About

Jimper Studio is a one-person indie development studio. I design, build, and ship mobile applications and web experiences using modern AI-assisted workflows. Every product is crafted with attention to performance, accessibility, and user trust.

Current focus: language-learning tools with interactive mechanics and subscription-supported sustainability.

Monetization Model

My apps use transparent, user-friendly monetization strategies that respect player experience:

Ad-Supported Free Tier

Users can access core features at no cost. Ads are shown via rewarded video and non-intrusive banners through certified networks.

Subscription Upgrade

An affordable annual subscription removes ads and unlocks premium features like unlimited practice and advanced analytics.

One-Time Purchases

Selected projects may offer lifetime unlock options for users who prefer a single payment.

Privacy First

No third-party tracking beyond essential ad attribution. All payment processing follows PCI-compliant vendor standards.

Refund Policy

All payments, subscriptions, and in-app purchases are processed exclusively through third-party platforms (including but not limited to Google Play, Apple App Store, Paddle, and any other distribution channels we may use in the future).
