Frequently Asked Questions
Everything you need to know about OSINTScan's privacy model, detection accuracy, public footprint auditing, and responsible use guidelines.
General & OSINT Fundamentals
What is OSINT?▼
OSINT stands for Open Source Intelligence. It refers to the lawful collection, processing, and analysis of publicly available information published on the open web, public directories, and publicly queryable network protocols.
What is OSINTScan?▼
OSINTScan is a privacy-first public digital footprint intelligence tool. It allows individuals, cybersecurity analysts, and privacy practitioners to search usernames, email addresses, and phone numbers to discover publicly accessible profiles and exposure signals.
Does OSINTScan find passwords or private communications?▼
No, absolutely not. OSINTScan never searches for, cracks, or exposes passwords, private direct messages, financial details, or confidential records. We exclusively query public HTTP endpoints, DNS records, and open-source indices.
Is OSINTScan free to use?▼
Yes. OSINTScan provides completely free in-memory footprint searches for lawful personal auditing, defensive research, and privacy education without subscriptions or paywalls.
Username Searches & Accuracy
Can a matching username prove someone's identity?▼
No. A matching username across different services does not prove that both accounts belong to the same person. Common handles are often registered by completely different individuals worldwide. Results represent public footprint signals that require secondary human verification.
How accurate are username search results?▼
OSINTScan utilizes multi-layered response validation (including HTTP status codes, specific error-string patterns, and page content fingerprinting) to minimize false positives. However, single-page web applications and anti-bot systems can occasionally produce ambiguous signals.
Why does a result show 'Manual Review' or 'Blocked'?▼
Some modern web applications return HTTP 200 OK for every page and render 'User Not Found' via client-side JavaScript, while other platforms deploy Cloudflare or Akamai firewalls that challenge automated queries with CAPTCHAs (HTTP 403/503). OSINTScan marks these transparently as requiring manual verification rather than making false claims.
Email & Phone Number Lookups
What information does Reverse Email Lookup provide?▼
Our email intelligence checks publicly accessible services to determine if an email is registered on major public platforms, retrieves public avatar information (such as Gravatar), and checks publicly disclosed breach databases to evaluate known exposure risks.
What information does Phone Lookup provide?▼
Phone lookups standardize international numbers (ITU-T E.164), identify geographic allocation, inspect public carrier routing to distinguish mobile lines from virtual VoIP providers, and check public registration indicators.
Can phone lookup reveal a subscriber's real-time location?▼
No. Real-time GPS location is strictly private telecommunication data accessible only to network operators and emergency services under warrant. OSINTScan only identifies geographic area codes and network prefixes allocated by national regulators.
Privacy, Data Retention & Legal Use
Are my search queries or results stored in a database?▼
No. OSINTScan is built with a zero-retention privacy architecture. Searches are executed entirely in volatile server memory. Once the scan completes and your session terminates, all target inputs and results are purged automatically.
Do I need to create an account or provide personal information to scan?▼
No account, email, or credit card is required to use OSINTScan. You can conduct confidential footprint audits with zero registration.
What constitutes responsible and permissible use of OSINTScan?▼
OSINTScan is intended for personal privacy auditing, self-footprint assessments, authorized security penetration testing, and brand protection. It must not be used for harassment, stalking, unauthorized surveillance, or violating platform terms of service.
