KrubKa Privacy Policy
Last updated: 30 August 2026
KrubKa ("we", "us") is a translation service that translates messages between English and Thai through the LINE messaging platform, with a companion mobile app and operates a local-help marketplace. This policy explains what data we handle and why.
Data we collect
- LINE profile basics. Your LINE user ID and display name, provided by LINE when you interact with the KrubKa bot.
- Messages. Text messages and images you send to the bot in a 1:1 chat, and text messages sent in group chats the bot has been added to. We store message text and generated translations to operate the service. Image bytes are processed temporarily and discarded; we retain the resulting explanation, not the image itself.
- App account. If you sign in to the KrubKa app, we receive the account identifier and, when supplied by the provider, your name or verified email address from Apple, Google, or email sign-in.
- Subscription status. If you subscribe, Apple and our subscription provider (RevenueCat) tell us whether your subscription is active. We never see your payment details — payment is handled entirely by Apple.
- Usage data. Translation counts (used for monthly quotas) and technical logs needed to keep the service running.
- Marketplace location. When you post a local-help request, we store the province, district, address you confirm, and any map pin you choose. Exact addresses and pins are encrypted and shown only to you, administrators, and the helper you confirm. Device location is read only after you tap “Use my current location.”
- Website acquisition data. When you open a campaign link, we use a random first-party visit identifier that expires after 30 minutes to connect that landing to taps on the LINE or app-store links. We also record the campaign label, browser user agent, referring page, and event time. The identifier is not used across sites or connected to your LINE identity or app account.
How we use it
- To translate your messages. Message content is sent to third-party AI service providers to produce the translation.
- To operate free-tier quotas and subscriptions.
- To keep the service secure and diagnose problems.
- To measure whether our own campaign and website links are useful.
We do not sell your data and we do not show ads.
Group chats
When the KrubKa bot is added to a LINE group, text messages sent in that group are processed for translation. Anyone in the group can pause this at any time by typing /pause in the chat, and resume it with /resume. Removing the bot from the group stops all processing.
Who we share data with
- LINE — the messaging platform the bot runs on.
- AI service providers — receive message content to produce translations.
- RevenueCat and Apple — subscription management and billing.
- Google Maps Platform — address suggestions, place details, maps, and reverse geocoding when you use marketplace location tools. Google processes those requests under the Google Privacy Policy.
- Infrastructure providers — hosting for our servers and database.
Retention and deletion
We keep account, message, translation, usage, and operational records while you use the service. You can delete your account in the app. This immediately removes the account and data authored by LINE identities linked to it, and queues deletion of the corresponding RevenueCat customer record. Deleting the account does not cancel an Apple subscription; subscriptions must be cancelled separately in App Store settings. Service providers may retain limited records where required by their contracts, security duties, or applicable law.
Your rights
You can request a copy of your data or ask us to delete it at any time by contacting us.
Changes
If we change this policy we will update this page and the date above.
