How it works
From account to canvas in three steps.
Create an account, make your contribution, review the live cost, and commit only when you are ready.
Step 1
Create account
Sign up with your email and connect a payment method through Stripe. Your card details stay with Stripe — they never touch BidMosaic.
Secure payment setup before you begin editing.
Step 2
Add your art, thoughts, emojis
Draw, type a message, drop in an emoji, or upload an image — express whatever you want on the canvas. Undo, redo, or revert anytime before you commit.
Nothing is charged while you are still composing your edit.
Step 3
Commit when you are ready
Review the live pixel count and total cost, then confirm. Your design becomes part of the mosaic, and your contribution funds the cause.
The final price is shown before the edit becomes permanent.
Every pixel matters
Every change has a price.
You pay only for the pixels that actually change. Each time a pixel is replaced, its price rises incrementally. Quiet areas stay inexpensive, while heavily contested areas cost more to change.
You always see the calculated cost before committing an edit.
The live canvas always moves forward
Your pixels can be overwritten.
Your art and words can be replaced, but it does cost the next person a bit more and you can alway redraw.
Though your words or drawing may be overwritten, they are preserved in the canvas history, so people can look back and see how the image changed over time.
The live canvas shows only what exists now. History shows what used to be there.
Payments and policies
Secure checkout and mosaic policies.
These rules explain how balances, pixel purchases, moderation, and refunds work once an edit is committed.
Payments
- Payments are processed securely through Stripe; your card details never touch BidMosaic servers.
- Funds you add to your balance are held for future use and are not refundable after purchase.
- Erasing, recoloring, or editing pixels are treated as new purchases at the current price.
Content & conduct
- Hateful, harassing, sexual, illegal, or otherwise inappropriate images, text, or comments will be removed at the discretion of BidMosaic or the organization that set up the mosaic — and removed content is not refunded.
- Pixels overwritten by other supporters, or moderated for any reason, are not refunded. Like paint on a community mural, the cost of placing pixels is non-recoverable once they are committed.
- Repeated abuse may result in account suspension without refund.
Once pixels are committed, their cost is non-recoverable—even when they are later overwritten or removed through moderation.
