Plans, accounts & privacy

This page explains the account, billing, and privacy surfaces in ThrustLab: when a plan limit stops or warns you, how to verify your email, how your acceptance of the Terms of Service is recorded, the "Do Not Sell or Share" privacy control, and the engineering-use disclaimer that appears on every result. The ⓘ next to any of these links straight to its section here.

Plans & limits

ThrustLab's plans gate a few features and run volumes. A control that needs a higher plan renders greyed out with a tooltip naming the plan, and a blocked run shows a contextual upgrade panel. Your billing page also shows a live usage meter so you can see where you stand against your plan's limit.

Compute-unit usage

The meter on your billing page shows how many compute units you've used in your current window against your plan's limit, with a progress bar and an upgrade nudge when you're near the cap.

How to read it. A compute unit is counted per physical rotor — a four-rotor static run costs four units, not one. The window is rolling: 24 hours on the free plan, 7 days on a paid plan. The "usage frees up in Xh" line tells you when your oldest in-window runs age out and that capacity returns to you.

Watch out. This is not a calendar reset. Nothing resets at midnight or on a fixed day — instead, each run frees up automatically once it's older than the rolling window. If the meter shows "Full quota available," you have no runs currently counting against your limit.

Upgrade required

A panel that appears when an action needs a higher plan than your current one — for example running a dynamic mission, a multi-axis parameter sweep, exporting CAD geometry, or hitting your daily free-run limit.

How to read it. It names exactly which feature is gated. Each gate has its own message: a daily-cap hit explains when your next free run frees up; a feature gate (dynamic, sweep, CAD export, the creator) explains which plan unlocks it. Upgrades are coming soon — until then the panel's action button is disabled.

Watch out. The free daily limit resets on a rolling 24-hour window, so a capped run frees up automatically — you don't have to upgrade to keep going the next day.

Greyed-out (plan-gated) controls

A control that needs a higher plan than yours renders greyed out in place. Hovering or keyboard-focusing it shows which plan unlocks it — Requires Hobbyist tier or higher or Requires Pro tier or higher — and clicking it does nothing.

How to read it. Parameter sweeps and creating an API key need Hobbyist or higher; adding a second sweep dimension, dynamic missions, and CAD export need Pro; the propeller creator's new/edit entries need Hobbyist or higher. Nothing is hidden — every control stays visible so you can see exactly what each plan unlocks.

Watch out. The greyed state reflects your plan as the page loaded. If it ever disagrees with the server, the server's answer wins — a blocked action shows the upgrade panel instead of failing silently.

+N more components on Hobbyist

A quiet footer line in the component picker showing how many more database components a higher plan unlocks. On the free plan you browse a curated subset of the motor, propeller, and battery database — plus every custom component you created yourself.

How to read it. It is information, not a button — clicking it does nothing. The number is how many additional catalog components become searchable on Hobbyist and up.

Watch out. Your own custom components are never gated — they stay visible and usable on every plan.

Your account

Verify your email

Confirms the email address on your account using the single-use link we email you when you sign up. You must verify before you can run a simulation.

How to read it. Opening the link lands you here, confirms your address, and sends you on to the dashboard. If the link has expired or you never received it, use the resend option to get a fresh one.

Watch out. The link is single-use and time-limited — if it doesn't work, request a new one rather than reusing an old email.

Accept the Terms of Service

The required checkbox at signup that records your acceptance of the in-force Terms of Service and Privacy Policy.

How to read it. Ticking it is required to create an account. We log the exact version of the terms you accepted, along with the date, so there's a clear record of what you agreed to.

Watch out. The version recorded is the one published when you sign up — the page never picks a different version on your behalf, and you can read the full terms via the links next to the box before you accept.

Using results responsibly

Engineering-use disclaimer

A reminder, shown on every result and on shared result pages, that ThrustLab's outputs are engineering estimates — not certified data.

How to read it. Treat results as a design aid. They must not be relied on for safety-critical decisions without independent bench testing and validation.

Watch out. Always bench-test and verify before committing a real build to flight. The binding terms (including the limitation of liability and the "not for safety-critical use" clause) live in the Terms of Service.
