Privacy Policy

Last updated: June 7, 2026

PolyglotGym ("we", "us") operates the language-learning platform at polyglotgym.com. This policy explains what data we collect, why, and what choices you have. Questions and requests: [email protected].

What we collect

Account data. Email address and a hashed password when you register, plus your chosen interface and study languages.
Learning activity. Exercise results, course progress, points, streaks, achievements, vocabulary reviews, and similar gamification data. We use this to run the product: track your progress, schedule reviews, and award achievements.
Voice recordings. If you use pronunciation exercises, your microphone audio is processed to score your pronunciation. Recordings are used for scoring, not for advertising and not to train AI models.
AI feature inputs. If you use AI features (conversation practice, writing feedback), the text you submit is sent to our AI model providers to generate a response and counted against your usage credits.
Payment records. Purchases (premium membership, dialect courses) are processed by Stripe. We never see or store your card number; we store the purchase record (what was bought, when, for how much).
Technical logs. IP addresses and request metadata in server logs, used for security, rate limiting, and abuse prevention. Log retention is short and capped.

Cookies and analytics

Essential cookies keep you signed in and remember your language preferences. These are required for the site to work.
Analytics (Google Analytics 4) runs in cookieless mode: consent for analytics storage is denied by default (Google Consent Mode), so no analytics cookies are set on your device. We receive only aggregate, cookieless usage signals (pages visited, approximate region) to help us improve the product. If you prefer to block even these pings, the Google Analytics opt-out browser add-on covers them as well.

Service providers

We share data only with the processors needed to run the service:

Stripe — payment processing.
ElevenLabs — text-to-speech generation of course audio (course text only, no personal data).
AI model providers — processing of the text you submit to AI features, to generate responses.
Google — site analytics (GA4).
Hetzner — hosting; servers are located in the EU.

We do not sell personal data and we do not show third-party advertising.

ChatGPT app and public discovery tools

PolyglotGym exposes public, read-only discovery tools (for example via our ChatGPT app and the public MCP endpoint at /mcp). These tools only return links to public course, grammar, vocabulary, and word-list pages. They cannot access accounts, learner progress, or any private data. Requests to these endpoints are rate-limited and logged (IP-derived client key, tool name, timing) for abuse prevention only.

Your rights

You can access, correct, export, or delete your data. You can export your data directly from your profile; deletion is handled as a support request and removes your personal data from our active systems (records we must keep for legal reasons, such as payment records, are retained in anonymized form). To exercise any of these rights, email [email protected]. If you are in the EU/EEA, you also have the right to lodge a complaint with your local supervisory authority.

Children

PolyglotGym is not directed at children under 16. We do not knowingly collect personal data from children.

Changes

We will update this page when our practices change and adjust the date above. Material changes will be announced in the product.
