Privacy Policy

Last updated: March 1, 2026

1. Overview

This Privacy Policy describes how ClickClackLabs ("we", "us", "our") collects, uses, and protects information when you use BrainPickle ("the Service"). We keep things simple: we collect the minimum data needed to run the Service, and we never sell your personal information.

2. Information We Collect

Account information

When you sign in with Google or create an account with email and password, we receive and store your email address (and name/photo if using Google OAuth) to create and manage your account.

Quiz data

We store your quiz results, scores, streaks, and preferences to provide features like leaderboards, stats, and streak tracking.

Usage data

We collect anonymous analytics data such as page views, quiz completions, and feature usage to improve the Service. This data is not tied to your identity.

Referral and sharing data

When you arrive via a shared link, we may store the referral source (e.g. "whatsapp", "twitter", "sms") in your browser's local storage to understand which sharing channels drive engagement. This data is anonymous and not linked to your identity.

Email address for notifications

If you opt into streak reminders, we store your email address separately to send daily reminders when your streak is at risk. You can disable reminders at any time from your account settings, and your email will no longer be used for this purpose.

Group play data

When you join a group room, we store your display name, scores, and completion time to display on the room leaderboard. Room data expires automatically after 24 hours.

Local storage

We use browser localStorage to store quiz progress, streak data, install prompt state, referral source, and preferences locally on your device. This data never leaves your browser unless you have an account, in which case it syncs to our servers.

3. How We Use Your Information

  • Provide and operate the Service (quizzes, scores, streaks, leaderboards)
  • Display your name and scores on leaderboards (if you have an account)
  • Generate AI-powered quizzes based on your topic requests
  • Send transactional emails (account-related notifications)
  • Improve the Service based on aggregate usage patterns
  • Process payments for Premium subscriptions

4. Third-Party Services

We use the following third-party services that may process your data:

  • Supabase — database and authentication infrastructure
  • Google — OAuth sign-in and AdSense advertising
  • PostHog — product analytics (anonymous usage events to improve the Service)
  • Anthropic — AI quiz generation (your topic requests are sent to the Claude API)
  • Stripe — payment processing for Premium subscriptions
  • Resend — transactional email delivery (streak reminders)
  • Vercel — hosting and edge functions

Each service has its own privacy policy. We encourage you to review them.

5. Cookies

We use cookies for authentication (session cookies) and analytics. We may use third-party cookies for advertising (Google AdSense) and analytics (PostHog). When you first visit BrainPickle, we display a cookie consent banner. You can accept or decline non-essential cookies. You can also control cookies through your browser settings, though disabling essential cookies may affect the functionality of the Service.

6. Data Retention

We retain your account data and quiz history for as long as your account is active. If you delete your account, we will delete your personal data within 30 days. Anonymous, aggregated analytics data may be retained indefinitely.

7. Data Security

We use industry-standard security measures to protect your data, including encrypted connections (HTTPS), secure authentication, and access controls. However, no method of transmission or storage is 100% secure.

8. Your Rights

You have the right to:

  • Access the personal data we hold about you
  • Request correction of inaccurate data
  • Request deletion of your account and data
  • Export your quiz data
  • Opt out of marketing communications and email reminders

To exercise any of these rights, contact us at the email below.

9. Children

The Service is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal data, please contact us so we can delete it.

10. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of material changes via the Service or email. Continued use after changes constitutes acceptance.
