Terms of Service

Last updated: February 23, 2026

1. Introduction

Welcome to MasterTimeline. These Terms of Service ("Terms") govern your access to and use of the MasterTimeline platform, available at mastertimeline.com, operated by MasterTimeline ("we", "us", or "our"). By accessing or using our service, you agree to be bound by these Terms. If you do not agree to these Terms, you must not use our service.

MasterTimeline is an AI-powered composition system that transforms story concepts into visual timelines, including AI-generated story beats, panel images, and video content. These Terms apply to all users of the platform, whether on a free trial or a paid subscription.

2. Account Terms

To use MasterTimeline, you must create an account and comply with the following requirements:

You must be at least 13 years of age to create an account and use the service. If you are under 18, you represent that your parent or legal guardian has reviewed and agreed to these Terms on your behalf.
You are responsible for maintaining the security of your account credentials, including your password. You must not share your login credentials with any other person.
Each individual may maintain only one account. Creating multiple accounts to circumvent usage limits, credit allocations, or other restrictions is prohibited.
You must provide truthful, accurate, and complete information when creating your account. You agree to promptly update your account information if it changes.
You are solely responsible for all activity that occurs under your account, whether or not you authorized that activity. You must notify us immediately at support@mastertimeline.com if you become aware of any unauthorized use of your account.

3. Subscriptions & Payments

MasterTimeline offers three subscription tiers, each providing a monthly allocation of AI credits and access to platform features:

Starter — $14.99 per month
Creator — $29.99 per month
Pro — $49.99 per month

All payment processing is handled securely through Stripe. By subscribing, you agree to the following:

Subscriptions are billed on a monthly recurring basis. Your subscription will automatically renew at the end of each billing cycle unless you cancel before the renewal date.
You may cancel your subscription at any time through your account settings or the Stripe customer portal. Cancellation takes effect at the end of the current billing period.
No prorated refunds are provided for partial months. If you cancel mid-cycle, you retain access to your subscription benefits until the end of the current billing period.
We reserve the right to change subscription pricing with at least 30 days' notice. Price changes will take effect at your next billing cycle after the notice period.
Promotional discounts, including first-month offers, apply only to the initial billing period and do not affect subsequent renewal charges.

4. AI Credits & Usage

MasterTimeline operates on a credit-based system. Credits are consumed when you use AI-powered features within the platform.

Credits are allocated monthly based on your subscription tier. The specific credit allocation for each tier is displayed on our pricing page.
Unused credits do not roll over. Any credits remaining at the end of your billing cycle expire and are replaced by your new monthly allocation.
Credits are consumed for the following actions, each at varying costs:
- Story beat generation (text AI)
- Panel image generation (image AI)
- Panel image editing (image AI)
- Video generation (varying costs by quality tier: standard, pro, and premium models)
- AI chat messages (creative director and post-production editor)
The specific credit cost for each action is displayed in the interface before you confirm the generation. Credit costs may be adjusted as we introduce new models or features.
Credits are deducted upon successful completion of a generation request. If a generation fails due to a system error, credits are not deducted.

5. Acceptable Use

You agree to use MasterTimeline in a lawful and responsible manner. The following activities are strictly prohibited:

Generating, uploading, or distributing content that is illegal, obscene, defamatory, threatening, or that promotes violence, hatred, or discrimination against any individual or group.
Using the platform to harass, abuse, stalk, or intimidate other users or any third party.
Attempting to reverse engineer, decompile, disassemble, or otherwise extract the underlying AI models, algorithms, or proprietary technology used by the platform or its third-party providers.
Using automated tools, bots, scrapers, or other programmatic means to access the platform, extract data, or generate content outside the normal user interface, unless explicitly authorized through our API.
Reselling AI-generated content produced through MasterTimeline as stock assets, templates, or in any bulk commercial capacity where the generated content itself is the primary product being sold.
Circumventing or attempting to circumvent credit limits, rate limits, subscription restrictions, or any other usage controls implemented by the platform.
Impersonating any person or entity, or falsely representing your affiliation with any person or entity.

Violation of these acceptable use policies may result in immediate suspension or termination of your account, at our sole discretion.

6. Content Ownership

We believe creators should own their work. Our content ownership terms are designed to be clear and creator-friendly:

Your content: You retain full ownership of your story concepts, scripts, uploaded images, uploaded videos, and all other content you create or upload to the platform.
AI-generated content: Images, videos, text, and other content generated by AI through your use of the platform are licensed to you for both commercial and personal use. You may use AI-generated content in your creative projects, publications, films, and other works without restriction.
No ownership claim by us: We do not claim ownership of your creative output, whether user-created or AI-generated. Your projects and their contents belong to you.
Service license: By uploading content to MasterTimeline, you grant us a limited, non-exclusive license to store, process, display, and transmit your content solely for the purpose of providing and improving the service. This license terminates when you delete your content or your account.

7. AI-Generated Content Disclaimer

MasterTimeline uses artificial intelligence models provided by third-party services to generate text, images, and video content. You acknowledge and agree to the following:

AI-generated content may not be factually accurate, contextually appropriate, or consistent across multiple generation requests. AI models are probabilistic in nature and may produce unexpected, inconsistent, or erroneous results.
We do not guarantee visual consistency, style fidelity, or narrative coherence across multiple AI-generated panels, images, or video clips. Results may vary between generation requests even with identical inputs.
All AI-generated content should be reviewed by you before use in any production, commercial, or public-facing context. You are solely responsible for evaluating the suitability of AI-generated content for your intended use.
AI text generation is provided through OpenRouter, and AI image and video generation is provided through Fal.ai. These third-party services are subject to their own terms of service, acceptable use policies, and content policies, which may impose additional restrictions on the content that can be generated.
We reserve the right to change AI model providers, models, or generation parameters at any time to improve quality, reduce costs, or comply with legal requirements.

8. Service Availability

MasterTimeline is provided on an "as is" and "as available" basis. While we strive to maintain high uptime and reliable performance, we make no guarantees regarding uninterrupted or error-free service.

We target high availability but do not guarantee 100% uptime. The service may experience occasional downtime due to maintenance, updates, infrastructure issues, or circumstances beyond our control.
We may perform scheduled maintenance during off-peak hours. Where possible, we will provide advance notice of planned maintenance windows.
Features, functionality, and user interfaces may change over time as we develop and improve the platform. We reserve the right to modify, suspend, or discontinue any feature or aspect of the service at any time.
Third-party AI services (OpenRouter, Fal.ai) may experience their own outages or degraded performance, which may temporarily affect AI generation capabilities within MasterTimeline.

9. Limitation of Liability

To the maximum extent permitted by applicable law:

Our total aggregate liability to you for any and all claims arising out of or related to these Terms or your use of the service shall not exceed the total amount you have paid to us in the twelve (12) months immediately preceding the event giving rise to the claim.
In no event shall we be liable for any indirect, incidental, special, consequential, punitive, or exemplary damages, including but not limited to damages for loss of profits, goodwill, data, or other intangible losses, regardless of whether we have been advised of the possibility of such damages.
We shall not be liable for any loss or damage arising from: your failure to maintain the security of your account; any unauthorized access to your account; content generated by AI models; actions of third-party service providers; or circumstances beyond our reasonable control.
Some jurisdictions do not allow the exclusion or limitation of certain damages. In such jurisdictions, our liability shall be limited to the greatest extent permitted by applicable law.

10. Termination

Either party may terminate this agreement under the following conditions:

Termination by us: We may suspend or terminate your account immediately and without prior notice if you violate these Terms, engage in prohibited activities, or if we are required to do so by law. We may also terminate accounts that have been inactive for an extended period, with reasonable prior notice.
Termination by you: You may delete your account at any time through your account settings. If you have an active subscription, cancellation of your subscription does not automatically delete your account or data.
Effect of termination: Upon termination or account deletion, we will delete your account data, uploaded content, generated content, and project data within thirty (30) days. Some anonymized or aggregated data may be retained for analytical purposes.
Sections of these Terms that by their nature should survive termination shall survive, including but not limited to: Content Ownership, Limitation of Liability, and any accrued payment obligations.

11. Changes to Terms

We reserve the right to modify these Terms at any time. When we make changes:

We will update the "Last updated" date at the top of this page.
For material changes that significantly affect your rights or obligations, we will notify you via the email address associated with your account at least 30 days before the changes take effect.
Your continued use of the service after the effective date of any changes constitutes your acceptance of the revised Terms. If you do not agree to the updated Terms, you must stop using the service and may delete your account.
