Tap a dish to add its calories. Numbers are estimates per serving.
This Post-it looks like a diet calorie calculator. Choose a secret number (your "daily goal"). Later, typing that exact number into the goal field is the only way back to the document editor. It is shown once and kept only in memory.
Tip: pick a believable calorie goal you will remember (for example 1850). If you forget it, you cannot return to the editor in this session.
HTML keeps formatting and images; TXT/MD are plain text.
JS, CSS, JSON, XML, CSV, and SVG save the current text as a plain-text file with that extension (the content is your document text, not converted).
Generates meaningless characters/symbols/Unicode to overwrite content (1–100 pages).
Hashes the current document text (or a dropped/selected file). Paste an expected value to compare.
Reads the code as text and flags suspicious lines. It never runs the code. Click a finding to jump to that line.
Sentinel Mode keeps protection running only while you explicitly turn it on. Each switch below works independently and only where this browser and environment allow it. Nothing scans in the background on its own.
Overwrites the content in memory with random data, then derives a throwaway key 100,000+ times (PBKDF2) and discards it, then clears the editor. This protects what is in this editor; it does not physically erase your disk.
How to open a private window:
Sends the current document to a nearby device with no internet. Bluetooth carries any size; ultrasound (sound) carries only short messages. The recommendation below is based on your document size.
A warm-paper offline document editor plus local source review, hash verification, static risk scan, and explicit offline transfer tools. Received code is never executed automatically.
Paste a VG code or imported package. The content is shown as text first, then you can hash, scan, insert, or discard it.
Create or join a consent-based group. Relay is off unless you explicitly allow it.
Uses the microphone only after you press Start. It estimates sudden loud sound candidates locally; it does not record or upload audio.
SOS is not active until you set a group/recipient. Hold the SOS button for 3 seconds to send. Release early to cancel.
Share this emergency code with approved people. If ultrasound is available, a tiny SOS tone was attempted. Location may arrive as an update if permission succeeds.
Keep holding for 3 seconds. Release before the bar fills to cancel.
Clears the current document, inbox/outbox, transfer buffers, microphone references, and local working state. A 4-digit PIN prevents accidental use. This is not guaranteed forensic deletion.
Choose what to send. Vitalguard-AI calculates size, ultrasound time, and safer offline fallbacks before anything leaves the device.
A memory-only list of packages created or received in this session. Save a .vgpack if you need to carry something outside this page.
A no-library visual fallback for short packages. It is not a full QR standard; keep the manual code as backup.
Use short transparent humanitarian codes for slow ultrasound. The codebook is public and built into this HTML.
AURA estimates the noise around you and picks the error-correction strength automatically. It starts light and gets stronger only if a message fails. Every decision is shown below. It learns on this device only and sends nothing.
Open, read, search, snapshot, and compare source locally. Snapshots live only in memory and disappear when the page is closed.
