LLM Deck – Terms of Use

Last updated: 28 September 2026

These Terms of Use ("Terms") govern your use of the LLM Deck app ("the App"), provided by Viken Tech AS (org. no. 937 363 214), Oslo, Norway ("Viken Tech", "we", "us"). By downloading, installing or using the App you agree to these Terms. If you do not agree, do not use the App.

1. What the App is

The App is a software client that lets you send requests to OpenRouter (openrouter.ai) using your own API key. Viken Tech does not provide, host, train, operate, control or moderate any AI model, and does not provide the OpenRouter service, any model provider's service or any web search service. The App is independent and is not affiliated with, endorsed by or sponsored by OpenRouter or any model provider.

2. Who may use the App

You must be at least 18 years old, or the age of majority where you live if that is higher, and able to enter into a binding agreement. You may only use the App in compliance with all laws that apply to you.

3. Your OpenRouter account, key and costs

• You need your own OpenRouter account and API key. Your relationship with OpenRouter, the model providers and any search provider is solely between you and them, and is governed by their terms, acceptable-use policies and privacy policies, which you are responsible for reading and following.
• You are solely responsible for your API key, for keeping it secure, and for all usage and costs incurred with it, including costs caused by features such as web search, image, video or audio generation, retries and long conversations. Viken Tech does not control, see or refund any OpenRouter charges.

4. Your content and your conduct

• You are solely responsible for everything you send through the App (prompts, files, images, audio, video and any other input) and for how you use any output.
• You must not use the App to break any law; to infringe anyone's intellectual property, privacy or other rights; to create, request or distribute illegal, harmful, abusive, deceptive, discriminatory, sexually exploitative or violent content; to harass or harm anyone; to develop weapons or malware; to attempt unauthorized access to any system; or in any way that violates the policies of OpenRouter, a model provider or a search provider.
• You are responsible for having the rights and consents needed for any content or personal data you send, including personal data about other people.

5. AI output: no reliance

AI output is generated automatically by third-party models. It can be inaccurate, incomplete, out of date, biased, offensive or inappropriate, and it can appear confident while being wrong. Output is not professional advice of any kind (including medical, legal, financial, tax, psychological, safety or engineering advice). You must independently verify output before relying on it, and you use it entirely at your own risk. Viken Tech is not responsible for any output or for any decision, action or omission based on it.

6. Third-party services

The App depends on services Viken Tech does not control, including OpenRouter, model providers, search providers and Apple. Viken Tech is not responsible for their availability, performance, accuracy, pricing, security, content, data handling, retention, training practices or any change or discontinuation of them. Links and sources shown in the App lead to third-party websites that Viken Tech does not control or endorse.

7. Privacy and data handling

Viken Tech does not receive, store or process your content. Settings such as "avoid providers that store data", "zero data retention only" and similar are requests passed to OpenRouter, which alone decides whether and how to enforce them. Web search is not covered by OpenRouter's zero-data-retention routing. Do not send information you are not comfortable sharing with OpenRouter and the providers you choose. See the Privacy Policy for details.

8. Your data on your device

Chats, files and settings are stored only on your device. You are responsible for keeping backups (for example with the App's export feature or your device backups). Viken Tech is not responsible for any loss, corruption or deletion of data, including through deleting the App, erasing data, device loss or failure, or an update.

9. Pro purchase

Optional Pro features are sold as a one-time in-app purchase processed by Apple. Payments, refunds and billing are handled by Apple under Apple's terms; Viken Tech cannot issue refunds. Pro unlocks the App's features as they exist from time to time. Features may change, and Pro does not include any OpenRouter usage or credits.

10. The App is provided "as is"

To the fullest extent permitted by law, the App is provided "as is" and "as available", with all faults and without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, non-infringement, availability, security or that the App will be error-free or uninterrupted.

11. Limitation of liability

To the fullest extent permitted by law:

• Viken Tech, its owners, employees and contractors are not liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, revenue, data, goodwill, business or opportunity, or for costs of substitute services, however caused and on any theory of liability.
• Viken Tech is not liable for any damage or loss arising from AI output; your content or conduct; your API key or its use or misuse; OpenRouter charges; third-party services; web search; data loss; or unauthorized access to your device.
• Viken Tech's total aggregate liability for all claims relating to the App is limited to the amount you paid for the Pro purchase in the 12 months before the claim, or NOK 100 if you paid nothing.

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, such as liability for intent or gross negligence, for death or personal injury caused by negligence, or your mandatory rights as a consumer. Where such law applies, our liability is limited to the minimum extent permitted.

12. Indemnity

To the extent permitted by law, you will indemnify and hold harmless Viken Tech, its owners, employees and contractors from any claims, damages, losses, costs and expenses (including reasonable legal fees) arising from your content, your use of the App or of any output, your breach of these Terms or of any third-party terms, or your violation of any law or anyone's rights.

13. Changes, suspension and discontinuation

We may change these Terms and the App at any time. The current Terms are always available in the App and at viken.tech. Continuing to use the App after a change means you accept it. We may modify, suspend or discontinue the App or any feature at any time without liability. You may stop using the App at any time by deleting it.

14. Apple

These Terms are between you and Viken Tech only, not Apple. Apple is not responsible for the App or its content, and has no obligation to provide maintenance or support for it. To the maximum extent permitted by law, Apple has no warranty obligation for the App; if the App fails to conform to an applicable warranty, you may notify Apple and Apple will refund the purchase price, if any. Apple is not responsible for addressing any claims by you or third parties relating to the App, including product liability claims, claims that the App fails to meet legal or regulatory requirements, consumer protection claims, or intellectual property infringement claims. You confirm that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not on any U.S. Government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

15. General

If any part of these Terms is found invalid or unenforceable, it will be limited to the minimum extent necessary and the rest remains in full effect. Our failure to enforce a provision is not a waiver. You may not transfer these Terms; we may transfer them in connection with a reorganization or sale. These Terms, together with the Privacy Policy and Apple's Licensed Application End User License Agreement, are the entire agreement between you and Viken Tech about the App.

16. Governing law

These Terms are governed by Norwegian law. Disputes will be resolved by the Norwegian courts, with Oslo District Court (Oslo tingrett) as the agreed venue, without prejudice to any mandatory consumer protection rules or venue rights in your country of residence.
