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.

Loading the website still requests pages and program files from the server. The server or cloud provider may retain normal network access information; the website cannot promise that network activity is never logged.

Images, PDFs, templates, QR content and name lists are processed in this browser's memory, without uploading files. PDF and OCR resources are served by this site and load on demand. OCR programs and language data download only after you click Start.

On-device translation runs in your browser and may require an initial language-pack download. Online translation contacts MyMemory only after you click Translate. The third party processes your text and network information under its own terms.
