    You may be required to register for the Chess Cloud Analysis Service. To create an account, you must complete the registration process by providing Chessify with the information prompted by the registration form, including e-mail address (username) and password. You agree to provide us with complete and accurate information when you register for the Cloud Analysis Service, and to keep such information up to date.

You agree to notify Chessify immediately of any unauthorized use of your account or any other breach of security relating to your account or your use of the Service.

    Chessify may access your account, or information associated with your account, to provide support or maintenance, for security-related reasons, or any other business purpose. You acknowledge and consent to such access.

  • 2. Free Trial Period

    Chessify may offer a one-time free trial period during which you can try the Cloud Analysis Service for 2 hours from the time you register on Chessify without pre-paying ("Free Trial Period"). To receive a Free Trial, go to https://chessify.me/analysis , create an account, and then verify it via the link we send to your email address. The Free Trial does not require any information about your credit card or other payment methods.

    During the Free Trial Period, you receive 200 coins which you can use to rent any of Chessify's cloud servers and chess engines. After your Free Trial Period expires, you lose all your unused coins and become a free subscriber, which means that you’ll be able to analyze with 1 MN/s speed Stockfish only. In order to get access to higher-speed servers, you should subscribe to one of the paid plans available at chessify.me/pricing .

    Chessify reserves the right to modify, cancel and/or limit the Free Trial Period offer at any time.

  • 3. Fees

    Chessify offers different payment models for its cloud analysis service, including, but without limitation to, subscription plans (“Plan(s)”), One-time payment for coins (“Coin(s)”), special packages (“Special Package(s)”) payable via an invoice.

    As an express condition of your use of and access to the Chessify Cloud Analysis Service, you agree to pay all fees applicable to your Plan, any other fees for additional services you may purchase, and any applicable taxes in connection with your use of the Analysis Service.

    To view the available Plans, go to https://chessify.me/pricing . The special packages are usually discussed via email. You can contact Us at info@chessify.me for such a package.

    • 3.1. Coins

      You may buy coins without paying for a subscription first, in which case you will be able to rent all of Chessify’s coin-based servers and engines but you will not have access to the free up to 100 MN/s servers for unlimited analysis. You can find the option for buying Coins at https://chessify.me/pricing below the subscription plans. The options start from 5 USD and go up to 10,000 USD. Each price range offers certain bonus coins; by purchasing more Coins you qualify for higher bonuses.

      All payments for Coins are non-recurring and do not auto-renew after the specified expiry date. Your Coins are valid for 6 months since the date you last purchased Coins. After one year, you irreversibly lose all your unused coins. To avoid losing your remaining Coins, you can simply make a new purchase or subscribe to one of the subscription plans.

    • 3.2. Special Packages

      The Special Packages are created based on the training needs of the user. To create a Special Package, you should contact Chessify at info@chessify.me and either state the number of coins you want to receive or request a consultation. The validity date, payment method, as well as the number of coins of the Special Package, are all agreed with the user through email.

      When the Special Package expires, you lose all unused coins as well the access to the free up to 100 MN/s speed server unless agreed otherwise before the start of your package. To avoid losing your remaining coins and access to the free server, you should buy a new package or subscribe to any of the Plans before the expiry date of your current package.

      Chessify may, but is not obliged to, do exceptions for the users who buy a new package after the expiry date. You should contact us at info@chessify.me if you want to recover your lost coins by buying a new package.

    • 3.3. Subscription Plans

      The subscription plans of Chessify Cloud Analysis Service include, but may not be limited to, "Free Plan," "Amateur Plan, "Master Plan," and "GM Plan." When you register on Chessify, you automatically become a free subscriber, which allows you to analyze with Stockfish at 1 MN/s speed. For faster analysis, you should subscribe to one of Our paid plans. The Amateur plan offers 10 MN/s speed for unlimited analysis with Stockfish, asmFish, SugaR, Koivisto, and Berserk, while the Master and GM plans give access to 100 MN/s speed for the same engines. The GM plan also provides 10,000 Coins for higher-speed servers and other engines.

      Your Plan will renew automatically and continue month-to-month or year-to-year (depending on your Plan) unless and until you cancel your Plan or we terminate it, in each case pursuant to these Terms of Use (see Section 3.6 (Account Cancellation) and Section 12 (Term and Termination)). You must cancel your Plan before it renews in order to avoid fees due under the next billing cycle. To view the specific details of your Plan, including the commencement date of your next renewal period, log in at https://chessify.me/analysis , click on your profile icon from the top right corner, and check the right side for details.

      We will bill the fees due under your Plan to the credit card you provide to us during checkout (or to a different credit card if you change your payment information). You acknowledge that the amount billed for each renewal period may vary due to promotional offers, changes in your Plan, and changes in applicable taxes, and you authorize us to bill you the corresponding amounts.

      In case your payment for the next billing period fails for any reason, Stripe will attempt to bill your card up to four times and then cancel your subscription automatically if the attempts are not successful. Once your subscription is canceled, you will lose access to the features offered by the subscription plan. Your coins, however, will continue to be valid for 6 months from the day they were purchased.

      We reserve the right to deactivate your access to the Analysis Service for failure to pay applicable fees as described in these Terms.

    • 3.4. DecodeChess Add-On

      The DecodeChess add-on provides textual explanations for the Stockfish engine analysis of a given chess position. It helps users understand the reasoning behind the engine's analysis, and improve their chess skills.

      All registered Chessify users have access to one free Decode per day until June 30, 2023. Additional Decodes can be purchased using Chessify Coins at the rate of 20 coins per Decode. We also offer a yearly plan for DecodeChess that provides unlimited Decodes. This plan is discounted by 50% until June 30, 2023, and costs $42. This is a non-recurring payment and will automatically expire after a year.

      Please note that the DecodeChess add-on is a separate service from Chessify and is provided by DecodeChess.

      To see what kind of user data we share with DecodeChess, please read our Privacy Policy .

    • 3.5. Changes in Fees

      We may, upon any notice required by applicable law, change the fees for the Service at any time or require new fees or charges. Such changes will be effective immediately upon posting on Our Website; provided, however, that such fee changes will be effective only as to prospective Service orders (including renewals) accepted by Chessify after the effective date of such change. Please be aware that any discounts applicable to previous subscriptions may not apply to renewed subscriptions.

    • 3.6. Payment Terms and Refunds

      The Website uses Stripe for all its online transactions. You can learn more information about Stripe at https://stripe.com .

      All fees for your Plan will be billed to your credit card or alternative payment method offered by Chessify. You authorize the card issuer to pay any amounts described herein and in your Plan and authorize Us (or a billing agent acting on Our behalf) to continue charging all such amounts to your credit card account until you or we cancel or terminate your Plan as provided herein or these amounts are paid in full, whichever is later. You must provide current, complete, and accurate billing and credit card information.

      The fees for your Plan are billed in advance and are non-refundable. No refunds or credits will be provided for partial months of the Service, upgrades/ downgrades, or for months unused with an open account. We reserve the right to deactivate your access to the Service for failure to pay applicable fees as described in these Terms. Unless otherwise stated, all fees are stated in U.S. Dollars.

    • 3.7. Upgrade and Downgrade Terms

      If you downgrade your Plan level, your credit card will automatically be charged the new rate beginning with your next billing cycle. Downgrading your Plan may cause the loss of account features or capacity starting from the next cycle.

      During plan upgrades, Chessify uses a prorated (i.e., proportionate) billing model. Our system calculates the amounts you should pay for the time spent on each subscription plan. For example, if you want to upgrade from the $8 Amateur plan to the $35 Master plan halfway through the monthly billing period, you will be charged an additional $13.50: +17.50 USD for the remaining time on the new Master plan and -4 USD for unused time on your Amateur plan.

      If you upgrade, your next-month payment will occur on the date of your initial subscription creation, and you will continue to be charged the new amount beginning with your next billing cycle.

    • 3.8. Subscription Cancellation

      The only valid method for canceling your Plan is via the cancellation button provided on your account page, accessible after logging in to the Chessify Website at https://chessify.me/analysis . Requests to cancel by e-mail or phone are not considered and do not accomplish cancellation.

      If you cancel your Plan before the end of your current pre-paid period, you will not be charged again for your Plan beginning with the next billing cycle. If you cancel your Plan, you will lose all access, upon the expiration of your current pre-paid period, to the Service (see Section 12 (Term and Termination) for additional details).

  • 11. Dispute Resolution

    To expedite resolution and control the cost of any dispute, controversy, or claim related to these Terms and Conditions (each a "Dispute" and collectively, the “Disputes”) brought by either you or us (individually, a “Party” and collectively, the “Parties”), the Parties agree to first attempt to negotiate any Dispute (except those Disputes expressly provided below) informally for at least 60 days before initiating arbitration. Such informal negotiations commence upon written notice from one Party to the other Party.

    • 11.1. Binding Arbitration

      If the Parties are unable to resolve a Dispute through informal negotiations, the Dispute (except those Disputes expressly excluded below) will be finally and exclusively resolved by binding arbitration. YOU UNDERSTAND THAT WITHOUT THIS PROVISION, YOU WOULD HAVE THE RIGHT TO SUE IN COURT AND HAVE A JURY TRIAL.

      The arbitration shall be commenced and conducted under the Commercial Arbitration Rules of the American Arbitration Association ("AAA") and, where appropriate, the AAA’s Supplementary Procedures for Consumer-Related Disputes ("AAA Consumer Rules"), both of which are available at the AAA website https://www.adr.org .

      Your arbitration fees and your share of arbitrator compensation shall be governed by the AAA Consumer Rules and, where appropriate, limited by the AAA Consumer Rules. [If such costs are determined by the arbitrator to be excessive, we will pay all arbitration fees and expenses.]

      The arbitration may be conducted in person, through the submission of documents, by phone, or online. The arbitrator will make a decision in writing, but need not provide a statement of reasons unless requested by either Party.

      The arbitrator must follow applicable law, and any award may be challenged if the arbitrator fails to do so. Except where otherwise required by the applicable AAA rules or applicable law, the arbitration will take place in the USA, Delaware.

      Except as otherwise provided herein, the Parties may litigate in court to compel arbitration, stay proceedings pending arbitration, or confirm, modify, vacate, or enter judgment on the award entered by the arbitrator.

      If for any reason, a Dispute proceeds in court rather than arbitration, the Dispute shall be commenced or prosecuted in the state and federal courts located in [name of county] County, [name of state], and the Parties hereby consent to and waive all defenses of lack of personal jurisdiction, and forum non-conveniens with respect to venue and jurisdiction in such state and federal courts.

      Application of the United Nations Convention on Contracts for the International Sale of Goods and the Uniform Computer Information Transaction Act (UCITA) are excluded from these Terms and Conditions.

      In no event shall any Dispute brought by either Party related in any way to the Site be commenced more than 1 year after the cause of action arose. If this provision is found to be illegal or unenforceable, then neither Party will elect to arbitrate any Dispute falling within that portion of this provision found to be illegal or unenforceable, and such Dispute shall be decided by a court of competent jurisdiction within the courts listed for jurisdiction above, and the Parties agree to submit to the personal jurisdiction of that court.

    • 11.2. Restrictions

      The Parties agree that any arbitration shall be limited to the Dispute between the Parties individually. To the full extent permitted by law, (a) no arbitration shall be joined with any other proceeding; (b) there is no right or authority for any Dispute to be arbitrated on a class-action basis or to utilize class action procedures; (c) there is no right or authority for any Dispute to be brought in a purported representative capacity on behalf of the general public or any other persons.

    • 11.3. Exceptions to Informal Negotiations

      The Parties agree that the following Disputes are not subject to the above provisions concerning [informal negotiations and] binding arbitration: (a) any Disputes seeking to enforce or protect, or concerning the validity of, any of the intellectual property rights of a Party; (b) any Dispute related to or arising from, allegations of theft, piracy, invasion of privacy, or unauthorized use; and (c) any claim for injunctive relief.

      If this provision is found to be illegal or unenforceable, then neither Party will elect to arbitrate any Dispute falling within that portion of this provision found to be illegal or unenforceable, and such Dispute shall be decided by a court of competent jurisdiction within the courts listed for jurisdiction above, and the Parties agree to submit to the personal jurisdiction of that court.
