TL;DR

Chitra collects no personal data. The only network call is fetching the wallpaper catalogue over HTTPS. Your favourites, theme, and search history live entirely on your device.

1

Who We Are

Chitra: Visual Cosmos (package: com.ashes.dev.works.chitra.cosmos) is an AI-generated wallpaper gallery for Android. This policy describes how data is — or deliberately is not — handled when you use the app.

2

Information We Do Not Collect

No account required. No sign-up. No login. Ever.

Chitra does not collect, transmit, or store on any server:

  • Personally identifiable information — name, email, phone number, or any identifier
  • Location data — no location permission is declared or used
  • Advertising ID — no ad network integrated; GAID/IDFA never accessed
  • Crash reports or diagnostics — no crash-reporting SDK of any kind
  • Usage analytics — no analytics SDK (Firebase, Mixpanel, Amplitude, etc.)
  • Personal photos or files — only wallpaper images you choose are touched
  • Device fingerprint or hardware identifiers
3

What the App Stores — On Your Device Only

All data Chitra persists is stored exclusively on your device using Android's SharedPreferences and a local Room/SQLite database. None of this is transmitted to us or any third party.

  • Favourites — Wallpaper IDs saved to SharedPreferences (favorites). Never leaves your device.
  • Search history — Last 10 search terms stored locally in SharedPreferences (search_history). Clearable at any time.
  • Theme preference — Your selected theme stored in SharedPreferences (chitra_settings).
  • Wallpaper catalogue cache — Metadata cached in a local SQLite database (chitra_db) for offline browsing. Stays on device.
  • Image file cache — Wallpaper images may be cached at filesDir/wallpapers/. Clearable via Settings → Clear Image Cache.
  • Onboarding flag — A single boolean (has_seen_onboarding) to track first-launch completion.
4

Network Requests

Chitra makes exactly one type of network request — fetching the wallpaper catalogue over HTTPS.

  • Endpoint — https://pub-634b904a2c6941709e6f4630e4d8cdb1.r2.dev/wallpapers.json
  • Protocol — HTTPS (TLS encrypted end-to-end)
  • What is sent — A standard GET request with a random cache-busting parameter (?cb=random_number). No user data or identifiers included.
  • What is received — A JSON catalogue of wallpaper metadata and image URLs. No user data involved.
  • CDN provider — Hosted on Cloudflare R2. Cloudflare may log anonymised request metadata per their policy: cloudflare.com/privacypolicy.
