Tildo

Learn Spanish, word by word.

Privacy Policy

Last updated: October 13, 2026

1. Introduction

This Privacy Policy describes how Tildo ("we", "us", or "our") collects, uses, and protects your personal information when you use the Tildo mobile application for learning Spanish ("App"). By using the App, you agree to the collection and use of information in accordance with this policy.

2. Information We Collect

2.1. Account information. When you create an account, we collect:

  • Your display name
  • Your email address
  • Your password, if you register with email and password (stored only in hashed form by Firebase Authentication — we never see it)
  • If you use Sign in with Apple (iOS) or Google Sign-In (Android): the account identifier and the name and email address the provider shares with us. With Sign in with Apple you may choose to hide your email; we then receive an Apple relay address.

2.2. Learning and usage data. To run the App we store:

  • Words you have studied and your progress by level and category
  • Progress in grammar rules and practice exercises
  • Daily streaks, streak freezes, points and experience
  • Word battle results, rankings, friends list and friend requests
  • Settings such as interface language, learning goal and widget preferences

2.3. Device information. We may collect the device type, operating system version, app version and language preferences.

2.4. Microphone and speech recognition. Some exercises let you say a Spanish word aloud. Only when you start such an exercise and grant permission, the App uses your device’s microphone and the speech recognition service of your platform (Apple on iOS, Google on Android) to compare what you said with the expected word. We do not record, store or upload your voice to our servers. Your platform provider may process the audio under its own privacy policy.

2.5. Lock screen and home screen widget. If you add the Tildo widget, a small set of words and their translations is stored locally on your device so the widget can display them. This data stays on your device.

2.6. Subscriptions and purchases. When you buy or restore a subscription:

  • Apple or Google processes the payment; we never receive your payment card details.
  • We use RevenueCat, Inc. (“RevenueCat”) to validate subscriptions and keep Premium access in sync across your devices. RevenueCat may receive your app user identifier (linked to your account), product identifiers, subscription status, purchase and renewal dates, store transaction identifiers and the device or app information needed to provide its service.
  • Local counters (for example, the number of free study sessions used today) may be stored on your device to apply free-plan limits.

3. How We Use Your Information

We use the information we collect to:

  • Create and manage your account and let you sign in
  • Send the email verification message and important account notifications
  • Save your learning progress and show statistics
  • Run social features: friends, word battles, points and rankings
  • Provide and verify Premium access
  • Show advertising to users without Premium (see Section 4)
  • Keep the App secure, fix errors and improve the learning experience

4. Advertising

4.1. Users without Premium see ads served by Google AdMob (Google Mobile Ads SDK). Premium users do not see ads.

4.2. AdMob may use:

  • Device identifiers where permitted (on Android, the Advertising ID)
  • IP address and approximate location (country or region)
  • App interaction and device information (type, OS, screen size)

4.3. On iOS, the App does not ask for permission to track you, so Apple’s advertising identifier (IDFA) is not shared with advertisers; ads may still be selected based on context and approximate location. On Android, you can reset your Advertising ID or turn off ad personalisation in Settings > Google > Ads.

4.4. Google’s use of data is described here: https://policies.google.com/technologies/partner-sites

5. Service Providers and Data Storage

5.1. Your account and learning data are stored with Google Firebase (Firebase Authentication and Cloud Firestore, operated on Google Cloud Platform), which uses industry-standard security measures.

5.2. Verification and account emails are sent through our own server using the email delivery provider Resend. They receive only your email address and the content of the message.

5.3. Subscription data is processed by RevenueCat (Section 2.6) and advertising by Google AdMob (Section 4).

5.4. Some providers process data outside your country, including in the United States. Where required, such transfers rely on appropriate safeguards such as the European Commission’s Standard Contractual Clauses.

5.5. No method of electronic transmission or storage is 100% secure, but we take reasonable measures to protect your information.

6. Data Sharing

We do not sell your personal information. We share data only:

  • With other users: your display name, points, streak and ranking are visible to other users and your friends
  • With the service providers listed in Section 5, only to operate the App
  • With Apple or Google, as required to process purchases and sign-in
  • When required by law or to protect our rights and the safety of users

7. Your Rights

You can:

  • View and edit your profile in the App
  • Delete your account and associated data at any time in Settings inside the App
  • Opt out of personalised advertising (Section 4.3)
  • Request a copy of your data or ask any privacy question by email (Section 11)

If you are in the EU/EEA or the UK, you also have the right to data portability, to restrict or object to processing, and to lodge a complaint with your data protection authority (in Spain, the Agencia Española de Protección de Datos).

8. Children’s Privacy

The App is not intended for children under 13 (or the higher minimum age required in your country). We do not knowingly collect personal information from children under that age. If you believe a child has provided us with personal data, please contact us and we will delete it.

9. Data Retention

We keep your data while your account is active. When you delete your account in the App, your profile, progress, friends and related records are deleted, normally immediately and in any case within 30 days, except where we must keep data by law. Unverified email accounts may be removed after a period of inactivity.

10. Changes to This Policy

We may update this Privacy Policy from time to time. We will inform you of significant changes in the App. The date at the top shows when it was last updated.
