Privacy Policy

We wrote this policy to be readable, not to bury you in legalese. If something is unclear, email us and we'll explain it plainly.

1. Who we are

Meridian is a study rhythm app operated by Rithik Sudhakar, based in Chennai, India.

Grievance Officer: Rithik Sudhakar
Email: hello@go-meridian.com
Address: Chennai, Tamil Nadu, India

We acknowledge complaints within 48 hours and aim to resolve them within 30 days.

2. What we collect

We collect only what we need to run the app.

Account: Your email address and display name (optional).

Study sessions: Energy level (1–10), effort rating, session duration, task name, session notes, focus quality, and distraction count.

Journal entries: Your written reflections and energy ratings. These may include personal thoughts and feelings — we treat this as sensitive personal data under India's IT Rules 2011.

Usage data: Which features you use and when, collected via PostHog analytics.

Payment: Handled entirely by Paddle — we receive your subscription status only, never your card details.

Not collected: Your real name (display name is optional), phone number, or location.

3. Why we collect it

We only use your data for the purpose it was collected for — nothing else.

Session and energy data → to calculate your regulation state and surface insights.
Journal data → to power your personal rhythm archive.
Email → to send your account credentials and optional product updates (only if you opted in).
Analytics → to understand how the app is used so we can improve it (PostHog, with your consent for EU users).

4. Sensitive personal data

Session notes, journal entries, and energy data may reflect your mental and physical health state. Under India's IT Rules 2011, Rule 3, we classify this as Sensitive Personal Data.

We never sell, share, or use this data for advertising. It is encrypted in transit (TLS) and at rest in our database.

5. Where your data goes

We use the following sub-processors to run Meridian. All transfers use industry-standard security (TLS, encrypted storage).

Supabase — database and authentication — United States — supabase.com
Paddle — payments — United Kingdom / United States — paddle.com
PostHog — analytics — United States — posthog.com
Resend — transactional email — United States — resend.com
Groq — AI support chat — United States — groq.com
Vercel — hosting and CDN — United States — vercel.com

For EU users: Supabase, PostHog, and Vercel operate under Standard Contractual Clauses (SCCs).

6. How long we keep it

Active account data: Kept while your account is active.
After account deletion: All personal data permanently deleted within 30 days.
Waitlist emails: Kept until you opt out, or 12 months after launch — whichever comes first.
Payment records: 7 years (legal requirement for financial records, held by Paddle).

7. Your rights

Access — request a copy of your data. Use the Export feature in Settings to download your session history instantly.

Correction — update your display name any time in Settings.

Erasure — delete your account in Settings → Danger Zone. Deletion is permanent and processed within 30 days.

GDPR rights (EU) — same email. We respond within 30 days.

8. Minimum age

Meridian is for users 18 and older. We do not knowingly collect data from anyone under 18. If we discover an account belongs to someone under 18, we will delete it immediately.

This age limit follows India's Digital Personal Data Protection Act 2023.

9. Analytics and cookies

We use PostHog for product analytics to understand how the app is used. For users in the European Union, analytics only run after you accept cookies via our consent banner.

No advertising cookies are used. No data is sold to advertisers.

10. Changes to this policy

We will notify you by email before making material changes. Your continued use of Meridian after a change takes effect means you accept the updated policy.
