    How we handle your files

    What we collect from the upload

    Only the file you send, for as long as needed to process and return it. No additional data from the file is extracted, indexed, or sent to any third party.

    Where we process

    Rollin Host's own infrastructure, in international Tier III datacenters (Europe and US). The upload goes through temporary storage (Vercel Blob) with automatic deletion right after processing. We do not use third-party conversion APIs (smallpdf, Adobe, etc.). Processing complies with the LGPD, with safeguards for international data transfer (Art. 33).

    How long we store it

    Only as long as needed to process. The file sits in temporary storage during upload and in server RAM during processing (a few seconds), with automatic deletion right after you download the result. It never goes to backup, and we never log the content.

    What gets logged

    Operational logs without content: call timestamp, IP hash (anonymized), operation name (e.g., "merge"), file size, HTTP response code. Retention: 30 days, for debugging and security. None of your personal metadata goes into these logs.

    Cookies and tracking

    No third-party cookies in this tool. The main site uses first-party cookies for the theme (dark/light) and anonymous Google Analytics only if you consent in the CMP banner. Tool pages work even without accepting any cookies.

    Legal basis (LGPD)

    Processing happens under the basis of performance of a service requested by the data subject (Art. 7, V, of the LGPD). Since you submit the file voluntarily for processing, this is the most direct basis possible — no additional consent needed.

    Your rights

    Since we don't store your content, there is no data to access, correct, or delete after processing. You get the LGPD rights (Art. 18) by default. Questions or requests: dpo@rollinhost.com.br (Rollin Host DPO).

    Backend software

    We use Stirling-PDF, MIT open-source, running in a dedicated Docker container on our infrastructure. Auditable: github.com/Stirling-Tools/Stirling-PDF.

    Frequently asked questions

    What is OCR?
    OCR (Optical Character Recognition) reads text in images. When you scan a document, it becomes a "photo" — no digital text. OCR analyzes the image and creates an invisible text layer on top, making the PDF searchable and selectable.
    Which OCR engine do you use?
    Tesseract — Google's open-source engine, trained on millions of documents. State of the art in open source. The same engine used by Google Drive, Adobe Acrobat (partly), and many other professional tools.
    Which languages does the OCR recognize?
    Portuguese, English, and Spanish. Pick the document language before processing — it significantly improves recognition accuracy, especially for accented words.
    Does scan quality matter?
    A lot. The better the resolution (minimum 300 DPI), the better the OCR. Documents scanned at an angle, blurry, or stained have lower accuracy. For sharp documents, accuracy reaches 99%.
    Is the original PDF changed visually?
    No. OCR adds an invisible text layer over the images. Visually the PDF stays identical, but you can now select text, copy, search (Ctrl+F), and index it in search systems.
    How do I export the extracted text?
    After downloading the searchable PDF, open it in any reader (Adobe, Chrome, Foxit) and use Ctrl+A to select all the text, then Ctrl+C to copy. Paste it into any editor (Word, Notepad).
    Confidential documents?
    Processed on secure servers, discarded within seconds. No storage. For extremely sensitive documents (legal, medical), we recommend offline OCR instead of any online tool.
