Privacy and saved work

These utilities run locally in your browser. There is no account or automatic upload of tool inputs. Plans, grade models, reading lists, focus logs and flashcards are saved in localStorage on this browser when available. Selected PDFs and images remain in memory only. Export a workspace JSON backup and download generated PDFs before clearing browser data. Backups contain your study records; keep them somewhere you trust. The hosting service receives ordinary page requests, including network information such as your IP address.

Offline access

A service worker downloads static pages and tool code for offline use after the initial visit. Check the homepage workspace status before disconnecting. Private browsing, storage limits or clearing site data can remove saved work and cached pages. The hosting service is needed for the first download and updates, but study tools have no backend.

Editorial approach

Our guides explain practical workflows with examples and reusable templates. Outputs are starting points: check academic facts against your course materials. Calculators show estimates, not guarantees about grades or memory.

Accessibility

Use a keyboard to navigate fields and buttons. Text output can be copied into your preferred editor. PDF exports are visual worksheets; retain the text version when an accessible document is required.
