CC Planner Pro · Version 2.1 · Protection readiness & planning
Know what you have. Know what you need. Go prepared.
A local-first planning tool for airborne-infection precautions. Track your protective supplies, describe the activity ahead, and see the recommendations lined up against what is actually in your closet, your bag, and your car.
Readiness board
Illustrative product preview
The board above uses a fictional inventory to show how the app organizes a plan. It is not a live assessment, and CC Planner does not calculate anyone's chance of infection.
Why this exists
The hard part was never knowing that respirators work.
Most people who take airborne precautions seriously already know the layers: well-fitting respirators, ventilation, filtration, testing, distance. What breaks down is the logistics of a household.
- What do I actually own? The box in the hall closet, the one in the car, and the half-used pack from last winter.
- Where is it? A respirator in the basement is not a respirator you are wearing on the train.
- Is it still usable? Tests expire. Cartridges age out. Filters pass their interval quietly.
- Am I running low? Four left sounds fine until you are using one a day.
- What should I bring today? A clinic visit, a flight, and a school day are not the same packing list.
CC Planner connects those five questions to each other. That is the whole product: the operational layer underneath precautions you have already decided to take.
The loop
Inventory, plan, compare, prepare.
Four steps, in order, and then back around as supplies run down.
Inventory
Add what you own: category, location, quantity, spec, cost, and a purchase link. Say whether each item is consumable, replaced on a schedule, or durable.
Plan
Pick a preset activity or build your own: setting, duration, crowding, ventilation, and whether masking is feasible the whole time.
Compare
The plan's recommended layers land in three columns against your inventory: what you already have, what needs attention, and what to consider adding.
Prepare
Pack the kit, reorder what is low from your own saved links, and set the next replacement date so the same gap does not surprise you twice.
Supplies deplete · alerts return you to step one
What CC Planner Pro does
Specific tools, not a dashboard.
Everything below is in version 2.1 and runs entirely in your browser.
Eight categories, real locations
Respirators, filters, purifiers, tests, monitors, eye protection, sanitizers, and anything else. Search and filter by category or location, with a table on desktop and cards on a phone.
Consumable, timed, durable
Consumables project depletion from a usage rate. Timed items count down from an interval and their last replacement. Expiration dates apply to anything. The soonest date wins.
Urgent, upcoming, planned
Under seven days, under thirty, and everything else, each with the reason: depletion, replacement due, expiring, or out of stock. Sort by soonest, category, location, or replacement cost.
Your links, not ours
Save a purchase link on an item and the alert gets a Reorder button that opens it. No affiliate links, no marketplace, no vendor relationships — the link is whichever one you saved.
Reusable packing lists
Build a kit from items you already track — everyday carry, travel, medical visit — and a plan will suggest the kits that cover what it just recommended.
Seven presets, plus your own
Flight, medical appointment, concert or event, work or school day, family gathering, hotel stay, and public transit. Create, edit, duplicate, and favorite custom scenarios for the situations you plan repeatedly.
Tiered, with reasons attached
Each suggested layer is marked essential, recommended, or optional, and carries a plain sentence explaining why this situation calls for it. Then it is matched against your inventory.
Conditions in, guidance out
Enter ventilation impression, crowding, duration, an optional CO₂ reading, and whether you will be masked. You get a qualitative summary and practical adjustments — never a probability.
eACH with the math shown
Estimate equivalent air changes per hour from purifier CADR, mechanical ventilation, and a natural-ventilation estimate. Every line of the calculation is printed with the result, along with its assumptions.
Evidence, replies, and letters
An evidence library with sources and limitations, conversational responses to claims you may hear, and adaptable letter and speech templates for school and workplace advocacy.
JSON backup, CSV, print
A JSON backup holds your full state; CSV covers inventory. Imports preview and ask before merging or replacing. A printable readiness report summarizes items, what is due, kits, and cost.
Health record and demo data
A local vaccination history you can switch off entirely, and clearly labelled demo items you choose to load, remove at any time, and which are never recreated behind your back.
Privacy
Your planning data never leaves your device.
This is a design constraint, not a setting. CC Planner has nowhere to send your data, because it has no server to send it to.

Where your data lives
Inventory, kits, scenarios, settings, and the optional health record are written to your browser's local storage on this device, in this browser profile. The app makes no network requests for your data at any point, and there is no sign-in.
By default that stored copy is ordinary browser storage, which is not encrypted. Anyone with access to your unlocked device and browser profile can read it.
Optional encryption
You can turn on a passphrase. The app then encrypts your stored state with AES-256-GCM, using a key derived from your passphrase with PBKDF2-SHA-256 at 310,000 iterations, through the browser's own Web Crypto API. If Web Crypto is unavailable, encryption is refused rather than faked — there is no fallback cipher.
The passphrase is never stored and never transmitted, so it cannot be recovered or reset. An auto-lock re-locks the app after inactivity.
Exports are yours to handle
JSON and CSV exports and the printable report are plain files, written wherever your browser saves downloads. They are not encrypted by the app. Once a backup leaves CC Planner, its security is whatever your storage, cloud sync, or email gives it.
What we are not claiming
No software can promise absolute security. Encryption protects a stored copy at rest; it does not protect a device that is compromised, shared while unlocked, or backed up somewhere else. Erasing all local data from the app's settings clears what CC Planner wrote — it cannot reach copies you exported.
Planning aid, not a risk score
It helps you prepare. It does not predict what will happen to you.
This distinction is built into the application, and the marketing page will not blur it.
What CC Planner can do
- Summarize the conditions that generally raise or lower exposure opportunity — ventilation, crowding, duration, and protection.
- Translate those conditions into practical preparation: what to bring, what to check, what to replace.
- Show the reasoning behind each recommended layer, and point to the evidence entry behind it.
- Estimate equivalent air changes per hour from stated inputs, showing every step of the arithmetic.
What it cannot do
- Calculate your probability of infection. It produces no risk percentage, and none should be inferred from it.
- Serve as a validated clinical or epidemiological risk model. It has not been validated as one.
- Replace individualized medical advice from a clinician who knows your history.
- Measure infection with a CO₂ reading — that number describes rebreathed air, not virus.
Evidence
Recommendations that show their work.
The Learn section is not a blog. Each entry in the evidence library follows the same structure, so you can see the shape of the claim before you decide what to do with it.
Recommended layers in a plan link back to these entries, so a suggestion is never just an assertion appearing out of nowhere. Sources carry DOI links where they exist, and there is a one-tap copy for the citations behind an entry.
A future release is expected to link to a canonical evidence library maintained separately; that address is not published yet, so this page does not print one.
- Claim
- The specific statement being made, in one sentence.
- In plain language
- What it means for someone deciding what to do this week.
- Evidence strength
- How well supported the claim is, stated openly rather than implied by confident wording.
- Sources
- Named studies and guidance, with DOI links where available.
- Last reviewed
- When the entry was last checked, so staleness is visible.
- Limitations
- What the evidence does not establish, kept in the entry rather than left out.
Entries carried over from earlier versions whose sources have not been re-verified against the primary literature are labelled Needs evidence review inside the app. They are neither quietly deleted nor dressed up with invented citations.
Local-first installation
Install it, then use it on a plane.
CC Planner Pro is a Progressive Web App. Where your browser supports installation, it can live on your home screen or dock and open without a browser window.
- 01Open it once onlineThe first successful online load caches the app shell and icons on your device. After that, it is designed to open from that cache without a connection, for as long as your browser keeps the cache.
- 02Install where offeredChromium browsers show an install prompt, which the app also exposes as an Install button. In Safari on iOS and iPadOS, use Share, then Add to Home Screen.
- 03Update on your termsWhen online, the app loads current code first. If a new version is waiting, you get a prompt and decide when to switch; you can also check for updates from the About panel.
Installation and offline caching depend on your browser and platform, and are not available in every one. Nothing in the app requires installation — it runs the same in a normal tab. Storage and caching behavior vary across browsers, devices, browser profiles, and installed-app environments, and a browser may clear cached files or stored data on its own. Treat a JSON backup as the way to move your data between them, and as your own copy of it.
