Terms of Service

These Terms of Service (“Terms”) form a binding contract between you and Stivio (“Stivio”, “we”, “us”). Stivio is operated as an independent sole proprietorship; “Stivio” refers to that sole proprietorship and is the legal counterparty under these Terms. The Terms govern your access to and use of stivio.ai, our APIs, and all related features (the “Service”). Please read them carefully. By creating an account, signing in, or otherwise using the Service, you accept these Terms and our Privacy Policy and Refund Policy.

If you are accepting these Terms on behalf of an organization, you represent that you have authority to bind that organization, in which case “you” refers to that organization.

1. Acceptance of these Terms

You accept these Terms by (a) clicking an “I agree” button, (b) creating an account, or (c) using the Service. If you do not agree, do not use the Service.

2. Definitions

• Account — your individual user account on the Service.
• Credits — the unit of metered usage of the Service.
• Plan Credits — credits granted under a Subscription that expire at the end of each billing cycle.
• Top-up Credits — credits purchased as a one-time pack that do not expire.
• Free Credits — credits we grant for free (e.g. signup bonus, promotions).
• Subscription — a recurring monthly or yearly paid plan.
• Inputs — anything you upload or submit (motion prompts and the photos you upload as first / end frames).
• Outputs — the generated video files (MP4) returned to you.
• AI Provider — KIE.ai, the upstream video-model providers whose models you select (currently the Kling / Kuaishou, Seedance / ByteDance, Wan / Alibaba, and Hailuo / MiniMax families), OpenAI (content moderation), and any other model host we use.

3. The Service

The Service generates video clips from a photo you upload and an optional motion prompt, using third-party AI Providers. You choose the video model, clip length, resolution, aspect ratio, and sound setting; the resulting MP4 is delivered to your account history and can be shared via a link. We are not the developer of the underlying models and our delivery depends on the AI Providers' availability. The Service is a technical generation tool: we do not review, clear, license, or approve videos for any particular use.

4. Eligibility

• You must be at least 13 years old to create an account.
• You must be at least 18 to purchase a paid Subscription or one-time pack.
• You may not use the Service if you are located in a jurisdiction subject to a US, UN, EU, or UK comprehensive embargo (e.g. Cuba, Iran, North Korea, Syria, the Crimea/DNR/LNR regions of Ukraine).
• You may not use the Service if you are listed on any sanctions list maintained by the US Treasury OFAC, UN Security Council, EU, or UK HMT, or are owned 50% or more by parties so listed.
• You may not use the Service if we have previously terminated your account, unless we expressly authorize you to return.

5. Your account

• Sign-in is via Google OAuth. We do not store passwords.
• You must keep your Google account secure. You are responsible for all activity on your Stivio account.
• You may have only one personal account. Team plans, when offered, allow multiple seats per the plan's terms.
• You must promptly notify us at hello@stivio.ai if you suspect unauthorized access to your account.
• You may delete your account at any time by emailing us.

6. Acceptable Use Policy

6.1 Permitted use

You may use the Service for personal, professional, educational, and commercial purposes within the limits of your plan, including generating Outputs for social media content, advertising, product listings, client work, and personal projects.

6.2 Prohibited content

You may not use the Service to generate, upload, request, or distribute:

• Child sexual abuse material (CSAM), or any sexualized depiction of minors. We report all such content to the National Center for Missing & Exploited Children (NCMEC) and to law enforcement.
• Sexually explicit content, pornography, or fetish content involving identifiable people without explicit consent.
• Content that promotes violence, terrorism, self-harm, suicide, or eating disorders.
• Content that incites hatred, harassment, or discrimination on the basis of race, ethnicity, religion, gender, gender identity, sexual orientation, disability, or other protected characteristics.
• Doxxing or content that discloses personal information of identifiable people without their consent.
• Election manipulation content, false government communications, or deepfake imagery of identifiable real people.
• Counterfeit official documents (IDs, passports, currency, certificates).
• Material that infringes copyright, trademark, trade dress, design rights, rights of publicity, or other rights of any third party — including brand logos, protected characters, celebrity likenesses, and band or sports-team marks. The Service does not check Outputs for infringement; compliance is your responsibility (§10.2).
• Personal data of others (names, addresses, photos) without their consent or another lawful basis.

6.3 Prohibited conduct

You may not:

• Reverse-engineer, decompile, scrape, or otherwise attempt to extract source code or training data from the Service or any AI Provider.
• Run automated requests, bots, or load tests against the Service except through APIs we expressly publish.
• Bypass or attempt to bypass our rate limits, signup-credit restrictions, content moderation, fingerprint, or IP throttle.
• Resell, sublicense, or redistribute Credits, raw API access, or reseller accounts at scale without our written permission. Selling Outputs you generated is allowed, subject to §10.2 and §11.
• Impersonate Stivio, our staff, or another user.
• Interfere with the Service's integrity or performance, e.g. via DDoS, malware, or exploitation of vulnerabilities. Responsible security disclosure to hello@stivio.ai is welcome.
• Use the Service in violation of export control or sanctions laws.

6.4 Enforcement

Submitted prompts are screened by an automated content moderator before generation. We may also review specific generations on report or as part of trust-and-safety operations. We may, in our sole discretion, take any of the following actions for a violation, without prior notice:

• Refuse to generate a particular Output;
• Suspend access to specific features;
• Suspend your Account pending review;
• Permanently terminate your Account and all associated Credits;
• Report to law enforcement where required by law.

7. Credits

• Credits are charged per second of generated video, at a rate that depends on the video model, resolution, and sound setting you select (as of the effective date: standard models cost 2 Credits per second — 10 Credits for a 5-second clip — and the flagship tier costs 6 Credits per second, with higher resolutions and sound charged as shown in the studio). The exact Credit cost of your selection is always displayed on the Generate button before you submit, and per-model rates appear on the Pricing page. Rates are subject to change with notice.
• Plan Credits are reset (overwritten, not stacked) at the start of each billing cycle and expire at the end of that cycle.
• Top-up Credits never expire.
• Spending order: Plan Credits first (since they expire), then Top-up Credits.
• Free Credits (signup bonus, promo) have no cash value and are non-transferable.
• Failed generations are automatically refunded — each Credit returns to the bucket it was deducted from. See Refund Policy.
• If your account balance is insufficient, generation requests will be rejected with a clear error.

8. Subscriptions, billing & auto-renewal

• Subscriptions are billed in advance, in USD, by Stripe, on the calendar day matching your initial purchase.
• Auto-renewal. Your Subscription automatically renews at the end of each billing cycle until you cancel.
• Cancellation. You can cancel any time from the Stripe Customer Portal accessible via your Dashboard. Cancellation takes effect at the end of the current cycle; you keep access and Plan Credits until then.
• Yearly plans.Yearly plans are charged once for the full year, and the full year's Credits are granted upfront at purchase as non-expiring Top-up Credits — there is no monthly cap or monthly drip. See the Refund Policy for the pro-rata refund window.
• Failed payments. Stripe retries failed payments per its dunning settings. If recovery fails, your Subscription will be downgraded to free.

9. Tax, fees & pricing changes

• Prices are exclusive of tax. Stripe Tax may add VAT, GST, or sales tax based on your billing address.
• You are responsible for any other taxes or duties applicable in your jurisdiction.
• We may change prices for new Subscriptions at any time. For existing Subscriptions, we will give at least 30 days' notice before any price increase takes effect at the next renewal. You may cancel before the increase applies.

10. Intellectual property

10.1 Your Inputs

You retain all rights you have in your Inputs. You grant Stivio and its sub-processors a worldwide, non-exclusive, royalty-free license to host, copy, transmit, transform, and process your Inputs solely to deliver the Service to you, prevent abuse, and comply with law. This license terminates when you delete the Input or your Account, subject to retention required for legal or backup purposes.

10.2 Generated Outputs — your rights and your responsibility

Subject to your compliance with these Terms and the AI Providers' underlying terms, to the extent we hold any rights in the Outputs we generate for you, we assign those rights to you on creation. You may use Outputs for personal, professional, and commercial purposes, including in advertising, social media content, and client work.

Stivio provides a technical generation service only. You are solely and fully responsible for the legality of the videos you request, generate, download, and publish — including ensuring they do not infringe any third party's copyright, trademark, or rights of publicity or likeness (this matters especially for videos of identifiable people), and that they comply with the content policies of any platform you publish them to. We do not review, clear, or license Outputs, we make no search of prior works, and we provide no warranty of non-infringement or of fitness for publication on any platform (see §15). AI models can produce outputs that resemble existing protected works even from an innocuous prompt — review every Output before commercial use. Claims arising from your use of Outputs are your responsibility under §17 (Indemnification).

10.3 Aggregated & anonymized data

We may use aggregated, anonymized, or de-identified data derived from Inputs and Outputs (such as prompt-length distributions, error rates, average resolution mix) to operate, secure, and improve the Service. Such data does not identify you and is not subject to confidentiality obligations to you. We do not use your Inputs or Outputs to train Stivio-owned models.

10.4 Our IP

The Service, including the Stivio brand, logo, design, code, prompt templates, style presets, and documentation, is owned by us or our licensors and protected by intellectual property law. Except for the limited rights expressly granted to you, we reserve all rights. You may not remove copyright notices or claim ownership of any portion of the Service.

11. AI output disclaimer — important

Outputs are produced by generative AI video models from your photo and prompt. By nature of the technology:

• Results vary run to run.The same photo and prompt can produce different motion each time, and similar inputs from other users can produce similar videos. Outputs may also resemble existing footage, characters, or styles present in the models' training data.
• Fidelity is not guaranteed. Faces, hands, physics, and any text visible in the scene may render imperfectly or drift over the course of the clip; models may add, remove, or alter details of your photo. Review every frame that matters before publishing.
• Prompt adherence is approximate. The model interprets your motion description; specific timings, camera moves, or actions may not be followed exactly.
• Platform acceptance is not guaranteed. Social and advertising platforms apply their own content, disclosure, and AI-labeling policies; an Output we generate may still be rejected, labeled, or taken down by them, and some jurisdictions require AI-generated media to be disclosed as such.

Stivio disclaims all liability for any consequence arising from commercial use of an Output without your own review, including lost sales, platform suspensions, ad-account restrictions, and third-party claims.

12. Third-party services

The Service integrates Google (sign-in), Stripe (payments), and AI Providers (KIE.ai, OpenAI, and the upstream video-model providers listed in §2). Your use of those integrations is also governed by their respective terms and privacy policies. We are not responsible for changes, outages, or actions of those third-party services.

13. DMCA / copyright complaints

If you believe content on the Service infringes your copyright, send a notice to hello@stivio.ai with the subject line [DMCA] containing:

1. A physical or electronic signature of the copyright owner or authorized agent.
2. Identification of the copyrighted work claimed to be infringed.
3. Identification of the allegedly infringing material and information reasonably sufficient for us to locate it (URL, generation ID, timestamp).
4. Your contact information (name, address, phone, email).
5. A statement that you have a good-faith belief that the use is not authorized by the copyright owner, its agent, or the law.
6. A statement, under penalty of perjury, that the information in the notification is accurate and that you are the owner or authorized to act on the owner's behalf.

We respond to valid notices by removing the infringing content and notifying the user who created it. Users may submit a counter-notice with the equivalent statutory information. We terminate accounts of users who are repeat infringers.

14. Privacy

Our handling of personal data is described in our Privacy Policy, which is incorporated into these Terms by reference.

15. Disclaimers

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE AND ALL OUTPUTS ARE PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, AND UNINTERRUPTED OPERATION. WE DO NOT WARRANT THAT OUTPUTS WILL MEET YOUR EXPECTATIONS, BE FREE OF ERROR, OR REFLECT ANY REAL-WORLD STRUCTURE OR LEGAL REQUIREMENT.

16. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, STIVIO AND ITS OFFICERS, EMPLOYEES, AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR SUBSTITUTE-SERVICE COSTS, EVEN IF ADVISED OF THE POSSIBILITY.

OUR TOTAL AGGREGATE LIABILITY FOR ANY CLAIM ARISING FROM OR RELATED TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID US IN THE 12 MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) USD 100.

Some jurisdictions do not allow exclusion of certain warranties or limitations on certain damages; in those jurisdictions our liability is limited to the maximum extent permitted by law.

17. Indemnification

You agree to defend, indemnify, and hold harmless Stivio and its affiliates, officers, employees, and agents from any third-party claim, damage, loss, or expense (including reasonable attorneys' fees) arising from (a) your Inputs, (b) your use of Outputs, (c) your violation of these Terms or applicable law, or (d) your infringement of any third-party right.

18. Suspension & termination

• We may suspend or terminate your Account immediately for violation of these Terms or for unlawful or abusive use.
• We may terminate inactive Accounts (no sign-in for 24 consecutive months) after giving you 30 days' email notice.
• You may terminate at any time by deleting your Account from the Dashboard or by emailing us.

19. Effect of termination

On termination: your access to the Service ends; unused Plan Credits are forfeit; Top-up Credits are forfeit unless refundable under the Refund Policy; we delete your data per the retention schedule in our Privacy Policy. Sections that by their nature should survive (definitions, IP, disclaimers, liability, indemnification, dispute resolution, governing law, general provisions) will survive termination.

20. Modifications to the Service

We may add, remove, change, or deprecate features at any time. We will give reasonable notice of material removals or breaking changes that affect paid users.

21. Modifications to these Terms

We may update these Terms from time to time. For material changes we will notify you at least 30 days in advance via email or in-app banner. Continued use of the Service after the new Terms take effect constitutes acceptance. If you object to a change, you may terminate your Account before the change takes effect and request a pro-rata refund per the Refund Policy.

22. Force majeure

We are not liable for delay or failure to perform caused by events beyond our reasonable control, including natural disasters, war, terrorism, civil unrest, government action, labor disputes, internet outages, third-party service failures (including AI Providers, Stripe, Google, Vercel, Neon), or pandemics.

23. Governing law

These Terms are governed by the laws of the State of Delaware, USA, excluding its conflict-of-law rules. The UN Convention on Contracts for the International Sale of Goods does not apply. Where mandatory consumer-protection law of your country of residence grants you additional rights, those rights are not waived.

24. Dispute resolution & arbitration

24.1 Informal resolution first

Before filing any claim, you and Stivio agree to try in good faith to resolve the dispute informally for at least 60 days by emailing hello@stivio.aiwith a description of the dispute and the relief you seek.

24.2 Binding individual arbitration

If the dispute is not resolved within 60 days, you and Stivio agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Service will be resolved by binding individual arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, with the seat of arbitration in Delaware, USA. Judgment on the award may be entered in any court of competent jurisdiction.

24.3 Class-action waiver

YOU AND STIVIO AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, OR REPRESENTATIVE ACTION. The arbitrator may not consolidate claims of more than one person.

24.4 30-day opt-out

You may opt out of §24.2 and §24.3 by emailing hello@stivio.aiwithin 30 days of first accepting these Terms with the subject line [Arbitration opt-out] and including your full name and the email associated with your Account. Opting out does not affect any other part of these Terms.

24.5 Carve-outs

Either party may bring an individual action in small-claims court if eligible. Either party may seek injunctive relief in court for actual or threatened infringement of intellectual-property rights or unauthorized access. Nothing in this section prevents you from contacting a government agency.

24.6 EU / UK consumers

If you are a consumer resident in the EU, the United Kingdom, or Switzerland, the arbitration provisions in §24.2 and §24.3 apply only to the extent permitted by mandatory law in your country. You retain the right to bring claims in your local courts. The European Commission's Online Dispute Resolution platform is available at ec.europa.eu/consumers/odr; we are not contractually obligated to use it.

25. General provisions

• Severability. If any provision of these Terms is held invalid or unenforceable, the remainder will remain in full force.
• No waiver. Our failure to enforce a provision is not a waiver of that provision.
• Assignment. You may not assign these Terms without our written consent. We may assign these Terms to an affiliate or in connection with a merger, sale of assets, or reorganization.
• Notices. We give notice to you by email to the address on your Account, by posting on the Service, or in-app banner. You give notice to us at hello@stivio.ai.
• Entire agreement. These Terms, together with the Privacy Policy and Refund Policy, are the entire agreement between you and us regarding the Service and supersede prior agreements.
• Headings. Headings are for convenience only and do not affect interpretation.
• Independent contractors. Nothing in these Terms creates a partnership, joint venture, agency, or employment relationship.
