Emily GPT is a toy hamster you can talk to. We built it to keep what you say on your phone. There are no accounts, no ads, no analytics and no tracking, and we never sell data.
By default Emily thinks with "Mini AI", a small model that runs entirely on your phone. Your messages don't leave the device.
If you choose another brain in Settings (for example OpenAI, Anthropic, Google Gemini or another online service) and enter your own key, the app asks your permission first. After you agree, your messages go straight from your phone to that service and are handled under its privacy policy. We never see them. Keys and settings are stored only on your device.
If you choose "Emily Cloud", the app asks your permission first. Your messages then pass through our server to Anthropic's Claude, which writes Emily's reply. Our server doesn't store them; it keeps only short-lived counters (by network address and a random app ID) to stop abuse. Anthropic handles the messages under its commercial terms and does not use them to train its models.
The microphone is only used while you hold the talk button. Speech is turned into text on your phone; audio is not recorded, stored or sent to us.
To give Emily her voice, the text of her replies is sent to Microsoft's speech service, which returns the audio. It isn't linked to you.
The camera is only used when you tap Place to put Emily in your room. Camera frames are processed on your phone and are not stored or sent to us.
On Android, this application runs on Google Play Services for AR (ARCore), which is provided by Google LLC and governed by the Google Privacy Policy. On iPhone and iPad it uses Apple's ARKit, which runs on the device.
If you report something Emily said, we receive the reply, the message before it, the reason you picked, any note you add, which brain was used, your platform and the time. We use reports only to make Emily safer and delete them after 90 days.
The first time you use Mini AI or voice, the app downloads model files from public hosts (Hugging Face and jsDelivr). Like any download, those hosts see your IP address.
Emily is designed to stay kind and family-friendly and blocks romantic, sexual and self-harm topics. We don't knowingly collect personal information from children. If you believe a child has sent us a report containing personal information, email us and we'll delete it.
You can deny microphone or camera access and still chat by typing. Uninstalling the app deletes everything it stored on your phone. To ask about or delete a report, email d@worldbuild.io.
If this policy changes we'll update it here and change the effective date.
