Sonorous Privacy Policy
Introduction
Yangben Cloud (Shanghai) Network Technology Co., Ltd. ("we", "us") understands the importance of your personal information and will do our utmost to keep it secure and reliable. We are committed to maintaining your trust and protect your personal information in accordance with the following principles: accountability, clear purpose, choice and consent, minimum necessity, security, participation of the individual, and openness and transparency.
Please read this Privacy Policy carefully before using Sonorous (the "App"). The App is a mobile application that converts web articles or text into speech for listening. Its core function is to turn a link or text that you provide into audio for you to listen to.
1. How we collect and use your personal information
We collect and use your personal information only for the purposes set out in this Policy.
1.1 Registration and sign-in
To create an account, you may register with an email address or a mobile phone number. If you register with a mobile phone number, we will send you an SMS verification code to verify that the number belongs to you. This requires providing your mobile phone number to our SMS service provider.
Information collected: email address or mobile phone number, password, nickname.
Purpose: creating the account, identity verification, password recovery.
Passwords are stored as one-way hashes. We cannot recover your password in plain text.
1.2 The core listening function
When you paste an article link, paste text, or import a TXT or Markdown file, we collect and process the content you submit in order to extract the article body, synthesise speech and build your listening list.
Information collected: article body text, source link, title, file content.
Purpose: extracting the article body, speech synthesis, building and displaying your listening list.
Please note: to synthesise speech, the article text to be read aloud is transmitted to the Xiaomi MiMo speech synthesis service for processing. See section 7.
1.3 Listening progress
To provide resume-from-where-you-stopped playback and listening statistics, we record your listening activity.
Information collected: playback position, audio duration, voice used, playback speed, time of listening.
Purpose: resuming playback, listening statistics, display on your account page.
1.4 Processing your purchase
The current version does not offer in-app purchases, and we do not collect your purchase information.
If paid features are introduced in the future, payment will be handled by Apple and we will not have access to your card or billing information. We would receive only the transaction receipt from Apple in order to verify the transaction and activate the corresponding entitlement.
Information collected: transaction receipt, only when a purchase is made.
Purpose: verifying the transaction and activating and maintaining paid entitlements.
1.5 Keeping the service running
To keep the service stable and secure, we keep API access logs for troubleshooting and abuse prevention.
Information collected: access time, API path, response result, necessary device and network identifiers.
Retention: as required by the Cybersecurity Law of the People's Republic of China, we retain the relevant network logs for no less than six months, after which they are deleted.
1.6 Clipboard content
When you open the App yourself, it reads the contents of your device's clipboard to identify whether it contains a link or text, and asks whether you want to add it to your listening list. Clipboard content is not uploaded to our servers and is not stored. Only after you confirm that it should be added is the content processed as described in section 1.2.
2. System permissions we request
