Class Calc Graphing Calculator 與 WolframAlpha Classic 使用情況與統計

Test-safe Statistics, Graphing, Scientific and Matrix Calculator. 100% Free. No Ads. No “upgrade To Unlock” Functions. All Equivalent Functions Of A Ti 84 Calculator, X84, Casio Calculator Or Hp Calculator. Paying $100+ For A Ti 84 / Ti Nspire Graphing Calculator (Or Casio, Or Even Hp) Is Just Silly. Here’s Our Logic: 1. We’ve Built A Beautiful, Easy To Use Online Digital Calculator Right There On Your Phone. 2. The Problem Is, That You Can’t Use Your Phone On Tests, So You’re Stuck Paying $100+ For Your Calculator. 3. With Our Easy-to-use Test-mode Lockdown, You Can Now Use Classcalc On Tests. Teachers Can Ask Students To Temporarily Lock Their Own Devices* Out Of All Outside Distractions Such As Instagram, Calls And Texts, Keeping Students Focused In Class, And Preventing Cheating On Tests. Students Can Leave Test Mode Whenever, And Once They Do, The Teacher Is Notified.

Why do we need accessibility permissions when you're joining test mode? In order to give teachers full trust that the students can't access data from other apps while on test mode, we make use of the accessibility services to make sure the student is using ClassCalc and only ClassCalc. Your data is 100% safe. We don't collect any data displayed on the screen. We analyze the behavior locally and only ask the teacher to make sure everything is fine on the student's end - no data is sent over. Contact: Info@classcalc.com
