Privacy Policy

Tabful is developed by ARTH, a studio operated by Nash Enterprises, Coimbatore, India (“we,” “us,” “our”). This policy explains what information Tabful collects, how it's used, and what choices you have. It applies to the Tabful Android app available on Google Play.

If you have questions about this policy, contact us at avinash@nashenterprises.in.

The short version

As of this version of Tabful, the app does not have a backend server. Everything you enter — groups, expenses, balances, friends — stays on your device. We don't receive it, store it on our servers, or share it with anyone, because there is currently no connection between the app and any server of ours. There is one exception: the optional Timeline feature (see below) is also entirely on-device, but it is designed so that you can choose to send its contents to yourself by email when you delete your account — that email is sent from your device using your own phone's mail app, not by us.

This policy is written to stay accurate as Tabful adds real functionality over time (an account system, cloud sync, and eventually the paid features described in-app). Where that's true, we say so below, and we commit to updating this policy — with a visible “last updated” date change — before or at the same time any new data collection actually ships, not after.

Information Tabful collects today

None. In the current build:

No account system is active. The login screen (Google, mobile number, or email + password) is part of the app's interface, but none of these options currently authenticate you or transmit anything you type into them anywhere. They are a preview of a feature that isn't wired up yet.
No expense or group data leaves your device. Everything you see — groups, balances, expense line items, friend profiles — is either built-in sample data or local state held in the app while it's open. We have no server to send it to.
No analytics. Tabful does not currently use any analytics SDK (for example Firebase Analytics or similar tools), so we don't receive usage statistics, crash reports, or device identifiers from your use of the app.
No advertising. Tabful does not currently show ads or use an advertising SDK, so no advertising identifier is collected.
No location, camera roll, or contacts access is used to collect data about you. If the app requests camera access, it's solely to scan a QR invite code locally on your device — no image or scan result is sent anywhere by us.

The Timeline feature, specifically

Tabful includes an optional feature called Timeline: a permanent, on-device, password-protected, append-only log of account-related events (such as joining a group or adding an expense). A few things worth being precise about, since this is the most privacy-sensitive feature in the app today:

Timeline is opt-in — you're asked about it at login and can toggle it in Settings, with a clear warning both times.
Timeline data is stored only on your device, protected by a password you set that is deliberately separate from any future account login password.
Nothing in the Timeline can be edited or deleted through the app — it's append-only by design, up until account deletion.
If you delete your account, Tabful genuinely emails your full Timeline history to your registered email address (via your phone's own mail app — a “mailto” handoff, not a server-side email we send) before erasing the local Timeline data for real. We don't see or retain a copy of that email ourselves.

CSV export

Tabful can export a group's expense history as a real CSV file, which you can then share, save, or send using your phone's normal share sheet. That export happens entirely on your device — we do not receive a copy of any file you export, and where it ends up after you tap “share” is entirely your choice (your own cloud drive, email, messaging app, etc.), governed by that destination's own privacy practices, not ours.

Children's privacy

Tabful is not directed at children and we do not knowingly collect information from children. Since the app currently collects no information at all from any user, this is easy to state plainly today; we'll revisit this section with age-appropriate detail once any account or data-collection feature ships.

Changes to this policy

Tabful is early — an account system, cloud sync between devices, and the paid features described in the app's “Go Pro” screen (currently a preview, not a working purchase flow) are all planned but not yet built. The moment any of those features starts collecting, storing, or transmitting information about you, we will update this policy before or alongside that release to describe exactly what's collected, why, how long it's kept, and who (if anyone) it's shared with — rather than leaving this “we don't collect anything” version live once it's no longer true. Check the “Last updated” date at the top of this page; material changes will also be reflected in the app's release notes.
