for the TipCounter mobile application
Last updated: May 5, 2026
The TipCounter mobile application ("the App") is developed and operated by Sommer Media s.r.o., a company registered in the Czech Republic, with its registered office at Oldřichovice 738, 739 61 Třinec, Czech Republic. Company Registration No. (IČO): 27760766. VAT ID: CZ27760766. Privacy contact: privacy@sommer.media. General contact: app@sommer.media.
We respect your right to privacy and protect your data. This policy explains what information the App processes, why we process it, the legal basis for processing, and the rights you have under the General Data Protection Regulation (GDPR / EU 2016/679).
Consent to terms
By using TipCounter you agree to this privacy policy. If you do not agree, please do not use the App.
Data collection
Personal data
TipCounter requires no sign-up, no user accounts, and we do not collect direct personal data such as name, email, or phone number.
Local data
Saved calculations, history, settings, and usage counters are stored exclusively on your device using AsyncStorage. This data never leaves your phone and is removed when you uninstall the App.
Crash reporting and analytics
The App uses Firebase Crashlytics and Firebase Analytics (Google LLC) for anonymous crash reporting and aggregate usage analytics. Processed data includes: device model, OS version, timestamps, app version, stack traces of crashes, and anonymous interaction events (e.g. "calculation_done", "paywall_opened"). None of this can be used to identify a specific person.
Legal basis: legitimate interest (Article 6(1)(f) GDPR) - improving stability and quality of the App.
Retention: crash reports and analytics are retained according to Firebase defaults (up to 14 months).
Advertising
The free version of the App displays banner ads served by Google AdMob (Google LLC). AdMob may use a unique advertising identifier to serve relevant ads, frequency-cap, and detect fraud. In the European Economic Area, the United Kingdom and California you will see a consent dialog on first launch where you can accept or refuse personalised ads. You can change this choice anytime in Settings -> Manage ad preferences.
Legal basis: consent (Article 6(1)(a) GDPR) for personalised ads; legitimate interest for non-personalised ads. Pro users do not see ads.
Feedback
If you submit written feedback through the in-app rating prompt, your message and rating are sent to our Firebase Firestore database with a timestamp. We do not associate this content with any device identifier and we cannot identify the sender. Feedback is used solely to improve the App.
International data transfers
Some of our processors (Google LLC, RevenueCat, Apple Inc.) operate servers outside the European Economic Area, including in the United States. Such transfers are governed by Standard Contractual Clauses (SCC) under Article 46 GDPR and the EU-U.S. Data Privacy Framework where applicable.
Purchases
The Pro lifetime one-time purchase is processed by RevenueCat (RevenueCat, Inc., U.S.) and the Apple App Store / Google Play. We only see an anonymous purchase status, not your payment details or identity.
Children's privacy
TipCounter is rated 4+ but is not directed at children under 16. We do not knowingly collect data from children under 16. If you believe a child has provided data through the App, please contact us at privacy@sommer.media and we will remove it.
Your rights under GDPR
You have the right to:
- Access your data and request a copy (Article 15)
- Request correction of inaccurate data (Article 16)
- Request erasure of your data (Article 17)
- Restrict processing (Article 18)
- Data portability (Article 20)
- Object to processing based on legitimate interest (Article 21)
