Privacy Policy
Last updated: January 2025
At Isshin, we believe your focus and intentions are deeply personal. That's why we've built an app that respects your privacy by design.
1. We Collect Zero Data
Isshin does not collect, store, or transmit any of your personal data.
Your daily intentions, focus history, settings, and all other app data remain entirely on your Mac. We have no servers storing your information. We cannot see what you're working on—ever.
2. Local-First Architecture
Everything happens on your device:
- Your intentions are stored locally
- Your history never leaves your Mac
- Your settings stay on your machine
- No cloud sync, no external servers
This means your data is always under your control. Delete the app, and your data goes with it.
3. Beta Waitlist
If you sign up for our beta waitlist on this website, we collect your email address solely to:
- Send you beta access invitations
- Notify you when Isshin launches
You can unsubscribe at any time, and we will delete your email upon request.
4. No Analytics, No Tracking
The Isshin app contains no analytics, no tracking pixels, and no telemetry. We don't know how many times you open the app, what you type, or how you use it.
5. No Third Parties
We do not share any data with third parties because we don't have any data to share. Your privacy is not a feature—it's the foundation of how Isshin is built.
6. Changes to This Policy
If we ever change our privacy practices, we will update this page and notify beta users via email.
