Frequently asked questions
Common questions about short links, tracking, pixels, data ownership and 連.
What is a short link?
A short link shrinks a long URL into a compact link that redirects to the original on click. A good shortener does more than shorten — it lets you change the destination, track clicks, A/B-test and retarget.
Are short links safe?
The technology is neutral; safety depends on the provider. 連 automatically scans destinations when you create a link and blocks phishing/malware URLs to protect the whole shared domain from being blacklisted. You can also add password protection and expiry.
Is 連 (link.luvai.net) free?
Yes. The free tier lets you create up to 100 links with A/B & device routing, /suffix source tracking, FB/GA4/GTM retargeting pixels, click analytics, a QR & UTM builder, password protection and expiry.
Can I customize the slug?
Yes. Set your own slug when creating a link (e.g. link.luvai.net/spring), or leave it blank for a random one. Slugs are lowercased, so a casing mismatch never turns into a dead link.
Does changing the destination change the URL?
No. That's 連's core value — change the destination without changing the URL. Swap campaigns or move a landing page in the dashboard; every link you already posted or printed keeps working.
Does 連 have a REST API?
Yes. Generate an API key in the dashboard to create/manage links programmatically over a REST API — 1,000 free calls/month with usage metering. Docs at /developers.
Who owns my click data?
You do. Links, clicks and audience data live on LUVAI's own edge database, isolated under your account, with no third party reading or reselling your traffic — and you can export the whole lot any time. That's the biggest difference from most cloud shorteners.
Can I track click sources?
Yes. Built-in device / OS / source / country / hour / suffix / A-B-variant analytics, plus /suffix tags (e.g. /spring/ig, /spring/edm) for per-channel counts, a read-only shareable stats link and CSV export.
Can I use my own domain?
Yes. 連 supports custom branded domains (e.g. go.yourbrand.com), bound after a DNS TXT ownership check — which also satisfies Taiwan's NCC SMS-whitelist rule requiring an enterprise-owned domain.
Does it support QR codes?
Yes. Every link can generate a QR code; because changing the destination doesn't change the URL, a printed QR stays valid forever and can be repointed later.
