Local by default
Drink history, goals, cup settings, and reminders stay on your iPhone. Optional sign-in does not automatically upload those records.
Local-first hydration tracking
Your cup.
Your rhythm.
MyCup turns the cup you already use into a simple daily hydration habit. Log in one tap, follow your progress, use local reminders, and optionally create a personalized cup image from a photo.
Fast daily logging
Use your configured cup amount, edit today's entries, review trends, and log from the Home Screen widget.
Optional AI cup
With explicit consent, MyCup can turn a real cup photo into a personalized cup image. The default cup remains fully usable without AI.
默认保存在本机
饮水记录、目标、水杯设置和提醒保存在 iPhone。本地数据不会因为可选登录而自动上传。
快速日常记录
按当前杯量一键记录，修改今日明细，查看趋势，并可通过主屏幕小组件记录。
可选 AI 水杯
经明确同意后，可把真实水杯照片生成专属水杯形象。不使用 AI 也能完整使用默认杯和本地记录。
AI transparency
Built with a small data footprint.
Original photos are processed in memory and are not written to MyCup server storage. Generated images are retained for about one hour for delivery and automated cleanup runs every five minutes. Usage and access logs have defined retention limits. Read the full details before choosing a photo.
AI 透明说明
尽量减少服务端数据。
原始照片只在内存中处理，不写入 MyCup 服务器磁盘。生成图片约保留 1 小时用于交付，系统每 5 分钟自动清理；额度与访问日志也有明确保留期限。选择照片前可以查看完整说明。
