Terms and conditions

General Terms and Conditions of VivoSensMedical GmbH for sales contracts concluded with consumers (private customers).

The following general terms and conditions (GT&C) apply for all sales contracts concluded via the online shop www.ovularing.com between VivoSensMedical GmbH, Limburgerstr. 74 C, 04229 Leipzig, Germany, telephone +49 341 355 820 99 (VivoSensMedical) and the buyer (hereinafter referred to as “you”).



1.1 The business relationship between VivoSensMedical ("us") and the customer ("you") is exclusively subject to the following GT&C in their version valid at the time of the online order. Deviating individual agreements shall only apply where these are agreed in writing.

1.2 Our offer is aimed at consumers as defined by § 13 BGB - German Civil Code. You are a consumer, to the extent that the purpose of the ordered goods and services cannot be primarily attributed to your commercial or independent professional activity. In contrast, you are a businessperson as per § 14 BGB if you are acting in your commercial or professional capacity at the time of concluding the contract.



2.1 OvulaRing comprises a plastic ring, a biosensor, a reading device and the possibility to evaluate data via a web-based software. This evaluation software is made available to you on a virtual server at www.myovularing.com. The www.myovularing.com site is made available by us. Please note our data protection notice (figure 12) for use of the evaluation software.

We offer you starter or application extension packages for 3, 6 or 12 months at www.ovularing.com. With the monthly package you acquire the option of using OvulaRing including the evaluation software for 3, 6 or 12 months.

2.2 VivoSensMedical GmbH is the manufacturer of the OvulaRing. The company is registered in the commercial register of Leipzig District Court under HRB 27028.

2.3 In addition, we also market OvulaRing. Sales contracts in these countries that are concluded via the online shop www.ovularing.com come into effect between you and us.

2.4 With the delivery of the product package that you have selected, including instructions for use, you receive your access details for the personal account set up for you at “myovularing.com”.

(a) During your selected period of application you can upload your temperature data from your biosensor with the aid of the reading device and, should you choose so, add information to the evaluation software in order to include this in the evaluation of the temperature data. Following the completion of your selected period of application (3, 6or 12 months) the uploading or addition of information is no longer possible.

(b)The selected period of application (3, 6 or 12 months) begins on the day on which the first temperature data are recorded with the biosensor, at the latest one month after the date of shipping your OvulaRing package. If we ship the 3-month starter package that you have ordered on 15 June, the period of application (irrespective of when you utilise the biosensor for the first time and record temperature data) will consequently end on 15 October at the latest. If you begin utilising the biosensor directly after receiving the package, e.g. on 20 June, the period of application will end on 20 September.

(c) In the event of pregnancy or illness that renders your use of the OvulaRing impossible, you may suspend use in the scope of a 6  or 12-month package. This also applies to the purchase of a 3 month starter package and the subsequent purchase of a 3 month application extension. Suspension in the scope of a 3-month package is not possible. Pauses in application are only possible for full application months. For example, if you have ordered a 12-month package and your application commences on 15 July and you inform us on 25 September that you wish to suspend use, we will record suspended use from 15 October and credit you with a 9-month application period. If you inform us of the suspension of use by 15 September, we will credit you with a 10-month application period. Depending on the length of the pause, you may require a replacement sensor for a service fee of € 45.00 each. To suspend application please contact our customer service on the service telephone number +49 341 355 820 99 (Mon-Fri 9 am-4 pm) or via e-mail (info@ovularing.com).

2.5 Following the ending of the period of application (see figure 2.4(b)) the temperature data shall be stored for a further 24 months and made available to you by the manufacturer via the evaluation software myovularing. You have the opportunity to store this data locally on your PC or a data carrier. On request we will be happy to make your temperature data available in a generally legible .csv format for your own use.

Following on from the aforementioned 24 months the cycle data collected shall be stored by VivoSensMedical GmbH for further research, without any personal reference. The reference to personal details of the user shall be deleted. The temperature data is subsequently only available in anonymised form, i.e. the attribution of the temperature data to a user is not possible from this time on

You must grant us a reasonable time period for supplementary performance. During this time you shall not be entitled to reduce the purchase price or withdraw from the contract.

8.4 If, despite two improvements, the defect has not been rectified, we do not intend to provide supplementary performance or are not able to do so, if this fails to occur within a reasonable period of time or if the supplementary performance fails for whatever reason, you may choose - where the defect is not merely insignificant – to withdraw from the contract or demand a corresponding reduction in the purchase price (reduction).
