Summary
Music Lab Plus (the "App") is developed by Chamela Aluthgedara (ChamelaLaboratory, "we", "us", "our"), based in Sri Lanka. The App is published on Google Play and, when available, on the Apple App Store. We are responsible for the personal data described in this policy and act as its data controller.
This policy applies to Music Lab Plus version 8.0 and later. Earlier versions (7.x and older) showed ads and used other third-party services, such as AdMob, AppLovin and Last.fm, under a previous policy. If you still use one of those versions, please update the App.
Contact: apps.support@ailivex.com.
This policy covers the App and this web page. Services run by others, such as Google Play, the App Store, Google Firebase, LRCLIB, YouTube, your email provider and the apps you share files with, have their own privacy policies.
This web page is served by Cloudflare, which processes standard connection data, such as your IP address and browser details, to deliver the page and protect the site. The page itself sets no cookies and loads no analytics or tracking scripts.
The App works on your device. The following is processed and stored only on your device. It is not sent to us or to anyone else, except as described in sections 5 and 6:
Playback, the equalizer and sound effects, visualizers, Studio editing, conversion and compression, Space Render, recommendations such as Daily Mixes, song radio and On this day, feature tips and reminders all run on your device.
The App reads the name of the connected audio output, for example your headphones or car, to show where music plays and to resume playback when it reconnects. If you turn on Sleep timer › Shake to add time (Android), the App uses the motion sensor only during the last minute of a running sleep timer. Neither is recorded or sent anywhere.
While music plays, the song's title, artist and artwork appear in your device's media controls, for example on the lock screen, in notifications, in home-screen widgets, on connected Bluetooth devices and in Android Auto.
Backups. A backup you make in Settings › Backup & restore is a file that goes only where you save or share it. You can protect it with a password: it is then encrypted on your device with AES-256-GCM, using a key derived from your password. We never receive your password and cannot recover a backup whose password is lost. Separately, on Android, only the App's settings (not your library data) can be included in your Google device backup and device-to-device transfer. On iOS, the App's data may be included in your iCloud or computer backups, depending on your device settings. Those backups belong to you, under your Google or Apple account, and we cannot access them.
Share cards. Share cards (for example streaks, Recap and Studio results) are images made on your device. They go only where you share or save them. By default they show the App's name and a store link; the link names only the kind of card, so the store can count installs from shared cards, and never identifies you or your device. You can remove the App's name in Settings › Privacy › Show app name on share cards. Your own audio and video exports are never marked.
Files you save outside the App or share with other apps are under your control.
The only personal data we receive directly is what you send us when you contact us, for example with Feedback in the App's menu or in Settings › About, which opens your email app.
Usage analytics and crash reports, described in section 5, are processed by Google Firebase for us. They are not linked to your name, email address or any account.
Usage analytics (Google Analytics for Firebase). Off until you turn it on: its switch starts off on the privacy page during setup, and you can change it at any time in Settings › Privacy › Usage analytics. While it is on, the App sends Google:
Analytics never includes song titles, artists, file names, paths, lyrics or the content of your files.
Crash reports (Firebase Crashlytics). Off until you turn them on: their switch starts off on the privacy page during setup, and you can change it at any time in Settings › Privacy › Crash reports. Before you turn them on, and whenever they are off, the App records and sends no error, and reports that the system kept while they were off are deleted without being sent. While they are on, when the App crashes or meets an error, the report contains:
To protect Premium, the App checks on your device whether it was modified or signed by someone else, runs with a debugger or with tools that change apps while they run, was installed from outside an app store, or runs on a rooted or jailbroken device or an emulator. The checks read only technical facts about the App and the device, such as which program libraries are loaded, never your files or anything about you. Only if crash reports are on and a check finds something, a report with short codes only (for example “debugger” or “root”) is sent. The checks never stop playback or the free features. If one finds that the App itself was tampered with, Premium bought in the store waits until the store confirms it again.
No advertising signals. The App removes the advertising ID permission on Android and does not collect the advertising identifier (IDFA) on iOS. Google's Consent Mode settings for ad storage, ad user data and ad personalisation are always set to "denied". The App does not track you across other companies' apps or websites.
Retention. Google keeps this data under Firebase's retention rules: crash reports are kept for up to 90 days, and analytics events for the period set in our Google Analytics data-retention setting, which Google limits to at most 14 months. Using Settings › Privacy › Delete app data resets the analytics identifier, so earlier data is no longer linked to your installation, and deletes crash reports not yet sent.
See Privacy and Security in Firebase and Google's Privacy Policy.
Online lyrics (LRCLIB). LRCLIB (lrclib.net) is an independent, free, community-run lyrics database that we do not operate. The App contacts it in two cases:
LRCLIB also receives standard connection data, including your IP address and an identification of the App (its name, version and store address). Lyrics found are kept only on your device. LRCLIB's own terms and privacy practices apply, and the service may not always be available.
Google Play and the Apple App Store. The stores handle downloads, payments, subscriptions, refunds, rating prompts and update information. They process your account and payment information as independent controllers, under Google's and Apple's privacy policies. To check your Premium status, the App asks the store which of the App's products your store account owns and receives purchase confirmations, such as the product, a purchase token or transaction ID and the subscription's renewal or expiry status. It checks them on your device and keeps only what it needs to unlock Premium. These confirmations are not sent to us.
Google Play billing diagnostics (Android). On Android, the App uses Google Play's billing library to check, sell and restore purchases. The App connects to Google Play at every start to check your Premium status, also before you make your choices on the privacy page, and from then on the library can send Google its own diagnostic information about how it works, with technical details of your device and of the App. Google handles it under Google's Privacy Policy. The App's Usage analytics and Crash reports switches don't control it. On iPhone and iPad, purchases use StoreKit, which is part of iOS.
App updates. After setup, when the App starts and when you return to it (at most every 30 minutes), it checks whether the store has a newer version and, if it has, asks you to install it. On Android, the App asks Google Play through Google Play's in-app update service, and Google Play shows and installs the update. On iPhone and iPad, the App asks Apple's App Store lookup service (itunes.apple.com) for its current version, sending only the App's identifier and your device's region, with standard connection data such as your IP address; the App Store installs the update. The App never downloads or installs code by itself. Google and Apple handle these requests under their own privacy policies.
Links and sharing. When you open a store page, this web page, a "Watch on YouTube" search for a song, an email or the system share sheet, the app or website you choose takes over, and its own policy applies from that point. A YouTube search contains the song's title and artist.
Under the EU and UK General Data Protection Regulation (GDPR) and similar laws, we rely on these legal bases:
The App does not ask for your location, contacts, camera, phone or SMS.
We do not sell or rent personal data, and we do not share it for targeted or cross-context behavioural advertising. Information is disclosed only:
Google Firebase, our email services and the other services above may process data in countries other than yours, including the United States. Where data protection law requires it, these transfers are protected by recognised safeguards, such as adequacy decisions or standard contractual clauses.
The App connects only over encrypted (HTTPS) connections. The online lyrics feature talks only to LRCLIB's fixed address and never fetches addresses from your files or from other apps. The App checks store purchase confirmations on your device and keeps your Premium status in the system's secure storage. Password-protected backups are encrypted with AES-256-GCM. Errors that the App's own code reports are cleaned of titles, file names and paths before they leave your device.
No method of transmission over the internet or of electronic storage is 100% secure. We work to protect the information we handle, but we cannot guarantee its absolute security.
The App is a general-audience music app. It is not directed to children under 13, and we do not knowingly collect personal data from children under 13, or under the minimum age for consent to online services where they live (up to 16 in some countries). If a child uses the App, a parent or guardian should decide whether to turn on usage analytics or crash reports. Purchases are made by the holder of the store account, and the stores offer parental controls for them. If you believe a child has sent us personal data, email us and we will delete it.
Information on your device stays in the App's storage until you delete it, use Delete app data, clear the App's data or uninstall the App. Support messages are kept as described in section 4. Firebase data is kept as described in section 5.
You control the information on your device. You can:
Depending on where you live, you may have the right to access, correct, delete or export your personal data, to restrict or object to its use, to withdraw consent, and to complain to a data protection authority. These rights come from:
To use them, email us at apps.support@ailivex.com. We will answer within 30 days, or sooner if the law requires. Analytics and crash data are not linked to your name or email address, so we usually cannot look them up for you; the switches and Delete app data above are the way to stop and reset them. For data held by Google, Apple or LRCLIB as independent providers, contact them directly. To cancel a subscription, use your Google Play or App Store account settings.
We do not track you across other companies' apps or websites, and we do not sell or share personal data for advertising, so there is nothing to change when your browser or device sends these signals.
We may update this policy. When we do, we will publish the new version on this page with a new effective date. Where the law requires, we will also give you additional notice or ask for your consent again.

Please read these terms carefully. They are the licence agreement for the App and include the subscription terms (section 11), a hearing-safety notice (section 9), a disclaimer of warranties, a limitation of our liability and rules for resolving disputes (sections 17 to 21).
These Terms of Use ("Terms") are a legal agreement between you and Chamela Aluthgedara (ChamelaLaboratory, "we", "us", "our") about the Music Lab Plus app (the "App"). They are the App's end-user licence agreement. By downloading, installing or using the App, you agree to these Terms. Our Privacy Policy explains how we handle information; please read it too. If you do not agree, do not use the App.
You may use the App if you can form a binding contract where you live. If you are a minor, you may use the App only with the involvement and consent of a parent or guardian, who accepts these Terms for you and is responsible for your use of the App and for any purchases. The App is not directed to children under 13.
Subject to these Terms, we give you a personal, limited, non-exclusive, non-transferable, revocable licence to install and use the App on devices you own or control, for your own lawful purposes, and under the rules of the store you got it from. We reserve all rights not expressly granted.
If you got the App from Google Play, the Google Play Terms of Service also apply. Google is not a party to these Terms and is not responsible for the App.
If you got the App from the Apple App Store, Apple's Licensed Application End User License Agreement (the "Standard EULA") also applies, and it prevails where it conflicts with these Terms for your use on Apple devices. In addition:
The App, including its software, design, text, graphics, sounds and trademarks, belongs to us or our licensors and is protected by intellectual property laws. The App includes open-source software and fonts under their own licences, among them FFmpeg through FFmpegKit (LGPL 3.0), Flutter and many Dart packages (BSD, MIT and Apache 2.0 licences), the Plus Jakarta Sans font (SIL Open Font License) and Material Icons. Those licences govern those components; see Settings › About › Open source licenses in the App. Nothing in these Terms limits the rights an open-source licence gives you, including any right to modify or replace a library under the LGPL and to reverse-engineer the App only as far as needed to debug such changes.
You keep all rights you have in your music, recordings, lyrics, images and other files, and in what you create with the App ("Your Content"). Your Content is processed on your device. We do not receive it and claim no rights to it.
You are solely responsible for Your Content and for having every right, licence and permission needed to play, edit, cut, convert, compress, merge, remix, record, share or publish it, or to set it as a ringtone. The App does not give you any rights to music or other works that belong to someone else. Editing, converting or sharing a song or video that belongs to someone else, or publishing the result, may need the rights holder's permission. You must not use the App to get around any copy protection or digital rights management.
Lyrics, whether from LRCLIB, your files or any other source, may be protected by copyright. Lyrics from LRCLIB are shown to you for your personal use only, and we do not check them for accuracy or rights.
Some features change or remove files on your device when you confirm them, for example editing a song's details or cover, deleting songs, saving over an existing file, replacing an original with a compressed copy, setting a ringtone or restoring a backup over your current data. Make your own backups of anything that matters to you before you use these features. Deleting items, using Delete app data or uninstalling the App deletes the data it held, and a backup whose password is lost cannot be recovered. To the maximum extent permitted by applicable law, we are not responsible for the loss of, or damage to, any file, recording or data.
Listening at high volume for long periods can permanently damage your hearing. The equalizer, bass boost, preamp, loudness and other effects, and 3D or 8D audio, can make sound louder or change how loud it seems. Start at a low volume, raise it slowly, take breaks and follow your device's volume warnings. Strong settings can also damage speakers or headphones. Healthy-listening features, such as ear breaks and the bedtime wind-down, are reminders only and are not medical advice; the App is not a medical or hearing-protection device.
Pay attention to your surroundings. Do not set up or operate the App in a way that distracts you while driving, cycling or doing anything that needs your full attention, and follow the traffic laws where you are, including when you use Android Auto. You use the App at your own risk.
You agree not to use the App to:
If you bought Premium as a one-time purchase in version 7.x or earlier, you keep Premium forever, at no extra cost, and never need a subscription for it. It is restored with the same Google Play account, also on a new device (Settings › Subscription › Restore purchases). If Premium was active in version 7.x on your device when you updated, the App keeps it on that device. One-time purchases are not sold any more. Version 8 has no ads, and the features that needed an ad in version 7.x (Space Render export and the counter-clockwise orbit) are free.
Some features rely on services run by others: Google Play and the Apple App Store for purchases, Google Firebase for analytics and crash reports, LRCLIB for online lyrics, YouTube for song searches you open, Android Auto, your device's media controls and the apps you share files with. Their own terms apply. We do not control these services and, to the maximum extent permitted by applicable law, are not responsible for their availability, content, accuracy or practices. LRCLIB in particular is a free community service that may change, limit or stop at any time.
We may update, change, suspend or discontinue the App or any feature at any time, and some updates may be required to keep using it. We do not guarantee that the App will always be available, error-free or secure, that it will play, edit or convert every file, or that it is compatible with every device, operating system, car or accessory.
If you send us ideas or suggestions, we may use them freely, without any obligation or payment to you.
You may stop using the App at any time by uninstalling it. We may suspend or end your licence if you breach these Terms. When the licence ends, you must stop using the App. Sections 6 to 10, 13 and 17 to 24 survive termination.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE APP AND ALL ITS FEATURES, CONTENT AND OUTPUT ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITH ALL FAULTS AND WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED OR STATUTORY. THIS INCLUDES ANY WARRANTIES OF MERCHANTABILITY, SATISFACTORY QUALITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, QUIET ENJOYMENT, NON-INFRINGEMENT AND UNINTERRUPTED OR ERROR-FREE OPERATION, AND ANY WARRANTY THAT EDITS, CONVERSIONS OR EXPORTS WILL BE LOSSLESS OR THAT LYRICS WILL BE CORRECT. YOU USE THE APP AT YOUR OWN RISK.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE ARE NOT LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, FILES, CONTENT, PROFITS, REVENUE, GOODWILL OR BUSINESS OPPORTUNITY, ARISING FROM OR RELATED TO THE APP, THIRD-PARTY SERVICES OR THESE TERMS, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE) OR OTHERWISE, EVEN IF WE WERE TOLD OF THE POSSIBILITY.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, OUR TOTAL LIABILITY FOR ALL CLAIMS RELATED TO THE APP OR THESE TERMS IS LIMITED TO THE GREATER OF (A) THE AMOUNT YOU PAID FOR PREMIUM IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM AND (B) USD 10.
Nothing in these Terms excludes or limits any right or remedy that you have under mandatory law and that cannot be excluded or limited, or any liability that cannot be excluded or limited by law. This includes liability for death or personal injury caused by negligence and liability for fraud, and, where they apply, your statutory rights as a consumer in the European Union, the United Kingdom, Australia (including the consumer guarantees under the Australian Consumer Law), New Zealand and elsewhere. Where the law allows our liability for breach of such a right to be limited, it is limited, to the maximum extent permitted by applicable law, to supplying the App again or refunding what you paid. If you live in the EU or the UK, we are also liable as the law requires for losses that are a foreseeable result of our breach of these Terms or our failure to use reasonable care and skill.
To the maximum extent permitted by applicable law, you agree to indemnify and hold us harmless from any claims, damages, losses, liabilities and expenses, including reasonable legal fees, arising from Your Content, your misuse of the App, or your breach of these Terms, of the law or of anyone else's rights.
These Terms are governed by the laws of Sri Lanka, without regard to its conflict-of-law rules. Before bringing any claim, please email us so we can try to resolve the issue informally within 30 days.
The courts of Colombo, Sri Lanka, have exclusive jurisdiction over any dispute about the App or these Terms. If you are a consumer, however, you may also bring claims in the courts where you live, and you keep the protection of the mandatory laws of your country.
To the maximum extent permitted by applicable law, disputes are resolved individually and not as part of a class or representative action, and any claim must be brought within one year after it arises.
You confirm that you are not located in a country subject to comprehensive embargoes and that you are not on any government list of prohibited or restricted parties. You agree to use the App in compliance with all applicable export and sanctions laws.
We may update these Terms. The new version takes effect when it is published on this page with a new effective date. Where the law requires, we will also give you additional notice, and we may ask you to accept the updated Terms in the App. If you keep using the App after the change, you accept the updated Terms. Changes do not affect purchases you made before them, except as the store's rules or the law allow.
