Caracteristici și capacități
A complete reference of every feature in the anonym.legal LibreOffice Extension for Writer, Calc, and Impress.
5 Anonymization Methods
Choose the right method for your use case. Each method can be applied globally or per entity type using per-entity operators.
Replaces PII with typed tokens like <PERSON_1>, <EMAIL_ADDRESS_1>. Consistent within a document — the same name always gets the same token.
Reversible with the replacement mapping.
Replaces characters with asterisks while preserving the format. Useful when you need to show partial data like the last 4 digits of an SSN.
Configurable masking character and visible characters.
Completely removes the PII and replaces it with [REDACTED]. Irreversible — the original data cannot be recovered.
Best for maximum privacy and regulatory compliance.
Produces a cryptographic hash of the PII. The same input always produces the same hash, enabling cross-document correlation without exposing the data.
One-way function. Cannot be reversed.
Encrypts PII with AES-256-GCM authenticated encryption. The ciphertext replaces the original text in the document. With the correct encryption key, you can decrypt and restore the original data.
Best for workflows where authorized users need to deanonymize later. Keys are managed via the Encryption Keys feature.
Predefiniri
Presets save your anonymization configuration so you can reuse it across documents and devices.
Save Configurations
Save entity selections, method, language, and per-entity operator settings as a named preset.
Sincronizare pe dispozitive
Presets sync automatically to your anonym.legal account. Access them on any device where you sign in.
Per-Entity Operators
Configure different operators for each entity type within a preset (e.g., Replace names, Mask SSNs, Hash emails).
Preset Management
Create, rename, and delete presets from the sidebar. The Presets panel shows preset name and entity configuration.
Chei de criptare
Manage encryption keys for the Encrypt anonymization method. Keys are stored securely on the server, wrapped with your account key encryption key (KEK) for zero-knowledge security.
ZK-Wrapped Storage
Keys are encrypted with XChaCha20-Poly1305 using your account KEK before storage. The server never sees your raw encryption keys.
Auto-Load
When you select a saved key from the dropdown, the key value is automatically fetched and decrypted. No manual entry needed.
Session Persistence
Keys persist for the duration of your session. No need to re-select after each anonymization. Cleared on sign-out.
Preview Dialog
The preview dialog opens after analysis and lets you review and customize the anonymization before applying it to your document.
Entity Table
Displays up to 50 detected entities with their type, original text, and proposed anonymization result.
Select / Deselect
Use Select All or Deselect All buttons, or toggle individual entities. Only selected entities will be anonymized.
Per-Entity Review
Review each detected entity individually. Accept or reject specific detections to handle false positives.
Format Preservation (Writer Only)
When anonymizing in Writer, the extension preserves the original text formatting. The replacement text inherits the same visual style as the original.
Font Properties Preserved
Nume font, dimensiune font, bold, italic, culoare font, subliniere, tăiere
Paragraph Properties Preserved
Aliniere, indent prima linie, margine stânga, margine dreapta
Note: Format preservation is only available in Writer. Calc and Impress process plain text content without formatting.
Document Support
The extension works across three LibreOffice applications, each with application-specific document handling.
Writer
Full text extraction with selection support. Format preservation for bold, italic, underline, font name, font size, color, and highlight. Processes paragraphs individually.
Calc
Processes cell contents as tab-separated text. Analyzes and anonymizes text within individual cells across sheets.
Impress
Extracts text from slide text objects (shapes). Processes text content from all slides in the presentation.
Multi-Language Detection
The extension detects PII in 48 languages. Set the detection language in the sidebar or switch it from the preview dialog. The language determines which NER models and regex patterns are applied.
Quick Actions
The extension registers toolbar commands for quick access to common operations.
Open Sidebar
Opens the anonym.legal sidebar panel. Available from the toolbar or View → Sidebar menu.
Anonymize Selection
Analyzes and anonymizes the currently selected text. Skips the sidebar and goes directly to the preview dialog.
Analyze Selection
Analyzes the current selection for PII without anonymizing. Opens the preview dialog in review-only mode.
Chunked Processing
Large documents are processed in manageable chunks to ensure reliable results and avoid timeouts.
Chunk Size
8,000 characters per chunk with 400-character overlap to prevent entity splitting at boundaries.
Size Limit
Maximum document size of 10 MB. Documents exceeding this limit should be split or processed by section.
Request Timeout
120-second timeout per API request. Large chunks may require multiple requests.
Sincronizare pe dispozitive
Your configuration syncs automatically across all devices where you sign in with your anonym.legal account.
Predefiniri
Entity selections, methods, operators
Custom Entities
Custom regex patterns and deny lists

Sync runs automatically every 5 minutes. Changes are cached locally and synced when connectivity is restored.
