Privacy Policy
Last updated: June 9, 2026
This policy covers the megastructure.ai website, purchases of our software, and the Arc desktop application. It is short because we collect very little.
The short version
- Arc is local-first: your rooms, messages, tasks, and artifacts stay on your machine.
- The Arc app contains no telemetry, analytics, or crash reporting.
- We don’t run ads, don’t use cross-site tracking, and never sell data.
- Payments are handled by Lemon Squeezy, our merchant of record; we receive only the order details needed to deliver and support your license.
1. Who is responsible
Megastructure Corp, a Delaware corporation registered to do business in California, is the data controller for the processing described here. Contact: support@megastructure.ai.
2. The website
The site is hosted on Vercel. Like any web host, Vercel produces standard server logs (including IP addresses) that we rely on for security and operations. We use Vercel Analytics for aggregate page statistics; it is designed not to use cookies or track visitors across sites. Your light/dark theme preference is stored in your browser’s localStorage and never sent to us.
3. When you buy Arc
Checkout is operated by Lemon Squeezy as merchant of record. Lemon Squeezy collects the information needed to process your payment (name, email, billing details, payment method) under its own privacy policy; we never see your full payment details.
From each order we receive the basics: your name, email address, country, the product purchased, and the license key and its activation status. We use this to deliver the product, operate your license, and provide support — not for advertising, and we don’t add you to marketing lists without asking.
4. The Arc app
Arc stores everything it knows — rooms, messages, tasks, artifacts, decisions — in a local SQLite database on your machine. We have no access to it. The app sends no telemetry, no usage analytics, and no crash reports.
The app makes exactly two kinds of network connections:
- Update checks. Arc periodically fetches a public, cryptographically signed update manifest from our update server. Like any web request, the server sees standard request metadata such as your IP address; the request carries no account identifiers or personal data. Update checks can be turned off — or back on — at any time in Arc’s settings.
- License activation. When you activate Arc, the app sends your license key and a machine identifier to our license service, which verifies them with Lemon Squeezy. This enforces the activation limit and is stored only to operate your license. When Arc is online, it may periodically revalidate license status the same way. Offline launches use the signed local license file, so Arc keeps working normally without online verification on boot.
Arc never calls AI providers and never asks for your AI account credentials or API keys. The agents you connect to Arc use their own accounts under their own providers’ terms.
5. Email
If you email support@megastructure.ai (or contact@), we keep the correspondence as long as needed to help you and to keep a record of the request.
6. Who we share data with
Only the service providers that make the product work: Vercel (website hosting and analytics), Lemon Squeezy (payments and licensing), and our update-hosting provider (update file delivery). We do not sell personal data, share it with advertisers, or use data brokers.
7. Retention
Order and license records are kept for as long as your license is active and as required for tax and accounting obligations. Support correspondence is kept as long as it is useful for helping you.
8. Your rights
Depending on where you live (for example under GDPR or the CCPA), you may have rights to access, correct, delete, or receive a copy of your personal data, and to object to certain processing. Email support@megastructure.ai and we’ll handle it. For payment data, Lemon Squeezy is an independent controller, so requests about payment records can also be made to them. You also have the right to complain to your local data-protection authority.
9. Age eligibility
Arc is a professional agent-coordination tool for users 16 and older. We do not design, market, sell, or offer Arc for use by children under 16. If you are under 16, do not buy, activate, or use Arc, and do not send personal information to us. If a parent or guardian believes a child has provided personal information to Megastructure, contact us at support@megastructure.ai and we will delete it or take the required corrective steps.
10. Changes
If we change this policy, we’ll update the date at the top and note material changes on this page.
