How to use Dodam Stamp

From making a chart to printing a certificate, just follow these steps.

Make a chart

Type your child's name. A nickname works great.
Pick a character and a theme. Choosing the boy or girl switches to a matching theme.
Choose one goal. Not on the list? Tap "Custom" and write up to 15 characters.
Choose a chart style: Fill the Stamps, Start → Finish, Weekly Chart, Monthly Calendar or Bingo.
Check the preview, then tap "Print on A4" or "Save as image (PNG)".

Put it up at your child's eye level, on the fridge, a door or next to the bathroom mirror.
Each time the goal is done, fill one box with a stamp or sticker you have at home.
When the last box (with the star or gift) is filled, it is certificate time.

Scan the QR code on the chart with your phone camera, or open the "Certificate" tab on this site.
Check the name, goal and chart style. If you made the chart on the same page, everything carries over.
Type a message and date, or choose "Write by hand after printing".
Print it or save it as an image and hand it to your child.

In the print window, choose A4 paper and "Default" or "100%" scale.
If the date and address print at the edges, turn off "Headers and footers".
To save ink, choose "Black & white". Decorations are removed and only lines remain.
On a phone, save as PNG and print from your photos, or take it to a print shop.

Is the name I type saved anywhere?: No. Everything stays in your browser and is never sent or saved. It disappears when you close or refresh the page.
Do I need to type everything again for the certificate later?: Yes, since nothing is saved. Scanning the QR code on the chart takes you straight to the certificate page.
Can I use stickers instead of stamps?: Of course. Stickers that fit the boxes, or circles drawn with a pen, work just as well.
Can I make a chart in Korean?: Yes. Tap "한국어" at the top right. Your entries stay, and the page, chart and certificate switch to Korean.
Does it cost anything?: No. Every feature is free.
