Subdus turns a video page you point it at into English subtitles. This page explains what we collect along the way, where it's stored, and what happens to it afterward.
What we process
When you submit a page URL, Subdus downloads or captures the video from that page, transcribes the speech in its original language, translates the captions to English, and produces a subtitle file. We only process what you submit — the Chrome extension's background lookups check whether a caption already exists for the page you're viewing, nothing more.
What we store, and where
Job output — the caption file, the extracted media, and a small metadata file recording the source page URL, when the job ran, and which account created it — is stored as plain files on the server that runs Subdus, under a configured output directory. In hosted mode that's a single machine we operate; it isn't mirrored to a third-party cloud storage provider.
Account identity is handled entirely by Clerk: Clerk holds your email address and sign-in credentials, and we never see or store a password. Subdus only keeps the account identifier Clerk gives us, plus your email for display purposes.
A Postgres database records your account and how many minutes of video you've submitted, so we can enforce your plan's allowance.
If you use the Chrome extension, it holds an API token you generate yourself, sent with each request so the extension can look up captions for the page you're currently viewing.
What we don't do
We don't sell your data. We don't use your submitted videos or generated transcripts to train models. We don't share job data with anyone beyond the services needed to run the pipeline (the transcription and translation backends, and Clerk for sign-in).
How long we keep things
Extracted source media is deleted automatically once it's no longer needed for an active job. Generated captions and their metadata are kept afterward so completed jobs and the Chrome overlay keep working — until you delete them from your dashboard, or we remove them (for cleanup, abuse, or if an account is closed).
Payment data
Subdus doesn't take card payments online. Vietnamese customers pay by a VietQR image; international customers pay by direct bank transfer, matched manually by the operator. We never see or store card numbers, because we never receive them.
