Straight answers

Yes, really. Building, editing, saving, printing and exporting checklists are free forever for personal use, with no caps on how many checklists, sections or items you make. There's no trial and no paywall in the way of the actual work.

The only thing money changes is branding on the printed page: supporters get their tail number, a logo, and watermark-free prints. That's the whole catch.

No — you can start building immediately, and it saves in your browser. Signing in (also free) keeps your checklists safe across devices and lets you share them. On an iPhone or iPad especially, browser storage can be cleared without warning, so an account is the safe way to not lose your work.

Your checklists are private by default. Nothing is public unless you explicitly create a share link for it. You can export a full copy of your data, and you can delete your account and its checklists whenever you want. There are no ads, and your data is never sold. See the privacy page for the details.

This isn't legal advice, and these checklists are not authoritative documents. Here's the honest version: 14 CFR 91.9(b) requires that the current, approved Airplane Flight Manual or POH (or the approved manual material, markings and placards) be available in the aircraft on each flight. A checklist you build here is a memory aid derived from that approved material — not a replacement for it.

The safe practice, and the one I recommend, is simple: keep the approved POH/AFM in the aircraft as the regulations require, and treat any homemade checklist — ours included — as something you built from it, always cross-checked against it. If you want certainty about your specific situation, talk to a CFI or the FAA.

Supporting keeps the lights on — hosting, the domain, and the email that sends your sign-in links — and it helps fund the IFR training behind this project. As a thank-you, any donation unlocks branding (tail number, logo, watermark-free prints) for 12 months; Pro is the same thing as an auto-renewing yearly subscription so it never lapses. You're paying to say thanks and to brand your prints, never to unlock core features. See pricing.

When you share a checklist, the app mints a long, random, unlisted link — it isn't indexed by search engines and can't be guessed or enumerated. Anyone with the link sees a clean, read-only copy and can "fork" it to make their own editable version. You can unshare at any time, which kills the old link; sharing again makes a fresh one. Forks are independent copies and aren't affected.

Yes. Individuals can just use the free tier or donate to unlock branding. For a school or club that wants multiple seats, a shared library, and fleet-wide branding, the Club tier is built for exactly that — get in touch and I'll sort it out.

Fair question. The templates are my own original compilations, written in a consistent style from each aircraft's published procedures — never copied from a manufacturer manual, and never presented as the approved document. Each one is human-reviewed before its page goes live, with emergency content held to an especially conservative bar. You can read exactly how that works on the about page. And every template still tells you the same thing: verify it against your aircraft's POH.

You can absolutely build a checklist for an experimental or homebuilt — start blank and you have every element, color and layout available, including a panel-section framing that suits a custom build. If you want to push a checklist into your avionics (G3X, Dynon, and friends), the independent EFIS Editor linked in the hub handles that conversion; note its own site scopes it to experimental aircraft only.

Straight answer: your work doesn't vanish. The editor is local-first — it runs and prints from data in your browser, so anything you've already printed or exported keeps working no matter what. Export to JSON and PDF is always available, so you can take a portable copy of every checklist with you. A shutdown would be an inconvenience, not data loss. I'm not going to promise anything beyond what actually ships today.

The Fuel the project page has aviation-themed tiers and a custom amount — anything helps, and any amount unlocks branding for a year as thanks. If you can't right now, that's genuinely fine; using it free is the whole point.

Not a ForeFlight replacement in flight — this is the paper backup you build once and print. It complements your EFB and panel; it doesn't compete with them in the air.
