Terms of use


1. Subject Matter

A Contract between us and you governing the use of the Add-on shall come into existence upon installation of the Add-on.

2. Mode of operation

Blocks the ”seen” feature of the facebook messenger, and your friends will no longer be able to see if you read their messages.

3. Right of use

Your entitlement to use the Add-on is subject to you being above the age of 18 at the time of installation or to you obtaining the consent of a legal representative (e.g. parents).

4. Our rights and duties

In light of the available technical and operational possibilities, we shall facilitate your use of the Add-on. As such, you are granted a temporally and geographically unlimited, and non-exclusive right to use the Add-on subject to the following conditions. We reserve the right to modify or undertake technical changes to our service without giving prior notice, so far as such action can be considered reasonable to Users. We reserve the right to cease operation of the Add-on for an indefinite period or entirely. Furthermore, we are entitled, irrespective of any other statutory rights, to exclude Users from the use of the Add-on.

5. Your rights and duties

The permitted use of the Add-on entails its installation and use in accordance with its intended purpose. You are not entitled to lease the Add-on or to sub-licence it in any other form; or to communicate or make the Add-on available to the public, whether by wire or wireless means. Any modifications to the Add-on which exceed the intended purpose require our prior consent. This includes, for example, amendments to the source code, the integrated commentary texts; or adaptation to suit a new user interface. You are prohibited from exploiting bugs and/or errors in the Add-on’s programming for your own purposes. Known bugs and/or errors should be reported to us as quickly as possible via the contact form.

6. Operational capability

We shall strive, on the basis of the technical possibilities, to enable the constant operation of the Add-ons. Due to maintenance, security and capacity reasons, brief disruptions and temporary limitations to the Add-on cannot be excluded. By accepting the Terms, you explicitly agree that, in order to ensure the full scale operational capability of the add-ons’ security updates for the respective browser, we will make an initial evaluation of the updates before installing them for you. The security updates’ evaluation shall take place within a reasonable time period, but without delay upon release. You further acknowledge that we cannot guarantee an unlimited operation capability of the add-on.

7. Updates and additional functionalities

We shall endeavour to keep the Add-on up-to-date through regular updates. You have the possibility of preventing updates from being installed by deactivating the automatic update function in your browser’s add-on manager. The updates close security gaps, extend the Add-on’s functional features and supplement other Add-on applications. The updates are offered to users free of charge. You therefore authorise us to use the update function to realise financing opportunities through the conversion of existing links into affiliate links.

8. Indemnity

You shall indemnify us against all claims brought by third parties as a result of you violating third party rights or breaching statutory provisions through the use of the Add-on. In this event, you shall reimburse all our legal costs, including legal representation costs. Any additional claims to compensation we may have remain unaffected.

9. Funding

To finance the provision of this free service, search results on search engines are being highlighted through a third party service.

10. Liability and security

Our liability for minor negligent breaches shall be limited to such damage as is foreseeable and arises directly and naturally from the contract, unless the breach causes damage to life, limb or health; is a breach of guarantee; or affects the rights arising from the Product Liability Act. The limitation on liability shall also not apply to breaches of duties, the fulfilment of which is necessary for the proper performance of the contract and the compliance with which you can generally rely on. The same applies to breaches of duty by our agents. We shall use all reasonable endeavours to keep the Add-on free from known computer viruses. As such, you acknowledge however that for technical reasons we cannot guarantee complete freedom from viruses. No claims can be brought against us for end equipment becoming infected with computer viruses as a result of using the Add-on. This includes claims for the replacement of lost data. We shall not be liable for disruptions to the Add-on, such as failure of the server or the software, which result from technical or legal circumstances that are beyond our control.
