Privacy Policy
How English Exercises uses data for learning progress, accounts, analytics, and site operations.
English Exercises in ChatGPT
Charles Daniel Crowley operates English Exercises and its ChatGPT plugin. This section describes the plugin; the sections below describe the wider website.
The plugin receives your search topic, optional level and selected exercise identifier to find and open existing exercises. These inputs are processed for the duration of the request; the plugin server does not save them in an account, database or application log. An English Exercises account is not required. Avoid putting personal information in a search topic.
Answers and scores are checked in the embedded player and retained only in its temporary page state, until that player is restarted or unloaded. The integration does not send your answers or score to our MCP server, save account progress or send results back to the chat model.
Cloudflare hosts the server, player and exercise files and processes technical request information, such as IP addresses, user agents and security events, to deliver and protect them. Hosting and security records are subject to Cloudflare’s applicable retention practices, separate from the temporary exercise state. See Cloudflare’s privacy policy.
When browser storage is available, standard site-visit analytics may record a browser session identifier, page path, referrer and visit date, as described below. Browser preferences and identifiers remain until you clear that site’s browser storage; the ChatGPT sandbox may make storage unavailable. Opening our website from the plugin uses the website features and data practices described below.
You can restart the player to discard its current answers, clear available site storage through your browser, or disconnect the plugin in ChatGPT. To ask about access, correction or deletion of data held by English Exercises, email [email protected]. Your conversation and data held by ChatGPT are governed separately by OpenAI’s privacy policy; use ChatGPT’s data controls for those records.
Core Exercises Without an Account
You can use the main exercise library without signing in. Anonymous progress is stored in your browser and may also use a session ID so progress can be linked if you later create an account.
Optional Account Features
If you sign in, account data can be used for saved progress, XP, streaks, profiles, leaderboards, level-test results, notifications, and paid features where available.
What We Collect
Exercise progress
Exercise attempts, answers, scores, completion status, time spent, streaks, XP, and level-test results.
Account details
If you sign in, we may receive your email address, display name, avatar, authentication identifiers, and profile settings.
Analytics events
Product events such as sign-in, exercise answers, downloads, private-lesson CTA clicks, page path, referrer, device type, and country-level signals.
Advertising signals
Where advertising is enabled, ad vendors may process ad impressions, approximate location, device information, consent choices, cookies, or similar identifiers.
Contact and teacher flows
If you send a private-lesson enquiry, we process your name, email address, and message so that Charlie can reply. Contact, embed, homework, or teacher features may also process assignment data, participant display names, and referrers.
Technical data
Browser storage identifiers, user agent, hosting logs, security logs, and request metadata needed to operate and protect the site.
Private-Lesson Enquiries
If you use a private-lesson enquiry form, we send your name, email address, and message to Charlie so that he can answer your request. Resend processes the message on behalf of English Exercises. Your email address is used as the reply address and is not automatically added to a marketing list.
Enquiries are kept only for as long as reasonably needed to reply, manage the potential lesson relationship, and meet any applicable legal obligations. You can ask us to access, correct, or delete your enquiry details by emailing [email protected].
Browser Storage
The site uses browser storage for functionality and progress. Local progress can be sent to our database when you sign in so your work can be saved to your account.
- Theme preference
- Anonymous exercise session ID
- Local exercise progress and prompt state
- Sign-up source and conversion prompts
- Authentication session and effective user ID when signed in
- Country preference, homework tokens, display names, and local audio practice data where features are used
- Advertising consent choices and advertising cookies or similar storage where ads are enabled
Analytics and Improvement
We use analytics to understand which exercises work, where learners struggle, and whether account or private-lesson flows are functioning. Analytics may be associated with an anonymous session or a signed-in user.
Analytics events can include learning interaction data, such as the exercise, question, selected answer, correct answer, completion state, timing, page path, referrer, country-level signal, and device type.
Advertising and Consent
English Exercises may show Google AdSense ads on selected public exercise pages. Ads are not intended to appear inside answer controls, account areas, payment pages, homework pages, embeds, or utility pages.
Third-party vendors, including Google, may use cookies or similar technologies to serve ads based on visits to this site or other sites, measure ad performance, limit repeated ads, and detect invalid activity. Google's advertising cookies enable Google and its partners to serve personalised or non-personalised ads depending on your choices and applicable law.
For visitors in the European Economic Area, the UK, and Switzerland, we use a Google-certified consent message for advertising consent where required. You can consent, reject, or manage options in that message. If you reject advertising consent, Google may serve non-personalised or limited ads, or no ads, depending on the available consent signals and Google's ad-serving rules.
You can also manage Google advertising preferences at Google Ad Settings. Browser controls can also clear or block cookies, though blocking some storage may affect site features.
Third-Party Services
These services help run the site, process accounts, store progress, provide analytics, and support paid or media features where they are offered.
- Cloudflare: Pages, Functions, CDN, security, request metadata, and R2 storage for supported audio assets.
- Neon: PostgreSQL database for accounts, profiles, progress, analytics, and app data.
- Supabase Auth: Sign-in, Google OAuth, email magic links, session management, and authentication tokens.
- Google AdSense: Advertising on selected public exercise pages. Google and its partners may use cookies or similar technologies to serve and measure ads, subject to consent requirements where they apply.
- Stripe: Checkout, subscription, customer, and entitlement data where paid features are offered.
- Unsplash and image providers: Some images may be loaded from third-party image hosts.
- YouTube: Some learning pages may embed videos or load video thumbnails.
- Azure Speech and audio providers: Speech or audio features may use text-to-speech, transcription, or audio generation providers where available.
- Google OAuth: Google may provide account identity details if you choose Google sign-in.
- Resend and email providers: Private-lesson enquiries and direct emails are processed by Resend or the email services used by you and English Exercises. Enquiry details are used to answer your request, not to subscribe you to marketing.
Paid and In-Progress Features
Some Fluency Gym and audio features are still in development. Where paid features are offered, payment card details are handled by Stripe rather than stored by English Exercises. We may store subscription status, Stripe customer identifiers, checkout metadata, and entitlement records so paid access works.
Audio or speech features may use Cloudflare R2 storage and speech/audio providers. Practice recordings may also be stored locally in your browser where those features are available.
Your Choices
You can use most free exercises without an account. You can clear local browser storage in your browser settings to remove anonymous local progress from that device. If you sign in, you can sign out from the account menu.
Where the advertising consent message is shown, you can use its Manage options control to review or change advertising choices available for your region.

What We Do Not Do
We do not sell personal data or use payment card details outside the payment processor. Advertising, where enabled, is limited to selected public exercise pages and is described above.
