Privacy Policy

Introduction

At Cella (developed by roundhill.io), we take your privacy seriously. This Privacy Policy explains how we collect, use, and protect your information when you use our mobile application.

Cella is designed with privacy as a core principle. Our app processes data locally on your device using Apple's on-device AI technology, ensuring your personal information stays private.

Information We Collect

Local Data

• Notes, journal entries, and chat conversations you create
• Photos, videos, documents, and other files you attach to your entries
• Tags and organizational data you add to your content
• App usage data for improving functionality (stored locally)

iCloud Data (Optional)

If you choose to enable iCloud sync, your data will be encrypted and stored in your personal iCloud account. We do not have access to this data.

How We Use Your Information

• To provide and maintain the Cella app functionality
• To process your data locally using on-device AI
• To sync your data across your devices (only if you enable iCloud sync)
• To improve app performance and user experience

Data Storage and Security

Your data is stored locally on your device and is protected by your device's security features. All AI processing happens on-device, ensuring your conversations and content never leave your device unless you explicitly choose to sync via iCloud.

We implement appropriate technical and organizational security measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction.
