Frequently asked questions

Sky Matrix is a flight-briefing assistant for pilots. It reads your Operational Flight Plan (OFP) and turns it into a clear inflight companion: weather and NOTAMs, an inflight display with timers and reminders, crew-rest planning, dangerous-goods reference and announcement help. It is for reference and individual use only, not for operational use, the official hard-copy OFP always governs the flight.

Every device can start one free trial directly from the app's welcome screen, no payment details needed. Tap Start Trial, confirm your email, and your access code is issued to that device. The trial runs once per device; when it ends you can subscribe to keep using the app.

Open skymatrix.biz/app.html in Safari (iPad/iPhone) or Chrome (Android), then use Share → Add to Home Screen. It installs as a full-screen app and works offline after the first load. Android users can alternatively install the signed APK from the Download section of the home page.

One subscription covers two devices — typically an iPad and a phone. Each access code is cryptographically bound to the device that generated its Device ID, using a signature only our server can produce, so request a code on each device using the same email. Adding a third device retires the oldest. To move your setup across, use Load → Back up & move your setup → Save to my account on the first device and Load onto this device on the second. If you replace a device, contact admin@skymatrix.biz to move your licence.

After you activate the app you set a PIN once. From then on, each time you open the app you unlock it with that PIN, or with Face ID / fingerprint if you enabled biometric unlock. You are never asked to re-enter your licence code, and app updates never re-prompt for it.

On the login screen choose Forgot PIN. Because your licence is still valid on the device, you can reset the PIN and set a new one without buying a new code. If you cleared the app's data entirely, you may need to re-activate with your existing access code.

You'll see a reminder popup starting 7 days before expiry. When it lapses, the app shows a "get a new code" screen and returns to the welcome flow so you can subscribe or renew. Your typed flight data stays on the device.

Updates: no. The app updates itself automatically, you simply get the latest version next time you open it, and your access code and PIN are never re-requested. Reinstalling on Android: also no, your licence is tied to a stable device identity that survives uninstall and reinstall, so the same code keeps working. On iPhone/iPad, clearing Safari's website data can reset the device identity; if that happens, email admin@skymatrix.biz and we'll re-issue your code for the new Device ID at no charge.

You don't have to do anything, feature and fix updates arrive automatically the next time you open Sky Matrix (it always loads the latest version). The only exception is a new Android APK shell: because it's installed outside the Play Store, occasional shell updates (rare) are announced on our changelog and you install the new APK manually.

On the Load screen, drop in (or choose) your OFP as a PDF or text file, the app extracts the text and fills the briefing automatically. You can also tap Read with AI (beta) to have our OFP reader parse less-common layouts. If a field looks uncertain it is flagged for you to check rather than shown silently.

Yes. Once loaded, the app runs offline: timers, rest planning, the inflight display, your saved OFP and every value you have typed all work with no connection.

Reading a new flight plan depends on your plan. With a subscription, the offline reader is delivered to your device automatically the first time you connect after subscribing; after that a plan can be read with no internet at all. On a trial, plans are read by Sky Matrix AI, which needs a connection.

Features that fetch live data — aircraft lookup, live weather and NOTAM refresh, translating an announcement for the first time, and reading a photograph — need internet on either plan.

Aircraft lookup uses the official Flightradar24 data service for type and route. Live weather and NOTAMs are pulled from public aviation sources; if a live source is unavailable, the app falls back to the weather already contained in your OFP. As with all data in the app, treat it as reference, verify against official sources.

PA holds twenty-one standard announcements — greetings, abnormal and emergency — alongside any you save yourself. The flight's own details, and your name and rank from your profile, fill in automatically; anything the app cannot know, such as the destination weather or a holding fix, is left as a highlighted gap you tap and type straight into.

You can also write, paste or photograph your own announcement and have Sky Matrix AI tidy the wording and mark the parts that change from flight to flight. It transcribes what is there; it does not invent wording.

Any announcement can be translated into another language, written either in that language's own script or in English letters, and the translation is kept on the device for use in flight. It is a machine translation: have a fluent speaker check it before using it on board, and the English remains the approved wording. Always review before use.

7-day money-back guarantee, no questions asked. If Sky Matrix isn't for you, email admin@skymatrix.biz within 7 days of purchase and we'll refund you. Checkout and taxes are handled by Lemon Squeezy as merchant of record. When a refund is processed, the licence on that device is automatically revoked.

Yes, monthly, 6-month and yearly plans renew automatically at the end of each period so your access is uninterrupted. You can cancel any time before the next renewal from the billing link in your purchase receipt; access continues until the paid period ends.

Your flight data and settings stay on your device. We only process the minimum needed for licensing (your Device ID and email) and, when you use them, for AI OFP reading / announcements. Full details are on the Privacy & Security page.
