Terms of Use

This is a convenience translation. In case of doubt, the German version (Nutzungsbedingungen) prevails.

These terms govern the use of Wirio. They are deliberately kept short and readable. By creating an account you agree to them.

1. Provider and scope

The provider is Fabian Meyer, Weissensteinweg 10, 5330 Bad Zurzach, Switzerland (the “provider”). These terms apply to everyone using Wirio (“users”). Conflicting terms of users do not apply.

2. What the service is

Wirio is a messaging service with end-to-end encryption. Depending on its current state it offers one-to-one and group chats, voice and video calls, status posts and a classified ads section. It can be used in a browser, as a mobile app and as a program for Windows, Mac and Linux; all three access the same service. The desktop program keeps itself up to date.

Use is free of charge. There is no entitlement to availability, to any particular feature or to its continued existence. The provider may change, limit or discontinue features; for substantial limitations he will give notice where reasonable.

3. Accounts

• Use requires a minimum age of 16 years. Younger persons may use Wirio only with the consent of a legal guardian.
• An account is personal. Credentials must be kept secret and must not be passed on.
• Anyone suspecting unauthorised access to their account must change their password immediately.
• As a rule, one account per person is intended. Accounts must not be created automatically in larger numbers.

4. Rules of use

The following is prohibited in particular:

• distributing unlawful content, in particular content infringing criminal law, personality rights, copyright, trade mark law or competition law;
• distributing other people's works without the necessary rights – such as images, music, videos or texts;
• harassment, threats, insults, incitement and calls for violence;
• fraud, deception about one's identity and pretending to be connected to other persons or companies;
• unsolicited advertising, chain letters and bulk messages;
• distributing malware and attempts to disrupt, overload or gain unauthorised access to the service;
• automated extraction of data and use through software not provided by the provider, insofar as operation is impaired;
• passing on content from private conversations to third parties where this infringes personality rights.

5. Your own content

Users are responsible for everything distributed through their account. By posting content they confirm that they hold the necessary rights.

The provider acquires no rights of use of his own beyond what is technically necessary. Granted is merely the right to store and transmit content and to display it to the intended recipients – limited to the duration of use and the purpose of the service.

Should third parties approach the provider because of posted content, the responsible person shall indemnify the provider against justified claims, including reasonable costs of legal defence. This does not apply insofar as the person is not responsible for the infringement.

6. Classified ads

In the marketplace, users post their own ads. Contracts about offered goods are concluded exclusively between the parties involved. The provider is not involved, does not become a party and gives no warranty as to the accuracy, lawfulness or feasibility of offers. Disputes arising from such deals are to be settled between those involved.

Ad content is visible to others and therefore technically not end-to-end encrypted; the service states this. The chat about an ad is encrypted like any other chat.

6a. Services

Services may also be offered in the marketplace – such as trades, repairs, removals, care or tuition. Here too, any engagement is concluded exclusively between the parties involved; the provider does not act as an intermediary, does not verify qualifications and is not liable for how the work is carried out.

Anyone offering services is responsible for holding the necessary permits, qualifications and insurance and for meeting their tax and social security obligations. For activities requiring authorisation – such as electrical, gas and plumbing installation, nursing care or passenger transport – the applicable statutory requirements apply.

The following must not be offered, regardless of whether they are lawful in a given place:

• sexual services of any kind, escort services with a sexual connotation, and arranging or brokering them;
• procuring persons for purposes with a sexual connotation;
• medical treatment without the required licence;
• financial, legal or tax advice without the required authorisation;
• activities designed to evade taxes or social contributions.

Excluding sexual services is a decision by the provider for this service and applies even where such activities are legally permitted. Corresponding ads will be removed and the account may be suspended.

7. Reports and measures

Content and behaviour can be reported within the service. The provider reviews reports and may remove content, restrict features or suspend an account in case of breaches of these terms or of applicable law – for serious breaches also without prior notice. The provider will choose the mildest suitable measure and will state reasons for a suspension on request.

The provider is not obliged to monitor content in general. Due to end-to-end encryption, reviewing content without a report is not even technically possible for him.

8. Encryption, key loss and backups

Private keys remain exclusively on users' devices. The provider does not know them and cannot restore them. If they are lost – through a change of device, clearing browser data or a defect – encrypted content is irretrievably lost. There is no claim to restoration.

The service does not replace your own backups. Users are responsible for securing important content themselves; the service offers a way to back up the key.

8a. Disappearing messages and link previews

A chat can be set so that new messages disappear after 24 hours, 7 days or 90 days. What is deleted are the copies on the server and in the app. This does not amount to protection against redistribution: recipients can copy, photograph or otherwise save content beforehand. The setting applies to the whole chat, can be changed by anyone involved and affects future messages only.

If a message contains a link, the service retrieves the linked page in order to produce a preview. No liability is accepted for the content or availability of third-party pages; the preview merely reproduces what the page states about itself. Details on data processing are set out in the Privacy Policy.

9. Liability

The provider is liable without limitation for intent and gross negligence as well as for injury to life, body and health.

Otherwise liability – in particular for slight negligence, loss of profit, loss of data and indirect damage – is excluded to the extent permitted by law. As the service is provided free of charge, no warranty can be given for uninterrupted availability or freedom from errors.

The provider is not liable for content distributed by users. He removes unlawful content as soon as he becomes aware of it.

Mandatory statutory liability provisions remain unaffected.

10. Changes to these terms

If the scope of the service or the legal situation changes, the provider may adapt these terms. Substantial changes will be announced within the service. Anyone not agreeing to the amended version may delete their account at any time; continued use after the notice counts as agreement.

11. Termination

Users may delete their account at any time in the settings. The provider may terminate the relationship giving 14 days' notice, and without notice in case of breaches of these terms. When an account is deleted, the associated data is removed unless a statutory retention obligation applies.

12. Final provisions

Swiss law applies, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods. Place of jurisdiction is Zurzach, Switzerland, unless a mandatory statutory venue applies – in particular, consumers retain the venue at their place of residence.

Should any provision of these terms be invalid, the remaining provisions remain unaffected. The invalid provision shall be replaced by the permissible rule that comes closest to its purpose.
