This Privacy Policy describes how Lexible LLC ("Lexible," "we," "us," or "our") collects, uses, and protects information when you use the Lexible mobile application (the "App"). Lexible is a reading support application designed for children with dyslexia. Because our App is used by children, we take privacy very seriously and are committed to complying with the Children's Online Privacy Protection Act ("COPPA") and other applicable privacy laws.
Your use of the App and our website is also governed by our Terms of Service.
1. Information We Collect
1.1 Account Information
Parent or guardian accounts are required to use Lexible. Children do not create their own accounts. When a parent or guardian creates an account, we collect:
Parent/guardian email address
Child's first name or nickname (for personalization)
Child's age or grade level
1.2 Reading and Usage Data
When your child uses the App, we collect data to provide reading support and track progress, including:
Recordings of your child reading aloud, which we store on our servers to measure your child's reading and to train and test Lexible's own speech recognition model, so it hears children more accurately (see Section 2.1). Speech recognition runs on the device and on Lexible's own servers. Recordings are never sent to a third-party speech recognition service, never given to another company to train its models, and never sold.
Your child's conversations with Runa, the App's reading companion. Speech is turned into text on the device, and the text is sent to an AI service without your child's name or your account details.
Reading performance data (e.g., words read, accuracy, fluency metrics)
Interaction data with the App's scaffolding and support features
Reading session duration and frequency
Book selections and progress within books
1.3 Device and Technical Data
We automatically collect certain technical information, including:
Device type and operating system version
App version
Crash logs and performance data
General usage analytics
Your device's IP address, which our servers receive with every request. We use it to work out which country you are in, so the App shows only the books available there. We record the country, never the IP address itself (see Country Lookup in Section 3).
2. How We Use Information
We use the information we collect for the following purposes:
To provide real-time AI-powered reading support and scaffolding
To analyze reading performance and generate progress reports for parents
To adapt the difficulty and type of support provided to your child
To show only the books that are available in your country
To improve the App's features, accuracy, and effectiveness
To train and test Lexible's own speech recognition model with recordings of children reading, so it understands children's voices more accurately (see Section 2.1)
To diagnose technical issues and improve App stability
To communicate with parents about their account or the App
2.1 Training Our Speech Recognition Model
We use recordings of children reading aloud to train and test Lexible's own speech recognition model. Here is exactly what that means.
The model only recognizes speech. It listens to a child reading and writes down the sounds it hears, as letters and symbols, so the App can tell which words were read correctly.
The model cannot reproduce your child's voice. It does not make any sound, so it cannot create, copy, or imitate your child's voice or anyone else's. It does not contain any recordings. We never use recordings to create a synthetic voice or a voice clone, and we never use them to create a voiceprint or to identify who is speaking.
People who check recordings. A small number of Lexible team members listen to some recordings before training, to choose clear ones and to check that their sounds are labeled correctly.
Where training happens. Training happens only on computers that Lexible owns and controls, in the United States. Copies of recordings used for training are kept in one place and deleted when the training work is done. Recordings are never given to another company to train its models, and never sold.
The trained model. The trained model is built into the App, so it runs on the devices of every family that uses Lexible. It contains no recordings, names, email addresses, or account details. Lexible owns the model and may license or sell it, or technology built on it. Doing so never includes recordings or any personal information.
What the model hears is part of your child's reading data. When the model listens during reading, the sounds it hears are saved with your child's reader profile as part of their reading performance data (Section 1.2), so we can show progress and adapt support.
Deleting recordings. When you delete a reader or your account, that reader's recordings are deleted and are never used in future training. A model trained before the deletion is not changed, and it does not contain the recordings.
3. Third-Party Services
Lexible uses the following categories of third-party services to operate the App:
Cloud Infrastructure: We use Amazon Web Services (AWS) to securely store and process data.
Country Lookup: To show only the books available in your country, our servers look up the country of your IP address in a database from MaxMind that is kept on our own servers. Your IP address is never sent to MaxMind, and we keep only the country it gives us. This product includes GeoLite Data created by MaxMind, available from https://www.maxmind.com.
Speech Recognition: Your child's speech is recognized on the device, by Lexible's built-in speech recognition model and Apple's on-device speech recognition. Lexible's model also runs on computers Lexible owns and controls when we train and test it (see Section 2.1). Recordings are stored only on our own servers (see Cloud Infrastructure) and are never sent to, or shared with, a third-party speech recognition service.
AI Language Models: We use third-party AI language model services to power the App's reading support features and Runa's conversations. We never send these services your child's name, your email address, or any account details. We send only what is needed to generate support and feedback: de-identified reading content, performance data, and the text of your child's conversations with Runa.
Runa's Voice: We use a third-party text-to-speech service to give Runa a voice. It receives only the text the App speaks aloud, such as Runa's lines and book narration, and never your child's voice or account details.
Diagnostics and Crash Reporting: We use third-party services to collect crash reports, logs, and performance data so we can find and fix problems with the App.
Website Analytics: Our website, lexible.com, uses Google Analytics to understand how visitors use the site. The App does not use Google Analytics.
reCAPTCHA: Our website uses Google reCAPTCHA for security purposes, which is governed by Google's Privacy Policy and Terms of Service.
We do not sell, rent, or share your personal information with third parties for their own marketing or advertising purposes.
4. Children's Privacy (COPPA Compliance)
We are committed to protecting the privacy of children. In compliance with COPPA:
Only parents or guardians may create accounts. We require verifiable parental consent before collecting any information from children under 13.
We collect only the information necessary to provide the App's reading support services.
We do not condition a child's participation on providing more information than is reasonably necessary.
Parents may review, request deletion of, or refuse further collection of their child's information at any time by contacting us at privacy@lexible.com. Parents can also delete a reader profile, or their whole account, directly in the App (see Section 6).
No personally identifiable information from children is shared with third parties except as necessary to provide the App's core functionality as described in Section 3.
5. Data Storage and Security
All data is stored on Amazon Web Services (AWS) servers located in the United States, except the training copies of recordings described in Section 2.1, which are kept on a computer Lexible owns and controls in the United States. We implement industry-standard security measures to protect your information, including encryption in transit and at rest, access controls, and regular security reviews. Voice recordings are kept in their own storage, separate from other data. They are encrypted while they travel from the device to our servers, and they are stored encrypted with a dedicated key.
6. Data Retention and Deletion
We keep voice recordings for 2 years after they are recorded, then delete them automatically. We keep your account information, your child's reading progress, and conversations with Runa for as long as your account is active, so Runa can pick up where your child left off and you can see their progress.
6.1 Deleting a Reader or Your Account in the App
You can delete a reader profile or your entire account at any time from the menu in the App. Deleting requires Face ID, Touch ID, or your password, so a child can't do it by accident. Deletion is permanent and cannot be undone.
Deleting a reader deletes that child's voice recordings and their name, and closes their reader profile.
Deleting your account deletes the voice recordings of every reader on the account, your children's names, your email address, and your login, and signs you out on all of your devices.
After a deletion, we keep reading performance data (such as words read and accuracy) and the text of your child's conversations with Runa, with no name, email address, or login attached. We use this de-identified data only to improve Lexible's reading support.
6.2 Deleting by Request
You may also request deletion of your data at any time by contacting us at privacy@lexible.com. Upon receiving a verified deletion request, we will delete your data within 30 days, except where we are required by law to retain it.
