Ohmie Privacy Policy

Effective date: June 30, 2026

Ohmie ("the app") is an educational app for learning electronics, published by the Ohmie team.

Ohmie has no accounts, no ads, and no cross-app tracking. The only data that leaves your device is (1) what's needed to manage your subscription, and (2) starting in v1.3, anonymous product-analytics events. Both are explained below.

What stays on your device

Your progress and preferences — XP, coins, streak, completed lessons, your display name, and reminder/exam-date settings — are stored only on your device using Apple's standard app storage. We never see them, and deleting the app deletes them.

Subscriptions

Ohmie offers an auto-renewing subscription with a free trial. Purchases are processed by Apple and managed through RevenueCat, our subscription provider. To know whether you have an active subscription, RevenueCat receives your purchase and transaction details along with an anonymous, app-generated identifier. This is not tied to your name or any account (there is none), and it is never used for advertising or tracking.

• RevenueCat privacy policy: https://www.revenuecat.com/privacy
• Purchases are also subject to Apple's privacy policy.

Anonymous product analytics

Starting in v1.3, Ohmie uses PostHog for anonymous, aggregate product analytics — so we can see which parts of the app people use and where they get stuck, and make it better. We send a small set of usage events (for example, "lesson completed" or "paywall shown"), each tagged with an anonymous, app-generated ID and basic device info (device model, OS version, app version, locale). No personal data is collected — no name, no email, nothing you type. Your IP address is discarded (so no location), there is no advertising identifier, and your data is never used for advertising or cross-app tracking.

What we do not do

• No accounts, sign-up, or login.
• No advertising and no ad identifiers (no IDFA).
• No cross-app tracking, and no selling or sharing of data with data brokers.
• No access to your camera, location, contacts, photos, or microphone.

Notifications

If you enable reminders, scheduling happens entirely on your device. We never see it.
