Frequently asked
What's your refund policy?
All paid tiers are refundable within 14 days of the initial purchase, no questions asked. Email [email protected] with your order number. Monthly and Team can also be cancelled anytime to stop the next renewal.
Does Lingua work offline?
Desktop core editing and bundled JS, TS, Python, and Ruby runtimes work offline; Go and Rust need installed local toolchains. License tokens verify offline. The browser app needs a first online load; its service worker can reuse cached app assets, but an uncached asset or new version may need the network. HTTP requests, remote AI, trial signup, and other online services still need connectivity in either edition.
Can the local MCP server or CLI run my code?
Desktop local MCP exposes only bounded read-only project tools after you authorize a root; it never runs code. The separate CLI can validate a Run Capsule without executing it. Its explicit replay and run commands do execute trusted code with your operating-system permissions. See the agent integration guide.
Can I try Pro before paying?
Yes — 14 days, no credit card. Open Lingua, go to Settings → Account → License → Try Lingua Pro free for 14 days, enter your email, and click Start free trial. The token activates automatically (no manual paste). One trial per email and per device.
How does the education program work?
Verified students and educators get free Pro for one year, renewable. Open Lingua → Settings → Account → License → Educational license, enter your school email (any .edu domain plus .ac.uk, .edu.mx, .edu.au, .edu.ca, .edu.br, and .ac.in), and confirm with the magic link we send you. The token arrives by email and pastes itself into the app.
Can I move my license between machines?
Yes. A Pro license is bound to a small set of devices (currently three). When you buy a new machine, deactivate the old one from Settings → Account → License — the license server frees the slot immediately. Signature checks stay offline, so a launch never waits on the server.
What happens after my one-time Pro updates end?
Your paid features stay unlocked forever. The one-time Pro purchase includes 12 months of new releases; renewal is optional if you want to keep your update eligibility current. Your signed token continues to work offline.
Lingua is source-available, not open source — see the licensing page for the exact scope of what you can do with the code.
