Check-in Photographer (checkin-App) privacy

Applies to the Check-in Photographer mobile app (repository name checkin-App): a store app for iOS and Android in which you prove you visited a spot in Hong Kong with a location check-in and a photo. The app’s Privacy and Terms screens link here.

This service is operated by llab08, Hong Kong, and these terms are governed by the laws of Hong Kong. The section below explains this product’s data handling and current availability.

Rewards are unavailable. Check-ins are switched on for internal testing only; the app is not public. Merchant onboarding, offers and vouchers are not open.

Summary

The app handles location check-ins with photos. Your account uses our own authentication server; check-in photos are kept in private storage on our own server. There is no advertising. Merchant accounts, offers and vouchers are not open: none exist and none are issued in the current version.

Check-ins

When you check in, the app sends your device’s location fix (coordinates and accuracy), the spot you chose, the time, and the proof photo you take inside the app. The server checks that the fix lies within the spot’s area and that you have not already checked in there in the last 24 hours, then stores the check-in with the photo. Photos are used only to validate the check-in; they are stored in a private bucket on our own storage server and are not shown to other users or merchants.

Account

You sign in with Google or Apple through our own authentication server at supabase.llab08.com. We receive the name, e-mail address and avatar the provider shares with us; we never see a password. The same sign-in identity is shared with other llab08 products that use this server.

Merchants, offers and vouchers — not open

There is no way to register as a merchant and no way to publish an offer, so no voucher can be issued: the app holds no offer or voucher data for you, and none of it reaches anyone. When rewards open, merchants would register an account (name, organisation, location) and publish offers tied to spots; when a check-in is approved, matching vouchers would be issued to your account and we would keep each voucher’s code, status and redemption time so a merchant can redeem it once; a voucher would be an offer made by the merchant named on it. None of that happens today, and this section is updated before any of it does.

Spots and events

Spots and cultural events come from Hong Kong open data (tourist attractions, LCSD venues and events, AFCD visitor centres). Requests for this data are made by our server, not by your device. No merchant-supplied spot exists, because there are no merchants.

No ads, no analytics

The app shows no advertising and, as of the date below, loads no analytics or other third-party tracking. Error monitoring may use Sentry when it is configured; if a future version adds either advertising or analytics, this section is updated first.

Deleting your account

Profile → Delete Account removes your Check-in Photographer account, check-ins, proof photos and vouchers. Your shared llab08 sign-in identity and data in other llab08 products remain, so those products keep working. If you signed in with Apple, you must confirm with Apple first and we ask Apple to revoke Check-in Photographer’s access before deletion; if that fails, nothing is deleted. A new Check-in Photographer account cannot be created with the same llab08 sign-in, Apple or Google account, or e-mail address for two years. During that time we keep only keyed one-way hashes of those identifiers, not the identifiers themselves; the hashes are used only for this product’s block and are erased automatically after two years. To erase the remaining shared sign-in across products, write to hello@llab08.com.

Hosting and retention

The API, database, authentication and private photo storage are hosted on our own server. Check-ins and photos stay with your account until you delete it as described above. The two-year keyed hashes stay for the stated block period; the shared sign-in follows the company-wide retention and erasure information.

Children

The app is not directed at children under 13 and does not knowingly collect personal data from them.
