Privacy Policy

1. Scope and controller

This Privacy Policy applies to the Turbo Lingua mobile app, public website, support pages and related account services.

The Turbo Lingua operator is responsible for the service. Privacy requests must be submitted through the support page.

2. Information we may collect

Account data: name, email address, password credentials in protected form, sign-in provider, account status and session information.

Learning data: selected interface language, learning language, level, module progress, completed exercises, review history, streaks and local app settings.

Technical and advertising data: device type, operating system, app version, IP address, device or advertising identifiers where available, consent choices, app and ad interactions, diagnostics, network requests, error logs, security events and approximate region derived from technical infrastructure.

Purchase data: selected subscription product, store, transaction and entitlement status, purchase and expiration dates, renewal status and whether the purchase is a test transaction. Turbo Lingua does not receive complete payment-card details from the app store.

Support data: email address, request topic, message text, screenshots or files voluntarily attached by the user.

3. Audio, microphone and speech practice

Turbo Lingua uses pre-generated audio for phrase playback. Audio files may be cached locally on the device after first playback to improve speed and reduce repeated network use.

Microphone access is requested only for speaking, pronunciation or speech-recognition features. Users can deny or revoke microphone permission in device settings.

Speech recognition may rely on device or platform services available on the user's operating system. Turbo Lingua should not be used to record sensitive personal information during practice.

4. Why we use data

We use data to create and secure accounts, provide language practice, sync progress, play audio, remember settings, process and restore Premium access, show and measure advertising in the free plan, record consent choices, send password reset or account emails, respond to support requests and improve reliability.

We may also use limited technical data to prevent abuse, investigate errors, protect the service and comply with legal obligations.

5. Legal bases for EEA and UK users

Depending on the feature, processing may be based on contract necessity, user consent, legitimate interests such as security and product reliability, or legal obligations.

Where processing depends on consent, such as optional microphone permissions or certain communications, consent can be withdrawn through app, device or account settings where available.

6. Service providers

Turbo Lingua may use trusted providers for hosting, storage, email delivery, analytics-free operational logs, authentication and platform services.

Providers may include Cloudflare for hosting, storage and API infrastructure; Gmail API or another email provider for account email; Google or Facebook for optional social sign-in; Google Play for app distribution, billing and subscription management; RevenueCat for purchase validation and Premium entitlement management; and Google AdMob and its consent platform for advertising in the free plan.

Providers may process data only as needed to provide their services, protect infrastructure, comply with law or follow their own user-facing terms when a user chooses a third-party sign-in provider.

7. Advertising, sharing and sale of data

Turbo Lingua does not sell personal information in the ordinary meaning of selling user data for money.

The free plan may show ads provided by Google AdMob. Depending on the user's region, age signals, consent choice and device settings, ads may be personalized or non-personalized. Ad technology providers may process or share IP addresses, device or advertising identifiers, app interactions, ad interactions and diagnostic information to deliver, limit, secure and measure ads.

Where required, Turbo Lingua requests advertising consent before initializing ads and provides access to privacy choices. Premium users do not receive in-app advertising while Premium access is active.

8. Retention

Account and synced progress data are kept while the account is active or as needed to provide the service. Local cached files remain on the device until the app or cache is cleared.

Support messages and attached files should be kept only as long as needed to resolve the request, maintain records, prevent abuse or meet legal obligations.

9. Security

Turbo Lingua uses reasonable technical and organizational measures such as encrypted transport, restricted access, server-side checks and protected authentication flows.

No app or online service can guarantee absolute security. Users should protect their account credentials and avoid sharing sensitive information through support messages or screenshots.

10. International transfers

Service providers and infrastructure may process data in countries other than the user's country. Where required, appropriate safeguards should be used for international transfers.

11. User rights

Depending on location, users may have rights to access, correct, delete, export or restrict the use of personal information, object to certain processing, withdraw consent and lodge a complaint with a data protection authority.

California residents may have rights to know, delete, correct, limit use of sensitive personal information and opt out of certain sale or sharing. Turbo Lingua does not currently sell personal information.

Requests can be made through the support page. We may need to verify the account or request before acting on it. Advertising consent can also be reviewed through the privacy options made available in the app where required.

12. Children

Turbo Lingua is intended for users aged 16 and over and is not directed to children. If a parent or guardian believes a child provided personal information, they should contact support.

Age ratings, child-directed settings and store requirements are reviewed as required by applicable app store rules and law.

13. Changes

This policy may change as Turbo Lingua evolves. Material changes should be reflected on this page and, where appropriate, inside the app.
