How can we help?
Email hello@dailycalo.vn and we reply within one business day. A description with a screenshot, the app version (Me tab) and your account email helps us fix things faster. The app itself is currently in Vietnamese; the button names below are given in English, with the Vietnamese label in brackets where it helps.
Account
Didn’t get the 6-digit code? Check your Spam / Promotions folder, wait 60 seconds and tap “Resend code” (Gửi lại mã). Each code works once and expires shortly.
Forgot your password? On the sign-in screen enter your email, tap “Forgot password?” (Quên mật khẩu?), enter the emailed code and set a new password. When signed in: Me → Change password.
Signed in on someone else’s phone? Me → Sign out other devices.
How do I delete my account? Me → Delete account → Delete permanently. Your account, logs, photos, clips and messages are deleted immediately and cannot be recovered. You can also delete it from the bottom of the first-run profile screen.
Download my data? Me → Export all data (JSON) or Export food log (CSV, opens in Excel / Numbers).
Calories, AI and targets
Are AI calorie estimates accurate? Close enough to follow daily trends, but still estimates. For oily dishes, sauces or hard-to-judge portions, adjust the grams before saving; every AI number can be edited.
How is my calorie target calculated? BMR via the Mifflin-St Jeor formula from sex, age, height and weight (or BMR from an InBody printout if you have one), multiplied by an activity factor to get TDEE, then adjusted for your goal. Edit it in Me → Energy card.
Don’t want to send data to AI? Tap “Don’t agree” (Không đồng ý) when asked, or Me → Withdraw AI consent. Manual logging keeps working.
Does DailyCalo replace a doctor? No. Figures and David’s answers are for reference only. If you have a medical condition or are pregnant or breastfeeding, talk to a doctor before changing your diet.
Community and PTs
Seeing bad content or being harassed? Tap the flag icon to report a post or comment; open the person’s profile or chat to report or block them. We act on reports within 24 hours.
What can a PT see? Only after you connect and the PT accepts can they view your logs and metrics (read-only); they cannot see your David chats. Disconnect and their access ends immediately.
Payments, cancellations, refunds? Payments go through MoMo. Cancel at least 12 hours before a session to get it back. For payment issues, email us with the order code.
App
Light / dark mode? Me → Appearance. The app starts in light mode.
Phone running warm? Me → Options → turn off the glass effect.
Diary reminders? Me → Options → Diary reminders (12:30 and 20:00). If they won’t turn on, go to iPhone Settings → DailyCalo → Notifications.
