Email, Phone & IPv4 Text Redactor
Replaces valid dotted IPv4 candidates with `[IP]`, email-like strings with `[EMAIL]`, and phone-like strings with `[PHONE]`. It does not identify names or comprehensively remove personal data.
About this email, phone & ipv4 text redactor
Replaces valid dotted IPv4 candidates with `[IP]`, email-like strings with `[EMAIL]`, and phone-like strings with `[PHONE]`. It does not identify names or comprehensively remove personal data Applies Unicode-compliant text transformations and parsing directly in the browser tab without data leakage.
Text processing & transformation mechanics
Executes high-performance regular expression pattern extraction and Personally Identifiable Information (PII) data masking. Pre-compiled ECMAScript regular expressions extract RFC 5322 email addresses, IPv4/IPv6 addresses, RFC 3986 URLs, credit card numbers (validated via Luhn algorithm ISO/IEC 7812), and ISO 8601 dates. Text-comparison tools in this group use their own documented local rules; no common minimal-edit-script algorithm is claimed.
Worked text manipulation example
Scenario: Replace matching contact and IPv4 patterns in one pasted text.
Sample input:
Processing: Replace the valid IPv4 first, then the email-like string, then the phone-like string.
Illustrative output:
Character encoding & string length boundaries
This is local pattern replacement, not comprehensive PII detection. Names, IDs, IPv6, malformed contacts, and unmatched formats can remain; verify before sharing.
Text formatting and transformations in Email, Phone & IPv4 Text Redactor preserve character integrity. Check edge cases such as multi-line inputs and special characters before downstream use.
In-memory text processing boundary
String operations and Unicode manipulations in Email, Phone & IPv4 Text Redactor execute entirely in local browser memory without transmitting input text.
Unicode Consortium & text formatting standards
Unicode Consortium standard annexes (UAX) and character encoding specifications:
- Implementation-specific local replacement order: valid IPv4 → [IP], email-like text → [EMAIL], phone-like text → [PHONE]

Frequently asked questions
Which values can Text Anonymizer replace?+
It first replaces syntactically valid dotted IPv4 addresses with `[IP]`, then email-like addresses with `[EMAIL]`, then matching phone-like number sequences with `[PHONE]`.
Can you show an input and its result?+
`Ada 192.0.2.1 ada@example.com +1 415-555-0100` becomes `Ada [IP] [EMAIL] [PHONE]`.
Does replacement prove that personal data is gone?+
No. This is pattern matching, not identity recognition. Names are not replaced with labels such as `[NAME_1]`; account identifiers, contextual identifiers, malformed contacts, IPv6, and other nonmatching formats can remain.
Does it verify an address, number, or IP online?+
No. It only applies local text replacements. It does not contact a verification service or determine whether a matched value belongs to a real person or service.
