Privacy
How names are sent temporarily to the API, how data may remain in this tab or My stamps in this browser, and how analytics and external links work.

Input and image processing
Names are sent to the API to generate the image. Original names, SVG scenes and PNG data are not recorded in usage statistics or application logs. In-progress state is kept temporarily in the current tab. Recent stamps and stamps you choose to keep may be stored locally in this browser using IndexedDB for the stamp case feature, and may disappear if browser data is cleared.
Usage statistics and external services
API usage statistics exclude original names, IP addresses, PNG and SVG data and store only aggregate dimensions such as character count, shape, font, layout, effects, output size and response status. The web app may use Google Analytics, Naver Analytics and Microsoft Clarity to measure page visits and product flows.
Google Analytics and measurement data
On the production site, Google Analytics measures page visits, acquisition sources, generation success or failure, PNG downloads, sharing, stamp-case keep/edit/delete actions and non-identifying options such as character count, selected font and shape. Original names, stamp images and SVG/PNG data are not included in Analytics events. Arbitrary query strings and fragments are excluded from page URLs, while standard campaign parameters such as UTM values and Google ad click IDs are retained for attribution; referrers are reduced to origin and path. Google advertising and analytics use the standard tags without country-specific blocking or site-level wait logic.
Contact and external sites
Creation does not require email, but emailing support sends your address and message through mail services. Following official-source or Google Translate links lets external services process connection information. Do not send secrets or private documents.
Stamps stored in this browser
Input and results remain temporarily in this tab’s session storage. By default, up to five recent stamps are kept in this browser; records older than 24 hours are cleared the next time you create a stamp or open My stamps. Stamps you choose to keep remain until deleted. You can turn off automatic recent-stamp saving or delete entries in My stamps, but temporary tab data may still remain. There is no personal stamp archive on the server, so download any PNG you need.
Analytics, advertising and cookies
Operational statistics are kept for 90 days by default and do not include original names or IP addresses in aggregates. On the live site, Google Analytics, Naver Analytics and Microsoft Clarity may process cookies and browser or device information. Clarity masks name fields, result text containing names and stamp images. The site has no separate analytics consent dialog; Google's advertising consent notices remain separate. You can block cookies or delete them in your browser, but this does not delete information already sent to external services. Stamp creation and saving still work when analytics or advertising is blocked.
External services and privacy enquiries
Cloudflare delivers the website, and Google Gmail handles support email. Once an enquiry is resolved, the email and any separately saved attachments are deleted, except information that must be retained by law, which is kept separately. Photo background removal runs only in your browser and does not upload the photo to the server. Send privacy-related requests to the email address below. Changes and their effective dates are announced on this page.
