We may collect the following to provide the service:
• Account: email, nickname, profile photo
• Social login: identifiers, email, and/or name provided by Apple, Google, Kakao (or LINE), depending on the provider and your choices. If you use Apple’s Hide My Email, the private relay address may also be used to identify your account
• Location: GPS for posts and map display
• Content: posts, postcards, map pins, comments, likes, and other content you create
• Device notifications: push token if you allow notifications
• Photos/media: images you pick or capture for posts, postcards, or profile
We use data to share live field updates, personal map records, postcard storage, comments/likes/notifications, authentication and support, and service improvement.
You can sign in with Apple, Google, Kakao (or LINE). We receive account information within the scope you approve and use it for registration, sign-in, and account linking. We do not store those providers’ passwords; their policies also apply.
Posts, postcards, and profile photos may require access to your photo library or camera. You can change permissions in device settings anytime. Declining only limits those features.
Location is used to verify posts within 200m and show pins on the map. You can change permission in device settings anytime.
We may store a device push token to send alerts such as comment notifications. You can turn notifications off in device or app settings; we then stop using the token for that purpose.
Field posts hide from the map after 1 hour and are deleted after 24 hours. Postcards, pins, and profile data are kept until account deletion, when related data is permanently removed (except where retention is required by law).
We do not sell or rent your personal information. We use infrastructure such as Supabase for hosting and auth, Google Firebase (FCM) for push delivery where applicable, and Apple, Google, Kakao (or LINE) for sign-in. Their privacy practices also apply to data they process.
To operate the service, we may store and process personal information on overseas cloud infrastructure. Where Korean law applies, this is done as processing entrustment/storage necessary to perform the contract with you, and disclosed in this Privacy Policy (Personal Information Protection Act Art. 28-8(1)(3)).
