Terms of Service & Risk Disclaimer

Terms of Service: Version 1.3 — Effective 14 October 2026 · Risk Disclaimer: Version 1.1 — Effective 8 September 2026
Terms of Service Privacy Policy Risk Disclaimer
OPERATED BY The SixOne8 application and website are owned and operated by Marlstone Group Ltd (company number 17403937), registered in England and Wales. Registered address: 71-75 Shelton Street, Covent Garden, London WC2H 9JQ, United Kingdom · Support: support@sixone8.app

These are the same Terms of Service and Risk Disclaimer the app asks you to accept at sign-up. See also the Privacy Policy.

Terms of Service

These Terms of Service ("Terms") are an agreement between you and Marlstone Group Ltd, a company registered in England and Wales (company number 17403937) ("we", "us", "the operator"), the operator of this application ("the Service"). By creating an account or accepting these Terms in the app, you agree to them. If you do not agree, do not use the Service.

1. What the Service is — and is not

1.1 The Service is a rule-based market-monitoring and historical-analysis software tool. You define market conditions ("strategies") — directly, or, on qualifying plans, by asking the Service to translate a plain-language description into rules — and the Service monitors market data against those conditions and notifies you when they occur. It also provides charts, historical analysis, and — on qualifying plans — the ability to test a strategy against historical data.

1.2 Some features generate or modify strategy rules at your request. The AI strategy builder translates your description into conditions and may add conditions needed to express it; the AI review describes what a definition will and will not catch. Refine generates candidate variations of a strategy you already built — varying, replacing, or removing only the conditions you have opened to change — tests each candidate against historical data, and ranks the candidates by a disclosed scoring formula computed from those historical results. A rank or score states only how a candidate scored under that formula, over that history, with your selected settings. It is not a determination by us that the candidate is suitable, advisable, or likely to be profitable, and nothing is adopted into your strategies unless you choose to adopt it.

1.3 The Service is not a financial adviser, broker, dealer, or portfolio manager, and we do not publish discretionary or operator-authored trading signals. Alerts are mechanical notifications that the conditions configured on your account have been detected; they are not instructions from us to enter, exit, or modify any transaction. The Service does not execute trades, hold funds, or access any trading or brokerage account. No feature of the Service — including alerts, rankings, match percentages, templates, backtests, entry checks, AI-generated or AI-reviewed strategies, and Refine candidates — is investment advice, a recommendation, or a solicitation to buy, sell, or hold any instrument. The Risk Disclaimer, which you accept separately, forms part of these Terms.

1.4 Every trading decision you make, and every consequence of it, is yours alone.

2. Eligibility and accounts

2.1 You must be at least 18 years old and legally able to enter into this agreement.

2.2 You sign in with your Apple or Google account, or with an email address and a password you choose. You are responsible for keeping your sign-in details and your device secure; activity on your account is treated as yours.

2.3 One account per person. Creating additional or replacement accounts to obtain promotional benefits more than once, to evade a suspension, or to circumvent plan limits is a breach of these Terms (see 4.6 and 9).

2.4 At sign-up you select your country from the supported list. It determines the prices you are shown and which regional terms apply to you. If the billing country reported by your app store differs, the store-reported country will be used instead. A billing address you give at the web checkout is used for that purchase only and does not change your registered country.

2.5 Instrument availability varies by country. In countries where a class of instruments cannot lawfully or appropriately be offered to residents, the Service shows and monitors only the permitted classes. In particular, accounts registered in India or the Philippines have access to cryptocurrency instruments only, and no foreign-exchange or precious-metals instruments. Country availability is a property of the Service in your country, not of your plan: no subscription or purchase changes it. If your registered country changes (see 2.4), instrument availability follows the new country, and monitoring configured against instruments the new country excludes is suspended, not deleted.

3. Subscriptions, billing, and cancellation

3.1 Paid plans are sold as auto-renewing subscriptions through two channels: in the apps, through the Apple App Store or Google Play ("the stores"); and on our website, through Stripe, which sells them as the merchant of record under its Managed Payments service ("the web checkout"). In either case your billing relationship for payment is with the store or with Stripe, under its terms, and we never receive or store your card details. A web purchase appears on your card statement as "LINK.COM*" followed by our name, and on Stripe's receipts as sold through Link, Stripe's payment service.

3.2 The price shown at the moment of purchase — on the store's purchase sheet, or on the web checkout page — is the price you pay, and includes any tax the store or Stripe applies. Prices displayed elsewhere in the Service are indicative; the figure at purchase governs.

3.3 Subscriptions renew automatically until cancelled. To cancel a store subscription, use your App Store or Google Play subscription settings; we cannot cancel a store subscription for you. To cancel a web subscription, use "Manage subscription" on your account page in the web app, which opens Stripe's billing portal, or your Link account. Cancelling stops future renewal; you keep your plan's features until the end of the period you have paid for.

3.4 Upgrades and downgrades are made where you subscribed: in the store for a store subscription, and in the billing portal for a web subscription. Upgrades generally take effect immediately, with a pro-rated charge for the rest of the current period; downgrades, and a change from annual to monthly billing, generally take effect at your next renewal. The exact charge for a plan change is shown at the time you make it.

3.5 One subscription per account. A subscription bought through one channel cannot be changed, cancelled, or refunded through the other. The Service will not sell you a second subscription while one that still renews exists on your account, through either channel. To move from the stores to the web checkout or back, turn off renewal on the existing subscription first; the new one may then begin, and the old one runs to the end of its paid period. If two renewing subscriptions nonetheless arise on one account — for example from purchases made at the same moment — we keep the earlier one, stop the later one renewing, and refund what was paid for it.

3.6 Refunds for store purchases are handled by the stores under their policies. Refunds for web purchases are handled by Stripe, as merchant of record, under its terms, and may also be issued by us at our discretion; in either case, contact support@sixone8.app first. Where a subscription is refunded in full, access under it ends when the refund takes effect. Nothing in this clause limits any non-excludable statutory right to a remedy from us (see 3.7, 10, and the Regional Terms).

3.7 Web purchases: your right to change your mind. If you are a consumer in the United Kingdom, or in another country whose law gives you an equivalent cooling-off right, you may cancel a web purchase within 14 days of making it and receive a refund. Because you ask us to start providing the Service immediately, and agree to that when you subscribe, the refund is reduced by a proportionate amount for the part of the period you have already had — unless the 14 days fall within a free trial, in which case nothing has been charged. To exercise this right, email support@sixone8.app within the 14 days, or cancel in the billing portal and tell us you want a refund. Store purchases are governed by the store's own refund rules instead.

3.8 If a renewal payment fails, the store or Stripe may retry for a grace period during which your plan continues; if payment is not recovered, your plan lapses to the free tier.

3.9 When your plan lapses or you downgrade, content that exceeds the new plan's limits (for example, strategies over the free tier's cap, or features the new plan does not include) is suspended, not deleted. It reactivates automatically if you return to a qualifying plan.

3.10 Free trials. A paid plan may open with a free trial. In the stores, the trial is an introductory offer that the store offers and administers: whether you are eligible is decided by the store (typically once per store account), and its length and the price that follows it are shown on the store's purchase sheet. On the web checkout, the trial is seven days, is offered once per person — across every account you create and both channels — and is shown on the checkout page when it applies. A free trial converts into a paid, auto-renewing subscription at the end of the trial unless you cancel before it ends — in your store subscription settings, or in the billing portal for a web subscription. Cancelling during the trial keeps the plan's features until the trial ends, and nothing is charged. A free trial is different from a promotional code (clause 4): a promotional grant never converts into a paid subscription.

4. Promotional codes

4.1 We may issue promotional codes granting temporary access to a paid tier. A code is redeemable once per person, has whatever duration and conditions accompany it, and has no cash value.

4.2 To enforce one-per-person fairness, we retain a record of the sign-in identity and email that redeemed each code, and this record survives account deletion (see the Privacy Policy).

4.3 We may deactivate a code that has been leaked, abused, or issued in error; access already granted under a redemption is not withdrawn by deactivation.

4.4 A promotional grant sits alongside, and never reduces, any paid subscription you hold: your effective plan is always the highest tier you are entitled to at the time.

4.5 Promotional grants expire at the end of their stated period without charge; they are not auto-renewing and do not convert into paid subscriptions. They are not free trials (see 3.10).

4.6 Obtaining or attempting to obtain promotional benefits repeatedly — including by deleting and re-creating accounts or by using multiple sign-in identities — is a material breach.

5. The free tier

A free plan is provided with limited instruments, timeframes, and features. We may adjust what the free tier includes. The free tier is provided "as available" without any service commitment beyond the non-excludable rights described in clause 10.

6. Market data, alerts, and availability

6.1 Market data is sourced from third parties. It may be delayed, incomplete, or erroneous, and instruments may be added, suspended, or discontinued. If an instrument is discontinued, monitoring against it stops; your configurations are preserved.

6.2 Alert delivery is best-effort. Push notifications depend on Apple's and Google's delivery services, your device settings, and network conditions, and may be delayed, deduplicated, or not delivered. A daily delivery cap applies to every account. You must not rely on the Service as your only means of monitoring any position or market, and you must never rely on an alert as the sole mechanism for managing a stop-loss, an open position, a risk limit, or any other time-critical financial action.

6.3 We may suspend or modify the Service for maintenance, security, or legal reasons. We aim for continuity but do not promise uninterrupted availability, except to the extent a Regional Term or non-excludable law provides otherwise.

7. Your content and our licence to process it

7.1 You retain your rights in the strategy configurations, watchlists, and settings you create. You grant us a licence to host, process, evaluate, and back up that content in order to run the Service — including evaluating your strategies against market data on our servers, generating and testing variations of them when you ask us to, and sending you the resulting notifications. The licence ends when the content is deleted, except for (a) copies in backups until the backup cycle expires, (b) records we must keep for legal or security purposes (see the Privacy Policy), and (c) aggregated, de-identified information under 7.2.

7.2 We may use aggregated, de-identified information about Service usage to operate and improve the Service. We will not attempt to re-identify it. We do not publish or sell your individual strategies.

8. Acceptable use

You must not: (a) use the Service to provide signals, alerts, or advice to third parties, commercially or otherwise; (b) resell, scrape, or bulk-extract market data or Service output; (c) reverse engineer, probe, or interfere with the Service, its rate limits, or its security controls; (d) misrepresent the Service's output as advice or as your own regulated service; (e) use the Service where or while prohibited by applicable law.

9. Suspension and termination by us

We may suspend or terminate your account for material breach of these Terms (including 2.3, 4.6, and 8), for legal or security reasons, or if the Service is discontinued. Where practicable we will give notice. If we terminate for a reason other than your breach while you are inside a period you have paid for, you are entitled to any refund or other remedy that applicable law requires for the unused part of that period — provided by us for a web subscription, and with our support for the store's process for a store subscription. Termination does not affect the store's or Stripe's handling of any subscription refund, nor rights and obligations that by their nature survive.

10. Warranties and liability

10.1 Nothing in these Terms excludes, restricts, or modifies any right or remedy you have under law that cannot be excluded, restricted, or modified — including your rights as a consumer under the Australian Consumer Law, the UK Consumer Rights Act 2015, applicable Canadian provincial consumer protection legislation, the Singapore Consumer Protection (Fair Trading) Act, analogous US state laws, UAE Federal Law No. 15 of 2020 on Consumer Protection, the Indian Consumer Protection Act 2019, Philippine consumer protection law (including the Consumer Act, Republic Act No. 7394, and, to the extent applicable to the Service, Republic Act No. 11765), and applicable Pakistani consumer protection legislation. The Regional Terms in clause 14 apply to you in addition.

10.2 Subject to 10.1, the Service is provided "as is" and "as available", and we exclude all other warranties, conditions, and guarantees, express or implied.

10.3 Subject to 10.1, we are not liable for: (a) trading losses of any kind, including losses on any position you take or fail to take, whether or not connected to an alert, a delayed alert, a missed alert, a backtest, or any other feature; (b) loss of profit, revenue, opportunity, or data; or (c) indirect or consequential loss.

10.4 Subject to 10.1, and only to the extent the law that applies to you permits, our total aggregate liability arising out of or in connection with the Service in any 12-month period is limited to the greater of (a) the amounts you paid for the Service in that period and (b) USD 50 (or local equivalent).

10.5 Every limitation and exclusion in this clause 10 applies only to the extent permitted by the law that applies to you, and never reduces a statutory right to a refund, a repeat performance, a price reduction, or any other remedy that cannot lawfully be limited. Any country-specific exception is stated in the Regional Terms.

11. Changes to the Service and to these Terms

11.1 We may improve or change Service features. We will not materially reduce the core functionality of a paid plan during a billing period you have already paid for, except where reasonably necessary for legal, security, fraud-prevention, or technical reasons outside our reasonable control (including a market-data provider or a store withdrawing something). Where such a reduction cannot reasonably be avoided, we will provide any refund, credit, or other remedy that applicable law requires and, where appropriate and supported by the store, a proportionate remedy for the affected part of the period. You may also cancel renewal at any time.

11.2 We may update these Terms. When we publish a new version, you will be asked to accept it in the app before continuing; the version you accepted, and when, is recorded. A change that materially reduces your rights or increases your obligations will be published with an effective date at least 30 days after it is announced in the app, except where the change is required by law or needed for security, and no change applies retroactively to anything that happened before its effective date. If you do not accept a new version, you may stop using the Service and cancel renewal (see 3.3); any mandatory statutory right you have, including to a remedy for a paid period you can no longer use because you declined the new version, is preserved.

12. Account deletion

12.1 You may delete your account in the app at any time. Deletion is final: signing in again later creates a new account and does not restore the old one.

12.2 Deleting your account does not cancel a store subscription, and only the store can cancel or refund one: billing continues until you cancel it in your store subscription settings, and deletion removes your access even though the subscription remains active. A web subscription is different: when you delete your account we cancel it for you at the end of the period you have paid for, nothing further is charged, and nothing already paid is refunded by the deletion itself (see 3.6 and 3.7 for refunds). If a subscription of either kind is still active when you ask to delete your account, the app stops, tells you which of these applies, and proceeds only once you confirm. A still-active store purchase can be moved to a replacement account only by our support, on request and with verification.

12.3 What is deleted and what is retained after deletion is described in the Privacy Policy.

13. General

These Terms, the Privacy Policy, and the Risk Disclaimer are the entire agreement between us for the Service. If a clause is unenforceable, the remainder stands. A failure to enforce is not a waiver. You may not assign these Terms; we may assign them as part of a business transfer with notice to you. The Service, these Terms, the Privacy Policy, the Risk Disclaimer, and our support are provided in English; if we ever provide a translation of any of them, it is for convenience only and the English text governs. The Service is offered in Canada outside the Province of Quebec only: it is not currently offered to consumers in Quebec, and we do not provide it in French.

14. Governing law, disputes, and Regional Terms

14.1 If you reside in the United Kingdom: these Terms are governed by the laws of England and Wales, and you may bring proceedings in your local courts. Nothing affects your rights under the Consumer Rights Act 2015. The operator is not authorised or regulated by the Financial Conduct Authority, and the Service does not provide regulated investment advice.

14.2 If you reside in Australia: these Terms are governed by the laws of New South Wales, Australia. Our services come with guarantees that cannot be excluded under the Australian Consumer Law. Nothing in these Terms excludes, restricts, or modifies a consumer guarantee, right, or remedy that cannot lawfully be excluded, restricted, or modified under the Australian Consumer Law, and every limitation elsewhere in these Terms applies only to the extent permitted by that law.

14.3 If you reside in Canada: these Terms are governed by the laws of the Province of Ontario and the federal laws of Canada applicable there, without depriving you of the protection of mandatory consumer protection rules of your province of residence. The Service is not currently offered to consumers in Quebec (see clause 13).

14.4 If you reside in Singapore: these Terms are governed by the laws of Singapore. Nothing affects your rights under the Consumer Protection (Fair Trading) Act 2003.

14.5 If you reside in the United States: these Terms are governed by the laws of your state of residence. Nothing in these Terms waives rights that your state's law does not permit to be waived. Disputes may be brought in the courts of your state of residence, including small claims court where eligible.

14.6 If you reside in the United Arab Emirates: these Terms are governed by the federal laws of the United Arab Emirates as applied by the onshore courts, without depriving you of the protection of Federal Law No. 15 of 2020 on Consumer Protection or, if you are in a financial free zone, of the mandatory rules that apply there. The operator is not licensed or regulated by the UAE Securities and Commodities Authority, the Dubai Financial Services Authority, the ADGM Financial Services Regulatory Authority, or any other UAE financial regulator. The operator does not intend to provide a regulated Financial Consultancy or other regulated advisory service under applicable UAE financial-services law, and does not itself issue buy, sell, or hold recommendations.

14.7 If you reside in India: these Terms are governed by the laws of India, without depriving you of the protection of the Consumer Protection Act 2019. The operator is not registered with the Securities and Exchange Board of India in any capacity (including as a research analyst or investment adviser) and is not authorised by the Reserve Bank of India. The Service offers accounts registered in India cryptocurrency instruments only (see 2.5) and does not offer, promote, or facilitate foreign-exchange trading.

14.8 If you reside in the Philippines: these Terms are governed by the laws of the Republic of the Philippines, without depriving you of the protection of Philippine consumer protection law, including the Consumer Act (Republic Act No. 7394) and, to the extent applicable to the Service, the Financial Products and Services Consumer Protection Act (Republic Act No. 11765). The operator is not registered with the Philippine Securities and Exchange Commission in any capacity. The Service offers accounts registered in the Philippines cryptocurrency instruments only (see 2.5) and does not offer, promote, or facilitate foreign-exchange trading.

14.9 If you reside in Pakistan: these Terms are governed by the laws of the Islamic Republic of Pakistan, without depriving you of the protection of applicable consumer protection legislation of your province. The operator is not licensed by the Securities and Exchange Commission of Pakistan or by the Pakistan Virtual Assets Regulatory Authority, and the Service does not provide securities, futures, or virtual-asset advisory services.

14.10 We do not require arbitration, and nothing in these Terms prevents you from using your local small-claims process or complaining to your local consumer or data-protection authority.

Risk Disclaimer

Read this carefully. By accepting it you acknowledge each statement below.

1. This Service does not provide financial advice. It is a software tool that monitors market conditions configured on your account and notifies you when those conditions occur. Some conditions are written by you directly; some are generated or modified by automated features (the AI strategy builder, the AI review, and Refine) at your request and within the limits you set. Either way, alerts, match percentages, rankings, scores, templates, backtests, entry checks, and generated or refined strategies are information produced by a mechanical process from configured criteria — they are not investment advice, trading advice, a recommendation, an opinion on the merits of any transaction, or a solicitation to buy, sell, or hold any instrument.

2. General information only. Nothing in the Service takes into account your objectives, financial situation, or needs. Before acting on anything you see in the Service, consider its appropriateness for your circumstances and consider seeking advice from an independent, licensed financial adviser in your jurisdiction.

3. We are not a regulated firm. The operator of this Service is not licensed, authorised, or regulated as an investment adviser, financial adviser, research analyst, broker, or dealer by any regulator, including the FCA (UK), ASIC (Australia), MAS (Singapore), the SEC, CFTC, or any US state regulator, any Canadian securities regulator, the UAE Securities and Commodities Authority, the Dubai Financial Services Authority, the ADGM Financial Services Regulatory Authority, SEBI or the Reserve Bank of India, the Securities and Exchange Commission of the Philippines, the Securities and Exchange Commission of Pakistan, or the Pakistan Virtual Assets Regulatory Authority. The operator is not registered as an investment adviser or research analyst in any jurisdiction. No client, advisory, or fiduciary relationship is created by your use of the Service.

4. Trading is high risk. Foreign exchange, precious metals, and cryptocurrency markets are volatile. Leveraged trading can result in losses that exceed your deposits. Cryptocurrency markets can be illiquid, unregulated in some jurisdictions, and subject to abrupt loss of value. Never trade with money you cannot afford to lose.

5. Hypothetical and historical results have inherent limitations. Backtests and historical match statistics are produced with the benefit of hindsight against recorded data. They do not reflect actual trading, do not fully account for spreads, slippage, liquidity, fees, or market impact, and no representation is being made that any account will or is likely to achieve results similar to those shown. Past performance, whether real or simulated, is not indicative of future results.

6. Alerts can be late, wrong, or missing. Market data can be delayed or erroneous; delivery of notifications depends on third parties and your device, and is not guaranteed. Do not rely on this Service as your only means of monitoring any position or market, and never rely on an alert as the sole mechanism for managing a stop-loss, an open position, a risk limit, or any other time-critical financial action.

7. Your decisions are your own. You are solely responsible for every trading decision and its consequences. To the maximum extent permitted by law — and without limiting any right that cannot be excluded — the operator accepts no liability for trading losses.

8. Crypto products are unregulated in some jurisdictions and can be highly risky. There may be no regulatory recourse for any loss from transactions in crypto assets. In some countries the Service offers cryptocurrency instruments only (see the Terms of Service); this reflects local law on other instrument classes and is not a statement that crypto assets are safe, endorsed, or suitable for you.

9. Automated and generated strategy outputs. Automated features may translate your instructions into strategy rules and, where you permit it, add, remove, replace, or alter conditions to produce candidate strategy configurations. Refine may generate and test many candidate configurations and rank them by disclosed historical metrics. Generated configurations have not been independently validated by the operator and may contain inappropriate, unintended, or logically flawed conditions. A higher historical score does not mean a configuration is safer, suitable for you, or more likely to perform well in future markets. Testing many variations against one history increases the risk of data-mining and overfitting: a configuration selected because it scored best among many historical variants may perform materially worse in live markets.
