Privacy Policy
Palabras · Last updated: 13 November 2026
Palabras ("the app") is a Spanish word-of-the-day app made by Álvaro Nieto Cuesta, a sole trader (autónomo) based in Spain ("we"). This policy explains what data the app handles. Short version: there are no accounts, no ads and no tracking across other apps, and your learning progress stays on your device.
Who is responsible for your data
The data controller is Álvaro Nieto Cuesta (autónomo), NIF 03139523T, Calle Dinamarca 3, Portal 2, 3A, 19005 Guadalajara, Spain. Email: nieto.cuesta.alvaro@gmail.com
Data that stays on your device
Your level, goal, settings, learned words, review history, favourites and streak are stored only on your device, so the app and its widgets can work. We can't see them. Deleting the app deletes them. Pronunciation uses your device's built-in text-to-speech, and daily reminders are scheduled on your device.
Purchases (RevenueCat)
Payments are handled by Apple (App Store) or Google (Google Play). We never see your payment details. We use RevenueCat to check whether you have Premium. For this, RevenueCat receives a random anonymous identifier created by the app, your purchase and subscription history, and basic technical data such as device type, operating system, app version, country, and IP address. See RevenueCat's privacy policy.
App performance (Expo Observe)
To find and fix slow or broken parts of the app, it sends performance measurements (for example, how long the app takes to start) and error reports to Expo. These include technical data such as device model, operating system and app version, and a random installation identifier. They don't include your name, email, or learning content. See Expo's privacy policy.
What we don't do
- We don't ask for your name, email, or an account.
- We don't show ads, sell data, or track you across other companies' apps and websites.
- We don't access your contacts, photos, microphone, or location.
Legal basis and retention
We process purchase data to provide the service you paid for (performance of a contract) and performance data for our legitimate interest in keeping the app reliable. RevenueCat and Expo keep data for as long as needed for these purposes, according to their own policies. Some of these providers are outside the EU and use safeguards such as the European Commission's Standard Contractual Clauses.
Your rights
If you're in the EU/EEA or the UK, you can ask to access, correct, or delete your data, object to its processing, or complain to a data protection authority (in Spain, the AEPD). Because we don't know who you are, please include the app's anonymous ID if you have it, or the details of your purchase. Contact: nieto.cuesta.alvaro@gmail.com.
Children
The app isn't directed at children under 13 and doesn't knowingly collect their personal data.
Changes
If this policy changes, we'll update the date above and, for significant changes, tell you in the app.
