Lore Privacy Policy

Updated October 27, 2026

ProtoductAI Inc. (ProtoductAI株式会社, “we”) handles information in the iOS and Android app “Lore” and in the MCP server that connects AI to Lore as described below.

Information we handle

• Account: email address, user identifier and profile name
• Content sent to Lore: articles, images, sources, tags and quizzes
• Learning records: read and favorite status, answers and study sessions
• Notifications: notification settings and the device identifier used to deliver them
• Purchases: your Lore Pro subscription status and purchase history, received through Apple, Google and RevenueCat (we never receive your card details)
• Usage: in-app interaction events (such as app opens, articles opened, whether a quiz answer was right and purchases started), the user identifier that links them, and a random identifier the app creates on your device for analytics. They never include article or quiz content or your email address
• What you write when you contact us

How we use it

To authenticate you; store, display and sync your content; keep your learning history and choose review questions; send notifications about new deliveries; verify your Lore Pro subscription, which decides whether the app and AI connections are available; handle incidents and support requests; and improve the app by analyzing how it is used. We do not use it for advertising or to track you across other companies’ apps or websites.

Service providers

Clerk handles sign-in (including Sign in with Apple and Google), Convex stores data and images, Apple delivers push notifications and processes payments, Google processes payments in the Android app, RevenueCat manages subscriptions, Cloudflare runs the AI connection (the MCP server), and PostHog, Inc. (USA) provides usage analytics. Each processes information only as needed to provide these functions and may do so outside your country, including in the United States. RevenueCat receives your Lore user identifier and purchase information. PostHog receives only in-app interaction events, your user identifier and the random identifier created on your device, which we use only to analyze and improve the app. External images in articles are loaded from their hosts. We do not sell personal information.

Connecting AI

The app itself does not research or generate content with AI. Only after you sign in to your Lore account in an AI’s screen (such as Claude or ChatGPT) and approve the connection can that AI read your articles and quizzes and create or update them. Information passed to the AI is governed by that AI provider’s privacy policy. You can remove the connection at any time in the AI’s connector settings. We do not use your content to train AI.

Retention and deletion

We keep information while your account is active. You can turn off notifications in Settings. Archiving hides an article from lists and does not delete it. Signing out does not erase data on the server.

Request deletion of your Lore data with “Delete account” (in Settings, or in the menu at the top right of the purchase screen). Once the request is accepted, access stops, your Lore data—articles, images, quizzes, learning history, tags and notification destinations—is deleted in stages, and you are signed out on this device. The account you sign in with (your authentication account) is not deleted, because other ProtoductAI apps use it too; contact us if you want it deleted. You can also request deletion without the app as described on the data deletion page. To remove the AI connection, disconnect Lore in your AI app (such as ChatGPT or Claude). Deletion records are kept for 31 days so that restores from backups do not bring deleted data back, then erased. Backups for incident recovery are kept for up to 30 days. Copies in our providers’ backups are erased under each provider’s retention policy.

Purchase records may remain with Apple, Google and RevenueCat for accounting and fraud prevention. Contact us if you want your RevenueCat records deleted. Deleting your account does not cancel your App Store or Google Play subscription.

Your rights

To access, correct, stop the use of or delete your information, or to get a copy of it, contact us at the address below. We verify your identity and respond as required by law. Depending on where you live, you may also complain to your data protection authority.
