Quem Companion Privacy Policy
Effective date: July 19, 2026
Quem Companion is a language-learning and world-companion app for the Quemish language and the world of Trexlin.
This Privacy Policy explains what information Quem Companion collects, how that information is used, when it is shared with service providers, how long it is retained, and the choices available to you.
Quem Companion is provided by M. Tutt Lambert for Trexlin. In this policy, “Quem Companion,” “we,” “us,” and “our” refer to the developer and operator of the app.
For privacy questions or requests, contact:
1. Information We Collect
Account information
You may use some features without creating a registered account.
When the app uses online services for a guest, it may automatically create an anonymous Firebase account. This account is assigned a unique Firebase user identifier but is not initially associated with an email address.
If you register using an email address and password, we process:
Your email address
A Firebase authentication identifier
Authentication and account-status information
Any display name you choose to provide
Authentication is provided through Firebase Authentication. We do not receive or store your password in readable, plain-text form.
Firebase may process technical information such as IP address, user-agent information, and authentication activity to operate authentication, provide security and prevent abuse.
Learning progress and personalization
Depending on the features you use, Quem Companion may store learning and personalization information such as:
Lesson and learning-path progress
Practice history and quiz results
Experience points, levels and streaks
Daily challenge progress
Spaced-repetition and word-review status
Quest and achievement progress
Awards, honors or totems
App preferences and settings
Generated-name history
Your selected Quem identity
Avatar or paper-doll selections
Some of this information is stored only on your device. Some information may be associated with your account and synchronized through Firebase so it can be restored or used across app sessions.
Gahnesh AI tutor
When you use the Gahnesh AI tutor, the text you enter and recent conversation context are transmitted to our Firebase and Google Cloud backend. The backend sends the information needed to generate a response to Google’s Gemini AI service.
This information may include:
Your current message
Recent messages in the current conversation
App-provided language, grammar, dictionary, calendar or lore context
Your Firebase user identifier for authentication, access control and usage limits
Technical request and error information
The app does not currently store your Gahnesh conversation history as a permanent conversation record in our Firestore database. Messages are held in the current app session and transmitted as needed to generate responses. Google and its service infrastructure may process or temporarily retain request information according to the applicable service settings, contracts and policies.
Do not enter sensitive personal, financial, medical, legal or confidential information into the AI tutor.
AI-generated responses may be inaccurate. They are intended for language learning and entertainment and should not be treated as professional advice.
Pronunciation and speech generation
Quem Companion includes recorded and computer-generated pronunciation audio.
When generated speech is needed, pronunciation text may be sent through our backend to one or more speech-generation providers:
ElevenLabs
Amazon Web Services, including Amazon Polly
For eligible multiword pronunciation content, the app may request ElevenLabs-generated audio automatically when the relevant phrase appears on screen. This prefetching reduces the delay if you choose to play the pronunciation. You do not always need to press the Play button before the pronunciation text is transmitted.
Speech providers receive the text and technical request information needed to generate the audio. They do not receive your Apple payment information. Generated audio may be temporarily held in memory or cached on your device to support playback.
Do not place sensitive personal information in text that may be submitted for generated speech.
Word suggestions
Registered users may submit suggested Quemish words or corrections. A suggestion may include:
The proposed English word or phrase
The proposed Quemish word or phrase
A rationale or explanatory message
Your email address
Your Firebase user identifier
Submission date, status and administrative review information
Suggestions are stored in Firebase and may be reviewed by the Quem Companion administrator.
Support messages
If you use the “Ask the Quem” or another in-app support feature, we may collect:
The category you select
The subject and message you submit
Your email address
Your Firebase user identifier
The app version
The operating-system platform
Submission date, response and status information
Support messages are stored in Firebase so we can respond to you, investigate problems and maintain a history of your submitted requests.
Please do not include information in a support message that is not needed to answer your request.
Subscription and purchase information
Subscriptions are purchased and billed through Apple’s App Store and StoreKit.
Apple processes your payment method and billing details. We do not receive your full credit-card number or Apple Account password.
To verify and provide subscription access, the app and our backend may process information supplied by Apple, including:
The subscription product identifier
Transaction and original-transaction identifiers
Purchase, renewal and expiration dates
Trial or introductory-offer information
Subscription status
App Store transaction environment
Signed transaction-verification data
We use this information to confirm subscription access, restore purchases, prevent fraud and provide subscriber features.
Technical, security, and usage information
Our backend and service providers may automatically process limited technical information needed to operate and protect the app, including:
Firebase user identifier
IP address
Request time
Function or feature requested
App and bundle identifiers
Authentication status
Subscription tier
Daily AI or speech usage counts
Error and diagnostic information
Security, fraud-prevention and abuse-prevention information
The current app configuration does not use third-party advertising networks, Firebase Analytics or Firebase Crashlytics.
We may use ordinary server logs and Apple-provided crash or performance reports to maintain app reliability and investigate errors.
2. Information Stored on Your Device
Quem Companion uses local storage, including Apple’s UserDefaults and app-specific files, to save progress, settings, identity choices, audio data and other app state.
Local information generally remains on your device until one of the following occurs:
You clear or reset the relevant information in the app
You delete your Quem Companion account
You delete the app
iOS removes temporary cached information
The app replaces older information with newer information
Deleting the app may remove local information, but it does not automatically delete a registered Firebase account or cancel an Apple subscription. Use the in-app Delete Account feature to delete the account and associated cloud data.
3. How We Use Information
We use information to:
Create, authenticate and maintain accounts
Save and synchronize learning progress
Provide dictionary, practice and learning-path features
Provide the Gahnesh AI tutor
Generate and play pronunciation audio
Verify subscriptions and provide paid features
Apply daily feature limits
Review word suggestions
Respond to support and privacy requests
Detect fraud, misuse and unauthorized access
Diagnose errors and maintain app reliability
Enforce our terms and protect users, the app and our legal rights
Comply with applicable legal requirements
Where applicable law requires a legal basis, we process information as necessary to provide the app and perform our agreement with you, to comply with legal obligations, with your consent where required, and for legitimate interests such as security, fraud prevention, customer support and service reliability.
4. Service Providers and Sharing

5. Advertising, Tracking and Sale of Information
Quem Companion does not currently:
Display third-party advertising
Use third-party advertising networks
Access Apple’s advertising identifier for tracking
Track you across apps or websites owned by other companies
Sell personal information
Share personal information for cross-context behavioral advertising
Use personal information for third-party marketing
If these practices change, we will update this policy and obtain any consent required by law or Apple policy.
6. Data Retention
We retain information according to the following general practices:
Registered account information: retained while your account remains active, unless you delete the account or the information is removed earlier.
Anonymous account information: retained while the anonymous account and its associated app data remain active, unless you delete the account or app data.
Learning progress and personalization: retained locally or in your account until reset, replaced or deleted.
Word suggestions and support messages: retained until your account is deleted or the records are manually removed. They may be retained while needed to review the suggestion, respond to the request, document the response or resolve a dispute.
Daily AI and speech usage records: retained until replaced by a later usage record, deleted as part of account deletion, or removed during routine maintenance.
Subscription information: retained while needed to verify access, respond to billing or support issues, prevent fraud and meet legal or accounting requirements.
Operational and security logs: retained according to our service providers’ configured retention periods and for as long as reasonably needed to investigate reliability, fraud, security or abuse.
When information is no longer needed, we delete or deidentify it where reasonably practicable. Some information may be retained longer when required for legal, security, fraud-prevention, accounting or dispute-resolution purposes.
Third-party providers may retain information according to their own service terms, processing agreements and legally required retention periods.
7. Account and Data Deletion
You may initiate deletion directly inside Quem Companion:
Settings → Account → Delete Account
For a registered email/password account, the app requires password re-entry or recent authentication before deletion. Anonymous guest accounts do not require a password.
Account deletion removes the Firebase Authentication account and associated app-controlled cloud records, including:
The account’s Firebase user record
Data stored under the account’s user document and subcollections
Learning and identity information synchronized under that user record
Word suggestions associated with the user identifier
In-app support messages associated with the user identifier
AI usage-count records
Related account-administration records maintained by the app
The app also signs out the deleted account and clears account-related local progress, cached identity, entitlement state and applicable local preferences.
Some information may be retained where required by law or necessary for security, fraud prevention, accounting or the establishment, exercise or defense of legal claims.
If deletion cannot be completed inside the app, contact privacy@trexlin.net.
Apple subscriptions
Deleting your Quem Companion account does not automatically cancel an Apple subscription.
Apple controls App Store billing. To prevent future renewal charges, manage or cancel the subscription through your Apple Account subscription settings:
https://apps.apple.com/account/subscriptions
Account deletion does not itself create a refund. Refund requests are handled according to Apple’s policies.
8. Your Choices and Rights
Depending on where you live, you may have rights to:
Request access to personal information associated with you
Request correction of inaccurate information
Request deletion of personal information
Object to or restrict certain processing
Request a portable copy of certain information
Withdraw consent where processing is based on consent
Appeal or complain to an applicable data-protection authority
You may exercise account deletion directly in the app. For other privacy requests, email privacy@trexlin.net.
We may need to verify your identity before completing a request. Applicable law may permit or require us to retain certain information or decline part of a request.
You may use limited guest features without registering an email/password account. You may stop using AI or generated-speech features by not using the applicable features, although some pronunciation audio may be prefetched when eligible content appears.
9. International Processing
Quem Companion and its service providers may process and store information in the United States and other countries where they operate.
These countries may have privacy laws different from those in your location. Where required, we and our service providers use appropriate contractual or legal protections for international transfers.
10. Children’s Privacy
Quem Companion is not directed to children under 13 and is not intended for anyone below the age at which local law permits independent consent to online data processing without authorization from a parent or guardian.
We do not knowingly collect personal information from a child in violation of applicable law. If you believe a child has provided personal information improperly, contact privacy@trexlin.net so we can investigate and delete the information where appropriate.
Quem Companion is not presented as an App Store Kids Category app.
11. Security
We use reasonable administrative, technical and organizational measures designed to protect information, including authenticated access, encrypted network transmission where supported, service-provider security controls and restricted backend access.
No electronic transmission or storage system is completely secure. We cannot guarantee that unauthorized access, loss or misuse will never occur.
You are responsible for protecting your password and device access. Contact us if you believe your account has been compromised.
12. Changes to This Policy
We may update this Privacy Policy when the app, our service providers, legal requirements or our information practices change.
We will update the effective date when changes are made. When required by law, we will provide additional notice or request consent before a material change takes effect.
Continued use of the app after an updated policy becomes effective is subject to the updated policy, except where applicable law requires another form of acceptance.
