Frequently asked questions
Can't find what you're looking for? Get in touch.
Are these extensions really free?
Most are, completely. A couple offer an optional one-time "Pro" upgrade for extra features — there are no subscriptions or recurring charges anywhere on the site.
Do you collect my data?
No accounts, no analytics, no tracking. Everything runs locally in your browser. If a specific extension needs to talk to a server to do its job, that's called out explicitly on its own page — see the Privacy Policy for details.
How do Pro upgrades work?
Pro purchases are one-time payments processed by Lemon Squeezy, our Merchant of Record. They handle checkout, tax, and invoicing — we never see your card details. After purchase you get a license key that unlocks the paid features in the extension.
Can I get a refund?
Yes. If you're not happy with a Pro purchase, email us within 30 days and you'll get a full refund. See the Refund Policy for the full details.
An extension broke after a site update — what do I do?
Some extensions interact with third-party sites (YouTube, Google Calendar, etc.) that occasionally change their layout. Email a quick description of what broke and we'll fix it as soon as possible.
Can I request a feature or a new extension?
Always welcome. Send it over — most of what's on this site started as exactly that kind of request, including from myself.
Who builds and maintains unikdev?
One developer, solo. No team, no support bots — every message goes straight to the person who wrote the code. More on the About page.
