Your Security Matters

Privacy-First Architecture

Your thoughts deserve the highest level of protection. We've built Reflect Day with security and privacy as core principles, not afterthoughts.

Zero-Knowledge Design

Your journal entries never touch our servers. Data flows directly between your device and your personal cloud storage—we can't read your thoughts even if we wanted to.

Your Cloud, Your Rules

Sync via your personal Google Drive in a private app folder. You own, control, and can export your data anytime. No vendor lock-in, ever.

Private AI Integration

Use your own Gemini API key for AI chat, tag extraction, and cover image generation. Your conversations stay between you and Google—we never see them.

Local Encryption

Optional device-level encryption with your own password. We never store encryption keys—only you can decrypt your thoughts.

Session-Free Security

No persistent sessions significantly reduce session hijacking risks. Fresh authentication each time provides an additional security layer.

Minimal Third Parties

No backend means no data processing on our end. You connect your own Google Drive (via Google's App Settings API) and your own Gemini API key. We only use trusted services for weather/location context—never your journal content.

Security-First Means Some Tradeoffs

We've chosen security over convenience in key areas:

What This Means for You

  • You'll need to sign in with Google each time you open the app
  • You would have to enter a password for local encryption (we never store this key - only you know it)
  • AI features require your own Gemini API key (one time setup, free tier available)

What You Get in Return

  • Complete data ownership and privacy
  • No risk of data breaches from our side
  • Full control over AI interactions and data sharing
Important Notice

Security Transparency

While we follow security best practices, this app has not undergone third-party penetration testing just yet. Like any software, there's always a risk of unknown defects that could potentially allow bad actors or malware to access user data. We're committed to transparency about our current security status.

Common Questions

Frequently Asked Questions

Everything you need to know about your data, privacy, and how Reflect Day works

No, Reflect Day is not a medical device or therapeutic tool. It's a personal journaling application designed to help with reflection and self-expression.

While many users report wellbeing benefits from regular journaling, Reflect Day should not be used as a replacement for professional healthcare or therapy. If you're experiencing mental health challenges, please consult with a qualified healthcare provider.

You do, 100%. Your data is exclusively yours. We designed Reflect Day with a "zero-knowledge" architecture.

Your journal entries and media never pass through our servers. Data only circulates between your Google Drive account and your devices (via the web app or mobile applications).

We literally cannot access, read, or own your data because it never touches our infrastructure. This privacy-first approach ensures complete data ownership and control remains in your hands.

Reflect Day uses your personal Google Drive account as the synchronization mechanism. When you write entries, they're stored locally on your device first, then synchronized directly to your Google Drive.

When you use Reflect Day on another device, it reads directly from your Google Drive.

Since your data is synchronized with Google Drive, you can always recover your journal by installing Reflect Day on a new device and signing in with your Google account.

For additional security, we recommend setting up two-factor authentication on your Google account.

Absolutely. Reflect Day allows you to export your entries. Your data is never locked into our system.

Reflect Day uses Google Drive's App Settings API, which creates a dedicated, secure space that only this app can access.

This approach provides three important benefits:

  • Enhanced privacy - Your journal entries are completely isolated from other apps and cannot be accidentally accessed.
  • Clean organization - Your Google Drive remains uncluttered as journal entries are stored in this special area rather than your main Drive folders.
  • Limited access - Reflect Day can only access its own dedicated directory and cannot read any other files you store in Google Drive, further protecting your privacy.

Your data remains yours and is securely stored in your Google account, but in a dedicated section specifically for Reflect Day's use.

This is intentional for your security. Reflect Day stores the Google authentication credentials in session storage, which is a temporary browser storage mechanism.

Session storage is automatically cleared when you close the browser tab or exit the PWA on your smartphone, requiring you to authenticate again when you return.

Since Reflect Day is built without a server component (for maximum privacy), there's no other secure place to store these credentials long-term. This approach ensures that even if someone gains access to your device, they can't access your journal without also having access to your Google account.
