File processing
Selected PDFs, images, text, subtitle, and data files are not uploaded to a Mingmist server. Unless users independently send an output elsewhere, file content exists only in device memory, blobs, or browser-managed temporary storage.
Local browser data
| Store | Item | Purpose |
|---|---|---|
| localStorage | mingmist-theme | Remembers the light or dark appearance. |
| localStorage | mingmist-recent-tools | Remembers up to six recently used tool slugs; files and content are not included. |
| localStorage | mingmist-ocr-model-v7:<language> | Records that an OCR language model was prepared successfully; this is a marker, not the model itself. |
| IndexedDB | Tesseract.js traineddata | Tesseract.js may store OCR traineddata in IndexedDB for later recognition and offline use. |
| Cache Storage | mingmist-tools-* | The service worker stores site interface and program assets. |
| Cache Storage | mingmist-ocr-runtime-v7 | The service worker stores external OCR, PDF, and font-processing runtime assets. |
Third-party programs and network requests
The hosts below provide programs, workers, fonts, or model assets. Mingmist does not send selected files as request content to these hosts. Ordinary web requests can still reveal connection metadata such as IP address, browser identification, and request time to the provider.
| Host | Resources | Purpose |
|---|---|---|
cdnjs.cloudflare.com | pdf-lib 1.17.1, PDF.js 3.11.174 and PDF.js worker | PDF creation, modification, and page rendering. |
cdn.jsdelivr.net | Tesseract.js 7.0.0 and tesseract.js-core 7.0.0 | Local OCR runtime and worker. |
tessdata.projectnaptha.com | Tesseract traineddata 4.0.0 | OCR language models. |
unpkg.com | @pdf-lib/fontkit 1.1.1 and pdf-lib-plus-encrypt 1.1.0 | Unicode font embedding and PDF encryption. |
Clear all local data
The button below clears known localStorage, Cache Storage, IndexedDB, and service-worker data under this origin. You can also use the browser site settings and choose Clear site data. OCR models and offline resources must be downloaded again afterward.
Limits
Browser extensions, the operating system, the downloads folder, and third-party sites opened by the user are outside Mingmist Tools control.
