## What is Opal?

Opal: A Diary That Lasts Forever

In a world of fleeting apps and data-hoarding services, Opal redefines digital journaling. We're not here to own your words—we're here to set them free. Designed with privacy and simplicity at its core, Opal ensures your diary endures, no matter what. Whether the app evolves or the world changes, your entries remain yours, readable in any text editor—forever.

Why Opal? Privacy Without Compromise

Your Data, Your Control
Every entry lives locally on your device or synced securely to iCloud. We never access, store, or scan your private thoughts. No ads, no tracking, no servers—just pure, unfiltered privacy.

Timeless Portability
Entries are saved in open Markdown format, so your diary is never locked in. Export, migrate, or open them in tools like Obsidian, Notion, or even a basic text editor. If Opal ever sunsets, your story doesn’t.

Effortless Writing, Deeper Reflection

Minimalist Magic
A clean, serene interface strips away the noise so you can focus on what matters—your thoughts.

AI-Powered Weekly Reflection
Turn your entries into meaningful insights with optional weekly summaries. Use your favorite AI provider—including Apple Foundation Models—to reflect on your week while keeping your data under your control.

Opal isn't just an app; it's a commitment to longevity. We've built something that honors your voice for generations—perfect for writers, thinkers, and anyone who values their inner world.
