Paid Services

Last Updated: 23 September, 2024 | Date effective: 23 September, 2024

Services provided by Linus may be free or we may charge a fee for using the Services. If you are using a free version of the Services, we will notify you before any Services you are then using begin carrying a fee, and if you wish to continue using such Services, you must pay all applicable fees for such Services. Note that if you elect to receive text messages through the Services, data and message rates may apply. Any and all such charges, fees or costs are your sole responsibility. You should consult with your wireless carrier to determine what rates, charges, fees or costs may apply to your use of the Services.


  1. Paid Services. Certain of our Services may be subject to payments now or in the future (the “Paid Services”). Current paid services include "TurboLinus", our premium offering, which is available for purchase under both an annual subscription ($149.99 per year) as well as a monthly subscription ($24.99 per month). Please note that any payment terms presented to you in the process of using or signing up for a Paid Service are deemed part of these Terms. For example, some Paid Services will charge a fee for downloading or installing the Services through the App Store (as defined below) linked to your specific device. You agree to comply with, and your license to use our mobile application is conditioned upon your compliance with, such App Store terms and conditions. Any refunds relating to the applications or inquiries regarding refunds relating to the applications shall be handled solely by the applicable App Store in accordance with such App Store's terms and conditions.

  2. Billing. We use a third-party payment processor (the “Payment Processor”) to bill you through a payment account linked to your account on the Services (your “Billing Account”) for use of the Paid Services. The processing of payments will be subject to the terms, conditions and privacy policies of the Payment Processor in addition to these Terms. Currently, we use Stripe, Inc. as our Payment Processor. You can access Stripe's Terms of Service at https://stripe.com/us/checkout/legal and their Privacy Policy at https://stripe.com/us/privacy. We are not responsible for any error by, or other acts or omissions of, the Payment Processor. By choosing to use Paid Services, you agree to pay us, through the Payment Processor, all charges at the prices then in effect for any use of such Paid Services in accordance with the applicable payment terms, and you authorize us, through the Payment Processor, to charge your chosen payment provider (your “Payment Method”). You agree to make payment using that selected Payment Method. We reserve the right to correct any errors or mistakes that the Payment Processor makes even if it has already requested or received payment.


  3. Payment Method. The terms of your payment will be based on your Payment Method and may be determined by agreements between you and the financial institution, credit card issuer or other provider of your chosen Payment Method. If we, through the Payment Processor, do not receive payment from you, you agree to pay all amounts due on your Billing Account upon demand.


  4. Recurring Billing. Some of the Paid Services may consist of an initial period, for which there is a one-time charge, followed by recurring period charges as agreed to by you. By choosing a recurring payment plan, you acknowledge that such Services have an initial and recurring payment feature and you accept responsibility for all recurring charges prior to cancellation. WE MAY SUBMIT PERIODIC CHARGES (E.G., MONTHLY) WITHOUT FURTHER AUTHORIZATION FROM YOU, UNTIL YOU PROVIDE PRIOR NOTICE (RECEIPT OF WHICH IS CONFIRMED BY US) THAT YOU HAVE TERMINATED THIS AUTHORIZATION OR WISH TO CHANGE YOUR PAYMENT METHOD. SUCH NOTICE WILL NOT AFFECT CHARGES SUBMITTED BEFORE WE REASONABLY COULD ACT. TO TERMINATE YOUR AUTHORIZATION OR CHANGE YOUR PAYMENT METHOD, GO TO YOUR ACCOUNT SETTINGS.


  5. Current Information Required. YOU MUST PROVIDE CURRENT, COMPLETE AND ACCURATE INFORMATION FOR YOUR BILLING ACCOUNT. YOU MUST PROMPTLY UPDATE ALL INFORMATION TO KEEP YOUR BILLING ACCOUNT CURRENT, COMPLETE AND ACCURATE (SUCH AS A CHANGE IN BILLING ADDRESS, CREDIT CARD NUMBER, OR CREDIT CARD EXPIRATION DATE), AND YOU MUST PROMPTLY NOTIFY US OR OUR PAYMENT PROCESSOR IF YOUR PAYMENT METHOD IS CANCELED (E.G., FOR LOSS OR THEFT) OR IF YOU BECOME AWARE OF A POTENTIAL BREACH OF SECURITY, SUCH AS THE UNAUTHORIZED DISCLOSURE OR USE OF YOUR USER NAME OR PASSWORD. CHANGES TO SUCH INFORMATION CAN BE MADE IN YOUR ACCOUNT SETTINGS. IF YOU FAIL TO PROVIDE ANY OF THE FOREGOING INFORMATION, YOU AGREE THAT WE MAY CONTINUE CHARGING YOU FOR ANY USE OF PAID SERVICES UNDER YOUR BILLING ACCOUNT UNLESS YOU HAVE TERMINATED YOUR PAID SERVICES AS SET FORTH ABOVE.


  6. Change in Amount Authorized. If the amount to be charged to your Billing Account varies from the amount you preauthorized (other than due to the imposition or change in the amount of state sales taxes), you have the right to receive, and we shall provide, notice of the amount to be charged and the date of the charge before the scheduled date of the transaction. Any agreement you have with your payment provider will govern your use of your Payment Method. You agree that we may accumulate charges incurred and submit them as one or more aggregate charges during or at the end of each billing cycle.


  7. Auto-Renewal for Paid Services. Unless you opt out of auto-renewal, which can be done through your account settings, any Paid Services you have signed up for will be automatically extended for successive renewal periods of the same duration as the subscription term originally selected, at the then-current non-promotional rate. To change or resign your Paid Services at any time, go to account settings or, for mobile applications, cancel your subscription in the subscription management section of the applicable App Store. If you terminate a Paid Service, you may use your subscription until the end of your then-current term, and your subscription will not be renewed after your then-current term expires. However, you will not be eligible for a prorated refund of any portion of the subscription fee paid for the then-current subscription period. IF YOU DO NOT WANT TO CONTINUE TO BE CHARGED ON A RECURRING MONTHLY BASIS, YOU MUST CANCEL THE APPLICABLE PAID SERVICE THROUGH YOUR ACCOUNT SETTINGS OR TERMINATE YOUR LINUS ACCOUNT BEFORE THE END OF THE RECURRING TERM. PAID SERVICES CANNOT BE TERMINATED BEFORE THE END OF THE PERIOD FOR WHICH YOU HAVE ALREADY PAID, AND EXCEPT AS EXPRESSLY PROVIDED IN THESE TERMS, LINUS WILL NOT REFUND ANY FEES THAT YOU HAVE ALREADY PAID.


  8. Reaffirmation of Authorization. Your non-termination or continued use of a Paid Service reaffirms that we are authorized to charge your Payment Method for that Paid Service. We may submit those charges for payment and you will be responsible for such charges. This does not waive our right to seek payment directly from you. Your charges may be payable in advance, in arrears, per usage, or as otherwise described when you initially selected to use the Paid Service.


  9. Free Trials and Other Promotions. Any free trial or other promotion that provides access to a Paid Service must be used within the specified time of the trial. You must stop using a Paid Service before the end of the trial period in order to avoid being charged for that Paid Service. If you cancel prior to the end of the trial period and are inadvertently charged for a Paid Service, please contact us at [email protected].
