Privacy Policy

This policy explains how the Echo app for iPhone and iPad ("Echo", "we", "us"), run by Echo Team, handles information. Echo is built to keep as much as possible on your device.

Summary

• You do not need to create an account to use Echo.
• Your practice history, saved words and settings are stored on your device.
• We do not sell your data and we do not show ads.
• We collect basic usage analytics that do not include your voice or the text you practise.

What stays on your device

• Your practice history, scores, streaks, saved sentences and words, and app settings.
• Your voice recordings during practice. Echo uses the microphone and Apple's speech recognition to score what you say. When your device supports on-device speech recognition, Echo asks for it to be used, so your audio is processed on the device. On devices or languages without on-device support, Apple may process speech on its servers under Apple's own terms and privacy policy.
• Translations and optional AI sentence splitting, which use Apple's on-device Translation and Apple Intelligence features where available.

Information sent to services

Videos you import

When you paste a YouTube link, Echo contacts YouTube from your device to get the video details, captions and audio it needs to build a practice. That request is made directly between your device and YouTube, and YouTube handles it under its own terms and privacy policy.

Suggested videos

Echo's suggested videos come from a small server we run. Your device asks it for a list of videos. We do not ask for your name or an account, and the list does not depend on who you are. Like most servers, our hosting provider may keep standard technical logs, such as IP address and request time, for security and reliability.

Word lookups

When you tap a word to see its meaning, Echo sends that word to the Free Dictionary API (freedictionaryapi.com) to fetch definitions, synonyms and antonyms.

Analytics

Echo uses PostHog, hosted in the EU, to count how features are used, for example when the app is opened, when a practice is created or when a daily goal is reached. Events describe actions and simple numbers such as the length of a practice. They do not include your voice, your recordings, or the text of the sentences you practise. We do not use session replay and Echo does not show ads.

Subscriptions

Echo Pro is bought through Apple. We use RevenueCat to check whether you have an active subscription and to restore purchases. RevenueCat receives purchase information and an anonymous app user ID. We never see your payment details; Apple handles payment.

iCloud backup

If you turn on iCloud backup, Echo stores a backup of your history in your own iCloud account, protected by Apple. We do not have access to it.

Permissions Echo asks for

• Microphone: to hear you during shadowing practice.
• Speech recognition: to score your speech and to generate transcripts from imported audio.

You can change these at any time in the iOS Settings app.

How long we keep information

On-device data stays until you delete the app or the data. Analytics events are kept for as long as they are useful for improving Echo. You can ask us to delete analytics data linked to you by emailing us.

Children

Echo is a general audience learning app and is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has given us information, contact us and we will delete it.

Your choices and rights

You can delete your on-device data by deleting the app, revoke the microphone and speech permissions in iOS Settings, and turn off iCloud backup. Depending on where you live, you may have rights to access, correct or delete personal information we hold. Email us and we will help.

Changes to this policy

If we change this policy we will update the date at the top of this page. If a change is significant we will make it clear in the app or on this page.
