Support

Purchases, licenses, refunds, and invoices — start here

1. Contact

Please include your merchant order number (starts with LB…), your OS and IDE version, and a screenshot or description of the issue.

2. FAQ

I paid — where is my license?

The confirmation page shows the license and download right after payment; the Alipay return page also has a "Get download" link. If you missed it, retrieve the order by order number, or email support for a reissue.

Can I use my license after reinstalling or switching machines?

Yes. Licenses are tied to the order; the exact device terms are shown on the purchase page. Reinstalling usually does not require repurchasing — contact support if anything is stuck.

How do I get a refund?

See the Refund Policy: within 7 days of purchase, no questions asked, full refund by email request.

Do you provide invoices?

Chinese e-invoices (fapiao) are available — see Invoice Information. Overseas customers receive an equivalent receipt.

Personal use vs company use?

Personal use is free for now, with nothing crippled; using Libra inside a company requires a business license (¥299 / company / year, unlimited seats) — see the business page. You can also support development on the sponsorship screen — sponsoring is not a purchase.

3. Hours

Email is monitored around the clock; human handling runs 9:00–18:00 Beijing time on business days. The payment channel (Alipay) is available 24/7.

4. Security and privacy

License verification transmits only the order number and a machine fingerprint — never your code or personal data. See the EULA.
