Privacy Policy

Last updated: 12 May 2026

Trainkaki ("we," "our," or "us") is a solo project run from Singapore. This policy explains what data we collect, why, and how we handle it.

1. What We Collect

2. Where Your Data Is Stored

All data is stored on Supabase Postgres, hosted in Singapore (ap-southeast-1). Authentication emails are delivered through Resend. Both Supabase and Resend act as data processors on our behalf and do not use your data for their own purposes.

3. What We Do Not Do

4. Data Retention & Deletion

We retain your data for as long as your account is active. You may delete your account at any time from the app (You tab → Settings → Delete Account). Upon deletion, your personal data is removed within 30 days. Session chat messages and check-in records are retained in anonymized form to preserve the integrity of past sessions for other participants.

5. Children's Privacy

Trainkaki is intended for users aged 18 and over. We do not knowingly collect data from anyone under 18. If we learn that a user is under 18, their account will be terminated and their data deleted.

6. Your Rights

7. Changes to This Policy

If we make material changes, we will notify you via the app and email. Minor wording changes may be made without notice. Continued use of Trainkaki after a material change constitutes acceptance.
