Frequently asked questions

Yes. Core features — URL shortening, basic analytics, and link-in-bio pages — are useful and easy to get started with. No credit card required. The URL safety checker works without an account too.

Accounts created with email/password receive a verification link automatically — check your inbox and click it to confirm your address. Verification is optional, so you can keep using the site while unverified. You can re-send the link or check your status from the banner shown on your dashboard.

You can shorten URLs without one, but an account lets you save links, manage API keys, create a link-in-bio page, access full analytics, and send feedback. Create an account — supports Google sign-in or email/password.

Absolutely. When shortening, specify a custom back-half like /my-promo. Custom codes must be unique across the platform.

Expired links return an HTTP 410 (Gone) status. Visitors will see a message indicating the link is no longer available.

Every destination is screened at creation — phishing detection, reputation checks, redirect-chain analysis, DNS checks that block private networks, and local heuristics. Links are re-checked over their lifetime, so a site that turns hostile later gets quarantined behind a warning page or disabled entirely. You can also score any URL without shortening it via the safety checker.

Yes — head to the safety checker and paste any URL for an instant report: a 0–100 score, a clear Safe / Suspicious / Dangerous verdict, and a breakdown of every check that ran (domain health, reputation, redirects, phishing screening). No account needed, and there's a public API endpoint for the same thing.

Destinations are re-checked over a link's lifetime. If a site turns hostile after you create a link, it stops redirecting silently: visitors see a clear warning page describing the risk before they can continue, and severely dangerous destinations are blocked outright.

Yes. When shortening while signed in, enter a passcode in the shorten form — visitors will have to enter it before being redirected. You can also add or remove one later from the Edit panel of any saved link in your dashboard.

No. Links with a passcode are hidden from the Recently shortened feed so their destinations stay private. Anyone with the link can still reach the passcode prompt.

Only a salted hash of your passcode is stored — never the plaintext. It's not returned by any API, and it can't be read back from the dashboard once set. Brute-force attempts are rate-limited.

Click the QR button next to any saved link in your account dashboard. A QR code will appear that you can scan or download as a PNG image.

Yes. Open the QR panel for any link in your dashboard and click Download PNG. The image is named after the short code for easy identification.

Yes. QR codes are included with every link — no account required. Just shorten a URL and use the QR button to view or download it.

Yes. When creating or editing a saved link in your account dashboard, you can set a future activation time or an expiry. Until a scheduled link activates, visitors get an error instead of a redirect.

Yes. Signed-in users can connect a custom domain they own and serve short links from their own web address. Follow the on-screen DNS verification steps — links created on the domain use your branding.

Yes. The code generator turns any URL, SKU, or serial into a scannable QR code or 1D barcode (Code 128, Code 39, EAN-13, UPC-A, ITF-14) — with PNG or SVG download, custom colors, and a logo on QR codes.

Go to /link while signed in, choose a username, add your social profiles and custom buttons, and hit save. Your public page will be at /@yourusername.

Yes. Edit your username in the bio editor and save. Your old URL will stop working, so update any shared links.

You can add up to 40 links — a mix of social profiles and custom buttons for shops, newsletters, portfolios, and more.

On the /link page, click the QR button next to your bio URL. A QR code for your page will appear — scan it with your phone or click Download PNG to save it as an image.

On the /link page, use the ↑ and ↓ arrows next to each social profile or custom button to move it up or down. The order you set is reflected on your public page after saving.

Changes to your profile, links, and link visibility only take effect after you click Save page. Make sure to save before sharing your page so your updates are live.

Check the analytics section in your account dashboard. You'll see total clicks, platform breakdowns, and referrer data for every link.

Sign in, navigate to the API keys section in your account, and create a new key. Keep it secret — it grants full access to your account's API capabilities.

Webhooks push real-time click events to an HTTPS endpoint you control whenever one of your links or codes is opened. Configure one from the Webhooks section of your account — with an optional HMAC secret so you can verify the payload came from ilync.

Yes. The code endpoints generate QR codes and 1D barcodes with your API key, returning PNG or SVG — useful for automation and product pipelines.

Click the chat button at the bottom-right corner of any page. Choose a topic from the dropdown, write your message, and submit — no account needed. If you're signed in, your feedback is linked to your account so we can follow up.

The development team reviews every submission. Bug reports, feature requests, and UI feedback all help shape what we build next.

Yes. The admin dashboard includes a Feedback section where administrators can browse, filter by type, and review all submissions in one place.
