FynLink™ - Private URL Shortener — Fynlink, LLC

Fynlink is a privacy-first URL shortener with zero ads & trackers.

Start free, no account or API key required. Your short link will be hashed (non-reversible) & the target link will be securely encrypted with a unique key derived from the actual short URL, even before reaching our servers.

Free use is limited to a maximum expiry time of 30 days per short URL. Default expiry time for new short links is 2 days (can be modified).

To make the most out of this extension, you will need an account. Paid plans start at $4/month. See our pricing page for more information.

Extension Features:
* Shorten any web URL or email links
* Target URL & title (can be altered) will be automatically set 
* Add an expiry date & time to your short URL using natural language (EG: In 5 minutes, Aug 24th 5PM etc)
* Add tags
* Modify slug
* Custom domain support
* Make a link private (will set link hidden in web application for you & any team members, private links will be visible to you only in browser extension)
* Pause or disable link analytic
* Set a preview page by default (Safe mode)
* Enable or disable local link history

Security & Privacy features:
* End-to-end encryption: your short URL, target URL, title, tags are end-to-end encrypted before sending to our servers. We cannot see your link data as we do not possess the keys to decrypt them.
* Have the option to show a link preview by default
* Can set a link hidden by setting it as private. The link will be hidden in your web application for both you and your team members, but will be visible to you in the browser extension (if history is enabled). This is by design, and not merely a hide/show functionality. The short URL is hashed (non-reversible) and the target URL is encrypted from a key derived from the actual short URL before sending to our servers. This means we cannot show the short URL and target URL without knowing the short URL in the first place!
