SnapCal 技术支持

Every item on the result screen is editable: tap a food to change its portion and all the numbers recalculate instantly, delete items that do not belong, and add anything missing with Add food.

For better results, shoot in good light, from above, with the whole plate in frame and nothing covering the staple foods. Items marked “estimated” come from the AI rather than the local nutrition table and may be further off.

If the same photo keeps coming out wrong, email it plus the result to support@capyka.com and we will use it to improve the recognition prompt.

The free plan includes 3 AI photo scans per day; once they are used you can scan again the next day.

Manual search logging, quick calorie entry, recent foods, copy-meal, the diary, weight tracking and insights are all unlimited. Pro simply removes the scan limit and unlocks deeper insights, full history and custom targets.

On iPhone: Settings → your name (Apple Account) → Subscriptions → SnapCal Pro → Cancel Subscription. You can also manage it from your App Store account page.

After cancelling you keep Pro features until the end of the period you already paid for, then the app returns to free-plan limits. Nothing you have logged is deleted.

Deleting the app does not cancel a subscription — please use the path above.

Apple collects the subscription fee, and Apple also handles refunds under their policies. Sign in at reportaproblem.apple.com with the Apple Account you purchased with and file a request for the relevant order.

We cannot see your payment details and cannot issue refunds ourselves, but if you need us to explain the circumstances, just write in.

Sign in with the same Apple Account and enable cloud sync to restore the latest successfully synced meal, weight and settings snapshot. Meal photos may remain only on the old device; an iCloud or computer device backup can also migrate local app data.

Check three things: (1) the Settings → Apple Health switch inside SnapCal is on and permission was granted; (2) the meals were logged after you granted permission (earlier entries are not back-filled); (3) you are looking under Browse → Dietary Energy in the Health app rather than the summary card.

If you tapped “Don’t Allow” before, re-enable write access in iOS Settings → Health → Data Access & Devices → SnapCal.

Clear local records from Settings → Privacy & Data. If you signed in, also use Delete account to remove the server account and synced data; uninstalling the app alone does not delete server data.

Samples already written to Apple Health stay there; delete them in the Health app or revoke SnapCal’s write access.

Only when you start a scan: that one photo is resized to at most 1280 pixels on the long edge, stripped of metadata such as capture time and location, and sent over HTTPS to a third-party intelligent recognition service to judge what the food is and how much it weighs. We do not store the image once the result returns.

Your original photo is never uploaded, and if you never tap scan, no photo leaves the phone at all.

Details are in section 4 of the privacy policy.

Email us. To help us pin it down quickly, please include:

• Device model and iOS version (Settings → General → About)
• App version (shown at the bottom of SnapCal’s settings screen)
• What you did before the problem and whether it happens every time
• Screenshots or a screen recording, if convenient
