Privacy Policy

Last updated October 1, 2026

Lamp is a Bible-learning app. This policy explains what Lamp collects, why, and the choices you have. Lamp does not show ads and does not sell your information.

Without an account

You can use Lamp without an account. Your progress, highlights, notes, and memory verses are stored only on your device.

With an account

If you create an account, Lamp stores your username, a securely hashed password, a hashed recovery code, and your study data (progress, streak, XP, highlights, notes, memory verses, reading plan, and settings) so it can sync between your devices.

Study groups

If you join a study group, other members can see your username, streak, XP, reading-plan progress, memory-challenge progress, when you last read, and anything you post on the group board.

Ask and chapter questions

When you use Ask, your question (and the verse or step you asked about) is sent to Anthropic, which provides the AI model that writes the answer. Under Anthropic's commercial terms, these requests are not used to train its models by default. Chapter questions are generated from the Bible text only, not from your data.

Scripture and usage reporting

Bible text is provided by API.Bible (American Bible Society). As their license requires, Lamp reports which passages are viewed using anonymous device and session identifiers. This does not include your name, username, or account.

Reminders

If you turn on daily reminders, Lamp stores the notification address for your device and the time you chose. In the iPhone app, reminders are scheduled on your device.

Purchases

Lamp Plus is purchased through Apple. Lamp never sees your payment details. Purchase status is handled by RevenueCat, which links your purchase to your Lamp username.

Service providers

Lamp runs on Cloudflare, which processes requests (including your IP address) to deliver the app. Other providers are API.Bible (Scripture), Anthropic (Ask), RevenueCat (purchases), and the Free Use Bible API (cross-references, which receive only the chapter being viewed).

Deleting your data

You can delete your account at any time in Settings → Account → Delete account. This permanently deletes your account and synced study data and removes you from your study groups. Posts you made on a group board remain visible to that group unless you remove them first. Data stored only on your device can be cleared in Settings → Progress → Reset all progress.

Children

Lamp is not directed to children under 13 and does not knowingly collect their personal information.
