Altworld/Privacy Policy

Privacy Policy

Last updated: July 6, 2026

The short version: we collect what the game needs to run, we never sell your data, payments live with Stripe, and the AI providers that power turns process the text you type in-game.

What we collect

We collect the minimum needed to run the game:

  • Account data: your email address, display name, and a salted hash of your password (we never store the password itself). If you sign in with Google, we receive your email and basic profile from Google instead.
  • Gameplay data: your runs, turns, characters, worlds, saves, and the actions you type — this is the game state itself.
  • Billing data: if you buy Candles or a subscription, payment is processed by Stripe. We store your Stripe customer reference and purchase history, never your card number.
  • Technical data: session cookies to keep you signed in, and privacy-focused aggregate analytics (page views, performance) via Vercel Analytics.

How AI processing works

Altworld is an AI game: the actions you type and relevant world state are sent to large-language-model providers (such as OpenAI or providers accessed through OpenRouter) to resolve turns and generate narration. This content is processed to run your game and is subject to those providers' data-handling terms. Don't include personal information you wouldn't want processed this way in your in-game actions.

Cookies and advertising

We use essential, httpOnly session cookies to keep you signed in — these are not tracking cookies.

Some pages may show ads through Google AdSense. Google and its partners may use cookies to serve and measure ads; you can manage ad personalization at adssettings.google.com.

Emails

We send transactional emails only — verification, password resets, and important account notices — via the Resend email service. We don't sell your email address or send marketing you didn't ask for.

Public content

Worlds you choose to publish, along with your display name as the author, are public and may appear in search engines. Unpublished runs and drafts stay private to your account.

Data retention and deletion

We keep your account and gameplay data while your account is active. To delete your account and associated personal data, contact us on Discord (linked in the footer) from the account in question, and we will process the deletion.

Children

Altworld is not directed at children under 13, and we do not knowingly collect personal information from them.

Changes and contact

If this policy changes materially, we'll update the date above. Questions about your data are answered fastest on our Discord server, linked in the footer of every page.
