Privacy policy
What we collect, why, and how to have it removed.
Reading the site
You can read every question without an account and without giving us any personal information. Your choice of quiz or learning mode is stored in your own browser and is never sent to us.
If you create an account
We store only what the account needs to work:
- Your name, as shown on questions you contribute
- Your email address, used to verify the account and to reset a password
- Your password, stored only as a cryptographic hash and never in readable form
- The date of your last sign-in
- The questions you submit, together with their review status
Verification codes sent by email are stored hashed, expire after a short period, and can be used once.
Security records
Administrative actions — approving or rejecting a question, changing a role, suspending an account — are written to an internal log so problems can be investigated. These records deliberately exclude passwords, verification codes, reset tokens and session identifiers.
What we do not do
- We do not sell or rent your information
- We do not share it with advertisers
- We do not require an account to read the question bank
Removing your data
You can ask for your account and personal details to be deleted at any time. Questions you contributed that have already been published may remain on the site, since other people rely on them, but they can be detached from your name on request.
Changes to this policy
If this policy changes in a way that affects you, the updated version will be published on this page.
