Privacy Policy

The Short Version

We believe privacy is a fundamental right, especially for something as personal as mental wellness. Here's what you need to know:

• The Euno app collects no data. No accounts, no analytics, no telemetry.
• This website collects only your email if you join the waitlist.
• We don't use cookies or any tracking technologies.
• We will never sell your data because we don't have any to sell.

What We Collect

On This Website

If you join our waitlist, we collect:

• Email address: So we can notify you when Euno launches.
• Platform preference (optional): Whether you're interested in iOS or Android, if you choose to tell us.

That's it. We don't store IP addresses, browser information, or any other personal data. (To prevent abuse of the signup form, a salted hash of your IP is held briefly in server memory for rate limiting — it's never written to the database and can't be reversed into your address.)

In the Euno App

The Euno iOS app collects nothing. Zero. It:

• Has no user accounts
• Sends no analytics or telemetry
• Makes no network requests
• Works entirely offline
• Stores all data locally on your device

Calendar Access

Euno can optionally read your device's calendar to choose a more relevant affirmation on days with important events. This feature is strictly opt-in — the app never asks for calendar access during setup, and declining it changes nothing about how the app works. When enabled, all processing happens on your device: no calendar data is uploaded, stored, or transmitted anywhere, because there is no server to send it to. You can revoke calendar access at any time in your device's system settings.

Journaling

Journal entries are encrypted and stored only on your device. They are never synced, transmitted, or readable by us. If you export your journal, the export is also encrypted.

How We Use Your Email

If you join the waitlist, we use your email only to:

• Send a confirmation that you've joined
• Notify you when Euno launches on the App Store
• Send rare, critical updates (if any)

We will never:

• Send marketing emails or newsletters
• Share your email with third parties
• Use your email for advertising purposes

Cookies and Tracking

This website does not use cookies, pixels, analytics scripts, or any tracking technologies. We don't use Google Analytics, Facebook Pixel, or any similar services.

Data Storage and Security

Waitlist emails are stored in a secure PostgreSQL database hosted on Railway (a US-based cloud provider). We use industry-standard security practices to protect this data.

Your Rights

You can unsubscribe from the waitlist at any time using the link in any email we send. If you want your email completely removed from our database, email us at [email protected] and we'll delete it within 48 hours.

For Users in the EU and California

If you're covered by the GDPR or the CCPA, you have specific rights around your personal data — including the right to access, delete, or port it, and the right to know exactly what's being collected. Because Euno collects almost nothing, most of these rights are already satisfied by default. The only personal data we store is your email address if you join the waitlist, and we'll delete it on request. For any data-related questions or requests, email [email protected].

Third-Party Services

We use the following services:

• Postmark: To send transactional emails (welcome, launch notification)
• Railway: To host our website and database
• Cloudflare: For DNS and security

These services may have access to your email address solely for the purpose of delivering our emails or hosting our infrastructure. They are bound by their own privacy policies.

When the app launches, subscription purchases will be processed through Apple's App Store and potentially a subscription management service. We'll update this section with specifics before launch.

Changes to This Policy

If we make significant changes to this policy, we'll update the date at the top of this page. We won't start collecting more data without telling you first.
