Privacy Policy
NCMC Tracker is a free Android app that reads your NCMC card and shows your balance and rides. This policy explains what the app and this website do with your data. It is written in plain language.
Who we are
NCMC Tracker is an independent app. It is not affiliated with CMRL, NPCI, any metro operator or any bank.
For privacy questions, write to ncmc@prabhuls.me.
The app is free
The app is free to use. There is no subscription, no in-app payment and no account.
We do not ask for your name, phone number, email or payment details.
What the app reads from your card
When you tap your card, the app reads the card number, balance, expiry date and the ride and top-up records stored on the card. It needs this data to show your balance and history.
The app only reads the card. It cannot add money, change your balance, block a card or start a payment.
What stays on your phone
Your card details and ride history are stored only on your phone. Android backup and device transfer are turned off for this data. There is no login and no cloud sync.
We do not upload your card number, expiry date, balance, ride history, name, phone number or email.
If you uninstall the app, the data stored by the app is removed. You can also clear it from Android settings at any time.
Analytics, error logging and monitoring
The app may use analytics, error logging and monitoring tools from well-known providers such as Google. For example, it may use Firebase Analytics. These tools help us see how the app is used, find crashes and fix problems.
These providers may collect basic technical data. This can include your device model, Android version, app version, a random app instance ID, general location such as country or city, and app events such as opening a screen. The data is used in aggregate. It is not used to identify you.
These providers handle data under their own privacy policies. You can read Google's policy at https://policies.google.com/privacy.
The website
This website is a simple static site. It has no login, account area, contact form or advertising. We do not set cookies for advertising or tracking.
Our hosting provider may keep standard access logs. These can include your IP address, browser type and the pages you visit. The logs are used for security and reliability.
Sharing
We do not sell your personal data. We do not share it with advertisers.
Data may be shared with the service providers described above, or when the law requires it.
How long we keep data
Card data stays on your phone until you delete it or uninstall the app.
Analytics and log data are kept by the providers for the periods set out in their policies. If you email us, we keep the conversation only as long as needed to help you.
Security
We take reasonable steps to protect data. Your card data stays on your device.
No method of storage or transmission is fully secure, so we cannot promise complete security.
Your choices
The app does not collect personal data. All card data stays on your phone.
You can stop using the app at any time. Uninstall it or clear its storage in Android settings to remove the data stored by the app.
You can limit analytics through your device settings where Android offers them.
If you have questions about data held by analytics providers such as Google, you can manage your preferences through your Google account settings or by contacting us at ncmc@prabhuls.me.
Children
The app is meant for adults who use an NCMC card. It is not directed at children under 18, and we do not knowingly collect personal data from children.
If you think a child has shared data with us, contact us and we will delete it.
Changes to this policy
We may update this policy when the app changes. The new version will be posted on this page with a new date.
Please check this page now and then.
