Privacy Policy
How we collect, use, and protect your information.
Last updated: 28 March 2026
1. Who we are
Your BrainPrint is an ADHD coaching practice and companion web application operated by Kris Cernjavic, Armstrong Creek, Victoria, Australia.
2. What we collect
Website visitors
When you browse our marketing pages, we collect minimal data. We use privacy-respecting analytics that do not use cookies or track you across sites. No personal information is collected unless you choose to provide it (e.g. by booking a call or signing up for the newsletter).
Companion app users
When you create an account and use the companion app, we collect:
- Account information: your email address, display name, and authentication details.
- Onboarding responses: focus areas, work type, schedule, and optionally self-reported conditions.
- Daily tracking data: energy levels, mood ratings, sleep quality, activity logs, and any notes you choose to add.
- App usage data: feature interactions and preferences (e.g. notification times).
Coaching clients
If you book coaching sessions, we also collect contact details and session notes relevant to your coaching engagement.
3. How we use your data
We use your data to:
- Provide and personalise the companion app experience.
- Generate pattern insights and weekly summaries from your tracking data.
- Send check-in and debrief reminders at your chosen times.
- Deliver coaching services you have requested.
- Send newsletter emails if you have subscribed (you can unsubscribe at any time).
- Improve our services based on aggregated, anonymised usage patterns.
4. Health-adjacent data
The companion app collects data related to energy, mood, and sleep. While this is not clinical health data, we treat it with the same care. Specifically:
- Your tracking data is never shared with third parties for advertising or marketing purposes.
- Self-reported conditions (e.g. ADHD, anxiety) are optional and never required.
- Analytics tools do not receive mood, energy, sleep, or condition data.
- If you use the coaching bundle, your data is only shared with your coach after you give explicit consent.
5. Data storage and security
Your data is stored in Supabase (PostgreSQL) with row-level security, meaning you can only access your own data. All connections use HTTPS encryption. We do not sell, rent, or trade your personal information.
6. Your rights
You have the right to:
- Access your data at any time through the app.
- Export your data (available to premium subscribers, or on request for free tier users).
- Delete your account and all associated data at any time through the app settings.
- Withdraw consent for optional data collection (e.g. conditions, coach data sharing) at any time.
7. Cookies
Our marketing website does not use tracking cookies. The companion app uses essential cookies only (authentication session tokens). No third-party advertising or tracking cookies are used.
8. Third-party services
We use the following services to operate:
- Supabase — database and authentication.
- Vercel — website and app hosting.
- Stripe — payment processing (for premium subscriptions).
- Microsoft 365 — email and booking management.
Each of these services has its own privacy policy. We only share the minimum data necessary for each service to function.
9. Changes to this policy
We may update this policy from time to time. Significant changes will be communicated via email to registered users. The "last updated" date at the top of this page will always reflect the most recent version.
