Privacy Policy

Who we are

Equalizer ("the App") is an application for iPhone, iPad and Mac developed and published by the developer of Equalizer ("the Developer", "we", "us"). This policy explains what information the App does — and does not — handle when you use it, on every platform. Where the iPhone/iPad and Mac versions differ, this policy says so.

Data we collect

The App collects anonymous usage statistics through Google Firebase Analytics so we can understand which features are used and improve the App. This includes:

• Usage events — for example which screens are opened and which features are used
• General device information — device model, operating-system version (iOS, iPadOS or macOS), language and approximate location derived from your IP address (country or city level; the App never uses GPS)
• A randomly generated app-instance identifier used to count sessions. This is not your name, email or phone number, and it is not your device's advertising identifier — the analytics component has no access to that. Advertising is handled separately and described under Advertising below.

This data is not linked to your identity and is not used to track you across other companies' apps or websites. Google processes it on our behalf as described in the Firebase privacy documentation.

The App does not have:

• User accounts or sign-in of any kind
• Access to your contacts, precise (GPS) location, camera, microphone, or photos
• Any collection of your music, imported files, or listening content — audio never leaves your device

Advertising

Mac: the Mac version of the App contains no advertising SDK, never requests ads, never accesses an advertising identifier and never asks for tracking permission. Everything in this section applies to iPhone and iPad only.

On iPhone and iPad, the free version of the App is supported by advertising delivered through Google AdMob. Ads appear only at these points: once shortly after you open the App, and occasionally when you close the full-screen player, close the full-screen visualiser, finish the hearing test, or finish importing files. They are frequency-capped, never appear more than a few times per session, and are never shown to a brand-new user on their first session. Ads never interrupt or silence your music — playback continues underneath.

A Premium subscription removes all advertising. Premium subscribers make no ad requests at all.

To serve ads, Google may process your device's advertising identifier (IDFA), general device and network information, and coarse location derived from your IP address. Google may use this to show you personalised ads, subject to your choices below. This handling is described in Google's business privacy notice and the AdMob partner list.

Your choices:

• App Tracking Transparency — iOS asks your permission before the App may use the advertising identifier. If you decline, ads still appear but are non-personalised. You can change this at any time in iOS Settings → Privacy & Security → Tracking.
• EEA, UK and Switzerland — a consent form appears before any ad is requested, as required by the GDPR and Google's EU user consent policy. You can reopen it at any time from Settings → Privacy choices inside the App.
• Remove ads entirely — subscribe to Premium.

Information that stays on your device

To function, the App stores some information locally on your device only. It is never uploaded anywhere and is deleted when you delete the App:

• Audio settings — your equalizer curves, custom presets, bass/boost levels, effect settings and per-device preset assignments
• Preferences — theme choice, default preset, repeat mode and similar options
• Imported audio files — copies of the files you choose to import, kept in the App's private storage
• Playback history — a short local list of recently played tracks, used only to show the "Recently Played" row

Music library and file access

iPhone and iPad: with your permission, the App reads your device's music library so it can list and play your songs. This access is used solely for playback and equalization on your device. The App never uploads, indexes, or transmits your library or listening habits. You can revoke this permission at any time in iOS Settings, and the App continues to work with imported files.

Mac: the App does not access your Music library. It runs in Apple's App Sandbox and can read only the audio files you choose yourself — through the Import button or by dragging them onto the App. Those files are copied into the App's private container on your Mac and never leave it.

When you contact support

If you tap Contact support in the App, it opens an email draft in your own mail app, pre-filled with details that help us answer quickly: the App version and build, whether you are using the iPhone/iPad or Mac version, your device model (for example "iPhone16,1" or "Mac14,2"), operating-system version, subscription status (free or Premium) and preferred language. Nothing is sent until you press Send, and you can edit or delete any of it first. We use what you send only to answer your request.

Purchases

Premium subscriptions are processed entirely by Apple through the App Store's StoreKit system, and one subscription covers the App on iPhone, iPad and Mac when you use the same Apple ID. We never see or store your name, payment details, or billing information. Apple provides the App only with an anonymous confirmation that a subscription is active. Apple's handling of your purchase data is governed by Apple's Privacy Policy.

Third parties and how long data is kept

Google is the only third party that receives any data from the App — Firebase Analytics on every platform, and AdMob advertising on iPhone and iPad only. We do not sell, rent or share data with anyone else, and there are no other analytics, attribution or advertising SDKs in the App. Google processes this data under its own published privacy commitments, which we require to provide protection of your data equal to or stronger than this policy: see Google's business privacy notice and the Firebase privacy documentation.

Retention:

• On your device — presets, settings, imported files and playback history are kept until you change or remove them, and are deleted entirely when you delete the App.
• Anonymous analytics — Google deletes individual event records after 2 months. The user-level record attached to the anonymous app-instance identifier is deleted 14 months after your last use of the App, and that period restarts each time you use it again, so it is removed once you stop. Neither record is linked to your identity. Aggregated statistics (such as how many people used a feature) contain no individual data and are kept indefinitely.
• Advertising data — retained and deleted by Google under its own retention policy for AdMob. You can break the link at any time by resetting or disabling your advertising identifier in iOS Settings. (Not applicable on Mac, which shows no ads.)
• Purchases — held by Apple, not by us. We never receive or store payment records.

Because we hold nothing that identifies you, deleting the App removes everything within our reach; anything remaining sits with Google or Apple under the policies linked above.

This website

This website is a set of static pages hosted on Google Firebase Hosting. It uses no cookies and runs no analytics scripts. As with virtually all web hosting, Google's infrastructure may temporarily log standard technical data (such as IP addresses) for security and operational purposes, as described in Google's Firebase privacy documentation. We do not access or use such logs to identify anyone.

Children's privacy

The App is rated 4+ and collects no personal information from anyone, including children. The anonymous usage statistics described above are not linked to any individual and contain no personal data. Advertising served in the free version is configured for a general audience and is not directed at children.

Your rights

We hold no personal data that identifies you, so there is nothing for us to disclose, export, correct, or delete on your behalf. Your settings and files live on your device; deleting the App (on Mac, moving it to the Trash and removing its container) removes them and resets the anonymous analytics identifier. On iPhone and iPad you can reset or disable the advertising identifier at any time in Settings → Privacy & Security → Tracking. For purchase records, contact Apple through your App Store account. If you have any privacy question or request, email us and we will help.

Changes to this policy

If the App's data practices ever change — for example, if a future version adds an online feature — this policy will be updated before that version ships, with the "last updated" date revised above. Material changes will also be noted in the App's update notes.
