Privacy Policy

Effective October 13, 2026

Linguanda ("the app") is provided by Zetage Technologies LLC, 30 N Gould St Ste N, Sheridan, Wyoming 82801 ("we", "us"). This policy explains what information the app handles and why. Questions: [email protected].

The short version

• Your learning progress, settings and the name you type stay on your phone.
• You only need an account for AI voice conversations, and you sign in with Apple. We do not ask for your name or email.
• When you talk to the AI partner, your voice is processed by outside AI services to understand you and to answer. We do not keep your recordings or transcripts.
• Kid Mode has no ads and no tracking.

Information stored on your phone only

Your chosen language, level, vocabulary progress, streaks, settings and the name you type during setup are saved on your device. They are not sent to us.

Information we collect when you use AI conversations

• Sign in with Apple. Apple gives the app a sign-in token. We verify it with Apple and keep only a scrambled (hashed) identifier derived from your Apple user ID. We do not request or receive your name or email address.
• A usage log. For each AI conversation we record when it started, the language and scenario, and your plan (free or premium), so we can apply the free limit.
• Technical data. Our servers briefly see your IP address and request details to protect the service from abuse (for example, limiting how many requests one device can make).

Your voice and the AI services

When you speak to the AI partner, the app sends your recording to our server, which passes it to service providers that work for us:

• Fish Audio converts your speech to text and turns the AI's reply into spoken audio.
• SiliconFlow runs the language model that writes the AI's reply from the conversation text.

We do not store your recordings or transcripts on our servers. These providers process the data under their own terms and privacy policies, and may retain it as those policies describe. Do not say anything in a conversation that you would not want a service provider to process.

Subscriptions

Premium purchases are handled by Apple. We use RevenueCat to confirm whether a subscription is active; it receives purchase information and an anonymous identifier. We never see your payment details.

Advertising

Free accounts in the standard (adult) mode may see ads served by AppLovin. Ad providers may collect device identifiers and usage data to show and measure ads. On iPhone, the app asks for your permission before any tracking, and you can change your choice in Settings > Privacy & Security > Tracking. Premium users and Kid Mode never show ads.

Children

Kid Mode is designed for children to use together with a parent or guardian. It contains no advertising and no third-party tracking. The only feature that sends a child's voice to outside services is the AI voice conversation, which requires signing in with an Apple ID and, in Kid Mode, a parent PIN entered by a grown-up before each conversation. We do not knowingly collect personal information from children under 13 without verifiable parental consent. If you believe a child has given us personal information, contact us and we will delete it.

How long we keep information

The usage log and plan record are kept while your account exists and are deleted when you delete your account. Delete your account in the app (Profile > Delete Account) or follow the steps on our delete account page.

Where information is processed

Our servers and database are in the United States. Service providers named above may process data in other countries.

Your rights

Depending on where you live (for example, the EU/UK or California), you may have the right to access, correct or delete your information, or to object to some processing. Because we keep very little, deleting your account removes what we hold. To make a request, email [email protected].

Security

Connections between the app and our servers are encrypted, and our service keys are kept on the server, not in the app. No system is perfectly secure.

Changes

If we change this policy we will update the date above and, for significant changes, tell you in the app.
