First Launch
When you open anonym.plus for the first time, a guided setup wizard walks you through five steps: choosing how to start, creating your secure vault, setting a PIN, activating your license, and selecting an output folder. Each step is explained below with screenshots.
Step 1: Welcome Screen
The welcome screen presents three options to get started:
Welcome screen — choose how to get started
| Option | Description |
|---|
| Try Demo | Start a 30-minute demo session with text anonymization. No account needed — great for a quick test drive. |
| Get Free Account | Opens registration in your browser, then returns to set up your secure vault. |
| I have an account | Set up your vault and activate an existing license. |
A language selector at the bottom lets you switch the UI language before proceeding. 48 languages are available.
Step 2: Recovery Phrase & Vault Creation
After choosing "Get Free Account" or "I have an account," the app generates a secure vault protected by a 24-word BIP39 recovery phrase. This phrase is the master key to your vault.
Your 24-word recovery phrase — write it down and store safely
Critical: Write down all 24 words in order. This is the only way to recover your vault if you forget your PIN. The app cannot recover it for you.
You can Copy the phrase to clipboard (auto-cleared after 30 seconds) or Save as TXT to a file. Click Hide to blur the words for privacy. You must check "I have safely stored my recovery phrase" before continuing.
Verify Your Phrase
To confirm you saved the phrase correctly, the app asks you to enter 3 randomly selected words by their position number.
Verify 3 random words from your recovery phrase
Type the correct words and click Confirm. If any word is wrong, you'll be prompted to try again. Once verified, the vault is created and you proceed to PIN setup.
Step 3: PIN Setup
After vault creation, you can set a 4–8 digit PIN for quick daily access. The PIN lets you unlock the app without typing all 24 words each time.
Set a PIN for quick daily unlock
- Quick unlock without typing your full 24-word recovery phrase
- Your recovery phrase remains stored securely in the vault
- You can always use the recovery phrase if you forget your PIN
Enter your PIN in both fields and click Set PIN & Continue. You can also click Skip for now to set a PIN later in Settings → Security.
Step 4: License Activation
With your vault ready, the final security step is activating your anonym.plus license to unlock all features.
Sign in with your anonym.plus account to activate
Enter your email and password, then click Sign In & Activate. Your password is hashed locally and never sent to the server in plain text.
Manual Activation
If sign-in doesn't work (e.g., behind a corporate firewall), expand Manual activation (paste or import file) for alternative methods:
Manual activation — paste a license key or import a license file
- Paste license key — paste the JSON license key from your account page
- Import File — import a
.json license file downloaded from your account
You can also click Skip for now to activate later via Settings → Account.
Step 5: Output Folder
The last step lets you choose where anonymized documents will be saved.
Choose where to save anonymized documents
The default folder is Documents/CloakBusiness. Click Browse... to select a different location. You can change this later in Settings → Preferences.
Click Finish Setup to complete the wizard and enter the main application.
Setup complete! You're now ready to anonymize documents. The main interface will load with the file dropzone ready for your first document.

6
Save
Click 'Save as New File' or 'Replace Original' to complete
Step-by-Step: Text Anonymization with Replace
Anonymize text by replacing personal data with type labels like <PERSON> and <EMAIL_ADDRESS>. The original values are permanently removed.
1
Paste Text with Personal Data
Enter or paste a document containing personal information — names, email addresses, phone numbers, physical addresses, Social Security Numbers, credit card numbers, IBANs, and organization names.
2
Select Detection Preset
Choose “General PII Detection” from the preset dropdown. This preset detects Person, Email Address, Phone Number, Location, Date Time, and 7 additional entity types using the English NER model.
3
Analyze Text
Click “Analyze Only” to run the Named Entity Recognition pipeline. A loading spinner shows while the text is scanned for PII.
4
Review Detected Entities
All 10 detected entities appear as color-coded badges: Person (2), Organization (2), US SSN (1), Credit Card (1), Email Address (1), Phone Number (1), Location (1), IBAN Code (1). Toggle individual entities on or off with checkboxes, or use Select All / Deselect All.
5
Configure Replace Operators
The Configure Operators panel shows “Replace” selected for each entity type. Each PII value will be substituted with its type label in angle brackets — e.g., <PERSON>, <EMAIL_ADDRESS>. Quick-action buttons (All Replace, All Redact, All Mask, All Hash, All Encrypt) allow switching all operators at once.
6
Anonymize
Click “Anonymize with Selected Operators” to process. A brief loading state appears while each entity is replaced.
7
View Anonymized Result
The anonymized text appears with all PII replaced: <PERSON> for names, <ORGANIZATION> for company names, <US_SSN>, <CREDIT_CARD>, <EMAIL_ADDRESS>, <PHONE_NUMBER>, <LOCATION>, <IBAN_CODE>. Use Copy to Clipboard or Clear to reset.
Step-by-Step: Text Anonymization with Encrypt
Anonymize text using reversible encryption — each PII value is encrypted with your key and can be decrypted later via the Deanonymize feature.
1
Paste Text with Personal Data
Enter or paste a document containing personal information — same as the replace workflow.
2
Select Detection Preset
Choose “General PII Detection” to detect a broad range of entity types.
3
Analyze Text
Run the NER pipeline to detect all personal data entities.
4
Review Detected Entities
Review 10 detected entities with color-coded badges. Same entity types as replace.
5
Select All Encrypt with Encryption Key
Click “All Encrypt” to set every entity type to the encrypt operator. Select “Production Key (256-bit)” from the key dropdown. Unlike Replace, the encrypt operator produces reversible tokens that can be decrypted later.
6
Encrypt
Click “Anonymize with Selected Operators” to encrypt all PII with the selected key.
7
View Encrypted Result
The output contains reversible encrypted tokens: <PERSON_ENC:a1b2c3...>, <EMAIL_ADDRESS_ENC:...>, etc. These tokens can be decrypted back to the original PII using the Deanonymize feature with the same encryption key.
Reversible: Encrypted tokens can be decrypted back to original values using the
Deanonymize feature. Replace tokens are permanent and cannot be reversed.
Step-by-Step: File Anonymization with Replace
Drop a document file to anonymize — text is extracted, PII detected, and a new anonymized file is saved to your output folder.

Known Limitations
| Issue | Detail |
|---|
| Photos of screens | Moiré patterns, glare, and reflections degrade OCR. Use screenshots instead. |
| Handwritten text | Tesseract is optimized for printed/typed text only. |
| Low resolution | Below 150 DPI may have poor accuracy. Use 300+ DPI for scans. |
| Rotated/skewed text | Text at angles >15° may not extract correctly. |
| Complex backgrounds | Watermarks and colored backgrounds can interfere. |
| Very small text | Below ~8pt at the image's effective resolution may not be detected. |
| Multi-column layouts | OCR may mix columns in complex layouts. |
| NER language | Named entity recognition uses the English model. Pattern-based entities (phones, IBANs, emails) work in all languages. |
Tips
- Use screenshots instead of camera photos of screens for much better results
- Select the correct OCR language matching the text in your image
- Ensure images are well-lit with good contrast between text and background
- For scanned documents, use 300 DPI or higher resolution
- Crop images to focus on the text area for faster processing
- EXIF orientation is applied automatically — no need to manually rotate photos
Batch Processing

Limits
| Parameter | Limit |
|---|
| Files per batch | 20 |
| Total batch size | Combined file size limits apply per format (see Document Anonymization) |
| Parallel processing | Files analyzed concurrently for speed |
Progress Tracking
During batch processing, each file shows its own progress indicator with status (queued, extracting, analyzing, complete). Files that fail are flagged individually without stopping the rest of the batch.
Tip: For large batches, ensure you have sufficient disk space before starting.
Deanonymization (Decrypt)
Restore original PII values from anonymized documents using your encryption keys. Works with any document that was anonymized using the 'encrypt' operator.
Deanonymize mode — File Drop, Text Input, and From History tabs
Input Modes
A
File Drop
Drop an anonymized document (PDF, DOCX, TXT, CSV, JSON, XML, XLSX). Text is extracted and automatically matched against your history to load the correct encryption keys.
B
Text Input
Paste anonymized text directly. The app automatically searches your history for matching encrypted chunks and loads the correct keys — even if the surrounding text was edited.
C
From History
Select a previous anonymization entry. All entity positions and key mappings are loaded instantly.
Step-by-Step: Deanonymize from History
Restore original PII from a previously encrypted anonymization by selecting it from your processing history.
1
Open Deanonymize Panel
Click “Deanonymize” in the header bar. The panel shows three tabs: File Drop, Text Input, and From History. The File Drop tab is active by default with a dropzone for anonymized files. “How Deanonymization Works” info box explains the process.
2

Switch to the “From History” tab. Previously anonymized files are listed with metadata: filename (business-letter.txt), format (TEXT), entity count (10), preset (General PII Detection), and a key icon indicating encryption was used. Click to select.
3
Review Encrypted Text and Select Key
The encrypted text is pre-loaded in the Text Input tab with tokens like <PERSON_ENC:a1b2c3d4e5f6> and <ORGANIZATION_ENC:f7g8h9i0j1k2>. The encryption key selector shows 2 keys available. A green “History entry matched” banner confirms 10 encrypted entities loaded.
4
Decrypt
Click “Deanonymize” to process each encrypted token. A loading state appears during decryption.
5
View Restored Original Text
“Deanonymization Complete” card shows “10 items restored, 0 tokens used”. The fully decrypted text displays all original PII: John Smith, Acme Corporation, 123-45-6789, 4111-1111-1111-1111, john.smith@acme.com, +1 (555) 123-4567, 742 Evergreen Terrace Springfield IL 62704, and IBAN DE89 3704 0044 0532 0130 00. Copy and Download buttons available.
Step-by-Step: Deanonymize via File Drop
Drop an encrypted file to automatically extract text, match against your history, and decrypt all PII.
1
Open File Drop Tab
The Deanonymize panel shows the File Drop tab with a dropzone accepting anonymized documents (PDF, DOCX, TXT, CSV, JSON, XML, XLSX, XLS up to 50MB). “How Deanonymization Works” info box visible below.
2

Click “Deanonymize” to decrypt all encrypted tokens using the matched encryption key.
6
View Restored Original Text
File deanonymization complete — all original PII values restored including names, SSN, credit card, email, phone, address, and IBAN. Copy and Download buttons available.
How to Deanonymize
- Switch to 'Deanonymize' mode using the toggle in the header
- Drop a file, paste text, or select from history — keys load automatically
- If auto-match fails, manually select the encryption key
- Click 'Deanonymize' to restore original values
- Copy or download the restored text
Encrypt → Share → Edit → Decrypt
You can encrypt a document, share it with collaborators, receive it back with edits, and still decrypt the PII:
1
Anonymize a document using the 'encrypt' operator with your encryption key
2
Share the anonymized document (email, cloud storage, etc.)
3
Collaborators edit the document — adding text, rewriting around encrypted chunks
4
You receive the modified document back
5
Drop it in Deanonymize → File Drop — the app auto-detects encrypted chunks
6
Click Deanonymize — all intact encrypted chunks are decrypted
Note: Encrypted chunks must remain intact — if someone partially edits a ciphertext block, that block cannot be decrypted. Surrounding text can be freely added, removed, or rearranged. Missing chunks are skipped; the rest are still decrypted (partial recovery).

Security
Vault Encryption
Your sensitive data is protected with military-grade encryption.
- AES-256-GCM encryption for all stored data
- Argon2id key derivation (64 MB memory, 3 iterations)
- BIP39 24-word recovery phrase
- PIN-based quick unlock for daily use
- Sensitive data zeroized from memory when locked
How Your Data is Processed
1
Files are read locally on your computer
2
Text is extracted locally — documents never leave your machine
3
PII detection runs on the local Presidio engine (bundled with the app)
4
Detected entities are anonymized locally via the Rust backend
5
Encryption keys never leave the local vault (zero-knowledge boundary)
6
Document reconstructed in original format (PDF, DOCX, XLSX, etc.)
7
Output saved to your chosen folder
8
Results stored in encrypted vault history for deanonymization
What We Never Store
Zero-knowledge design: We never store your original documents, recovery phrase, encryption keys (stored only in your vault), or document contents (only metadata for history).
Troubleshooting
| Issue | Solution |
|---|
| App shows white screen | Try restarting the app. If persists, reset vault in Settings > Security. |
| Forgot PIN | Use your 24-word recovery phrase to reset the vault. |
| Lost recovery phrase | If vault is unlocked, view it in Settings > Security. Otherwise, data cannot be recovered. |
| Files not processing | Check file size limits. Ensure the correct file format is used. |
| Sign in with Browser not working | Ensure your default browser allows the anonym-plus:// protocol. |
| Presets not loading | Check internet connection. App will use offline fallback presets. |
| Image analysis returns no entities | Verify the correct OCR language is selected. Ensure clear, readable text at 300+ DPI. Use screenshots instead of photos of screens. |
| Image redaction misses some text | OCR may struggle with handwritten text, very small fonts, skewed text, or complex backgrounds. Straighten the image and increase contrast. |
