Questions

Are these tools really free?

Yes. The calculators, visualizers, palette tools, quiz and checklist run entirely in your browser and cost nothing to use. No account is needed.

Do you upload my photos?

Not in the free tools. Photos you use for the palette, photo check or slider stay in your browser. A photo is only uploaded if you create an account and ask for an AI render.

When do I need an account?

Only for AI renders on your own photo. A free account includes free credits for eligible new sign-ups, and free results carry a small watermark.

Where do the cost numbers come from?

Each calculator cites the public cost guides and reports it uses, shown under "Estimates, sources" on the page. They are planning estimates, not quotes.
