Tillmint privacy policy

Last updated November 6, 2026. This policy covers the Android app Tillmint: Cash Register POS (com.tinyfair.tillmint) published by Tinyfair on Google Play.

The short version

The app works on your phone. We do not have accounts or servers, and we never receive your products, your sales or personal details. Data leaves your phone only for ads, purchases, crash reports and anonymous usage statistics (Google), for a small settings file the app downloads from our website, and when you yourself share a receipt or save a backup somewhere, as described below.

Data that stays on your phone

Products and sales
Your items, prices, photos, stock, sales, refunds and reports are saved in the app on your phone.
Store settings
Your store name, receipt lines, currency, tax and printer choices are saved on your phone.
Backups
A backup file is made only when you ask for it (or, with Pro, when you turn on daily auto-save to a folder you pick). You choose where it goes, such as your own Google Drive, and it is never sent to us.
Barcode scanning
The camera picture is read on your phone to find the barcode and is not saved or sent anywhere.
Purchases
Handled by Google Play; we never see your payment details.

Settings file from tinyfair.my.id

When it starts, the app downloads a small settings file from https://tinyfair.my.id/config/tillmint.json (the minimum app version and which ad formats may appear). The request sends no personal data and no identifier. Like any web request, our web host sees your IP address in its standard server logs; we do not use it to identify you or link it to anything else.

Backups and shared receipts

When you tap Back up now or share a receipt, Android shows its share sheet or file picker and you choose where the file goes, for example your own Google Drive, email or a folder on your phone. The file goes straight there under your own account and is never sent to us. Android Auto Backup may also include the app's data in your Google account backup if you have it turned on.

Ads (Google AdMob)

The free version shows ads from Google AdMob: banner ads on the History, Reports, Items and Settings screens, sometimes a full-screen ad at a natural break (never while you are selling, never in your first session), and a video ad only when you choose to watch one for 24 hours of Pro. There are no ads on the Sell, Pay and receipt screens, and no ad when the app opens. Ad content is limited to no higher than the PG rating, and dating, social casino and similar ads are blocked. To show and measure ads, Google may collect your device's advertising ID, an approximate location from your IP address, information about ad interactions, and diagnostics. Your products and sales are never passed to the ad SDK. In the European Economic Area, the United Kingdom and Switzerland the app asks for your consent first, and you can change it later under Settings, Privacy choices. You can reset or delete your advertising ID in your Android settings. See how Google uses information from apps that use its services. Pro removes all ads.

Crash reports (Firebase Crashlytics)

If the app crashes or hits a serious error, it sends a crash report to Firebase Crashlytics, a Google service that helps us find and fix the bug. A report contains the error and where it happened in the code, the app version, the device model, the Android version, and a random installation ID that is not linked to you, your Google account or your advertising ID. It never contains your products, your sales or anything that identifies you. Reports are kept for 90 days. See Firebase privacy and security.

Usage statistics (Google Analytics for Firebase)

To learn which features people use and where the app can be better, the app sends a few usage events to Google Analytics for Firebase, such as that a sale was completed (with the payment type: cash, card or other), a receipt was printed or shared, a backup was made, or the Pro offer was shown or Pro was bought. Events never contain amounts, product names, your store name or anything you type. Firebase adds the app version, device model, Android version, country, a random app instance ID and, when ad consent allows it, your advertising ID. Collection follows your choice (Google Consent Mode). We do not use Google signals, we do not send a user ID, and we do not sell this data. In the European Economic Area, the United Kingdom and Switzerland, statistics are only collected if you allow it in the consent form (Settings, Privacy choices lets you change this). Data is kept for 14 months. See Firebase privacy and security.

Purchases (Google Play)

Pro is sold through Google Play Billing, as a subscription (you can cancel it anytime in Google Play) or a one-time purchase. We do not see your payment details; Google Play tells the app only whether Pro is active.

Permissions

Camera, asked the first time you tap scan, to read barcodes on your phone. Nearby devices (Bluetooth), only to talk to the receipt printers you pair; on Android 11 and older Android asks for location for Bluetooth scanning, and the app never reads your location. Product photos are taken with your camera app or chosen with the Android photo picker, and backups are saved with the Android file picker, so no storage permission is needed. Google's ad and purchase libraries add the advertising ID, network state and billing permissions. Internet is used for ads, purchases, crash reports, usage statistics, Wi-Fi printers on your own network and the settings file described above, never for your sales.

Children

The app is not directed at children under 13 and we do not knowingly collect information from them.

Your choices and deleting data

Tillmint has no account and keeps no data on our side. To delete everything Tillmint stores (your products, sales, photos and settings), uninstall the app or clear its storage in Android settings (Apps, Tillmint, Storage). Backup files you saved elsewhere, for example in your Google Drive, stay there until you delete them. If you use Android backup, Android may include this app data in your Google account backup. For ad and statistics data, use Settings, Privacy choices in the app or your Android advertising ID settings. Questions: support@tinyfair.my.id.

Changes and contact

If this policy changes, the new version will be posted on this page with a new date. Questions: support@tinyfair.my.id.
