Service information
A plain-language overview of the information TechDrill uses to provide the service.
Effective September 4, 2026
Account information includes your email address, display name, sign-in provider, account roles, and authentication records needed to operate your account.
Study information includes quiz sessions and answers, history, bookmarks, favorites, ordering preferences, custom collections, personal questions, and question overrides that you choose to create.
If you contact support, TechDrill may retain the information in your message for as long as needed to respond and resolve the request.
This information is used to authenticate you, keep your study data available across devices, provide requested features, maintain account security, diagnose problems, and respond to support requests.
TechDrill does not currently use advertising, marketing email, or nonessential analytics, and it does not sell personal information.
TechDrill uses Supabase for authentication and database services, Vercel for application hosting, and Google only when you choose Google sign-in. These providers process information needed to deliver their services and may process it outside Canada under their own terms and privacy practices.
You can review the Supabase Privacy Policy and Vercel Privacy Notice. Google provides its own notice during the OAuth sign-in flow.
TechDrill uses essential session storage and cookies to keep you signed in and protect authenticated requests. There are currently no TechDrill advertising or nonessential analytics cookies.
Account and study information is retained while it is needed to provide your account and preserve the history you ask TechDrill to keep. You can edit your display name and much of your personal study content directly in the application.
Self-service account deletion is not currently available. To request access, correction, or deletion of account information, email cskash24@gmail.com. Identity verification may be required before an account request is completed.
TechDrill uses access controls and database row-level security to separate user-owned information. No internet service can guarantee absolute security.
This notice may be updated as TechDrill changes. Material changes will be reflected on this page with a revised effective date.
