tsuuchi is a small iOS app for sharing light daily prompt answers with close friends.
We collect the Sign in with Apple user identifier, display name, username, bio, icon, optional birth date, profile visibility flag, follow relationship state, session information, answers to daily prompts, mood-tagged comments on those answers, and in-app notification records created by follows and comments.
We use this data to sign you in, store your answer history, generate personal AI insights and a mood profile from your recent answers, notify you when another user follows you or comments on your answer, and show recent answers to signed-in users who are not in a block relationship with you. Mood-tagged comments posted on an answer are visible to any signed-in user who opens that answer. Your birth date is visible only to you; other users can see only the derived zodiac sign. A mood profile and past answers are visible to signed-in users unless either account has blocked the other. We also show a seven-day service-wide mood trend that counts only each user's latest answer per day and does not include names or answer text.
tsuuchi uses Cloudflare Workers and D1 to run the API and store app data. Only your own relevant comments are processed by Cloudflare Workers AI to generate personal insights and mood-profile boosters or drainers. Cloudflare may also process request metadata and operational logs so we can keep the service reliable and investigate errors.
Account data, answer history, mood-tagged comments, in-app notification records, and saved AI analyses are kept while your account exists. Recent answers with a short text appear on Home for 24 hours; past answers remain available from a profile to signed-in users unless either account has blocked the other. A comment thread and related comment notification remain with the original answer until the answer or relevant account is deleted.
We do not sell personal data, run ads, track users across apps or websites, sync contacts, or publish public timelines.
You can delete your account from inside the app. Deletion marks your account as deleted, revokes active sessions, hides your profile and shared answers from other users, and deletes your saved AI insights, mood-profile analysis, mood-tagged comments, and related in-app notification records.
