CHAIT Terms of Service

Effective date and scope

These Terms apply to all features provided in the CHAIT app from 2026.09.22.

They cover the conditions for using vehicle records, schedules, reminders, the Maintenance Guide, Smart Fuel, Owner Lounge, document exports, backup and restore, and CHAIT PLUS.

Feature-specific notices, paid-product information, the Privacy Policy, Location-Based Services Terms, and Owner Lounge Policy also apply.

Accounts and sign-in

• You may sign in with Kakao, Google, or Apple. CHAIT does not store your password directly.
• The social sign-in provider authenticates you, while CHAIT uses the account identifier and session needed to connect the service.
• Using another person’s account or lending your authentication method is not permitted.
• Signing out does not automatically delete vehicle records, photos, or settings stored on the current device.

Vehicle records and reference information

• You are responsible for the accuracy of vehicle, service, fuel, wash, tuning, accident, vehicle-expense, and trip records you enter.
• The Maintenance Guide and Insights provide reference information and do not replace a repair shop’s diagnosis or estimate.
• Vehicle Reports and business-vehicle documents organize records entered by the user. They are supporting documents, not final evidence for tax, accounting, insurance, or legal decisions.
• For important decisions involving service, safety, accidents, taxes, or insurance, rely on the vehicle manual, official guidance, and qualified professionals.

CHAIT PLUS and payments

• Confirm the product name, price, term, and any free trial on the App Store or Google Play screen immediately before purchase.
• Canceling a subscription stops renewal from the next billing date. Access during an already paid period and refunds follow the store’s policy.
• CHAIT does not directly retain full payment details such as card numbers, bank account numbers, or payment passwords.
• Ending a subscription does not automatically delete existing local records, but access to PLUS-only features and additional vehicles may be limited.
• A backup file does not copy subscription entitlements or payment information.

Backups and local data

• Personal vehicle records are stored on your device by default, and you are responsible for keeping backup files.
• Without a separate backup, local records may be difficult to restore after app deletion, app-data reset, device loss, or device replacement.
• PLUS users can create encrypted backup files, and restoring a backup remains available on the free plan.
• You store backup files directly in a location you choose, such as iCloud, Google Drive, or a computer.
• CHAIT cannot store or recover your backup password, so you must manage it yourself.

Prohibited conduct and service restrictions

• False records, altered receipts, repetitive posting, recommendation manipulation, or comment spam
• Infringing another person’s privacy, copyright, trademark, or portrait rights
• Interfering with CHAIT’s normal operation or exploiting a security vulnerability
• Selling or bypass-sharing PLUS access, backup files, or accounts among multiple people
• Using the Owner Lounge for advertising, secondhand sales, recruitment, or directing users to outside contact

Withdrawal, deletion, and inquiries

• Local-record deletion and deletion of a server account or Owner Lounge data cover different data and locations.
• Deleting the app may remove data from the current device, but does not replace a request to delete a server account, post, or comment.
• After identity verification, an account deletion request removes server data linked to the account.
• For withdrawal, post deletion, privacy, or dispute inquiries you cannot handle directly, contact chaithelp@gmail.com.

CHAIT POINT and Reward PLUS passes

• CHAIT POINT is a service benefit recorded in your account ledger when the server verifies an in-app condition such as attendance, activity, or rewarded-ad completion.
• You can exchange 390P for one 15-day Reward PLUS pass or 780P for one 30-day Reward PLUS pass.
• A pass belongs to the account that exchanged it and is not issued as a code. Cash-out, refunds, resale, and transfer to another account are not supported.
• An exchanged pass does not start automatically. Its stated period starts when you choose to activate it.
• A Reward PLUS pass cannot be activated while Store PLUS purchased through the App Store or Google Play is active.

POINT verification and account deletion

• POINT balances and ledger entries are determined by the server; the app cannot choose an award amount.
• Rewarded-ad POINT is issued only after server verification. An incomplete, failed, altered, or replayed transaction earns no additional POINT.
• When account deletion is completed, remaining POINT, unused Reward PLUS passes, and any remaining active Reward PLUS period expire and cannot be restored, transferred, or refunded in cash.
• Store PLUS subscriptions in the App Store or Google Play are separate from CHAIT account deletion. You must manage cancellation and refunds separately through the applicable store.
