Echoly — Privacy Policy

Last updated: 2026-06-11

TL;DR. Audio is processed only while you are actively translating, solely to produce your dub, and no recordings are stored. We keep the minimum account data needed to run the service (email, plan, credit usage) and we never sell personal data or show ads.

What Echoly is

Echoly is a Chrome extension and companion website (echolyhq.com) that dubs the video you are watching into your chosen language with an AI voice, on sites such as YouTube, Coursera, and Udemy. The extension talks exclusively to Echoly's own service at api.echolyhq.com.

Data we process

Account data. When you sign in at echolyhq.com we store your email address, plan tier, and sign-in session. The extension reads your session on echolyhq.com only to authenticate your requests — it never sees your password (sign-in is by emailed code/link).
Video audio and captions. When you press Start, the audio of the video on the active tab (captured with the standard HTMLMediaElement.captureStream() API), or the video's public caption track where available, is streamed to api.echolyhq.com to be transcribed, translated, and synthesized into your dub. Processing is transient and in-memory; no recordings are stored. Nothing is captured while a session is not running.
Usage metering. We record how many credits each session consumes (duration, tier, language pair) so we can enforce plan limits and show your remaining balance. We do not keep a log of which videos you watch tied to their content.
Payment data. Subscriptions are processed by Stripe. Card details go directly to Stripe and never touch Echoly's servers; we store only your subscription status. See Stripe's privacy policy.
Settings. Language, voice, volume, subtitle style, and per-site preferences are stored in chrome.storage and synced to your account so they follow you across devices.

What we do NOT do

No storing or reselling of audio, transcripts, or translations after your session.
No reading of your browsing history; the extension activates only on supported video sites.
No advertising, ad targeting, or sale of personal data to third parties.
No collection of data unrelated to providing and improving the dubbing service.

Subprocessors

Echoly uses vetted cloud infrastructure and AI model subprocessors to perform transcription, translation, and speech synthesis on our behalf. Audio sent to subprocessors is used solely to produce your translation in the moment and is not used to train models or retained as recordings.

Data retention

Session audio: not retained. Usage records and account data: kept while your account is active. Delete your account (or email us) and we remove your personal data within 30 days, except records we must keep for tax or accounting law.

Extension permissions

activeTab, scripting, tabs — to detect the video page you invoked Echoly on and show the in-page control panel.
storage — to keep your preferences and session state on your device.
webRequest — to detect the video's caption track on supported sites so captions can be translated.
cookies — to read your echolyhq.com sign-in session so the extension can act as your account.
Host permissions for youtube.com, coursera.org, udemy.com, echolyhq.com, and api.echolyhq.com — the supported video sites plus Echoly's own service.

Your rights and choices

Stop a session at any time; capture ends immediately when you stop or close the tab.
Sign out or uninstall the extension to remove all locally stored data.
Request a copy or deletion of your account data at any time via the contact below.

Children

Echoly is not directed at children under 13 and does not knowingly collect personal information from them.

Changes to this policy

If we materially change how Echoly handles data we will update this page and bump the date at the top. Continued use after a change constitutes acceptance.
