Privacy Policy

Last updated: 2026-09-24

quine runs as an Android app and in your web browser (the browser version is served from this website). This policy explains what happens to your data in both. It is written to be plain and honest, not to be exhaustive legalese.

No backend, no account, no analytics

quine has no server operated by its developer. There is no account and no login, and quine contains no analytics and no third-party tracking. The "worlds" you create and your conversations with the assistant are stored on your device only:

• in the Android app, in the app's private files;
• in the browser, in this website's private storage inside your browser (the Origin Private File System). Clearing this site's data in your browser deletes them.

This website is static files hosted by GitHub Pages. Like any web server, GitHub receives your IP address when your browser loads it; see the GitHub Privacy Statement. The quine developer receives no data from this.

Your OpenRouter API key

The assistant runs on an AI service reached through OpenRouter, using your own OpenRouter API key.

• In the Android app, the key is encrypted on your device with AES-GCM under a non-extractable key held in the Android KeyStore, and only the encrypted result is stored, in the app's private preferences.
• In the browser, the key, the chosen model and the reasoning effort are stored in this website's local storage in your browser. That storage is not encrypted; anyone with access to your browser profile can read it. Remove the key in quine's Settings page or clear this site's data to delete it.

The key is used only to talk to OpenRouter on your behalf. It is never written to your worlds, your conversations or logs.

What is sent to the AI service

When you use the assistant, the following are sent to OpenRouter and the AI model provider you selected, so they can generate a response:

• your messages to the assistant,
• the content of the world the assistant is working on, including images of quine's own screen that the assistant looks at,
• any photo you choose to attach.

In the browser, these requests go directly from your browser to OpenRouter. This data is handled under the privacy policies of OpenRouter and the respective model provider; see OpenRouter's privacy policy. The quine developer does not receive or store it.

Photos

A photo you select is decoded and resized on your device, and its image bytes are sent as part of the AI request to OpenRouter. The conversation stored on your device keeps only the text; the image bytes are not stored.

Web access

The assistant can load web pages and call web services on your behalf, for example to look something up for an app it builds for you. Those websites receive the request and your IP address, under their own privacy policies. In the Android app this can be switched off in Settings; web search additionally works only with a search server you configure yourself. In the browser, such requests are sent by your browser and only reach sites that allow it.

Speech input

A world can ask you to speak instead of type. In the Android app this uses your device's speech recognition service, which needs the microphone permission and may process the audio on your device or on the servers of its provider (usually Google), under that provider's privacy policy. quine receives only the recognised text, and it listens only while that world is visible on your screen.

Children

quine is not directed at children.
