Terms of Service

Last updated: 1 June 2026

Acceptance of these Terms

These Terms of Service ("Terms") are an agreement between you and Thumbo (thumbo.ai, "we," or "us") and govern your use of thumbo.ai and related services (the "Service"). By creating an account or using the Service, you agree to these Terms and to our Privacy Policy. If you do not agree, please do not use the Service.

Eligibility and your account

You must be at least 16 (or the age of majority where you live, if higher) and able to enter a binding contract. You are responsible for keeping your account credentials secure and for all activity under your account. Tell us right away at [email protected] if you suspect unauthorized use.

The Service

Thumbo is an AI tool that helps you create YouTube thumbnails. You upload images — including, if you choose, photos of yourself — select styles, and provide prompts, and the Service uses AI to generate new thumbnail images ("Outputs"). We may add, change, or remove features over time.

Subscriptions, billing and cancellation

Thumbo is offered on paid subscription plans (for example, Starter and Pro), each including a monthly allowance of thumbnail generations; current plans and prices are shown at checkout. We may offer a free trial — if you do not cancel before it ends, your paid subscription begins automatically and your payment method is charged. Payments are processed by Stripe, and by subscribing you authorize us (through Stripe) to charge the applicable fees. Subscriptions renew automatically each period at the then-current price until you cancel. You can cancel anytime in your settings or by emailing [email protected]; cancellation takes effect at the end of the current period, and fees already paid are non-refundable except where required by law or expressly stated. We may change prices or allowances with reasonable notice, effective at your next renewal. Unused allowance does not roll over, and prices may exclude applicable taxes.

Your content and the rights you grant us

You keep ownership of the images and prompts you upload ("User Content"). You grant us a worldwide, non-exclusive, royalty-free license to host, store, process, and transmit your User Content solely to operate and provide the Service — including sending it to our AI providers to generate your Outputs. This license ends when you delete the content or close your account, except for limited backups and as needed to comply with law. We will not use your User Content or Outputs to train or fine-tune AI models unless you separately opt in, as described in our Privacy Policy, and you can withdraw that consent at any time.

Your responsibilities and content rules

For every image you upload, you represent that you own it or have all necessary rights, and that uploading and processing it breaks no law or third-party right. You may upload photos of yourself; you may only upload photos of other identifiable people if you have their explicit consent. You may not upload images of celebrities or public figures, impersonate anyone, or create misleading deepfakes. You also may not upload or generate content that infringes others' rights; that is unlawful, defamatory, harassing, or hateful; that sexualizes minors or depicts non-consensual intimate imagery; that is fraudulent or deceptive; or that violates our AI providers' usage policies. We may remove content and suspend or terminate accounts that break these rules.

AI Outputs — ownership and limitations

As between you and us, and to the extent the law allows, we assign to you our rights in the Outputs you generate, provided you have complied with these Terms and paid any applicable fees — you are responsible for how you use them. Because AI models can produce similar results for different users, we do not guarantee Outputs are unique, original, or free of similarity to other works, and they may contain errors or artifacts, so review them before publishing. You are responsible for making sure your use of Outputs complies with the rules of any platform where you post them (for example, YouTube).

Our intellectual property and third-party services

The Service — including its software, design, the Thumbo name and logo, styles, and templates (but not your User Content) — belongs to us or our licensors. We grant you a limited, non-exclusive, non-transferable, revocable license to use the Service for its intended purpose; you may not copy, modify, distribute, sell, or reverse-engineer it except as allowed by these Terms. The Service relies on third parties such as Stripe (payments) and Google (AI generation), whose own terms may apply, and we are not responsible for their acts or omissions.

Disclaimers and limitation of liability

The Service and all Outputs are provided "as is" and "as available," without warranties of any kind, and we do not warrant that Outputs will be accurate, unique, or error-free, or that the Service will be uninterrupted or secure. To the maximum extent permitted by law, thumbo.ai and its operators will not be liable for any indirect, incidental, special, or consequential damages, or any loss of profits, data, or goodwill, and our total liability for any claim relating to the Service will not exceed the greater of the amount you paid us in the 12 months before the claim or USD $100. Some places do not allow these limits, so they may not fully apply to you.

Indemnification and termination

You agree to indemnify and hold harmless thumbo.ai and its operators from claims, damages, and expenses (including reasonable legal fees) arising from your User Content, your use of Outputs, or your breach of these Terms or any law or third-party right — including any claim that you uploaded a photo of a person without their consent. You can stop using the Service and delete your account at any time. We may suspend or terminate your access if you break these Terms, fail to pay, or to protect the Service, other users, or comply with law; provisions that should survive termination (such as ownership, disclaimers, liability limits, and indemnification) will survive.

Changes, disputes and contact

We may update these Terms from time to time; if changes are material we will give reasonable notice, and continued use after they take effect means you accept the updated Terms. If a dispute arises, please contact us first at [email protected] so we can try to resolve it informally. Nothing in these Terms takes away any mandatory consumer-protection rights you have under the law of your country of residence.

By using Thumbo, you confirm that you have read and agree to these Terms. Questions? Contact us at [email protected].
