Legal

Terms of Use

End User License Agreement (EULA) for the tastewell app and this website.

1. Provider and Scope

These Terms of Use govern your use of the tastewell mobile application ("the App") and this website. The provider and your contractual partner is:

Markus Hammerschmid
Dittmanngasse 4/1, 1110 Vienna, Austria

Contact: mhammer.dev@icloud.com

By downloading or using the App, you agree to these Terms. If you do not agree, please do not use the App. This agreement is concluded between you and the provider only. Apple Inc. and Google LLC are not parties to this agreement.

2. The Service

tastewell is an app for dialling in espresso. It helps you record your coffee beans, brew recipes and shot results, and refine them over time. The App includes:

  • A bean shelf for storing beans, roasters, roast dates and tasting notes
  • Recording of dial-in values such as dose, yield, grind setting, shot time and temperature
  • Shot history and recommendations derived from your own entries
  • Equipment settings for grinders and espresso machines
  • Optional AI-generated bean cover images
  • Home screen widgets showing your active bean

Your beans, recipes, dial-in values and shot history are stored locally on your device. They are not transmitted to a server operated by the provider. Details are set out in our Privacy Policy.

3. Free Use and tastewell pro

The App can be used free of charge with a limited number of beans on your shelf. AI-generated bean covers and home screen widgets are part of the paid subscription.

A tastewell pro subscription unlocks an unlimited bean shelf, AI-generated bean covers and home screen widgets. The current scope of the free version and of tastewell pro is shown in the App before purchase and may change as the App develops.

4. Subscriptions, Billing and Cancellation

tastewell pro is offered as an auto-renewable subscription with a weekly or monthly term. The exact term and the price applicable in your country are displayed in the App before you confirm the purchase.

  • Payment is charged to your Apple App Store or Google Play account upon confirmation of purchase.
  • The subscription renews automatically at the end of each term unless it is cancelled at least 24 hours before the end of the current term.
  • The renewal charge is applied within 24 hours before the end of the current term, at the price for the applicable renewal period.
  • You can manage or cancel your subscription at any time in your App Store or Google Play account settings. Deleting the App does not cancel a subscription.
  • Existing purchases can be transferred to a new device using "Restore Purchases" on the subscription screen.
  • If a free trial is offered and you purchase a subscription before the trial ends, any unused portion of the trial is forfeited.

Billing, refunds and cancellation are handled by Apple or Google as the seller of record, not by the provider. Refund requests must therefore be submitted to Apple or Google. Statutory rights of withdrawal and consumer rights under the law of your country of residence remain unaffected.

5. AI-Generated Bean Covers

The App can generate a decorative cover image for a bean. If you use this feature, the photo you select is transmitted to the Google Gemini API for processing. Google's terms and privacy provisions apply to that processing.

  • Generated images are decorative and may deviate from your input or expectations.
  • No guarantee is given as to the availability, quality or accuracy of generated images.
  • Generation is subject to fair-use limits to keep the service available for all users. Excessive or abusive use may be throttled or restricted.
  • The provider may change or replace the AI provider used, or discontinue the feature, with reasonable notice.

6. Your Content

You retain all rights to the photos, notes and recipes you enter into the App. By using the AI cover feature, you grant the provider and the AI provider used the limited right to process the selected photo for the sole purpose of generating the requested image.

You are responsible for ensuring that you hold the necessary rights to the content you upload, and that uploading it does not infringe the rights of third parties.

7. Acceptable Use

When using the App, you agree not to:

  • Use the App for any unlawful purpose
  • Upload content that infringes the intellectual property, personality or privacy rights of others
  • Upload or generate depictions of minors, sexually explicit material, or content depicting or promoting violence, hatred, harassment or self-harm
  • Upload images of other people without their consent
  • Circumvent safety filters, usage limits or abuse protections
  • Reverse engineer, decompile or interfere with the App or its interfaces

Uploaded content may be checked by automated systems of the AI provider used. Content that violates these Terms or the policies of that provider may be rejected. In the event of repeated or serious violations, access to individual features may be restricted.

8. Availability and Changes to the App

The App is developed on an ongoing basis. Features may be added, changed or removed, and technical interruptions may occur. No specific level of availability is guaranteed. Where changes materially affect paid features, they will be announced with reasonable notice.

9. Disclaimer of Warranty

The App is provided "as is". Brewing recommendations, dial-in suggestions and calculated values are guidance based on your own entries and on general espresso practice. They are not a guarantee of a particular result. Coffee extraction depends on numerous factors outside the provider's control, including your beans, grinder, machine and water.

Mandatory statutory warranty rights under the law of your country of residence remain unaffected.

10. Limitation of Liability

To the extent permitted by law, the provider is not liable for indirect or consequential damages, or for loss of data caused by circumstances outside the provider's control. Because your data is stored locally on your device, you are responsible for backing up your device. Liability for damage caused intentionally or by gross negligence, and liability for personal injury, remain unaffected.

11. Terms Required by Apple

The following provisions apply to the App obtained through the Apple App Store:

  • Parties: This agreement is concluded between you and the provider only, not with Apple. The provider is solely responsible for the App and its content.
  • Scope of licence: The licence granted to you is a non-transferable licence to use the App on Apple-branded devices that you own or control, as permitted by the App Store Terms of Service.
  • Maintenance and support: The provider is solely responsible for maintenance and support of the App. Apple has no obligation to provide maintenance or support services.
  • Warranty: In the event of any failure of the App to conform to an applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App to you. To the maximum extent permitted by applicable law, Apple has no other warranty obligation whatsoever with respect to the App.
  • Product claims: The provider, not Apple, is responsible for addressing any claims relating to the App, including product liability claims, claims that the App fails to conform to legal or regulatory requirements, and claims arising under consumer protection or similar legislation.
  • Intellectual property: In the event of a third-party claim that the App infringes intellectual property rights, the provider, not Apple, is solely responsible for the investigation, defence, settlement and discharge of that claim.
  • Legal compliance: You represent that you are not located in a country subject to a U.S. Government embargo or designated as a terrorist-supporting country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
  • Third-party terms: You must comply with any applicable third-party terms of agreement when using the App.
  • Third-party beneficiary: Apple and Apple's subsidiaries are third-party beneficiaries of these Terms and have the right to enforce them against you.

12. Governing Law and Consumer Rights

These Terms are governed by Austrian law, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, this choice of law does not deprive you of the protection of mandatory consumer protection provisions of the country in which you have your habitual residence.

13. Changes to These Terms

These Terms may be amended, for example to reflect new features, changed third-party provider requirements or changes in the law. Material changes will be announced in the App or on this website. Continued use of the App after a change takes effect constitutes acceptance of the amended Terms.
