Privacy Policy
Last updated: October 5, 2026
1. Scope and contact
This notice describes how the AIstemify service handles account, audio-processing, transaction and technical data. The operator is an individual developer using the AIstemify brand. Contact [email protected] for privacy questions or requests. Payment and identity providers also process information under their own notices.
2. Data processed
Account data includes an account identifier, email, password hash for email accounts, Google account identifier when Google sign-in is used, account status and credit balance. Task data includes uploaded audio, original filenames, file metadata, selected operation, processing status, error information, output audio and task history. Transaction data includes pack, amount, currency, order and payment-provider references, credit movements and refund records. Infrastructure may process IP addresses, request metadata and operational or security logs. Support messages contain the information you choose to send; do not send card security codes or account passwords.
3. Purposes and service providers
We use this data to authenticate users, process audio, provide downloads, manage credits and orders, correct failures, support users and protect the service. Cloudflare provides website delivery, API hosting, D1 database and R2 object storage. Modal provides remote audio computation. Google processes sign-in information if you choose that login method. The payment provider identified at checkout processes billing data. Uploaded files can contain personal or confidential information and are transmitted to processing infrastructure; upload only material you are authorized to share for this purpose.
4. Browser storage and security
The application uses browser local storage for the authentication token and language preference. Logging out removes the application's stored login token; language preferences may remain. These mechanisms support account access and preferences. Infrastructure and payment-provider cookies may also be used in their respective flows. We use HTTPS, password hashing and account-based access controls, but no online system can guarantee absolute security. Keep your device and credentials secure.
5. File and record retention
Audio files are not guaranteed to remain available permanently. The current result-file configuration targets cleanup after seven days; removal occurs through scheduled processing and may not happen at an exact time. That result policy does not establish a seven-day deletion guarantee for original uploads, temporary processing files, database records or logs. Download results promptly. Account, transaction and support records may be retained for operating the service, resolving disputes and meeting applicable obligations. Contact us to request deletion; requests may require identity verification and some records may need to be retained. There is currently no self-service account deletion feature.
6. Cross-border processing and requests
Our providers may process data in countries other than your own, depending on infrastructure and service configuration. Contact [email protected] to request access, correction or deletion of your personal information, or to raise an objection or complaint where applicable. We will verify the requester before disclosing account data and handle requests under applicable law. This notice does not claim that all data remains in your country or that a model-training exclusion has been independently verified. Changes will be recorded in the published notice and communicated where required.
