Your data in Bashidrum

What is stored

• The student's first name and the first letter of their surname, which is what the app shows. The app also keeps a short internal id made from the name the student was registered with.
• A username to sign in with (first name and surname initial, for example ringo.s) and the password, which is stored only in scrambled (hashed) form. Students do not need an email address to use Bashidrum.
• Practice data: which skills are open, the levels and tempos reached, exercises ticked, practice sessions and plans, trophies, notes from lessons, and when practice happened.

Listen mode uses the microphone only while it is listening to a run, on your device; no sound is recorded or sent anywhere.

Optional details (Settings, About you)

In Settings (the gear at the top), a student can add any of these. Every one is optional, and the app works the same without them:

• A recovery email (for students under 18, a parent or guardian's email), and a parent or guardian's name.
• A birthday (day and month; the year only if you want to add it).
• When you started playing drums, the kit you have at home, your favourite music, and what you want to get better at.

Only the student and Ben can see these. They never appear on the Leaderboard or to other students.

The recovery email is used only for sign-in help: if you tap Forgot password? or Forgot username? on the sign-in screen, a link to choose a new password, or your username, is sent to it. It is never used for anything else, such as news or marketing. Ben can add or correct the recovery email for a student; the other details are the student's to change.

Suggestions and problem reports

Settings also has Suggest or report, for sending Ben an idea or telling him something is broken. Ben reads every one. With each message the app adds the tab you were on, the app version and the time, so he can find the problem. Other students cannot see what you send.

Nothing else is kept. No address, no phone number, no photos.

Who can see it

• The student, and their parent or guardian through the same sign-in.
• Ben, the teacher, who runs Bashidrum.
• On the Leaderboard, other students in the class see your shown name, points, level, streak, trophies and, if you turn on rivals, your rival. They never see lesson notes, Ben's comments, your practice notes or your plans.

You can take yourself off the Leaderboard at any time with the switch on the Leaderboard tab. Then other students see nothing of yours.

Where it is kept

The records are held by Supabase, the database service Bashidrum runs on, in a data centre in the UK or EU. Supabase stores the data for us and does not use it for anything else. The app itself is hosted by Netlify. A copy of your own record (and the last Leaderboard) is also kept on your device so the app works offline; signing out removes it.

What is not done with it

No advertising, no analytics, no tracking, and nothing is sold or shared with anyone else.

Getting it changed or deleted

To remove any of the optional details, open Settings, About you, clear the fields and tap Save; they are gone straight away. For anything else, including suggestions you have sent, email Ben (the address you use to arrange lessons) and say what you would like corrected or deleted, and he will delete it. When a student leaves, their sign-in, practice record, details and suggestions are all deleted. You can also ask for a copy of everything held about you.
