Atmea

Terms of Use

1. Scope and provider

These Terms of Use govern the use of the mobile application “Atmea” (the “app”) and of this website. The provider is the person named in the legal notice (see https://www.atmea.app/impressum). By downloading, installing or using the app, you accept these Terms of Use. Please read the health and safety information in Section 4 carefully in particular.

2. Description of the service

Atmea is an app for breathing and apnea (breath-hold) training. Among other things, it provides breathing exercises, CO2 and O2 training tables, pyramid and emergency-duration tables, maximum attempts, recording of the BOLT score, a customisable training plan and optional training suggestions (the “Coach”). An optional function currently in beta can count diaphragm contractions via the motion sensor. All data is stored exclusively locally on your device; no user account is required, and the app works offline.

The app is a training and information tool. It is not a medical device and is not intended for the diagnosis, treatment or cure of any illness.

3. Obtaining the app and contracting party

The app is provided via the Apple App Store and Google Play. It is a paid app offered as a one-time purchase; there is no recurring fee and no subscription. The applicable price is shown in the App Store or on Google Play. The app is obtained through the respective platform; the contracting party for the acquisition – including payment, invoicing, refunds and any right of withdrawal – is Apple or Google respectively, in accordance with their respective terms. These Terms of Use apply in addition to your use of the app itself.

4. Important health and safety information

Breath-hold exercises can cause dizziness, light-headedness and, in isolated cases, fainting. Perform the exercises only in safe places – never where a brief loss of consciousness could be dangerous.

Never perform the exercises in, under or next to water, and never alone in water. Holding your breath in water can lead to a swimming-pool or shallow-water blackout and to drowning – even for experienced individuals. The exercises are intended exclusively for dry training on land.

Never hyperventilate – neither before nor during an exercise, and especially not before a breath-hold or a maximum attempt. Deliberately breathing quickly or deeply lowers the carbon-dioxide level in your blood and suppresses the natural urge to breathe. This can lead – particularly in combination with a subsequent breath-hold – to dizziness, light-headedness or fainting (hypoxic blackout) without any warning. Breathe calmly and normally before every exercise; training in Atmea is based on increased CO2 tolerance, not on hyperventilation.

Please also always observe the following rules:

  • Train lying down or sitting securely – never while standing.
  • Do not perform the exercises in a car or while driving, while cycling, or while operating machinery.
  • Do not train near bodies of water, at heights, on stairs, balconies or in other places where dizziness or fainting could lead to falls or injuries.
  • Stop the exercise immediately and breathe normally if you feel dizzy or unwell or experience pain.
  • Never force yourself beyond your limits; increase volume and intensity only slowly and listen to your body.
  • Do not hyperventilate to hold your breath longer – it does not increase safety, it increases the risk of fainting.

The exercises require a generally healthy condition. In the case of pre-existing conditions – in particular cardiovascular or respiratory diseases, high or low blood pressure, epilepsy or seizure disorders – as well as during pregnancy, perform the exercises only after prior consultation with a doctor. The app is intended for adults; minors should train only under the supervision of a responsible adult.

Use of the app and performance of the exercises are at your own responsibility and your own risk.

5. Training content and no guarantee of success

Training plans, table values and Coach suggestions are based on widely used training principles and the experiential knowledge of apnea and breathing training, not on established scientific study. They are always non-binding suggestions. No particular training or health outcome is warranted or can be guaranteed.

6. Right of use

You are granted a simple, non-exclusive and non-transferable right to use the app on the devices you use, for your own private purposes. You may not copy, modify, reverse-engineer, decompile or make the app commercially available to third parties, unless this is mandatorily permitted by law. All rights in the app, its content and its branding remain with the provider or the respective rights holders.

7. Your data and data backup

All data recorded in the app is stored exclusively locally on your device. You are responsible for backing up your data; the app provides an export and import function for this purpose. If the device is lost, reset or the app is uninstalled, locally stored data may be irretrievably lost. Details on data processing can be found in the privacy policy at https://www.atmea.app/datenschutz.

8. Availability and changes to the app

The app is provided with the care of an average provider. There is no claim to constant, uninterrupted availability or to the continued existence of particular functions. The provider may further develop the app and change or discontinue functions, insofar as this is reasonable for you.

9. Liability

Use of Atmea is at your own risk. The provider is liable without limitation for intent and gross negligence, as well as for damage arising from injury to life, body or health. In the case of simple negligence, the provider is liable only for the breach of a material contractual obligation – that is, an obligation whose fulfilment makes the proper use possible in the first place and on whose observance you may regularly rely – and limited in amount to the foreseeable damage typical for this type of contract. Otherwise, liability for simple negligence is excluded. Mandatory statutory liability, in particular under the Product Liability Act, remains unaffected.

Insofar as the provider's liability is excluded or limited under the foregoing provisions, this also applies to indirect and consequential damage, in particular the loss of data, revenue or profits. Furthermore, the provider is not liable for the loss of locally stored data insofar as the damage could have been avoided by a reasonable backup on your part.

The provider gives no warranty as to the accuracy, completeness or timeliness of the content and functions contained in the app. The app does not replace medical or therapeutic advice. No liability is accepted for the consequences of improper use or use contrary to the safety information.

10. Changes to these Terms of Use

The provider may amend these Terms of Use with effect for the future, insofar as this is necessary for objective reasons (e.g. changed functions or legal situation) and you are not thereby unreasonably disadvantaged. The current version is available at https://www.atmea.app/nutzungsbedingungen.

11. Applicable law and final provisions

The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. Mandatory consumer protection provisions of the state of your habitual residence remain unaffected. Should any provision of these Terms of Use be or become invalid, the validity of the remaining provisions remains unaffected.
