This page covers the Language1 website and the Language One iOS app: what we store to run the game and keep rankings fair, and what our ad partner collects in the iOS app.
Account data
You can play without an account. If you sign in, we may store your email, the name your identity provider shares, optional profile fields you provide, and authentication identifiers returned by the identity provider. Sign-in runs through Amazon Cognito with Google or Apple. Your email is used for account identity and is not meant to be edited in-app.
Other players see you by your username, never by your name or email. Every account starts with a random username, and you can change it at any time under Account → Profile.
Sign in with Apple
When you sign in with Apple, Apple shares your name the first time you sign in, plus your email. If you choose Hide My Email, we receive an Apple relay address instead of your real email, and Apple forwards any mail to you.
Gameplay data
We may store prompts, LLM guesses, target challenge metadata, attempt counts, token counts, elapsed time, model information, and leaderboard projections. Anonymous users are intended to stay out of public leaderboards. Clues and guesses, without your account details, may also be used to study how well language models understand human clues.
Security and abuse prevention
We may store IP address data to enforce anonymous play limits, reduce cheating, debug reliability issues, and protect the service. Anonymous identifiers stored in your browser or in the app may also be used for play continuity.
If you report a game or race, we record that you reported it, using your account or guest identifier, so our team can review it.
Ads in the iOS app
The iOS app shows ads from Google AdMob between games to cover model costs. The website has no ads. To show and measure ads, Google may collect your device's advertising identifier (only if you allow tracking), an app-specific device identifier, IP address, approximate location derived from it, device and app information, and how you interact with ads. Google describes how it uses this data at policies.google.com/technologies/partner-sites.
Your ad choices
After your first finished game, the app asks for your choices. In the EEA, the UK and Switzerland, Google's consent form asks whether your data may be used for ads. iOS then asks whether Language One may track you across other companies' apps and websites. If you decline, you still see ads, but they aren't based on your activity elsewhere. You can change the tracking choice at any time in iOS Settings → Privacy & Security → Tracking. In those regions you can change your consent choices at any time from Settings → Ad privacy choices in the app.
Third-party services
Authentication and infrastructure run on AWS. Clues are sent to the selected model provider (Together AI or Amazon Bedrock) to get the model's guess. Ads in the iOS app are served by Google AdMob. Avoid submitting sensitive personal information in prompts.
Deleting your data
You can delete your account from inside the website or the iOS app: sign in, open Account → Profile, and choose Delete account. This removes your profile, your sign-in, and your leaderboard rankings right away. Clues and guesses you played may be kept without your account details, as described under Gameplay data.
If you can't sign in, email [email protected] from the email on your account and we'll delete it for you. If you signed in with Apple using Hide My Email, include your username so we can find your account.
