Privacy Policy
Last updated: July 11, 2026
This policy explains how FastestPDF (https://pdf.developk.kr, the "Service") handles your personal information.
1. Files and editing data
The Service runs entirely client-side, in your browser. Uploaded PDFs, inserted images, added text and other editing data are never sent to an external server โ they are processed only in browser memory and disappear when you close the page. We do not collect sign-up, login or account information.
2. Cookies and advertising (Google AdSense)
The Service may display ads through Google AdSense. The following applies as a result:
- Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits.
- Google's use of advertising cookies (such as the DoubleClick cookie) enables Google and its partners to serve ads based on your visits to this site and other sites.
- You may opt out of personalized advertising by visiting Google Ads Settings. You may also opt out of third-party vendor cookies at www.aboutads.info.
3. Analytics
The Service uses Cloudflare Web Analytics and Google Analytics (GA4) to understand visitor traffic.
- Cloudflare Web Analytics does not use cookies and only collects aggregate, non-identifying data such as page views, approximate visitor region, and referral source.
- Google Analytics uses cookies to collect usage statistics such as pages visited, time on page, device/browser information, and approximate location. It does not collect directly identifying information (name, email, etc.). See Google's Privacy Policy for details. You may opt out using the Google Analytics Opt-out Browser Add-on.
4. Hosting and access logs
The Service is hosted on Cloudflare Pages. Standard server access logs (such as IP address and browser information) may be processed by Cloudflare for hosting and security purposes.
5. Children's privacy
The Service is not directed at children under 14 and we do not knowingly collect personal information from children.
6. Changes to this policy
This policy may be revised as needed. Any changes will be posted on this page along with an updated date.
