This is a translation for convenience. In case of doubt, the German version applies.

1Scope#

These terms apply to the use of the website winku.de (opens in a new tab), to a user account created there, to the programs offered by Winku (currently Dubster, WinkuStore, CueUp, Luvia) and to the services usable in the browser (currently Vidono, WinkuBot, Nivo, Wovia, WatchMod, Showdown, Wink). The provider is the operator named in the legal notice. Deviating terms of users do not apply.

2Services and availability#

The programs, the user account and the use of the website are free of charge. For individual services, paid access may be offered; price, term and conditions are displayed before purchase. At present no such access can be purchased. In addition, individual services facilitate paid transactions between users; details are set out in the description of the respective service (currently Vidono, see section 8a). There is no entitlement to a particular level of availability, to individual features or to continued operation. Maintenance, changes and discontinuation of individual services are possible at any time; we announce planned work on the website where feasible.

3User account#

Some features require a free account. Details provided must be accurate, credentials must be kept secret and must not be passed on. One account per person. The account can be deleted at any time without giving reasons; we may suspend or delete accounts if these terms or applicable law are breached.

3aSigning in with accounts from other providers#

Instead of an e-mail address and password, you can create and use your user account via an existing account from another provider (currently Twitch, Discord, Google, Microsoft, GitHub, GitLab, Amazon, Spotify, PayPal, Kick, Dropbox, Patreon, Epic Games, Steam, Telegram, Lichess, Roblox, Wikipedia, itch.io (opens in a new tab), X, TikTok and Minecraft (Java and Bedrock); the sign-in page shows which of them are offered). The terms of the respective provider apply in addition, and you are responsible for complying with them.
Signing in via a provider is optional and only replaces the way into the account: it creates the same Winku account with the same rights and obligations as registering with an e-mail address. Which details we receive is described in sections 15a, 15d and 15m of the privacy policy. An account is only created after you have confirmed your e-mail address with a code sent to it and accepted these terms. The details must be true; one account per person is sufficient.
We receive neither your password at the provider nor the right to do anything there on your behalf. Nothing is paid and no contract with PayPal or Amazon is concluded through signing in with them.
You can disconnect connections in your account at any time and add new ones. So that you are not locked out, at least one way to sign in always remains. If a provider suspends or deletes your account there or discontinues its sign-in interface, you can no longer sign in that way; your Winku account is not affected and remains accessible via another option or via "Forgot password" to your e-mail address. There is no entitlement to any particular provider being offered. Winku has no business relationship with the providers and is neither endorsed nor reviewed by them; their names are trademarks of their owners.

4Use of the programs#

The programs may be used free of charge, privately and commercially. The part of the programs written by Winku itself is not open source; in that respect, removing or circumventing security features (such as signature verification), altering the installation files, distributing modified versions and reselling are not permitted. Reverse engineering is permitted only to the extent mandated by law.
The programs contain third-party components under free licences, in particular under the GPL and the LGPL. For these components only the respective licence terms apply; they grant you further rights — including the right to modify and to distribute modified versions. The preceding paragraph does not restrict these rights. Which components these are, which licence they are under and where you can obtain the corresponding source code is set out at winku.de/en/licenses (opens in a new tab).

5User content#

The person posting is solely responsible for uploaded or created content (reviews, profile pictures, shared files). Unlawful, abusive or infringing content must not be posted; in particular, third-party copyright must not be infringed. Reviews and profile pictures are checked before publication. We may remove content without prior notice where a breach exists or is reasonably suspected. By posting, you grant us the simple, revocable right to display the content within the service.

6Shared files#

Files provided via the sharing function are publicly accessible through a link for as long as the link is valid (currently three days). Anyone passing on a link makes the file accessible. No personal data of third parties and no unlawful content may be shared.

7Updates and usage figures#

The programs check for updates automatically and download them; this is part of the service and also serves security. Selected programs transmit usage figures to winku.de (opens in a new tab) (such as counts of operations, error types, version states). This transmission is part of using the software and cannot be switched off. In addition the programs report anonymous figures (version, operating system, success of updates) that cannot be attributed to any person. Details on which data this is and which data is expressly not transmitted are set out in the privacy policy. Personal data of third parties (such as viewer names) is not transmitted.

8Third-party services#

Some programs work together with third-party services (e.g. Spotify, Twitch, YouTube). These require separate accounts and possibly paid subscriptions with those providers. We accept no responsibility for their availability, terms or content; their terms of use must be observed.

8kBergo — backups for PCs, NAS and mobile devices#

Bergo (bergo.winku.de (opens in a new tab), the program for Windows and macOS, the Bergo station and the Bergo app for Android and iOS) backs up data from your devices to targets you choose yourself – such as your NAS, another PC, a network share, a drive or your storage with a cloud provider –, accepts uploads from mobile devices and archives data to storage media. Use is free of charge; clause 2 applies.
The Bergo app backs up your phone’s photos, videos and, if you turn it on, other files and your contacts over your home Wi-Fi directly to the device you choose for it, or directly to your cloud; they do not pass through our servers. With “Free up space” you delete backed-up photos and videos from your phone after you have confirmed; check on your station or in your cloud beforehand that the backup is complete – as with archiving, you carry out the deletion yourself. The terms of Google Play or the Apple App Store also apply to obtaining the app; on the App Store, Apple’s standard licence agreement for apps applies as well.
Bergo is a tool. The backups are stored on your own devices and storage media; we have no access to them and keep no copy. You are responsible for choosing targets, retention and the credentials for uploads. You operate the Bergo station on your own hardware and decide which folders and media it uses. If you back up other people’s data, such as contacts or photos, you are responsible for being allowed to store it that way.
Backing up to your cloud: you can also choose your own storage with Google Drive, OneDrive, Dropbox, MEGA, pCloud, Box, S3-compatible storage or a provider with WebDAV access (such as Nextcloud) as the target; you don’t need a Winku account for this. You do need your own account with that provider. Your contract with the provider, its terms, prices and storage limits apply only between you and the provider; follow its terms, including what you may store there. Bergo transfers the files straight from your device to the provider. Credentials you enter in Bergo yourself (MEGA, S3, WebDAV) are stored by Bergo on your device only; keep them secret and, where possible, use access with as few permissions as possible. We are not a party to your contract with the provider and have no influence on whether it is available, how much space you have there, whether it suspends your account or deletes files, or whether it changes its interfaces or terms. Some providers (currently MEGA) do not issue their own approval for third-party apps; there Bergo uses the same public interface as the provider’s own apps. If your storage is full, your sign-in has expired or the provider has a problem, Bergo stops backing up there and tells you – keep an eye on these messages. If a provider changes its interface or stops working with Bergo, Bergo may no longer support that provider for a while or for good; there is no claim to support for any particular provider. What you have already backed up stays with your provider as ordinary files, even if you disconnect the cloud in Bergo or stop using Bergo. Clause 9 applies to liability.
Trademarks: Google Drive is a trademark of Google LLC; use of this trademark is subject to Google Permissions. Microsoft and OneDrive are trademarks of the Microsoft group of companies. Dropbox is a trademark of Dropbox, Inc., MEGA a trademark of Mega Limited, pCloud a trademark of pCloud AG, Box a trademark of Box, Inc., Nextcloud a registered trademark of Nextcloud GmbH; Amazon S3 is a trademark of Amazon.com (opens in a new tab), Inc. or its affiliates. Other names Bergo offers as presets (such as MagentaCloud, GMX, WEB.DE (opens in a new tab), HiDrive, Backblaze B2, Wasabi or Cloudflare R2) also belong to their respective owners. Bergo shows these names and logos only to identify the service it connects to at your request. Bergo is not a product of these companies; they have neither reviewed nor endorsed it, and there is no partnership with them.
Bergo backs up what it can read and transfer at that moment. Files that are in use, folders it cannot access, a full or switched-off target, no home network, or your operating system’s limits for apps in the background can mean that single files or whole runs are missing. Bergo shows this in the history and in notifications – keep an eye on them.
What a proper backup within the meaning of clause 9 means for Bergo: you regularly check that your backups are complete and can be restored, and you back up data that matters to you in a second, independent place as well – for example on a drive you keep separately. A single backup does not protect against every loss, for example a hardware failure, theft, fire or malware that also reaches the target. Otherwise, clause 9 applies to liability.
When archiving, Bergo can, at your request, delete files on the PC and/or in a backup after their copy on the archive medium has been verified. You carry out this deletion yourself; keep archive media safe. Every device you connect to your Winku account can access the account’s backups – only connect your own devices and remove devices you no longer use.
bergo.winku.de (opens in a new tab) only makes sure your devices can find each other. If it cannot be reached, new devices cannot be connected and backups may not run. What is already backed up stays readable on your devices as ordinary folders and files, even without Bergo. If we decide to discontinue Bergo, we will announce it on winku.de (opens in a new tab) at least three months in advance.
Passing access to third parties and attempts to circumvent the limits of the service are not permitted. We may block use if this is violated. Bergo may be restricted to individual accounts; there is no claim to access.

9Liability#

We are liable without limitation for intent and gross negligence, for injury to life, body or health, and under the German Product Liability Act. For simple negligence we are liable only for breach of a material contractual obligation whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance you may regularly rely, and limited to the foreseeable damage typical for this type of contract. As the programs are provided free of charge, the statutory reduction of liability for gifts additionally applies to them. We are liable for loss of data only to the extent that the loss would not have occurred with proper and regular data backups.

10Changes to these terms#

We may change these terms where required for legal or technical reasons or where new features require it. Changes that relate solely to a new service apply to that service once you use it; changes that only extend your rights apply upon publication. We inform account holders of all other material changes in advance by email or at the next sign-in. They apply to your account only once you expressly agree to them; we ask you for this on your next visit to winku.de (opens in a new tab). Silence or mere continued use does not constitute agreement. As long as you have not agreed, you cannot use your account or the services that require an account; publicly accessible pages such as the legal notice, privacy policy, terms and support remain available. You can agree, sign out or delete your account at any time; as use is free of charge, this costs you nothing.

11Final provisions#

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. Consumers may additionally rely on mandatory provisions of their country of residence. Should a provision be invalid, the remainder stays in force. We are neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board.
