Privacy policy

Your videos never reach us.

This page explains, in plain English, what OpaCaptions collects on this website and in the app. Last updated: 29 October 2026.

The short version

• Your videos, audio, transcripts and file names never leave your computer. Captioning happens entirely on your own PC.
• If you join the waitlist, we keep your email address and two answers you choose (what you make, which plan interests you) so we can tell you when OpaCaptions launches.
• We don't sell or share your data, and this website uses no advertising or analytics trackers.

The OpaCaptions app

Speech recognition (OpenAI's open-source Whisper model) and video rendering run locally on your computer. Your footage is never uploaded to us or to any AI service, and it is never used to train AI.

The app uses the internet for two things only:

• Downloading the speech model the first time you use it. The model files come from Hugging Face, a model-hosting service; like any download, that request reveals your IP address to them.
• Activating your licence. This sends your licence key and an anonymous device ID, so we can check the licence and enforce the number of PCs on your plan.

This website

Waitlist. When you join early access we store your email address, what you make (for example "podcasts"), the plan you're interested in and the time you joined. To stop spam we also store a one-way, salted hash of your IP address, not the address itself. We use this only to email you about the OpaCaptions launch and your early-bird price.

Cookies. The public website sets no cookies.

No third parties. Fonts, videos and images are served from our own server. The site has no ads, analytics, social-media trackers or embedded third-party scripts.

Hosting. The website and waitlist are hosted by our web host, Namecheap, which processes data on our behalf to run the servers.

How long we keep it

We keep your waitlist details until you unsubscribe or ask us to delete them, and no longer than needed once OpaCaptions has launched.

Your rights

You can ask to see, correct or delete your data, or withdraw your consent, at any time. This applies wherever you live, including under the EU/UK GDPR and India's Digital Personal Data Protection Act. Email support@opacaptions.com and we'll respond promptly.

Changes

If we change this policy we'll update this page and the date above. If a change affects how we use your email, we'll tell you first.
