## 1. We Do Not Collect Your Data
**We do not collect, store, or transmit any personal data or usage data from you.**
- We do not collect your name, email, phone number, or any other identifying information.
- We do not collect usage analytics, crash reports, or device identifiers for tracking.
- We do not sell, rent, or share any data about you because we do not collect any.
Your notes and data stay on your device (and, if you use them, your own cloud accounts) under your control.

## 2. Data Stored on Your Device
The App may store data locally on your device (e.g., notes, settings, preferences). This data remains on your device and is not sent to our servers. We do not have access to it.
---
## 3. Backup (Google Backup and iCloud)
The App may use your device’s or operating system’s backup features so you can restore your data when you reinstall or switch devices:
- **Google Backup (Android):** If you have backup enabled, your Android device may back up app data (including notes and settings) to your Google Account. This is governed by Google’s privacy policy and your Google account settings. We do not control, access, or receive this backup data.
- **iCloud (iOS):** If you use iCloud backup or app-specific iCloud storage, your app data may be stored in your iCloud account. This is governed by Apple’s privacy policy and your iCloud settings. We do not control, access, or receive this backup data.
Backup data is held by Google or Apple under their respective terms and privacy policies. We encourage you to review [Google’s Privacy Policy](<https://policies.google.com/privacy>) and [Apple’s Privacy Policy](<https://www.apple.com/legal/privacy/>) to understand how your backup data is handled.

## 4. Third-Party Services
The App may use third-party services that have their own privacy practices:
- **App stores (Apple App Store, Google Play):** If you make in-app purchases, the store may process payment and account information according to its own privacy policy. We do not receive or store your payment details.
- **RevenueCat (or similar):** If we use a service to manage subscriptions or entitlements, that service may receive anonymous or hashed identifiers necessary to validate your purchase. We do not use such services to track or profile you.
We encourage you to review the privacy policies of any such third parties.

## 5. Children’s Privacy
The App is not directed at children under 13 (or the applicable age in your region). We do not knowingly collect any personal information from children. If you believe a child has provided us with personal information, please contact us and we will take steps to delete it (to the extent we hold any, which we do not by design).
---
## 6. Changes to This Policy
We may update this Privacy Policy from time to time. We will post the updated policy with a new “Last updated” date. Continued use of the App after changes constitutes acceptance of the updated policy.
