Perio Support

Last updated: October 18, 2026

Developed by Donguk Oh and Suhee Kim.

Perio is operated by Donguk Oh, an individual. Contact perioapps.admin@gmail.com for help with your account, pantry, photo analysis or privacy requests.

Report a problem

Include your app version, Android or iOS version, what you were trying to do, the error message and when it happened (with your time zone). Include the account email only if needed for an account request. Remove personal details from screenshots. Never send your password, authentication tokens or payment information.

The email link opens your email app; nothing is sent until you send the message. If the link does not open, copy the address into your email app. We retain support emails, replies and attachments for 90 days after the inquiry is resolved, then delete them from our support mailbox. Email provider copies may remain under provider retention policies. This period applies to support correspondence, separately from your pantry data.

Sign-in and password help

Use Forgot Password on the login screen and check your inbox and spam folder. If your pantry cannot load, check your connection and retry. If you cannot access the account, contact support from its registered email address; we may need to verify ownership.

Photo analysis and saving

Photograph one food item and its expiry label clearly. Review and correct the extracted details before saving. Analysis can fail or reach a usage limit; use Home → + to add food manually. If saving times out, check your list first to see whether the food was saved before creating another entry.

Expiry reminders

Allow notifications in your device settings and reopen Perio to refresh reminders after changing time zones. Android battery and idle settings can delay reminders. Check the dates yourself: Perio does not determine whether food is safe to eat.

Delete your account or request data help

In the app, open My account → Delete account and confirm your identity using your password or the Google or Apple sign-in method offered in the app. If deletion remains pending, retry until completion is confirmed. If you cannot use the app, contact perioapps.admin@gmail.com with the subject “Perio account deletion” and your registered account email. A message is a request, not immediate deletion; ownership must be verified before action.

Account deletion removes live account and pantry data. Security records, cost records, provider logs and backups have exceptions explained in the Privacy Policy. Local photos are not erased by account deletion: clear app storage or uninstall Perio separately. Uninstalling alone does not delete the online account.
