Last updated: 31 July 2026

Smart Sell ("the app") is a shop-billing tool for small retailers. This page explains what information the app handles, how it's stored, and who it's shared with.

What the app stores

To run your shop, the app keeps records you enter yourself:

Data	Why
Shop name, address, phone	Shown on printed/shared receipts
Product list, prices, stock counts	Billing and inventory tracking
Sales history	Receipts and sales reports
Customer name, phone number	Due (credit) ledger per customer
Customer photo (optional)	Helps you recognize the customer in the due list — you choose whether to add one
Due/payment records	Track what a customer owes and what they've paid back

All of this is entered by you, the shop owner — the app does not collect data about your customers from any outside source.

Where it's stored

By default, everything above is stored only on your phone, in the app's local storage. It is not sent anywhere unless you turn on cloud backup.

Cloud backup (optional, requires Google Sign-In)

If you sign in with your Google account, the app uploads a backup copy of your shop data (the items in the table above) to Google Firebase, tied to your Google account. This is used only to:

Restore your data if you reinstall the app or switch phones
Keep a safety copy in case your phone is lost or damaged

This backup is not shared with other users, not used for advertising, and not sold to any third party. Your Google account is used solely to identify which backup belongs to you — the app does not read your email, contacts, or other Google data beyond your basic account identifier.

Camera & photos

The app asks for camera access for two features, both of which you choose to use:

Barcode scanning — the camera reads a barcode to look up a product; no image is saved.
Customer photo — if you choose to attach a photo to a customer's due record, it's stored the same way as the rest of your shop data (locally, and in your cloud backup if enabled).

Bluetooth

Used only to connect to a thermal receipt printer you pair yourself. The app does not scan for or connect to any other Bluetooth device.

The app does not currently show ads. Your shop data is never sold or shared with data brokers or marketers — that applies whether or not ads are added later. If ads are introduced in a future update, this policy will be updated to describe what's shown and any data involved before that update reaches you.

Your choices

You can use the app fully without ever signing in — cloud backup is optional.
You can delete individual products, customers, or due records at any time inside the app.
To delete your cloud backup entirely, contact us at the email below.
Uninstalling the app removes all data stored locally on that device.

Children's privacy

Smart Sell is a business tool intended for shop owners and staff, not for children, and is not directed at children.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new "last updated" date.
