Easy to fix. Here's what to do:

2. 2Tap Restore purchases.
3. 3Make sure the iPhone is signed in to the App Store with the Apple Account you paid with.

Yes. Searching the food database and logging by hand is free, with no card needed. AI photo scans and barcode scans need Calkub Premium.

• You'll find it under + → Food database: search, Manual Add or Voice Log.
• Any introductory offer, and the price after it, is shown in the app before you subscribe.
• If your subscription ends, everything you've logged stays on your iPhone.

• Yearly: ฿999
• Monthly: ฿149

Those are Thai App Store prices. Elsewhere you'll see your App Store's own currency, and it's always billed through Apple. Any introductory offer is shown in the app before you subscribe.

Subscriptions are managed by Apple, so we can't cancel one for you. Two ways to do it:

• iPhone: Settings → tap your name → Subscriptions → Calkub → Cancel Subscription.
• In the app: Profile tab → Manage Subscription.

Apple bills every Calkub subscription and decides refunds under Apple's terms. We never see your payment details, so we can't issue one ourselves.

Every figure is an estimate, and the app shows the range it could fall in. A few things help a lot:

• Good light makes a big difference. Daylight or a bright room works best.
• Get the whole plate in frame, close enough that the food fills it.
• Type the dish name or a hint, such as “less sweet” or “no coconut milk”.
• Tap Fix result to pick the right dish or adjust the numbers before saving.

• 20: a lab study of real Bangkok delivery portions.
• 16: Thai on-pack nutrition labels.
• 14: computed from fully documented component weights, and 2 from USDA data.

Another 149 international dishes come from USDA FNDDS, including Japanese and Korean dishes such as udon, gyudon, bulgogi and kimbap.

The full citation for every source is in our Terms of Use, and in the app under Profile › Support & Legal › Nutrition Data Sources.

• Overweight from 23 (international: 25).
• Obese from 25 (international: 30).

No. Calkub works fully without an account. Sign in with Apple is optional, and we ask Apple for your name only, never your email.

• Meal photos are never uploaded to iCloud.

1. 1Delete the app to delete the data on your iPhone.
2. 2If you used iCloud backup: Settings → your name → iCloud → Manage Storage → Calkub.
