Subprocessors

Current launch list

• Stripe - payment processing, checkout, billing portal, invoices, subscription status, and payment-related webhooks.
• Cloudflare - R2 object storage in prod-like environments, Turnstile CAPTCHA when signup protection is enabled, and Cloudflare Tunnel/DNS-style infrastructure where deployed.
• Hetzner - hosting for the application control plane where deployed.
• RunPod - on-demand compute for media processing (video ingest and export rendering jobs).

Infrastructure that may change

• CutCaption may add or replace hosting, database, queue, worker, GPU, or managed speech-to-text providers as the production architecture evolves.
• Sentry and similar diagnostics tools are optional and depend on production configuration.
• Provider-specific data locations, transfer mechanisms, retention terms, and DPA availability can vary by provider and plan.

Changes to subprocessors

CutCaption may add, replace, or remove subprocessors as the product and infrastructure evolve. Material production changes should be reflected here and in the Privacy Policy.

AI training scope

CutCaption providers may process project content only to deliver the requested transcription, translation, storage, preview, export, security, diagnostics, or support function. They are not permitted to use uploaded video, audio, subtitles, transcripts, captions, translations, or derived project data to train public or provider-owned general-purpose AI models.
