Privacy Policy

Last updated: April 13, 2026

PDFSpark is a free, no-account REST API operated by SoftVoyagers. This policy explains what the service does and does not process when you convert HTML or URLs to PDF. The policy is written in plain language and describes the actual behaviour of the system — not aspirations.

At a glance

• No account, no sign-up, no API key. We do not know who you are.
• We do not persist the HTML, URL content, or generated PDF. Rendering happens in memory and the PDF is streamed back in the HTTP response.
• We do not sell, rent, or share request content with third parties.
• We keep short-lived operational logs (IP, user-agent, path, status, latency) to run the service reliably and block abuse.
• We use Microsoft Azure Application Insights for error and performance telemetry.
• The marketing website does not set first-party analytics cookies.

Who operates PDFSpark

PDFSpark is operated by the SoftVoyagers team. For privacy questions, email contact@softvoyagers.com.

What you send us

When you call the API, your request body contains either HTML content or a URL that you want rendered. PDFSpark passes that payload into a headless Chromium instance, generates a PDF, and returns it in the HTTP response. The request body exists in server memory for the lifetime of that single request and is not written to disk.

What we store

We do not store:

• The HTML you submit.
• The content rendered from URLs you submit.
• The generated PDF.
• User accounts, email addresses, or personal profiles — we do not collect any.

We do keep, temporarily:

• Operational access logs — IP address, timestamp, HTTP method, path, response status, response size, user-agent, and a generated per-request ID. Retained for up to 30 days to diagnose outages, investigate abuse, and compute aggregate usage. Not linked to a user identity because we do not have one.
• Rate-limit counters — in-memory counters keyed on IP, used to enforce fair use. Reset on process restart.
• Error and performance telemetry — sent to Azure Application Insights (hosted in Germany West Central). Includes exception traces, request timing, and dependency calls. Subject to Microsoft’s data processing terms.

What we do not do

• We do not sell, rent, lease, or trade any data about you or your requests.
• We do not use your submitted HTML, URLs, or PDFs for any secondary purpose — no training data, no analytics, no indexing.
• We do not set advertising or third-party tracking cookies.

URL rendering and third parties

When you submit a URL, PDFSpark fetches and renders that URL from our server. The destination website will see a request originating from our Azure infrastructure, including the user-agent we use. That destination website’s privacy policy applies to what it does with its own server logs. PDFSpark does not share anything about you with the destination — we do not have anything to share.

Cookies

The pdfspark.dev marketing site uses one piece of browser storage: localStorage key sv-theme to remember your light/dark mode preference. That value never leaves your browser. No advertising, analytics, or tracking cookies are set.

Security

See the Security page for details on transport security, SSRF protections, and how to report vulnerabilities.

Children

PDFSpark is a developer tool and is not directed at children under 13. We do not knowingly collect data from children.

Changes to this policy

If we materially change how the service handles data, we will update this page and bump the “Last updated” date. Because we do not have your email, we cannot notify you directly — please re-read this page if privacy is critical for your use case.

Contact

Privacy questions and data-subject requests (GDPR / CCPA): email contact@softvoyagers.com. Because we do not hold user profiles, most “delete my data” requests have nothing to delete — but we will respond.
