Who we are

This site is operated by Sierra Tango Safety. Contact details are available on the main site.

What we collect

When you create an account we store your email address and, where provided, your display name. When you subscribe, our payment provider stores your billing details and shares a subscription record with us containing your plan, status and renewal date. We do not see or store your card details.

Why we use it

To create and secure your account, provide access to the question bank, manage your subscription, and respond to support requests. We do not sell your data or use it for advertising.

Cookies and local storage

We use essential storage in your browser to keep you signed in and to hold a local visit counter. The translation bar is provided by Google Translate, which may set its own cookies when used.

Retention and your rights

Account and subscription records are kept while your account is open and for as long as required for tax and accounting purposes. You may request access to, correction of, or deletion of your personal data at any time by contacting us.

Security

Accounts are protected by authenticated access and database-level access rules so that you can only see your own records.
