PII (Personally Identifiable Information) is the correct standard term.
Renamed all instances — comments, UI labels, variable names, function
names (autoDetectPPI → autoDetectPII, scanInputForPPI → scanInputForPII,
ppiWarnings → piiWarnings), CSS comments, README, and options page.
Added Ko-fi donation section to README and Options footer. Tone: no
obligation, no warranty, no influence on updates — just appreciation.

Users can now define custom regex patterns for proprietary token formats,
internal URLs with keys, or any secret the built-in scanner doesn't cover.
Patterns are added/toggled/removed from the Options page and apply to both
the live interception (content.js) and the Test tab (popup.js).
Renamed all user-facing "Secret scanning" labels to "Auto Redact" across
popup and options. Internal variable names (secretScanning, SecretScanner)
kept for backwards compatibility with stored settings.
https://claude.ai/code/session_01KF4i7Ra7zCEDskxDBaNtcT
'Secret Scanner' described what it looks for. 'Auto-redact' describes
what it does — clearer for users. Renamed in popup, options page,
org section, and README. Internal code (secret-scanner.js) unchanged
to avoid breaking references.

Accept (+) button:
- Was reading raw storage (getStorageData) which returns encrypted
blobs when encryption is enabled, silently failing to add mappings
- Fixed: adds directly to the local mappings array and persists via
setStorageData (storage bridge handles encryption transparently)
Auto-detect false positives:
- Was only checking identity values, not explicit mappings — values
already in the mappings table still got flagged as unconfigured PPI
- Fixed: now adds all mapping real/substitute values to the skip set
Ignore button:
- Changed from plain text link to grey pill button for better UX
- Still persists permanently via ss_ignored_ppi in storage
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
When at-rest encryption is enabled, storage.local contains encrypted
blobs. The injector reads raw storage (content script world, no
access to IndexedDB CryptoKey) and sees { _ssLocalEncrypted: true }.
It passed empty config to content.js → no mappings → no substitution.
This is why Firefox stopped working after encryption was enabled.
Chrome/Brave worked because the user hadn't set up encryption there.
Fixed: injector now detects encrypted data and asks the background
script for decrypted config via 'get:decrypted-config' message.
The background uses the Storage module (which has IndexedDB access)
to decrypt and return the data. Falls back to empty config if the
vault is actually locked.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
The early hook approach (inline script, then external early-hook.js)
kept breaking Firefox due to CSP restrictions and timing issues with
the async external script load. Each fix for ChatGPT introduced a
new regression for Firefox/Brave.
Reverted to the original simple approach:
- Injector reads storage, injects content.js via <script src="...">
- content.js captures window.fetch at load time and patches it
- No inline scripts, no early hooks, no __ssOriginalFetch globals
This is what worked on Claude.ai across all browsers before the
ChatGPT fix attempts. ChatGPT support may need a different approach
later (possibly using declarativeNetRequest for header-only changes,
or a ChatGPT-specific content script), but it should not break the
core functionality on Claude.ai.
Kept the Request object handling in the fetch interceptor (needed for
some frameworks) but removed all early hook dependencies.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
The inline <script> with textContent was blocked by claude.ai's
Content Security Policy on Firefox (Chrome is more permissive).
No fetch interception = no substitution = completely broken on FF.
Fixed by moving the early fetch hook to its own file (early-hook.js)
loaded via <script src="..."> which is CSP-compliant. Added to
web_accessible_resources in both Chrome and Firefox manifests.
Also fixed duplicate 'const api' declaration in injector.js that
would have crashed the content script.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Bug 1 - Reveal mode not working (all browsers):
sessionSubstitutions stored "ademo demo" (full name) as key, but
buildRevealPairs looked up "ademo" and "demo" individually. No match,
no reveal pairs, reveal did nothing. Fixed by also storing individual
words from multi-word replacements so both "ademo demo" AND "ademo"
AND "demo" are in the map.
Bug 2 - Missing await on _handleDecryptedMeta (sync.js):
Two call sites returned the Promise instead of the resolved value.
Downstream code checking decResult.data got undefined. Added await.
Bug 3 - Profile selector broken by safeHTML (popup.js):
DOMParser.parseFromString wraps content in <html><body> which
mangles <option> elements when moved to a <select>. Replaced with
new Option() DOM API which creates proper option elements.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Root cause: when importing an encrypted sync code from another device,
_decryptFromSync was replacing the local encryption config (salt) with
the source device's salt. This caused:
1. Local key cache derived from wrong salt
2. Local data (encrypted with local salt) became unreadable
3. _applyData tried to write with the wrong key
Fixed with a complete refactor of cross-device decryption:
- authenticateForSync() derives a TEMPORARY key using the source salt
- Temporary key stored separately as 'tempSyncKey' in IndexedDB
- Local encryption config and cached key are NEVER modified
- After decryption, _applyData writes via _writeSecure using the
LOCAL key (which uses the local salt)
- _handleDecryptedMeta extracted for code reuse
Also:
- Options.js auth handler detects pending sync import and routes to
authenticateForSync instead of regular authenticate
- After auth success, automatically retries the import
- README updated: imported passwords are protected (dots in UI,
vault password to reveal, AES-256 encrypted at rest)
- Bumped to v2.0.9
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Sync operations (browser sync, Gist, custom URL, sync code) now refuse to
operate without encryption enabled. Disabling encryption also turns off all
active sync channels. Activity log cap reduced from 200 to 100 entries for
both storage and display.
https://claude.ai/code/session_01KF4i7Ra7zCEDskxDBaNtcT
ChatGPT (and potentially other AI services) calls fetch() with a
Request object as the first argument: fetch(new Request(url, opts))
instead of fetch(url, opts). The interceptor only handled the second
form, so ChatGPT's conversation requests passed through unmodified.
Fixed by handling both fetch signatures:
- fetch(url, options) — existing path
- fetch(Request) — new: extracts URL, method, headers, reads body
via request.text() for JSON/text content types
Also handles non-string body types:
- Blob → text via blob.text()
- ArrayBuffer → text via TextDecoder
- URLSearchParams → string via toString()
These cover the various ways modern frameworks call fetch().
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Auto-sync now:
- Persists Gist token in the auto-sync config so it survives
page reloads (previously only read from the input field)
- Saves token when the Gist token field changes (not just on toggle)
- Validates that credentials exist before enabling
- Shows current status: method, interval, last push/pull times
- Updated UI description to clarify it works in all browsers
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
_getAllData() was reading raw storage which contains encrypted blobs
when at-rest encryption is enabled. The sync code export would send
{ _ssLocalEncrypted: true, data: <blob> } instead of actual identity
data. The importing browser couldn't use these blobs.
Fixed _getAllData() to use Storage._readSecure() which decrypts
transparently. Fixed _applyData() to use Storage._writeSecure()
so imported data gets encrypted on the receiving end.
Also: hide the Auto-Sync Folder section entirely in browsers that
don't support File System Access API (Firefox, Brave, Safari)
instead of showing a broken-looking error message.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Set Chrome, Firefox, and package.json all to version 2.0.0
(major bump reflecting encrypted storage, document scanning,
org/team features, sync improvements).
Sign script rewritten:
- Tries current version first instead of always bumping
- Only bumps on "version already exists" errors
- Handles rate limiting by parsing throttle duration from error
and waiting the exact time (not blindly retrying)
- Only updates source files on successful signing (not before)
- Reduced max attempts to 5 (with proper backoff, shouldn't need more)
- Commits version bump only after successful sign
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Passwords imported from password managers are now:
- Displayed as dots (••••••••) by default in both options and popup
- Separated into their own "Passwords" section in options page
- Only revealable by entering the vault encryption password
- Always masked in the popup mappings list (no reveal there)
Options page:
- New Passwords section with locked/unlocked states
- Reveal button validates against vault encryption password
- Hide button re-masks all password values
- Password mappings excluded from the general Mappings table
- Delete and enable/disable controls work while masked
Popup:
- Password-category mappings show dots for real value
- Password category added to mapping add form dropdown
Storage:
- Added 'password' to default categories list
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
New module: import-parser.js
- Auto-detects format from filename and content headers
- Chrome/Firefox password CSV: extracts usernames, emails, domains
(NEVER imports passwords)
- Bitwarden/1Password CSV: extracts usernames, emails, domains
- Browser autofill CSV: extracts names, emails, phones, addresses
- Plain CSV: two-column real→substitute with optional category
- Plain text: one value per line, auto-categorizes (email, phone, name)
- Values without substitutes are marked "needs mapping" so the user
can see what needs filling in
Options UI:
- Import button in Transfer Data section
- Preview panel shows parsed items before applying
- Summary shows counts and highlights items needing substitutes
- Apply merges into active profile (identity) and mappings table
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Re-verification (TTL expired, key still cached) now accepts any ONE of:
- WebAuthn (biometric/PIN)
- TOTP code alone (no password needed)
- Password alone (no TOTP needed)
First-device setup still requires password (+ TOTP if configured) since
the password is needed to derive the encryption key.
Added reverifyWithTOTP() and reverifyWithPassword() to sync.js.
Auth prompt UI adapts: first-device shows password+TOTP fields,
re-verify shows all three methods as alternatives.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
- CryptoKey now persists in IndexedDB forever — never auto-deleted
- TTL controls when re-verification is needed, not key lifetime
- WebAuthn is the primary re-auth method (not a post-expiry fallback)
- Password only needed once per device (first-time setup)
- Added needsReverification() and markVerified() to crypto.js
- Auth prompt adapts message: first-device vs re-verify vs decrypt
- Biometric button hidden on first-device setup (no credential yet)
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Sync encryption:
- AES-256-GCM encryption for all sync channels (browser sync, gist,
custom URL, folder sync, sync codes)
- Password with optional TOTP (RFC 6238) second factor
- Configurable auth TTL: session, 30/90/180/365 days, or never
- CryptoKey cached in IndexedDB — auth only needed when cache expires
AND new data exists (lastModified check runs before auth prompt)
- WebAuthn (biometric/PIN) as low-friction re-authentication gate
- Full options UI for setup, password change, and inline auth prompt
Smart reveal:
- Track which substitute values were actually sent outbound per session
- Reveal mode only replaces values that were genuinely substituted,
preventing false positives (e.g. AI using the word "user" won't be
replaced with a real username that maps to "user")
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
GitHub Gist sync:
- pushToGist(token): pushes all settings to a private Gist; creates a
new Gist on first use and stores the Gist ID in local storage so
subsequent pushes update the same Gist.
- pullFromGist(token): fetches the Gist, compares lastModified, applies
if newer (raw_url used to avoid API truncation).
- No desktop client needed; works across any browser/OS with a GitHub PAT.
- Options page shows a token field + Push/Pull buttons; Gist ID shown
once linked.
Custom URL sync:
- pushToUrl({ url, method, headers }): HTTP PUT to any endpoint.
- pullFromUrl({ url, headers }): HTTP GET, applies if newer.
- Works with Nextcloud/ownCloud WebDAV, self-hosted servers, cloud
functions, or any static-file host that allows PUT.
- Options page shows URL + optional JSON headers field + Push/Pull.
Both methods write ss_sync_notification on apply, triggering the purple
'SYN' badge and desktop notification added in the previous commit.
https://claude.ai/code/session_01TKpSR9M8JgHLXCp5CeDsQP
Notification system:
- When sync applies data (file folder, browser account, or sync code),
ss_sync_notification is written to local storage with the source.
- Service worker catches it via storage.onChanged, shows a purple 'SYN'
badge on the extension icon that persists until Options is opened, and
fires a desktop notification ('Settings updated via sync folder — open
Options to review').
- Clicking the desktop notification opens the Options page directly.
- On service worker wake, SYN badge is restored if the notification was
not yet dismissed.
- Opening Options clears ss_sync_notification, resets the badge, and
sends a sync:notification-seen message to the service worker.
- Added 'notifications' permission to both manifests.
Cloud storage clarity:
- Options page now explicitly lists that the folder sync works with any
cloud storage that has a desktop sync client: Dropbox, OneDrive, Google
Drive, iCloud Drive, Box, pCloud, Nextcloud, Synology Drive, etc.
https://claude.ai/code/session_01TKpSR9M8JgHLXCp5CeDsQP
PPI + button fix:
- After adding a mapping, the real PPI value is now immediately replaced
with the fake value in the input/contenteditable element via the new
replaceInInput() helper (handles both <textarea>/<input> and
contenteditable divs by walking text nodes).
- Triggers a re-scan 150ms later so the pre-send warning updates or
dismisses itself if no more PPI remains.
Auto-sync folder (File System Access API):
- User picks a folder once per browser via "Choose Sync Folder".
Any settings/mappings/identity change writes silent-send-sync.json
to that folder automatically (via api.storage.onChanged listener).
- On options page open and every time the page regains focus, the file
is read back; if its lastModified is newer than local data, settings
are imported immediately and the UI refreshes.
- File handle is stored in IndexedDB (ss_sync_handles) so it persists
across browser sessions without repeated permission prompts.
- Pick the SAME folder in each browser (or a synced cloud folder for
cross-computer sync) — fully automatic after that, no copy-paste.
- sync.js gains saveSyncDirHandle / loadSyncDirHandle / clearSyncDirHandle
helpers backed by IndexedDB.
https://claude.ai/code/session_01TKpSR9M8JgHLXCp5CeDsQP
Bug fixes:
- Date (possible DOB) pattern now requires context words (born, birthday,
dob, etc.) before firing — prevents spurious warnings on page-load API
calls that happen to contain ISO dates in conversation history.
- Highlight regex now uses word boundaries (\b) so short substitute values
(e.g. "aud") no longer match inside unrelated words like "Claude".
- Both TreeWalkers in content.js now skip the extension's own UI elements
(.ss-autodetect-warning, .ss-presend-warning, .ss-reveal-badge) to
prevent the highlight API from marking text in the extension's banners.
Settings sync:
- New src/lib/sync.js: exportSyncCode / importSyncCode (base64 JSON) for
manual copy-paste across any browser combination. Newest lastModified
timestamp wins; force flag available to override.
- browser.storage.sync support: when "Browser account sync" is enabled the
extension automatically pushes/pulls via Firefox Sync or Chrome account,
chunked to stay within per-item quota limits.
- storage.js now writes ss_lastModified on every save so conflict resolution
has an accurate timestamp.
- service-worker.js listens for both local and sync storage changes to keep
all copies in sync.
- New "Sync Between Browsers" section in options.html with Generate/Copy/
Import Sync Code UI and the browser sync toggle.
https://claude.ai/code/session_01TKpSR9M8JgHLXCp5CeDsQP
Detected PPI is now auto-redacted in the fetch hook using
RFC/standard reserved values — not just warned about:
- IPs → 192.0.2.1 (RFC 5737 TEST-NET-1, never routed)
- MACs → 00:00:00:00:00:00
- Addresses → 123 Example Street, Anytown, ST 00000
- GPS → 0.000000,0.000000 (Gulf of Guinea)
- Dates → 01/01/1970 (Unix epoch)
- EINs → 00-0000000 (impossible prefix)
- Paths → /home/user
- Git → example org
These are obviously fake and guaranteed not to be real data,
unlike random values which could be confused with actual PPI.
New Options toggle: "Auto-redact detected PPI on send" (on by
default). When on, PPI is caught in the fetch hook even if the
user hits Enter immediately after pasting. Warning banner now
says "Auto-redacted with standard placeholders" instead of
"These were sent as-is."
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Like spellcheck for privacy. Scans text as you type and paste
into chat inputs (debounced 800ms). Shows a dark floating warning
panel listing detected PPI BEFORE you hit Enter.
Each detected item has a green [+] button that instantly:
1. Generates a plausible fake value (random IP, fake address, etc.)
2. Adds it as a mapping to storage
3. Shows a checkmark to confirm
The warning disappears when you clear the text or when all
detected items have been addressed.
Three new Options toggles:
- Auto-detect unconfigured PPI (on by default)
- Offer to auto-add detected PPI (on by default)
Also adds a storage bridge (postMessage) so the page-world
content script can read/write chrome.storage through the
injector.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Scans outbound messages AFTER all substitutions for personal data
the user forgot to configure:
- Private/public IP addresses (skips 127.0.0.1, 8.8.8.8, etc.)
- MAC addresses
- Street addresses ("123 Main St")
- GPS coordinates
- Dates (possible DOBs)
- EIN/tax IDs
- Home directory paths not caught by smart patterns
- Shell prompts (user@host)
- Git remotes (reveals username/org)
- Environment variable assignments (HOME=, USER=, etc.)
Shows a floating dark warning banner (top-right, auto-dismisses
after 15s) listing each detected item with its type, value, and
hint. Skips values already in the user's identity config.
Also shows PPI warnings in the popup Test tab and adds toggle
in Options to disable auto-detect.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
License: Changed from MIT to BSL 1.1. Free for personal use,
commercial use requires a paid license. Auto-converts to MIT
on March 26, 2030.
Export/Import: Options page now has "Transfer Data" section:
- Export All (plain) — JSON file with all identities, mappings, settings
- Export Encrypted — AES-256-GCM with PBKDF2 password derivation,
saved as .ssbackup file
- Import — handles both plain and encrypted backups, prompts for
password if encrypted
Crypto uses Web Crypto API (browser-native, no dependencies):
100k PBKDF2 iterations, random salt + IV per export.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Storage issue: Chromium/Brave keeps storage.local data even when
an unpacked extension is removed and reloaded. Added "Reset
Everything" button in Options → Danger Zone that clears all data
(double-confirm to prevent accidents).
Reveal mode: Now re-runs revealAllResponses() every 2 seconds
while active to catch streamed content and dynamically loaded
responses. Adds console logging for reveal toggle state changes
to aid debugging. Cleans up interval when reveal mode is turned off.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Identity fields now support multiple entries per type:
- Add unlimited names (first, last, middle, nickname), emails,
usernames, hostnames, and phone numbers per profile
- "+ Add" button on each section, "x" to remove rows
- Names have a type selector (1st/Last/Mid/Nick)
README now includes:
- First-time setup walkthrough (step by step)
- Icon color legend (gray/black/blue/red)
- Keyboard shortcuts table
- Note that extension does nothing until configured
Also bumps version to 0.3.0 for Firefox re-signing.
