Privacy Policy

Last updated: October 23, 2026

Overview

Focusnest ("the App") is an ambient sound mixer for iOS and Android, designed to help you focus, relax, and sleep. This policy explains what data the App collects and how it is used.

Data We Collect

The App uses Google Analytics for Firebase to understand how the App is used so we can improve it. It collects:

• App interactions, such as which sounds are turned on, volume changes, presets applied or saved, timer use, screens viewed and Pro purchases
• An app instance identifier generated by Firebase, and basic device information such as model, OS version and language
• Approximate region (country or city level) derived from your IP address

This data is not linked to your name, email address or any account, and is not used for advertising. Google processes it on our behalf as a service provider. See Firebase privacy information.

Website

This website (focusnest.buildgeeks.dev) uses Google Analytics to measure how visitors find and use it. It collects pages viewed, clicks on the App Store and Google Play buttons, the campaign parameters in the link you arrived from (such as utm_source and utm_content), and basic browser and device information. Google signals and ad personalization are turned off, and this data is not used for advertising. When you tap a store button, the campaign parameters are passed to the App Store or Google Play so we can see which campaign led to an install. See how Google uses this information.

Data Stored on Your Device

• Your presets, mix, volume settings and timer preferences are stored only on your device
• No account creation is required

Purchases

Focusnest Pro is purchased through the Apple App Store or Google Play. Payment is handled entirely by Apple or Google; we do not receive your payment details.

Audio Content

• All sounds are bundled within the App. No internet connection is required to play them
• Sounds come from public domain (CC0) recordings or were created with AI audio generation tools

Sharing

We do not sell your data or share it with third parties, other than Google acting as our service provider for analytics as described above.

Support Requests

If you contact us through our support page, we receive the email address and message you send, and use them only to reply to you.

Your Choices

Analytics data is retained according to the data retention settings of Google Analytics. To ask us to delete data associated with your device, contact us via our support page.

Children's Privacy

The App is not directed to children under 13 and does not knowingly collect personal information from them. The App contains no user-generated content or social features.

We may update this privacy policy from time to time. We will notify you of any changes by posting the new policy on this page.
