Privacy Policy

Last updated: September 6, 2026

Tsumige is made by okojo (Siu), an independent developer in Japan. This policy explains what the app does with your data. The short version: your pile stays on your device, and we do not run accounts or ads.

Data stored on your device

Games you add, their status, ratings, reviews, play time, and any cover photos you choose are stored locally on your device (and in the app group container shared with the Tsumige share extension). We cannot see this data. Deleting the app deletes it.

Game search

When you search for a game, the title you typed is sent to our proxy server (hosted on Cloudflare Workers) which forwards it to the IGDB API (operated by Twitch) to fetch game titles, cover art, platforms, genres and time-to-beat data. We do not attach your identity to these requests. Search results may be cached on the proxy for up to 24 hours to reduce load. Cover images are loaded directly from images.igdb.com.

Purchases

In-app purchases are processed by Apple and managed through RevenueCat. RevenueCat receives an anonymous app user ID, your purchase receipt, device type and locale so that your Pro entitlement can be restored across devices. RevenueCat does not receive your name, email, or the games in your pile. See RevenueCat’s privacy policy.

Sharing

Share cards are images generated on your device. Nothing is uploaded unless you choose to share it through another app.

What we do not do

• No account, sign-in, or email collection
• No advertising SDKs or cross-app tracking
• No analytics that identify you

Children

Tsumige is not directed at children under 13 and does not knowingly collect data from them.

Changes and contact

We will update this page if the policy changes. Questions: miinoki.mokomoko@gmail.com.
