1.2 The provider is TTI – Technologie-Transfer-Initiative GmbH an der Universität Stuttgart / TGU Detach, Nobelstraße 15, D-70569 Stuttgart, Germany, represented by Valerie Grappendorf (hereinafter "Provider" or "Detach"). Further provider information (commercial register, VAT ID, etc.) can be found in the legal notice of TTI GmbH (https://www.tti-stuttgart.de/impressum).
1.3 Insofar as these Terms and Conditions refer to consumers or entrepreneurs, the respective statutory definitions under German law shall apply.
1.4 Deviating or conflicting terms and conditions of users shall not apply unless expressly agreed otherwise.
1.5 By downloading, installing, or using the App, the user accepts these Detach Terms and Conditions as well as the additionally incorporated General Terms and Conditions of TTI GmbH as binding.
1.6 For users residing in the United States, the additional provisions in Section 14 ("Additional Terms for U.S. Users") apply and, in the event of a conflict, prevail over the other provisions of these Terms and Conditions.
1.7 These Terms and Conditions are available in German and English. For users residing in the United States, the English version, including Section 14, is authoritative. For all other users, the German version shall prevail in the event of discrepancies between the language versions.
2.1 The Detach App provides digital functions that enable users to monitor and individually restrict their smartphone usage.
2.2 In particular, the App provides functions for the temporal or functional restriction of selected apps ("blockers").
2.3 Detach is not a medical or therapeutic service. The use of the App does not replace medical or psychological advice or treatment. No success is guaranteed.
3.1 The use of the App is generally only permitted for persons aged 16 and over. For users under the age of 16, the consent of the legal guardians is required.
3.2 The App is currently available for iOS devices and is provided via the Apple App Store. Additional platforms may be added in the future.
3.3 The use of certain functions may require registration.
3.4 The Provider is not obliged to technically verify the age of users or the existence of consent by legal guardians. Responsibility for this lies with the user or their legal guardians.
4.1 The App can generally be used free of charge.
4.2 In the free version, one blocker is available to the user.
4.3 The use of additional blockers as well as further functions is only possible within the scope of a paid subscription or a separately offered service.

5.1 Paid services may be offered as subscriptions with various terms (e.g. monthly, six-month, or annual subscriptions).
5.2 Paid services offered within the App to end users are billed via the respective App Store used. In addition, the terms of use and payment conditions of the respective App Store operator apply.
5.3 For separately offered services, in particular for business customers or within the framework of individual agreements, deviating payment and billing methods may be agreed.
5.4 Prices are displayed within the App or in the respective offer. For users in the European Union and Switzerland, prices include the applicable statutory value-added tax, unless expressly agreed otherwise. For users in the United States, prices are stated exclusive of taxes; any applicable sales, use, or similar taxes may be added at checkout and collected by the respective App Store operator.
5.5 For minor users, the conclusion of paid services requires the consent of the legal guardians.
5.6 The contract for paid services is concluded between the user and the Provider. The respective App Store acts solely as a payment processor and is not a contractual partner of the user.
5.7 Where an introductory or promotional price is offered, it applies only for the period stated in the respective offer. After expiry of the introductory period, the subscription renews at the regular price displayed at the time of purchase, unless the subscription is cancelled in accordance with Section 6.

7.1 Consumers with their habitual residence in the European Union or the European Economic Area are generally entitled to the statutory right of withdrawal when concluding a paid contract.
7.2 In the case of contracts for digital content, the right of withdrawal expires as soon as the consumer has expressly agreed that the performance of the contract begins before the expiry of the withdrawal period and has confirmed that they thereby lose their right of withdrawal.
7.3 The consent pursuant to paragraph 2 is given as part of the purchase process via the Apple App Store.
7.4 Entrepreneurs are not entitled to a statutory right of withdrawal.
7.5 The statutory right of withdrawal under this Section 7 does not apply to users residing in the United States. For such users, refund requests are governed by the terms of the respective App Store operator (see Section 14.6).
8.1 The Provider grants the user a non-exclusive, non-transferable right, limited to the duration of the user agreement, to use the App for their own purposes.
8.2 Any transfer, reproduction, modification or commercial use of the App or its content is not permitted unless legally permitted or expressly agreed.
9.1 Users may not misuse the App or use it in a manner that impairs the functionality of the App.
9.2 The App is used on the device used by the user. The user is responsible for ensuring that their device is protected at all times against access by unauthorized third parties.
9.3 If, in the future, certain functions require registration or the use of access data, the user is obliged to treat such data confidentially and protect it from access by third parties.
9.4 If the App in the future provides functions for interaction between users or for the publication of content, users are obliged to comply with applicable laws and the rights of third parties when using such functions. The Provider is entitled to remove content or restrict access to such functions if this is necessary to safeguard legitimate interests.
10.1 The Provider strives to ensure that the App is available as uninterruptedly as possible, but does not guarantee permanent availability.
10.2 The Provider reserves the right to adapt, further develop or discontinue functions of the App, provided that no essential contractual obligations are impaired. This also applies to the introduction of new functions, including interactive or community-based functions.
11.1 The use of the App is at the user's own risk.
11.2 The Provider shall be liable without limitation in cases of intent and gross negligence, as well as for damages resulting from injury to life, body or health.
11.3 In the event of slightly negligent breaches of essential contractual obligations (so-called "cardinal obligations"), liability shall be limited to the foreseeable damage typical for the contract at the time of conclusion of the contract. Essential contractual obligations are those whose fulfillment makes the proper execution of the contract possible in the first place and on whose compliance the user may regularly rely.
11.4 In all other respects, liability is excluded to the extent permitted by law. Mandatory consumer protection provisions remain unaffected.
11.5 The above limitations of liability shall also apply in favor of the legal representatives, employees and agents of the Provider.
11.6 For users residing in the United States, the warranty disclaimers and limitations of liability in Section 14 apply in addition to and, in the event of a conflict, instead of this Section 11.
Information on the processing of personal data is contained in the privacy policy, which is available within the App as well as on the website under the section "Data Protection".
13.1 The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. For users residing in the United States, this choice of law is subject to the provisions of Section 14.
13.2 For consumers, no exclusive place of jurisdiction applies. For entrepreneurs, the place of jurisdiction shall be the registered office of the Provider (Stuttgart/Germany).
13.3 For consumers with their habitual residence in another Member State of the European Union, the mandatory consumer protection provisions of that state shall remain unaffected.
13.4 For consumers with their habitual residence in Switzerland, the mandatory provisions of Swiss law as well as any places of jurisdiction shall remain unaffected.

13.6 The Provider is neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board.
The following provisions apply exclusively to users who reside in the United States. In the event of a conflict with the other provisions of these Terms and Conditions, this Section 14 prevails.
These Terms and Conditions are governed by the law of the Federal Republic of Germany, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods; however, this choice of law does not deprive you of the protection of mandatory consumer protection provisions of the law of the U.S. state in which you reside. Notwithstanding the foregoing, Section 14.4 (Arbitration) is governed by the U.S. Federal Arbitration Act.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WITHOUT LIMITATION IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. THE PROVIDER DOES NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, OR THAT THE USE OF THE APP WILL ACHIEVE ANY PARTICULAR RESULT (INCLUDING ANY REDUCTION IN SCREEN TIME). SOME STATES DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SOME OR ALL OF THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE PROVIDER AND ITS LEGAL REPRESENTATIVES, EMPLOYEES, AND AGENTS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, USE, OR GOODWILL, ARISING OUT OF OR IN CONNECTION WITH THE USE OF OR INABILITY TO USE THE APP, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE PROVIDER'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE APP SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID TO THE PROVIDER FOR THE APP IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) FIFTY U.S. DOLLARS (USD 50). NOTHING IN THIS SECTION EXCLUDES OR LIMITS LIABILITY FOR INTENT (WILLFUL MISCONDUCT), GROSS NEGLIGENCE, FRAUD, OR FOR DEATH OR PERSONAL INJURY CAUSED BY NEGLIGENCE, OR ANY OTHER LIABILITY THAT CANNOT BE EXCLUDED OR LIMITED UNDER APPLICABLE LAW. SOME STATES DO NOT ALLOW THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES, SO SOME OR ALL OF THE ABOVE LIMITATIONS MAY NOT APPLY TO YOU.
PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS, INCLUDING YOUR RIGHT TO FILE A LAWSUIT IN COURT.
(a) Informal Resolution First. Before initiating arbitration, you and the Provider agree to first attempt to resolve any dispute informally. You may send a written notice of dispute to info@detach-app.de, including your name, a description of the dispute, and the relief requested. The Provider will do the same by contacting you at the email address you have provided, if any. If the dispute is not resolved within sixty (60) days of receipt of the notice, either party may commence arbitration.
(b) Agreement to Arbitrate. You and the Provider agree that any dispute, claim, or controversy arising out of or relating to these Terms and Conditions or the use of the App shall be resolved by binding arbitration on an individual basis, administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules then in effect. The arbitration shall be conducted in the English language. To the extent an in-person hearing is required, it shall take place in the county of your residence in the United States or another mutually agreed location; the arbitration may also be conducted by videoconference or on the basis of written submissions where the AAA rules so permit. Payment of filing, administration, and arbitrator fees shall be governed by the AAA rules. The arbitrator's award shall be final and binding and may be entered as a judgment in any court of competent jurisdiction.
(c) Class Action Waiver. YOU AND THE PROVIDER AGREE THAT EACH PARTY MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. The arbitrator may not consolidate more than one person's claims and may not preside over any form of class or representative proceeding. If this class action waiver is found to be unenforceable with respect to a particular claim, then Section 14.4 shall be void as to that claim, which shall proceed in court, while the remainder of this Section 14.4 remains in effect for all other claims.
(d) Exceptions. Either party may (i) bring an individual claim in small claims court in the county of your residence, provided the claim qualifies for small claims jurisdiction, and (ii) seek injunctive or other equitable relief in a court of competent jurisdiction to protect its intellectual property rights.
(e) Opt-Out Right. You may opt out of this arbitration agreement and class action waiver within thirty (30) days of first accepting these Terms and Conditions by sending an email to info@detach-app.de with the subject line "Arbitration Opt-Out", stating your name and the email address or account identifier associated with your use of the App. Opting out of arbitration will not affect any other provision of these Terms and Conditions.
(f) Survival. This Section 14.4 survives the termination of the user agreement.
The App is not directed to children under the age of 13, and the Provider does not knowingly collect personal information from children under 13. The age requirements set out in Section 3 (16 years of age, or consent of legal guardians) apply to U.S. users as well.
Purchases made through the Apple App Store are subject to Apple's payment and refund terms. Refund requests for purchases made via the App Store must be submitted to Apple through the mechanisms provided by Apple (e.g., reportaproblem.apple.com). The Provider has no control over and assumes no responsibility for Apple's refund decisions.
If any provision of this Section 14 is held to be invalid or unenforceable, the remaining provisions of this Section 14 and of these Terms and Conditions shall remain in full force and effect, except as expressly provided in Section 14.4(c).
