1. Document processing
NoblePDF is designed so supported PDF and document tools can process files in your browser without sending the selected document to a NoblePDF application server. The exact behaviour depends on the tool. The full editor reads a chosen PDF in the browser and can keep project-recovery data in the browser’s IndexedDB storage. Focused tools generally hold the selected file and generated result in browser memory until you download the output or leave the page.
Document content - including PDF bytes, extracted text, OCR results, annotations, signatures, form values and document passwords - is not intended to be sent to advertising or analytics systems. The persistent editor is served from the dedicated app.noblepdf.com application origin specifically so its local project storage does not share an origin with future public-site advertising code.
2. Request Signatures
Request Signatures is an explicit exception to NoblePDF’s normal local-document workflow. When you deliberately use this feature, NoblePDF uploads the PDF you are sending, the invited signer’s name and email address, the signing-field locations you place, and any optional message so the signer can access the request from another device. The original PDF, optional sender message and signer’s completed response are encrypted before they are written to NoblePDF’s private application storage and are not placed in a public web directory. The signer name, signer email, filename, field coordinates and operational request status remain in the private request database because they are needed to deliver, rate-limit and manage the request.
The signing response can include the signer-entered name and initials as canonical text, raster images used to place the signature, name and initials into the completed PDF, the signing date and timezone, the electronic-signature consent, completion timestamps and document/request hashes. NoblePDF does not accept an arbitrary replacement “completed PDF” from the signer. When a completed PDF is downloaded, the signer’s or sender’s browser rebuilds it from the stored original PDF, the original field definitions and the stored signing response.
Signature-request data is accessible only for the short request lifetime and is designed to be deleted within four days of creation. NoblePDF expires requests before the four-day point so scheduled cleanup has time to remove encrypted files. Cancelling a pending request disables the signing link immediately and triggers deletion of its encrypted files; if a filesystem operation cannot complete immediately, scheduled cleanup retries it. While a request is active, NoblePDF records operational events such as creation, opening, cancellation and completion times, hashes and consent. For abuse prevention and security investigation, those temporary event records also include a keyed digest of the connection IP address and a truncated browser user-agent string.
The invitation uses a high-entropy bearer token. It is initially placed in the URL fragment, which is not sent in the ordinary HTTP request for the signing page. The signing page moves the token into that tab’s session storage and removes it from the visible address. It does not fetch the PDF bytes until the recipient explicitly chooses Open document, reducing unintended document retrieval by automated email-link scanners. Anyone who obtains an unexpired signing link can access and complete the request; this first release does not independently verify that the person using the link is the named signer. Keep signing links private.
Sending invitation and completion emails necessarily provides the signer’s email address and the email contents, including the secure signing link, to the email-delivery systems used by NoblePDF. The four-day limit describes NoblePDF’s active request database and private application storage; hosting-provider disaster-recovery backups, if enabled, may follow the hosting provider’s separate backup-retention cycle and are not used to serve active signing requests. Request Signatures is an electronic-signature workflow, not a certificate-based digital-signature service. Downloadable audit records and hashes are supporting records, not an independently verifiable certificate or cryptographic signature over the finished PDF.
3. Local browser storage
The full editor can use IndexedDB, including the PdfEditorLocal database, to support local project persistence and recovery. IndexedDB is browser storage on your device. Clearing NoblePDF site data through your browser removes that local store. Standalone tools may use browser memory, workers, Blob URLs and temporary object URLs while a document is open; those are used to perform the requested operation and are not a cloud document library.
4. Website and server information
Like most websites, the web server and hosting infrastructure may process ordinary connection information needed to deliver pages securely, such as an IP address, request time, requested path, browser user-agent information and security/error logs. This information is separate from the contents of the document being edited. NoblePDF should not place document filenames, extracted document text or user-entered PDF content into URLs or server request parameters.
5. Account and billing data
When you request access to editor export, NoblePDF stores your email, a temporary hashed sign-in code, session data and Stripe customer/subscription identifiers. Stripe handles your payment details and subscription billing; NoblePDF does not store full card numbers. The editor asks our billing service whether your plan is active, but it does not send your PDF, annotations or document text with that request. Contact contact@noblepdf.com about account data or billing records. Payment records may need to be retained where required for tax, accounting or disputes.
6. Analytics
At the time represented by this release, NoblePDF does not include Google Analytics, Google Tag Manager, Microsoft Clarity, Hotjar or another third-party behavioural analytics runtime in the shipped public pages or editor. If analytics is introduced later, this policy must be updated before deployment to describe the provider, purpose, data categories, consent behaviour and retention choices. Analytics must not be built from document-derived values.
7. Cookies and billing
The editor uses a secure session cookie to keep you signed in and a request token to protect account actions. Stripe uses its own cookies and payment processing on its hosted checkout and billing pages. NoblePDF does not load advertising scripts in the editor.
8. External resources in HTML conversion
The HTML-to-PDF tool has an explicit option that can permit external assets referenced by an HTML document to load. That option is off by default. If you enable it, your browser may contact the third-party hosts referenced by the HTML itself. This is different from NoblePDF uploading your HTML file to an application server, but it can reveal ordinary network information to those external hosts. Leave the option off when converting untrusted or privacy-sensitive HTML.
9. Contact and requests
Privacy questions can be sent to contact@noblepdf.com. Documents and local editor projects can be removed from the browser storage on the device where the editor was used. Account or subscription data requests can be sent to the email above; payment records may have to be retained where required by law.
