Privacy Policy

Effective 2 October 2026

Lockcheck.online ("we") provides a service that checks the status of mobile phones by IMEI number. This policy explains how we collect and use your personal data under the Personal Data Protection Act B.E. 2562 (2019). This English version is provided for convenience. If it differs from the Thai version, the Thai version prevails. อ่านฉบับภาษาไทย

1. Information we collect

Account information when you sign in with Google: your email address, name and profile picture (we do not receive your password)
Check information: IMEI number, model, check result and time of the check
Credit information: your credit balance; records of top-ups, usage, credit refunds and credits received or transferred; and refund requests
Credit transfers from resellers: the sender, recipient, amount, time and the reseller's note (the recipient cannot see this note)
Technical usage data, such as IP address, for system security

2. Purposes

To provide the checking service, display results and keep a history for you to view
To manage credits and review refund requests
To maintain security and prevent misuse
To contact and assist you when you reach out to us

We do not sell personal data and do not use it for advertising.

3. Disclosure of information

We disclose information only as necessary to service providers that help us operate (system infrastructure, authentication and data sources used for checks), who are bound by confidentiality obligations, and when required by law or by a competent authority.

When a reseller searches using the email address you gave them so they can transfer credits to you, the system shows your name partially masked so the reseller can confirm they are transferring to the right person, and your email address will appear in that reseller's transfer history. Your credit history will show the name of the reseller who made the transfer.

The reseller directory page shows each reseller's name, country, photo and contact channels (as the reseller has agreed to display) to signed-in members. Reseller photos are loaded from an external image hosting service, which, as is normal when loading images, can see the viewer's IP address and browser information; none of your account information is sent with it. When you click Contact, you go directly to the reseller's channel, which is subject to that service's own policy.

4. Information from Google

Sign in with Google uses only your email address, name and profile picture to create and verify your account. Our backup app uses the administrator's Google Drive to store encrypted backup files and accesses only the files the app itself creates. It does not access the Google Drive of any user of the service.

Lockcheck.online's use and transfer of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

5. Data retention

We keep data for as long as your account is active, or for as long as necessary for the purposes above and as required by law.

Your check history and credit transactions are shown in your account for at least the most recent 2 months. Older records may be moved to encrypted archival storage to serve as financial records and for later audits. You can request a copy of your older records by email at the address below.

6. Cookies and browser storage

We use cookies and browser storage only where necessary to provide the service, namely to keep you signed in, to protect against use by automated programs, and to remember your display settings and checks in progress. If you disable them, the website will not work.

We do not use cookies for advertising or cross-site tracking. Visit statistics are collected in aggregate, without cookies and without identifying you. You can delete cookies and stored data in your browser settings, after which you will need to sign in again.

7. Security

We use appropriate measures to protect your data, including encryption and access restrictions.

8. Your rights

You have the right to request access to, a copy of, correction of, deletion of, or restriction of your personal data, or to object to its processing, and to file a complaint with the Office of the Personal Data Protection Committee. To exercise your rights or to request account deletion, contact us by email at the address below.

9. Changes to this policy

If we make significant changes, we will update the effective date above and announce them on the website.
