The rules, in plain English.

01 The licence we grant you

Subject to these terms, Dusty Enterprise SRL (registered in Bucharest, Romania) grants you a personal, revocable, non-transferable, non-exclusive licence to install and use Serento on iOS, iPadOS and macOS devices you own or control. The licence is for personal, non-commercial purposes. You're not buying the app - you're buying the right to run it under these terms.

02 Trial, subscription, and lifetime purchase

Serento ships with a 14-day free trial that starts when you first launch the app on an Apple ID that has never used the trial before. After 14 days the trial expires and access to the app requires an active subscription or a one-time lifetime purchase. All billing is handled by Apple via the App Store.

• Annual subscription. Auto-renews for the published yearly price unless cancelled at least 24 hours before the renewal date. Manage and cancel on iOS and iPadOS in Settings → [your name] → Subscriptions, and on macOS in App Store → [your name] → Account Settings.
• Lifetime purchase. A one-time payment that unlocks the app for the lifetime of the product. No recurring billing. Tied to the Apple ID that made the purchase; Apple's Family Sharing rules determine whether it carries to family members.
• Free trial - anti-abuse. To prevent the same Apple ID from cycling through repeated 14-day trials, the date your trial started is kept on our server, against a one-way key derived from your iCloud account identifier. iCloud must be enabled in your device settings for the trial to start. The key cannot be turned back into an Apple ID and the record answers a single question: has this account already used its trial? The trial belongs to the Apple ID, not to the device: a different Apple ID signing in on the same hardware is a different person and gets its own fourteen days. Serento checks in with the trial service from time to time; if it cannot reach us at all, the app keeps working for up to fourteen days from the first such launch, and then asks you to connect once before continuing.
• Pricing. Current prices are shown inside the app on the subscription screen. Apple may convert prices to your local currency and apply local taxes. We may change prices for future renewals with reasonable notice; existing subscriptions renew at the price displayed at the time of the most recent billing event unless we explicitly notified you otherwise.

03 Refunds

Refunds for App Store purchases - including Serento subscriptions and the lifetime purchase - are processed by Apple, not by Dusty Enterprise SRL. To request a refund, use Apple's "Report a Problem" flow at reportaproblem.apple.com. EU consumers retain their statutory 14-day right of withdrawal under Directive 2011/83/EU; exercise it via the same Apple flow.

04 What you may not do

These restrictions apply to your use of the app:

• Reverse engineer, decompile, or disassemble. Except where this is expressly permitted by law (notably under EU Directive 2009/24/EC for interoperability purposes you cannot otherwise achieve).
• Redistribute the app. Don't sell, sublicense, rent, lease, host, or otherwise transfer your copy of Serento to anyone else. The licence is yours, not yours to give away.
• Circumvent technical measures. Don't bypass any DRM, geo-restriction, or access control on streams you play through Serento. Don't attempt to defeat the trial / subscription gating.
• Use the app for unlawful content. Don't use Serento to stream, broadcast, or facilitate access to copyrighted material you don't have the rights to. You're the one connecting the app to your servers and streams; what flows through is your responsibility.
• Misuse the diagnostic-log channel. The "Send Logs to Developer" button is for genuine bug reports. Don't use it as an alternative channel for marketing, harassment, or anything else.

05 Your music and your servers

Serento doesn't host or distribute music. It's a control application: it browses your UPnP servers (MinimServer, Plex, Twonky, Asset UPnP, JRiver Media Center, Kodi UPnP, and similar) and tells your renderer what to play. The audio bytes flow from your server directly to your renderer; we never touch them. You're responsible for: owning or being licensed to access the content on your servers; complying with the licence terms of any internet radio station you tune to; respecting copyright and broadcasting rights in your jurisdiction.

06 Internet radio

A radio preset in Serento is just metadata - name, codec hint, and stream URL. When you press Play, your device connects to the broadcaster's URL directly. We have no relationship with the broadcaster and no visibility into the stream content. Broadcasters change, redirect, paywall, or shut down streams at their own discretion; we're not responsible for stream availability or audio quality.

07 Compatibility & service availability

Serento is built and tested against a specific set of UPnP servers and audiophile renderers. It works with most spec-compliant UPnP / OpenHome devices, but the UPnP-AV / OpenHome ecosystems are decades old and full of vendor-specific quirks. We can't guarantee compatibility with every server or renderer ever made. Concretely:

• Tested servers. MinimServer, Asset UPnP, Plex.
• Tested renderers. Rockna, Linn, Lumin, Esoteric, Technics, iFi, WiiM, Eversolo.
• Beyond that. Your mileage may vary. Some devices have firmware quirks that no third-party control application can fully work around - those will manifest as the same behaviour you'd see with any other control application app.

08 Network access required

Serento needs Local Network permission to discover and control UPnP servers and renderers on your Wi-Fi network. The first time you launch the app on a new device, the system will prompt you for it. You can revoke it at any time: on iOS and iPadOS in Settings → Serento → Local Network, and on macOS in System Settings → Privacy & Security → Local Network. If you do, server browsing and remote-renderer playback stop working, but local playback to the built-in output of your iPhone, iPad or Mac continues to function.

09 iCloud requirement

The 14-day free trial requires an iCloud account signed in on the device, because the iCloud account is the only thing that identifies a trial. An active subscription or a lifetime purchase does NOT require it: StoreKit verifies the purchase on the device against Apple's own signature, so a paid copy of Serento keeps working with iCloud switched off. If you have neither purchased Serento nor hold a valid trial, a confirmed iCloud account is required to use Serento at all: without one, the app opens on a screen asking you to sign in rather than on your library. That is deliberate. If you have purchased, or your trial is running, signing out of iCloud only stops sync of your favourites, playlists, tags, and bookmarks - see the Privacy Policy for the full data inventory. None of the content in your iCloud container reaches our servers. At account level the only thing we keep is the one-way key described above; for the pseudonymous telemetry the app also sends, see Section 18.

10 Updates and beta features

We release updates through the App Store at our discretion. Updates may add, change, or remove features. Some features in the app may be labelled as beta or experimental - those are exploratory work that may change shape, behaviour, or disappear without notice. Beta features are offered "as is" with no implicit promise that they'll be retained in the final product.

11 Warranty disclaimer

Serento is provided "as is" and "as available". To the maximum extent permitted by applicable law, Dusty Enterprise SRL disclaims all warranties, express or implied, including but not limited to fitness for a particular purpose, merchantability, and non-infringement. We don't warrant that the app will be uninterrupted, error-free, free of security vulnerabilities, compatible with every device, or that audio playback will be bit-perfect on every server / renderer / DAC combination. This disclaimer does not affect statutory rights you cannot waive under your local consumer-protection law - see Section 14.

12 Limitation of liability

To the maximum extent permitted by law, Dusty Enterprise SRL's total liability arising out of or in connection with these terms or your use of Serento - whether in contract, tort, statute, or otherwise - is limited to the amount you paid for the app in the 12 months preceding the event giving rise to the claim. We are not liable for any indirect, incidental, consequential, special, punitive, or exemplary damages, including but not limited to lost profits, lost data, or loss of goodwill. Nothing in these terms limits liability for death, personal injury caused by negligence, fraud, fraudulent misrepresentation, or any other liability that cannot be limited or excluded under applicable law.

13 Third-party services Serento depends on

Serento's normal operation involves several third parties. Each has its own terms, which we are not party to and have no control over:

• Apple Inc. App Store distribution, iCloud / CloudKit sync, StoreKit billing, system frameworks. Your separate agreement with Apple governs these.
• Plex Inc. Only if you connect a Plex Media Server. Your separate agreement with Plex governs your Plex account and servers.
• Your UPnP server vendor. MinimServer, Asset UPnP, Twonky, JRiver, Kodi, etc. - each has its own licence and terms.
• Internet radio broadcasters. When you play a station, you connect to the broadcaster directly. Their terms govern that connection.

14 Consumer rights (EU)

If you acquired Serento from the App Store as a consumer resident in the European Union, the United Kingdom, or another jurisdiction with mandatory consumer-protection rules, your statutory rights under that law remain in full force. Nothing in these terms overrides them. In particular: the EU 14-day right of withdrawal for digital content (Directive 2011/83/EU), the right to a conforming product under the Sale of Goods Directive (EU 2019/771), and any equivalent rights in your jurisdiction. Refunds are processed by Apple - see Section 03.

15 Termination

These terms remain in effect until terminated. You can terminate at any time by deleting the app from your device(s). We may terminate or suspend your licence if you materially breach these terms. On termination, your right to use Serento ends; uninstalling the app removes the local data the app stored on your device (see the Privacy Policy for the inventory). Sections 11, 12, 13, and 16 survive termination.

16 Governing law and dispute resolution

These terms are governed by the laws of Romania, excluding its conflict-of-laws rules. Disputes that cannot be resolved informally fall under the exclusive jurisdiction of the competent courts in Bucharest, Romania - without prejudice to any mandatory consumer-jurisdiction rules in your country of residence (within the EU, consumers can bring proceedings in the courts of their home country under Regulation (EU) 1215/2012).

17 Apple-required terms

The following provisions are required by Apple's App Store distribution model, in addition to (and not in place of) anything else in these terms:

• Apple is not a party. These terms are between you and Dusty Enterprise SRL. Apple is not a party to them and has no obligations relating to the app under them.
• Standard Apple EULA applies. The Apple Media Services Terms and the Licensed Application End User Licence Agreement (apple.com/legal/internet-services/itunes/dev/stdeula) apply alongside these terms; in case of conflict, the more user-protective rule prevails for EU consumers.
• Maintenance and support. Apple has no obligation to provide any maintenance or support services for Serento.
• Warranty. In the event of any failure of Serento to conform to any applicable warranty, you may notify Apple, and Apple will refund the App Store purchase price (if any). To the maximum extent permitted by law, Apple has no other warranty obligation.
• Claims. Any product-liability, conformity-to-law, or consumer-protection claims relating to the app are the responsibility of Dusty Enterprise SRL, not Apple.
• Third-party beneficiary. Apple and Apple's subsidiaries are third-party beneficiaries of these terms and may enforce them against you.

18 Privacy and pseudonymous telemetry

Use of Serento is also governed by the Serento Privacy Policy. It describes what data the app processes, what stays on your device, what (if anything) syncs via Apple iCloud, and what your rights are under the GDPR.

As a condition of using Serento, you agree that the app collects and sends us privacy-preserving telemetry - a one-way (irreversible) hash of your iCloud account identifier (we never receive the identifier itself), which is the key both your telemetry and your subscription are stored under; a device identifier the app generates for itself so your devices can be told apart; coarse device facts and app-usage durations; the capabilities of the renderers you use; and library-composition counts/percentages, including how complete your music metadata is - all itemised in Section 02a of the Privacy Policy. It contains no name, email or Apple ID, and the key is one-way, so it does not reveal who you are or the contents of your library. It is never sold, and raw reports are deleted after 13 months. Because it is integral to maintaining and improving the product, there is no in-app opt-out; if you do not agree to it, your remedy is to not use the app.

19 Changes

We may revise these terms from time to time. Material changes will be announced in-app and reflected on this page with an updated effective date. If you continue using Serento after the new terms take effect, you accept them; if you don't accept them, your remedy is to stop using the app and (if you wish) request a refund via Apple as outlined in Section 03.
