Questions and practical limits

Tarkarn provides Android apps and four browser tool platforms. Use the home directory for tools and app pages for instructions and Google Play links.

The blog provides sample PDFs, reference outputs and rendered previews for merging, splitting, rotation and page inspection. Use those samples before trying your own document.

The PDF tools process selected PDFs in the browser without sending those files to our server. Network tools such as REST Client and WebSocket Client connect to the endpoint you enter. Read the notice on the individual tool before entering personal information.

Limits vary by tool, document content, browser and available device memory. A small sample succeeding does not guarantee a large document will work. Keep the original and check the output in a PDF viewer; use a smaller non-personal sample when reporting a failure.

Browser APIs, fonts and memory differ. Our public Node evidence covers the supplied synthetic PDFs. It does not prove every browser, encrypted or damaged file, digital signature, form or bookmark is supported.

This depends on the app and the feature you request. Translation can send source text and language choices to Tarkarn and its translation provider. Location-based earthquake alerts use registered alert locations. Google advertising and Firebase SDKs can process device and diagnostic data according to the app's settings. Read the app privacy policy.

Delivery depends on source data updates, the server, network connectivity, notification permissions and Android power settings. Alerts can arrive late or fail to arrive. Use official emergency channels for safety decisions.

The language button stores en or ko under tarkarn-lang in localStorage. Clear that entry or site data in browser settings to reset the choice. Blocking storage can prevent the choice from persisting.

Only the two existing library tutorial pages load AdSense in this site's current templates. Sample case articles do not load ads. Google may use cookies on pages that load its advertising scripts. The website privacy section links to Google and the separate web tool policies.
