Frequently asked questions

Is this enough for GDPR?

It covers the banner UI and choice storage. For strict GDPR compliance you must also gate non-essential scripts until consent is given — see our GDPR checklist.

Does it load anything external?

No — the snippet is fully self-contained vanilla JavaScript.

Is this cookie consent banner generator free?

Yes — completely free, no signup, no usage limits, no watermarks.

Is my data uploaded to a server?

No. Everything runs client-side in your browser — your data never leaves your device, which also means it works on sensitive and confidential material.

Do I need to install anything?

No — it runs in any modern browser on desktop or mobile. Just open the page and use it.
