Privacy Policy

Effective Date: September 6, 2026 · Last Updated: September 6, 2026

This Privacy Policy explains how SoundBud, developed by Alp Kurbetci of Alpino Tech, collects, uses, and protects your information when you use the app.

The data controller responsible for the personal data described in this policy is:

  • Controller: Alpino Tech (Alp Kurbetci)
  • Postal address: Mimar Sinan Mahallesi, Yeşilkayalar Caddesi, Çekmeköy/İstanbul, Türkiye

You can contact us about this policy or about your data at: info@alpaconaudio.com

1. Information We Collect

1.1 Personal Data

You can create an account with an email address and password, with Sign in with Google, or with Sign in with Apple. All three are handled by Firebase Authentication, and in each case we collect your:

  • Email address

We may also collect user-submitted feedback, including suggestions and support messages, which may be associated with your email address.

1.2 Usage Data

We use Firebase Analytics to collect pseudonymous usage data. It is linked to an identifier that is your account ID when you are signed in, and a random install ID when you are not. Examples of what we collect:

  • App screen views
  • Button taps
  • Session duration
  • Device type and OS version
  • Feature events, including paywall_shown, paywall_purchase_success, trial_start, retention_milestone, song_recognition and enhance_exported

We also set a small number of user properties on that identifier, so we can see how different groups of musicians use the app:

  • is_premium (whether your subscription is active)
  • persona (the profile you chose during onboarding)
  • app_lang (the display language of the app)
  • device_region (the region set on your device)
  • install_week and install_days (when you installed the app and how long ago)
  • activation (whether you have completed your first analysis)
  • lifetime_analyses (how many analyses you have run)
  • has_library (whether you have saved anything to your library)

The content of your audio, the titles of your songs and the text of your feedback never reach Analytics.

1.3 Audio Data

If you record or upload audio, we temporarily process your recording to extract audio features like BPM, key, chords, spectral information, and more. Your audio is written to the temporary working space of the analysis function while it runs and deleted when the analysis finishes. It is never written to any database or object storage, and no copy is retained. We do not use your audio for any other purpose or share it.

1.4 Ads

We use Google AdMob to serve ads. These may be personalized based on your device’s ad settings. In accordance with Apple’s App Tracking Transparency (ATT) framework, iOS users are asked for consent before allowing personalized ad tracking. If permission is denied, only non-personalized ads will be shown. You can opt out of personalized ads through your device or via the app’s Settings menu.

We also send Google a small set of topic keywords based on the persona you chose during onboarding (for example “music” or “podcast”) so the ads suit the app. These describe the topic, not you, and are sent whether or not you allowed tracking.

1.5 AI-Powered Analysis (OpenAI)

To generate the Theory / Solo Guide / Reharmonize / Explain insights, we send anonymized music metadata extracted from your audio (BPM, detected chords, genre, instruments, and, if identified, song title and artist) to OpenAI’s GPT models. We never send raw audio to OpenAI. OpenAI processes the request according to its own privacy policy.

We also use OpenAI when you open the AI tips or the Voice-Over Auto controls in Polish. In that case we send numeric measurements of your audio (loudness, true peak, dynamic range, spectral balance), the detected genre, and whether your account is free or premium. Your audio file itself is never sent; all Polish audio processing happens on your device.

1.6 Song Recognition (AudD)

When you record or upload audio, a short base64-encoded portion may be sent to AudD’s music recognition API to identify the song. AudD processes the audio in real time; per its privacy policy it does not retain the audio. Recognition is a premium feature; on the free tier no audio is sent to AudD at all.

1.7 Photo Library and Camera

SoundBud asks for access to your photo library so you can pick a video to work on. When you choose a video for Polish or for Decode, the app opens it on your device and separates the audio track from it. The video itself never leaves your device: we do not upload it, and we never see the rest of your photo library. Only the audio taken from the video is analyzed, following the same path described above for recordings.

SoundBud may also ask for camera access. The app itself never opens the camera and never records or stores images or video; the permission exists only because interactive ad formats served by our advertising partner can request it. If you decline these permissions, everything else in the app keeps working.

2. How We Use Your Information

  • Authenticate and personalize your experience
  • Improve app performance through analytics
  • Serve relevant ads (AdMob)
  • Process your audio inputs for music/sound feature extraction
  • Review feedback and suggestions to improve app features and support

3. Third-Party Services

We use the following trusted third parties:

  • Firebase by Google (Authentication, Analytics, and Cloud Firestore, where your feedback and support messages are stored together with your email address)
  • Sign in with Google and Sign in with Apple (optional ways to create your account and sign in, handled through Firebase Authentication)
  • Google AdMob (Advertisements)
  • Google User Messaging Platform (ad consent management for users in the European Union and the United Kingdom)
  • Apple AdServices (Apple Search Ads attribution token, used to attribute installs to ad campaigns)
  • Amazon Web Services (audio analysis via AWS Lambda in the EU, Stockholm region)
  • OpenAI GPT models (for analysis insights, anonymized metadata only)
  • AudD (song recognition, premium only)
  • Sentry (crash reporting and stability monitoring, EU region)
  • RevenueCat (in-app subscription management)

These services may store and process your data under their own privacy policies.

The requests to OpenAI, AudD and AWS Lambda are made directly from your device rather than through our servers, so each of these services also sees your device IP address, which they may use for security and abuse prevention under their own policies.

Sentry (sentry.io, EU region)

We use Sentry for crash reporting and stability monitoring. When the app encounters an error or crashes, Sentry collects: stack trace, device model, iOS version, app version, and a pseudonymous identifier (your account ID, or a random install ID if you are not signed in). We do not send your email address, your audio, or AI prompt content to Sentry. Sentry is configured not to store IP addresses. Data is stored in the European Union (Frankfurt) with a 90-day retention period.

Sentry’s privacy policy: https://sentry.io/privacy/

RevenueCat (revenuecat.com)

We use RevenueCat to manage in-app subscription purchases and entitlement validation. When you purchase or restore a subscription, RevenueCat receives your account identifier (the same one used for your SoundBud account), the App Store transaction ID, your subscription status, your device region, the Apple Search Ads attribution token, and device identifiers used for attribution (IDFV always; IDFA only if you allowed tracking; your IP address). It never receives your name, email address, or payment card details, which stay with Apple. RevenueCat acts as a data processor on our behalf.

RevenueCat’s privacy policy: https://www.revenuecat.com/privacy

4. Data Security

We use encryption, secure storage, and access controls to protect your data. However, no system is 100% secure, and you use the app at your own risk.

5. User Rights

Depending on your location, you may have rights to:

  • Access or delete your data
  • Withdraw consent
  • Object to analytics processing
  • Opt out of personalized ads

Deleting your account also deletes the feedback and support messages linked to your email address. If a message cannot be deleted, we strip the email address from the record, so it can no longer be traced back to you.

You can manage ad personalization in the app’s Settings menu or in your device settings. Reinstalling the app resets the random install identifier that pseudonymous analytics data is linked to. For anything else, including access, deletion and objection requests, write to us at: info@alpaconaudio.com

You also have the right to complain to a data protection authority. In the European Economic Area and the United Kingdom you can lodge a complaint with the supervisory authority of the country where you live, where you work, or where you believe the problem occurred (GDPR Article 77). In Turkey you can apply to us first and then, if our answer does not satisfy you, complain to the Personal Data Protection Board (Kişisel Verileri Koruma Kurulu) under Article 14 of the KVKK. You are welcome to raise the issue with us at the address above first, and we will do our best to resolve it.

6. Legal Bases for Processing

If you are in the European Economic Area, the United Kingdom, or Turkey, we have to tell you which legal ground we rely on for each kind of processing. The article references below are to the GDPR; the matching grounds under Turkish law are in Article 5 of the KVKK.

  • Account data (your email address and account identifier): Article 6(1)(b), performance of a contract. We cannot create your account, sign you in, or keep your library available across sessions without it.
  • Audio you record or upload, and the musical features we extract from it (key, BPM, chords, genre, instruments): Article 6(1)(b), performance of a contract. Analysing that audio is the service you asked for. The audio is processed and then deleted; no copy is retained.
  • AI insights and song recognition (OpenAI, AudD): Article 6(1)(b), performance of a contract. Each request is sent only when you tap the control that starts it.
  • Analytics (Firebase Analytics): Article 6(1)(f), legitimate interests, namely understanding which features are used and where the app fails so that we can improve it. You can object to this processing at any time by writing to us, and where local law requires consent for analytics we rely instead on Article 6(1)(a) and on the choice you make in the consent dialog.
  • Advertising (Google AdMob, Google User Messaging Platform, Apple AdServices attribution): Article 6(1)(a), consent, collected through the Google consent dialog in the EEA and the UK and through the Apple App Tracking Transparency prompt on iOS. If you decline, we still show non-personalised ads, which rest on Article 6(1)(f), our legitimate interest in funding the free tier. You can withdraw consent at any time, and withdrawing it does not affect processing that already took place.
  • Crash reporting (Sentry): Article 6(1)(f), legitimate interests, namely keeping the app stable, diagnosing crashes, and preventing abuse.
  • Subscriptions (RevenueCat, Apple): Article 6(1)(b), performance of a contract. We have to validate your purchase and entitlement before Premium features unlock. Apple, not us, is the seller of record and keeps the payment and tax records that the law requires it to keep.
  • Feedback and support messages: Article 6(1)(b), performance of a contract, when you write to us for help with the app, and Article 6(1)(f), our legitimate interest in improving SoundBud, when you send us a suggestion.

7. How Long We Keep Your Data

We keep each kind of data only as long as it is needed for the purpose it was collected for, and no longer.

  • Audio you record or upload: deleted when the analysis finishes. It is held only in the temporary working space of the analysis function and never written to a database or object storage, so no copy is left behind.
  • Account data (email address, account identifier, library entries): kept until you delete your account. Deleting your account removes it from our systems.
  • Feedback and support messages: kept until you delete your account. Deleting your account also deletes the messages linked to your email address; if a record cannot be removed, your email address is stripped from it.
  • Analytics data (Firebase Analytics): kept for 14 months from your last activity, and then deleted automatically.
  • Crash reports (Sentry): kept for 90 days and then deleted automatically.
  • Subscription records: held by Apple and RevenueCat for as long as their own policies and the accounting rules that apply to Apple require. On our side we keep only your current entitlement status, which goes when your account goes.

8. International Data Transfers

SoundBud is developed in Turkey and the services it relies on are not all in the same place. Audio analysis runs on AWS Lambda in the EU (Stockholm, eu-north-1), and crash reports are stored by Sentry in the EU (Frankfurt), so neither of those leaves the European Economic Area. The other services we use (OpenAI, AudD, Google for Firebase and AdMob, and RevenueCat) are operated by companies based in the United States, so data sent to them may be processed there or in other countries outside the EEA and Turkey. Those transfers are made under the European Commission Standard Contractual Clauses, which each of these providers includes in its data processing terms, together with the additional safeguards set out in those terms. Under Turkish law the same transfers rely on Article 9 of the KVKK, using the standard contract published by the Personal Data Protection Board where one applies, and otherwise your explicit consent. If you want more detail about a specific transfer, write to us at: info@alpaconaudio.com

9. Children’s Privacy

SoundBud is not intended for children under 13. We do not knowingly collect data from children.

10. Changes to This Policy

We may update this policy. We will notify you of any material changes in the app or through other means.

11. Apple App Store Terms

These Terms are between you and Alpino Tech (Alp Kurbetci), not between you and Apple. Apple is not responsible for SoundBud or for its content. Apple has no obligation to provide any maintenance or support for the app; if you need help, write to us and not to Apple. If the app fails to conform to any warranty that applies to it, you may notify Apple and Apple will refund the purchase price of the app, if any; to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the app. We, not Apple, are responsible for addressing any claim that the app or your use of it infringes intellectual property rights, fails to meet a legal requirement, or gives rise to a product liability or consumer protection claim. You confirm that you are not located in a country subject to a United States government embargo or designated by the United States government as a terrorist supporting country, and that you are not listed on any United States government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of these Terms, and once you accept these Terms Apple has the right to enforce them against you as a third-party beneficiary.

12. Governing Law and Jurisdiction

These Terms are governed by the laws of the Republic of Turkey, without regard to conflict of law rules. Any dispute arising out of these Terms or out of your use of the app falls under the jurisdiction of the courts and enforcement offices of Istanbul, Turkey. If you use SoundBud as a consumer, nothing in this section removes the protection of the mandatory consumer law of the country where you live: you keep every right that law gives you, including the right to bring a claim before the consumer arbitration committee or the consumer court of your own place of residence.

13. Contact

For questions about these Terms, contact us at: info@alpaconaudio.com

Advertisement Policy

SoundBud uses Google AdMob to display advertisements within the app.

  • Ads may be personalized based on your device settings, general location, and in-app behavior.
  • We do not collect, use, or share sensitive personal data (such as your name, contact information, or precise location) for advertising purposes.
  • Ad personalization is handled by Google under their own privacy policies and ad-serving technologies.
  • On iOS devices, SoundBud complies with Apple’s App Tracking Transparency (ATT) requirement by asking for your permission before enabling ad personalization. If you decline, only non-personalized ads will be served.
  • Every interstitial ad request includes a short list of topic keywords derived from the persona you picked during onboarding, so the ads match what the app is about. The keywords describe the topic, not you, and they are sent whether or not you allowed tracking.

You can manage your ad personalization preferences through your device settings or by visiting: https://myadcenter.google.com/

For more information, refer to Google’s Ad Policies.

European Union and UK users

Before any ad is requested, we display Google’s Consent Management dialog (User Messaging Platform / UMP) in compliance with GDPR. You can choose to accept personalized ads, manage individual ad partners, or decline all tracking. Your choice is stored locally on your device and can be reset at any time by visiting iOS Settings → Privacy & Security → Tracking, or by reinstalling the app.

Users outside the EU/UK

Including Turkey, US, and other regions: the GDPR consent dialog does not appear. Ads default to your iOS App Tracking Transparency (ATT) setting (non-personalized unless you grant tracking permission). California residents see a separate CCPA opt-out dialog under the same flow.

Identifier for Advertisers (IDFA)

When you grant ATT permission, Google AdMob may use your IDFA to deliver targeted ads. The IDFA can be reset at any time via iOS Settings → Privacy & Security → Tracking → Reset Advertising Identifier.


Open Source Licenses

SoundBud uses several open-source libraries and models, and this website uses two open-source typefaces. Below is the required attribution and license notice for each. The full LGPL-3.0, LGPL-2.1, and GPL-3.0 texts are also bundled inside the iOS app under Settings → Open Source Licenses.
