Terms and Conditions

1. Scope of application

These Terms and Conditions govern the use of the web application "PostureShift" (hereinafter "App"), accessible at app.postureshift.info and provided by Daniel Schwarz, Meergässle 8, 89180 Berghülen (hereinafter "Provider"). By using the App, you accept these Terms and Conditions.

2. Description of services

The App supports timed switching between seated, floor, and standing positions based on a freely configurable posture rotation with timer and reminder functionality. The App can be used purely locally on the user's own device without a user account, or with a free user account for cross-device synchronisation of rotations and settings.

The App is made available to the user free of charge. There is currently no paid additional offering.

PostureShift is a general movement and reminder tool and does not replace medical advice, diagnosis, or treatment. If you have any health concerns, in particular existing back problems, please consult an appropriate professional.

3. Registration and user account

Cross-device synchronisation requires providing a valid email address; no password is required (login via magic link). The user is obliged to provide truthful information. The user may request deletion of their account and the associated stored data at any time by informing the Provider informally.

4. Availability

The Provider endeavours to provide the App as free of interruption as possible, but does not guarantee constant availability. Maintenance work, technical faults, or outages at third-party providers used (e.g. hosting services) may lead to temporary limitations of synchronisation. The App's local, on-device functionality remains fundamentally unaffected by this.

5. Advertising

The landing page and the App may be co-financed by displaying advertising (Google AdSense). Advertising is only displayed if the user has expressly consented via the cookie consent banner. If declined, no advertising is shown; the App's core functions remain unaffected.

6. Liability

The Provider is liable without limitation for intent and gross negligence, as well as under the German Product Liability Act. For slight negligence, the Provider is liable only in the event of a breach of a material contractual obligation (cardinal obligation), the fulfilment of which makes proper use of the App possible in the first place and on whose observance the user may regularly rely; in this case, liability is limited to the foreseeable damage typical for this type of contract.

The Provider is not liable for the loss of locally stored data (e.g. in the event of loss or resetting of the device), provided no user account with synchronisation was used.

The Provider assumes no liability for health consequences arising from the application of the postures and exercises suggested in the App; use is at the user's own responsibility.

7. Changes to these Terms and Conditions

The Provider reserves the right to amend these Terms and Conditions with effect for the future, where this is necessary to adapt to changed legal or technical circumstances. Users will be informed of material changes in a suitable manner (e.g. a notice within the App).

8. Final provisions

The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG). Should individual provisions of these Terms and Conditions be or become invalid, the validity of the remaining provisions shall remain unaffected.
