Klifter Apps ("we", "us", or "our") operates the BillTip mobile application. This Privacy Policy explains how we collect, use, and protect information when you use our app.
BillTip is designed with privacy in mind. We do not require you to create an account, and we do not collect any personal information such as your name, email address, or phone number.
BillTip stores the following data locally on your device only:
This data never leaves your device and is not transmitted to us or any third party.
BillTip uses the following third-party services:
Google AdMob — We display advertisements to users of the free version. AdMob may collect device identifiers and usage data to serve relevant ads. You can review Google's privacy policy at policies.google.com/privacy.
Google Firebase Analytics — We collect anonymous usage analytics (e.g., which features are used, app crashes) to improve the app. No personally identifiable information is collected. You can review Firebase's privacy information at firebase.google.com/support/privacy.
Apple StoreKit — If you purchase BillTip Pro, the transaction is handled entirely by Apple. We do not have access to your payment information.
Frankfurter API — We fetch current exchange rates to display home currency conversions. Only the currency pair is sent in the request — no personal data.
The free version of BillTip displays banner and interstitial advertisements served by Google AdMob. Purchasing BillTip Pro removes all advertisements. AdMob may use device advertising identifiers to serve personalized ads. You can opt out of personalized advertising in your device's privacy settings.
BillTip is not directed at children under the age of 13. We do not knowingly collect any personal information from children.
Since we do not collect or store personal data on our servers, there is no risk of your personal information being compromised through our systems.
If you are located in the European Economic Area (EEA), the United Kingdom, or Switzerland, you have rights under the General Data Protection Regulation (GDPR) and the Swiss Federal Act on Data Protection (DSG), including:
Since BillTip does not collect or store personal data on our servers, there is typically no data for us to provide, modify, or delete. All user preferences are stored locally on your device and can be removed by uninstalling the app.
For data processed by our third-party services (Google AdMob, Firebase Analytics), please contact those providers directly using the links above. You can also opt out of personalized advertising in your device settings under Settings → Privacy → Tracking.
Our legal basis for processing (where applicable through third-party services) is your consent and our legitimate interest in improving the app. You may withdraw consent at any time by disabling tracking in your device settings or by contacting us.
If you have questions about your rights or wish to exercise them, contact us at info@klifter.app.
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
