1. Information Collection & Client Principles
Mamgain.app implements an on-device private-by-default architecture. Our core tools (MMark, MPCCare, MCreatorX) operate entirely offline. No usage data, diagnostics, or interaction logs are transmitted to our servers. MKundali's cloud features (birth chart storage, account sync) use Supabase with end-to-end encryption in transit.
2. Account Data
When you create an account, we store your email address and chosen display name in Supabase to authenticate sessions across apps. We do not sell, rent, or trade this information. Deleting your account permanently removes all associated data within 30 days.
3. Cookies & Local Storage
We use localStorage solely to persist your theme preference (dark/light) and session token on the current device. No third-party advertising cookies are placed. Analytics, if any, will be cookieless and aggregate-only.
4. Third-Party Services
Auth: Supabase (MKundali, MMark, MPCCare, MCreatorX). Payments (planned): Razorpay / Stripe — payment data never touches our servers. Android (108Rhythm): Firebase Auth and Google Play Billing. Each provider's own privacy policy governs their data handling.
5. Data Retention
Free-tier account data is retained for the life of the account. On deletion, data is purged within 30 days. Desktop app (MPCCare) data lives entirely on your machine and is never uploaded.
