can’t start.
- Cancelling ends your paid plan straight away. Unused prepaid time becomes account credit. A computer that is offline at that moment can keep working for up to its last plan check (24 hours) plus the three-day offline allowance.
See the Refund policy for credit and refunds.
6. Your right to cancel within 14 days
If you are a consumer in the UK, you normally have 14 days to cancel a purchase of digital content or services. Because we start your plan as soon as your payment is confirmed, to buy you must tick “Start immediately (no 14-day cancellation)” at checkout. By ticking it you ask us to begin straight away and you agree that your plan starts as soon as your payment is confirmed and that you then lose the right to cancel within 14 days. The box is not ticked for you, and you cannot pay without ticking it. We record your choice with the invoice and confirm it in your receipt email. This does not affect your other legal rights, for example if the Service is faulty.
7. Software licence (EULA)
We give you a personal, non-exclusive, non-transferable licence to install and use the Ant0 software (the desktop app, the background service and the Ant0 Browser engine) within the limits of your plan while these terms apply.
You may not sell, rent, sublicense or share the software, or remove, bypass or tamper with its plan, sign-in or integrity checks. You may not reverse-engineer or decompile it except where the law allows it. The engine is based on Chromium and other open-source software; each of those parts stays under its own licence, listed in the app under Settings → About → Licences, and nothing in these terms limits your rights under those licences.
8. Your data
Your profile names, notes, cookies, browser storage and proxy details stay on your computer unless you turn on workspace sync, which uploads them encrypted. What the Service sends and stores, and for how long, is in the Privacy policy. If you use a team workspace, the Data processing terms apply to the personal data of your team members. We do not sell personal data.
9. Availability and changes
We work to keep the Service available, but we don’t promise it will always be. If the account service can’t be reached, existing profiles keep starting for three days; you can’t create new ones until the app reconnects. We may change or remove features.
10. Our liability to you
The Service is provided “as is”. We don’t promise that a website will treat a profile in any particular way, that a proxy will work, or that the Service suits a particular purpose.
Our total liability to you for all claims is limited to the fees you paid us in the 3 months before the claim, or £10 if you are on the Free plan. We are not liable for indirect or consequential loss, lost profits or data, or for actions other websites take against your accounts.
Nothing in these terms limits liability for death or personal injury caused by our negligence, for fraud, or for anything else the law does not allow us to limit. If you are a consumer, your statutory rights are not affected.
11. Your responsibility to us
If someone makes a claim against us because you used the Service unlawfully or broke the Acceptable use policy, you will cover our reasonable losses and costs from that claim.
12. Suspension and ending
You can stop using the Service at any time.
We may suspend or close an account that breaks these terms or the Acceptable use policy, or where the law requires it. How suspension works is in the Acceptable use policy. When your account ends, your licence to use the software ends. Sections 7 (restrictions), 8, 10, 11 and 13 continue to apply.
13. General
- Law and courts: these terms are governed by the law of England and Wales, and the courts of England and Wales decide disputes. If you are a consumer, you keep the protection of the mandatory laws of the country you live in, and you can bring a claim there.
- Changes: we announce material changes by email and on this page at least 30 days before they apply. If you keep using the Service after that, the new terms apply.
- Whole agreement: these terms, the policies they link to and your plan are the whole agreement between us. If one part can’t be enforced, the rest still applies. Only you and we can enforce these terms. We may transfer our rights to a company that takes over the Service; we’ll tell you if we do.
- Events outside our control: we are not responsible for delays or failures caused by events we can’t reasonably control.
- Complaints: email support@ant0.link first. We aim to reply within 14 days.
