Terms of Service

1. Acceptance of terms

These Terms of Service (the “Terms”) govern your access to and use of CaptionLayer (the “Service”), operated by TATLAB LTD, a company registered in England and Wales (Company No. 17289453), with its registered office at 128 City Road, London, EC1V 2NX, United Kingdom (“we”, “us”, or “our”). By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

2. Description of the Service

CaptionLayer lets you upload short-form video, automatically transcribe its audio, and export videos with burned-in captions along with subtitle files (such as SRT, VTT, and ASS). Uploads must meet the format, file size, and duration limits shown in the app and must contain an audio track. The Service is offered on a pay-as-you-go basis: you purchase a balance of processing minutes and spend them as you caption videos. It also offers an API and API keys for programmatic access. Calendar planning and publication drafts are free. Publish and Studio combine monthly processing minutes with automatic publishing to TikTok, Instagram and YouTube.

3. Accounts

You may create an account with an email address and password, or by signing in with a third-party identity provider such as Google. You are responsible for keeping your credentials confidential and for all activity under your account. You must provide accurate information and be at least 16 years old (or the age of digital consent in your country). API keys are shown once at creation and cannot be recovered if lost.

4. Acceptable use

You agree not to use the Service to:

• upload, process, or distribute content that is unlawful, infringing, or that you do not have the rights to;
• violate the intellectual property, privacy, or publicity rights of others;
• circumvent usage limits, resell the Service without authorisation, or share access to defeat billing;
• reverse engineer, disrupt, or place undue load on our infrastructure; or
• process content depicting or targeting minors unlawfully, or any other prohibited material.

We may suspend or remove content and accounts that breach this section.

5. Payment, billing & refunds

Paid minutes are sold as prepaid packs and processed by our payment provider, Stripe. New accounts receive a small number of free minutes to try the Service, shown at signup. Minutes are charged based on the actual length of each clip you caption. Editing a clip and re-rendering it reuses the existing transcription; your first two re-renders of the same clip do not consume additional minutes. Purchased credits remain valid for 12 months from the date of purchase. Prices are shown at checkout and may be exclusive of taxes, which are added where applicable.

You may optionally save a payment method for faster top-ups. If you do, we will only charge it for a purchase you confirm; we do not charge saved cards automatically without your action. You can remove a saved card at any time. This statement applies to one-time top-ups. A monthly plan that you explicitly start renews automatically and charges your payment method each month until you cancel renewal.

Consumers may have statutory cancellation and refund rights, including a 14-day withdrawal period where applicable. If you expressly request immediate provision of a service and then withdraw, a proportionate charge for the service supplied may apply as permitted by law. Starting to use the Service does not by itself waive your statutory rights. Contact us to request a refund or withdrawal; unused processing minutes may be refunded on request. Nothing in these Terms limits mandatory consumer remedies.

Mini costs USD $5 once for 20 processing minutes; Creator costs USD $15 once for 100 minutes. Publish costs USD $39 per month and includes 100 processing minutes per paid month and up to 3 connected social accounts. Studio costs USD $79 per month and includes 250 processing minutes per paid month and up to 6 connected social accounts. Captions, auto edit and export formats are available on all plans. Each TikTok account, Instagram account or YouTube channel counts separately, including when you make no posts. Monthly minutes are credited after the initial paid invoice and each paid monthly renewal. Unused minutes carry over in your balance and remain valid for 12 months from crediting, including after cancellation. No existing balance is reset. Additional processing minutes can be purchased with Mini or Creator. Plan changes are handled through Support with your agreement to the price and effective date before any charge. Your recurring total and applicable taxes are shown before payment. Existing purchases are not automatically converted to subscriptions. New subscriptions do not include separately purchased extra social-account slots.

You can cancel renewal in Publishing at any time. Cancellation takes effect at the end of your paid period; ordinary cancellation does not automatically refund the current period, subject to statutory rights and any refund we agree with you. Removing a saved payment method or disconnecting a social account does not cancel subscription renewal or change your plan. If renewal is unpaid or your paid period expires, automatic publishing is unavailable and social connections are disconnected during account cleanup. Reconnection may be required after renewal. Drafts and prepaid processing minutes remain available independently.

To exercise an applicable statutory right to withdraw, email support@captionlayer.org with a clear statement that you wish to withdraw, your account email, the purchase or subscription date, and your name. You may use: “I give notice that I withdraw from my contract for [service], ordered on [date]. My name is [name], account email [email], address [address], and today’s date is [date].” You do not have to use this wording.

6. Your content

You retain all rights to the videos, audio, and other materials you upload (“Your Content”). You grant us a limited, non-exclusive licence to store, process, and transmit Your Content solely to provide the Service — including sending audio to our transcription provider and generating captioned outputs, and, when you authorize automatic publishing, transferring your chosen rendered videos and post metadata to Zernio and the selected social platforms. You are responsible for ensuring you have the rights and any necessary consents to upload and process Your Content.

7. Service availability

Transcription is performed by third-party providers and results are supplied “as is” without any guarantee of accuracy. We aim for high availability but do not guarantee that the Service will be uninterrupted or error-free, and we may modify, suspend, or discontinue features.

Connecting an account authorizes access for the publishing features you request. You must control the account and review the video, text, audience, commercial-content and synthetic-content disclosures before scheduling. Platform terms, account eligibility and posting limits also apply. We do not promise exact publication times, acceptance by a platform, views, reach or engagement. Processing, outages, moderation and expired permissions can delay or prevent delivery.

Schedule automatic delivery only within your current paid period; later dates can be saved as drafts. Cancellation of a scheduled post remains pending until the publishing service confirms it. Content already processing or published may require action on the social platform. Cancelling your subscription, disconnecting an account or deleting a draft does not remove already published posts. If delivery status is uncertain, check the platform or contact Support before creating a replacement to avoid duplicate posts.

8. Intellectual property

The Service, including its software, design, and branding, is owned by us or our licensors and is protected by law. Except for the rights expressly granted to you, no rights are transferred. You may not use our trademarks without permission.

9. Disclaimer of warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT, TO THE FULLEST EXTENT PERMITTED BY LAW.

10. Limitation of liability

To the fullest extent permitted by law, we are not liable for any indirect, incidental, special, or consequential damages, or loss of profits, data, or goodwill. Our total liability arising out of or relating to the Service is limited to the amount you paid us in the 12 months before the event giving rise to the claim. Nothing in these Terms excludes liability that cannot be excluded by law, such as for fraud or death or personal injury caused by negligence.

11. Termination

You may stop using the Service and close your account at any time. We may suspend or terminate your access if you breach these Terms or if required to protect the Service or comply with law. Sections that by their nature should survive termination will continue to apply.

12. Changes to these Terms

We may update these Terms from time to time. For material changes we will provide reasonable notice by email or through the Service. Your continued use after changes take effect constitutes acceptance.

13. Governing law

These Terms are governed by the laws of England and Wales. The courts of England and Wales have jurisdiction, except that if you are a consumer you may also bring proceedings in the courts of your country of residence where required by local law.
