Privacy Policy

Last updated: 14 September 2026

In short: Bayar stores the expense records you enter so you can see them across your devices. We do not show ads, we do not use analytics or tracking, and we do not sell your data.

Who we are

Bayar (the Android app, the iOS app and the web dashboard at bayar.npj.app) is operated by Nebula Technology, Surabaya, East Java, Indonesia. For any privacy question, contact hello@npj.app.

What we collect

We do not collect your location, contacts, or advertising identifiers. Fingerprint and face unlock are handled entirely by your phone's operating system, and we never receive biometric data.

How we use it

Who can see your data

We do not sell or rent your personal data, and we do not share it for advertising.

Data on your device

The apps keep a local copy of your records so they work offline. Sign-in tokens are stored in the Android Keystore or iOS Keychain. The web dashboard uses a sign-in cookie, and stores your username and selected workspace in your browser's local storage. There are no tracking or advertising cookies. Signing out or uninstalling the app removes local data.

Security

All data is sent over encrypted HTTPS connections. PINs are stored only as hashes, and each workspace's records are isolated from other workspaces in the database.

How long we keep it

We keep your data while your account is active. When you delete your account, your account details and every workspace that only you belong to, with all its expenses, are deleted immediately and permanently. Workspaces shared with other people stay available to them.

Deleting your account and your rights

You can delete your account yourself at any time in the app under Settings → Delete account. You will be asked to confirm with your PIN.

You can also ask us to access, correct, export or delete your data at any time by emailing hello@npj.app from the email address linked to your account, or with your username. We respond within 30 days. These rights are provided in line with Indonesia's Personal Data Protection Law (Law No. 27 of 2022).

Children

Bayar is not intended for children under 13, and we do not knowingly collect their data.

Changes to this policy

If we change this policy, we will update the date above. For significant changes, we will also let you know in the app.
