Privacy & Usage

The image editor has no upload endpoint. Images, edits and exports stay in browser memory until you refresh or close the page. Self-hosted counters record tool views, button clicks, option changes, file selections and operation outcomes as daily totals retained for one year. They do not store images, filenames, input content, IP addresses or visitor IDs and do not use tracking cookies. The private statistics login uses a separate secure cookie. Do Not Track is respected. See Privacy & Ads in the footer for ad activation status, providers and data use. No remote fonts or image CDNs are used. Sponsored content is labeled Ad.
