Your inputs, documents, photos, and code never touch our servers. All operations execute inside your browser's sandbox.
We do not sell personal data, maintain invasive behavioral dossiers, or partner with cross-site surveillance networks.
Use every utility completely anonymously. No registration, no passwords, and no credit cards needed.
Persistence (like saved clean files) uses your local IndexedDB storage. You hold total control and can wipe it anytime.
At Crefims (“we”, “us”, or “our”), accessible via Crefims.com, we believe that everyday utility software should respect fundamental human privacy. The modern web is overrun with online converters, document scrubbers, and calculators that quietly harvest uploaded documents, log confidential code, and monetize personal telemetry.
Crefims was built on a contrarian architectural premise: Radical Client-Side Processing. This Privacy Policy details our data governance model, outlines what limited technical telemetry is collected by our edge delivery network, and explains your rights under global privacy frameworks including the GDPR, CCPA/CPRA, and PIPEDA.
Absolute Zero-Knowledge Payload Guarantee
When you use any utility on Crefims, your payload data resides exclusively in your device's volatile RAM or local sandboxed storage. We have engineered our platform so that we technically cannot view, record, intercept, or monetize your content.
Specifically, we NEVER receive or store:
To understand how your data remains completely private, it helps to understand modern web standards. Unlike legacy websites that require sending your file to a server for processing, Crefims leverages cutting-edge browser APIs:
Binary byte streams are decoded and reconstructed directly in your computer's memory without transmitting bytes over network sockets.
Once a page loads, you can physically disconnect your Wi-Fi or turn on Airplane Mode, and the tools will continue to run with identical accuracy.
Crefims uses your browser's isolated, origin-restricted client storage mechanisms to enhance your user experience:
LocalStorage: We store small configuration preferences such as your theme toggle (theme: “dark” | “light”) and local form drafts for the “Request a Tool” page. This data is strictly local and never synchronized with any remote cloud account.
IndexedDB (crefims_file_privacy_inspector_v1): When you sanitize a file with the File Privacy Inspector, the clean file is saved to your browser's IndexedDB so you can re-download it later without re-uploading. This file never leaves your local hard drive. You can delete individual files or wipe the entire database with 1 click using the “Clear All Files” button.
To maintain service reliability, prevent abusive denial-of-service attacks, and understand which tools are most useful to our community, we collect strictly aggregated, non-identifying telemetry:
1. Aggregated Analytics (Google Analytics): We use Google Analytics (measurement ID G-DZ7KWHMVJW) with IP Anonymization enabled. Google Analytics aggregates basic navigational metrics such as page visits, referring domains, device category (desktop vs mobile), browser type, and operating system. No personally identifiable information (PII) is transmitted, and User-ID cross-device tracking is disabled.
2. Infrastructure Edge Server Logs: Our content delivery network (AWS CloudFront / Edge CDN) records standard HTTP request logs (IP address, user-agent string, timestamp, and requested URL). These logs are utilized exclusively for volumetric DDoS mitigation, threat detection, caching efficiency, and CDN health monitoring, and are routinely deleted after standard operational retention windows.
Crefims does NOT use third-party advertising cookies, retargeting pixels, or behavioral tracking cookies.
The only cookies that may be set are strictly essential technical cookies or standard measurement cookies deployed by Google Analytics. You can instruct your browser to block or alert you about cookies; however, Crefims will continue to function seamlessly even if you disable cookies completely.
Under the General Data Protection Regulation (EU Regulation 2016/679) and the UK GDPR, European residents enjoy specific privacy entitlements:
Legal Basis for Processing: We process minimal edge server logs on the basis of Legitimate Interests (Article 6(1)(f) GDPR) to maintain platform cybersecurity and uptime.
Data Minimization by Design: Because we do not store, process, or transmit your files or input data on our servers, Crefims operates under an innate “Privacy by Design and by Default” model (Article 25 GDPR).
Your Data Subject Rights: You have the right to request access, rectification, erasure (“Right to be Forgotten”), restriction of processing, and data portability regarding any personal data we hold. Since we do not collect personal accounts, there is virtually zero personal data associated with you on our servers. For any queries, you may contact our privacy desk.
Under the California Consumer Privacy Act (CCPA) and the California Privacy Rights Act (CPRA):
Crefims is a general audience digital utility suite. We do not knowingly collect, solicit, or maintain personally identifiable information from children under the age of thirteen (13). If you believe a child has provided personal information to us, please reach out through our contact channel, and we will take immediate steps to delete any such telemetry.
All web traffic to Crefims is enforced via HTTPS using Modern Transport Layer Security (TLS 1.3 / TLS 1.2) encryption with HTTP Strict Transport Security (HSTS) headers. This ensures that static assets, WebAssembly modules, and client-side scripts are delivered to your browser untampered by intermediaries.
We may update this Privacy Policy from time to time to accommodate new browser utilities, regulatory updates, or architectural enhancements. When modifications are made, the revised policy will be posted on this page with an updated “Last Updated” timestamp. We recommend reviewing this document periodically to stay informed about how we maintain your privacy.
