Privacy Policy
Last updated: May 2, 2026
Boquerón ("the app") is a vocabulary learning app for people learning Spanish. This privacy policy explains what data we collect, how we use it, and your rights.
What we collect
Account information. When you sign up, we collect your email address. We use it to send you a one-time code to log in. We do not store passwords. We do not send marketing emails without your explicit consent.
Vocabulary data. Words you save, definitions, examples, your review history, and the ratings you give your own words. This data is yours and is used only to provide the app's functionality.
Usage data. Basic information about how you use the app (which words you've reviewed, when, and your performance) so the spaced-repetition system can work.
Voice input. When you use Hablar mode, your speech is processed by Apple's on-device speech recognition. The audio itself is not sent to our servers. Only the recognized text (the word you spoke) is processed and discarded.
What we don't collect
- We do not collect your name, address, phone number, or location.
- We do not track you across other apps or websites.
- We do not sell your data to third parties.
- We do not use third-party analytics or advertising trackers.
How we store your data
Your data is stored on Supabase, a cloud database service. Our database uses row-level security to ensure only you can read and modify your own vocabulary data.
How long we keep your data
Your data is kept as long as your account is active. If you delete your account (via the "Eliminar cuenta" option in Settings), your data is permanently removed within 30 days.
Third-party services
The app uses the following third-party services:
- Supabase — database and authentication. https://supabase.com/privacy
- Anthropic Claude API — generates word definitions, examples, and translations from words you save. We send Claude only the word and language context, never your email or other personal information. https://www.anthropic.com/legal/privacy
- Resend — sends authentication emails. https://resend.com/legal/privacy-policy
- Apple Speech Recognition — converts your spoken words to text on your device. Subject to Apple's privacy policy.
Your rights
You can:
- View all your saved vocabulary in the app at any time
- Edit or delete individual words via the word detail screen
- Delete your entire account and all associated data via Settings → "Eliminar cuenta"
- Contact us at [email protected] for any questions or data requests

If we make significant changes to how we handle your data, we'll update this page and notify users via email.
