1. Binding Agreement
These Terms of Service constitute a comprehensive legal agreement between you and mscmn2k. By installing and using the App, you confirm irrevocable acceptance of these terms. If you disagree with any part of these terms, you must delete the App immediately and discontinue use.
2. Description of Services
The App provides the following features:
- Auto Clean — multi-stage cleaning using a 100 to 500 Hz sine sweep, designed to push water out of the speaker chamber.
- Manual Clean — user-controlled sine-tone generation across 0 to 550 Hz for targeted dust dislodging.
- Vibrate Clean — haptic motor vibration in Low, Medium, and Strong patterns to shake out lint.
- Speaker Quality Test & Frequency Response Test — diagnostic playback so you can hear distortion, clipping, or band drop-outs.
- Sound Boost— system-level loudness enhancement via Android’s LoudnessEnhancer API.
3. Safe Usage Guidelines
Before and during use of cleaning features, you agree to:
- Set device volume to maximum for sound-based cleaning to be effective.
- Place the device on a flat surface with the speaker facing downward so freed droplets fall away.
- Use a clean, dry cloth to absorb moisture wiped from the speaker grille.
- Avoid running high-frequency modes near infants, sound-sensitive individuals, or animals.
- Disconnect headphones and external speakers before starting a cleaning cycle — the tone cannot do its job through them.
4. Hardware & Results Disclaimer
Results are not guaranteed. The App is not a professional repair service and cannot fix hardware corrosion, short-circuited logic boards, torn diaphragms, or permanently damaged drivers. The App is intended as a maintenance tool for routine speaker care. If your device shows signs of physical damage or has been heavily submerged, consult a professional repair service.

9. Indemnification
You agree to indemnify and hold harmless the Developer from any claims, damages, or expenses arising from your violation of these Terms or your misuse of any hardware-stressing feature (high-volume sweeps, prolonged vibration cycles, etc.).
10. Governing Law & Disputes
These Terms are governed by the laws of the Socialist Republic of Vietnam, without regard to its conflict of law principles. Any disputes arising from these Terms or your use of the App shall be subject to the exclusive jurisdiction of the competent Vietnamese courts.
11. Modifications to These Terms
The Developer reserves the right to update these Terms at any time. Material changes will be reflected in the “Last Updated” date above and, where appropriate, communicated in-app or on the App’s Google Play listing. Continued use of the App after such changes constitutes acceptance of the revised Terms.
