01Who is responsible
Bartosz Gosiewski, operating under the GØHER / GØ-404 brand, is the data controller for personal data handled in providing GØ-404 and responding to support and privacy requests. Contact: go404app@gmail.com.
This policy covers the GØ-404 app, this privacy website and correspondence you send to us about the app. You do not need a GØ-404 account. We do not operate a backend for your music library. Apple provides the App Store purchase and optional private iCloud services described below.
02Your projects, samples and local processing
GØ-404 processes the content you import, record or create: samples, projects, patterns and songs, pad assignments, recordings, CRATE entries, TURNTABLE slots and CUE points. Associated information can include names, local identifiers, dates, audio formats, edits, effect settings, preferences and integrity information.
Playback, waveform display, trimming, fades, Auto Chop, audio analysis, normalization, effects, exporting and resampling run on your device. These functions do not upload your audio to a developer server or cloud analysis service. Local autosave, editing history and recovery material help preserve your work; some features retain original audio so an edit can be reversed.
The app does not request your contacts, precise location, health records or advertising identifier. Your chosen content can nevertheless contain personal information, such as a recorded voice. Import or record content you are entitled to use.
03Microphone and USB SAMPLING
Recording through the microphone starts when you choose that function and allow the system audio-input permission. USB SAMPLING receives audio from a supported USB input that you connect and select. Recordings are handled locally; completed USB recordings are saved to CRATE. USB recording does not intentionally substitute the built-in microphone when a valid USB input is unavailable.
You can deny or revoke microphone access in iOS Settings. Functions requiring audio-input permission will then be unavailable. Revoking a permission does not erase recordings you already saved.
04GØ GRAB
GØ GRAB receives audio from other apps where iOS makes it available. On supported versions and devices it uses Apple ScreenCaptureKit. It can also use Apple ReplayKit and a system broadcast extension. You start capture using the relevant Apple system control, with system confirmation and capture indicators. Capture may continue while GØ-404 is in the background until it is stopped or interrupted.
Application audio is held in a local rolling buffer containing up to 30 seconds. GØ GRAB saves application audio only. The ScreenCaptureKit path requests application audio and excludes GØ-404’s own playback. The ReplayKit extension discards video frames and microphone audio. SAVE LAST writes the captured audio to your local CRATE. Recovery and journal material may remain after an interruption or an unfinished save; the 30-second buffer duration does not mean every related file is erased after 30 seconds.
GØ GRAB does not stream a broadcast to a developer server. Saved captures can be included in a backup you choose to make. Capture remains subject to iOS and the source app’s restrictions.
05TURNTABLE RECORDING
When you use TURNTABLE RECORDING, REC starts recording the processed scratch signal and STOP ends it. The recording is saved locally as a WAV file in CRATE. This function does not use the microphone to record scratching and does not include the separately playing background beat.
Your slot audio, CUE points and playback settings are stored locally. Saved scratch recordings are treated like other CRATE audio and can be imported, exported or included in GØ BACKUP at your request.
06Files, WAV import and export
The system Files picker gives the app access to files you select. GØ-404 creates local working copies. Selecting a file from iCloud Drive or another provider may cause that service to download it to your device.
WAV, stem and project exports use destinations you choose through system controls. If you select another app, a cloud service, email or a recipient, that destination receives the exported content under its own practices. GØ-404 does not automatically send your exports to us.
07Camera and selected photos
For an optional custom machine background, you can choose an image through the system photo or file picker, or take a picture with the camera. Camera access is requested for that action. The chosen image is resized and re-encoded locally.
The app does not scan your entire photo library or upload the selected background to a developer server. You can revoke camera access in iOS Settings. Saved app data may still be included in system device backups according to your settings.
08GØ BACKUP and private iCloud
If you choose GØ BACKUP, the selected project backup and the complete CRATE library snapshot included in that backup are uploaded to Apple’s CloudKit service. This includes CRATE audio not used by the selected project, names, identifiers, metadata and available trim history or recoverable originals. The backup can also include TURNTABLE slot audio, CUE points and playback settings. Backup manifests, integrity information and backup dates are stored with the backup.
The app uses the private CloudKit database associated with your Apple Account. Your backup is not published to a public database or sent to a GØ-404 backend. Private database records are not available to the developer through the CloudKit developer portal. Backup requires the relevant app entitlement, an available iCloud account and enough storage.
Ordinary local SAVE, LOAD and music editing do not initiate a GØ BACKUP upload. Opening the backup panel can retrieve the backup listing from iCloud. Restoring downloads the selected backup to your device.
Deleting local content or removing the app does not by itself delete an independent iCloud backup. The app does not automatically expire these cloud backups. Use Apple’s iCloud storage controls to manage the app’s cloud data; see Apple’s guidance for third-party app data. System iCloud or computer backups of your device are separate from GØ BACKUP and depend on your device settings.
09PRO and paid packs
Apple StoreKit handles the GØ-404 PRO subscription and one-time purchases such as paid drum and faceplate packs. The app reads verified purchase and entitlement information on your device to enable purchased features, restore access, handle expiry or revocation and display product information and localized prices.
We do not receive your payment card details or Apple Account password through the app. Receipts and transaction history are not uploaded to a developer-operated verification server. Apple handles billing and may provide developers with standard sales or financial reports. Apple’s handling of account and transaction information is described in Apple’s Privacy Policy. Purchases and subscriptions remain managed through Apple.
10Advertising, tracking and diagnostics
GØ-404 does not include advertising, cross-app advertising tracking, an advertising identifier, or a third-party analytics or crash-reporting SDK. We do not sell your personal data or share it with advertising networks or data brokers.
Operational diagnostics may record audio route and format information, engine status, timing, performance counters and error details locally. GØ-404 does not automatically upload these records to a developer analytics service. If you choose to send us diagnostic information, we handle it as part of your support request. Apple may separately process system diagnostics according to your settings and Apple’s policies.
11Support and recipients
If you email go404app@gmail.com, we receive your email address, message, any name you provide and any attachments you choose to send. We use them to answer your request and resolve related issues. Please send recordings or projects only when needed. The app does not automatically attach your library or send an email.
Our contact address uses Google’s Gmail service to handle correspondence. See Google’s Privacy Policy. Apple receives the information necessary to provide its purchase, iCloud and system services. File providers and recipients you choose receive the content needed for the import or export you request. We do not otherwise send your music library to these providers.
Opening a legal or support link can cause your browser or email app to contact the selected service. Those services handle their own connection and account information; GØ-404 does not add your projects or recordings to a legal-page request.
This policy page is hosted by GitHub Pages. GitHub logs visitor IP addresses for security. This page has no analytics scripts or contact form. See the GitHub General Privacy Statement.
12Retention and deletion
Local projects, CRATE audio, recordings and settings remain until you remove them through the relevant app or device controls. Original audio, Undo history and recovery material may remain while needed to support editing or recovery. Removing one pad assignment or trimming a sample is not necessarily deletion of every original copy.
Your exported files, copies sent to recipients, private iCloud backups and system device backups are independent of the local working copy. Manage those copies separately using the relevant service or device controls. We do not hold a developer-server copy of your private music library and cannot remotely retrieve or erase content held only on your device or in your private iCloud database.
Support correspondence is retained for the time needed to handle the request and related follow-up. When no longer needed, it is deleted or anonymized. Particular records may be retained longer where required by law or necessary to establish, exercise or defend legal claims; the applicable obligation or claim determines that retention period.
13Purposes and legal grounds
Where the GDPR applies, processing necessary to provide app functions you request, verify access or carry out your requested backup or restore is based on performance of the service contract, under Article 6(1)(b). This does not give us access to your private music content.
Handling general enquiries, investigating issues and protecting the app and related legal claims rely on our legitimate interests in providing effective support, maintaining the service and resolving disputes, under Article 6(1)(f). Processing needed to fulfil legal obligations, including responding to data-protection requests, relies on Article 6(1)(c). These purposes do not include advertising or cross-app profiling.
A system permission controls access to the microphone or camera. It is not blanket consent to unrelated processing. You can use functions that do not need a denied permission. Contact details are not required for ordinary music-making; providing an email address and relevant details is necessary if you want us to reply to a support request.
14Your data-protection rights
Subject to applicable conditions, you may request access, correction, erasure, restriction or portability of personal data we hold, and object to processing based on legitimate interests. If a use relies on your consent, you may withdraw it without affecting earlier lawful processing. Send requests to go404app@gmail.com.
We respond without undue delay, normally within one month. If the law permits an extension because of the complexity or number of requests, we will explain it within that initial period. We may request only the information reasonably needed to verify your identity and handle the request. You may complain to the competent data-protection authority, including the authority in your habitual residence or place of work in the EEA.
For content accessible only on your device or private iCloud account, we can explain the available controls but cannot access that content remotely. GØ-404 does not use your information for automated decisions that produce legal or similarly significant effects.
15International processing and security
Apple, Google and GitHub operate internationally, and information they handle may be processed outside your country, including outside the EEA. Apple describes its transfer safeguards, including standard contractual clauses, in its Privacy Policy. Google explains the adequacy frameworks and standard contractual clauses applicable to its services in its data-transfer information. These links provide information about the providers’ safeguards; you may also contact us for information about safeguards relevant to personal data we handle.
GØ-404 uses iOS app isolation, limited shared storage between the app and its capture extension, and integrity checks. Apple’s protections and your account settings govern cloud security. The app does not provide its own public audio-upload service. No storage or transfer method can be guaranteed absolutely secure.
16Changes and contact
We may update this policy when the app’s practices or applicable requirements change. Updated versions will be available on this page, with an effective date when published.
