# Privacy Policy for Shimmr

Updated Nov 2, 2026

## We Don’t Store Your Personal Data

Our app does not collect, store, or share any of your personal data. All data is stored locally on your device, and we have no access to it.

## Anonymous Data Collection

While we do not collect personal information, we track anonymous app events to enhance user experience and improve functionality. These events contain no personally identifiable information (PII) and help us understand how users interact with the app.

## Tracked Anonymous Events

- **Audio Start & Finish** - Tracks when an audio session starts and ends, including preset ID and session duration
- **Favorite Preset** - Tracks when a user favorites or unfavorites a preset
- **Mixer Modifications** - Tracks changes such as volume adjustments, reverb settings, tone volume, noise volume, and equalizer selection
- **Timer Usage** - Tracks usage of the default and preferred timer settings
- **Refocus Sounds** - Tracks selection, start, and stop actions, including refocus sound choices and interval adjustments
- **Screen Settings** - Tracks when the “Keep Screen Awake” setting is toggled
- **Mix with Other Apps** - Tracks when the “Mix with Other Apps” setting is toggled
- **Restart Timer** - Tracks when the timer is reset or restarted

## How This Data is Used

The anonymous data we collect is used exclusively for:

- ✓ Improving app performance by identifying bottlenecks and optimizing functionality
- ✓ Enhancing user experience by understanding how features are used and making improvements accordingly
- ✓ Fixing issues and crashes based on aggregated app usage patterns

This data is completely anonymous, meaning it cannot be traced back to an individual user, device, or account. We do not collect personal details, email addresses, IP addresses, or unique device identifiers. The information gathered is purely statistical and helps us make data-driven improvements to the app.

## No Data is Shared with Third Parties

We do not share, sell, or transmit any collected data to third parties, advertisers, or external services. The analytics data is strictly used internally to enhance app performance and provide a better user experience.

## Analytics Tools

We use Firebase Analytics to collect anonymous data. Firebase Analytics helps us understand app usage patterns and improve features. No personally identifiable information (PII) is collected through Firebase.

## Newsletter (Optional)

You can sign up for our newsletter on this website, if you want to. It is separate from the app and entirely optional. Nothing in Shimmr depends on it.

- **What we collect:** your email address, plus where you signed up (for example an article or the home page) and the language of the page.
- **Why:** to send you occasional emails about Shimmr, such as new journeys and sounds. Only after you confirm your address by tapping the link in our first email.
- **Who handles it:** our email service, Kit (kit.com), a US company that stores and sends the emails for us. We do not sell or share your address with anyone else.
- **How long:** until you unsubscribe. Every email has an unsubscribe link, or write to [hi@shimmr.app](mailto:hi@shimmr.app) and we will delete your address.
- **Legal basis:** your consent (GDPR Article 6(1)(a)), which you can withdraw at any time.

## Privacy Policy Updates

This Privacy Policy may be updated periodically. Any changes will be reflected on this page. We encourage users to review it from time to time.
