How can we help?
Practical, step-by-step answers written from the questions people actually send us. Every article shows when it was last verified against the live product.
Links
How do I change a link's destination after it is published?
Change where a Flyn short link goes at any time, on every plan: open the link, edit the Destination URL, save. The short URL, QR code and click history stay.
How do I change the title and image my link shows when shared?
Where the Social Preview fields live in the Flyn link editor, how to set a custom title, description and image on a short link, and what happens when you leave them blank.
How do I mask or cloak a short link?
Turn on Link Cloaking in a link's Advanced settings to keep your short URL in the address bar, plus the real reasons a destination refuses to be cloaked.
How do I password protect a short link?
How to add, change, or remove a password on a Flyn link, what visitors see at the password gate, and why free tool links expire after 3 hours.
How do I rotate one link between several destination URLs?
Split one Flyn link across up to 12 destinations with weights you set, then see how many clicks each destination actually earned on the link's analytics page.
How do I send visitors to different URLs by country or device?
Set device and geo routing on a Flyn link, with iOS and Android destinations, per country URLs, and the default destination unmatched visitors still get.
How do I set a link to expire?
Where the expiration date lives in the Flyn link editor, how to set or remove one on a link you already created, and what visitors see after a link expires.
Why did my free short link expire?
Links made with Flyn's free tools without an account are temporary, most last 24 hours and password links 3 hours. Sign up in the same browser to keep them.
Custom domains
How do I connect a custom domain to Flyn?
Add your own branded domain for Flyn short links: the exact DNS records to add, how verification works, and fixes for a domain stuck on pending.
How do I remove or disconnect a custom domain?
Removing a custom domain in Flyn takes the short links already on it offline. What removal does, what it leaves alone, and what to do before you delete.
My domain already has an A record, how do I connect it to Flyn?
Your website keeps its A record. Connect Flyn on a subdomain like go.yourbrand.com with a CNAME, add one TXT record, and your site stays online.
Analytics
How do I set up conversion tracking on my short links?
Turn on conversion tracking for a Flyn link, install the flyn.js tag on your site and thank-you page, and see which clicks turn into signups and sales.
Why are my clicks not showing or lower than expected?
Flyn counts verified human clicks only. Bots, crawlers, and chat app link previews are filtered out, and Free plan analytics cover the last 30 days.
Billing and plans
How do I delete my Flyn account?
Delete your Flyn account in Settings, Data & Privacy. Deletion happens 7 days after you confirm, your links pause at once, and you can cancel until then.
How do I upgrade, cancel, or change my Flyn plan?
How to upgrade to Flyn Pro, switch billing, or cancel. Pro stays active until the period ends, links keep working, custom domains pause after 14 days.
I bought the lifetime deal but my account still shows Free
A lifetime purchase is matched to a Flyn account by email address. If you paid with a different address than your account uses, here is how to fix it.
Integrations
How do I connect an AI assistant to Flyn with MCP?
Add https://www.flyn.to/mcp to Claude, ChatGPT, Cursor or another MCP client, sign in when the browser opens, and create, edit and track short links from chat.
How do I connect Flyn to Zapier?
Create a Flyn API key, paste it into Zapier, and connect the Flyn app. What to do when the connection is rejected, and why the option is missing on a free account.
Troubleshooting
My short link says "link not found"
Usually it is the domain, not the slug. Flyn issues new links on flyn.co while the dashboard sits on www.flyn.to, so the slug alone will not resolve there.
Why is my short link disabled or not working?
What it means when a Flyn link shows a disabled or expired page, why links get disabled by the safety system, and how to get a wrongly flagged link restored.
Still stuck?
Email [email protected] and a human will get back to you. Include your short link if the question is about a specific link, it cuts the back and forth in half.
