Introduction & Scope
Welcome to Paperknife Solo (accessible via our primary website domain). We provide free, browser-based productivity utilities including PDF manipulation tools, image converters & editors, and high-precision online calculators.
This Privacy Policy describes our practices regarding the collection, use, retention, and disclosure of information when you use our website, tools, and services. By accessing or using Paperknife Solo, you acknowledge that you have read, understood, and consented to the practices described herein. If you disagree with any terms in this policy, please discontinue use of our services immediately.
Information We Collect
We believe in strict data minimization. We only collect the minimal information necessary to deliver, maintain, and optimize our tools:
A. Information You Voluntarily Provide
When using our utility tools, we do not require account registration, passwords, credit card information, or phone numbers. The only time we receive direct personal information is if you voluntarily contact us via our contact form or direct email (kumardeepu9873@gmail.com), in which case we receive your name, email address, and message contents.
B. Files and Documents You Upload
When you use our PDF and Image tools (such as Merge PDF, Compress PDF, Text to PDF, Image Compressor, etc.), your files are temporarily transferred over an encrypted connection to our server strictly to execute the requested operational script (e.g., converting, compressing, watermarking, or extracting data). We do not claim ownership, read, catalog, or mine the contents of your files.
C. Automatically Collected Technical Data (Log Files)
Like standard web applications, our web servers automatically generate standard server access log files. This information includes:
- Internet Protocol (IP) address (anonymized where applicable)
- Browser user-agent, operating system, and hardware architecture
- Referring / exit pages and URL navigation paths
- Date, time stamp, and request duration
- HTTP response codes and data transfer volumes
Log data is utilized solely for technical troubleshooting, server load balancing, preventing DDoS attacks or automated abuse, and ensuring overall server stability.
File Security & Automated Deletion Lifecycle
Document security is our highest architectural priority. Here is how your files are safeguarded:
All file transfers between your browser and our server are encrypted with industry-standard 256-bit SSL/TLS protocol.
Files are held only long enough for you to download them. Automated cron cleanups purge files permanently within 1–24 hours.
Processing is fully automated by code. No human or third-party ever views, audits, or extracts information from your documents.
Google AdSense & Third-Party Advertising Policy
Paperknife Solo is monetized in part through advertisements served by Google AdSense and authorized advertising partners to keep our tools 100% free for everyone.
Google AdSense Compliance Disclosures:
- Third-party vendors, including Google, use cookies (such as the DoubleClick DART cookie) to serve advertisements based on a user's prior visits to this website or other websites across the Internet.
- Google's use of advertising cookies enables it and its certified advertising partners to serve personalized ads to you based on your visit to Paperknife Solo and other websites.
