One inbox, one person
Quiet Paper Studio is a one-person operation. Bug reports, feature requests, questions, and quiet feedback all go to the same email: [email protected].
Replies usually within 48 hours. I read every message.
Reporting an app bug
If something's wrong with one of our apps (Tessera, Lattice, or Doublet), please include in your email:
- Which app (Tessera / Lattice / Doublet)
- Device + OS version (e.g., "iPhone 15 Pro, iOS 18.2" or "Pixel 8, Android 14")
- Which world + level, if it's level-specific
- What you expected vs what actually happened
- Steps to reproduce, if you can
The more specific, the faster I can fix it.
In-app help
Each app has built-in tutorial / how-to-play screens accessible from its main menu or settings. For app-specific FAQ — common questions about hints, progress, purchases, language switching — see the support page linked from each app's App Store or Google Play listing.
Refunds and purchases
App purchases are processed by Apple (App Store) or Google (Google Play). Refunds are governed by those stores' refund policies, not by us — we don't see your card details and can't process refunds directly. To request a refund:
- Apple App Store: reportaproblem.apple.com
- Google Play Store: support.google.com/googleplay/answer/2479637
If a refund is denied by the store and you believe it was unfair, email me — I'll take a look, though final decisions rest with the store.
Press and partnerships
Same email: [email protected]. Include "Press" or "Partnership" in the subject so it surfaces. Quiet Paper Studio is a small one-person operation — I can't always say yes, but I read everything.
