1. Who We Are

Capti is operated by Lab 37 ("we", "us", "our"). We provide AI-assisted tools to generate multilingual captions for Final Cut Pro.

2. What We Collect

  • Account data: Provided via Clerk (e.g., email, name, and identifiers managed by Clerk).
  • Billing data: Processed by Polar (Merchant of Record). Polar handles payments, invoicing, and tax collection on our behalf. We do not store full payment card details.
  • Job data: For each captioning job, we store job metadata, audio files, transcription files (list of words with timestamps), grouping files (list of words within groups), SRT files, and FCPXML files.
  • User data: Presets, subscription information, and credit amounts.
  • Usage and attribution data: We use Vercel Analytics, PostHog, and Google Ads (Google tag). PostHog, Vercel Analytics, and Google Ads tracking run only after explicit consent. Vercel Speed Insights remains anonymous.

3. How We Use Data

  • Provide, operate, and improve Capti.
  • Process audio transcription using AssemblyAI and caption grouping using Groq.
  • Manage authentication via Clerk and billing via Polar.
  • Communicate account notifications via Clerk, billing notifications via Polar, and marketing emails via Loops.so (with your consent).
  • Maintain security and prevent abuse.
  • Measure usage and ad attribution with Vercel Analytics, PostHog, and Google Ads after explicit consent.

4. Data Sharing

We share data with the following third-party providers to deliver our service. See our Data Processing & Providers documentation for complete details and links to each provider's privacy policy:

5. Data Retention

User data and job files are stored on Convex and will be automatically deleted after 2 years of account inactivity. You can manually delete individual jobs from the job page or delete your entire account from the user menu at any time.
