Privacy Policy

Last updated: 2026-11-11

This policy explains how the developer of EnglishR (“we”) handles information in the EnglishR mobile app for iOS and Android (the “App”) and on this website. Questions: edsolutions.studio@gmail.com.

1. Your data stays on your device

We don't collect or store personal data on our servers. The App keeps the following only on your device:

• Study progress, saved words, settings (language, voice, theme), saved channels and videos, and your AI API key, AI history and voice chat transcripts.
• Photos and documents you add to “My content”, and the text recognised in them. Text recognition runs on the device.
• The date the App was first opened, used on the device so each device gets the 7-day free trial once. On iPhone and iPad it is kept in the device's secure storage (Keychain) so reinstalling doesn't restart the trial; it is never sent to us and contains nothing about you.
• A copy of the App's purchase history, read from Apple or Google on the device to unlock your subscription.

Uninstalling the App deletes this data from the device, except the first-open date in the Keychain mentioned above.

Backups. If you turn on your phone's own backup (Android backup to your Google account, iCloud on iPhone and iPad), it may include App data. That backup is kept in your own account, we can't see it, and you control it in your phone's settings. You can also export a backup file in the App's Settings and keep it wherever you choose; that file leaves out your AI key, AI history and “My content”.

2. Subscriptions

Subscriptions (monthly or yearly, auto-renewing) are bought through Apple's App Store or Google Play, which handle payment and renewal under their own terms and privacy policies (Apple, Google). You can cancel at any time in your store account settings. The App checks the transaction records the store provides on your device. We never see your name, payment card or store account.

3. Features that connect directly to other services

Some features work by connecting your phone straight to a third-party service. We don't receive, see or store what is exchanged; that third party's privacy policy applies.

• AI features (optional) — use the provider you choose (OpenAI, Google Gemini or DeepSeek) with your own API key. What you ask — your question, the text or picture you pick, a video's subtitles, or a podcast's audio when you ask for a transcript — is sent from your phone to that provider. Don't send personal information to the AI.
• Voice chat with AI (optional) — uses Google Gemini with your own API key. During a call, your voice from the microphone is streamed from your phone to Google, which replies by voice and transcribes both sides. We don't receive it. The App keeps the text transcript on your device and doesn't save the audio. The microphone is used only during a call and after you allow it.
• In-app browser — the pages you open load directly from those sites. Like any website, they can see your IP address and may use cookies. Looking up words on a page happens on your phone.
• YouTube — videos, subtitles and the latest uploads of channels you follow load from YouTube (Google) under Google's Privacy Policy.
• Podcasts — feeds and audio load directly from each show's publisher, which can see your IP address; episodes may contain the publisher's own ads. When you search for a show, your search words go to Apple's podcast directory.
• Document scanning — uses Google Play services' document scanner on Android and Apple's scanner on iPhone; images are processed on the device. The camera is used only when you tap scan and after you allow it.
• Pronunciation and shadowing practice — the front camera can be shown as a mirror, and the microphone can record you saying a word or sentence to play it back or to check it with the device's speech recognition (on-device where the device supports it). Nothing is recorded to storage, uploaded or kept; camera and microphone are used only when you tap the button and after you allow them.
• Read-aloud uses your device's built-in text-to-speech.

4. Anonymous usage statistics

To learn which features are useful and what to improve, the App sends anonymous statistics through Google Firebase Analytics: which screens are opened (without their content — e.g. “a word page”, not which word), a few events (finishing or skipping the first-launch questions, with the goal, level and minutes a day chosen; buying a plan; how often AI is used and with which provider), the App language, trial / subscribed status, and the technical data Firebase collects itself (App and OS version, device model, country estimated from the IP address, a random id for this installation).

It never sends your name, email, anything you type or search, your AI questions, API key, photos or documents. No advertising identifier (IDFA / Advertising ID), no ads, no ad personalisation. Google processes this data as described in the Firebase privacy information.

Turn it off at any time: Settings → “Send anonymous usage statistics”. When off, the App sends nothing more and deletes the statistics not yet sent from the device.

When it opens, the App downloads a small setting from Google Firebase Remote Config, to learn whether a new feature needs an update. This uses a random Firebase installation ID, sends none of your study data or content, and runs even when statistics are turned off.

About twice a day, when online, the App checks englishr.web.app (Google Firebase Hosting) for new learning content (vocabulary, grammar, pronunciation lessons...) and downloads it if there is any: automatically on Wi-Fi (you can turn this off in Settings → Learning content), and only after asking you when on mobile data. This only downloads files and sends none of your study data or content; like any website, the server can see your IP address.

5. When you contact us

If you email us, we use your email address and what you write only to reply, and keep the conversation only as long as needed to help. Ask and we'll delete it.

If you message us on Messenger, the messages are handled under Meta's policies. We use them only to reply to you.

6. This website

This website is static pages hosted by Google (Firebase Hosting). It uses no cookies, no analytics and no forms. Google processes technical data such as your IP address to deliver the pages (Firebase privacy information).

7. Children

The App is a learning tool with no ads and no social features; we collect no personal information from anyone, including children. If you are a parent and believe your child sent us personal information (for example by email), contact us and we'll delete it.

8. Your rights and choices

You can turn the AI features off at any time by removing the key in Settings, and turn anonymous usage statistics off in Settings too. Because we keep no data about you on a server, there is nothing for us to access, correct or delete there; uninstalling the App deletes the data on your device. For purchase records, contact Apple or Google.

9. Changes

We may update this policy. If we add a feature that stores data on a server of ours, we will update the policy before it goes live. The “Last updated” date above shows the current version.
