Subscription fee and subscription period

Subscription payments for our app are made periodically, accordingly to the package you selected when you signed up: every one month, every three months or once a year. At the end of your subscription period, your subscription will be automatically renewed. If you do not wish to continue your subscription, you may terminate your User Account before your current subscription period ends. Subscription prices may change from time to time and by continuing to use Natural Cycles you agree to the price change.

Payments for the use of the Services (“Subscription Fees”) are made periodically in advance. Each payment covers a subscription period (“Subscription Period”) during which the User may access the Services. A Subscription Period can be one month, three months or one year as offered by the Services.


Subscription Fees must be paid using a lawfully issued credit or debit card for which you have authorization to make a charge. Natural Cycles reserves the right to block access to your User Account until a valid credit or debit card has been provided to cover all charges incurred by you. You are solely responsible for any late payment charges or other charges incurred by you as a result of your use of a credit or debit card to pay a subscription fee.


At the end of each Subscription Period, your subscription will be automatically renewed for one month, three months or one year subscription each time (depending on whether your current Subscription Period is one month, three months or one year respectively). To avoid your subscription period being automatically renewed you may terminate your subscription at your User Account before the last day of your current Subscription Period. The termination will take effect from the last day of your current Subscription Period.


In certain cases, such as discounts or promotions, the Subscription fee may include a basal thermometer or other relevant physical goods. The goods are considered marketing gifts and do not contribute to the purchase price. Natural Cycles has no obligation to replace, or in any other way compensate you for, faulty marketing gifts or marketing gifts that have not arrived. Natural Cycles offers no right to return such marketing gifts, as you have paid for the subscription and not the marketing gifts.


Natural Cycles reserves the right to change the price for a Subscription Period at any time. Price changes for a Subscription Period will take effect at the start of the next Subscription Period following the date of the price change and will be communicated to Users affected by the change before such date. By continuing to use the Services after the price change takes effect, you agree to accept the new price. The prices for the Products in the Webshop are subject to change without notice.


You may cancel your subscription of the Services at any time, and you will continue to have access to the Services throughout your pre-paid Subscription Period. We do not provide refunds, right to return for a purchased subscription, credits for any partially used subscription or unused User Account, or by reason of your dissatisfaction with the Services. As the subscription gives you access to the Services (which are digital and not provided via a physical medium) instantaneously after the purchase, Natural Cycles does not offer a right of return (such as refunding the subscription fee). To cancel your Subscription, go to the profile settings when logged in on your User Account and follow the instructions for cancellation.

Return of physical products

Our return policy for items purchased through the Webshop lasts for fourteen (14) days. Please read below to understand more about our Terms for returns and refunds.

Our return policy for non-digital Products that are purchased through the Webshop lasts for fourteen (14) days. If more than 14 days have gone by since you have received your purchased product, we cannot offer you a refund or an exchange.


To be eligible for a return, the “Item” (a non-digital Product purchased from our Webshop that you wish to return for a refund) must be shipped to us in the unused condition in which you received it in with the original intact packaging. Several types of goods cannot be returned for a refund. This includes perishable goods (such as ovulation and pregnancy tests), intimate and sanitary goods, as well as downloadable software products.


For Items that are defective and for which you complete a formal customer complaint (“Defect Items”), the complaint is eligible for a refund even if it does not fulfill the requirements of paragraph 10.2 above.


To return an Item or a Defect Item, ship the Item including the receipt or proof of purchase to the following address: Natural Cycles Nordic AB, Luntmakargatan 26, 111 37 Stockholm, Sweden.


Shipping costs for returning an Item is non-refundable, unless you are returning Defect Items which are refundable to a reasonable amount. You may request Defect Items to be replaced by a comparable Product. Depending on where you live, the time it may take for your exchanged product to reach you may vary. Some Products are limited in quantity and might be impossible to replace.


In the case of a refund, you are responsible for the product until it has been returned and we do not guarantee that your returned Item will be refunded until it is successfully returned to us. Do not send the Items back to the manufacturer.


We reserve the right to refuse to issue a refund or only issue a partial refund on returned Items (e.g. when a returned Item does not fulfill the return terms as set out above or when we are not able to review an Item because it has not been returned to us successfully or in an acceptable state).


Once your return is received and inspected, we will (if applicable) send you an email to notify you that we have received your returned Item and notify you of the status of your refund (approval or rejection). If approved, then your refund will be processed, and a credit will automatically be applied to your credit card or original method of payment within a certain amount of days. If rejected, we will provide information on why that is the case.


If the Item when purchased and shipped directly to you was marked as a gift, you can (when returning the Item) request to receive a gift credit for the value of your return. Once the returned Item is received by us, a gift certificate will be mailed to you. If the Item wasn’t marked as a gift when purchased, or the gift giver had the Products shipped to themselves to give to you later, we will send a refund only to the original purchaser.
