Factflew is a digital file certification service built with a strict focus on data minimization and user privacy.
Driven by the innovative "Unknow Your Customer" (UYC) architectural concept, Factflew does not require your name, email, phone number, or any identity verification for its core functionality. The system only interacts with a technical pseudonym โ a unique FF-code generated on your device.
How it works: Your source files never leave your device. The SHA-256 cryptographic hash is calculated locally on your device using the Web Crypto API. Only this digital fingerprint is transmitted to be registered permanently with a reliable timestamp in the Polygon blockchain network.
Key Features: โข True Anonymity: No registration, no tracking, and zero email collection. โข Local Processing: Maximum security as files are processed entirely on your device. โข Immutable Proof: Once confirmed on-chain, your certificate provides permanent, public verification of the file's existence at that exact moment. โข Flexible Pricing: Pay a flat rate of โฌ1 per single certificate or choose device-based unlimited subscription plans.

Factflew's answer
Unlike traditional timestamping or document-tracking services that demand your files or personal data be uploaded to centralized servers, Factflew operates on zero-knowledge and cryptographic principles. You retain full ownership, privacy, and control of your actual content while securing unalterable proof of existence.
GhostMyData's answer:
More coverage (1,500+ brokers), lower price ($9.99/mo vs $14.98 for Incogni), free scan with 3 free trial removals (no credit card), family plans covering 5 members, and transparent compliance reporting. We also use dual search engines (Google + Brave) to find exposures competitors miss.
Factflew's answer
Factflew is built on the UYC (Unknow Your Customer) architectural philosophy. It allows anonymous blockchain file-hash registration, ensuring absolute user data privacy without requiring unnecessary personal details, account creation, or KYC.
GhostMyData's answer:
We cover 1,500+ data broker sites โ 3.5x more than Incogni and 17x more than DeleteMe's auto-removal. We send legally-enforceable CCPA deletion requests, not just opt-out forms. And we publish a live broker compliance report showing which brokers actually delete your data and which ignore requests.
Factflew's answer
Factflew serves a universal audience ranging from everyday consumers to professionals, driven by a common need to eliminate information asymmetry and secure undeniable proof in high-stakes moments: Everyday Consumers & Mass Market: People navigating high-value domestic risksโsuch as property rentals (check-in/check-out conditions), vehicle usage and parking incidents, purchases and returns, healthcare tracking, labor relations, and personal safety documentation. Professionals & Field Workers: Transport and logistics operators, educators, and service providers who need instant verification of assets, shift handovers, and cargo states. Tech-Savvy Creators & Developers: Independent creators, software engineers, and researchers requiring unalterable, privacy-first cryptographic timestamping for code versions, digital art, and intellectual property.
GhostMyData's answer:
Privacy-conscious individuals and families who want their personal data removed from people-search sites and data brokers. Also businesses protecting employees from social engineering attacks that exploit exposed personal data.
Factflew's answer
Factflew was created out of a necessity to solve a fundamental flaw in modern digital infrastructure: the invasive requirement to surrender private data just to prove ownership. It was built from the ground up by an independent developer to put absolute data sovereignty back into the hands of the creator.
GhostMyData's answer:
I discovered my full name, home address, phone numbers, and family members' details were publicly listed on hundreds of people-search sites โ available to anyone for under a dollar. After spending 40+ hours manually submitting opt-out forms, I realized the data just comes back. So I built GhostMyData to automate the entire process.
Factflew's answer
Cryptographic hashing (such as SHA-256) combined with secure public ledger/blockchain integration, designed with a minimalist and privacy-first web architecture.
GhostMyData's answer:
Next.js, React, TypeScript, Prisma ORM, PostgreSQL, Vercel, Resend for transactional email, Amazon SES for broker CCPA emails, Google and Brave Search APIs for exposure detection.
Factflew's answer
Factflew is built to protect individuals and professionals across diverse everyday risk scenarios rather than only traditional corporate clients. Key user groups include:
Everyday consumers managing property rentals, vehicle conditions, and purchase disputes
Drivers and logistics personnel logging transit and transport states
Independent creators, software developers, and researchers protecting intellectual property priority
Professionals in healthcare, education, and labor relations securing daily operational milestones and agreements
GhostMyData's answer:
I built GhostMyData because I was tired of finding my personal information โ home address, phone numbers, family members โ plastered across dozens of data broker sites. After trying other services, I realized most only cover a fraction of brokers and charge premium prices for basic scans. GhostMyData scans 1,500+ data broker sites, sends legally-backed CCPA deletion requests on your behalf, and tracks every removal to completion. The automated removal pipeline handles everything from opt-out form submissions to verification that your data was actually taken down. We also offer family plans so you can protect your entire household under one subscription, and our daily privacy digest keeps you informed without email overload. The whole platform is designed around transparency โ you see exactly what was found, what's been removed, and what's still in progress.
