Terms of Service

StuhlgangGo is a diary in which you record your own observations according to the Bristol stool scale – comparable to a notebook that counts along. The app is expressly not a health app and not a medical device.

The app does not evaluate your entries, does not interpret them and offers no recommendations of any kind. The summaries it displays – history, trend chart, type distribution and the summary in the report – are purely descriptive presentations of the information you entered yourself and reflect nothing beyond what you logged.

Accordingly, your records and the report generated from them are not a basis for decisions that go beyond your own self-observation. What you use your records for is entirely your decision.

Use of StuhlgangGo requires a minimum age of 16. Minors may use the app – in particular the paid feature – only with the consent of a parent or guardian. By using the app you confirm that you meet these requirements.

Logging entries, the history, the trend chart and all settings including the app lock are free of charge and ad-free on a permanent basis. There is no entitlement to the feature set of the free version remaining unchanged.

The export function (PDF report and CSV raw data) is the paid Pro feature. It is unlocked permanently through a single one-time in-app purchase. This is expressly not a subscription – there are no recurring charges and no cancellation is required.

Purchases are processed exclusively through the respective app store (Apple App Store or Google Play Store). The store operator is your contractual partner for payment processing; its payment and usage terms apply in addition. The unlock status is tied to the store account used for the purchase and can be transferred to further devices via "Restore purchases".

For digital content made available immediately after purchase, the following applies: by unlocking the export function you expressly agree that we begin performing the contract before the 14-day withdrawal period expires. You acknowledge that your statutory right of withdrawal lapses upon full performance of the contract (Sec. 356(5) German Civil Code). Mandatory consumer protection rights remain unaffected.

Refunds: since all payments are processed through the Apple App Store or Google Play Store, refunds can only be issued by the respective store operator in accordance with its refund policy. We have no access to your payment data and cannot refund payments directly. Please direct refund requests to:

• Apple App Store: via reportaproblem.apple.com or Apple's support channels.
• Google Play Store: via the "Orders & subscriptions" section of your Google account or Google Play support.

Any statutory warranty and refund claims against us remain unaffected by the store policies.

StuhlgangGo works entirely offline: logging, history, trend chart and export all function without an internet connection. A connection is only needed for the in-app purchase, restoring it, and opening external links such as these pages.

For the purchase and the verification of the unlock status we depend on third-party services (Apple, Google, RevenueCat) whose availability is outside our control. Temporary outages or maintenance of these services do not constitute a defect as long as the app's core functions remain usable. Your mandatory statutory rights as a consumer remain unaffected.

All entries are stored exclusively on your device. There is no user account, no cloud synchronisation and no server-side backup of your data.

This means: if your device is lost, damaged or reset, if you switch to a new device, or if you uninstall the app, your entries are irretrievably lost. The app cannot restore them. Backing up your data – for example via the export function or your operating system's device backup – is your responsibility alone.

You share exported reports yourself; we are not responsible for their further use. Please bear in mind that these files contain your personal records.

Details on the collection, processing and use of your data can be found in our separate app privacy policy for StuhlgangGo.

We grant you a simple, non-transferable right to use the app on devices under your control for private purposes. In particular, reverse engineering, modifying or redistributing the app, as well as circumventing the unlock of paid features, are prohibited unless expressly permitted by law.

The content you record belongs to you. We claim no rights to it and – since it never leaves your device – have no access to it either.

SD Nightshift Studio is liable without limitation for intent and gross negligence. For slight negligence we are liable only in the event of a breach of material contractual obligations (cardinal obligations) whose fulfilment is essential to the proper performance of the contract. In such cases liability is limited to the foreseeable damage typical for this type of contract. Liability under the German Product Liability Act and for injury to life, body or health remains unaffected.

We accept no liability for decisions you make on the basis of the records displayed in the app – the app only ever reproduces your own input and makes no statements beyond it (see section 1). For data loss, our liability under the above provisions is limited to the damage that would have occurred had you backed up your data properly and regularly (see section 6).

The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. Where the user is a consumer, mandatory statutory consumer protection provisions of the country of their habitual residence remain unaffected.

Consumer dispute resolution: we are neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board.
