PRIVACY POLICY

Lịch Vạn Niên app as a Free app. This SERVICE is provided

by Tiện Ích Việt at no cost and is intended for use as is.

This page is used to inform visitors regarding my policies with the

collection, use, and disclosure of Personal Information if anyone

decided to use my Service.

If you choose to use my Service, then you agree to the collection and

use of information in relation to this policy. The Personal

Information that I collect is used for providing and improving the

Service. I will not use or share your information with anyone except

as described in this Privacy Policy.

The terms used in this Privacy Policy have the same meanings as in our

Terms and Conditions, which is accessible at Lịch Vạn Niên unless

otherwise defined in this Privacy Policy.

Information Collection and Use

For a better experience, while using our Service, I may require you to

provide us with certain personally identifiable information. The

information that I request will be retained on your device and is not

collected by me in any way.

The app does use third party services that may collect information

used to identify you.

Google Play Services

Google Sign-In

Google Drive API

Google Account Sign-In and Google Drive Sync

The app offers an optional feature to sync your personal notes

("Ghi chú") with your Google Account, so they can be automatically

restored if you reinstall the app or switch devices.

If you choose to sign in with Google, the app accesses:

- Your Google email address and profile name, solely to show which

  account you are signed in with.

- The "drive.appdata" scope of Google Drive: a hidden, app-specific

  folder in your Google Drive. This folder is not visible in your

  Google Drive interface and the app cannot access any other files,

  folders, or data in your Google Drive.

Within this hidden folder, the app stores a single backup file

containing the notes you created inside the app (title, date, time,

category, and reminder settings). This data is used exclusively to

restore your notes on this or another device signed in with the same

Google Account. It is not shared with QTI, with any third party, or

used for any purpose other than backup and restore.

You can revoke this access at any time at

https://myaccount.google.com/permissions, which immediately deletes

the app's access to your Google Account and to this backup folder.

Uninstalling the app removes the notes stored locally on that device.

Log Data

I want to inform you that whenever you use my Service, in a case of an

error in the app I collect data and information (through third party

products) on your phone called Log Data. This Log Data may include

information such as your device Internet Protocol ("IP") address,

device name, operating system version, the configuration of the app

when utilizing my Service, the time and date of your use of the

Service, and other statistics.

Cookies

Cookies are files with a small amount of data that are commonly used

as anonymous unique identifiers. These are sent to your browser from

the websites that you visit and are stored on your device's internal

memory.

This Service does not use these "cookies" explicitly. However, the app

may use third party code and libraries that use "cookies" to collect

information and improve their services. You have the option to either

accept or refuse these cookies and know when a cookie is being sent to

your device. If you choose to refuse our cookies, you may not be able

to use some portions of this Service.

Service Providers

I may employ third-party companies and individuals due to the

following reasons:

To facilitate our Service;

To provide the Service on our behalf;

To perform Service-related services; or

To assist us in analyzing how our Service is used.

I want to inform users of this Service that these third parties have

access to your Personal Information. The reason is to perform the

tasks assigned to them on our behalf. However, they are obligated not

to disclose or use the information for any other purpose.

Security

I value your trust in providing us your Personal Information, thus we

are striving to use commercially acceptable means of protecting it.

But remember that no method of transmission over the internet, or

method of electronic storage is 100% secure and reliable, and I cannot

guarantee its absolute security.

Links to Other Sites

This Service may contain links to other sites. If you click on a

third-party link, you will be directed to that site. Note that these

external sites are not operated by me. Therefore, I strongly advise

you to review the Privacy Policy of these websites. I have no control

over and assume no responsibility for the content, privacy policies,

or practices of any third-party sites or services.

Children's Privacy

These Services do not address anyone under the age of 13. I do not

knowingly collect personally identifiable information from children

under 13 years of age. In the case I discover that a child under 13

has provided me with personal information, I immediately delete this

from our servers. If you are a parent or guardian and you are aware

that your child has provided us with personal information, please

contact me so that I will be able to do necessary actions.

Changes to This Privacy Policy

I may update our Privacy Policy from time to time. Thus, you are

advised to review this page periodically for any changes. I will

notify you of any changes by posting the new Privacy Policy on this

page.

This policy is effective as of 2026-08-03
