    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 an open-source PDF engine, running in a dedicated container on our infrastructure. Your file never goes through a third-party service.

    How to add a watermark to a PDF

    1

    Upload the PDF

    Drag or click to choose. Up to 25 MB.

    2

    Type and adjust

    Type the text (e.g. CONFIDENTIAL) and choose size, color, angle and transparency. Default: light gray, diagonal, 30%.

    3

    Download the watermarked PDF

    The watermark repeats on every page, over the content, with the transparency you chose.

    What it is for

    Confidential documents

    CONFIDENTIAL or INTERNAL USE on contracts, reports and exported spreadsheets.

    Drafts and versions

    DRAFT, SAMPLE or the version date, so nobody signs the wrong file.

    Original work

    Your name, website or company on course notes, portfolios and ebooks.

    Controlled copies

    The recipient's name on each copy, to discourage forwarding.

    Frequently asked questions

    Can I use an image or logo as the watermark?
    In this version, text only. Image watermarks are on the roadmap; for now, use the company name.
    Can the watermark be removed later?
    It becomes part of the page content. PDF editors can remove it with some effort; it is identification, not copy protection. To block copying and printing, combine it with password protect PDF.
    Does it accept accents and special characters?
    Yes. English, Spanish and Portuguese come out correctly. Non-Latin alphabets (Japanese, Arabic) are not supported in this version.
    Can I apply it to only some pages?
    No; it goes on every page. If you need to mark only part of the file, split the PDF, watermark that part and merge it again.
    Do the layout and quality change?
    No. Text, images and links stay the same; the watermark is drawn on top, with the transparency you choose.
    Does the file stay on your server?
    The PDF is processed on our server and deleted automatically within 1 day. Nobody on the team opens the file.
    Is there a usage limit?
    Free: 3 operations per day with any PDF tool, files up to 25 MB, just your email. The Pro plan unlocks unlimited use and files up to 100 MB.
    What is the best setting so it does not get in the way of reading?
    Light gray, diagonal (45°), light transparency (30%) and medium size: visible on screen and in print without covering the text.
