Privacy Policy

1. Who we are

Catalyst is a native Lua script editor and session manager for Roblox. This policy covers usecatalyst.dev and the Catalyst desktop application.

Write to support@usecatalyst.dev about anything on this page. It is the fastest route and it reaches a person.

2. What we collect, and why

Nothing on this list is optional flourish. If a row could be removed without breaking something, it would have been.

We do not collect your name, your Roblox account, your location, your device fingerprint, or a browsing history. There is no analytics package, no advertising network, no social plug-in, no session recorder and no tracking pixel anywhere on this site.

3. Our lawful basis

4. Who else sees your data

These are the only third parties involved, and each one is here because something on the site would not work without it.

Web fonts are served from this domain rather than from a font CDN, so no font provider ever sees that you visited. We sell nothing to anyone, we run no advertising here, and we share personal data with no one beyond the list above except where the law obliges us to.

5. Where your data is processed

We operate from the United States, and Groq and GitHub process data there too. Cloudflare serves the site from whichever data centre is nearest to you, so the page itself is usually served locally to you.

If you are in the UK or the EEA, using Catalyst means your data is handled in the United States, which does not have an equivalent data protection regime of its own. Where a transfer needs a legal mechanism we rely on the providers' Standard Contractual Clauses and, where the provider is certified, the EU–US and UK–US Data Privacy Framework. You keep the rights in section 7 either way.

6. How long we keep things

The retention column in section 2 is the whole answer. In practice this site stores almost nothing: there is no user database, no account system, and no mailing list. A chat transcript lives in your own browser tab and dies with it.

7. Your rights

Depending on where you live you have some or all of the following rights over your personal data: to access it, to have it corrected, to have it erased, to restrict or object to our using it, to take it elsewhere, and to withdraw consent you have given.

If you are in California, Colorado, Connecticut, Virginia or another US state with its own privacy law, you have the right to know what is collected about you, to have it deleted, and to opt out of its sale or sharing. We do not sell or share personal data, and we do not use it for targeted advertising or for any kind of profiling. Most of those state laws only bind businesses above a size or data-volume threshold that we are well below, but the rights above are honoured regardless of whether we are technically required to.

Exercise any of them by emailing support@usecatalyst.dev. We will answer within one month, free of charge. We may ask you for enough detail to find the data — usually the email address you paid with — because for most visitors we hold nothing that identifies you at all, and that is not us being obstructive.

If you think we have handled your data badly, tell us first. You also have the right to complain to the data protection authority where you live.

8. Age restriction

Catalyst is for adults. You must be 18 or older to download it, use it, or use this site. It is not directed at children, it is not marketed to them, and no part of it is designed to appeal to them.

We do not knowingly collect personal data from anyone under 18. If you believe someone under 18 has given us data, write to support@usecatalyst.dev and we will delete it and end the licence.

9. The desktop application

The app is licensed to a device rather than to an account, so when you activate a key it sends that key and a device identifier derived from your hardware to our licence server. That pairing is what stops one key being shared across a hundred machines. You can see both values in the app's Settings screen.

The scripts you write and save stay on your own machine. They are not uploaded, read, or backed up by us.

10. Security

The site is served over HTTPS only. API keys for the services above are held server-side and never reach your browser. No system is perfect, and we will tell affected users without undue delay if a breach ever puts their data at risk.

11. Changes to this policy

When this changes, the date at the top changes with it. If a change is significant — a new third party, a new category of data — we will say so in the Discord rather than quietly editing the page.

12. Contact

Email support@usecatalyst.dev. For anything that is not about your data, the Discord is faster.
