Privacy by design
File tools on YYY Tools run in your browser. Selected files are not sent to a YYY Tools processing server.
Local file processing
The browser reads the file and performs the operation on your device. By default, task files and results stay in temporary memory and are lost when the page is closed or refreshed. The recent-task recovery cache is limited to 8 tasks and 100 MB; processing and previewing files can require additional browser memory.
Favorites and optional local recovery
Saved tool identifiers are stored in your browser's localStorage, without file contents. If you enable "Keep workspace on this device", task inputs, file names, settings, results, and workflow progress are stored in this browser's IndexedDB. This is not cloud storage or an upload. Recovery is limited to 8 tasks and 100 MB. Data older than 24 hours is discarded the next time the workspace opens; it is not a guaranteed background deletion timer. Password generation, HMAC generation, JWT decoding, and URL parsing are excluded from workspace recovery. Pages can still hold entered values in memory until reset or a full page unload; copies and downloads are not cleared by resetting the tool. Avoid enabling recovery on shared devices. Browser settings, storage quotas, or private browsing can prevent saving or remove saved data.
Memory only
Up to 8 tasks / 100 MB. Recovery expires after 24 hours. Password, HMAC, JWT, and URL tasks are not saved.Website requests
Loading the site requires normal requests for page code and static assets. This statement concerns the files you select for processing; it does not claim that the site makes no network requests at all.
Limits and compatibility
Browser memory, available codecs, file format, and device performance can affect whether a task succeeds. Large files may fail on memory-constrained devices. Never use an online tool as the only copy of an important file.
Analytics
This version has no account system, payment tracking, third-party analytics, or file-upload service. Technical processing limits still apply. When operational diagnostics are enabled, unexpected page errors send only a fixed error-category code and a public catalog tool identifier to this site. Error messages, stack traces, file contents, file names, input text, generated secrets, and local paths are excluded. Hosting infrastructure may record standard website requests, including connection information. Diagnostics do not use cookies or persistent visitor identifiers.
