This app installs at no charge. To use its features you need the in-app unlock - a Pro subscription (EUR 2.99/month) that renews automatically until cancelled and can be cancelled anytime in Microsoft Store settings, or a one-time purchase. All features require this purchase.

How the subscription works

free + Pro EUR 2.99/mo

What we don't collect

• Any content you enter into the app (notes, logs, data) — it stays on your device unless you explicitly sync.
