Privacy Policy

1. Who We Are

Nuskha (नुस्ख़ा) is published by StackMap and operates the Android application ai.stackmap.nuskha and its web companion at https://nuskha.stackmap.ai.

2. Zero User Accounts & On-Device Storage

Version 1.0 of Nuskha does not require account creation or sign-in, and does not bundle Google Sign-In, Firebase Analytics, or Firebase Crashlytics.

• Local Sandbox Storage (Hive): Your saved bookmarks, custom daily routines, completion streaks, Family Health Profile names/avatars, Nuskha Pro entitlement cache, and locally submitted Dadi's Hall of Fame recipes are stored strictly in private app storage on your device.
• Android Backup Disabled: Our Android manifest sets android:allowBackup="false" and android:fullBackupContent="false" so local health and routine preferences are not automatically copied to cloud backups. Uninstalling the app deletes all local data.

3. Read-Only Public Content Sync (Supabase)

When your device has internet access, the app sends read-only HTTPS GET requests to our public content backend (mwszkoimxymbyuhirrht.supabase.co, Mumbai ap-south-1) to check for remedy updates (<100 bytes timestamp check), fetch newly published remedies, load curated Shorts metadata, and retrieve curated ingredient store links. Zero personal user data, bookmarks, or profile names are uploaded during this sync.

4. Non-Personalized Advertising (Google AdMob)

On the free tier, Nuskha displays banner ads via the Google Mobile Ads SDK configured strictly with nonPersonalizedAds: true (Nuskha Pro users see zero ads). Because the Google Mobile Ads SDK includes the Android Advertising ID permission (com.google.android.gms.permission.AD_ID), Google's SDK may transmit over encrypted HTTPS:

• Device or other identifiers (Advertising ID, for frequency capping and fraud prevention);
• Approximate location (IP-derived at SDK level);
• App interactions (ad impressions and taps) and SDK diagnostics/performance signals.

5. Embedded YouTube Shorts

When you explicitly open the Shorts tab online, videos stream via YouTube's privacy-enhanced embed domain (https://www.youtube-nocookie.com). Viewing embedded videos connects to YouTube/Google servers and is governed by Google's Privacy Policy .

6. Google Play Subscriptions (Nuskha Pro)

Optional Nuskha Pro subscriptions (Monthly Plan at ₹29 / month and Annual Plan at ₹149 / year) are processed exclusively by Google Play Billing. StackMap never receives or stores your credit card, UPI, or banking credentials; only your active subscription entitlement status is verified with Google Play and cached locally on your device.

7. Sharing, Ask AI & External Store Links

• WhatsApp & Ask AI Shares: Triggered strictly on your tap using Android's native share sheet. If you share text into Nuskha via Android ACTION_SEND, ingredient keywords are matched locally in memory on your device and are never uploaded.
• Affiliate Store Links: Tapping a recommended product card opens the external merchant website or app (such as Amazon India or Flipkart) over HTTPS. StackMap may earn an affiliate commission at zero extra cost to you.

8. Web Companion Privacy (https://nuskha.stackmap.ai)

This web companion is a static website hosted on Cloudflare Pages. Our client-side What's In My Kitchen? ingredient lookup executes 100% inside your browser with zero user tracking cookies or account forms.
