Privacy Policy

Last updated: August 16, 2026

Overview

Kou is an offline-first app. Reading the calendar requires no account, no login, and no personal data. The one exception is the optional Full Edition purchase, which is handled by Apple and a purchase-processing service called RevenueCat, described below.

What We Collect

We do not collect, store, or transmit any personal information. The app:

• Runs entirely on your device for all reading and browsing
• Contains no analytics or advertising tracking
• Does not require an account or login
• Does not store your reading history or preferences on any server

Your Data

All your interactions with the app — which seasons you view, any notes you make — stay on your device. You own this data completely. If you delete the app, all local data is deleted.

Purchases (Full Edition)

If you choose to buy the Full Edition, the purchase is processed by Apple's App Store and by RevenueCat, a service that verifies purchase receipts on our behalf so this app doesn't have to handle payment details itself.

Making a purchase involves:

• Apple processing the transaction and payment — Kou never sees or stores your payment information
• RevenueCat receiving a receipt from Apple and an anonymous, app-generated device identifier, so it can confirm the purchase and unlock the Full Edition — this identifier is not tied to your name, email, or Apple ID
• No browsing activity, reading history, or personal details being shared with RevenueCat or Apple beyond what's needed to confirm the purchase itself

You can review RevenueCat's own privacy policy at the link above for further detail on how they handle this data.

Third-Party Services

The app does not integrate with any advertising networks or data brokers. Apple (for payment processing) and RevenueCat (for purchase verification) are the only third parties involved, and only for users who make the optional Full Edition purchase.
