Terms of Service

Last updated: August 21, 2026

These terms are a binding agreement between you and Arbiline. By creating an account or using the service you accept them. If you do not accept them, do not use Arbiline.

Please read sections 3, 11, 12 and 13 carefully: they describe the risks you take on, and they limit what we are liable for.

1. What Arbiline is, and what it is not

Arbiline is software. It shows market data, and it sends orders to the crypto exchanges where you hold your own accounts, using API credentials you provide.

Arbiline is not a broker, dealer, exchange, market maker, custodian, bank, payment institution, investment adviser, portfolio manager or fund. We do not hold, receive, control or have any power to withdraw your money or your crypto assets. Your assets stay in your own accounts at exchanges you chose, under agreements between you and those exchanges.

Nothing in the service creates a fiduciary, advisory or agency relationship between us. We do not manage your account, and we do not decide what you trade.

2. No financial advice

Everything the service displays — spreads, funding rates, history, calculations, alerts, suggested sizes and any other output — is general information produced automatically from market data. It is not investment advice, not a recommendation, not an offer or solicitation to buy or sell anything, and it takes no account of your circumstances, objectives or risk tolerance.

You are solely responsible for deciding whether any trade is suitable for you, and for obtaining your own financial, legal and tax advice before trading.

3. Risk

Trading crypto assets carries a substantial risk of loss, including the loss of everything you put in. Arbitrage strategies are not risk-free. Among other things, one side of a position can be liquidated or force-closed by an exchange while the other remains open, spreads can widen instead of converging, orders can fill partially or not at all, order books can be too thin for your size, funding rates can flip, exchanges can suspend deposits, withdrawals or trading, and assets can be delisted.

We do not guarantee profit, and no figure shown anywhere in the service or on our website is a promise of results. Simulated or demo results do not predict real trading outcomes, because a simulation cannot reproduce real fills, latency or market impact. Past performance means nothing about the future.

Only trade with funds you can afford to lose entirely.

4. Eligibility

You must be at least 18 years old and legally capable of entering into this agreement.

You must not use Arbiline if doing so would breach any law that applies to you, and it is your responsibility to check that. You confirm that you are not located in, resident in, or acting on behalf of anyone in a country or territory subject to comprehensive sanctions, and that you are not on any applicable sanctions or restricted-party list. We may refuse or terminate service where we believe this is not the case.

5. Your account

You sign in through Google. Keep control of that account: anything done through your Arbiline account is treated as done by you, and you are responsible for it. Tell us immediately at [email protected] if you believe your account has been accessed by someone else.

An account is for one person. Do not share access, resell it, or give your subscription benefits to anyone else. Where a plan includes a members-only group, your place in it is personal to you.

You must give us accurate information and keep it current.

6. Exchange connections and your instructions

When you connect an exchange, you authorise us to use those credentials to act on the instructions you give through the service: reading your balances, positions and orders, and placing, amending or cancelling orders.

Every order the service sends is your instruction, whether you press a button yourself or configure a feature to act on conditions you set. That includes automated trading, protective actions and any scheduled or conditional behaviour you switch on. You choose the parameters; the software follows them.

Create API credentials with trading permission only. Never enable withdrawal permission. You are responsible for complying with the terms, limits and rules of each exchange you use, including their rate limits, their position limits and their rules about automated trading and geographic access.

7. Automated features

Automated trading, position protection, alerts and similar features depend on continuous connectivity to exchanges and on their systems behaving normally. They can be delayed, can miss an event, or can fail entirely — for example during exchange downtime, network failure, API errors, rate limiting, maintenance on our side, or extreme market conditions.

These features reduce certain risks. They do not remove them, they are not a stop-loss guarantee, and they must not be relied on as the only protection for a position. You remain responsible for monitoring your own positions and for the consequences of any automated action taken on your instructions.

8. Market data

Market data comes from exchanges and other third-party sources. It can be delayed, incomplete, interrupted or wrong, and a spread displayed at one moment may not be executable at the next. We do not warrant the accuracy, completeness, timeliness or availability of any data, and we are not responsible for decisions you make based on it.

9. Availability and changes to the service

We aim to keep Arbiline available, but we do not promise any level of uptime. The service can be interrupted by maintenance, upgrades, failures of our providers, failures of exchanges, or events outside our control.

We may add, change, restrict or discontinue features, and we may impose or adjust limits on use. If we discontinue a paid feature entirely and that materially reduces what you bought, contact us and we will deal with it fairly.

10. Subscriptions, payment and refunds

Paid plans are prepaid for the term you choose. Payment is made in crypto through a third-party payment provider on its own checkout page; the provider’s own terms apply to that payment. Nothing renews automatically and we hold no payment method on file — when a term ends, access to paid features ends unless you buy another term.

Prices are shown in US dollars. You are responsible for any transaction or network fees charged by the payment provider or the blockchain, and for any taxes that apply to you. A payment is treated as complete when we receive confirmation from the payment provider; underpaid, late or misdirected transfers are handled case by case and may take time to resolve.

By purchasing, you ask us to give you access immediately. Where you are a consumer with a statutory right of withdrawal, you expressly consent to immediate performance and acknowledge that you lose that right once access begins. Subject to that, payments are non-refundable, including for unused time in a term, and we do not pro-rate.

We may change prices for future terms. A change never affects a term you have already paid for.

11. Acceptable use

You must not:

  • use the service for anything unlawful, or to breach the rules of an exchange;
  • attempt market manipulation, wash trading, spoofing, or any other abusive trading practice;
  • use the service to evade sanctions, anti-money-laundering rules, or an exchange’s compliance controls;
  • share, resell, sublicense or redistribute access, data or alerts from the service;
  • scrape, harvest or bulk-extract data beyond normal use of the interface, or use bots or scripts against our systems;
  • copy, modify, decompile, reverse engineer or attempt to derive the source code of the service;
  • probe, attack, overload or interfere with our systems or security, or circumvent access controls, plan limits or rate limits;
  • impersonate anyone, or misrepresent your identity or eligibility.

We may investigate suspected breaches and take the steps in section 14.

12. Disclaimer of warranties

To the fullest extent permitted by law, the service is provided "as is" and "as available", without warranty of any kind. We disclaim all implied warranties, including merchantability, fitness for a particular purpose, non-infringement, accuracy, and any warranty arising from course of dealing or usage of trade.

We do not warrant that the service will be uninterrupted, timely, secure or error-free, that defects will be corrected, that data will be accurate, or that the service will achieve any particular result.

13. Limitation of liability

To the fullest extent permitted by law, we are not liable for any trading losses, lost profits, lost opportunities, lost or unexecuted trades, liquidations, funding costs, slippage, loss of data, or any indirect, incidental, special, consequential, exemplary or punitive damages, however caused and under any theory of liability, even if we were advised that such damages were possible.

We are not liable for the acts, omissions, outages, errors, insolvency, security failures or policy changes of any third party, including exchanges, the payment provider, Telegram, connectivity providers and market-data sources.

Where we are liable despite the above, our total aggregate liability for all claims arising out of or relating to the service is limited to the amount you actually paid us in the three months immediately before the event giving rise to the claim.

Nothing in these terms excludes or limits liability that cannot be excluded or limited by law, including liability for death or personal injury caused by negligence, or for fraud. If you are a consumer, these terms do not affect your mandatory statutory rights.

14. Suspension and termination

You may stop using the service at any time, and you can ask us to delete your account as described in our Privacy Policy.

We may suspend or terminate your access, with or without notice, if you breach these terms, if we are required to by law, if we reasonably believe your use creates legal, security or financial risk to us, to other users or to an exchange, or if your payment fails or is reversed. Where the breach is minor and fixable, we will normally tell you first and give you a chance to fix it.

If we terminate for breach, no refund is due. Termination does not affect any right or obligation that has already arisen, and sections 2, 3, 8, 12, 13, 15 and 17 survive.

15. Indemnity

You agree to indemnify and hold us harmless from any claim, demand, loss, liability, cost or expense, including reasonable legal fees, arising out of your use of the service, your trading activity, your breach of these terms, your breach of an exchange’s terms, or your violation of any law or the rights of anyone else.

16. Intellectual property

The service, including its software, interface, design, text and the data presentation we produce, belongs to us or our licensors. We grant you a limited, personal, non-exclusive, non-transferable, revocable right to use it while your account is in good standing, for your own trading and nothing else. All other rights are reserved.

Your own content and trading data remain yours. Feedback you send us may be used freely and without obligation to you.

17. Events outside our control

We are not liable for any failure or delay caused by events beyond our reasonable control, including exchange or infrastructure outages, network or internet failures, denial-of-service attacks, blockchain congestion or forks, extreme market volatility or trading halts, acts of government, changes in law, sanctions, natural disasters, war or civil unrest.

18. Changes to these terms

We may update these terms as the service and the law change. The date at the top shows the current version. If a change materially affects your rights or obligations, we will notify you in the application or by email before it takes effect. Continuing to use the service after that means you accept the updated terms; if you do not accept them, stop using the service.

19. Disputes and governing law

If something goes wrong, contact us first at [email protected]. Most problems are resolved quickly, and you agree to try that route in good faith for 30 days before starting formal proceedings.

These terms, and any dispute arising out of them or the service, are governed by the law of the country in which Arbiline is established, and the courts of that country have exclusive jurisdiction. If you are a consumer, this does not deprive you of the protection of mandatory rules of the country where you live, or of the right to bring proceedings there where the law gives you that right.

20. General

These terms, together with the Privacy Policy, are the entire agreement between us about the service, and they replace anything said or written before.

If any provision is held unenforceable, it is limited or removed to the minimum extent necessary and the rest stays in force. If we do not enforce a right, we do not waive it. You may not transfer your rights under these terms; we may transfer ours to a successor in connection with a merger, acquisition or sale of assets, without reducing your rights.

Notices to you may be sent to the email on your account or shown in the application; notices to us go to [email protected]. These terms are written in English, and the English version prevails over any translation.
