Privacy policy
Updated November 2026
Your video
When you create captions, your browser reads the video file on your device and extracts the audio track; the video file itself is not uploaded. When you choose Export → Video with captions, the video is uploaded so the captions can be burned in. The uploaded video is deleted as soon as the export finishes, and the exported MP4 is deleted after 7 days.
Your audio
The audio is sent in short pieces to SubtitlePop’s server, which passes each piece to a speech recognition model on Cloudflare Workers AI and returns the text. SubtitlePop does not store the audio or the recognised text on its servers. Cloudflare processes the audio to provide the recognition; see Cloudflare’s privacy policy for how it handles data.
Translation
When you translate captions, the text of the captions — not the audio or the video — is sent to an AI language model provider that returns the translation. SubtitlePop does not store the caption text or the translation on its servers. We will name our current provider on request; write to the address below.
Your captions
Captions and your edits are saved in your browser’s local storage on your device, so you can come back to them. Clearing your browser data removes them.
Your account
If you sign in with Google, we store your email address, name and profile picture from Google, your minutes balance and a record of minutes used. To keep free minutes to one account per person, we also keep a random identifier stored in your browser and a one-way hash of your network address block — not the address itself.
Payments
Payments are handled by our payment providers; we don’t see or store your card details.
Usage data
We use Google Analytics 4 and Plausible Analytics to see which pages are visited and which features are used — for example that a file was transcribed and how long it was. Google Analytics sets cookies and receives your IP address and device information; Plausible uses no cookies. In Europe, Google Analytics loads only after you accept it in the cookie notice; anywhere, you can change your choice with the “Cookie settings” link at the bottom of every page. Neither receives your audio, video or captions. We don’t sell personal data.
Your data rights
You can ask us at any time to:
- See your data — your account page shows your email address, plan and minutes; write to us for a copy of everything we hold about you.
- Correct your data — your name, email address and picture come from your Google account; tell us if anything else we hold is wrong and we will fix it.
- Delete your data and close your account — write to us from the email address on the account. We delete the account, its minutes balance and usage records, and any exported videos still stored. Payment records are kept by our payment provider for as long as tax and accounting law requires.
- Object to or limit how we use your data, or receive it in a portable format.
Send requests to support@subtitlepop.com. We reply within 30 days, and usually within a few days. Captions saved in your browser are under your control: clearing the site’s data in your browser removes them. You can turn Google Analytics off with the “Cookie settings” link at the bottom of every page, or block analytics with your browser settings or a content blocker. If you are in the EU or UK and think we have handled your data wrongly, you can also complain to your local data protection authority.
