Privacy Policy | Audio Enhancer AI

Who Is Responsible

Audio Enhancer Ai at audioenhancerai.net is operated by Xiaoming Qian, an individual operator responsible for the personal information described in this policy. Contact address: Building 2, Chuncheng Daguan Lingxiu Yukun Yuan, Guanshang Subdistrict, Guandu District, Kunming, Yunnan, China. Privacy requests can be sent to [email protected].

Local Processing and Cloud Processing

Free browser mode: Your selected audio and enhanced result are processed on your device and are not uploaded to our servers for enhancement. The website still receives ordinary requests to serve pages and download processing software, which can expose technical information such as an IP address. Downloaded files remain on your device under your control.

Pro cloud mode: When you start a cloud task, your audio is uploaded to object storage. Our servers and Replicate, the AI inference provider running the enhancement model, receive the audio or its file URL to perform the task. Longer recordings may be divided into segments for processing and then merged.

Cloud file links: Uploaded cloud audio and enhanced results use file URLs that can be accessed by anyone who obtains the URL, without signing in. Account protection for task history does not make these file URLs private. Do not share them with unintended recipients. Use local mode for recordings you do not want uploaded, and do not upload confidential or sensitive recordings unless you have the necessary permissions and this access arrangement is suitable for them.

Information We Handle

Account information: Email, name, profile image, sign-in provider identifiers, authentication tokens, session information, and account preferences. Google sign-in provides the profile information needed to create or authenticate your account.
Cloud task information: Source audio, original filename, file URLs, duration, format, enhanced audio, model and processing settings, task identifiers, progress, errors, timestamps, and processing-time usage. Recordings may contain other people's voices or personal information.
Technical information: IP address, browser and request information, security and diagnostic logs, and approximate country where an IP lookup is used. These help operate the website, troubleshoot errors, and prevent abuse.
Purchase information, when checkout is available: Customer and transaction references, purchased package, amount, currency, payment status, and credit records. Payment details are submitted to the payment provider; our application does not store full card numbers or card security codes.
Support information: Your email and the messages, task references, or attachments you choose to send us.

We do not need sensitive personal information for ordinary enhancement. Do not upload recordings containing it unless you have a lawful basis and all required permissions. We do not use this enhancement service to identify speakers through voice biometrics.

Purposes and Legal Grounds

We process the necessary information to provide accounts, requested cloud enhancement, task history, processing-time balances, payments, and customer support. Where applicable, this processing is necessary to perform our contract with you or take steps at your request before a purchase.

We use relevant technical and task information to maintain security, investigate errors or abuse, enforce our Acceptable Use Policy, and respond to lawful requests. Depending on applicable law, the grounds are legal obligations or legitimate interests in operating a safe and reliable service, where that ground is recognized and does not override your rights.

Where consent is legally required for a particular activity, we must obtain it separately. Agreeing to the Terms of Service, visiting the website, or reading this policy does not itself constitute that consent. You may withdraw consent by contacting us, without affecting earlier lawful processing. If you choose not to provide information necessary for a cloud task or account, we may be unable to provide that feature; free local enhancement does not require an account.

Our use of your uploaded audio is limited to delivering requested processing, support, security, and legal compliance. We do not sell your audio or enhanced results, or use them to train general AI models. Third-party handling is subject to the provider's applicable terms and the processing arrangement; this policy does not promise that every provider has identical retention practices.

Providers and Other Disclosures

We share information only as needed for the relevant service or lawful purpose:

Replicate: Receives cloud audio, audio URLs, model settings, and processing metadata to run AI enhancement. Its API data-retention documentation describes its own retention, which is separate from copies stored by Audio Enhancer Ai.
Cloudflare R2 and hosting infrastructure: Store and deliver cloud audio and results, and handle the network requests and technical information needed to serve the website.
Google: Provides sign-in and receives the information needed for authentication when you choose Google sign-in.
Stripe, when checkout is enabled: Processes payments and billing details and sends transaction information needed to credit your account and handle payment issues.
Resend: Receives recipient addresses and message contents when sending account or service emails.
IPinfo, when an IP-based country lookup is configured: Receives the IP address for an approximate country lookup.

Relevant information may also be disclosed to authorized support or safety reviewers, professional advisers, or authorities where necessary for security, a legal obligation, or a dispute. We do not routinely send audio files to payment providers. We do not currently enable advertising trackers or third-party analytics tracking. Any future optional tracking must be disclosed and obtain consent where required before activation; see our Cookie Policy.

International Processing

Our operator is based in China. Hosting, authentication, storage, email, payment, and AI providers may process information in other countries, including countries with different privacy laws. Cloud enhancement therefore may involve processing outside your country of residence.

Where applicable law requires a transfer mechanism, additional recipient information, or separate consent, those requirements must be met before the relevant transfer. Acceptance of this policy is not a substitute for them. Contact us to request details of the recipients, processing locations, and safeguards applicable to your information.

Retention and Deletion

Local audio: We do not retain an uploaded server copy from free browser processing. You control files saved on your device.
Cloud source files and intermediate segments: The service attempts cleanup when a task succeeds or fails. Interrupted uploads, failed cleanup, or other technical errors can leave files behind; there is no guaranteed automatic deletion deadline for every uploaded file.
Cloud results and task history: Results remain available for preview and download until the task is deleted or the data is otherwise removed. The service currently has no fixed automatic expiry for completed results. You can delete completed or failed tasks from task history to remove associated stored files and the task record. Active tasks cannot currently be deleted; contact us for assistance.
Account closure: Account deletion does not necessarily delete all audio objects in storage. Delete finished tasks first or contact us to request file deletion, including orphaned uploads. We verify ownership before acting on requests.
Account, transaction, support, and security records: Retention depends on the account or support relationship, the time needed to investigate an issue, and applicable accounting, legal, or dispute requirements. We retain only what remains necessary for those purposes. Provider records and any backups may have separate retention schedules; deletion may not immediately remove copies already downloaded by others.

Contact us for deletion requests or more information about retention of a particular record. We do not promise permanent file availability; download results you need to keep.

Your Rights and Choices

Subject to applicable law, you may request access to, a copy of, correction of, or deletion of personal information; restriction of or objection to processing; portability where available; withdrawal of consent; and an explanation or review of a decision affecting your access. You may also complain to the competent privacy authority.

Email [email protected] from your account address where possible, describing the request and relevant task references. Do not include full payment card details or unnecessary identity documents. We may request proportionate information to verify identity and ownership and will respond within the time required by applicable law. If an exception prevents fulfilling a request, we will explain it. Browser settings let you clear stored preferences and cookies, but do not delete files held in cloud storage.

Security and Children

We use account access controls and other technical and organizational measures to protect information. No transmission or storage system is completely secure; in particular, cloud file URLs have the access limitations described above.

The service is not directed to children below the age at which they can lawfully consent to data processing without a parent or guardian. If you believe a child has provided personal information without the required authorization, contact us so we can investigate and address it.

Updates and Contact

We will publish changes with an updated date and notify you of material changes through the website or, where appropriate, email. Additional consent will be sought where required.
