14.1 Microphone Usage — Critical Disclosure

The RECORD_AUDIO permission is required by Android to access microphone input for any purpose, including real-time analysis. Our use of this permission is solely and strictly for real-time acoustic analysis as described herein. Specifically:

• YES — The microphone is used extensively for real-time acoustic analysis, including SPL measurement, spectrum analysis, RTA, spectrogram, impulse response capture, room acoustics measurement, THD, SNR, frequency response testing, and microphone testing.
• NO — Audio captured via the microphone is never recorded to storage — not to your device's internal storage, not to an SD card, and not to any remote server or cloud service.
• NO — Audio data is never transmitted over a network connection, Wi-Fi, Bluetooth data channel, or any other communication interface.
• NO — The App does not perform voice recognition, speech-to-text transcription, conversation monitoring, speaker identification, or any other form of linguistic or biometric processing of audio content.
• NO — Audio does not persist beyond the active measurement session. Audio data exists exclusively in volatile RAM during active measurement and is immediately and permanently discarded when the measurement ends, a new measurement begins, or the App is closed. No audio ever touches non-volatile storage.

14.2 Data Stored Locally on Your Device

The following categories of data may be stored locally on your device:

• Calibration Profiles — Microphone sensitivity and reference-level calibration data you configure within the App;
• Measurement Results — Saved SPL readings, spectrum captures, THD measurements, SNR measurements, frequency response curves, impulse responses, and room acoustics data that you explicitly choose to save;
• Exported Files — PDF and CSV reports generated at your request, saved to your device's accessible storage; and
• User Preferences — Application settings, UI preferences, measurement configuration, and display options.

This locally stored data is under your control. You may delete it at any time by clearing the App's data within Android Settings or by uninstalling the App.

15.1 Data Controller

For the purposes of the GDPR, Strategia-X acts as the data controller for personal data processed in connection with your use of DeviceLab Audiophile. Contact details are provided in Section 25.

15.2 Legal Bases for Processing (Article 6)

We rely on the following legal bases under Article 6 GDPR for processing personal data in connection with the App:

• Article 6(1)(a) — Consent: For the serving of personalized advertising via Google AdMob, where you have provided consent through the UMP consent dialog. You may withdraw consent at any time without affecting the lawfulness of processing prior to withdrawal.
• Article 6(1)(b) — Performance of Contract: For processing necessary to provide you with the App's functionality pursuant to these Terms (e.g., local storage of measurement data you save, preferences). Audio data captured via the microphone is processed under this basis for the purpose of providing real-time measurement functionality. Because audio data exists only in volatile memory and is never stored or transmitted, the privacy impact of this processing is minimal.
• Article 6(1)(f) — Legitimate Interests: For serving non-personalized advertising (where you have not consented to personalized ads), for fraud prevention, and for security purposes, where our legitimate interests are not overridden by your rights and freedoms.

15.3 Children's Consent (Articles 7 and 8)

Where consent is the legal basis for processing, consent from children under 16 (or the applicable age threshold in your member state) must be provided or authorized by the child's parent or guardian. We rely on Google's UMP and age-gate mechanisms to facilitate this requirement. See Section 2.

15.4 Transparency and Information Rights (Articles 12–14)

We provide clear, concise, and accessible information about our data processing practices through these Terms and our Privacy Policy, in compliance with Articles 12–14 GDPR. Information is provided in plain language, free of charge, and without undue delay.

15.5 Your Rights (Articles 15–22)

Subject to applicable exceptions and limitations under the GDPR, you have the following rights with respect to your personal data:

California residents have the following rights under CCPA/CPRA, subject to applicable exceptions:

• Right to Know (§ 1798.100, § 1798.110, § 1798.115): Request disclosure of the categories and specific pieces of personal information we have collected, the sources, the business purposes, and the categories of third parties with whom we share it.

16.3 Submitting a CCPA/CPRA Request

We will respond within 45 days as required by law, with a possible extension of an additional 45 days where reasonably necessary with prior notice.

16.4 CalOPPA Compliance

In compliance with the California Online Privacy Protection Act (CalOPPA), we make our Privacy Policy conspicuously available, clearly identify the categories of personally identifiable information we collect, disclose whether third parties may collect PII through the App, and indicate how we respond to Do Not Track signals. We honor Do Not Track and Global Privacy Control (GPC) signals to the extent technically feasible.

Part 312) prohibit the collection of personal information from children under 13 without verifiable parental consent. DeviceLab Audiophile is not directed to children under 13. We do not knowingly collect personal information from children under 13. If we discover that we have inadvertently collected personal information from a child under 13, we will take immediate steps to delete that information. If you are a parent or guardian and believe we may have inadvertently collected information from a child under 13, please contact us immediately at the address in Section 25. We configure Google AdMob with appropriate child-directed treatment tags where required.

17.2 Exercising State Privacy Rights

To exercise privacy rights under any of the above state laws, contact us at the email address provided in Section 25 with the subject line "U.S. State Privacy Request — [Your State]." We will respond within the timeframe required by your state's applicable law. Where an appeal right exists and we deny your initial request, we will provide instructions for submitting an appeal.

DeviceLab Audiophile is developed and operated from the United States. These Terms and the App's operation are governed primarily by U.S. law. If you access or use the App from outside the United States, you do so on your own initiative and are responsible for compliance with applicable local laws.

In addition to the GDPR provisions addressed in Section 15, users in the following jurisdictions should be aware of the following:

• Brazil (LGPD): Users in Brazil have rights under the Lei Geral de Proteção de Dados (LGPD), Law No. 13,709/2018, including rights of access, correction, deletion, data portability, information about sharing, and the right to revoke consent. We process data in accordance with LGPD principles of purpose limitation, necessity, and data minimization.
• Canada (PIPEDA / Law 25): Users in Canada have rights under the Personal Information Protection and Electronic Documents Act (PIPEDA) and, for Quebec residents, Law 25 (An Act to modernize legislative provisions as regards the protection of personal information). You may request access to personal information we hold about you and challenge its accuracy.
• Australia (Privacy Act 1988): Australian users may have rights under the Australian Privacy Act 1988 and the Australian Privacy Principles (APPs). You may request access to and correction of personal information about you, and complain about suspected privacy breaches.
• Other Jurisdictions: Users in other jurisdictions may have additional rights under local data protection laws. We will endeavor to honor reasonable requests consistent with applicable law.

To the extent a conflict exists between these Terms and mandatory provisions of the law of the country in which you are located, the mandatory provisions of applicable local law shall govern to the extent required.

DeviceLab Audiophile integrates with the following third-party services. Your use of these services is subject to their respective terms of service and privacy policies, which we encourage you to review. Strategia-X is not responsible for the data practices of any third-party service provider.

19.1 Google AdMob

Mobile advertising platform providing banner, interstitial, and other ad formats. May collect advertising identifiers, device information, and interaction data for ad targeting and measurement. Governed by the Google Privacy Policy and AdMob GDPR Guidance.

19.2 Google User Messaging Platform (UMP)

Consent management platform used to present GDPR and U.S. state law consent dialogs. Stores and communicates your consent choices to Google's advertising infrastructure. Governed by the Google Privacy Policy.

19.3 Google Play Services

Core Android platform services provided by Google, including device integrity attestation, network connectivity, and update distribution. Google Play Services may collect device and usage data as described in the Google Privacy Policy.

Strategia-X enters into appropriate data processing agreements with third-party service providers as required by the GDPR and other applicable data protection laws. The App does not integrate any third-party analytics SDKs beyond those described above, and does not share your personal data with advertisers, data brokers, or other third parties for purposes beyond those described herein.

20.1 App Updates

Strategia-X may release updates to DeviceLab Audiophile periodically through the Google Play Store. Updates may include new features, bug fixes, security patches, performance improvements, or removal of features. Some updates may be required to continue using the App. You are responsible for keeping the App updated to the current version. We are not responsible for issues arising from your use of an outdated version of the App.

20.2 Automatic Updates

If your device is configured to automatically update apps, DeviceLab Audiophile may update without specific notification to you. By enabling automatic updates, you agree that updated Terms (if any) take effect upon the update's installation.

20.3 Feature Changes

We reserve the right to modify, suspend, or discontinue any feature of the App at any time. We will endeavor to provide reasonable notice of significant changes, but are not obligated to do so for minor updates or where immediacy is required for security reasons.

20.4 Android Version Support

We may, at any time, raise the minimum supported Android version above the current minimum of Android 7.0 (API 24). If your device's Android version falls below the minimum requirement after such a change, you may continue to use the version of the App already installed but will not receive updates.

21.1 Termination by You

You may terminate your agreement with these Terms at any time by uninstalling DeviceLab Audiophile from all your devices and ceasing all use of the App. Because no account exists, no additional steps are required to deregister.

21.2 Termination by Strategia-X

Strategia-X reserves the right to suspend or terminate your access to the App, or to remove the App from the Google Play Store, at any time, with or without cause or notice, to the extent permitted by applicable law. Grounds for termination may include, without limitation: your material breach of these Terms; conduct that Strategia-X believes, in its sole discretion, is harmful to other users, third parties, or Strategia-X; or legal, regulatory, or technical requirements.

21.3 Effect of Termination

Upon termination of your right to use the App, the license granted to you under Section 9 is immediately revoked. All provisions of these Terms that by their nature should survive termination shall survive, including but not limited to Sections 8, 12, 13, 14, 15, 16, 17, 18, 22, and 23.

22.1 Governing Law

These Terms and any dispute or claim arising out of or in connection with them, their subject matter, or their formation (including non-contractual disputes or claims) shall be governed by and construed in accordance with the laws of the State of Delaware, United States of America, without regard to its conflict of law principles. The United Nations Convention on Contracts for the International Sale of Goods does not apply to these Terms.

22.2 Informal Resolution

Before initiating any formal dispute resolution proceeding, you agree to contact Strategia-X at the address provided in Section 25 and provide written notice of your dispute. We will attempt in good faith to resolve the dispute within 30 days of receiving written notice.

22.3 Binding Arbitration

If the dispute is not resolved through informal negotiation within 30 days, any dispute, claim, or controversy arising out of or relating to these Terms or the App shall be resolved by final and binding arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, except as modified herein. The arbitration shall be conducted in English, seated in Delaware, USA. The arbitrator's award shall be final and binding and may be entered as a judgment in any court of competent jurisdiction.

22.4 Class Action Waiver

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, YOU AGREE THAT ANY DISPUTE RESOLUTION PROCEEDING WILL BE CONDUCTED ONLY ON AN INDIVIDUAL BASIS AND NOT IN A CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION. IF FOR ANY REASON A CLAIM PROCEEDS IN COURT RATHER THAN IN ARBITRATION, YOU WAIVE ANY RIGHT TO A JURY TRIAL.

22.5 Exceptions

Notwithstanding the foregoing, either party may seek emergency injunctive or other equitable relief in any court of competent jurisdiction to prevent actual or threatened infringement, misappropriation, or violation of intellectual property rights, without first engaging in the informal resolution process. Nothing in this section shall prevent either party from filing a complaint with a consumer protection agency or data protection authority.

EU and UK Users: If you are located in the EU or UK, mandatory provisions of your local consumer protection law may supersede this arbitration clause and class action waiver, and you may retain the right to bring claims in your local courts.

If any provision of these Terms is held by a court or arbitrator of competent jurisdiction to be invalid, illegal, or unenforceable under applicable law, such provision shall be deemed modified to the minimum extent necessary to make it valid, legal, and enforceable. If such modification is not possible, the relevant provision shall be deemed deleted. Any modification or deletion of a provision under this section shall not affect the validity and enforceability of the remaining provisions of these Terms, which shall continue in full force and effect.

The invalidity or unenforceability of any provision in one jurisdiction shall not affect the validity or enforceability of that provision in any other jurisdiction.

Strategia-X reserves the right to modify these Terms at any time. When we make material changes to these Terms, we will:

• Update the "Last Updated" date at the top of this document;
• Post the revised Terms at www.strategia-x.com/terms/devicelab-audiophile;
• Where feasible and required by law, provide in-App notification of material changes; and
• Where required by applicable law (e.g., for changes to how we process personal data under the GDPR), obtain your renewed consent.

Your continued use of the App following the posting of revised Terms constitutes your acceptance of the changes. If you do not agree to the revised Terms, you must stop using the App and uninstall it from your device.

We encourage you to review these Terms periodically to remain informed of your rights and obligations. Non-material changes (such as typographical corrections, formatting adjustments, or clarifications that do not alter the substance of your rights or obligations) may be made at any time without notification.
