Privacy & processing
Your content should not travel without a reason.
Every Unidec tool declares its processing model before you choose a file. The tools currently marked “On-device” run inside your browser and do not send selected content to Unidec.
Current local tools
All currently available Unidec tools process selected content on your device. Working files and generated download URLs are temporary unless a tool explicitly offers local autosave and you allow it; Sketch Essentials is the current exception and may save its editable document, including inserted images, in this browser. Camera scanning begins only after permission and stops when a QR code is found, you stop it, or the page closes.
Password & Security Essentials uses the browser’s cryptographic random generator. Generated values remain only in the current page state and are never automatically copied, saved to local storage, or included in a network request.
Calculator Essentials evaluates expressions and everyday formulas entirely in the current page. Its temporary history is not saved and is cleared when the tab closes or the page refreshes.
Metadata & Privacy Cleaner inspects and rewrites supported JPEG, PNG, WebP, and PDF files in browser memory. Image metadata blocks are removed without recompressing visible pixels, color profiles are preserved, and content credentials are preserved unless explicitly selected for removal. Signed PDFs are not rewritten.
Screen Capture Essentials requests display and optional microphone access only after you press start. The browser controls the source picker and sharing indicator. Captured frames and recording chunks remain in the current tab; active tracks stop on completion, cancellation, or page exit.
CSV & JSON Essentials parses, profiles, transforms, and exports structured text in browser memory. Selected files and pasted values are not uploaded or persisted. Spreadsheet-formula protection changes exports only when you enable it.
Color & Design Essentials converts and generates colors in page memory. Uploaded images are decoded locally for pixel sampling and palette extraction. The optional eyedropper opens only after a button press and is controlled by the browser.
PDF Fill & Sign renders and edits PDFs in browser memory. Visible signatures are flattened into the downloaded copy; they are not identity-verified or certificate-backed digital signatures.
Browser storage & cookies
Unidec uses no advertising, analytics, or tracking cookies. Cookie-free Vercel Web Analytics runs separately from the local-storage choice. One necessary browser-storage entry remembers that choice. If you save local preferences, Unidec also stores your theme, language, pinned and recent tools, recent conversions, and sketch autosave in this browser. “Do not save preferences” removes and disables those optional entries. You can change this at any time through Privacy settings in the footer.
Video engine download
Video Essentials downloads a pinned WebAssembly media engine from jsDelivr when it is first used. This is a normal program-file request; the selected video is not included or sent to that provider. The interface discloses this download before file selection.
OCR language model download
Document Scanner & OCR downloads the chosen English or German recognition model when it is first used. The request contains only program and language-model files; selected images remain in browser memory. The interface discloses this before image selection.
Future server tools
No current live tool uploads files. AI and other future tools are not presented as live until their processing, deletion, security, and acceptable-use policies are defined. If a future tool needs an upload, Unidec will say so before file selection and publish a retention period and delete-now option.
What local tools still expose
Your browser and device still know which files you select. Browser extensions, operating-system software, and downloaded files remain outside Unidec’s control. Use a trusted, up-to-date browser for sensitive material.
Anonymous analytics
Unidec uses Vercel Web Analytics to count page views and client-side route changes. Vercel states that Web Analytics uses no cookies, stores anonymized aggregate data, does not associate events with an individual or IP address, and resets its visitor hash each day. A data point may include the timestamp, page URL and route, referrer, filtered query parameters, approximate location, operating system, browser, and device type. Unidec removes URL fragments before transmission, so shared sketch data is excluded. No custom events are configured: filenames, file contents, pasted or searched text, generated values, and tool outputs are not sent as analytics properties.
