Privacy

Solvelingua is a game for learning a language by talking. This page says what it keeps about you, why, and who else handles it. Last updated 22 October 2026.

What we keep

• Your game. Each character is saved on our servers under a save code: progress, money, belongings, the people you've met, and what you've said to them, so they can remember you.
• Your account, if you make one. Your email address, and if you sign in with Google, your Google account's id and email. We don't get your Google password, contacts or anything else from your Google account. An account lists your save codes so you can play them on any device.
• A sign-in cookie, so you stay signed in for up to 60 days. We use no advertising or tracking cookies.

What we do with it

We use it to run the game and nothing else. We don't sell it, share it for advertising, or use it to profile you.

Who else handles it

• Cloudflare hosts the game and stores saves. Its AI models write the characters' replies, give feedback and turn your voice into text. Cloudflare also sends our sign-in emails.
• ElevenLabs gives the characters their voices, and handles the audio of voice calls in the game.
• Google signs you in, if you choose to sign in with Google.

What you type or say in a conversation goes to these services so the game can answer you.

Your choices

You can play without an account. You can sign out at any time from the game's menu. To have your account or your saves deleted, or to ask what we hold about you, email privacy@solvelingua.com and we'll do it within 30 days.

Children

Solvelingua isn't meant for children under 13, and we don't knowingly keep their information.
