Flex Music Privacy Policy

Last updated: 26 August 2026

Back to Flex Music

Developer and contact

Flex Music is developed and operated by Elixir Consultancy Services Ltd, 7 Croftflat Drive, Fenay Bridge, Huddersfield, HD8 0FS, United Kingdom.

Privacy enquiries and data-deletion requests can be sent to support@elixircs.com.

Application identity

This policy applies to “Flex Music”, which may appear on Google Play as “Flex - Music Player” and on the Apple App Store as “Flex Music”.

Flex Music is an independent application and is not affiliated with or endorsed by Plex, Inc.

Overview

Flex Music connects to a Plex account and a user-selected Plex Media Server so that the user can browse, stream and manage their personal music library and playlists.

Elixir Consultancy Services Ltd does not operate a central Flex Music user-account service and does not receive or store the user’s personal music files.

Plex authentication and server data

  • Plex authentication takes place through Plex’s browser-based sign-in process.
  • Flex Music does not receive or see the user’s Plex password.
  • The Plex access token, selected server address and Plex account display name are stored locally on the user’s device.
  • The app communicates directly with Plex and the user-selected Plex Media Server to retrieve music-library metadata, stream audio, manage playlists, save ratings and perform requested library actions.
  • Library metadata may include track titles, artist names, album names, artwork, playlist contents, ratings and playback information.
  • Audio is streamed from the selected Plex Media Server and is not uploaded to Elixir Consultancy Services Ltd.
  • Offline downloads, cached artwork, lyrics, playback state and app preferences may be stored locally on the user’s device.
  • This locally stored information can be removed by clearing the app’s data, switching Plex servers where applicable, or uninstalling the app.

Plex’s own processing is governed by the Plex privacy policy.

Lyrics

When lyrics are not available from the selected Plex server, Flex Music may request lyrics from LRCLIB.

To perform the lookup, the app may send track metadata such as the track title, artist, album and duration to LRCLIB. Audio files are not sent to LRCLIB.

LRCLIB operates independently of Elixir Consultancy Services Ltd.

Purchases and subscriptions

Flex Music uses RevenueCat, together with the billing system of the store the app was installed from, to provide, validate and restore Flex Music Pro purchases and subscriptions. That is Google Play Billing on Android and Apple’s In-App Purchase system on iOS, iPadOS and watchOS.

Google Play or Apple processes the payment, according to the store the app was installed from. Flex Music and Elixir Consultancy Services Ltd do not receive or store full payment-card details.

RevenueCat may process:

  • Google Play or Apple App Store purchase history and transaction or receipt information;
  • purchased product identifiers;
  • subscription and entitlement status;
  • an anonymous or pseudonymous app user identifier; and
  • limited app, platform and device information required to operate and analyse the purchase service.

This information is used for app functionality, purchase validation, entitlement management, purchase restoration, customer support and purchase-related analytics. It is not used for advertising.

Advertising and tracking

  • Flex Music does not contain advertising.
  • Flex Music does not use an advertising identifier.
  • Flex Music does not sell personal information.
  • The current app does not use a general-purpose behavioural analytics or advertising SDK.
  • RevenueCat’s purchase-related analytics are used only to operate and understand purchases and entitlements.

Device permissions

  • Internet access: connects to Plex, the selected Plex Media Server, LRCLIB, Google Play or the Apple App Store, and RevenueCat.
  • Notifications: provides playback controls and playback information where permitted by the user.
  • Foreground media service and wake lock: support reliable background audio playback.

The current app does not request access to location, contacts, text messages, microphone or camera.

Data sharing

Data is disclosed only where necessary to provide the requested functionality, including to Plex, the user-selected Plex Media Server, LRCLIB, Google Play or the Apple App Store, and RevenueCat.

RevenueCat acts as a service provider for purchase validation and entitlement management. Flex Music does not share data with advertising networks or data brokers.

Data retention

  • On-device information remains until the user clears it, switches server where applicable, or uninstalls the app.
  • Purchase and entitlement records may be retained by Google Play, Apple and RevenueCat according to their policies and for legal, accounting, fraud-prevention and transaction-management purposes.
  • Support correspondence is retained only as long as reasonably necessary to resolve the request and meet legal obligations.
  • Elixir Consultancy Services Ltd deletes or anonymises data it controls when it is no longer required, subject to applicable legal-retention requirements.

Data deletion requests and user rights

Flex Music does not create a separate Flex Music account, so there is no Flex Music account to delete.

Users can request deletion of purchase-related data controlled through RevenueCat by emailing support@elixircs.com with the subject “Flex Music data deletion request”. The support team may request a Google Play order number, an Apple receipt or order ID, or other information necessary to identify the relevant anonymous purchase record. Users must not send payment-card information or their Plex password.

Under the UK GDPR, users may have rights to access, correct or delete their personal information, restrict its processing, object to its processing and receive a portable copy of it, where applicable.

Users may also complain to the UK Information Commissioner’s Office.

Security

Elixir Consultancy Services Ltd uses reasonable technical and organisational safeguards. Purchase-service communications use encryption in transit. Connections to Plex and a personal Plex Media Server also depend on Plex and the server configuration selected by the user.

International processing

Third-party providers may process information outside the United Kingdom. Appropriate safeguards are relied upon where required by applicable law.

Children

Flex Music is intended for users aged 18 and over and is not directed at children.

Changes to this policy

This policy may be updated when the app, its providers or legal requirements change. The revised “Last updated” date will be shown on this page.
