CHAIT Privacy Policy

Core principles

This Privacy Policy takes effect on 2026.09.26.

As a rule, CHAIT does not automatically sync your complete personal vehicle-management history to CHAIT servers. Server processing is used only where connected services require it, including sign-in, Owner Lounge, reports, security, operational diagnostics and minimal usage statistics, and external information lookups.

The app and service are operated as CHAIT. Requests to access, correct, or delete personal information can be sent to chaithelp@gmail.com.

Information stored on your device

• Vehicle name, manufacturer, model, model year, mileage, fuel type, fuel efficiency, vehicle category, and vehicle photos
• Service, fuel, wash, tuning, accident, vehicle expense, trip records, and notes
• Schedules, consumable status, notification read status, theme, usage mode, recent views, and saved posts
• On-device file paths or app-internal files for receipts, supporting photos, and before-and-after photos selected by you
• Information that may be lost without a separate backup if the app or app data is deleted or the device is changed

Information processed on servers

• Account identifiers, email addresses, profile information, and sign-in sessions provided through Kakao, Google, or Apple sign-in
• Owner Lounge posts, public Share Card information, comments, recommendations, saved posts, reports, and author identifiers
• Minimum request records needed for service security, error investigation, and prevention of duplicate posts or spam
• Operational diagnostics and minimal usage statistics used to maintain app reliability and understand daily usage
• Store purchase status required to verify subscriptions and restore purchases
• Signing in does not automatically upload your complete personal vehicle history to a server.

How permissions are used

• Location: used for current-location weather and nearby fuel-station searches; it is not used for continuous tracking.
• Smart Fuel sends your current coordinates to CHAIT's server and Opinet. It stores a location rounded to an approximately 100 m grid as a shared lookup cache key, without linking it to an account or vehicle or keeping a travel history. Results are reused for 30 minutes (5 minutes when empty); expired cache entries are cleaned up afterward.
• Photos and camera: used when you choose or take vehicle, receipt, accident, or service evidence photos.
• Notifications: used to show schedule and consumable reminders, and can be denied or disabled in device settings.
• Features that do not require a denied permission, such as vehicle records, remain available.

Operational diagnostics and minimal usage statistics

• Operational diagnostics and minimal usage statistics apply beginning with CHAIT 1.1.0.
• CHAIT processes only app-open counts; counts of records created, updated, and deleted; record category (maintenance, fuel, wash, tuning, vehicle expense, accident or repair, or trip); app version and build number; iOS or Android; and predefined error types and failure stages.
• These operational events do not contain amounts, notes, photos, receipts, places or coordinates, license plates, names or email addresses, user, account, vehicle, or record IDs, raw error messages, or stack traces.
• Usage events are aggregated as daily counts. They are not used to build individual activity histories or calculate unique users.
• CHAIT verifies that a request comes from a signed-in session to prevent abuse, but the account ID is not stored with the event. A random event ID is used only to prevent duplicate submissions.
• Operational diagnostics and usage data are retained only as needed for diagnosis and aggregate reporting, and are deleted when no longer required for those purposes.

External services and disclosures

• Supabase: sign-in sessions, profiles, Owner Lounge, reports and blocks, push tokens, PLUS server verification, operational diagnostics, and minimal usage statistics
• Kakao, Google, and Apple: social sign-in authentication chosen by the user
• Apple App Store and Google Play: CHAIT PLUS payments, subscription status, and purchase restoration
• RevenueCat: CHAIT PLUS products, purchases and restoration, subscription status, and entitlement verification using a service-specific identifier issued by the server instead of the CHAIT account ID
• Google Mobile Ads (AdMob): banner and interstitial ads for free users, including ad delivery, measurement, security, and fraud prevention
• Expo Push Service, Apple Push Notification service (APNs), and Firebase Cloud Messaging (FCM): push tokens, platform, and app-project information used to deliver notifications you allow
• Open-Meteo: current-location weather information
• Opinet: nearby fuel-station and fuel-price information, requested through CHAIT servers so the Opinet key is not stored in the app
• Google Maps Platform and Apple Maps: map area and location coordinates may be processed to display the in-app Smart Fuel map. When you choose to open directions, the start point and destination may be sent to the selected map app.

Advertising and consent controls

CHAIT uses the Google Mobile Ads (AdMob) SDK to provide ads to free users. CHAIT does not request or display ads for PLUS users.

For ad delivery, measurement, analytics, security, and fraud prevention, the Google Mobile Ads SDK may automatically process or share with Google an IP address (which may be used to estimate approximate location), app and ad interactions such as launches, taps, ads, and video views, diagnostics such as app launch time, hang rate, and energy use, and device or app identifiers permitted by the operating system, user settings, and consent choices.

CHAIT does not directly add vehicle details, service records, photos, search terms, email addresses, or custom targeting information to ad requests. On iOS, CHAIT currently does not request ATT permission or access IDFA.

In regions where consent is required, including the EEA, United Kingdom, and Switzerland, CHAIT provides required notices and choices through Google’s certified User Messaging Platform (UMP) and initializes the advertising SDK only when ad requests are permitted. CHAIT requests only non-personalized ads; depending on your choices and applicable law, non-personalized or limited ads may be served, or no ads may be served.

In regions where consent is not required, the European regulations message may not appear, and applicable local law and device or account advertising settings apply. When available, you can review or change consent choices through the privacy options in the app’s privacy settings.

For more information about Google’s advertising data practices, see the Google Privacy Policy (https://policies.google.com/privacy) and Google advertising policies (https://policies.google.com/technologies/ads).

Retention and deletion

• Local records may remain on your device until you delete them in the app, clear app data, or delete the app.
• Owner Lounge posts, comments, recommendations, and reports are linked to your account and kept on servers until handled following a deletion request or operational need.
• When you request account deletion, server data linked to your account is deleted. Information required by law or needed for disputes, security, or abuse prevention may be stored separately for the necessary period.
• CHAIT cannot remotely delete backup files that you store yourself.
• Send account withdrawal and server-data deletion requests to chaithelp@gmail.com.

Your rights and contact

• You may request access to, correction or deletion of, or restriction of processing of your information.
• You can view, edit, and delete local records directly through the app’s vehicle, record, schedule, and consumable-management features.
• For Owner Lounge posts and comments, please first use the available edit or delete controls.
• For server accounts, posts, or privacy requests you cannot handle directly, contact chaithelp@gmail.com.
• If you need further relief, you may contact an official privacy infringement or dispute-resolution authority in your jurisdiction.

CHAIT POINT and Reward PLUS

• CHAIT POINT is tied to your account and managed through a server-side ledger. CHAIT processes your available balance, earning and spending reasons, unique transaction keys, creation times, the account’s reward time zone, and duplicate-prevention status.
• Reward PLUS passes are linked to the account with their product, POINT cost, held or used status, activation date, and expiry date. The available products are a 15-day pass for 390P and a 30-day pass for 780P.
• POINT and Reward PLUS cannot be converted to cash or transferred to another account.
• CHAIT does not newly upload original vehicle, service, fuel, or wash records—or their amounts, notes, photos, or locations—to award POINT.

Rewarded-ad completion verification

• When a FREE user completes a rewarded ad, CHAIT awards the stated POINT only after checking Google AdMob server-side verification (SSV).
• Verification processes the ad network and ad unit, ad transaction ID, reward item and amount, completion time, a one-time random verification token, and signature-verification information.
• No POINT is awarded when an ad is not completed or verification fails, and the same ad transaction cannot be rewarded twice.
• The verification token contains no email address or vehicle record, and CHAIT does not send the CHAIT account ID to Google as the ad-verification user ID.

Data minimization after account deletion

• After account deletion is confirmed complete, CHAIT removes the original email address, original Auth user ID, free-text reason, raw administrator note, and POINT or PLUS account-linking identifiers from the retained deletion history.
• CHAIT may retain only the receipt number, request and completion times, final status, sign-in provider, consent-notice version and required consent flags, and—where needed—an irreversible verification hash for operations and dispute handling.
• This minimization applies only after actual deletion completes. It does not apply to pending requests or requests cancelled by the user.
