Momo is made by Yichang Yangyu Weilian Technology Co., Ltd. We built it so your habit data stays with you.
We do not collect any personal data. The app has no account, no analytics and no advertising. We have no server that receives your information.
Your questionnaire answers, check-ins, rest days, praise notes and any video messages you record are stored only on your device (and in your own iCloud backup if you have it turned on). Deleting the app deletes this data.
Notifications are used only for the reminders you set. Camera and microphone are used only when you choose to record a message to yourself; the video never leaves your device.
The one-time purchase is handled by Apple. We do not receive your payment details.
Momo is not directed at children under 13 and does not knowingly collect data from anyone.
If this policy changes, we will update this page and the date above.
