FayJuno Privacy Policy

Last updated: October 10, 2026
Effective date: October 10, 2026

This English version is provided for your convenience. If there is any inconsistency between the Chinese and English versions, the Chinese version shall prevail.

The FayJuno (法语菌) app, the official website (french.egg404.com) and related services (collectively, the "Service") are operated by Luzhou Shanhe Network Technology Co., Ltd. ("we", "us" or "our"). We understand how important your personal information is to you, and we process it in accordance with the Personal Information Protection Law of the People's Republic of China and other laws and regulations, following the principles of lawfulness, legitimacy, necessity and good faith.

This policy explains what personal information we collect and why, how we use cookies and similar technologies, how we share and entrust processing, how we store and protect information, your rights, how we protect minors and how to contact us. Please read it carefully before using the Service, especially the sensitive personal information and key terms shown in bold.

1. Our basic commitments

• When you first launch the app, a pop-up asks you to read this policy. Until you agree, we only go online to load public learning content. We do not request camera, photo library, microphone, notification or other system permissions, do not initialise third-party SDKs and do not collect device information or other personal information.
• After you agree, each system permission is requested separately only when you use the related feature, and you can turn it off at any time in system settings. Turning off a permission does not affect other features.
• Self-start and associated start: This app does not self-start without your consent, and is not launched by other apps without a reasonable use case. Home-screen widgets appear only after you add them; study data syncs when you open the app; the system may redraw cards locally on a long interval without going online; background audio and notifications run only while you are listening. See “System permissions” below.
• We do not sell your personal information.

2. Personal information we collect and use

2.1 Registration and sign-in

• Email sign-in: We collect your email address and the password you set (stored as an irreversible hash) to send verification codes, sign you in, reset your password and create and identify your account.
• WeChat sign-in: With your authorisation, we obtain your WeChat OpenID, UnionID, nickname, avatar and gender through the WeChat Open Platform to create or link your account. On first registration your WeChat nickname and avatar are used as your initial profile, which you can change at any time.
• Sign in with Apple: With your authorisation, we obtain the unique user identifier provided by Apple to create or link your account, and generate a random nickname for you.
• QQ sign-in: With your authorisation, we obtain your QQ OpenID, UnionID, nickname, avatar and gender through QQ Connect to create or link your account. On first registration your QQ nickname and avatar are used as your initial profile, which you can change at any time.
• Google sign-in: With your authorisation, we obtain the unique account identifier, email address, name and avatar provided by Google to create or link your account. On first registration your Google name and avatar are used as your initial profile, which you can change at any time.
• Invite code (optional): You may enter an invite code when registering so that invitation rewards can be issued.

2.2 Profile

You may choose to set a nickname, avatar, gender, mobile number (optional) and age. Your nickname, avatar and gender are shown to other users in public places such as study leaderboards, community definitions, notes and user pronunciations. Your mobile number is used only for your profile and necessary contact and is never made public. Your age is stored only on your device and is not uploaded to our servers. Leaving any of these blank does not affect your use of the Service.

2.3 Account security and multi-device management

To keep your account secure, limit the number of signed-in devices per account and provide the Device management feature, after you sign in we collect: a device identifier (a device UUID generated by the app), device model, device name, operating system and version, app version and build number, the app store it was installed from, system language, time zone, IP address, and sign-in and last active times. The Device management page shows an approximate sign-in region inferred from the IP address. In addition, server access logs record IP addresses and other network information for security auditing and troubleshooting and are kept for 30 days.

2.4 Learning services

• Study data: Study plans, vocabulary learning and review records (including answer time, mode and duration), favourites, word lists, reading progress, study time, check-ins and streaks, and points are used to provide learning features, multi-device sync, study statistics and leaderboards. The top 100 on the study leaderboard are shown publicly with nickname, avatar and gender.
• Text you enter or submit: When you look up words, translate, check grammar or get writing feedback, we process what you enter to return results. Translation results are cached without being linked to your account to improve speed. The original text and results of grammar checks are stored linked to your account for 30 days so you can view your history, and are deleted automatically afterwards.
• Clipboard: We read clipboard text only when you tap the "Paste" button on the translation or grammar check page. We never read it in the background.
• Recording (microphone): When you use read-aloud, user pronunciation or pronunciation assessment, we use the microphone with your authorisation. Read-aloud recordings of reading passages are kept only on your device. Read-aloud recordings made during vocabulary learning are uploaded to and stored on our servers and, once reviewed, shown to other users as "user pronunciations"; you can delete them at any time. Pronunciation assessment recordings are sent directly by the app to a third-party assessment service (see Section 4) for scoring, with the user identifier de-identified.
• Home page weather: To show the weather for your city on the home page, the app sends your network IP address to third-party IP geolocation services (geojs.io, ipwho.is) to estimate your approximate city, then sends approximate coordinates to a weather service (open-meteo.com) to get the weather. We do not request location permission and do not store this location on our servers.
• French radio: When you listen to French radio, the app uses the radio feature to search for station streams.
• Local network (iOS): When you use "Import word lists from computer", with your authorisation the app receives word list files sent from a computer on the same Wi-Fi network, and stops receiving once you close the import page.

2.5 Content you publish

Community definitions, word notes, user pronunciation recordings, feedback and complaints (which may include images) and other content you publish are uploaded to and stored on our servers. Public content is shown to other users together with your nickname and avatar. We apply sensitive-word filtering and review to public content.

2.6 Membership and payment

• When you buy membership, we create an order and record the order number, product, amount, payment channel, payment status and time. Payments are processed by Alipay, WeChat Pay, Apple or Google, and we do not collect sensitive payment information such as your bank card number or payment password. For Apple / Google purchases, we receive transaction receipts to verify orders and grant benefits.
• Education discount verification: If you apply for education membership, you must submit your real name, school name, ID number (student or teacher ID number, etc.) and photos of supporting documents (student ID, proof of enrolment or teacher qualification certificate). This is sensitive personal information used only to manually verify that you are a current student or teacher, and we keep it only for as long as necessary for review and fulfilment.
• When you take part in group deals, invitations, points redemption or other campaigns, we record participation, invitation relationships and point transactions for campaign settlement and anti-fraud purposes.

2.7 System permissions

Permission	Used for	If not granted
Microphone	Read-aloud recording, user pronunciation, pronunciation assessment	Recording features are unavailable
Camera	Taking an avatar photo, photographing education verification documents	You can't take photos but can use the photo library instead
Photos / storage (read images)	Choosing an avatar, uploading verification documents or feedback screenshots, saving images to the photo library	You can't choose or save images
Notifications	Showing playback controls in the notification area during French radio and background audio playback	You can't control playback from notifications

We do not request access to your location, contacts, SMS, call logs or similar permissions.

Self-start and associated start: This app does not frequently self-start without your consent, and is not associated-started by other apps without a reasonable use case:

• Home-screen widgets: Shown only after you add them. Personal study and leaderboard data sync into a local snapshot when you open the app. The system may redraw cards locally on a long interval (about 12 hours for quotes, about 30 minutes for study progress) to refresh the day display; that redraw does not access the network or collect new personal information.
• Background audio: Foreground service and notification controls run only while you actively listen to French radio or audio, and stop when you stop listening. We do not allow other apps to launch us via media-button broadcasts while idle.
• Other cases: We do not register boot-completed receivers, and do not wake the process for push or analytics without your consent.

By agreeing to this policy, you confirm that you have read and understood these permission and startup disclosures.

2.8 Analytics and diagnostics

After you agree to this policy, we use Firebase (see Section 4) to collect page view and feature usage events, app crash logs and network request performance data, together with the related account ID, membership level, sign-in method, device model, OS version, app version, app instance identifier and similar information. When an error occurs in the app, the error message and version number are also reported to our servers. This data is used to analyse product usage and to locate and fix problems, and does not include the learning content you enter.

2.9 Exceptions to consent

Under applicable laws and regulations, we may process your personal information without your consent where necessary to conclude or perform a contract to which you are a party, to fulfil statutory duties or obligations, to respond to public health emergencies or protect the life, health and property of natural persons in emergencies, to process personal information that has already been made public within a reasonable scope, and in other legally specified circumstances.

3. Cookies and similar technologies

On the website, we use your browser's local storage to keep you signed in. In the app, we store sign-in credentials, study settings and caches locally on your device so you don't need to sign in repeatedly and content loads faster. You can clear this data by signing out, clearing the cache or uninstalling the app.

4. Entrusted processing, sharing, transfer and public disclosure

4.1 Third-party SDKs and services

To provide certain features, we integrate the following third-party SDKs or services. All third-party SDKs are initialised only after you agree to this policy and process only the necessary information when you use the related feature:

• Cloud services: Our servers, databases and file storage use cloud services provided by Alibaba Cloud Computing Co., Ltd. Avatars, feedback images, education verification documents, user pronunciations and similar data are stored on our servers and Object Storage Service (OSS) at Alibaba Cloud.
• Content processing services: For translation, grammar checking, writing feedback, definition and example completion, and read-aloud audio generation, the text you submit or the learning text to be read aloud (without your account, nickname or other identity information) is sent to technical service providers we engage for processing and the results are returned. Generated read-aloud audio is cached in our object storage for repeated playback.
• Email delivery: Verification codes are sent to your email through Alibaba Cloud's enterprise email service.
• Internal operational notifications: Necessary information about top-ups, refunds and abnormal access alerts (such as order number, amount, account ID, nickname and IP address) is pushed to our internal work group on Feishu (Beijing Feishu Technology Co., Ltd.) so that orders can be handled promptly and the Service kept secure.

We require entrusted parties by contract or similar means to process personal information only for the purposes and in the manner we specify and to take the necessary security measures.

4.3 Sharing, transfer and public disclosure

Except as described above, we do not share your personal information with third parties unless we obtain your separate consent or are required to do so by laws, regulations, judicial or administrative authorities. If personal information needs to be transferred because of a merger, division, dissolution, bankruptcy or similar event, we will inform you of the recipient's name and contact details and require it to continue to fulfil the obligations in this policy. Except for public content you choose to publish, we do not publicly disclose your personal information.

5. Storage of personal information

1. Location: Personal information we collect and generate within the People's Republic of China is in principle stored within China. Please note, however, that Firebase analytics and crash analysis, Apple and Google sign-in and payment, and the IP geolocation and weather services used for home page weather are provided by entities outside China, so the related data may be transferred abroad for processing. We will take the measures required by laws and regulations to keep such data secure.

2. Retention period: We keep your personal information only for the shortest period necessary to achieve the purposes described in this policy. After your account is deleted, we will delete or anonymise your personal information within the period required by law. Where laws and regulations require retention (for example, transaction records must be kept for at least three years and network logs for at least six months), we will keep the information securely for the required period and then delete or anonymise it.

3. Cessation of operations: If we stop operating the Service, we will promptly stop collecting your personal information, notify you individually or by announcement, and delete or anonymise the personal information we hold about you, unless otherwise required by law.

6. Security of personal information

We protect your personal information with HTTPS encrypted transmission, API signature verification, hashed password storage, access controls, security audits and other measures to prevent unauthorised access, disclosure, alteration or loss. In the unfortunate event of a personal information security incident, we will promptly inform you, as required by law, of the basic facts, possible impact, the measures we have taken or will take, and suggestions on how you can protect yourself, and report it to the competent authorities.

7. Your rights

• Access and copy: You can view your profile and study data on the Me, Edit profile, Study statistics and other pages in the app. To obtain a copy of your personal information, contact us using the methods in Section 10.
• Correction and completion: You can change your nickname, avatar, gender, age and other information under Edit profile.
• Deletion: You can delete notes, definitions and other content you have published, and in circumstances provided by law you can ask us to delete your personal information.
• Withdrawal of consent: You can turn off the relevant permissions in system settings, or contact us to withdraw your consent to this policy. After withdrawal we will stop processing the corresponding personal information, but this does not affect processing carried out on the basis of your consent before withdrawal.
• Account deletion: You can request deletion under Me > Edit profile > Account security > Delete account. There is a 7-day grace period after submission during which signing in again cancels the request. After 7 days the account is permanently deleted and we will delete or anonymise your personal information, unless otherwise required by law.
• Explanations and complaints: You have the right to ask us to explain our personal information processing rules, and you can file a complaint through Feedback & complaints in the app or the methods in Section 10.

For security reasons we may need to verify your identity first. We will respond within 15 working days of receiving your request and verifying your identity.

8. Protection of minors

We attach great importance to protecting minors' personal information. If you are a child under 14, please use the Service under the guidance of a parent or guardian after they have read and agreed to this policy. We process children's personal information only where permitted by law, with parental consent or where necessary to protect the minor. If a parent or guardian finds that we have processed a child's personal information without consent, please contact us and we will delete it as soon as possible.

9. Updates to this policy

We may update this policy from time to time. The updated policy will be published in the app and on the website. For material changes (such as changes to the purposes or methods of processing or the types of personal information, new third-party sharing, or changes to how you can exercise your rights), we will notify you through pop-ups, inbox messages or other prominent means and, where necessary, ask for your consent again.
