Privacy Policy

Earhart · updated 23 October 2026

Earhart is an invite-only iOS app that turns Wikipedia articles into podcast episodes. It is run by Luca Loncar as a small private beta. This page says what Earhart collects, why, who else sees it, and how to delete it.

What Earhart collects

• Account: your name, email address and profile picture from Google (or the email address of an account we set up for you), and the invite code you redeemed.
• What you make and do: the episodes you ask for and their settings, your conversations with Amelia (typed, and the text of voice conversations), notes, thumbs, star ratings and voice notes you leave on episodes, and where you are in each episode so you can pick up on another device.
• How you listen: a history of your listening, linked to your account: when you open the app and an episode, when you play, pause, skip or scrub and from where (the app, the lock screen, AirPods), how far you get, playback speed, and when playback waits or fails. The admin reads it to see what works in Earhart and what doesn’t. It is not shared with anyone else or used for ads.
• Device: a push-notification token if you turn on “Ready to listen”, and the app build number.
• Diagnostics: crash and error reports (Sentry), tagged with your account id only.

Earhart has no ads, does not track you across other apps or websites, and does not sell data.

Microphone and speech recognition

The microphone is used only while you talk to Amelia or dictate a message, and only after you tap the mic. Dictation uses Apple’s speech recognition. Voice conversations with Amelia stream your voice directly to Google Gemini for the length of the conversation; Earhart keeps the text of what was said, not the audio. Voice notes left by older builds are stored as audio and transcribed.

Outside AI services

Amelia and the episodes are made with AI services run by other companies. Before you first use Amelia, the app asks for your permission to send them:

• Meta (Muse model): your typed messages to Amelia and the chat history, to write her replies. Meta may use these requests to improve its models.
• Google (Gemini): your voice and the conversation so far, during a voice conversation with Amelia.
• OpenAI: voice notes, to transcribe them.
• Anthropic, Meta, DeepSeek and voice models we host: the Wikipedia article and episode settings, to write and voice an episode. These requests contain the topic you chose, not your name or email.

None of these services receive your name or email address from Earhart.

Where it is stored

Your account and data are stored with Supabase (database, sign-in and file storage). The API runs on Vercel, the episode worker on Fly.io and Modal. Sign-in uses Google. Push notifications go through Apple. Crash reports go to Sentry.

Who can see your episodes

Your episodes, notes, ratings and conversations are private to you. Notes and ratings are your feedback to the Earhart team: the admin reads them to improve the show and fix problems. The admin may make an episode public in the app’s Public tab, where other invited listeners can hear it; your notes and ratings on it stay private.

Keeping and deleting your data

Your data is kept while you have an account. In the app, Settings → Account → Delete account deletes your account, your private episodes, notes, ratings, voice notes, conversations, listening history and devices straight away. Episodes that were made public stay up for other listeners without your name on them. Crash reports expire after 90 days. You can also email lucaloncar@gmail.com to ask for a copy of your data or to have it deleted.

Children

Earhart is not meant for children under 13 and does not knowingly collect their data.
