All API endpoints accept a metadata object in the request body. Set metadata.improve_mathpix to control whether Mathpix can use your request data to improve the service.

improve_mathpix	Behavior
true (default)	Images and results are accessible to the Mathpix QA team for quality improvements Results are visible in Mathpix Console
false	No image data or derived information is persisted to disk No data is available to the Mathpix QA team Results are not accessible via Mathpix Console Request metadata (status, timestamps, page count) is still retained for auditing and billing

Example metadata object with improve_mathpix disabled

{
  "metadata": {
    "improve_mathpix": false
  }
}

Supported endpoints

• POST v3/text
• POST v3/latex
• POST v3/strokes
• POST v3/batch
• POST v3/pdf
• POST v3/converter
• POST files/v1 (direct upload — see the Files API overview)
• POST files/v1/uri
• POST files/v1/jobs

For Files API submissions, metadata travels with the other OCR options: in the JSON body for POST files/v1/uri, in the options_json form field for direct uploads, and in the job-wide options for POST files/v1/jobs — where it applies to every file in the request.

Account-level setting

Mathpix can also pin improve_mathpix at the account level on your app key (for example, as part of an enterprise agreement). When an account-level value is set, it takes precedence over the per-request metadata.improve_mathpix value on all endpoints above. Contact support@mathpix.com to configure this.

Data retention

improve_mathpix controls whether your data is used for quality improvements and whether we persist it for later retrieval. For retention periods by artifact type and endpoint, see Data Retention.
