Privacy & Security

Let's talk about something most productivity apps would rather you didn't think about: what happens to your data.

Your task manager knows a lot about you — what you're working on, what you're stressed about, when you're most productive, what your goals are. Most apps treat all of that as data to monetize. We think that's a problem.

Clairvoyant was built on a simple principle: your productivity data should be private by default, not by promise.

Your Data Lives on Your Device​

Unlike most productivity apps, Clairvoyant doesn't need the cloud to function. Everything lives on your device first.

  • Works fully offline - Create tasks, manage your calendar, take notes — all without internet
  • Sync is optional - Cloud backup is there for multi-device access, but it's not a requirement
  • Everything's instant - No waiting for server round-trips

When you do enable sync, your data is encrypted before it ever leaves your device. The cloud is a backup, not the source of truth.

We Can't Read Your Data​

By default, Clairvoyant uses zero-knowledge encryption. Your data is encrypted on your device before it ever leaves. The server stores encrypted data it literally cannot read. Not us, not our engineers, not anyone.

  • End-to-end encrypted - Data is encrypted on your device before syncing
  • We never have your keys - Your encryption keys are derived from your password, which we never see
  • No backdoors - Not for us, not for governments, not for anyone
  • Your password is your key - Only you can decrypt your data

Even if Clairvoyant's servers were compromised, hacked, or subpoenaed — your encrypted data would remain unreadable. That's the whole point.

Optional: Server-Assisted AI​

If you want more powerful AI features without running models on your own hardware, you can opt in to Server-Assisted AI. Here's what that means:

  • Our server temporarily decrypts your tasks in memory only to run AI features, then discards the plaintext immediately
  • Your data is never stored unencrypted, never logged, and never used for training
  • We run our own AI models on our own servers — your data never touches OpenAI, Google, or any third-party AI provider
  • You can revoke access at any time from Settings and return to full zero-knowledge mode

This is an explicit opt-in. It's never enabled without your consent. Learn exactly how Server-Assisted AI works →

No Tracking​

  • No usage analytics by default
  • No behavioural tracking — we don't watch what you click or how you use the app
  • No data sales - Your information is never sold or shared
  • Crash reports are opt-in - Disabled by default, with personal info scrubbed out

You Own Your Data​

Where It Lives​

  • On your device - Tasks, notes, and settings stored locally
  • Encrypted in the cloud - Only if you enable sync, always encrypted at rest
  • Your call - You decide whether to sync, and you can delete cloud data anytime

What We Don't Store​

  • Your browsing history
  • Usage analytics
  • Personal information beyond what you explicitly give us
  • Third-party tracking data

Export & Delete​

  • Export everything - Download all your data as JSON, whenever you want
  • Delete everything - Wipe all cloud data with one action
  • No retention tricks - When you delete, it's actually gone

Third-Party Integrations​

When you connect services like Google Calendar or Microsoft Outlook, we use one-way sync — your events come in, but nothing goes back out. Your tasks, notes, and Clairvoyant data never leave your control.

For self-hosted services like CalDAV/Nextcloud, two-way sync is available since you own the server.

Open Source​

Don't take our word for any of this. Clairvoyant is open source — you can inspect the encryption implementation, verify our privacy claims, and audit the entire codebase yourself.
