Terms of Service
Version v4
What these Terms cover
These Terms of Service govern your use of this service. By creating an account or by using the service, you accept them. If you do not accept them, please do not use the service.
The operator of the service is named on the Imprint page.
The service is private, free and non-commercial
This is a privately operated, non-commercial project. It is made available free of charge. There is no fee, no subscription, no advertising, and nothing is sold to you.
This is not a formality. It defines what you may reasonably expect: the service is offered as a favour, not as a paid product, and it carries no promise of availability, continuity, fitness for any particular purpose, or suitability for anything you depend on. Please do not use it for anything you cannot afford to lose. Two consequences in particular follow from this, and both are set out in full below: we give no warranty, and our liability is limited to what the law permits for something provided free of charge.
Who may use the service
You must be at least 16 years old. If you use the service on behalf of an organisation, you confirm that you are authorised to do so on its behalf.
There is no entitlement to an account. We may decline registrations and may close registration entirely, at our discretion and without giving reasons.
Your account
Provide accurate information when you register, and keep your email address current, since it is how account recovery works. Keep your password and any two-factor recovery codes confidential. You are responsible for activity that takes place under your account.
If you believe your account has been accessed by someone else, revoke your sessions in your account settings and contact us using the details in the Imprint.
Acceptable use
You agree not to:
- break the law or infringe anyone else's rights when using the service;
- upload or distribute malware, or attempt to gain unauthorised access to the service, to its underlying systems, or to another person's account;
- probe, scan, overload or otherwise interfere with the availability or integrity of the service, including automated mass requests;
- circumvent authentication, rate limits, or other technical protection measures;
- use the service to send unsolicited messages or to store or distribute unlawful content;
- use the service in a way that exposes the operator to legal liability.
Content you submit
Anything you submit remains yours. We claim no ownership of it. You grant us only the simple, non-exclusive right to store, reproduce and display that content to the extent technically necessary to operate the service and to provide it back to you — nothing more, and only for as long as you keep the content on the service.
You are responsible for what you submit. You confirm that you hold the necessary rights to it and that it does not infringe the rights of third parties or applicable law.
Availability
We make no promise that the service will be available, uninterrupted, error-free, or that data stored in it will be preserved. There is no service level agreement, no guaranteed uptime and no guaranteed support.
We may change, restrict, suspend or discontinue the service or any of its features at any time, in whole or in part, and we may do so without prior notice. Where a discontinuation is planned and notice is practicable, we will give reasonable notice so that you can export your data. Your right to export your data at any time while the service is running is described in the Privacy Policy.
No warranty
The service is provided "as is" and "as available". To the extent permitted by law, we give no warranty as to its quality, fitness for a particular purpose, availability, or the accuracy or preservation of any data held in it.
Liability
Because this service is provided to you free of charge, our liability is limited to intent and gross negligence. This follows from Section 521 of the German Civil Code (BGB), applied by analogy to the gratuitous provision of services.
This limitation does not apply, and we remain liable under the ordinary statutory rules, in the following cases:
- injury to life, body or health caused by a breach of duty on our part;
- intent or gross negligence;
- fraudulent concealment of a defect, or where we have expressly assumed a guarantee;
- liability under the German Product Liability Act (Produkthaftungsgesetz);
- any other liability that cannot lawfully be excluded or limited.
Nothing in these Terms is intended to exclude or limit liability where the law does not permit it, and your mandatory statutory rights as a consumer are unaffected by these Terms.
You are responsible for keeping your own backups of anything you would not want to lose. We are not liable for data loss where it would have been avoided by a backup you could reasonably have made.
Your responsibility towards us
If you use the service unlawfully or in breach of these Terms and a third party brings a claim against us as a result, you will indemnify us against that claim and against the reasonable costs of legal defence. This does not apply where you are not responsible for the breach.
Third-party services
The service uses third-party providers, and some pages load content from them. These are named in the Privacy Policy. We have no control over their content or their own terms, and we accept no responsibility for them.
Suspension and termination
You may stop using the service at any time and delete your account yourself in your account settings. Deletion and the reversal window that follows it are described in the Privacy Policy.
We may suspend or terminate your access if you materially breach these Terms, if your use endangers the security or availability of the service, or if we are legally required to do so. Where the circumstances allow it, we will warn you first and give you an opportunity to remedy the problem. In serious cases, and where legally required, we may act immediately.
Provisions that by their nature are meant to survive termination — in particular those on liability, responsibility towards us, and governing law — continue to apply afterwards.
Changes to these Terms
We may amend these Terms, for example when the service changes or the legal position does. Every version is numbered and archived, and the version you are reading is shown at the top of this page. If we make a material change, you will be asked to review and accept the new version the next time you sign in. If you do not accept it, you can stop using the service and delete your account.
Governing law and jurisdiction
These Terms are governed by the law of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods.
If you are a consumer resident in the European Union, this choice of law does not deprive you of the protection of the mandatory provisions of the law of your country of residence, and you may bring proceedings in the courts of your place of residence.
Dispute resolution
We are neither obliged nor willing to take part in dispute resolution proceedings before a consumer arbitration board within the meaning of the German Act on Alternative Dispute Resolution in Consumer Matters (VSBG).
Severability
If any provision of these Terms is or becomes invalid, the validity of the remaining provisions is unaffected. The invalid provision is replaced by the applicable statutory rule.
