Privacy Policy

1. Who we are

The Manxn app is provided for smart fragrance device control. For privacy questions, data requests, or deletion requests, contact us at manx36331@gmail.com.

No account is required to use the current app. We do not ask you to register, log in, or provide a name or phone number.

2. Information we handle

The current Google Play Android release, version 0.1.4, and Apple iOS release, version 1.0, have no configured diagnostics or feedback-upload endpoint. They do not transmit diagnostics, crash logs, feedback, feedback images, Bluetooth identifiers, or local settings off the device.

The entries below distinguish information processed locally, information processed by the official website, and information that would be transmitted only if a later app release enables a diagnostics service. We will update Google Play Data safety and Apple App Privacy disclosures before enabling such a service.

Local app settings, such as selected devices, custom device names, schedule settings, fragrance oil estimates, language choice, and optional local device images. These are stored on your device.
Bluetooth device information needed for discovery and connection, such as device names, connection state, signal and service status, and app-generated hashed device identifiers.
If diagnostics are enabled in a later release: anonymous diagnostics, including app version, operating system version, device model, app language, anonymous installation ID, session ID, scan/connect/write failures, recent app state, and related troubleshooting logs.
If diagnostics are enabled in a later release: crash logs, including stack traces and technical error details from a previous app crash.
If feedback upload is enabled in a later release: user-submitted feedback, including the problem description you type and any optional feedback images you choose to attach.
If feedback upload is enabled in a later release: optional JPEG, PNG, or WebP images selected by you for support purposes. Each image is limited to 5 MB.
Basic website and server information needed to deliver pages, downloads, diagnostics, and security protections, such as request time and network metadata processed by our hosting environment.

3. Information we do not collect

We do not sell personal data.
We do not use advertising, cross-app tracking, behavioral advertising, or advertising SDKs.
We do not collect precise GPS coordinates or upload precise location.
We do not automatically collect contacts, photos, files, clipboard contents, payment information, or account credentials.
We do not create cloud accounts or bind fragrance devices to a cloud user profile in the current app version.

4. App permissions

On iPhone and iPad, Bluetooth permission is used to discover, connect to, and control compatible fragrance devices.
On iPhone and iPad, the system photo picker opens only when you choose a local device image. The app receives only the selected image and stores it locally.
On Android, Bluetooth and nearby-device permissions are used to discover, connect to, and control compatible fragrance devices.
On some Android versions, location permission and Location Services are required by Android for Bluetooth Low Energy scanning. We use this permission only to scan for nearby Bluetooth devices; we do not collect or upload precise location.
If Bluetooth Low Energy scanning cannot work because Location Services are turned off, the app may guide you to Android system Location Settings so you can turn Location Services on. This step is only to let Android permit Bluetooth scanning; it does not mean we collect or upload your location.
The current mobile releases do not send diagnostics or feedback. When you select a legal or support link, your browser opens the official website.
Photo or file access is used only when you actively choose a local device image or a supported attachment. The app does not scan your photo library or files automatically.

5. How we use information

To discover, connect to, and control fragrance devices.
To save local preferences and schedules on your device.
To diagnose Bluetooth scanning, connection, notification, and command-write failures.
To investigate crashes, compatibility issues, and user-submitted support requests.
To protect the diagnostics service from abuse and keep the official website available.
To improve app stability and device compatibility.

6. Sharing and third parties

We do not sell personal data and we do not share data for advertising or tracking. We may process diagnostics and feedback through our own website server and infrastructure providers that host or secure the service. We may also disclose information if required by law, to protect users, or to respond to valid legal requests.

The current app does not include third-party advertising, analytics, push notification, payment, map, or social-login SDKs. If we add any SDK that changes data handling, we will update this policy and the app store data disclosures before release.

7. Security

We use reasonable technical and organizational measures to protect diagnostics and feedback, including transport security where available, private server-side attachment storage, request validation, and access controls for diagnostic administration.

No method of transmission or storage is completely secure. Please do not include sensitive personal information in feedback descriptions or feedback images unless it is necessary for support.

8. Data retention and deletion

Local settings remain on your device until you change them, clear app data, or uninstall the app.
Anonymous diagnostics and feedback records are retained only as long as needed for troubleshooting, security, legal, and product reliability purposes. Our operational target is to delete or anonymize routine diagnostics within 24 months unless a longer period is needed for an active support, security, or legal matter.
You can request deletion of diagnostics or feedback you submitted by emailing us at manx36331@gmail.com. Because the app does not use accounts, please include the approximate submission time, app language, device model, and any support details that help us locate the record.
If you remove app permissions or uninstall the app, future Bluetooth access, diagnostics, and feedback uploads stop unless you reinstall or grant permissions again.

9. International processing

Your information may be processed in the country or region where our website, diagnostics service, hosting provider, or support workflow operates. We handle the information according to this Privacy Policy regardless of processing location.

10. Children's privacy

The app is intended for fragrance device control and is not directed to children. We do not knowingly collect personal information from children. If you believe a child has provided personal information, contact us at manx36331@gmail.com and we will take appropriate action.

11. Changes to this policy

We may update this Privacy Policy when app features, permissions, diagnostics, support workflows, or legal requirements change. The updated page will show the effective date.
