Terms of Use
For the Glutkern mobile app. Last updated: July 2026.
1. Scope and provider
These terms of use apply to the use of the mobile app Glutkern (the „App"), provided byChristoph Bimmer, Undeostr. 37, 85661 Forstinning, Germany („we"). The terms of the respective app store through which you obtain the App apply in addition.
2. Description of the service
Glutkern is an application for managing your own grill fleet with matching recipes, core temperatures, timers, guides and a photo logbook. Its core functionality works fully offline on your device. Individual additional content (e.g. premium recipes and extended cooking profiles) may in future be unlocked as an optional, one-time in-app purchase. There is no claim to specific, unchanged features or to uninterrupted availability; we continuously develop the App further.
3. Purchase and processing via the app stores
Downloading the App and any in-app purchases are handled exclusively via the respective app store (Apple App Store, Google Play). The contractual partner for the purchase is the respective store operator; their terms and payment conditions apply. The price shown in the store at the time of purchase is decisive. Paid additional content is offered as a one-time purchase and remains unlocked permanently - this is not a subscription.
4. Right of withdrawal for digital content
An in-app purchase is digital content. By purchasing, you expressly agree that the unlock takes effect immediately and confirm that your statutory right of withdrawal expires once performance begins. Refunds are governed by, and must be handled through, the respective store operator.
5. Rights of use
We grant you a simple, non-transferable and non-sublicensable right to use the App on the devices you control for your own purposes. Modifying, decompiling or redistributing the App beyond the scope provided by the store is not permitted. In addition, the end-user license terms of the respective app store apply (e.g. Apple's standard EULA for licensed applications).
6. Availability and changes
We may update, extend, restrict or discontinue the App and its features where this is reasonable for you (e.g. for technical or legal reasons). Purchases you have already unlocked remain unaffected as far as technically possible.
7. Core temperatures and grilling notes
Core temperatures, doneness levels and other grilling notes in the App and in the grill knowledge section are editable reference values and not a guarantee of a specific result or of food safety. You are responsible for safe preparation, for the safe handling of fire, gas and devices, and for complying with food safety regulations.
8. Warranty and liability
The App is provided with due care. We are liable without limitation for intent and gross negligence and for injury to life, body or health. In the case of simple negligence, we are only liable for the breach of a material contractual obligation (cardinal obligation) and limited to the foreseeable damage typical for the contract. Otherwise, liability is excluded. Mandatory statutory liability, for example under product liability law, remains unaffected. You remain responsible for regularly backing up your data (e.g. via the backup function).
9. Data protection
Information on how we handle data can be found in our privacy policy.
10. 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 your country of residence remain unaffected. Should any provision be invalid, the validity of the remaining provisions remains unaffected. For questions, please contact [email protected].
