Liability for content
As a service provider, I am responsible for my own content on these pages in accordance with general legislation. The content has been created with the greatest possible care; however, I cannot guarantee its accuracy, completeness or timeliness. Pursuant to §§ 8 to 10 DDG, I as a service provider am nevertheless not obliged to monitor transmitted or stored third-party information or to investigate circumstances that indicate illegal activity. Obligations to remove or block the use of information under general legislation remain unaffected. However, liability in this respect is only possible from the point in time at which I become aware of a specific infringement. If I become aware of any such infringements, I will remove the content in question immediately.
Liability for links
My website may contain links to external third-party websites over whose content I have no influence. I therefore cannot accept any liability for such third-party content. The respective provider or operator of the linked pages is always responsible for their content. The linked pages were checked for possible legal violations at the time of linking; no unlawful content was discernible at that time. However, permanent monitoring of the content of linked pages is not reasonable without concrete evidence of a legal violation. If I become aware of any legal violations, I will remove such links immediately.
Copyright
The content and works created by the operator on these pages are subject to German copyright law. Reproduction, adaptation, distribution and any kind of exploitation outside the limits of copyright law require the written consent of the respective author or creator. Insofar as the content on this page was not created by the operator, the copyrights of third parties are respected and marked as such.
Terms of use of the app
ProjectTimeTracker provides features for recording and analysing project and working times for informational and organisational purposes. The times recorded in the app are based on user input.
ProjectTimeTracker is not a system for the statutory recording of working time within the meaning of § 16 (2) of the German Working Hours Act (ArbZG) and replaces neither such a system nor a company's accounting and record-retention obligations. Users are solely responsible for the accuracy and completeness of the recorded data and for its use in billing, invoicing or payroll accounting. I recommend backing up and reviewing important data regularly.
ProjectTimeTracker is an independent product and is not affiliated with the providers of any third-party services mentioned. Trademarks mentioned belong to their respective owners.
Free version and Premium subscription
ProjectTimeTracker can be used free of charge. In the free version, the number of time entries is limited to 250 per year; cloud backup and synchronisation across multiple devices are included. The Premium subscription removes this limit and unlocks the extended data export. The current feature set and prices are listed on the pricing page.
The Premium subscription is purchased exclusively within the app and processed via the user's Apple account. The contracting party for the purchase of the subscription is therefore exclusively Apple (Apple Distribution International Ltd., Hollyhill Industrial Estate, Hollyhill, Cork, Ireland), not the operator of this website. Apple's Media Services Terms and Conditions, including the licence terms contained therein (Standard EULA), apply to the purchase.
The subscription renews automatically for the selected term (monthly or yearly) unless it is cancelled at least 24 hours before the end of the current period. Cancellation is carried out in the device settings under Apple ID → Subscriptions. Billing is handled through the Apple account. After the subscription ends, the recorded data is retained and the app can continue to be used within the scope of the free version.
Right of withdrawal: As the subscription contract is concluded with Apple, any right of withdrawal and any refunds are governed exclusively by Apple's terms. Refund requests must therefore be addressed directly to Apple. The operator of this website cannot issue refunds.
Availability, data backup and discontinuation
The app is provided free of charge or on the terms stated above, without any assurance of a particular level of availability. There is no entitlement to uninterrupted access to the synchronisation and backup functions. Maintenance work, technical faults or circumstances beyond my control may lead to temporary restrictions.
Cloud storage does not replace your own data backup. Users remain responsible for exporting and reviewing important data regularly. Liability for data loss exists only within the limits of statutory provisions.
I reserve the right to modify or discontinue the service or individual features. Any planned discontinuation of the synchronisation service will be announced with reasonable notice in the app or on this website so that stored data can be exported.
Dispute resolution
I am neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board.
