Terms

These General Terms and Conditions (“Terms”) govern the use of the Tevyon platform and all associated means of access: website and Studio, application programming interface (API), MCP server, command line and connectors in third-party applications (together the “Service”).

The contracting party is Tevyon, Zurich, Switzerland (“Tevyon”, “we”). The contact details are in the Legal Notice.

The Usage Policy and the notes on AI Labeling form part of these Terms. How we process personal data is explained in the Privacy Policy. Deviating terms set by users apply only if we agree to them in writing. For companies with their own contract (e.g. Enterprise), that contract takes precedence.

• Job: a single request to a model, e.g. an image, a video or an upscale.
• Inputs: everything you give a job, such as prompts, settings, reference images, videos and audio tracks.
• Results: what a job produces.
• Credits: the unit of account of the Service. Every job costs a specific number of credits.
• Draft and final: an inexpensive preview with a fast model and the later final result with the same settings.
• Preset: a prepared sequence of one or more jobs with fixed prompts and settings.
• Workspace: a shared account for a team with members, shared credits and folders.
• Models: the AI models of third-party makers (e.g. Seedance, Kling, Veo, Nano Banana, GPT Image) that Tevyon offers in the Service.

You need an account for the Service. You sign in with your email address and a one-time code. You must be at least 18 years old and have legal capacity. Anyone who opens an account for a company confirms that they are authorized to represent it.

Keep your details up to date and your access secret; this also applies to API keys and tokens. You are liable for actions taken through your account, unless you are not at fault for the misuse. If you notice misuse, report it immediately to support@tevyon.ai.

Tevyon provides you with models from various makers through a common interface and API, supplemented by its own features such as Presets, draft and final, credits and workspaces. The Service always shows which models, resolutions, lengths and features are currently available.

The models are continually changed, replaced or discontinued by their makers. We may therefore add, replace or remove models. If a model that was essential to you is discontinued during a running plan and there is no equivalent replacement, you can cancel the plan immediately and get back the unused part pro rata.

Every job runs through the prompt skill of the selected model: we prepare your prompt for this model before the job starts. Your own text stays in your history. Through the API, you can switch the preparation off.

AI results are not predictable. We owe the professional execution of the job with the selected model, not a particular result. Similar inputs can lead to similar results for other users. Features labeled “Beta” or “Preview” may change or be removed again.

Price before the start. Before every job, the Service shows you the number of credits it costs. This price applies to the job. A change in credit prices applies only to jobs that start afterwards.

Director. With the fast and balanced language models, the Director is free within the daily quota. Messages to the most powerful language models cost credits. Before sending, you see the usual and the maximum price. We charge what the message actually used, never more than the maximum price. If you stop a message, the usual price applies. If it fails on our side, it costs nothing.

Charging in three steps. When a job starts, we reserve the credits. If the job succeeds, we charge them. If it fails, times out or moderation blocks the result, we return the reserved credits in full. If you received a result you don’t like, that is not a failure.

Validity.

• Purchased credit packs and free credits do not expire as long as your account exists, not even after the plan is canceled.
• Credits from a plan are valid until the end of the billing period for which they were credited. Whatever you do not use by then expires.
• If a job fails only after the end of the period its plan credits come from, we return them to you as credits that do not expire.

Credits from the plan are used first, then purchased and free credits. Credits have no cash value, are not paid out and are not transferable, except within your workspace.

All prices in Swiss francs are final prices.

Plans run monthly and renew automatically for another month until you cancel. You can cancel at any time in your account with a few clicks. The cancellation takes effect at the end of the current period; until then, the plan remains usable.

Payments are processed by a payment service provider. We do not store complete card details. You authorize us to collect the amounts when due from the payment method on file. If a payment fails, we inform you and try again for 14 days. If it remains outstanding, the plan ends afterwards. You get a month’s plan credits as soon as it is paid; purchased credits remain yours in any case.

We notify you by email of price increases for existing plans at least 30 days before they take effect. Until then, you can cancel as of the end of the current period. If you do not cancel, the new price applies from the next period. If you switch to a higher plan, it applies immediately and is billed pro rata: for the pro rata amount, you receive credits at the new plan’s price, valid until the end of the current period. A switch to a lower plan applies from the next period.

If a payment is refunded or charged back through your bank or card issuer, we deduct the credits bought with it again pro rata. If you have already used them, the amount remains outstanding: we offset it against your next credits, and until it is settled, you cannot start new jobs. If a chargeback is decided in our favor, we restore the credits. If there is a problem, contact us first; we can usually solve it faster.

If you are a consumer residing in the European Union, you can withdraw from a contract for a plan or a credit pack within 14 days of its conclusion without giving any reason. A message to support@tevyon.ai is sufficient. We refund the payment within 14 days to the original payment method.

When you buy, you can request that we perform immediately. If you expressly confirm at the same time that you lose your right of withdrawal when performance begins, it expires as soon as you start the first job with purchased credits. We send you the confirmation by email.

Swiss law provides no statutory right of withdrawal for online purchases. This section therefore does not apply to customers outside the EU, unless mandatory law of their country of residence provides for it.

Your inputs remain yours. You warrant that

1. you hold the necessary rights to all inputs, in particular copyrights, trademark rights and related rights;
2. for every recognizable person in images, videos or audio tracks, you have their consent to use them in this way, or another justification, such as an overriding public interest;
3. you do not upload images of minors, unless you have parental authority and the use is harmless;
4. your inputs and their use do not violate the law or the Usage Policy.

If third parties claim that your inputs or your use of the results infringe their rights, you support us in defending against the claim. If you are at fault for the infringement, you compensate us for the damage and the reasonable costs of legal defense.

To the extent that rights to results arise with us, we transfer them to you in full upon creation. You may use, edit and publish the results privately and commercially, even after the contract ends. This applies in every plan, including free credits.

Please note: as things stand today, purely machine-generated results are often not protected by copyright in Switzerland and the EU. We therefore cannot warrant that you can prohibit third parties from using similar content. Nor do we warrant that results do not infringe the rights of third parties, for example if they resemble a well-known character, brand or person. Check results before publishing them commercially.

For individual models, the usage rules of their makers also apply. Where this is the case, we refer to them in the model overview.

You allow us to store, copy, technically convert and transmit your inputs and results to the selected model, to the extent this is necessary for the Service. This also includes moderation, security and handling your requests. This permission is non-exclusive and royalty-free, and it ends when you delete the content or your account. Copies that we must keep for legal reasons are excepted.

We do not train any AI models of our own on your inputs or results, and we do not pass them on to anyone for training purposes. We show results publicly, for example in a gallery or in advertising, only if you expressly approve it. You can revoke an approval at any time with effect for the future.

If you share a result in the Community, that is such an approval, and only for the Community. The Community is public: everyone sees the result there, even without an account, and search engines can find it, together with your profile (name, handle, description, profile picture), the model and, unless you switch it off, your prompt. Signed-in users can mark it with “Like” and follow your profile; publicly, we show only the numbers. You allow us to show the result there, and other users to reuse your prompt for their own jobs. The permission applies as long as you share the result; if you delete your profile, everything shared becomes private again. We cannot take back what others have already seen or saved. Share only what you hold the rights to, and recognizable persons only with their consent; this also applies to your profile picture. We may take reported results and profiles out of the Community pending review; you see the reason in your profile.

The Usage Policy applies to the content of your inputs and results. We and the makers of the models check inputs and results automatically. A blocked job costs you no credits.

In the event of a violation, we may, depending on its severity, remove content, restrict features, temporarily suspend the account or terminate the contract without notice for good cause. We inform you of the measure and the reason, unless the law or ongoing investigations prohibit this. You can appeal within 30 days. A human reviews the appeal. We report material depicting the sexual abuse of children to the competent authorities.

Whoever opens a workspace is its owner. The owner invites members, assigns roles and manages the shared credits and billing. The owner ensures that all members comply with these Terms and is liable for their use of the shared credits.

Content in shared folders is visible to the authorized members. If a member leaves the workspace, the content created there stays with the workspace. If a workspace processes personal data of third parties, we conclude a data processing agreement on request.

The API, MCP server and command line use the same job interface and the same credits as the Studio. The same prices and rules apply. We may limit the number of requests to keep the Service stable, and we state the limits in the documentation.

Keys and tokens are personal. Do not pass them on and do not build them into publicly visible code. You may build the Service into your own products, but you may not resell it as your own offering under another name unless we have agreed to this in writing.

If you use Tevyon through a third-party application, for example Claude by Anthropic, that application’s own terms also apply to it. There is no partnership between Tevyon and Anthropic. What the third-party application does with your data is not our responsibility.

We operate the Service with due care but do not owe any particular availability, unless a separate contract provides for one. We announce maintenance where possible. If a maker’s models fail, the Service may be restricted. We return the credits of running jobs that fail as a result.

We continue to develop the Service and may change features. If a change materially restricts a plan, the special right of cancellation under section 4 applies.

We are liable without limitation for damage we cause intentionally or through gross negligence, and for personal injury. For slight negligence, we are liable only for breaches of essential contractual obligations and only for the foreseeable, typical damage. Liability is then limited per calendar year to the amounts you paid us in the twelve months before the event causing the damage, but to no less than CHF 100.

In cases of slight negligence, we are not liable for lost profits, loss of data on your systems or consequential damage. Keep important results on your own systems as well. Mandatory statutory liability, for example under the Swiss Product Liability Act or the mandatory consumer law of your country of residence, remains reserved. These rules also apply to our auxiliary persons.

The contract runs for an indefinite period. You can end it at any time by deleting your account. A running plan then ends at the end of the period. Upon deletion, unused credits expire; we show you beforehand how many there are. We can terminate the contract with 30 days’ notice where there is no plan, as of the end of the period where there is one, and without notice for good cause.

If we terminate without you having given us a reason, we refund purchased, unused credits pro rata. After the contract ends, you have 30 days to download your results. After that, we delete content and account according to the periods in the Privacy Policy.

We may change these Terms, for example because of new laws, new features or changed terms of the model makers. We notify you of material changes by email at least 30 days in advance and show you the differences. If you do not agree, you can cancel until the changes take effect, and we refund the unused part of a paid plan pro rata. If you do not cancel, the new Terms apply from the stated date. We point this out expressly in the notice. We send you earlier versions on request.

Swiss law applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG) and the conflict-of-law rules. The place of jurisdiction is Zurich. Consumers can additionally sue at their place of residence and be sued there. Mandatory protective provisions of their country of residence remain applicable.

Before you go to court, please write to us. Most concerns can be resolved quickly this way. We do not take part in dispute resolution proceedings before a consumer arbitration board.

If a provision is invalid, the rest remains valid. It is replaced by the provision that comes closest to its purpose and is legally permissible. The German version is authoritative; translations are for information purposes. We may transfer the contract to a company that takes over the Service. We inform you beforehand, and in that case you can cancel.
