Your subtitles

CaptionDelta compares subtitles in your browser tab. Subtitle text, file names and track labels are not sent to the CaptionDelta server. There is no account and nothing is uploaded.

Your work is not saved in this browser after you close the tab. When you switch language or open checkout, it is handed to the next page through this tab’s session storage. The next page clears the temporary copy and restores it if less than one hour has passed.

What this browser keeps

Saved presets (tolerance and reading-speed settings only, with the 30-Day Pass) stay in local storage until you delete them. Campaign tags from the link you followed are kept for up to 30 days. During checkout, a signed checkout record is kept so the pass can be recovered after payment. Once payment is verified, a cookie records when your pass ends.

Copying and exports

Copied text, .txt downloads and PDF and CSV reports are created in your browser, and only when you click the button.

Payments

Square and PayPal handle payments on their own sites. CaptionDelta does not receive your card details. When you start a checkout, the server creates an order with the provider.

Usage counts

The server can count free exports (copies and .txt downloads, not exports of the unchanged sample, and not exports made with an active pass), checkout starts and verified purchases. A count may include campaign tags from the link you followed (utm_source, utm_medium and utm_campaign, matched to a short fixed list) and the page language (English, Spanish or unknown). For a verified purchase, it is the language of the page where checkout started. Counts never include subtitle text, file names or labels. Order numbers are stored only as keyed hashes.

CaptionDelta loads no third-party scripts, fonts, ads or trackers. Like any website, the server receives standard request information, such as your IP address, in order to deliver pages.
