Welcome to GammaFlip.io (the "Service"). These Terms and Conditions (the "Terms") govern your access to and use of the Service and form a binding agreement between you (the "User", "you") and:
By creating an account, paying for a subscription, or otherwise using the Service, you confirm that you have read, understood and accepted these Terms and our Privacy Policy. If you do not agree, do not use the Service.
GammaFlip.io is a data analytics and visualisation tool for options markets, covering both cryptocurrency and traditional-finance (US indices, ETFs and equities) instruments. We provide market data, charts and analytics for informational and educational purposes only.
To use the Service you must:
We may refuse, suspend or terminate access to anyone who does not meet these requirements.
To access most features you must create an Account. You agree that:
We offer Monthly and Annual subscription plans for card payments, and prepaid Quarterly and Annual terms for crypto payments, in addition to a free tier and a time-limited free trial. The price and feature set of each plan are shown on the pricing page at the time of purchase and form part of these Terms by reference.
Card payments are processed by Paddle.com Market Ltd, who acts as our Merchant of Record. Paddle is responsible for collecting payment, charging applicable VAT and issuing invoices. A small number of legacy subscriptions are still serviced by Lemon Squeezy LLC under the same Merchant-of-Record model; these will be transitioned to Paddle and the relationship with Lemon Squeezy will then end.
Crypto payments are processed through NOWPayments Ltd, a crypto payment gateway that provides the hosted checkout and settlement only; NOWPayments is not the merchant of record. For crypto payments the seller and merchant of record is the Company. A crypto payment is a one-off charge for a fixed prepaid term (see Section 6.3) and is not a stored-card recurring payment.
Card subscriptions renew automatically at the end of each billing period (monthly or annually) at the then-current rate, unless you cancel before the renewal date. We will notify you of any price changes by email at least 30 days before they take effect; you may cancel before the new price applies.
Crypto subscriptions do not auto-renew. A crypto payment buys a fixed prepaid term (Quarterly or Annual); at the end of the term your Account automatically reverts to the free tier unless you make a new crypto payment. If you renew a crypto term before it expires, the new term is added to the end of your current term.
For card payments, prices shown may be exclusive of VAT; Paddle, as Merchant of Record, determines and adds the applicable tax based on your billing country at checkout. For crypto payments, the price shown is the total amount payable and is inclusive of any VAT we are required to account for, which we account for under the VAT rules of Portugal, our country of establishment.
This Section sets out the statutory minimum; for a fuller, plain-language description of how cancellations and refunds work in practice, see our Refund & Cancellation Policy.
When you create an Account, you receive a 3-day free trial of premium features without providing a payment method. The trial does not auto-convert to a paid Subscription; at the end of 3 days your Account is automatically downgraded to the free tier. As no payment is taken during the trial, no refund question arises.
If you are a consumer in the European Union, under Directive 2011/83/EU and Portuguese Decreto-Lei n.º 24/2014 you have the right to withdraw from your paid Subscription within 14 days of the start of the contract, without giving any reason.
The Service is a digital service that begins to be supplied as soon as your Subscription is activated. By starting to use the Service before the end of the 14-day withdrawal period, you expressly request that performance begins immediately and you acknowledge that, under Art. 17(1)(m) of Decreto-Lei n.º 24/2014, your statutory right of withdrawal may be lost once the Service has been fully performed with your prior consent.
Independently of the statutory right of withdrawal in Section 7.2, we voluntarily offer a 14-day money-back guarantee on your first paid Subscription. If you are not satisfied for any reason, contact support@gammaflip.io within 14 days of your first paid charge and we will refund the full amount, regardless of whether you have started to use the Service. This guarantee applies only to your first paid Subscription and not to renewals.
Renewal charges are not automatically refundable. However, if you notice an unexpected auto-renewal charge and contact us within 48 hours of the charge, and you have not used premium features since the renewal, we will normally refund the renewal in full as a goodwill gesture. After 48 hours, refunds on renewals are at our sole discretion (for example, prolonged service unavailability, duplicate billing, or manifest billing error).
The money-back guarantee and goodwill refunds do not apply where (a) you initiate a chargeback without first contacting us, (b) our anti-fraud system identifies repeat subscribe-and-refund abuse across multiple Accounts, or (c) the Account is terminated by us under Section 10 for breach of these Terms.
Crypto payments buy a fixed prepaid term and do not auto-renew, so the renewal provisions in Section 7.4 do not apply to them. The 14-day money-back guarantee in Section 7.3 applies to your first crypto purchase on the same basis as a card payment. Because crypto transactions are irreversible, any refund is made by sending the equivalent value of your payment — in a stablecoin or the original cryptocurrency, converted at the exchange rate at the time of the refund — to a wallet address you provide. We are not responsible for value lost to exchange-rate movement between your payment and the refund.
You may cancel your Subscription at any time:
Cancellation stops the next automatic renewal. You will continue to have premium access until the end of the period you have already paid for; no partial refund is issued for the unused portion (subject to Section 7).
Crypto terms are prepaid and do not auto-renew, so there is nothing to cancel: access continues until the end of the term you have paid for and then reverts to the free tier.
When using the Service you agree not to:
We may suspend or terminate your Account, with or without notice, if:
On termination, your right to use the Service ceases immediately. Sections that by their nature should survive termination (Intellectual Property, Disclaimers, Limitation of Liability, Governing Law) will continue to apply.
All content, features and functionality of the Service — including charts, data visualisations, lesson materials, code, design, trademarks and logos — are owned by the Company or its licensors and are protected by international copyright, trademark and other intellectual property laws.
Subject to your compliance with these Terms, we grant you a limited, personal, non-exclusive, non-transferable, revocable licence to access and use the Service for your own non-commercial purposes. All other rights are reserved.
The Service incorporates market data sourced from third parties — cryptocurrency exchanges (Deribit, Bybit, OKX and others) and US options and market-data providers for traditional-finance instruments. We do not guarantee the accuracy, completeness or timeliness of this data. The Service may be temporarily unavailable or display stale data if an upstream provider experiences an outage.
The Service is provided "AS IS" and "AS AVAILABLE", without warranties of any kind, whether express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy or non-infringement, except for warranties that cannot be excluded under mandatory consumer-protection law.
We do not warrant that the Service will be uninterrupted, error-free, secure, or that any defects will be corrected.
To the maximum extent permitted by applicable law, in no event shall the Company, its directors, employees or affiliates be liable for any indirect, incidental, special, consequential or punitive damages, including without limitation loss of profits, trading losses, data, goodwill, or other intangible losses, arising out of or in connection with your use of, or inability to use, the Service.
Our aggregate liability for any claim arising out of or relating to these Terms or the Service is limited to the amount you paid us in the twelve (12) months preceding the event giving rise to the claim.
Nothing in these Terms excludes or limits liability that cannot be excluded under mandatory law, including liability for gross negligence, wilful misconduct, or personal injury caused by our negligence.
Our processing of personal data is described in our Privacy Policy, which forms an integral part of these Terms.
We may update these Terms from time to time. When we make material changes, we will notify registered users by email and post the updated version on this page at least 30 days before the changes take effect. Your continued use of the Service after the effective date constitutes acceptance of the updated Terms; if you do not agree, you may cancel your Subscription before the changes take effect.
These Terms are governed by the laws of Portugal, excluding its conflict-of-laws rules and the United Nations Convention on Contracts for the International Sale of Goods.
The courts of Lisbon, Portugal, have exclusive jurisdiction over any dispute arising out of or relating to these Terms or the Service, except that, if you are a consumer resident in the European Union, you may also bring proceedings in the courts of your country of residence, and the mandatory consumer-protection law of that country continues to apply (Art. 6(2) Rome I Regulation).
If you are a consumer and we cannot resolve a dispute amicably, you may use the European Commission's Online Dispute Resolution platform at ec.europa.eu/consumers/odr. In Portugal, you may also refer disputes to the Centro de Arbitragem de Conflitos de Consumo de Lisboa (centroarbitragemlisboa.pt), among other authorised entities listed at consumidor.gov.pt. We are not obliged to participate in alternative dispute resolution unless required by law, but we will consider any reasonable request to do so.
For any question about these Terms, please contact us at support@gammaflip.io or by post at the registered office address in Section 1.
