Skeddo uses deterministic mathematics: calculateCanMiss evaluates how many sessions you can miss while remaining at or above your target percentage, and calculateMustAttend calculates how many consecutive sessions you must attend to recover from a deficit.
Yes. Skeddo is built with an offline-first architecture. All records are stored locally in your browser storage or device cache so you can mark attendance and view your schedule even in low-connectivity classrooms.
No. Skeddo is an independent student productivity tool. Results are estimates based on user-entered values. Your institution's attendance rules, subject requirements, and scheduled classes may differ.
