End User License Agreement (EULA) for "Fairhour"

Provider: Delil Ayin Product: Fairhour (German: Fairhour), version 1.0 Version of this document: 1 October 2026

§ 1 Subject Matter and Parties

1.1 This End User License Agreement (the "Agreement") is concluded between Delil Ayin, Schmiedeweg 6, 3048 Worblaufen, Switzerland, Switzerland (the "Provider") and you as the user (the "Customer").

1.2 The subject matter of this Agreement is the provision of the software "Fairhour" (the "Software") for use against a one-time fee, and the grant of the usage rights described in § 2.

1.3 The Software is an application for Microsoft Windows 11. It records locally on the device which program is in the foreground, how long it was used and how often it was started. Optionally, time limits can be set, reports generated, and websites and programs blocked.

1.4 The scope of functionality follows from the product description valid at the time of purchase at fairhour.ch or in the store listing. That description is authoritative; no features beyond it are owed.

1.5 By installing, copying or using the Software, the Customer accepts this Agreement. Anyone who does not accept it must not install or use the Software.

1.6 If the Software is obtained through a distribution partner (for example the Microsoft Store), that partner's terms apply in addition. In case of conflict, the distribution partner's terms prevail for the purchase transaction itself; this Agreement governs the use of the Software.

§ 2 Grant of Usage Rights

2.1 Upon full payment, the Provider grants the Customer a simple, non-exclusive, non-transferable and non-sublicensable right to install and use the Software as intended.

2.2 The license is granted for an unlimited period for the major version purchased, unless stated otherwise at the time of purchase.

2.3 The Customer may install the Software on up to 3 (three) devices owned by or under the sole control of the Customer. Simultaneous use by several persons on several devices under the same license is permitted only within this device count.

2.4 The Customer may create one backup copy of the installation files for personal use.

2.5 Use in companies, public authorities, schools or other organisations requires a separate license. Terms are available at support@fairhour.ch.

2.6 All rights not expressly granted remain with the Provider. The Customer does not acquire ownership of the Software, but only the usage rights described above.

§ 3 Prohibited Use

3.1 The Customer must not reverse engineer, decompile or disassemble the Software, nor convert the object code back into any other code form. Mandatory statutory rights, in particular those aimed at establishing interoperability, remain reserved.

3.2 The Customer must not modify the Software, combine it with other programs into a new product, or create derivative works from it.

3.3 The Customer must not rent, lease, lend the Software or operate it as a service for third parties.

3.4 Reselling, transferring, publishing or trading license keys is prohibited. The same applies to acquiring license keys from unauthorised sources. The Provider is entitled to block keys that demonstrably originate from unauthorised sources or have been sold more than once.

3.5 The Customer must not circumvent, remove or disable copy protection, activation or license verification mechanisms. Copyright and manufacturer notices must not be removed or altered.

3.6 The Customer must not use the Software to manipulate other software or to undermine the security mechanisms of third-party systems.

3.7 Further transfer of the Software is permitted only if the Customer permanently and completely deletes their own copy, retains no copies, and the acquirer accepts this Agreement. For licenses tied to a store account, transfer is technically and legally excluded.

§ 4 Permitted Use and Protection of Other Users

4.1 The Software is intended as a tool for monitoring one's own screen time and for transparent use within a family.

4.2 The Software must not be used for the covert surveillance of other persons. In particular, any use aimed at monitoring the behaviour of another person without their knowledge is prohibited, whether that person is a partner, family member, flatmate, employee or third party.

4.3 Anyone using the Software on a device that is shared with other persons must inform those persons beforehand. The information must be given before recording starts and must cover at least: that recording takes place, what is recorded, who can view the data, and how long the data is retained.

4.4 The Customer is solely responsible for complying with the rules applicable to their use. This includes in particular data protection law, the protection of personality rights, and, where the Software is used in relation to employees, employment law and the information and consultation duties applicable there. Covert monitoring of employee conduct and performance is generally not permitted under Swiss employment law.

4.5 When the parental module is used, § 4.3 applies accordingly to children and adolescents. Further guidance is set out in the document "Guidance for Parents".

4.6 The Provider has no technical access to the recorded data and cannot verify compliance with these rules. The Customer shall indemnify the Provider against third-party claims arising from the Customer's breach of § 4.

4.7 The Software deliberately contains no hidden mode. The notification area icon in the taskbar remains visible at all times during operation. A breach of § 4 constitutes a material breach of contract and entitles the Provider to extraordinary termination under § 9.3.

§ 5 Operation, Data and Privacy

5.1 The Software stores all recorded data exclusively locally on the Customer's device, by default in an SQLite file in the directory %LOCALAPPDATA%\PcZeit.

5.2 No usage data is transmitted to the Provider or to third parties. The Software contains no telemetry. A connection to a server is only established if the Customer expressly pairs the optional parent app with the device; the data transmitted in that case is described in the "Parent App" supplement to the Privacy Policy. Without this pairing, the Software remains entirely local.

5.3 The Software does not record keystrokes and does not capture screenshots.

5.4 Recording of window titles is disabled by default and can be deliberately enabled by the Customer. Window titles may contain sensitive information such as document names, search terms or addresses of visited websites. The Customer is solely responsible for this decision.

5.5 The Customer is responsible for backing up their data and for protecting the device and the database file. The Provider cannot recover lost data.

5.6 Details on data processing are set out in the privacy policy at fairhour.ch.

§ 6 Parental Module and Blocking Functions

6.1 The parental module is optional and protected by a password set by the Customer. The Provider does not know this password and cannot reset it. If the password is lost, access to the module may be permanently lost.

6.2 The blocker can block websites through an entry in the system hosts file and close programs by terminating the associated process.

6.3 The Customer acknowledges that terminating processes may cause data loss in the affected programs, and that changes to the hosts file affect the network behaviour of the device. The Customer uses these functions at their own risk.

6.4 The Provider does not warrant that blocks cannot be circumvented. The blocking functions are an aid, not technically watertight protection. They replace neither supervision nor parenting.

6.5 The blocker must not be applied to devices over which the Customer has no authority.

6.6 In the parent module the Customer may enable a filtering DNS service of a third party (CleanBrowsing or Cloudflare) for the device. The Software then enters that service's addresses in the network settings. The respective third party alone is responsible for the filtering decisions, availability and data processing of that service; its terms of use and privacy policy apply. The Provider of Fairhour does not operate this service and gives no warranty for it. When the feature is disabled, the Software restores the previous network settings.

§ 7 Warranty

7.1 The Provider warrants that, when used as intended, the Software substantially conforms to the product description valid at the time of purchase.

7.2 The Customer acknowledges that, according to the state of the art, software cannot be created entirely free of defects. Insignificant deviations from the product description do not constitute a defect.

7.3 The Provider fulfils its warranty obligations by remedying the defect, as a rule by providing an update or a workaround. If remediation fails twice within a reasonable period, the Customer may withdraw from the contract and request a refund of the purchase price.

7.4 The warranty period is 12 months from purchase. In relation to consumers, at least the statutory period applies; mandatory statutory rights remain unaffected.

7.5 No warranty is given for defects attributable to: a) use outside the stated system requirements; b) modifications to the Software by the Customer or third parties; c) interference by other software, security programs or changes to the operating system; d) improper operation or missing backups; e) incorrect time or system settings of the device.

7.6 The Provider does not warrant that the recorded times are exact in every case. Measurements may be affected by operating system behaviour, standby states, virtual desktops or third-party software. The data is not intended for billing, evidentiary or employment law purposes.

7.7 The Customer must report apparent defects to support@fairhour.ch within a reasonable period after discovery.

§ 8 Liability

8.1 The Provider is liable without limitation for damage resulting from injury to life, body or health, and in all other cases in which a limitation of liability is not legally permissible.

8.2 Under Swiss law, liability for unlawful intent and for gross negligence cannot be excluded in advance (Art. 100 para. 1 of the Swiss Code of Obligations). Such liability remains in full.

8.3 Otherwise, the Provider is liable for slight negligence only in the event of a breach of material contractual obligations, and limited to the foreseeable damage typical for this type of contract. In such cases liability is capped at the amount paid by the Customer for the Software.

8.4 Within the scope of § 8.3, liability is excluded in particular for lost profit, data loss, business interruption, indirect damage and consequential damage.

8.5 The Provider is not liable for damage arising because the Customer uses the Software contrary to § 4, because blocking functions are circumvented, or because the Customer takes decisions based on the recorded data.

8.6 The above limitations of liability also apply for the benefit of the Provider's auxiliary persons and vicarious agents.

8.7 Mandatory rights under product liability law remain unaffected.

§ 9 Term and Termination

9.1 The Agreement begins when the Customer accepts it and runs for an indefinite period.

9.2 The Customer may end the Agreement at any time by ceasing use, uninstalling the Software and deleting all copies. This does not give rise to any claim to a refund.

9.3 The Provider may terminate the Agreement without notice for cause, in particular in the event of a significant breach of § 3 or § 4.

9.4 Upon termination, the usage rights expire. The Customer must uninstall the Software and delete all copies. The Customer's locally stored usage data remains on their device and can be deleted by the Customer.

§ 10 Updates, Support and Further Development

10.1 The Provider may make updates available to fix defects and improve the Software. A claim to updates exists insofar as they are required to remedy defects under § 7, and otherwise only where expressly promised at the time of purchase.

10.2 Updates within the purchased major version are free of charge. An upgrade fee may be charged for new major versions.

10.3 The Provider may further develop the scope of functionality, provided the contractually owed core benefit is preserved. If a material function is permanently removed, the Customer may terminate the Agreement.

10.4 The Provider may discontinue maintenance of the Software with 6 months prior notice. The existing license remains in force in that case; the Software may continue to be used.

10.5 Support is provided by email to support@fairhour.ch, in German and English, under the conditions stated at fairhour.ch. No specific response time is promised unless otherwise agreed.

§ 11 Third-Party Rights and Open Source Components

11.1 The Software may contain third-party components subject to their own license terms. Those terms prevail over this Agreement for the components concerned.

11.2 An overview of the components used and their licenses is available in the Software under Settings → About and at fairhour.ch.

§ 12 Changes to this Agreement

12.1 The Provider may amend this Agreement at any time for future purchases.

12.2 For licenses already acquired, the version accepted at the time of purchase applies. Changes take effect only if the Customer agrees to them or if they are strictly necessary to comply with changed legal requirements.

§ 13 Export Control and Sanctions

13.1 The Customer must comply with applicable export, import and sanctions regulations.

13.2 The Customer confirms that they are not listed on any relevant sanctions list and will not export the Software to countries subject to an export ban.

§ 14 Governing Law and Place of Jurisdiction

14.1 This Agreement is governed exclusively by Swiss law, excluding its conflict of laws rules and excluding the United Nations Convention on Contracts for the International Sale of Goods (CISG).

14.2 The exclusive place of jurisdiction is the Provider's registered office in 3048 Worblaufen, Switzerland.

14.3 Mandatory places of jurisdiction and mandatory consumer protection provisions of the state in which a consumer has their habitual residence remain reserved.

§ 15 Severability

15.1 Should individual provisions of this Agreement be or become wholly or partly invalid or unenforceable, the validity of the remaining provisions shall remain unaffected.

15.2 The parties shall replace the invalid provision with a valid provision that comes closest to its economic purpose. The same applies to gaps in the Agreement.

15.3 Amendments and supplements to this Agreement require text form. This also applies to any waiver of this form requirement.
