Privacy

Thank you for choosing Lazulite. Your privacy is important to us, and we are committed to safeguarding your personal data. This Privacy Policy outlines the types of information we collect, how we use it, and the measures we take to protect your data when you use our Android application available on the Google Play Store.

Website Analytics:

When you visit lazulite.app, we use Umami to collect anonymized analytics about page visits and interactions with download links, setup resources, FAQ answers, and contact links. This analytics applies only to the website and is separate from the optional telemetry collected by the Android app. Umami does not use cookies or identify individual visitors. Umami analytics data is processed on servers in the European Union and retained only for as long as necessary to improve the site and its support content, and to meet applicable legal obligations, in accordance with applicable privacy laws.

We also use the Google Ads tag to measure advertising performance using Google Consent Mode. Advertising storage, analytics storage, advertising user data, and ad personalization remain denied on every page. The tag does not read or write advertising or analytics cookies, and ad click identifiers are redacted from measurement requests. Google still receives cookieless measurement requests containing page and browser information; cookieless does not mean that no data is sent. Google processes this information under its Privacy Policy.

Android App Diagnostics:

Crash diagnostics are optional and disabled by default. If you choose to enable Crash diagnostics during onboarding or in Settings, Lazulite may send crash reports and technical diagnostic logs to Firebase Crashlytics, a Google service. These reports can include technical information about the app, device, operating system, and events leading to a problem. We do not describe them as anonymous because technical information can sometimes be identifying when combined with other information.

Crashlytics may retain reports locally while diagnostics are disabled. If you later enable Crash diagnostics, locally stored reports may upload to Firebase Crashlytics. Turning the setting off stops Lazulite from sending diagnostic breadcrumbs immediately and disables Crashlytics collection for future app runs; it does not delete reports already held by Firebase.

System Logs: Users have the option to send us system logs to assist in resolving technical issues. While these logs can provide valuable information for troubleshooting, they may also contain sensitive information about the user’s device. Sending system logs is entirely voluntary.
Destination Device Vendor Lookup: When the optional “Look up destination vendor” setting is enabled, Lazulite sends the first three pairs of your connected Bluetooth device’s MAC address to MACLookup to identify its vendor. This setting is on by default when no preference has been saved, and existing choices are preserved. You can turn it off in Settings. No other part of the address is ever sent.

How We Use Your Information:

Troubleshooting: Crashlytics reports and system logs aid us in identifying and rectifying technical issues to ensure smooth app performance.

Optional User Questionnaires:

Lazulite may occasionally show you optional questionnaires about your audio setup and listening experience. Answering is entirely up to you, and you can dismiss them whenever you want without any effect on the app. If you do respond, your answers (which may include free-text comments) are sent over a secure connection to a third-party survey service so we can understand how Lazulite performs on real devices and setups.

We only collect the answers you submit. Survey responses are completely anonymous: they carry no device identifiers, account info, or other personal data. We use them in aggregate for research and product improvements.

Optional Device Diagnostic Captures:

Lazulite may invite you to share a diagnostic capture when we have not yet collected one for your device model and Android version. Sharing is entirely optional. The capture is sent privately to the Lazulite team and used only to improve Lazulite. It is separate from questionnaires and Crash diagnostics and does not change either setting.

A capture contains the full diagnostic export from the refresh shown on Home, including device and Android information, Bluetooth logs, media metrics, and available audio and routing logs. It may contain device names, Bluetooth addresses, playback apps, track details, and other identifiers. These captures are not anonymous. Service providers involved in private delivery and storage process the capture on our behalf.

We do not publish or sell these captures, or distribute them to third parties for their own use. Only the manufacturer, model, and Android major version may be added to our public device catalog after manual review. Dismissing the invitation or successfully sharing a capture stops further invitations on that installation, including after Android upgrades. Captures are not saved on your device for later background sending.

We do not sell or trade your information. If you enable Crash diagnostics, Google Firebase Crashlytics receives and processes those diagnostics. See Google’s Privacy Policy for information about Google’s data practices. When destination vendor lookup is enabled, MACLookup receives the partial MAC address needed to identify the vendor. You can check MACLookup’s own privacy practices for details on how it handles that data. If you answer an optional questionnaire, the survey service receives only the answers you submitted.

Data Protection:

We implement a variety of security measures to maintain the safety of the data we collect. While we strive to protect your information, no method of electronic storage is 100% secure, and we cannot guarantee its absolute security.

Your Choice and Contact:

Crash diagnostics are optional. You can enable or withdraw them at any time in Lazulite under Settings → Crash diagnostics. Questionnaire participation is optional too, and you can skip it at any time. For privacy questions or requests, contact us at [email protected].

Changes to This Privacy Policy:

We may update our Privacy Policy from time to time. Any changes will be posted on this page, and we advise you to review this page periodically for any changes.
