Metronomaybe keeps your music practice on your device. You decide what to record, import, export or include in feedback.
1. Who this policy covers
Neverplain Works operates neverplain.cc and develops Metronomaybe for Android (cc.neverplain.metronomaybe). This policy covers both.
2. What stays on your device
The app stores your metronome designs, sound settings, stickers, practice plans, titles and composers, score ranges, tempo goals, practice history, notes, recording markers, MaybeHen progress and language preferences locally. These records are used to provide the features you choose.
Selected cover and sticker photos are processed locally using Android’s file picker; the app does not scan your photo library. Plan covers retain a resized source image and framing settings for re-editing. Photo stickers retain the cropped image and its shape, placement and attachment settings, rather than the original file. These images may be included in your manual backups.
The reviewed Android release has no internet permission, advertising or analytics SDK, automatic crash-reporting SDK, account or developer-operated cloud sync. Its interface and sounds are bundled. It does not transmit your practice records, photos or recordings to the developer. Android, Google Play or a file provider may separately process information under their own settings and policies; this policy does not describe that as app-operated collection.
App records and recordings use Android’s private app storage, rather than a public website folder. Access is subject to Android’s app isolation and your device security. The app provides no separate password encryption for its database or exported files.
3. Microphone and recordings
Microphone access is requested when you choose to record. It is used to save that practice recording as an AAC audio file in the app’s private storage. A recording can contain voices or other sounds nearby. The app does not automatically upload recordings.
Recording from the floating metronome also requires your explicit action. Ordinary in-app recording stops when you leave the app; recording started in the floating window can continue while that window and its microphone foreground service remain active. Android provides the applicable microphone/service indicators. Stop using the recording controls or revoke microphone access in Android Settings; other practice features remain available.
4. Floating window and background playback
The optional floating metronome asks Android for permission to display a small control window over other apps. It does not read the sheet music, screen contents or other apps beneath it, and does not capture your screen. You may revoke this permission in Android Settings.
If you enable background and lock-screen operation, a foreground service and wake lock support metronome playback and practice timing, including timing with the metronome off. The service provides a notification with a stop action; its display is subject to Android permissions and settings. These functions do not send data to a server.
5. Files you choose to import or export
You can export a recording or a ZIP backup to a destination chosen with Android’s file picker. Backups can contain your collection, practice history, notes, photos and recordings. The app does not encrypt exported files with a separate password. Keep them somewhere you trust.
A cloud drive or other destination you select handles exported files under its own terms and policy. After confirmation, restoring a backup replaces the current practice database and imports the backup’s recordings. It does not erase all older recording files; remaining files may appear in a later backup. To remove all private app data, use Android’s Clear storage option. A WebView update link opens Android’s store or browser separately.
6. Retention and deletion
Local data stays on your device until you remove it. Deleting a plan removes its entries, notes and session history from the current database and requests deletion of its recordings. Removing individual content does not reset all practice/reward counters or guarantee erasure of every retained image or audio file. Restored or unreferenced files can remain locally. To remove all private app data, clear the app’s storage in Android Settings or uninstall it. The developer cannot remotely recover or erase this data.
The app disables Android cloud backup through its backup setting; some device manufacturers may still allow device-to-device transfer. Backups and recordings you exported remain at their chosen destination until you delete them separately, including any provider-managed copies. There is no Metronomaybe account to create or delete.
7. Optional website feedback
When the feedback form is available, your submission goes over HTTPS to private Cloudflare R2 storage for our support team to review. If attachments are enabled, you can send up to three images or videos totaling 30 MiB. We keep the files with their metadata. If the form is unavailable, you can reach us by email.
The feedback form asks for a category and your description. You may add an email address for a reply, device details, app version, screenshots or screen recordings. The selected website language, a receipt ID, submission time and your acknowledgement are saved with the report. Attachments may themselves contain personal information or metadata. Please remove anything you do not want included and obtain permission before including someone else’s information.
Form submissions, including any reply address and attachments, expire 90 days after upload. Cloudflare usually removes expired files within another 24 hours, but removal can take longer. To request earlier deletion, email privacy@neverplain.cc with your reference number.
You can email metronomaybe@neverplain.cc for help with Metronomaybe. If you send an email, we receive your email address, message and any attachments you include. We use them to handle your request and reply. Incoming mail is routed through Google. The 90-day rule applies to records submitted through the website form.
8. Website preferences and demonstrations
The demos run in your browser without accessing your microphone or practice records. The site remembers your language in local storage under neverplain-language. You can clear it in your browser’s site-data settings. We use no advertising or visitor-tracking scripts.
Cloudflare delivers the site and its videos. Its global network processes connection information such as IP addresses to deliver requests and prevent abuse. We do not include IP addresses or browser identifiers in feedback records.
