Privacy Policy
Last updated: March 28, 2026
Keloud ("we", "our", or "us") built the Kalcer app as a Freemium app. This page informs you of our policies regarding the collection, use, and disclosure of information when you use our app.
Information Collection and Use
Data Stored Locally
Kalcer stores the following data only on your device (locally):
- Calculator expressions and history
- Item names, prices, descriptions, and colors
- Receipt settings (store name, address, phone, logo)
- Saved printer preferences (Bluetooth device name and address)
- App preferences (language, currency, user tier)
This data is never transmitted to our servers. We do not have servers that collect your personal data.
Third-Party Services
Kalcer uses the following third-party services that may collect information:
Google AdMob
Displays banner and interstitial advertisements to free-tier users. AdMob may collect device identifiers, IP address, and usage data for ad personalization.
