Privacy policy
Last updated 9 November 2026
The short version: Studykit has no accounts, no ads and no tracking cookies. Your files are processed on your own device and are never uploaded to us. A few text tools send text to a free outside service, and only when you use them. They are listed below.
Your files stay on your device
The PDF, image, document, slide and calculator tools run entirely in your web browser. When you open a PDF, a photo or a Word file, it is read and changed by code running on your computer or phone. It is not sent to Studykit or anyone else, and we never see it.
What is saved in your browser
To save you retyping, many tools remember your work and settings in your browser's local storage: for example your subjects and grades, documents, slides, flashcards, timetable, planner tasks and the light or dark theme. This stays on your device, is not sent to us, and is not shared between your devices.
You can delete it at any time by clearing this site's data in your browser settings. Local storage is not a cookie and is not used to track you.
Tools that use an outside service
These tools need a free public service to work. They contact it only when you press the button to run them.
- Grammar Checker: the text you check is sent to LanguageTool to find mistakes. Don't check text you need to keep confidential.
- Plagiarism Checker (online check): short phrases and sentences from your text are sent as searches to Wikipedia and OpenAlex. The “Compare documents” mode stays on your device. The Google and Bing buttons open those sites with the phrase you chose.
- Image to Text: the text-reading engine and language files are downloaded from the jsDelivr network the first time you use it. Your images are read on your device and are not sent anywhere.
Cookies, analytics and ads
Studykit does not set cookies, does not use analytics or advertising trackers, and does not show ads. If that changes, this page will be updated first and you will be asked for consent where the law requires it.
Server logs
Like every website, the company that hosts Studykit may record basic technical information when your browser loads a page, such as your IP address, browser type and the page requested. This is used to keep the site running and secure, and is kept for a short time under the host's own policy.
Children
Studykit is made for students of all ages. Because there are no accounts and we don't collect personal information, children can use the tools without sharing any details with us.
Changes and contact
If this policy changes, the new version will be posted here with a new date. See also the terms of use.
