Sinuose is an audio enhancement web and mobile application that allows users to upload MP3 audio files and apply professional-grade processing enhancements. The Service includes audio equalization, compression, loudness normalization, and stereo enhancement using deterministic digital signal processing algorithms powered by FFmpeg. The Service also provides a personal library for storing enhanced tracks, social features for connecting with other producers, and subscription-based premium tiers with additional capabilities.

To use certain features of the Service, you must create an account. You agree to: • Provide accurate, current, and complete information during registration • Maintain and promptly update your account information • Maintain the security of your account credentials • Accept responsibility for all activities that occur under your account • Notify us immediately of any unauthorized use of your account You must be at least 13 years of age to create an account and use the Service. By creating an account, you represent that you meet this age requirement.

Sinuose offers a free tier and a paid Premium subscription. The Premium plan is billed weekly at $2.99/week. Paid subscriptions are processed through Apple's In-App Purchase system (for iOS) or through our payment processor Adapty. Free Trial: New Premium subscribers may be eligible for a 3-day free trial. The trial begins when you subscribe and automatically converts to a paid subscription at the end of the trial period unless cancelled. Each user is eligible for one free trial only. Auto-Renewal: Premium subscriptions automatically renew at the end of each weekly billing period unless cancelled before the renewal date. The subscription fee will be charged to your payment method on file. Cancellation:You may cancel your subscription at any time through your Apple device settings (Settings → Apple ID → Subscriptions) or through the applicable platform's subscription management. Cancellation takes effect at the end of the current billing period — you will retain access to Premium features until then. Refunds:Refund requests for subscriptions purchased through Apple are subject to Apple's refund policy. We do not process refunds directly for In-App Purchases. Price Changes: We reserve the right to change subscription prices. Existing subscribers will be notified in advance of any price changes, and the new price will apply at the next renewal date.
