1. Acceptance of Terms

By creating an account, accessing, or using AVCaption (the "Service"), you agree to be bound by these Terms of Service ("Terms"). If you are using the Service on behalf of an organization, you represent that you have authority to bind that organization to these Terms. If you do not agree, you must not use the Service.

These Terms constitute a legally binding agreement between you ("User", "you") and AVCaption ("we", "us", "our"). By clicking "Get Started", "Sign Up", or similar, or by accessing any part of the Service, you acknowledge that you have read, understood, and agree to these Terms and our Privacy Policy.

2. Description of Service

AVCaption is an encrypted video hosting and streaming platform. The Service provides:

  • Video hosting — upload video files in formats including MP4, MKV, AVI, MOV, WebM, FLV, WMV, TS, M4V, MPG, MPEG, 3GP, OGV, M2TS, and MTS
  • Adaptive encoding — GPU-accelerated HLS encoding with multiple quality variants (360p, 480p, 720p, 1080p, 1440p, 2160p)
  • Encryption — every video segment is encrypted with multi-key batches for maximum security
  • Global CDN delivery — video segments stored on Cloudflare R2 with 300+ edge locations worldwide
  • Embeddable player — a customizable video player that works on any website, LMS, or application
  • AI Studio — OCR-based subtitle extraction and AI-powered translation (Enterprise plan)
  • Analytics — real-time view tracking and engagement metrics
  • REST API — programmatic video management (Enterprise plan)

3. Account Registration & Security

Eligibility

You must be at least 18 years of age to create an account and use the Service. By registering, you represent that you meet this requirement.

Account Information

You must provide accurate and complete information during registration (email address and password). You agree to keep your account information up to date.

Account Security

You are responsible for safeguarding your password and API keys. Passwords must be at least 8 characters. API keys are prefixed with avc_ and should be treated as secrets — do not expose them in client-side code or public repositories. You must notify us immediately if you suspect unauthorized access to your account.

One Person, One Account

Each individual may maintain only one account. Creating multiple accounts to circumvent restrictions, abuse free tier resources, or evade bans is prohibited.

4. Subscription Plans & Billing

AVCaption offers three subscription tiers:

Plan Price Key Features
Free $0/month Unlimited storage, up to 2K (1440p) quality, end-to-end encryption, embed player, basic analytics, custom player branding, domain whitelisting. Ad-supported playback.
Premium $100/month per 5TB Everything in Free, plus: zero ads, 4K Ultra HD quality, priority CDN on all videos, advanced analytics, email support (24h response).
Enterprise $250/month per 5TB Everything in Premium, plus: AI Studio (OCR + translation), dedicated encoding workers, custom watermarks (text + image), REST API access, VIP support (4h response).

Billing & Payment

Premium and Enterprise plans are billed monthly. Storage is metered in 5TB tiers — if your total storage exceeds 5TB, your plan automatically scales to the next tier (e.g., 5–10TB = 2x the monthly price). You will be notified before any tier change takes effect.

Free Plan

The Free plan is not a trial — it is a fully functional tier with unlimited storage and no expiration date. No credit card is required. Free plan videos include ad-supported playback.

Downgrade & Cancellation

You may downgrade or cancel your paid plan at any time from your dashboard. Downgrading preserves all existing videos and their embed links. Refunds are not provided for partial billing periods.

5. Acceptable Use Policy

You agree not to use the Service to:

  • Upload, host, or distribute content that infringes copyrights, trademarks, or other intellectual property rights of third parties
  • Upload illegal content, including but not limited to: child sexual abuse material (CSAM), content that promotes terrorism, or content illegal under applicable law
  • Upload content that is harmful, abusive, threatening, defamatory, obscene, or otherwise objectionable
  • Use the platform for mass-uploading videos with no legitimate viewership (spam/storage abuse)
  • Attempt to circumvent encryption, access controls, domain restrictions, or other security measures
  • Access, tamper with, or use non-public areas of the Service, our systems, or third-party systems
  • Reverse-engineer, decompile, disassemble, or attempt to derive the source code of the Service
  • Use automated tools, bots, or scrapers to access the Service, download content, or inflate view counts
  • Resell, redistribute, or sublicense the Service without written permission
  • Interfere with or disrupt the integrity or performance of the Service or its infrastructure

We reserve the right to remove content and suspend or permanently ban accounts that violate this policy, with or without notice.

6. Content Ownership & Licenses

Your Content

You retain full ownership of all video content, subtitles, metadata, and other materials you upload to AVCaption ("Your Content"). We claim no intellectual property rights over Your Content.

License to AVCaption

By uploading Your Content, you grant us a non-exclusive, worldwide, royalty-free license to:

  • Receive, store, and back up Your Content on our servers and CDN infrastructure
  • Encode, transcode, and process Your Content into HLS adaptive bitrate format
  • Encrypt Your Content using industry-standard encryption
  • Distribute Your Content via our CDN to end users as directed by your embed and sharing settings
  • Generate thumbnails, preview images, and metadata from Your Content
  • Process subtitle text through OCR and translation services when you explicitly initiate such processing

This license exists solely to enable us to operate and provide the Service. It terminates when you delete Your Content or your account.

Representations

By uploading, you represent and warrant that you own or have the necessary rights and permissions to upload, distribute, and display Your Content, and that Your Content does not violate any third-party rights or applicable law.

7. Video Processing & Encoding

When you upload a video, the following automated processing occurs:

  • Integrity verification — SHA-256 hash check to confirm the file was uploaded correctly
  • Media analysis — FFprobe extracts duration, resolution, codec, bitrate, and frame rate
  • Encoding — GPU-accelerated (NVIDIA NVENC) transcoding to H.264 HLS format with your selected quality variants
  • Encryption — each HLS segment is encrypted using multi-key batches
  • CDN upload — encrypted segments are uploaded to Cloudflare R2 for global distribution

Processing times depend on video length, resolution, and server load. Enterprise users receive dedicated encoding workers with priority queue access. You may select which quality variants (360p through 4K) to encode for each video.

8. Encryption & Security

All videos hosted on AVCaption are encrypted at rest and in transit:

  • Encryption: industry-standard encryption algorithm
  • Multi-key batches: each batch of segments uses a unique encryption key, limiting exposure if any single key is compromised
  • Transport security: all connections use TLS 1.2 or higher; HTTP is redirected to HTTPS
  • Client-side decryption: segments are decrypted in the viewer's browser using the Web Crypto API

While we employ industry-standard encryption, no security system provides absolute protection. We cannot guarantee that content will not be captured through screen recording, browser developer tools, or other client-side methods. Encryption protects against unauthorized downloading and redistribution of raw video files, but is not DRM.

9. Embedding & Distribution

Each video receives a unique embed token. You may embed videos on any website using the provided iframe code. Additional embedding features include:

  • Domain whitelisting: restrict playback to specific domains (supports wildcard subdomains)
  • Custom player branding: accent colors, subtitle style presets (up to 10), default language
  • Watermarks: text or image watermarks with configurable position, opacity, and size (Enterprise plan)
  • Anti-hotlink protection: embed player validates request origin headers

You are responsible for ensuring that your embed usage complies with the website where videos are embedded and with applicable laws.

10. AI Studio (OCR & Translation)

Enterprise plan users may access AI Studio, which provides:

  • OCR subtitle extraction: video frames are analyzed to extract hardcoded subtitle text using optical character recognition
  • AI translation: extracted or uploaded subtitles are translated between languages using third-party AI models (Claude by Anthropic, Gemini by Google)

AI Processing Terms

  • OCR processing extracts text from video frames — frames are processed temporarily and discarded after extraction
  • Translation sends subtitle text (not video content) to third-party AI providers for processing
  • You must provide your own API keys for AI translation services; AVCaption does not share your API keys
  • You may review and edit all AI-generated results before publishing
  • AI-generated translations may contain errors — you are responsible for reviewing accuracy before publishing
  • AI providers' own terms of service and privacy policies apply to text processed through their APIs

11. REST API Usage

Enterprise plan users receive REST API access for programmatic video management. API usage is subject to:

  • Authentication: Bearer token (JWT) or API key (avc_ prefix) via header or query parameter
  • Rate limits: applied to sensitive endpoints (upload, delete, key regeneration) to prevent abuse
  • Fair use: API access is for legitimate automation of video management tasks; bulk scraping or automated attacks are prohibited

We may revoke API access for accounts that abuse API endpoints or violate these Terms.

12. Storage, CDN & Availability

Storage

Free plan users receive unlimited storage with no tier system. Premium and Enterprise storage is billed in 5TB tiers. Encoded video files (HLS segments, thumbnails) count toward your storage usage in addition to source files.

Content Delivery

Video segments are distributed via Cloudflare R2's global CDN (300+ edge locations). Segments are cached as immutable objects for optimal performance. Free plan videos earn priority CDN placement through strong view performance; Premium and Enterprise videos receive priority CDN on all content.

Availability

We target 99.9% uptime for the Service, but do not guarantee uninterrupted availability. Scheduled maintenance, infrastructure updates, CDN outages, and force majeure events may cause temporary unavailability. We will make reasonable efforts to notify users of planned downtime in advance.

Data Persistence

We do not delete videos due to inactivity — even on the Free plan, your content remains online indefinitely as long as your account is in good standing.

13. Termination & Suspension

Termination by You

You may delete your account at any time from your dashboard settings. Upon account deletion, all your videos, subtitles, settings, and associated data will be permanently deleted within 30 days. Embed links will stop working immediately upon deletion.

Termination by Us

We may suspend or terminate your account if you:

  • Violate these Terms or our Acceptable Use Policy
  • Engage in fraudulent or illegal activity
  • Abuse the platform (spam uploads, storage abuse, view inflation)
  • Fail to pay applicable fees for 30+ days

For violations, we may terminate accounts permanently and remove all associated content without refund. We will make reasonable efforts to notify you before or at the time of termination, except in cases of severe abuse.

14. Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY. WE DISCLAIM ALL WARRANTIES INCLUDING, WITHOUT LIMITATION, WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

Without limiting the foregoing, we do not warrant that:

  • The Service will be uninterrupted, secure, or error-free
  • Encryption will prevent all unauthorized access to your content
  • AI-generated subtitles or translations will be accurate or complete
  • Video encoding quality will meet your specific requirements

15. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, AVCAPTION SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, DATA, BUSINESS OPPORTUNITIES, OR GOODWILL, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE.

OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING UNDER THESE TERMS SHALL NOT EXCEED THE AMOUNT YOU PAID TO US IN THE 12 MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR $100, WHICHEVER IS GREATER.

16. Indemnification

You agree to indemnify, defend, and hold harmless AVCaption, its officers, directors, employees, and agents from any claims, damages, losses, liabilities, and expenses (including reasonable legal fees) arising out of:

  • Your use of the Service
  • Your Content or its distribution
  • Your violation of these Terms
  • Your violation of any third-party rights, including intellectual property rights

17. Changes to These Terms

We may revise these Terms at any time by posting an updated version on this page. Material changes will be communicated via email or dashboard notification at least 14 days before they take effect. Your continued use of the Service after the effective date constitutes acceptance of the revised Terms. If you disagree with any changes, you must stop using the Service and delete your account.

18. Governing Law

These Terms shall be governed by and construed in accordance with applicable law. Any disputes arising under these Terms shall be resolved through good-faith negotiation. If negotiation fails, disputes shall be submitted to binding arbitration. You waive any right to participate in class-action lawsuits or class-wide arbitration.
