Cattongue — Privacy Policy

Last updated: November 14, 2026

Cattongue ("we", "our", "us") operates the Cattongue mobile application (the "App"), an app that helps children learn Arabic. The App is meant to be set up by a parent or guardian, who creates the account and uses it with their child. This policy explains what information we collect, why, who we share it with, and the choices you have.

1. Information we collect

Account information (given by the parent)

  • Email address: to create the account, sign in, and reply to support requests.
  • Password: handled and encrypted by Firebase Authentication (Google). We never see it.
  • Child's first name or nickname, gender and avatar: to personalize the App and to adapt instructions to masculine or feminine Arabic forms.

Learning progress

  • Your child's position in the lessons, rewards, scores and saved games, so that learning can continue on any device signed in to the account.

Usage counts

  • Simple counts of which sections and exercises are used (for example "lesson visited", "game started"), grouped by month. They help us improve the content. They are not used for advertising and are not shared with advertisers.

Support messages

  • When you write to us from the App's Support screen: the name you enter, your email address, your message, and any screenshot you choose to attach.

Microphone

  • Some exercises (pronunciation, and reciting the Quran in the Quran section) use the microphone to check what the child says.
  • The microphone is used only while one of these exercises is open: either after the child taps the microphone button, or, in Quran recitation mode, automatically for the current verse (a visible indicator shows when it is listening).
  • Speech is turned into text by the phone's speech recognition. When the device supports it, this happens on the device. Otherwise, it is processed by the speech service of the phone's operating system (Apple or Google) under their own privacy policies.
  • We do not record, store or upload your child's voice.

2. How we use information

  • To provide the App and keep the child's progress.
  • To answer support requests.
  • To improve lessons and fix problems (usage counts, technical errors).
  • To tell you about important changes to the App.

We do not sell personal information. We do not show personalized advertising and do not build advertising profiles.

3. Service providers and third parties

We use these providers to run the App:

  • Google Firebase (authentication, database, cloud functions): stores account and progress data.
  • Our own storage server (Hetzner, Falkenstein, Germany): hosts the App's pictures and sound files.
  • SparkPost: sends emails (account verification, support replies).
  • Quran Foundation (Quran.com): the Quran section plays recitations provided by the Quran.com API. To get them, our server asks Quran.com for the recitation of a surah. Your phone then downloads the audio file from Quran.com's servers, which, like any website, receive the phone's IP address. No personal information about you or your child is sent to Quran Foundation. The recitation data is kept on the phone for 6 days at most, then fetched again.

4. Children's privacy

  • The App is designed for children, used with a parent or guardian. The account is created by the parent.
  • We collect only what is needed for the child to learn: a first name or nickname, gender, avatar and progress. We do not ask for the child's full name, address, photo or contact details.
  • We do not use children's data for advertising, profiling or training machine-learning models.
  • A parent can ask at any time to see, correct or delete their child's information (see section 6).

5. How long we keep information

  • Account and progress data: as long as the account exists. When an account is deleted, its data is deleted.
  • Support messages: as long as needed to handle the request.
  • Quran recitation data from Quran.com: 6 days at most on the phone.

6. Your rights and choices

You can, at any time:

  • ask for a copy of your data, or ask us to correct it;
  • delete your account and its data, by writing to contact@cattongueapp.com from the account's email address;
  • refuse microphone access in the phone's settings. The microphone exercises then can't be used, but the rest of the App still works.

Depending on where you live (for example in the European Union, the UK or California), you may have additional rights under local law. Contact us to use them. You may also complain to your data protection authority.

7. Security

We take reasonable measures to protect your information: encrypted connections (TLS), passwords handled by Firebase, secret keys kept on our servers only, and restricted access. No method of transmission or storage is completely secure. If a security incident affects your data, we will inform you and, when required, the relevant authorities and partners.

8. Changes to this policy

We may update this policy. Changes are posted on this page with a new "Last updated" date, and important changes are announced in the App.
