Terms & Conditions

1 Scope

These Terms & Conditions (hereinafter "Terms") apply to all contracts concluded between Lifestyle Monitors (hereinafter "the Provider") and the customer (hereinafter "the Customer" or "the Consumer") via the website lifestylemonitors.com and the associated web application app.stresschecker.com. They also apply to contracts concluded through third-party intermediary platforms (e.g. the machtfit platform), provided the Provider acts as the seller.

For the purposes of these Terms:

• A Consumer is any natural person who enters into a legal transaction for purposes that are predominantly outside their trade, business or profession.
• A Business customer is any natural or legal person, or partnership with legal capacity, acting in the exercise of their trade, business or profession when entering into a legal transaction.

The version of these Terms in force at the time the contract is concluded shall apply. Deviating terms proposed by the Customer are not accepted unless the Provider expressly agrees to them in writing.

2 Contracting party & contact

Further information about the Provider can be found in the Imprint.

3 Formation of the contract

The presentation of products and subscriptions in the online shop does not constitute a legally binding offer, but an invitation to place an order (invitatio ad offerendum).

A contract concluded via our own website comes about in the following steps:

1. The Customer selects the desired product or subscription.
2. The Customer enters their details and selects a payment method.
3. Before submitting the order, the Customer can review and correct all details.
4. By clicking the button "Order with obligation to pay", "Subscribe" or an equivalent button, the Customer submits a binding offer.
5. The Provider confirms receipt of the order without delay by email (order confirmation).
6. The contract comes into effect when the Provider accepts the offer by means of a separate order acceptance, by supplying the activation details, or by delivering the goods.

Contracts concluded through intermediary platforms: Where the Provider offers products through third-party intermediary platforms (e.g. machtfit), the contract between the Customer and the Provider is concluded in accordance with the booking process of the platform concerned — as a rule upon receipt of the booking confirmation which the platform sends to the Customer on the Provider's behalf. These Terms also apply to such contracts; the platform operator's own terms of use apply additionally to the use of the platform itself.

The text of the contract is stored by the Provider and sent to the Customer by email after the contract is concluded. The version of these Terms currently in force is available on the website.

4 Products & services

The Provider offers the following products and services via the website:

StressChecker Complete – subsequent years: After the first year has elapsed, the Customer receives a renewal offer in good time before expiry, at a price of € 69.00 per further year (StressChecker Annual Subscription, without additional hardware). There is no automatic renewal; the Customer actively decides whether to renew.

5 Prices and payment terms

All prices stated are final prices and include statutory VAT. VAT is charged at the rate applicable in the Customer's country of residence and is remitted in the Netherlands under the One-Stop Shop (OSS) scheme.

Additional shipping costs apply only to products containing physical components (StressChecker Complete) and are clearly displayed before the order is completed.

Accepted payment methods:

• Stripe (Visa/Mastercard credit card, SEPA direct debit) – for recurring subscriptions (StressChecker Pro S)
• PayPal – for one-off purchases and annual subscriptions
• Intermediary platforms – for bookings made through platform partners (e.g. machtfit), payment is made via the payment method provided by that platform

Due date:

• For one-off purchases, the purchase price is due when the contract is concluded.
• For recurring subscriptions, the relevant amount is collected or debited automatically at the start of each billing period (month or year).
• The Customer is informed before each payment in accordance with statutory requirements and the terms of the payment service providers.

Late payment: In the event of late payment, the Provider is entitled to charge statutory default interest and to suspend access to the digital services until payment has been made in full.

6 Supply of digital content

The digital content (StressChecker, StressChecker Pro) is supplied in accordance with the applicable statutory provisions on digital content and digital services.

Supply takes place through:

• Sending an activation code by email once payment has been received or — in particular with StressChecker Complete — enclosing the activation code in the product packaging
• Supply of the digital service begins when the Customer activates the code on app.stresschecker.com (see Section 12); the customer account is unlocked upon activation
• For StressChecker Complete, dispatch of the Bluetooth heart rate monitor by post in addition

System requirements:

• A current web browser (Chrome, Edge, Firefox or Safari, each in its current version)
• A stable internet connection
• A compatible heart rate monitor (USB or Bluetooth Low Energy)
• A webcam or microphone is not required; measurement takes place exclusively via the heart rate monitor

Updates and conformity: Throughout the entire term of the contract, the Provider supplies the updates necessary to maintain the conformity of the digital content, including security updates.

Defects: Statutory warranty rights apply to defects in digital content.

7 Delivery of physical components

This section applies exclusively to orders containing physical components (in particular StressChecker Complete with Bluetooth heart rate monitor).

Delivery is made to the delivery address specified by the Customer within the European Union. For bookings made through intermediary platforms, delivery is made to the delivery address specified or transmitted during that platform's booking process.

Delivery times (working days after receipt of payment):

• Germany: 2–4 working days
• Austria/Switzerland: 3–5 working days
• Other EU countries: 5–7 working days

If a product is unavailable, the Customer will be informed without delay. Any payments already made will be refunded promptly in that case.

For consumers, the risk of accidental loss and accidental deterioration of the goods passes to the Customer only upon handover of the goods. For business customers, the statutory provisions on the passing of risk on dispatch apply.

Retention of title: The goods delivered remain the property of the Provider until payment has been made in full.

9 Cancellation & cancellation button

In addition to the cancellation button, the following alternative cancellation routes are available:

• Via the web application: After signing in at app.stresschecker.com, you will find the "Manage subscription" button in the "Licence" area. This opens the customer portal of our payment service provider Stripe, where you can carry out the cancellation yourself, update your payment method or download invoices.
• Direct link to the customer portal: Every invoice email from Stripe contains a personalised link to the customer portal, which lets you manage your subscription without signing in again.
• By email to info@lifestylemonitors.com with the subject "Contract cancellation", stating the order number or the email address used to take out the subscription.

Effect of cancellation:

• Cancellation takes effect at the end of the current billing period (month or year).
• The Customer retains full access to the digital services until the end of the period paid for.
• No pro-rata refund is given where cancellation takes place within a billing period that has already begun.
• The Customer receives confirmation of the cancellation by email, stating the effective date.
• Where cancellation is made via the Stripe customer portal or the web application, confirmation is generally sent within a few minutes; where cancellation is made by email, confirmation follows within two working days at the latest.

Extraordinary termination: The right to terminate for good cause (e.g. material defects, price increase) remains unaffected.

10 Right of withdrawal

Consumers have a statutory right of withdrawal. This applies regardless of whether the contract was concluded via the Provider's own website or through an intermediary platform.

Overview of withdrawal periods:

To exercise the right of withdrawal, the Consumer must inform the Provider of their decision to withdraw from the contract by means of a clear statement (by letter or email). The detailed withdrawal instructions and the model withdrawal form can be found in Section 11.

11 Withdrawal instructions

Right of withdrawal:

You have the right to withdraw from this contract within 14 days without giving any reason.

The withdrawal period is 14 days:

• for digital subscriptions: from the day the contract is concluded;
• for StressChecker Complete: from the day on which you, or a third party named by you who is not the carrier, take possession of the Bluetooth monitor.

To exercise your right of withdrawal, you must inform us:

of your decision to withdraw from this contract by means of a clear statement (e.g. a letter sent by post or an email). You may use the attached model withdrawal form for this purpose, although it is not obligatory.

Consequences of withdrawal:

If you withdraw from this contract, we shall reimburse to you all payments received from you, including the costs of delivery (with the exception of the supplementary costs resulting from your choice of a type of delivery other than the least expensive type of standard delivery offered by us), without undue delay and in any event not later than fourteen days from the day on which we are informed about your decision to withdraw from this contract.

We will carry out such reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.

For goods: We may withhold reimbursement until we have received the goods back or you have supplied evidence of having sent back the goods, whichever is the earliest. You shall send back the goods without undue delay and in any event not later than fourteen days from the day on which you communicate your withdrawal from this contract to us. The Customer bears the direct cost of returning the goods.

Diminished value: You are only liable for any diminished value of the goods resulting from handling other than what is necessary to establish the nature, characteristics and functioning of the goods.

12 Exclusion of the right of withdrawal

The right of withdrawal lapses early in the following cases:

For digital content (StressChecker, StressChecker Pro):

The right of withdrawal for digital content not supplied on a tangible medium lapses where:

• the Provider has begun performance of the contract after the Consumer has expressly consented to the Provider beginning performance before the withdrawal period has expired, and
• the Consumer has at the same time acknowledged that, by giving consent, they lose their right of withdrawal once performance of the contract begins.

For StressChecker Complete, the lapse of the right of withdrawal through activation relates exclusively to the digital service (software licence). The right of withdrawal for the Bluetooth heart rate monitor (goods) is unaffected by activation and continues for the statutory period.

For goods (StressChecker Complete):

The right of withdrawal is excluded for:

• sealed goods which are not suitable for return for reasons of health protection or hygiene, where the seal has been removed after delivery;
• goods made to the Customer's specifications or clearly tailored to personal requirements.

13 Software and usage licence

On taking out a subscription, the Customer receives a limited, non-exclusive, non-transferable licence to use the web application app.stresschecker.com and the functions it contains.

Permitted use:

• Personal, non-commercial use of the StressChecker application (consumer subscription)
• Professional use within your own practice or professional activity (StressChecker Pro)
• Use via compatible devices with a web browser
• Analysis of your own measurement data

Not permitted:

• Passing on access details or activation codes to third parties
• Reverse engineering, decompiling or modifying the software
• Use for unlawful purposes
• Circumventing technical protection measures
• Use of a single consumer subscription by several different people

Breaches of these usage provisions entitle the Provider to terminate the contract with extraordinary effect and to assert further claims.

14 Liability for defects (warranty)

The statutory rights in respect of defects apply, both for goods and for digital content.

Warranty period:

• For new goods (Bluetooth heart rate monitor): 2 years from delivery
• For digital content and subscriptions: for the entire term of the contract

In the event of a defect, the Consumer is first entitled to subsequent performance (repair or replacement). If subsequent performance fails, the Consumer may withdraw from the contract or reduce the purchase price.

Obvious defects should be reported to info@lifestylemonitors.com without delay, and in any event within two weeks of receiving the goods or discovering the defect. This notification requirement is not a precondition for asserting statutory warranty rights.

15 Limitation of liability

The Provider is liable without limitation for damage arising from injury to life, body or health, and for damage caused intentionally or through gross negligence.

In the case of slightly negligent breach of material contractual obligations (cardinal obligations), liability is limited to the foreseeable damage typical of this type of contract.

Liability under applicable product liability legislation remains unaffected.

Otherwise, liability is excluded to the extent permitted by law.

Availability of the digital services: The Provider endeavours to keep app.stresschecker.com available as continuously as possible. However, uninterrupted availability cannot be guaranteed for technical reasons. In particular, short maintenance windows, updates or unforeseeable technical faults may lead to brief restrictions, which do not constitute a defect provided they remain proportionate.

Our products are intended for:

17 Data protection

The Provider processes the Customer's personal data in accordance with the General Data Protection Regulation (GDPR) and applicable national data protection legislation.

Detailed information about the processing of personal data can be found in our Privacy Policy.

The Privacy Policy provides information in particular about:

• The nature, scope and purpose of data processing
• The legal bases for processing
• Recipients of the data (including Stripe Payments Europe Ltd., PayPal and SendGrid)
• Storage periods and deletion deadlines
• Your rights as a data subject (access, rectification, erasure, objection, data portability)

Sensitive health data: Measurement data relating to heart rate variability and stress levels is processed exclusively on the Provider's servers and is not passed on to third parties. A detailed description of the technical and organisational protective measures can be found in the Privacy Policy.

18 Dispute resolution

Participation in dispute resolution proceedings:

We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration body. We do, however, always endeavour to resolve any differences of opinion with our customers amicably.

If you have any questions or complaints, please contact our customer service in the first instance at info@lifestylemonitors.com.

19 Applicable law

The law of the Netherlands applies, to the exclusion of the UN Convention on Contracts for the International Sale of Goods (CISG).

For consumers habitually resident in another EU country, the mandatory consumer protection provisions of their country of residence remain unaffected.

Place of jurisdiction: Where the Customer is a business, a legal person under public law or a special fund under public law, the place of jurisdiction for all disputes arising from the contractual relationship is the Provider's registered office in Oosterhout (the Netherlands). In relation to consumers, the statutory places of jurisdiction apply.

20 Final provisions

The language of the contract is English.

The text of the contract is stored by the Provider. The Customer can print or save the text of the contract before submitting the order.

Severability clause: Should individual provisions of these Terms be or become invalid, this shall not affect the validity of the remaining provisions. The invalid provision shall be replaced by a valid provision which comes closest to the economic purpose of the invalid provision. The same applies to any gaps in these Terms.

Changes to these Terms: The Provider is entitled to amend these Terms with reasonable notice of at least 30 days. Where changes are made during an ongoing contractual relationship, the Customer will be informed by email in good time. If the Customer does not object to the change within 30 days, the amended version is deemed to have been accepted. This objection mechanism does not apply to changes that are to the Customer's detriment; those require express consent.

In resolving disputes, the Provider always endeavours to reach an amicable solution with the Customer.
