Privacy policy

Effective 14 November 2026.

Who we are

Nela Lekka is published on Google Play by Sangachadwam, an independent studio in India. Contact: support@sangachadwam.in.

What the app keeps, and where

The app keeps what you type: the names of the people you pay and what for, quantities, rates and their dates, salaries, leave rules, the days you mark, payments, advances, your away dates, closed bills and your settings. It is stored only in the app’s private storage on your phone, with a few dated copies in the same private storage so a bad update can be undone.

We never ask for your phone number, contacts, location, photos, camera or microphone. Names are typed by you; the app never reads your contacts.

Every bill is worked out on the phone each time; nothing is sent anywhere to work it out.

Permissions the app asks for

The app shows no permission prompt. Internet and network state: only to load the ad, and to skip it when you are offline. Advertising ID: used by the ad SDK (see Ads below). Vibration: touch feedback.

Nothing else: no notifications, contacts, photos, files, location, camera, microphone, phone or exact alarms. The backup folder you choose is opened through Android’s own file picker, which needs no storage permission.

Internet use

The account works fully offline. The app uses the internet only to show the ad and for Google Play services such as app updates.

We run no analytics or crash-reporting service in the app.

Ads

Nela Lekka shows one banner ad from Google AdMob at the bottom of the bill screen, from your second week of use. Never while you mark a day, never on the first run, and never when you are offline.

To show ads, the Google Mobile Ads SDK collects your device’s advertising ID, device information, your approximate location from your IP address, app interactions (such as an ad being shown or tapped) and diagnostics. Google receives this data. It does not include your account, names or amounts.

Ads are not personalised unless you agree in the consent form. We block ad categories for loans, credit, finance and get-rich-quick offers.

You can reset or delete your advertising ID in Android settings at any time.

Backups

If you choose a folder, the app saves a dated backup file there by itself, each week and when you close a month. You can also save one at any time. The file stays where you put it; we never receive it. Anyone who has the file can read it, so keep it somewhere private.

Android’s own backup may copy the app’s data to your Google account, as it does for most apps, so it can come back on a new phone. This is controlled by your Google account settings, not by us.

Sharing a bill

When you tap Share, the app makes a text or a picture of that one bill and hands it to the app you pick, such as WhatsApp. That app’s own privacy policy then applies.

Notifications

The app sends no notifications.

This website

This website sets no cookies and runs no analytics or scripts. It is served by Cloudflare, which keeps standard server logs (such as your IP address) for security.

Children

The app is meant for adults who run a household. It is not directed at children.

Deleting your data

Everything is on your phone, so you delete it yourself: one day, one person, or everything. To remove everything at once, uninstall the app or clear its storage in Android settings. Backup files are deleted where you saved them, and Android’s backup is deleted from your Google account. You can reset your advertising ID in Android settings.
