These Terms of Service govern your access to and use of Caika, including its website, accounts, AI image-generation features, public gallery, subscriptions, and credit packs. By creating an account, purchasing credits, or using the service, you agree to these Terms.
You must be at least 18 years old and legally able to enter into a binding agreement to use Caika. If you use Caika for an organization, you represent that you have authority to bind that organization, and "you" includes both you and the organization.
You may use the service only in compliance with these Terms and all laws that apply to you. If you do not agree to these Terms, do not use Caika.
You must provide accurate account information and keep it current. You are responsible for activity under your account and for safeguarding your password, sign-in links, connected OAuth account, and active sessions. You may not sell, share, or transfer an account without our written permission.
Notify us promptly at support@caika.app if you believe your account or payment method has been accessed without authorization. We may require reasonable verification before changing account access, billing, or ownership information.
Caika uses third-party artificial intelligence and infrastructure providers to process prompts, reference images, and generation settings. A request may be retried or routed to another configured provider when a provider is unavailable. Processing times, supported features, and output quality may vary by model and provider.
AI outputs are probabilistic. They may be inaccurate, incomplete, offensive, unexpected, or unsuitable for your intended purpose. Caika does not promise that an output will match your prompt, be unique, be error-free, or be available by a particular time. You must review each output before relying on, publishing, or commercially using it.
"Your Content" includes prompts, reference images, profile information, generation settings, and other material you submit to Caika. As between you and Caika, you retain any rights you already hold in Your Content. You represent that you have all permissions needed to submit and process it and that doing so does not violate law or another person's rights.
You grant Caika a worldwide, non-exclusive, royalty-free license to host, copy, transmit, process, adapt for technical purposes, and otherwise use Your Content only as needed to operate, secure, moderate, support, and provide the service. This license includes allowing our service providers to process Your Content for those purposes and lasts for as long as reasonably necessary to provide the service and meet legal, security, backup, and dispute-resolution obligations.
If you choose to publish a generation in the public gallery, you also authorize Caika to publicly display, distribute, and make that generation available together with associated information such as its prompt, model, settings, profile name, and avatar. Removing an item from the gallery ends future use under this public-display permission after a reasonable processing period, but does not undo copies previously shared by others or records we must retain. Public works may remain in de-identified form after account deletion where permitted by law.
Subject to these Terms, you may use generated outputs for lawful personal or commercial purposes to the extent permitted by applicable law and any terms imposed by the underlying model provider. Caika does not claim ownership of rights that applicable law grants to you in an output.
Because different users may submit similar prompts and AI systems may produce similar or identical material, outputs are not guaranteed to be exclusive. Caika does not guarantee that an output is eligible for copyright, trademark, patent, or other intellectual-property protection, or that using it will not infringe another person's rights. You are responsible for clearance, attribution, consent, and other review required for your use.
You may not use Caika, Your Content, or generated outputs to break the law, harm others, interfere with the service, or evade safeguards. Prohibited conduct includes:
We may use automated systems and human review to detect abuse, moderate prompts or images, investigate reports, and enforce these Terms. Moderation may be performed by configured third-party providers. Moderation is not perfect, and the absence of a warning or block does not mean content is lawful, accurate, or permitted.
We may reject a request, remove public content, restrict features, preserve relevant records, or report conduct to authorities when reasonably necessary to protect users, the service, or legal rights. You may contact us if you believe an enforcement action was made in error.
Credits are limited, revocable units used to access generation features. They are not money, stored value, a bank balance, or property; have no cash value; are non-transferable; and may not be sold or exchanged. Credit costs may vary by model or feature and will be shown in the service before or when a request is submitted.
Subscription credits are allocated monthly, including during an annual subscription, and generally expire at the next monthly allocation without rollover. Credits purchased in one-time packs and signup, contribution, or other promotional credits currently do not expire unless offer-specific terms state otherwise. We may change credit rates or rules prospectively, but will not retroactively reduce credits already validly acquired except to correct an error, reverse a refund or disputed payment, address abuse, or comply with law.
A generation request may place a temporary hold on credits. Credits are deducted when the request reaches the billable state defined by the service. Displayed balances may take a short time to reflect pending jobs, reversals, or restored credits.
Payments are processed through Creem. Prices are charged in U.S. dollars unless the checkout expressly states otherwise, and taxes or payment-provider charges may apply. Caika does not store your full payment-card details.
Paid subscriptions renew automatically for the selected monthly or annual billing period until canceled. An annual plan is charged for the year at the start of each annual period even though its credits are released monthly. By purchasing a subscription, you authorize recurring charges to your selected payment method.
We may change prices for future purchases or renewal periods. Where required, we will provide advance notice and an opportunity to cancel before a changed subscription price takes effect. Failed payment may cause a subscription, credits, or service access to be limited or suspended.
Upgrades and changes from monthly to annual billing may take effect immediately and may include a prorated charge or credit shown during the billing flow. Downgrades and changes from annual to monthly billing generally take effect at the end of the current paid period.
You may cancel renewal using the billing controls made available to your account or by contacting support@caika.app. Cancellation stops future renewal and normally takes effect at the end of the current paid period; it does not by itself create a refund. Deleting or losing access to your Caika account does not automatically cancel a subscription processed by Creem, so cancel the subscription before requesting account deletion.
Except where applicable law requires otherwise, purchases are final and non-refundable because subscriptions and credits provide immediate access to digital services. We do not ordinarily provide partial or prorated refunds for unused time, unused credits, plan changes, cancellation, dissatisfaction with an AI output, or failure to cancel before renewal.
We may review exceptional requests involving a duplicate charge, verified non-delivery of a purchased entitlement, an unauthorized payment, or another circumstance required by law. Approved monetary refunds are processed through Creem and may result in reversal of related credits, benefits, or subscription access.
When a generation fails in a state recognized by Caika as non-billable, the system may release or restore the associated held credits if those credits are still valid and have not been reversed. Credit restoration is not a cash refund and does not extend the original expiration date. See the Refund Policy for further details.
Caika and its licensors retain all rights in the service, including its software, interface, branding, documentation, databases, and non-user content. These Terms give you a limited, non-exclusive, non-transferable, revocable right to access the service for its intended purpose; they do not transfer ownership of Caika technology or branding.
Feedback you voluntarily provide may be used without restriction or payment, provided we do not identify you publicly as its source without permission.
Caika depends on third-party services for AI generation, moderation, authentication, hosting, storage, email, queues, and payment processing. Their services may be subject to separate terms and privacy practices, and their availability or decisions may affect Caika. We are not responsible for a third party's independent products, websites, or conduct.
Links or integrations do not imply endorsement. You are responsible for complying with third-party terms that apply to services or content you choose to use with Caika.
We aim to keep Caika available but do not guarantee uninterrupted, secure, or error-free operation. Maintenance, capacity limits, provider outages, model changes, network failures, or events outside our control may delay or prevent access or generation.
We may add, change, limit, or discontinue features, models, credit costs, or integrations. Where a change materially reduces a paid service, we will use reasonable efforts to give notice or provide a reasonable transition, subject to security, legal, and third-party constraints.
You may stop using Caika at any time. We may suspend or terminate access, remove content, or restrict credits when we reasonably believe you violated these Terms, created legal or security risk, engaged in fraud or payment abuse, or could harm Caika, its providers, or other users. Where appropriate, we will provide notice and an opportunity to appeal or cure.
On termination, your right to use the service ends. Provisions that by their nature should survive will remain effective, including payment obligations, licenses needed for retained records, intellectual-property provisions, disclaimers, liability limits, indemnity, and dispute terms. Account termination does not automatically cancel an external subscription or erase third-party and backup copies.
To the maximum extent permitted by law, Caika is provided "as is" and "as available." We disclaim implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy, and uninterrupted or secure availability. We do not warrant any AI output, model, public-gallery content, or third-party service.
You use and publish outputs at your own risk. Caika is not legal, medical, financial, or other professional advice, and no output should be treated as verified factual information without independent review.
To the maximum extent permitted by law, Caika and its service providers will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, revenue, data, goodwill, business opportunity, or the cost of substitute services, arising from or related to the service, even if advised that such loss was possible.
To the maximum extent permitted by law, Caika's total liability for all claims arising from or related to the service will not exceed the greater of the amount you paid to Caika during the 12 months before the event giving rise to the claim or USD 100. These exclusions and limits do not apply where prohibited by law, including liability that cannot legally be excluded or limited.
To the extent permitted by law, you will defend, indemnify, and hold harmless Caika and its service providers from third-party claims, losses, liabilities, and reasonable costs arising from Your Content, your use or distribution of outputs, your violation of these Terms or law, or your infringement of another person's rights. This obligation does not apply to the extent a claim was caused by Caika's own unlawful conduct, and it does not limit non-waivable consumer rights.
We may update these Terms to reflect service, legal, security, or business changes. We will post the revised Terms with a new effective date and, when a change is material, provide additional notice where reasonably practicable. Changes do not retroactively alter completed purchases unless required by law. Your continued use after revised Terms take effect means you accept them; if you do not agree, you must stop using the service and cancel renewal.
These Terms do not waive rights or remedies that cannot be waived under the laws applicable to you. Any dispute will be handled by a court or other forum with jurisdiction under applicable law; these Terms do not designate a different governing jurisdiction or exclusive venue. Mandatory consumer-protection rules remain unaffected.
Before filing a formal claim, please contact us at support@caika.app with a description of the issue so the parties can try to resolve it informally. Questions about these Terms may be sent to the same address.
